The objective of this study is to evaluate psychiatric symptoms in Parkinson's disease (PD) patients and to assess their relation with other clinical aspects of PD. Psychotic symptoms (PS) and compulsive symptoms (CS) as well as other nonmotor and motor features were evaluated in 353 PD patients. Psychotic and compulsive symptom scores did not correlate significantly. PS occurred in 65% of patients, with item frequencies ranging from 10% (paranoid ideation) to 55% (altered dream phenomena). Regression analysis showed that autonomic impairment accounted for 20% of the 32% explained variance of PS, whereas cognitive problems, depression, daytime sleepiness, and dopamine agonist (DA) dose explained the rest. CS occurred in 19%, with item frequencies of 10% for both sexual preoccupation and compulsive shopping/gambling. Patients with more severe CS (score > or = 2 on one or both items) were significantly more often men, had a younger age at onset, a higher DA dose and experienced more motor fluctuations compared to the other patients. PS and CS are common but unrelated psychiatric symptoms in PD. The relations found between PS and cognitive problems, depression, daytime sleepiness, and autonomic impairment suggests a resemblance with Dementia with Lewy Bodies. The prominent association between PS and autonomic impairment may be explained by a shared underlying mechanism. Our results confirm previous reports on the profile of patients developing CS, and mechanisms underlying motor fluctuations may also play a role in the development of CS in PD.

Full Text Available Psychotic symptoms following acquired brain lesion are relatively rare, and thus, the specific association linking such symptoms to the distinct brain structure remains unclear. The frontal–subcortical circuits are thought to modulate motor activity and human behavior, and have been reported to be associated with many neuropsychiatric symptoms. We herein report the case of a 77-year-old man without previous psychiatric disorder who developed a new onset of psychotic symptoms following left caudate infarction. The presented case supports the fact that psychosis might arise from alteration of the distinct brain structure. The functional impairment of the frontal–subcortical circuits may be a critical factor linking the pathogenesis of psychosis associated with acquired brain lesion.

Cocaine use is known to induce transient psychotic symptoms. We evaluated retrospectively the lifetime prevalence of cocaine-induced psychotic symptoms in 105 cocaine addicts with the French version of the Scale for Assessment of Positive Symptoms-Cocaine Induced Psychosis (SAPS-CIP) in a clinical setting. Most patients (86.5%) described such symptoms. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

The aim of this study is to compare the clinical characteristics of three groups of patients in treatment for cocaine dependence: patients without any psychotic symptoms (NS), patients with transient psychotic symptoms (PS) and patients with cocaine-induced psychotic disorder (CIPD). An observational and retrospective study of 150 cocaine-dependent patients undergoing treatment in the Drug Unit of the Psychiatry Department of University Hospital Vall d׳Hebron in Barcelona (Spain) using these three groups, NS, PS and CIPD, was performed. All patients were evaluated with the PRISM interview. ANOVA, χ2 tests and multivariate multinomial regression analysis were used to perform statistical analyses. Seven patients with a primary psychotic disorder were discharged. Forty-six patients (32.1%) did not report any psychotic symptoms. Ninety-seven patients (67.9%) presented with a history of any cocaine-induced psychotic symptom and were considered as the cocaine-induced psychotic (CIP) group. Among them, 39 (27.3%) were included in the PS group and 58 (40.6%) were included in the CIPD group. A history of imprisonment was found significantly more frequently in the PS group than in the NS group. The distribution of age at onset of dependence, lifetime cannabis abuse or dependence and imprisonment were significantly different between the NS and CIPD groups. We conclude that in cocaine-dependent patients, clinicians should be advised about the risk of development of psychotic symptoms. The presence of some psychotic symptoms could increase the potential risks of disturbing behaviours. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Psychotic symptoms are common in children and adolescents and may be early manifestations of liability to severe mental illness (SMI), including schizophrenia. SMI and psychotic symptoms are associated with impairment in executive functions. However, previous studies have not differentiated between 'cold' and 'hot' executive functions. We hypothesized that the propensity for psychotic symptoms is specifically associated with impairment in 'hot' executive functions, such as decision-making in the context of uncertain rewards and losses. In a cohort of 156 youth (mean age 12.5, range 7-24 years) enriched for familial risk of SMI, we measured cold and hot executive functions with the spatial working memory (SWM) task (total errors) and the Cambridge Gambling Task (decision-making), respectively. We assessed psychotic symptoms using the semi-structured Kiddie Schedule for Affective Disorders and Schizophrenia interview, Structured Interview for Prodromal Syndromes, Funny Feelings, and Schizophrenia Proneness Instrument - Child and Youth version. In total 69 (44.23%) youth reported psychotic symptoms on one or more assessments. Cold executive functioning, indexed with SWM errors, was not significantly related to psychotic symptoms [odds ratio (OR) 1.36, 95% confidence interval (CI) 0.85-2.17, p = 0.204). Poor hot executive functioning, indexed as decision-making score, was associated with psychotic symptoms after adjustment for age, sex and familial clustering (OR 2.37, 95% CI 1.25-4.50, p = 0.008). The association between worse hot executive functions and psychotic symptoms remained significant in sensitivity analyses controlling for general cognitive ability and cold executive functions. Impaired hot executive functions may be an indicator of risk and a target for pre-emptive early interventions in youth.

Social anxiety commonly occurs across the course of schizophrenia, including in the premorbid and prodromal phases of psychotic disorders. Some have posited that social anxiety may exist on a continuum with paranoia; however, empirical data are lacking. The study aim was to determine whether attenuated positive psychotic symptoms are related to social anxiety. Young adults (N=1378) were administered the Prodromal Questionnaire (PQ), which measures attenuated positive psychotic symptoms (APPS), and the Social Phobia Scale (SPS), which measures a subset of social anxiety symptoms. Confirmatory factor analyses were conducted to address the extent to which social anxiety and APPS tap distinct dimensions. Confirmatory factor analyses support the existence of a separate social anxiety factor scale and four separate, though interrelated, APPS factor domains (unusual thought content, paranoia/suspiciousness, disorganized thinking, and perceptual abnormalities). Additionally, social anxiety was significantly, but not differently related to each APPS domain, although the magnitude was reduced between social anxiety and distressing APPS. The current study suggests that social anxiety and attenuated positive psychotic symptoms are separable constructs, but are significantly associated with each other.

PANSS, SIS-R and CAPE scales were used to assess positive psychotic symptoms. Four WAIS III subtests were used to assess IQ.A total of 61 FEP, 26 BPD and 150 controls were evaluated. 29 FEP were revaluated after one year. 44% of FEP (OR = 8.4, 95% CI: 3.9-17.9 displayed a JTC reasoning bias versus 19% of BPD (OR = 2.5, 95% CI: 0.8-7.8 and 9% of controls. JTC was not associated with level of psychotic symptoms or specifically delusionality across the different groups. Differences between FEP and controls were independent of sex, educational level, cannabis use and IQ. After one year, 47.8% of FEP with JTC at baseline again displayed JTC.JTC in part reflects trait vulnerability to develop disorders with expression of psychotic symptoms.

Previous studies have addressed the prominence of psychotic symptoms in conjunction with multiple personality disorder (now dissociative identity disorder). The present study examines the relation between psychotic symptoms and a more pervasive form of dissociative disturbance, namely dissociative detachment. Two hundred sixty-six women in inpatient treatment for severe trauma-related disorders completed the Dissociative Experiences Scale (DES), and 102 of these patients also completed the Millon Clinical Multiaxial Inventory (MCMI-III). A factor analysis of the DES yielded two dimensions of dissociative detachment: detachment from one's own actions and detachment from the self and the environment. Each of these DES dimensions relates strongly to the thought disorder and schizotypal personality disorder scales of the MCMI-III. We propose that severe dissociative detachment, by virtue of loosening the moorings in inner and outer reality, is conducive to psychotic symptoms and personality decompensation.
Posttraumatic stress disorder (PTSD) is a condition being increasingly recognized. The diagnosis is based on the re-experiencing of a traumatic event. There have been reports of the presence of psychotic symptoms in some cases of PTSD. This may represent increased severity or a different diagnostic clinical entity.

The co-occurrence between post-traumatic symptoms and psychotic symptoms is well described in the immediate suites of a trauma but can also be chronic. This symptomatic co-occurrence, rarely studied in the literature, is often approached under the sole angle of a primary post-traumatic stress disorder (PTSD) or of a primary psychosis, without federative will to unify the psychotic and post-traumatic symptoms within the same nosological framework. Individuals with schizophrenia or schizoaffective disorder report higher rates of trauma and assault than the general population. High rates of PTSD have been noted in severe mental illness cohorts. Psychotic phenomena may be a relatively common manifestation in patients with chronic PTSD. The purpose of this paper is to expose the various theorical psychopathological aspects between the symptoms of psychosis and PTSD. In populations of veterans, positive and negative symptoms of psychosis in PTSD are described as delusional thoughts and hallucinations often combat-specific. When a PTSD becomes established at a subject to the personality of neurotic structure, the intensity of the PTSD's symptoms lead to a psychotic expression which constitutes a factor of seriousness. Besides, PTSD often induces a risk of substance use disorder supplying psychotic symptoms. Cannabis increases the hallucinations, cocaine strengthens an underlying paranoid tone, and alcohol implies withdrawal hallucinosis. Moreover, such consumption could be a risk factor for the future development of chronic psychosis. From another point of view, by basing themselves on the plasma dopamine beta-hydroxylase activity, some authors made the analogy between psychotic major depression and PTSD with psychotic features (also characterized as a distinct psychotic subtype of PTSD). However, other studies found no correlation between PTSD with psychotic features and family predisposition for schizophrenia or schizoaffective disorder. The determination of the

Co-morbidity with cannabis use disorder is common in patients with a psychotic disorder and is associated with adverse outcome. This study aimed to determine prevalence of cannabis use disorder among patients with a psychotic disorder and subjects at ultra high risk of psychosis and to study the influence of cannabis use on severity of (pre-)psychotic symptomatology, psychosocial functioning and variables related to the course of the disorder in these patients. In this study 169 consecutively assessed patients with a psychotic disorder were included as well as 59 consecutively assessed subjects at ultra high risk of psychosis. 45% of the patients with a psychotic disorder and 27% of the UHR patients were diagnosed with a co-morbid cannabis use disorder. Patients with cannabis use disorders did not differ from patients without cannabis use disorder in severity of psychotic symptoms. However, excluding patients with substance use disorder other than cannabis use disorder resulted in higher scores on positive symptom levels for patients with cannabis use disorder compared to patients without any substance use disorder. Regarding ultra high risk patients, subjects with cannabis use disorder did not differ from subjects without cannabis use disorder on severity of pre-psychotic symptomatology. However, a negative correlation was found between the amount of cannabis used recently and scores on the pre-psychotic negative subscale. Our results suggest a specific association between cannabis abuse and psychotic symptomatology.

Several research groups have shown that people with schizophrenia who offend do not form a homogenous group. A three-group model claimed by Hodgins proposes distinguishing between people who start offending before the onset of psychosis (early starters), after psychosis onset but at age 34 years or under (late starters) and after psychosis onset but at age 35 years or older (late first offenders). This study aimed to test the hypotheses (1) that the personality of early starters and non-psychotic offenders would be similar, but different from either late-starter group; (2) that the late-starter groups would be more likely to have positive psychotic symptoms than non-criminal patients with schizophrenia; and (3) that symptom types would differentiate the psychotic groups. A retrospective file study was conducted on cases of 97 early starters, 100 late starters and 26 late first offenders all drawn from the Netherlands Institute of Forensic Psychiatry and Psychology (NIFP) archives 1993-2008, 115 non-psychotic offenders from 2005-2008 NIFP archives and 129 patients with schizophrenia and no criminal history from one general service in Rotterdam. Early starters closely resembled the non-psychotic offenders in their premorbid anti-social personality characteristics. The two late-onset offending psychosis groups were more likely to have persecutory and/or grandiose delusions than non-offenders with psychosis, but so were the early starters. In a first study to compare subgroups of offenders with psychosis directly with non-psychotic offenders and non-offenders with psychosis, we found such additional support for a distinction between early and late starters with psychosis that different treatment strategies would seem indicated, focusing on personality and substance misuse for the former but psychotic symptoms for all. It remains to be seen whether the higher rate of alcohol misuse amongst late first offenders is a fundamental distinction or a function of age

Full Text Available Benzydamine hydrochloride is a locally acting nonsteroidal anti-inflammatory drug. Benzydamine hydrochloride overdose can cause stimulation of central nervous system, hallucinations, and psychosis. We presented a young man with psychotic symptoms due to benzydamine hydrochloride abuse. He received a total dose of 1000 mg benzydamine hydrochloride with alcohol for its hallucinative effects. Misuse of benzydamine hydrochloride must be considered in differential diagnosis of first-episode psychosis and physicians should consider possibility of abuse in prescribing.

Cocaine use is significantly associated with psychiatric co-morbidities of which psychotic symptoms are the most typical. The primary goal of this study is to estimate the life-time prevalence of cocaine-induced psychotic symptoms (CIPS) in a sample of patients without a history of primary psychosis, who attended specific out-patient drug-dependence treatment centres (ODDTCs). This is an observational, cross-sectional design and a consecutive sampling technique. The Scale for Assessment of Positive Symptoms-Cocaine Induced Psychosis (SAPS-CIP) was used to interview 114 patients who request treatment at specific ODDTCs for problems related to cocaine use. Most patients, 89.5% (95% CIs: 83.8-95.2%) had dependence of cocaine and 84.2% (95% CIs: 77.5-90.9%) showed at least one CIPS. Patients with CIPS had used cocaine more times throughout their lives and had a more frequency of use during the period of higher abuse severity in the last year, had higher severity of dependence score and had fewer abstinence periods greater than 30 days compared with those without CIPS. Cocaine dependency severity scale scores were significantly greater in patients with CIPS compared with those without CIPS. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Stimulants, such as methylphenidate, are among the most commonly used medications in children and adolescents. Psychotic symptoms have been reported as rare adverse reactions to stimulants but have not been systematically inquired about in most previous studies. Family history of mental illness may increase the vulnerability to drug-induced psychotic symptoms. We examined the association between stimulant use and psychotic symptoms in sons and daughters of parents with major mood and psychotic disorders. We assessed psychotic symptoms, psychotic-like experiences, and basic symptoms in 141 children and youth (mean ± SD age: 11.8 ± 4.0 years; range: 6-21 years), who had 1 or both parents with major depressive disorder, bipolar disorder, or schizophrenia, and of whom 24 (17.0%) had taken stimulant medication. Psychotic symptoms were present in 62.5% of youth who had taken stimulants compared with 27.4% of participants who had never taken stimulants. The association between stimulant use and psychotic experiences remained significant after adjustment for potential confounders (odds ratio: 4.41; 95% confidence interval: 1.82-10.69; P = .001) and was driven by hallucinations occurring during the use of stimulant medication. A temporal relationship between use of stimulants and psychotic symptoms was supported by an association between current stimulant use and current psychotic symptoms and co-occurrence in cases that were assessed on and off stimulants. Psychotic symptoms should be monitored during the use of stimulants in children and adolescents. Family history of mood and psychotic disorders may need to be taken into account when considering the prescription of stimulants. Copyright © 2016 by the American Academy of Pediatrics.

Psychotic symptoms are common among cocaine users. An observational naturalistic study on the effects and events of intravenous cocaine use in a drug consumption room was carried out; the patients were diagnosed of cocaine dependence (according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision). Twenty-one patients, 81% men self-injected cocaine 375 times. Psychotic symptoms were observed in 62% of the patients and 21% of the self-injections; delusions were observed in 9.3%, psychotic self-reference with insight in 9.1%, illusions in 6.4%, and hallucinations in 5.3%. A higher presence of psychotic symptoms was noted with cannabis used in the previous month (76.9% versus 44.4%; P = .001) (no psychotic symptoms group); also, a greater use of benzodiazepines was observed: 75.6% versus 63.6% (P = .046). Lower use of methadone in the group with psychosis was observed: 75.6% versus 97.3% (P = .001). Motor alterations were tremor 58%, stereotyped movements 24%, and behaviour alteration 6%, significantly more frequent in the psychotic group. Thus, there was a high frequency of psychotic symptoms after intravenous cocaine use; patients with psychotic symptoms reported higher use of cannabis and benzodiazepines in the previous month and lower use of methadone. More tremors and stereotyped movements were observed in the group with psychotic symptoms. It is necessary to give a special approach to cocaine intravenous users.

Cannabidiol is a component of marijuana that does not activate cannabinoid receptors, but moderately inhibits the degradation of the endocannabinoid anandamide. We previously reported that an elevation of anandamide levels in cerebrospinal fluid inversely correlated to psychotic symptoms. Furthermore, enhanced anandamide signaling let to a lower transition rate from initial prodromal states into frank psychosis as well as postponed transition. In our translational approach, we performed a double-blind, randomized clinical trial of cannabidiol vs amisulpride, a potent antipsychotic, in acute schizophrenia to evaluate the clinical relevance of our initial findings. Either treatment was safe and led to significant clinical improvement, but cannabidiol displayed a markedly superior side-effect profile. Moreover, cannabidiol treatment was accompanied by a significant increase in serum anandamide levels, which was significantly associated with clinical improvement. The results suggest that inhibition of anandamide deactivation may contribute to the antipsychotic effects of cannabidiol potentially representing a completely new mechanism in the treatment of schizophrenia.

Full Text Available This study aimed to determine the prevalence of psychotic symptoms in urban Tanzania and their relationship with demographic, socio-economic and social factors. A random sample of 899 adults aged 15–59 was surveyed. The main outcome measure was endorsement of one or more psychotic symptoms identified by the Psychosis Screening Questionnaire. 3.9% respondents reported one or more psychotic symptoms in the preceding year. Significantly higher rates of symptoms were found in those who had recently experienced two or more stressful life events, those with CMD and people who had used cannabis in the preceding year.
Psychotic symptoms occur more frequently in the general population than psychotic disorder and index risk for psychopathology. Multiple studies have reported on the prevalence of these symptoms using self-report questionnaires or clinical interviews but there is a lack of consensus about the prevalence of psychotic symptoms among children and adolescents.

Adverse effects of maternal substance use during pregnancy on fetal development may increase risk of psychopathology. To examine whether maternal use of tobacco, cannabis or alcohol during pregnancy increases risk of offspring psychotic symptoms. A longitudinal study of 6356 adolescents, age 12, who completed a semi-structured interview for psychotic symptoms in the Avon Longitudinal Study of Parents and Children (ALSPAC) birth cohort. Frequency of maternal tobacco use during pregnancy was associated with increased risk of suspected or definite psychotic symptoms (adjusted odds ratio 1.20, 95% CI 1.05-1.37, P = 0.007). Maternal alcohol use showed a non-linear association with psychotic symptoms, with this effect almost exclusively in the offspring of women drinking >21 units weekly. Maternal cannabis use was not associated with psychotic symptoms. Results for paternal smoking during pregnancy and maternal smoking post-pregnancy lend some support for a causal effect of tobacco exposure in utero on development of psychotic experiences. These findings indicate that risk factors for development of non-clinical psychotic experiences may operate during early development. Future studies of how in utero exposure to tobacco affects cerebral development and function may lead to increased understanding of the pathogenesis of psychotic phenomena.

Individuals with psychotic symptoms may actually correspond to various subgroups, characterized by different patterns of psychotic symptoms as well as specific sociodemographic and clinical correlates. We aimed to identify groups of individuals from the general population with specific patterns of psychotic symptoms. In a 38,694-subject survey, a latent class analysis was performed to identify subgroups based on the distribution of seven psychotic symptoms taken from the Mini International Neuropsychiatric Interview. The different classes were subsequently compared according to sociodemographic and clinical correlates. The best fit was obtained with a four-class solution, including the following: (1) a class with a low prevalence of all psychotic symptoms ('LOW', 85.9%); (2) a class with a high prevalence of all psychotic symptoms ('HAL + DEL', 1.7%); and classes with a high prevalence of (3) hallucinations ('HAL', 4.5%) or (4) delusions ('DEL', 7.9%). The HAL + DEL class displayed higher rates of history of trauma, social deprivation and migrant status, while the HAL and DEL classes displayed intermediate rates between HAL + DEL and LOW. HAL + DEL displayed the highest rates of psychotic and non-psychotic disorders and the use of mental health treatment, while HAL and DEL displayed intermediate rates of these disorders between HAL + DEL and LOW. In comparison to the HAL class, psychotic and substance use disorders were more frequent in the DEL class, while anxiety and mood disorders were less frequent. These findings support the hypothesis of a continuum model relating the level of psychotic symptoms to the level of global psychopathology.

Cocaine use is associated with the occurrence of transient psychotic symptoms. Sixteen poly-substance abusers already in treatment, who were diagnosed with crack dependence, were assessed twice: at baseline and after 3 weeks of medical management specifically aimed at cocaine abstinence. The psychotic symptoms were assessed with the French version of the Scale for Assessment of Positive Symptoms-Cocaine-Induced Psychosis (SAPS-CIP). There was a decrease of both cocaine intake and psychotic symptoms at week 3 (Wilcoxon's Z, p < .001 and .028, respectively). Furthermore, there was a significant correlation between psychotic symptoms and dose reduction (r(2) = .49, Spearman's ρ= .613, p < .012). Copyright © American Academy of Addiction Psychiatry.
Full Text Available Various psychotic disorders develop often at different stages of the disease. A comprehensive approach of type, frequency and clinical aspects of the psychotic disorders patients with Alzheimer’s disease (AD can optimize management of these conditions in patients with dementia. We examined 120 patients with probable AD. The routine clinical examination and observation were used to delineate the most common psychotic symptoms. Delusions, found in the explored patients were predominantly paranoid. The delusions are often short lived and lack complexity of that seen in schizophrenia. In number of cases they are difficult to be distinguished from confabulations. Hallucinations were mostly verbal, visual and tactile. Misidentification syndromes were identified in a considerable number of patients. They are often disputable or have been classified as delusions or hallucinations, depending on interpretation of psychotic phenomena. We discuss different forms of misidentification. The presence of psychotic symptoms predicts the occurrence and frequency of different forms of aggression and destructive behavior.

In the field of dual diagnosis, physicians are frequently presented with pharmacological questions. Questions about the risk of developing psychotic symptoms in cocaine users who need treatment with dopaminergic drugs could lead to an undertreatment. Review the presence of psychotic symptoms in patients with cocaine abuse/dependence, in treatment with dopaminergic drugs. Systematic PubMed searches were conducted including December 2014, using the keywords: "cocaine", dopaminergic drug ("disulfuram-methylphenidate-bupropion-bromocriptine-sibutramineapomorphine- caffeine") and ("psychosis-psychotic symptoms-delusional-paranoia"). Articles in English, Spanish, Portuguese, French, and Italian were included. Articles in which there was no history of cocaine abuse/dependence, absence of psychotic symptoms, systematic reviews, and animal studies, were excluded. 313 papers were reviewed. 7 articles fulfilled the inclusion-exclusion criteria. There is a clinical trial including 8 cocaine-dependent patients using disulfiram in which 3 of them presented psychotic symptoms and 6 case-reports: disulfuram (1), methylphenidate (1), disulfiram with methylphenidate (2), and bupropion (2), reporting psychotic symptoms, especially delusions of reference and persecutory ideation. Few cases have been described, which suggests that the appearance of these symptoms is infrequent. The synergy of dopaminergic effects or the dopaminergic sensitization in chronic consumption are the explanatory theories proposed by the authors. In these cases, a relationship was found between taking these drugs and the appearance of psychotic symptoms. Given the low number of studies found, further research is required. The risk of psychotic symptoms seems to be acceptable if we compare it with the benefits for the patients but a closer monitoring seems to be advisable.

Full Text Available There have been few epidemiological surveys to establish prevalence and associated risk factors of psychosis in Sub-Saharan Africa. This paper reports a population- based epidemiological survey in rural Kenya of the prevalence of psychotic symptoms and their relationship with demographic, socio-economic and other risk factors. A random sample of 2% of all adults living in Maseno, Kisumu District of Nyanza province, Kenya (50,000 population were studied, aiming for a sample size of 1,000 people. The psychosis screening questionnaire was used to assess the prevalence of psychotic symptoms in the preceding twelve months. The response rate was 87.6%. The prevalence of single psychotic symptoms in rural Kenya was 8% of the adult population, but only 0.6% had two symptoms and none had three or more psychotic symptoms in this sample size. Psychotic symptoms were evenly distributed across this relatively poor rural population and were significantly associated with presence of common mental disorders, and to a lesser extent with poor physical health and housing type. We conclude that single psychotic symptoms are relatively common in rural Kenya and rates are elevated in those with CMD, poor physical health and poor housing.

Little is known about motives or expectancies for cannabis use in psychotic populations, despite these cognitive factors being a central focus of the treatment for substance misuse in psychosis. This study examined the relationship between cannabis use expectancies, cannabis use and psychotic symptoms among cannabis using psychotic inpatients. A secondary aim was to determine if there were significant differences in the cannabis use expectancies of psychotic patients with and without Diagnostic and Statistical Manual version IV (DSM-IV) cannabis dependence. Participants consisted of 101 in-patients with psychosis who had used cannabis more than five times in the past year. Expectancies were assessed using the Cannabis Expectancy Questionnaire (CEQ). The frequency of cannabis use, severity of cannabis dependence, presence of DSM-IV cannabis dependence and severity of psychotic symptoms were also assessed using standardised measures. Results suggested that cannabis use expectancies were associated with cannabis use but not symptom variables. Expectancies for cannabis use predicted recent cannabis use and the presence and severity of cannabis dependence. Psychotic patients with DSM-IV cannabis dependence had significantly higher expectancies for negative effects from cannabis use. Prospective research examining the influence of motives and expectancies for cannabis use on cannabis use and psychotic symptoms is required to obtain a greater understanding of substance use in psychosis and assist with the development of innovative treatment interventions.

To carryout factor analysis of symptom profile of patients with schizophrenia assessed by using positive and negative syndrome scale (PANSS), Calgary depression rating scale (CDSS), Young mania rating scale (YMRS) and YBOCS checklist. 181 patients of schizophrenia were assessed on PANSS, CDSS, YMRS and YBOCS checklist. Factor analysis of PANSS yielded 3 factor structure (positive, negative, anxiety). When the items of CDSS were added to the PANSS items, total number of factors increased to 4 with depression emerging as a separate factor. Addition of YMRS to PANSS and CDSS led to emergence of 5 factor model. Further addition of YBOCS checklist led to emergence of a 7 factor model (positive, depressive, obsessive compulsive, negative, manic, anxiety and obsessive compulsive-2), which explained 49.85% variance of the data. Positive symptoms emerged as the factor-1. Depressive symptoms loaded on the factor-2, negative symptoms loaded on to factor-4, manic symptoms loaded onto factor-5 and anxiety symptoms loaded onto factor-6. OC symptoms loaded onto factor 3 and 7. Present study suggests that when multiple scales are used for assessment of various symptoms of schizophrenia, the symptoms separate out into 7 factors. This finding suggests that clinical assessment of schizophrenia should not be limited to core psychotic symptoms only and structured instruments must be used to elicit other symptoms too while monitoring the clinical picture of patients with schizophrenia.

Full Text Available Previous magnetic resonance imaging (MRI research suggests that, prior to the onset of psychosis, high risk youths already exhibit brain abnormalities similar to those present in patients with schizophrenia.The goal of the present study was to describe the functional organization of endogenous activation in young adolescents who report auditory verbal hallucinations (AVH in view of the "distributed network" hypothesis of psychosis. We recruited 20 young people aged 13-16 years who reported AVHs and 20 healthy controls matched for age, gender and handedness from local schools.Each participant underwent a semi-structured clinical interview and a resting state (RS neuroimaging protocol. We explored functional connectivity (FC involving three different networks: 1 default mode network (DMN 2 salience network (SN and 3 central executive network (CEN. In line with previous findings on the role of the auditory cortex in AVHs as reported by young adolescents, we also investigated FC anomalies involving both the primary and secondary auditory cortices (A1 and A2, respectively. Further, we explored between-group inter-hemispheric FC differences (laterality for both A1 and A2. Compared to the healthy control group, the AVH group exhibited FC differences in all three networks investigated. Moreover, FC anomalies were found in a neural network including both A1 and A2. The laterality analysis revealed no between-group, inter-hemispheric differences.The present study suggests that young adolescents with subclinical psychotic symptoms exhibit functional connectivity anomalies directly and indirectly involving the DMN, SN, CEN and also a neural network including both primary and secondary auditory cortical regions.

The current study tests whether perceptions of defeat and entrapment are the psychological mechanisms underlying the link between positive psychotic symptoms and suicidal ideation in schizophrenia. A sample of 78 patients with schizophrenia spectrum disorders completed self-report measures and a clinical interview. Of this sample, 21.8% reported a single past suicide attempt and 50% reported multiple past attempts. It was found that perceptions of defeat and entrapment, conceptualised as a single variable, accounted for a large proportion (31%) of the variance in suicidal ideation and behaviour. Defeat and entrapment also mediated the relationship between positive symptom severity and suicidal ideation. This result held whilst controlling for levels of hopelessness and depression. Secondary analyses suggested that suspiciousness in particular was linked to suicidal ideation. The results support a socio-cognitive model (The Schematic Appraisals Model of Suicide: SAMS) of suicide in psychosis. Copyright 2009 Elsevier Ltd. All rights reserved.

Full Text Available Huntington's disease is an autosomal dominant neurodegenerative disease. The disease begins between the ages of 30-50, including motor symptoms, psychiatric symptoms and is characterized by progressive dementia. Common psychiatric disorders of Huntington’s disease include mood and anxiety disorders, behavior and personality changes. Psychosis is relatively rare. Here, a patient is present, who has Huntington’s disease, which is associated with psychotic symptoms. 61-year-old male patient who were followed for Huntington disease for 25 years was admitted for complaints of thinking of poisoning and refuse to eat something. Patient was started on olanzapine at dose of 5 mg/day. In follow up psychotic symptoms disappeared. Emerging psychotic symptoms in Huntington disease is created a need for antipsychotic treatment. Atypical antipsychotic agents should be preferred in the treatment and as in the case olanzapine may be used as a treatment option should be kept in mind to control both involuntary movements and psychotic symptoms in Huntington's disease with psychotic features.

We examined the lifetime experience of hallucinations and delusions associated with transient methamphetamine-related psychosis (MAP), persistent MAP and primary psychosis among a cohort of dependent methamphetamine users. Participants were classified as having (a) no current psychotic symptoms, (n=110); (b) psychotic symptoms only when using methamphetamine (transient MAP, n=85); (c) psychotic symptoms both when using methamphetamine and when abstaining from methamphetamine (persistent MAP, n=37), or (d) meeting DSM-IV criteria for lifetime schizophrenia or mania (primary psychosis, n=52). Current psychotic symptoms were classified as a score of 4 or more on any of the Brief Psychiatric Rating Scale items of suspiciousness, hallucinations or unusual thought content in the past month. Lifetime psychotic diagnoses and symptoms were assessed using the Composite International Diagnostic Interview. Transient MAP was associated with persecutory delusions and tactile hallucinations (compared to the no symptom group). Persistent MAP was additionally associated with delusions of reference, thought interference and complex auditory, visual, olfactory and tactile hallucinations, while primary psychosis was also associated with delusions of thought projection, erotomania and passivity. The presence of non-persecutory delusions and hallucinations across various modalities is a marker for persistent MAP or primary psychosis in people who use methamphetamine. Copyright © 2017.

Cannabis use has been associated with a continuum of psychotic experiences. However, it is unclear whether mood and anxiety symptoms account for increases in attenuated positive psychotic symptoms (APPS) among cannabis users. We predicted that depression and anxiety symptoms would mediate the relation between cannabis use and APPS, and between cannabis use and endorsement of eight or more distressing APPS (D-APPS), a potentially more clinically meaningful group. Young adults (n=674) completed the Prodromal Questionnaire (PQ); Drug Use Frequency measure; Center for Epidemiologic Studies Depression Scale; State-Trait Anxiety Inventory, Trait Form, Anxiety Subscale; and Social Phobia Scale. Results indicated that symptoms of trait anxiety, but not symptoms of depression or social anxiety, mediated the relationship between cannabis use and APPS, as well as the relationship between cannabis use and D-APPS. Results indicate that symptoms of trait anxiety may play a role in the relation between cannabis use and APPS. Findings underscore the importance of considering clinical characteristics co-occurring with psychotic symptoms, such as affective symptoms, when examining the association between cannabis use and psychotic symptoms.

This paper focuses on the role of adoption and family relations as moderators of genetic risk for psychotic disorders. Participants included 184 adolescents in the Republic of Palau identified to be at genetic risk for schizophrenia and other psychotic disorders. Palau is an island nation in Micronesia with a lifetime prevalence of 1.99% for schizophrenia and 2.67% for psychotic disorders more broadly defined. In Palauan culture, kinship adoption is a common cultural practice; 47 of the 184 participants had been adopted at an early age. The current study was designed to test the hypothesis that adoption would function as a protective factor among Palauan youth at genetic risk for the development of psychotic symptoms. Participants were evaluated for psychotic and other psychiatric symptoms using KSADS-PL. Concurrently, the Youth Self Report was used to assess the perceived quality of family relationships. Results indicated that adopted adolescents were more likely to develop psychotic symptoms than non-adopted adolescents. However, perceived family relations moderated the association between adoption status and psychotic symptoms, such that adopted adolescents with poorer family relations reported disproportionately higher rates of psychotic symptoms. Family relations also moderated the association between level of genetic risk and psychotic symptoms, independently of adoption status. Consistent with previous research, adolescents at high genetic risk who reported more positive family relations also reported fewer psychotic symptoms.

The primary objective of this study was to compare and contrast psychotic symptoms reported by cocaine- and methamphetamine-dependent individuals. Participants included 27 cocaine-dependent and 25 methamphetamine-dependent males, as well as 15 cocaine-dependent and 18 methamphetamine-dependent females. After screening, participants were excluded if they met criteria for any Axis I diagnosis other than nicotine dependence, or methamphetamine or cocaine dependence (ie, participants had to use either methamphetamine or cocaine but were excluded if they met dependence criteria for both). The participants were administered the newly developed Psychotic Symptom Assessment Scale (PSAS), which assesses psychotic symptoms. A high proportion of both cocaine- and methamphetamine-dependent men and women reported delusions of paranoia and auditory hallucinations. However, during the abstinent and intoxicated conditions, methamphetamine-dependent men and women were more likely than cocaine-dependent men and women to report psychotic symptoms. Future studies will compare psychotic symptoms reported by non-dependent recreational stimulant users to stimulant-dependent individuals.

This review focuses on the differentiation of schizophrenia in the setting of adult psychiatry from neurodevelopmental disorders (NDD's) and psychosis due to other medical conditions (PDMC). Psychotic disorders in early adulthood are most frequently diagnosed with the schizophrenia spectrum or mood disorders. However, they may be the manifestation of neurologic, endocrine or immunologic disease. Individuals with NDD's such as the autism spectrum disorder (ASD) or intellectual developmental disorder (IDD) may also present initially in adulthood. Therefore it is not uncommon that the psychiatrist is the first physician to assess a psychotic patient with underlying medical illness or a NDD. Failure to identify the underlying cause will delay appropriate management. Overdiagnosis of primary psychiatric disorders may be misleading in planning the treatment, as evidence-based treatment algorithms relevant to psychosis are intended for primary psychotic disorders like schizophrenia, and symptomatic treatment may result in unnecessary exposure to antipsychotic drugs. Exclusion of other medical conditions and NDD's is essential before establishing a diagnosis of schizophrenia.

To assess the prevalence of sleep problems and their association with psychotic symptoms using a global database. Community-based cross-sectional study. Data were analyzed from the World Health Organization's World Health Survey (WHS), a population-based survey conducted in 70 countries between 2002 and 2004. 261,547 individuals aged ≥ 18 years from 56 countries. N/A. The presence of psychotic symptoms in the past 12 months was established using 4 questions pertaining to positive symptoms from the psychosis screening module of the Composite International Diagnostic Interview. Sleep problems referred to severe or extreme sleep problems in the past 30 days. Multivariable logistic regression was used to estimate the associations. The overall prevalence of sleep problems was 7.6% and ranged from 1.6% (China) to 18.6% (Morocco). Sleep problems were associated with significantly higher odds for at least one psychotic symptom in the vast majority of countries. In the pooled sample, after adjusting for demographic factors, alcohol consumption, smoking, and chronic medical conditions, having sleep problems resulted in an odds ratio (OR) for at least one psychotic symptom of 2.41 (95% confidence interval [CI] 2.18-2.65). This OR was 1.59 (1.40-1.81) when further adjusted for anxiety and depression. A strong association between sleep problems and psychotic symptoms was observed globally. These results have clinical implications and serve as a basis for future studies to elucidate the causal association between psychotic symptoms and sleep problems. © 2015 Associated Professional Sleep Societies, LLC.

Psychotic symptoms (delusions and hallucinations) are reported to be increased among persons using illicit substances, but little is known about the comparative frequency with which the symptoms occur with abuse of different substances. To establish this, we interviewed individuals who had wide experience of commonly used drugs. Four hundred seventy-six intravenous drug users, crack-cocaine users, and heroin snorters recruited via street outreach were interviewed using the Composite International Diagnostic Interview-Substance Abuse Model to assess dependence on a number of substances including amphetamines, cannabis, cocaine, and opioids. As a part of this assessment, we assessed a history of delusions and hallucinations in the context of use of, or withdrawal from, these specific substances. From 27.8% to 79.6% users of amphetamine, cannabis, cocaine, and opiates met Diagnostic and Statistical Manual of Mental Disorders, Third Edition, Revised, dependence for that specific substance. The prevalence of psychotic symptoms associated with each specific substance ranged from users with no diagnosis to users with severe dependence as follows: amphetamines (5.2%-100%), cannabis (12.4%-80.0%), cocaine (6.7%-80.7%), and opiates (6.7%-58.2%). The risk of psychotic symptoms increased for respondents who abused (odds ratio [OR], 12.2) or had mild (OR, 17.1), moderate (OR, 47.0), or severe dependence (OR, 114.0) on cocaine when compared to those who were users with no diagnosis. A similar pattern was evident in cannabis, opiate, and amphetamine users. Most users dependent on illicit substances experience psychotic symptoms in the context of use of, or withdrawal from, these substances. Psychotic symptoms increased with the severity of the substance use disorders for all 4 substances. These findings emphasize the importance of developing services to target this population as they are at a heightened risk for developing psychotic symptoms.

Cocaine-induced psychosis (CIP) is among the most serious adverse effects of cocaine. Reduced serum brain-derived neurotrophic factor (BDNF) levels have been reported in schizophrenia and psychosis; however, studies assessing the involvement of BDNF in CIP are lacking. A total of 22 cocaine-dependent patients (aged 33.65 ± 6.85) who had never experienced psychotic symptoms under the influence of cocaine (non-CIP) and 18 patients (aged 34.18 ± 8.54) with a history of CIP completed a 2-week detoxification program in an inpatient facility. Two serum samples were collected from each patient at baseline and at the end of the protocol. Demographic, consumption and clinical data were recorded for all patients. A paired group of healthy controls was also included. At the beginning of the detoxification treatment, serum BDNF levels were similar in both the non-CIP and the CIP groups. During early abstinence, the non-CIP group exhibited a significant increase in serum BDNF levels (p = 0.030), whereas the CIP group exhibited a decrease. Improvements in depression (Beck Depression Inventory, BDI, p = 0.003) and withdrawal symptoms (Cocaine Selective Severity Assessment, CSSA, p = 0.013) show a significant positive correlation with serum BDNF levels in the non-CIP group, whereas no correlation between the same variables was found in the CIP group. This study suggests that BDNF plays a role in the transient psychotic symptoms associated with cocaine consumption. In the non-CIP group, the increase in serum BDNF appears to be driven by the effects of chronic cocaine consumption and withdrawal. In contrast, patients with CIP share some of the neurotrophic deficiencies that characterize schizophrenia and psychosis. Copyright © 2013 S. Karger AG, Basel.

A personal history of childhood trauma has been associated with the severity of psychotic symptoms in several disorders. We evaluated retrospectively cocaine-induced psychotic symptoms with the SAPS-CIP and childhood trauma with the CTQ in a clinical sample of 144 cocaine users. The SAPS-CIP score was not statistically associated with the presence or number or intensity of trauma, but was associated with rapid routes of administration (intravenous and smoked) and with frequent cocaine use.

The psychostimulant drugs cocaine and methamphetamine are potent indirect dopamine receptor agonists which act through similar but not identical mechanisms. Studies in humans have observed that a large proportion of those who chronically use these drugs experience psychotic symptoms. However, direct comparisons of psychotic symptom severity between cocaine and methamphetamine users are lacking. The goal of the present study was to directly compare severity of psychotic symptoms between cocaine- and methamphetamine-dependent individuals. Additionally, we sought to determine how concurrent cocaine + methamphetamine dependence would influence psychotic symptoms. We recruited 153 polysubstance-using subjects meeting DSM-IV-TR criteria for cocaine dependence, 38 with methamphetamine dependence, and 32 with cocaine + methamphetamine dependence. Psychotic symptoms were assessed with the Positive and Negative Syndrome Scale (PANSS) and analyzed using a five-factor model. All participants were also assessed for physical and mental illnesses as well as recent substance use. Most subjects completed a comprehensive neurocognitive battery. While all three groups exhibited high total PANSS scores, the positive symptom subscale was significantly higher in the methamphetamine-dependent (17.03 ± 6.3) than the cocaine-dependent group (13.51 ± 4.12) and non-significantly higher (p = 0.08) than the cocaine + methamphetamine group (14.44 ± 5.50). Groups also differed on demographic variables, viral infection, and other indices of substance use, which were unlikely to account for the difference in positive symptoms. There were only modest differences between groups in neurocognitive function. Methamphetamine dependence was associated with more severe positive symptoms of psychosis than cocaine dependence. Concurrent cocaine + methamphetamine dependence did not increase psychosis severity.

Psychotic disorders and major depression, both typically adult-onset conditions, often co-occur. At younger ages psychotic experiences and depressive symptoms are often reported in the community. We used a genetically sensitive longitudinal design to investigate the relationship between psychotic experiences and depressive symptoms in adolescence. A representative community sample of twins from England and Wales was employed. Self-rated depressive symptoms, paranoia, hallucinations, cognitive disorganization, grandiosity, anhedonia, and parent-rated negative symptoms were collected when the twins were age 16 (N = 9618) and again on a representative subsample 9 months later (N = 2873). Direction and aetiology of associations were assessed using genetically informative cross-lagged models. Depressive symptoms were moderately correlated with paranoia, hallucinations, and cognitive disorganization. Lower correlations were observed between depression and anhedonia, and depression and parent-rated negative symptoms. Nonsignificant correlations were observed between depression and grandiosity. Largely the same genetic effects influenced depression and paranoia, depression and hallucinations, and depression and cognitive disorganization. Modest overlap in environmental influences also played a role in the associations. Significant bi-directional longitudinal associations were observed between depression and paranoia. Hallucinations and cognitive disorganization during adolescence were found to impact later depression, even after controlling for earlier levels of depression. Our study shows that psychotic experiences and depression, as traits in the community, have a high genetic overlap in mid-adolescence. Future research should test the prediction stemming from our longitudinal results, namely that reducing or ameliorating positive and cognitive psychotic experiences in adolescence would decrease later depressive symptoms. © The Author 2016.

This is a seven year follow up study aiming to determine the incidence of psychotic symptoms and their correlation with other clinical aspects, in particular the rate of development of cognitive impairment.Cohort study of a community-based sample of elderly subjects. At study entry in 2004, the sample was composed of 1,125 individuals aged 60 years and older. Of this total, 547 subjects were re-evaluated in 2011 and submitted to the original study protocol. Of these, 199 showed no psychotic symptoms at phase I, while 64 already had psychotic symptoms in 2004.The incidence of at least one psychotic symptom in the 7 year period was 8.0% (Visual/tactile hallucinations: 4.5%; Persecutory delusions: 3.0%; Auditory hallucinations: 2.5%. Development of psychotic symptoms was associated with epilepsy (OR: 7.75 and 15.83, lower MMSE (OR: 0.72 and reported depression (OR: 6.48. A total of 57.8% of individuals with psychotic symptoms developed cognitive impairment after 7 years. Visual/tactile hallucinations were the only psychotic symptom predictive of this impairment, which was related to lower MMSE and greater functional impairment.The incidence of psychotic symptoms and the conversion rate to cognitive impairment was in the upper range when compared with previous reports. Visual/tactile hallucinations were the most frequent symptoms and were predictive of cognitive impairment over the 7 year period. A significant relationship was found between the incidence of psychotic symptoms and low MMSE scores, as well as clinical comorbities such as epilepsy, reported depression, diabetes and syphilis.

The aim of this study is to discuss diagnostic and therapeutic challenges in a patient with a mutation in the gene responsible for the development of Huntington's disease (HD) who presented schizophrenia-like psychotic symptoms. A case report. A 35-year old man with genetically-confirmed HD who developed significant behavioural changes that occurred many years prior to the outbreak of choreic movements. There was a close temporal relationship between an onset of discrete involuntary movements and schizophrenia-like psychotic symptoms (delusions of persecution, reference and bodily change, as well as auditory pseudohallucinations of threatening and commanding voices). At admission (subsequently to a suicidal attempt) he was ambivalent, ambitendent and--periodically--agitated. Pharmacotherapeutic regime of olanzapine (20 mg qd) and amisulpride (400 mg qd) led to a gradual improvement of the patient's mental status. HD should always be included in the differential diagnosis of psychotic disorders. Patients with HD can exhibit various psychopathological symptoms (including psychotic ones) prior to the outbreak of movement symptoms. Both neurologists and psychiatrists should take part in the therapeutic process. Atypical antipsychotics seem to be effective in the discussed group of patients (although the evidence body consists mainly of scarce, low-quality data).

We investigated the relationship between internalized stigma of mental illness at baseline and depressive and psychotic symptoms 3 and 6 months later, controlling for baseline symptoms. Data on homeless veterans with severe mental illness (SMI) were provided by the Northeast Program Evaluation Center (NEPEC) Special Needs-Chronic Mental Illness (SN-CMI) study (Kasprow and Rosenheck, 2008). The study used the Internalized Stigma of Mental Illness (ISMI) scale to measure internalized stigma at baseline and the Symptom Checklist-90-R (SCL-90-R) to measure depressive and psychotic symptoms at baseline and 3 and 6 month follow-ups. Higher levels of internalized stigma were associated with greater levels of depressive and psychotic symptoms 3 and 6 months later, even controlling for symptoms at baseline. Alienation and Discrimination Experience were the subscales most strongly associated with symptoms. Exploratory analyses of individual items yielded further insight into characteristics of potentially successful interventions that could be studied. Overall, our findings show that homeless veterans with SMI experiencing higher levels of internalized stigma are likely to experience more depression and psychosis over time. This quasi-experimental study replicates and extends findings of other studies and has implications for future controlled research into the potential long-term effects of anti-stigma interventions on mental health recovery.

The present study examined the role of posttraumatic stress symptoms in the relationship between childhood abuse and self-reported psychotic symptoms in severe mental illness. A total of 126 patients diagnosed with major psychiatric conditions with comorbid symptoms of psychosis participated in the present study. The representative psychiatric diagnoses included schizophrenia, bipolar disorder with psychotic features, major depressive disorder with psychotic features, schizoaffective disorder, schizophreniform disorder, and delusional disorder. The Korean Child Trauma Questionnaire measured the type and degree of childhood abuse including emotional, physical, and sexual abuse. Korean version of the Impact of Event Scale-Revised assessed posttraumatic stress symptoms, and PSYC subscale of the PSY-5 Factor Scale of the MMPI-2 was used as a measure of self-reported psychotic symptoms. There was a significant relationship between childhood physical, emotional, sexual abuse and psychotic symptoms. Posttraumatic stress symptoms partially mediated the relationship between childhood abuse and psychotic symptoms. This implies that childhood abuse is significantly associated with the experience of chronic posttraumatic stress symptoms, and that such symptoms in turn increases the likelihood of experiencing psychotic symptoms. The results highlight the need for appropriate assessment and intervention concerning childhood abuse and posttraumatic stress symptoms in severe mental illness.

Several national guidelines recommend continuous use of antipsychotic medication after a psychotic episode in order to minimize the risk of relapse. However some studies have identified a subgroup of patients who obtain remission of psychotic symptoms while not being on antipsychotic medication for a period of time. This study investigated the long-term outcome and characteristics of patients in remission of psychotic symptoms with no use of antipsychotic medication at the 10-year follow-up. The study was a cohort study including 496 patients diagnosed with schizophrenia spectrum disorders (ICD 10: F20 and F22-29). Patients were included in the Danish OPUS Trial and followed up 10years after inclusion, where patient data was collected on socio-demographic factors, psychopathology, level of functioning and medication. 61% of the patients from the original cohort attended the 10-year follow up and 30% of these had remission of psychotic symptoms at the time of the 10-year follow up with no current use of antipsychotic medication. This outcome was associated with female gender, high GAF-F score, participation in the labour market and absence of substance abuse. Our results describe a subgroup of patients who obtained remission while not being on antipsychotic medication at the 10-year follow-up. The finding calls for further investigation on a more individualized approach to long-term treatment with antipsychotic medication. Copyright © 2016 Elsevier B.V. All rights reserved.
Full Text Available Tissue plasminogen activator (tPA mediates a number of processes that are pivotal for synaptogenesis and remodeling of synapses, including proteolysis of the brain extracellular matrix, degradation of adhesion molecules, activation of neurotrophins, and activation of the N-methyl-d-aspartate receptor. Abnormalities in these processes have been consistently described in psychotic disorders. In this paper, we review the physiological roles of tPA, focusing on conditions characterized by low tPA activity, which are prevalent in schizophrenia. We then describe how tPA activity is influenced by lifestyle interventions and nutritional supplements that may ameliorate psychotic symptoms. Next, we analyze the role of tPA in the mechanism of action of hormones and medications effective in mitigating psychotic symptoms, such as pregnenolone, estrogen, oxytocin, dopamine D3 receptor antagonists, retinoic acid, valproic acid, cannabidiol, sodium nitroprusside, N-acetyl cysteine, and warfarin. We also review evidence that tPA participates in the mechanism by which electroconvulsive therapy and cigarette smoking may reduce psychotic symptoms.

Various studies reported remarkably high prevalence rates of obsessive-compulsive symptoms (OCS) in patients with a psychotic disorder. Little is known about the pathogenesis of this co-occurrence. The current study aimed to investigate the contribution of shared underlying risk factors, such as childhood trauma and neuroticism, to the onset and course of OCS in patients with psychosis. Data were retrieved from 161 patients with psychosis included in the 'Genetic Risk and Outcome in Psychosis' project. Patients completed measures of OCS and psychotic symptoms at study entrance and three years later. Additionally, childhood maltreatment and neuroticism were assessed. Between-group comparisons revealed increased neuroticism and positive symptoms in patients who reported comorbid OCS compared to OCS-free patients. Subsequent mediation analyses suggested a small effect of childhood abuse on comorbid OCS severity at baseline, which was mediated by positive symptom severity. Additionally, results showed a mediating effect of neuroticism as well as a moderating effect of positive symptoms on the course of OCS severity over time. OCS severity in patients with psychosis might thus be associated with common vulnerability factors, such as childhood abuse and neuroticism. Furthermore, the severity of positive symptoms might be associated with more severe or persistent comorbid OCS. Copyright © 2017. Published by Elsevier B.V.

Neuropsychological symptoms are rare in familial hemiplegic migraine (FHM). There are no reports of psychotic symptoms in FHM type 2 (ATP1A2). We examined a family with a FHM phenotype due to a M731T mutation in ATP1A2. A 10-year follow-up allowed us to observe complex auras, including psychotic symptoms in two siblings. Male, 48 years old, with an aura that included complex illusions with a feeling of time travelling, coincident with other aura features. The aura was regarded as mystical by the patient. Female, 38 years old, with a complex migraine aura, during which she believed she had the ability to time travel and was being followed by lobbyists who wanted to steal this ability from her. FHM type 2 must be included in the list of differential diagnoses of acute psychosis in patients with a previous history of migraine aura.

Loneliness involves subjective, rather than objective, social isolation and has a range of negative effects on mental and physical functioning. The purpose of this study was to examine the prevalence of loneliness in psychotic disorders and its association with symptoms and cognitive performance. Data were drawn from the second Australian National Survey of Psychosis and comprised responses from 1642 participants with an International Classification of Diseases 10 diagnosis of psychotic disorder who had completed a semi-structured interview of symptoms and social functioning (including loneliness), along with standardized assessments of current (digit symbol coding; DSC) and premorbid (National Adult Reading Test) cognitive ability. We examined the prevalence of loneliness across the diagnostic categories of psychosis, and its association with psychotic and non-psychotic symptoms and digit symbol coding scores. The prevalence of loneliness was high, ranging from 74.75% in participants with delusional disorders to 93.8% in depressive psychosis, and was significantly higher than in the general population. Loneliness was also significantly associated with anhedonia and subjective thought disorder. Participants feeling socially isolated/lonely for company had significantly lower DSC scores than those who only felt lonely occasionally. Unexpectedly, participants who reported not feeling lonely had the lowest DSC scores. Loneliness is common across all psychotic disorders, particularly in depressive psychosis. It is specifically associated with ongoing loss of pleasure and disordered thoughts as well as impairment in current cognitive functioning. However, poor cognitive functioning is not inevitably associated with loneliness. Implications for personalized treatment of psychosis are discussed. Copyright © 2015 Elsevier B.V.

Changes in positive and negative symptom profiles during acute psychotic episodes may be key drivers in the pathway to violence. Acute episodes are often preceded by fluctuations in affect before psychotic symptoms appear and affective symptoms may play a more important role in the pathway than previously recognised. We carried out a prospective cohort study of 409 male and female patients discharged from medium secure services in England and Wales to the community. Measures were taken at baseline (pre-discharge), 6 and 12 months post-discharge using the Positive and Negative Syndrome Scale. Information on violence was obtained using the McArthur Community Violence Instrument and Police National Computer. The larger the shift in positive symptoms the more likely violence occurred in each 6-month period. However, shifts in angry affect were the main driving factor for positive symptom shifts associated with violence. Shifts in negative symptoms co-occurred with positive and conveyed protective effects, but these were overcome by co-occurring shifts in anger. Severe but stable delusions were independently associated with violence. Intensification of angry affect during acute episodes of psychosis indicates the need for interventions to prevent violence and is a key driver of associated positive symptoms in the pathway to violence. Protective effects against violence exerted by negative symptoms are not clinically observable during symptom shifts because they are overcome by co-occurring anger.

Objective To determine whether use of cannabis in adolescence increases the risk for psychotic outcomes by affecting the incidence and persistence of subclinical expression of psychosis in the general population (that is, expression of psychosis below the level required for a clinical diagnosis). Design Analysis of data from a prospective population based cohort study in Germany (early developmental stages of psychopathology study). Setting Population based cohort study in Germany. Participants 1923 individuals from the general population, aged 14-24 at baseline. Main outcome measure Incidence and persistence of subthreshold psychotic symptoms after use of cannabis in adolescence. Cannabis use and psychotic symptoms were assessed at three time points (baseline, T2 (3.5 years), T3 (8.4 years)) over a 10 year follow-up period with the Munich version of the composite international diagnostic interview (M-CIDI). Results In individuals who had no reported lifetime psychotic symptoms and no reported lifetime cannabis use at baseline, incident cannabis use over the period from baseline to T2 increased the risk of later incident psychotic symptoms over the period from T2 to T3 (adjusted odds ratio 1.9, 95% confidence interval 1.1 to 3.1; P=0.021). Furthermore, continued use of cannabis increased the risk of persistent psychotic symptoms over the period from T2 to T3 (2.2, 1.2 to 4.2; P=0.016). The incidence rate of psychotic symptoms over the period from baseline to T2 was 31% (152) in exposed individuals versus 20% (284) in non-exposed individuals; over the period from T2 to T3 these rates were 14% (108) and 8% (49), respectively. Conclusion Cannabis use is a risk factor for the development of incident psychotic symptoms. Continued cannabis use might increase the risk for psychotic disorder by impacting on the persistence of symptoms. PMID:21363868

The prevalence of anxiety symptoms among Australians with psychotic disorders was examined as part of the Survey of High Impact Psychosis (SHIP). A two-phase design was used. Of 7,955 people who were screened positive for psychosis and eligible, there were 1,825 participants (18-34 years and 35-64 years) interviewed. Data were collected on symptomatology, substance use, cognitive ability, functioning, disability, physical health, mental health service utilization, medication use, education, employment and housing. Anxiety symptomatology was divided into generalized anxiety, panic, phobic, social anxiety and obsessive-compulsive symptoms. The most common ICD-10 diagnoses were schizophrenia or schizoaffective disorder (63.0%) and bipolar (mania) disorder (17.5%). Overall, 59.8% (n=1,092) of participants reported experiencing anxiety symptoms in the previous twelve months. Female gender was highly associated with all domains of anxiety. Smoking was significantly associated with all domains of anxiety, except generalized anxiety. The presence of any depressive symptoms in the previous twelve months was significantly associated with all anxiety symptoms. Medication side effects were associated with phobic and obsessive-compulsive symptoms. Social dysfunction was associated with social anxiety, and less so for obsessive-compulsive symptoms. Anxiety symptoms are common in people with psychotic disorders. Appropriate screening and treatment should be a clinical priority.

Psychotic symptoms are a central element in the diagnosis of schizophrenia, although their precise definition has varied through the multiple iterations of DSM and the ICD. Schneiderian first-rank symptoms (FRS) have received a particularly prominent position in the diagnostic criteria of schizophrenia since ICD-9 and DSM-III. In the current iteration of DSM (DSM-IV-TR), whereas two characteristic symptoms are ordinarily required to meet criterion A, only a single symptom is necessary if the psychotic symptom happens to be a FRS, notably a bizarre delusion or auditory hallucination of a running commentary or 'conversing voices'. Because of limited data in support of the special treatment of FRS, DSM-5 has made changes to criterion A, requiring that at least two psychotic symptoms be present in all cases with at least one of these symptoms being a delusion, hallucination, or disorganized speech. To assess the impact of these changes on the prevalence of schizophrenia, we examined a research dataset of 221 individuals with DSM-IV schizophrenia to study the prevalence and co-occurrence of various criterion A symptoms. Although bizarre delusions and/or Schneiderian hallucinations were present in 124 patients (56.1%), they were singly determinative of diagnosis in only one patient (0.46%). Additionally, only three of the 221 patients (1.4%) with DSM-IV schizophrenia did not have a delusion, hallucination, or disorganized speech. DSM-5 changes in criteria A should have a negligible effect on the prevalence of schizophrenia, with over 98% of individuals with DSM-IV schizophrenia continuing to receive a DSM-5 diagnosis of schizophrenia in this dataset.

Full Text Available Multiple sclerosis (MS is a demyelinating disease of the central nervous system. Psychiatric symptoms are not infrequent during MS, yet onset of MS with psychosis is rarely encountered. A 27-year-old Caucasian male was admitted due to numbness in his right arm and difficulty in walking. His clinical and laboratorial exams lead to the MS diagnosis. Nine months earlier, he also developed psychotic disorder, not otherwise specified (PD-NOS. His sudden onset of PD-NOS, his rapid and complete response to antipsychotics, and a relatively short interval between psychiatric and neurological signs indicate a high likelihood that PD-NOS was a manifestation of underlying MS. He also suffers from hypertrophic obstructive cardiomyopathy (HOCM. The patient’s neurological complaints were recovered with methylprednisolone (1 g/day, i.v. given for five days. Glatiramer acetate (1 × 1 tb.s.c. was prescribed for consolidation and, after nine months of his admission, the patient fully recovered from neurological and psychiatric complaints. Interestingly, very recent studies indicate specific alpha-actinin antibodies in MS and alpha-actinin mutations cause HOCM. Thus, concurrence of MS with HOCM can be even a new syndrome, if further genetic studies prove.

Childhood trauma (CT) has been identified as a potential risk factor for the onset of psychotic disorders. However, to date, there is limited consensus with respect to which symptoms may ensue after exposure to trauma in early life, and whether specific pathways may account for these associations. The aim of the present study was to use the novel network approach to investigate how different types of traumatic childhood experiences relate to specific symptoms of psychotic disorders and to identify pathways that may be involved in the relationship between CT and psychosis. We used data of patients diagnosed with a psychotic disorder (n = 552) from the longitudinal observational study Genetic Risk and Outcome of Psychosis Project and included the 5 scales of the Childhood Trauma Questionnaire-Short Form and all original symptom dimensions of the Positive and Negative Syndrome Scale. Our results show that all 5 types of CT and positive and negative symptoms of psychosis are connected through symptoms of general psychopathology. These findings are in line with the theory of an affective pathway to psychosis after exposure to CT, with anxiety as a main connective component, but they also point to several additional connective paths between trauma and psychosis: eg, through poor impulse control (connecting abuse to grandiosity, excitement, and hostility) and motor retardation (connecting neglect to most negative symptoms). The results of the current study suggest that multiple paths may exist between trauma and psychosis and may also be useful in mapping potential transdiagnostic processes. © The Author 2016.

Cannabis use shows a robust dose-dependent relationship with psychosis risk among the general population. Despite this, it has been difficult to link cannabis use with risk for transitioning to a psychotic disorder among individuals at ultra-high risk (UHR) for psychosis. The present study examined UHR transition risk as a function of cannabis use characteristics which vary substantially between individuals including age of first use, cannabis abuse severity and a history of cannabis-induced attenuated psychotic symptoms (APS). Participants were 190 UHR individuals (76 males) recruited at entry to treatment between 2000 and 2006. They completed a comprehensive baseline assessment including a survey of cannabis use characteristics during the period of heaviest use. Outcome was transition to a psychotic disorder, with mean time to follow-up of 5.0 years (range 2.4-8.7 years). A history of cannabis abuse was reported in 58% of the sample. Of these, 26% reported a history of cannabis-induced APS. These individuals were 4.90 (95% confidence interval 1.93-12.44) times more likely to transition to a psychotic disorder (p = 0.001). Greater severity of cannabis abuse also predicted transition to psychosis (p = 0.036). However, this effect was mediated by higher abuse severity among individuals with a history of cannabis-induced APS. Findings suggest that cannabis use poses risk in a subpopulation of UHR individuals who manifest cannabis-induced APS. Whether this reflects underlying genetic vulnerability requires further study. Nevertheless, findings reveal an important early marker of risk with potentially significant prognostic utility for UHR individuals.

Cannabis is the most widely used illicit drug globally, and users are at increased risk of mental illnesses including psychotic disorders such as schizophrenia. Substance dependence and schizophrenia are both associated with dopaminergic dysfunction. It has been proposed, although never directly tested, that the link between cannabis use and schizophrenia is mediated by altered dopaminergic function. We compared dopamine synthesis capacity in 19 regular cannabis users who experienced psychotic-like symptoms when they consumed cannabis with 19 nonuser sex- and age-matched control subjects. Dopamine synthesis capacity (indexed as the influx rate constant [Formula: see text] ) was measured with positron emission tomography and 3,4-dihydroxy-6-[(18)F]-fluoro-l-phenylalanine ([(18)F]-DOPA). Cannabis users had reduced dopamine synthesis capacity in the striatum (effect size: .85; t36 = 2.54, p = .016) and its associative (effect size: .85; t36 = 2.54, p = .015) and limbic subdivisions (effect size: .74; t36 = 2.23, p = .032) compared with control subjects. The group difference in dopamine synthesis capacity in cannabis users compared with control subjects was driven by those users meeting cannabis abuse or dependence criteria. Dopamine synthesis capacity was negatively associated with higher levels of cannabis use (r = -.77, p cannabis use (r = .51, p = .027) but was not associated with cannabis-induced psychotic-like symptoms (r = .32, p = .19). These findings indicate that chronic cannabis use is associated with reduced dopamine synthesis capacity and question the hypothesis that cannabis increases the risk of psychotic disorders by inducing the same dopaminergic alterations seen in schizophrenia.

Background There is increasing interest in elucidating the association of different childhood adversities with psychosis-spectrum symptoms as well as the mechanistic processes involved. This study used experience sampling methodology to examine (i) associations of a range of childhood adversities with psychosis symptom domains in daily life; (ii) whether associations of abuse and neglect with symptoms are consistent across self-report and interview methods of trauma assessment; and (iii) the role of different adversities in moderating affective, psychotic-like, and paranoid reactivity to situational and social stressors. Method A total of 206 nonclinical young adults were administered self-report and interview measures to assess childhood abuse, neglect, bullying, losses, and general traumatic events. Participants received personal digital assistants that signaled them randomly eight times daily for one week to complete questionnaires about current experiences, including symptoms, affect, and stress. Results Self-reported and interview-based abuse and neglect were associated with psychotic-like and paranoid symptoms, whereas only self-reported neglect was associated with negative-like symptoms. Bullying was associated with psychotic-like symptoms. Losses and general traumatic events were not directly associated with any of the symptom domains. All the childhood adversities were associated with stress reactivity in daily life. Interpersonal adversities (abuse, neglect, bullying, and losses) moderated psychotic-like and/or paranoid reactivity to situational and social stressors, whereas general traumatic events moderated psychotic-like reactivity to situational stress. Also, different interpersonal adversities exacerbated psychotic-like and/or paranoid symptoms in response to distinct social stressors. Discussion The present study provides a unique examination of how childhood adversities impact the expression of spectrum symptoms in the real world and lends support
Full Text Available Aims: This study aimed to establish and compare the effects of brief sensory deprivation on individuals differing in trait hallucination proneness. Method: 18 participants selected for high hallucination-proneness were compared against 18 participants rating low on this trait. The presence of psychotic-like experiences, and participants’ cognitive appraisals of these, was evaluated in three different settings: at baseline, in a ‘secluded office’ environment, and in light-and-sound sensory deprivation.Results: Psychotic-like experiences were experienced significantly more often in sensory deprivation for both groups. In particular both experienced slight increases in perceptual distortions and anhedonia in seclusion, and these increased further during sensory deprivation. Highly hallucination prone individuals showed a significantly greater increase in perceptual distortions in sensory deprivation than did non-prone individuals suggesting a state-trait interaction. Their appraisals of these anomalous experiences were compared to both clinical and non-clinical individuals experiencing psychotic symptoms in everyday life.Conclusion: Short-term sensory deprivation is a potentially useful paradigm to model psychotic experiences, as it is a non-pharmacological tool for temporarily inducing psychotic-like states and is entirely safe at short duration. Experiences occur more frequently, though not exclusively, in those at putative risk of a psychotic disorder. The appraisals of anomalous experiences arising are largely consistent with previous observations of non-clinical individuals though importantly lacked the general positivity of the latter.

Psychotic symptoms have been associated with post-traumatic stress disorder and war experiences. However, the relationships between types of war experiences, the onset and course of psychotic symptoms, and post-war hardships in child soldiers have not been investigated. This study assessed whether various types of war experiences contribute to psychotic symptoms differently and whether post-war hardships mediated the relationship between war experiences and later psychotic symptoms. In an ongoing longitudinal cohort study (the War-Affected Youths Survey), 539 (61% male) former child soldiers were assessed for psychotic symptoms, post-war hardships, and previous war experiences. Regression analyses were used to assess the contribution of different types of war experiences on psychotic symptoms and the mediating role of post-war hardships in the relations between previous war experiences and psychotic symptoms. The findings yielded ‘witnessing violence’, ‘deaths and bereavement’, ‘involvement in hostilities’, and ‘sexual abuse’ as types of war experiences that significantly and independently predict psychotic symptoms. Exposure to war experiences was related to psychotic symptoms through post-war hardships (β = .18, 95% confidence interval = [0.10, 0.25]) accounting for 50% of the variance in their relationship. The direct relation between previous war experiences and psychotic symptoms attenuated but remained significant (β = .18, 95% confidence interval = [0.12, 0.26]). Types of war experiences should be considered when evaluating risks for psychotic symptoms in the course of providing emergency humanitarian services in post-conflict settings. Interventions should consider post-war hardships as key determinants of psychotic symptoms among war-affected youths. PMID:24718435

Shedding light on this under-researched matter could have clinical implications for this patient group. This was a secondary analysis of a randomized, parallel-group, superiority, assessor-blinded trial. We followed 60 patients with dually diagnosed psychosis and cannabis use disorders from the Danish CapOpus trial, which included assessments at baseline, post-treatment (6 months) and 10 months. Cannabis use was registered by self-report assisted by timeline follow-back. Psychotic symptoms were measured using the Positive and Negative Syndrome Scale (PANSS) positive, negative, and general symptoms scores. Analyses were adjusted for potential confounders. Patients were classified into four categories: minor use (0-30 joints at baseline and 0-9 joints at follow-up; n = 19), moderate use (0-30 joints at baseline and 10-196 joints at follow-up; n = 11), high (reducing) use (31-240 joints at baseline and 0-9 joints at follow-up; n = 9), and severe use (31-240 joints at baseline and 10-196 joints at follow-up; n = 21). Those with severe and persistent cannabis use (severe use group) had significantly higher scores, as compared to those with minor use, on the positive symptom (17.0, 95% CI [4.7-19.2] vs. 12.7, 95% CI [10.4-15.0], respectively, adjusted p cannabis use and psychosis. Treatment of psychosis and comorbid cannabis use disorder could in the future incorporate treatment strategies emphasising encouragement to reduce cannabis use. CapOpus is registered at clinicaltrials.gov (NCT00484302).

It has been well documented that cocaine and methamphetamine use can lead to the onset of psychotic symptoms similar to schizophrenia. However, the research and literature on gender differences and stimulant-induced psychosis have been mixed. The primary aim of this study was to investigate gender differences in the reporting of psychotic symptoms in cocaine- versus methamphetamine-dependent individuals. Participants were recruited from the Los Angeles, California, community via radio and newspaper advertisements. All met Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria for cocaine or methamphetamine dependence, and all reported either methamphetamine or cocaine as their primary drug of abuse. During a screening interview, participants answered questions from the Psychotic Symptom Assessment Scale, which characterizes various types of psychotic symptoms during drug use ("while high") or during periods of nonuse ("while abstinent"). Participants included 42 cocaine-dependent individuals (27 men, 15 women) and 43 methamphetamine-dependent individuals (25 men, 18 women). Among cocaine users, there were no significant differences between men and women with regard to ethnicity, years of use, route of administration, and amount used in the past week, though they differed significantly with regard to age (P = 0.029). In the "while abstinent" condition, women were significantly more likely than men to report experiencing auditory hallucinations (13% vs 0%, respectively; P = 0.050) and tactile hallucinations (20% vs 0%; P = 0.016), whereas men were more likely to report delusions of grandeur (48% vs 6%; P = 0.006). During the "while high" condition, women were significantly more likely than men to report delusions of grandeur (13% vs 0%, respectively; P = 0.050), tactile hallucinations (33% vs 0%; P = 0.001), and olfactory hallucinations (13% vs 0%; P = 0.050). Among methamphetamine users, there were no significant differences between men and

Cocaine consumption can induce transient psychotic symptoms expressed as paranoia or hallucinations. This work reviews that evidence and tries to obtain data regarding frequency of psychotic symptoms or cocaine induced psychosis (CIP), risks or associated factors. Systematic review of studies found in PubMed database published until January 2011 where cocaine induced paranoia was present. Cocaine induced paranoia has a particular clinical presentation. It needs to be clearly identified due to its harmful consequences. The prevalence is between 12% in clinical studies and 100% in experimental studies. The following are considered potential risk factors: age of first use and length, amount of substance, route of administration, body mass index, genetic factors, personal vulnerability and comorbidity with AXIS I (psychosis, ADHD) and AXIS II disorders (antisocial personality disorder). It is needed to research with larger samples of cocaine users of different countries and contexts, in order to identify and detail what variables are closely related in the development of cocaine induced paranoia, so the population at risk can be treated earlier.

Mephedrone (4-methylmethcathinone) is a synthetic stimulant drug of the cathinone class. Similar effects to those of cocaine and ecstasy are reported by users, with a high addictive potential. Given its increasing rate of consumption in Europe, it is getting more and more attention from the addiction field. In spite of that, little is known about the long-term consequences of prolonged heavy use. The two following cases might depict some of them. Case 1 was a middle-age man who reported three years of intravenous use of mephedrone. He used to binge for several days in a row. Psychotic symptoms appeared after a few months, especially paranoid delusions. Sent to aftercare in a therapeutic community, delusions kept reappearing after prolonged abstinence. A good response to risperidone was observed. Case 2 was a young man who used mephedrone heavily for two years, always snorted. Upon admission to the therapeutic community, the patient reported auditory hallucinations that partially remitted with olanzapine. Both cases showed a good insight and no personality deterioration. Given its similarities to other substances that are known to induce psychotic symptoms, and the increasing consumption of mephedrone around Europe, similar cases are expected in the near future. Conventional antipsychotic treatment seems a reasonable pharmacological approach.

There is significant variation in the expression of schizophrenia across ethnically different populations, and the optimal structural and diagnostic representation of schizophrenia are contested. We contrasted both lifetime frequencies of DSM-IV criterion A (the core symptom criterion of the internationally recognized DSM classification system) symptoms and types/content of delusions and hallucinations in transethnic schizophrenia populations from Australia (n = 776), India (n = 504) and Sarawak, Malaysia (n = 259), to elucidate clinical heterogeneity. Differences in both criterion A symptom composition and symptom content were apparent. Indian individuals with schizophrenia reported negative symptoms more frequently than other sites, whereas individuals from Sarawak reported disorganized symptoms more frequently. Delusions of control and thought broadcast, insertion, or withdrawal were less frequent in Sarawak than Australia. Curiously, a subgroup of 20 Indian individuals with schizophrenia reported no lifetime delusions or hallucinations. These findings potentially challenge the long-held view in psychiatry that schizophrenia is fundamentally similar across cultural groups, with differences in only the content of psychotic symptoms, but equivalence in structural form.

Studies on both personality dimensions and cognition in schizophrenia are scarce. The objective of the present study was to examine personality traits and the relation to cognitive function and psychotic symptoms in a sample of patients with schizophrenia and healthy controls. In total 23 patients with schizophrenia and 14 controls were assessed with the Karolinska Scales of Personality (KSP). A broad cognitive test programme was used, including the Wechsler Adult Intelligence Scales, the Finger-Tapping Test, the Trail Making Test, the Verbal Fluency Test, the Benton Visual Retention Test, the Wisconsin Card Sorting Test and Rey Auditory Verbal Learning Test . Compared with controls, the patients exhibited prominent elevations on KSP scales measuring anxiety proneness and neuroticism (P = 0.000005-0.0001), on the Detachment scale (P controls. KSP anxiety-related scales correlated with the Positive and Negative Symptoms Scale (PANSS) general psychopathology subscale. Cognitive test results were uniformly lower in the patient group and correlated with PANSS negative symptoms subscale. There was no association between KSP scale scores and PANSS positive or negative symptoms. The patients revealed a highly discriminative KSP test profile with elevated scores in neuroticism- and psychoticism-related scales as compared to controls. Results support previous findings utilizing other personality inventories in patients with schizophrenia. Cognitive test performance correlated inversely with negative symptoms.

This study involved the examination of the relationship between childhood trauma and both psychotic symptoms and suicidality in patients with schizophrenia after controlling for the possible confounding factors, such as clinical features, depression, and sleep quality. The Childhood Trauma Questionnaire-Short Form, Positive and Negative Syndrome Scale (PANSS), Calgary Depression Scale for Schizophrenia (CDSS), Pittsburgh Sleep Quality Index (PSQI), and the suicidality subscale of Mini-International Neuropsychiatric Interview (MINI) were administered to 199 patients with schizophrenia. We used sequential multiple stepwise regression analyses in which positive symptoms, negative symptoms, overall psychopathology, total symptoms of schizophrenia, and suicidality were dependent variables. Depressive symptomatology and childhood physical abuse significantly contributed to positive, negative, general psychopathology, and global schizophrenia symptomatology. Interestingly, general psychopathology scores were negatively associated with childhood physical neglect. Also, subjective sleep quality significantly contributed to positive schizophrenia symptoms. Although prior suicide attempts and depression were significant antecedents of suicidal ideation, no association between suicidality and both childhood trauma and sleep was found. Childhood physical abuse could have an impact on psychopathology in schizophrenia. In addition to childhood trauma, depression, sleep disturbances, and clinical features should be considered and inquired about in the course of clinical care of schizophrenia patients.

Patients suffering from multiple sclerosis (MS) can often dysplay psychiatric symptoms throughout the disease. The frequency of those symptoms could be two or three times greater in MS patients compared to the general population. Psychotic symptoms could be an early sign of MS. At first, neurological symptoms can either be mild or altogether absent. MRI brain scans show cerebral lesions in frontal and temporal regions. New MRI sequencing techniques support the hypothesis that disseminated defects in the grey matter occur in MS. These defects could in turn be responsible for cognitive disorders. Patients presenting a first-episode psychosis must have a neurological examination. MS should be considered as an alternative diagnosis of psychosis, particularly in atypical cases where family history of psychosis is absent and where there is bad response to standard psychotropic treatment. Collaboration between neurologists and psychiatrists whilst caring for patients displaying neuropsychiatric manifestations of MS is crucial to enable more accurate diagnoses and try to improve treatment and overall prognosis.

Full Text Available There have been no repeat surveys of psychotic symptoms in Kenya or indeed subSaharan Africa. A mental health epidemiological survey was therefore conducted in a demographic surveillance site of a Kenyan household population in 2013 to test the hypothesis that the prevalence of psychotic symptoms would be similar to that found in an earlier sample drawn from the same sample frame in 2004, using the same overall methodology and instruments. This 2013 study found that the prevalence of one or more psychotic symptoms was 13.9% with one or more symptoms and 3.8% with two or more symptoms, while the 2004 study had found that the prevalence of single psychotic symptoms in rural Kenya was 8% of the adult population, but only 0.6% had two symptoms and none had three or more psychotic symptoms. This change was accounted for by a striking increase in psychotic symptoms in women (17.8% in 2013 compared with 6.9% in 2004, p < 0.001, whereas there was no significant change in men (10.6% in 2013 compared with 9.4% in 2004, p = 0.582. Potential reasons for this increase in rate of psychotic symptoms in women are explored.

BACKGROUND: Few studies have evaluated the development in the use of antipsychotic medication and psychotic symptoms in patients with first-episode psychosis on a long-term basis. Our objective was to investigate how psychotic symptoms and the use of antipsychotic medication changed over a 10-year...... in Copenhagen and Aarhus, Denmark. RESULTS: At all follow-ups, a large proportion (20-30%) of patients had remission of psychotic symptoms without use of antipsychotic medication at the time of the follow-up. Patients who were in this group at the 5-year follow-up had an 87% [95% confidence interval (CI) 77......-96%] chance of being in the same group at the 10-year follow-up. This stability was also the case for patients who had psychotic symptoms and were treated with antipsychotic medication at year 5, where there was a 67% (95% CI 56-78%) probability of being in this group at the consecutive follow-up.

While attenuated psychotic symptoms (APS) and basic symptoms (BS) are the main current predictors of psychosis in adults, studies in adolescents are scarce. Thus, we (1) described the prevalence and severity of positive, negative, disorganization, general, and basic symptoms in adolescent patients at ultra-high risk for psychosis (UHR), with other non-psychotic psychiatric disorders (PC) and with early-onset psychosis (EOP); and (2) investigated BS criteria in relation to UHR criteria. Sixty-nine 12-18-year-old adolescents (15.3 ± 1.7 years, female = 58.0 %, UHR = 22, PC = 27, EOP = 20) were assessed with the structured interview for prodromal syndromes (SIPS) and the schizophrenia proneness instrument-child and youth version (SPI-CY). Despite similar current and past 12-month global functioning, both UHR and EOP had significantly higher SIPS total and subscale scores compared to PC, with moderate-large effect sizes. Expectedly, UHR had significantly lower SIPS positive symptom scores than EOP, but similar SIPS negative, disorganized, and general symptom scores. Compared to PC, both EOP and UHR had more severe basic thought and perception disturbances, and significantly more often met cognitive disturbances criteria (EOP = 50.0 %, UHR = 40.9 %, PC = 14.8 %). Compared to UHR, both EOP and PC significantly less often met cognitive-perceptive BS criteria (EOP = 35.0 %, UHR = 68.2 %, PC = 25.9 %). BS were significantly more prevalent in both EOP and UHR than PC, and UHR were similar to EOP in symptom domains. Given the uncertain outcome of adolescents at clinical high-risk of psychosis, future research is needed to determine whether the combined assessment of early subjective disturbances with observable APS can improve the accuracy of psychosis prediction.

We examined the prevalence rates of Internet gaming disorder among South Korean middle school students, the dominant symptoms of Internet gaming disorder, and the interrelationships between such disorder and non-psychotic psychological symptoms (ie, anxiety, depression, and impulsiveness) and with physical aggression. Data were collected from a national sample of 2024 students (70.3% gamers; 50.6% boys). Gaming disorder and prevalent symptoms were measured by the 9 diagnostic criteria proposed in DSM-5. Our results showed 5.9% of the sample (boys 10.4%, girls 1.2%) was classified as adolescents with gaming disorder. Meanwhile, 8% (boys 14.2%, girls 5.9%) of the sample was found to be at high risk of gaming disorder. The prevalent symptoms were mood modification, behavioral salience, conflict, withdrawal, and relapse, in that order. A total of 9.2%, 15.1%, and 10.9% of the adolescents with gaming disorder had non-psychotic psychological anxiety, depression, and impulsiveness symptoms, respectively. Nearly 11% of students with Internet gaming disorder had 2 non-psychotic psychological symptoms or more. These results provide supportive empirical evidence that Internet gaming disorder can lead to severe distress and that it can be associated with comorbid symptoms that are relevant to development or continuance of the gaming disorder.

To provide a rational basis for reconceptualizing catatonia in Diagnostic and Statistical Manual of Mental Disorders (Fifth Edition), we briefly review historical sources, the psychopathology of catatonia, and the relevance of catatonic schizophrenia in contemporary practice and research. In contrast to Kahlbaum, Kraepelin and others (Jaspers, Kleist, and Schneider) recognized the prevalence of motor symptoms in diverse psychiatric disorders but concluded that the unique pattern and persistence of certain psychomotor phenomena defined a "catatonic" subtype of schizophrenia, based on intensive long-term studies. The enduring controversy and confusion that ensued underscores the fact that the main problem with catatonia is not just its place in Diagnostic and Statistical Manual of Mental Disorders but rather its lack of conceptual clarity. There still are no accepted principles on what makes a symptom catatonic and no consensus on which signs and symptoms constitute a catatonic syndrome. The resulting heterogeneity is reflected in treatment studies that show that stuporous catatonia in any acute disorder responds to benzodiazepines or electroconvulsive therapy, whereas catatonia in the context of chronic schizophrenia is phenomenologically different and less responsive to either modality. Although psychomotor phenomena are an intrinsic feature of acute and especially chronic schizophrenia, they are insufficiently recognized in practice and research but may have significant implications for treatment outcome and neurobiological studies. While devising a separate category of catatonia as a nonspecific syndrome has heuristic value, it may be equally if not more important to re-examine the psychopathological basis for defining psychomotor symptoms as catatonic and to re-establish psychomotor phenomena as a fundamental symptom dimension or criterion for both psychotic and mood disorders.

Personality in patients with psychosis, and particularly its relation to psychotic symptoms in recent onset of psychosis (ROP) patients, is understudied. The aims of this research were to study the relation between dimensional and categorical clinical personality traits and symptoms, as well as the effects that symptoms, sex and age have on clinically significant personality traits. Data for these analyses were obtained from 94 ROP patients. The Millon Clinical Multiaxial Inventory and the Positive and Negative Syndrome Scale were used to assess personality and symptoms. Correlational Analysis, Mann-Whitney test, and, finally, logistic regression were carried out. The negative dimension was higher in patients with schizoid traits. The excited dimension was lower for those with avoidant and depressive traits. The anxiety and depression dimension was higher for patients with dependent traits. The positive dimension was lower for patients with histrionic and higher for patients with compulsive traits. Logistic regression demonstrated that gender and the positive and negative dimensions explained 35.9% of the variance of the schizoid trait. The excited dimension explained 9.1% of the variance of avoidant trait. The anxiety and depression dimension and age explained 31.3% of the dependent trait. Gender explained 11.6% of the histrionic trait, 14.5% of the narcissistic trait and 11.6% of the paranoid trait. Finally gender and positive dimension explained 16.1% of the compulsive trait. The study highlights the importance of studying personality in patients with psychosis as it broadens understating of the patients themselves and the symptoms suffered. Copyright © 2017 Elsevier Inc.

Although the aetiology of psychotic symptoms in Alzheimer's disease (AD) is multi-factorial, alterations in serotonergic neurotransmission are often implicated. Polymorphisms of the serotonin receptor 5HT-2A are associated with hallucinatory symptoms and delusions in demented and non-demented cohorts. This study examined the role of the 5HT-2A T102C polymorphism in influencing psychotic symptoms in a large Northern Ireland AD population (n = 406, mean MMSE 13/30). Forty-eight percent of patients experienced delusional symptoms and 28% experienced hallucinations during the course of their dementia. No significant association was found either in frequency of genotype or allelic variation for either set of symptoms. Furthermore, the mean delusional and hallucinatory severity scores did not differ significantly among the three genotype groups. The lack of influence of the T102C polymorphism of the 5HT-2A receptor on the emergence of psychotic symptoms in AD contrasts with previous reports in other cohorts involving smaller numbers of subjects.

The present study is the first to investigate, using conversation analysis, the effects of a family member’s participation in conversation regarding the assessment of need for treatment. We aim at describing the course of a treatment negotiation, focusing on interactional dynamics and on disclosure of paranoid symptoms in a clinically challenging situation characterized by an acutely psychotic patient with (1) disorganized discourse, (2) poor insight, (3) aspiration to avoid hospital treatment, and (4) a relative who was supporting in-patient care. In the triadic conversation, in which the patient, his relative, and the psychiatrist participated, different consecutive phases were distinguished. The Relative Prominent Information Phase (RIP) was characterized by the relative’s statements on the patient’s problematic behavior, and conflicting views between the patient and his relative led to denial of symptoms by the patient. When the patient was prominent in the latter Patient Prominent Information Phase (PIP), the display of several different social actions and corresponding linguistic devices were linked with more overt talk about paranoid experiences by the patient, albeit in a disorganized manner. RIP and PIP were followed by an Evaluation and Decision Phase (EDP).
Full Text Available Objectives. The aim of this naturalistic study was to investigate whether treatment with clozapine and other atypical antipsychotics for at least 2 years was associated with a reduction in psychotic and depressive symptoms and an improvement in chronic schizophrenia patients’ awareness of their illness. Methods. Twenty-three adult outpatients (15 men and 8 women treated with clozapine and 23 patients (16 men and 7 women treated with other atypical antipsychotics were included in the study. Psychotic symptoms were evaluated using the Positive and Negative Syndrome Scale (PANSS, depressive symptoms were assessed with the Calgary Depression Scale for Schizophrenia (CDSS, and insight was assessed with the Scale to Assess Unawareness of Mental Disorder (SUMD. Results. The sample as a whole had a significant reduction in positive, negative, and general symptoms, whereas the reduction in depression was significant only for patients with CDSS scores of 5 and higher at the baseline. At the follow-up, patients treated with other atypical antipsychotics reported a greater reduction in depression than patients treated with clozapine, but not when limiting the analyses to those with clinically relevant depression. Conclusions. Atypical antipsychotics may be effective in reducing psychotic and depressive symptoms and in improving insight in patients with chronic schizophrenia, with no differences in the profiles of efficacy between compounds.

. To examine racial-ethnic differences in the endorsement and attribution of psychotic-like symptoms in a nationally representative sample of African-Americans, Asians, Caribbean Blacks, and Latinos living in the USA. Data were drawn from a total of 979 respondents who endorsed psychotic-like symptoms as part of the National Latino and Asian American Study (NLAAS) and the National Survey of American Life (NSAL). We use a mixed qualitative and quantitative analytical approach to examine sociodemographic and ethnic variations in the prevalence and attributions of hallucinations and other psychotic-like symptoms in the NLAAS and NSAL. The lifetime presence of psychotic-like symptoms was assessed using the World Health Organization Composite International Diagnostic Interview (WMH-CIDI) psychotic symptom screener. We used logistic regression models to examine the probability of endorsing the four most frequently occurring thematic categories for psychotic-like experiences by race/ethnicity (n > 100). We used qualitative methods to explore common themes from participant responses to open ended questions on their attributions for psychotic-like symptoms. African-Americans were significantly less likely to endorse visual hallucinations compared to Caribbean Blacks (73.7% and 89.3%, p supernatural, ghosts/unidentified beings, death and dying, spirituality or religiosity, premonitions, familial and other. Respondents differed by race/ethnicity in the attributions given to psychotic like symptoms. Findings suggest that variations exist by race/ethnicity in both psychotic-like symptom endorsement and in self-reported attributions/understandings for these symptoms on a psychosis screening instrument. Ethnic/racial differences could result from culturally sanctioned beliefs and idioms of distress that deserve more attention in conducting culturally informed and responsive screening, assessment and treatment.

The PSYRATS has been translated into different language versions and has been validated for clinical and research use mainly in chronic psychotic patients but not in recent-onset psychosis patients or in Chinese populations. The psychometric analysis of the translated Chinese version included assessment of its content validity, semantic equivalence, interrater and test–retest reliability, reproducibility, sensitivity to changes in psychotic symptoms, internal consistency, concurrent validity (compared to a valid psychotic symptom scale, and factor structure. The Chinese version demonstrated very satisfactory content validity as rated by an expert panel, good semantic equivalence with the original version, and high interrater and test–retest (at 2-week interval reliability. It also indicated very good reproducibility of and sensitivity to changes in psychotic symptoms in line with the symptom severity measured with the Positive and Negative Syndrome Scale (PANSS. The scale consisted of four factors for the hallucination subscale and two factors for the delusion subscale, explaining about 80% of the total variance of the construct, indicating satisfactory correlations between the hallucination and delusion factors themselves, between items, factors, subscales, and overall scale, and

Scott, a 13-year 7-month old white male with no prior psychiatric history, presented to the emergency department after three days of decreased attention span and increased distractibility. An initial examination revealed that he was internally preoccupied (focused on responding to auditory hallucinations), displayed thought blocking (sudden interruption in the flow of his thoughts that prevented him from completing an idea), and he had periodic vague suicidal ideation due to intense guilt. He noted hearing two to three voices accusing him of being rude during an incident with a peer at school. He could not accept reassurance from his mother and grandparents that this incident had not actually occurred. Scott found evidence of his wrongdoing by misinterpreting words on signs and medical equipment that he felt indicated that others also knew of his malicious actions. A recent stressor included the conclusion of his active football season a day prior to the onset of his symptoms. Scott and his family denied a history of prodromal symptoms, mental or medical illnesses, including head injury. After a physical/neurological examination, a negative urine drug screen, and a normal complete blood count and metabolic panel, Scott was transferred to a psychiatric hospital. Scott returned to the emergency department two days later with worsening psychotic symptoms despite a trial of olanzapine. He had deteriorated dramatically from his initial presentation. He was now rigid, unable to speak, move his body, follow directions, eat, drink, or provide any additional history. After being admitted to the pediatrics floor an extensive medical workup was completed that included neurology and infectious disease consults, brain magnetic resonance imaging and angiography studies, a 24-hour electroencephalogram, lumbar puncture, urinalysis, complete blood count, comprehensive metabolic panel, ceruloplasm, anti-nuclear antibody, anti-DNAase, erythrocyte sedimentation rate, heavy metal
Full Text Available Fibromyalgia is characterized by chronic widespread pain, clinical symptoms that include cognitive and sleep disturbances, and other abnormalities such as increased sensitivity to painful stimuli, increased sensitivity to multiple sensory modalities, and altered pain modulatory mechanisms. Here we relate experimental findings of fibromyalgia symptoms to anatomical and functional brain changes. Neuroimaging studies show augmented sensory processing in pain-related areas, which, together with gray matter decreases and neurochemical abnormalities in areas related to pain modulation, supports the psychophysical evidence of altered pain perception and inhibition. Gray matter decreases in areas related to emotional decision making and working memory suggest that cognitive disturbances could be related to brain alterations. Altered levels of neurotransmitters involved in sleep regulation link disordered sleep to neurochemical abnormalities. Thus, current evidence supports the view that at least some fibromyalgia symptoms are associated with brain dysfunctions or alterations, giving the long-held “it is all in your head” view of the disorder a new meaning.

To portray the emotional and behavioral reactions of persons with dementia to the delusions and hallucinations they experience, according to the reports of their family caregivers. The article also explores the relationship between those reactions and background variables. Study participants were family caregivers of 74 older persons with a diagnosis of dementia (aged ≥ 65) residing in the community recruited from adult day centers and support groups for caregivers of persons with dementia and by advertising online. Assessments included the Behavioral Pathology in Alzheimer's Disease, the Neuropsychiatric Inventory, the Etiological Assessment of Psychotic Symptoms in Dementia, Activities of Daily Living questionnaire, and the Mini-Mental State Examination. Findings concerning emotional reactions reveal that close to half of the delusions resulted in discomfort, whereas around 40% did not. We found significant differences in the discomfort associated with different types of delusions, with delusions of abandonment, danger, and infidelity associated with more discomfort than other delusions. Around half of the delusions were associated with a behavioral manifestation. The findings highlight the need to examine the emotional impact of delusions and hallucinations as part of their assessment and as a consideration in treatment decisions.

Epidemiological evidence suggests risk for psychosis varies with ethnicity in Western countries. However, there is little evidence to date on the cross-cultural validity of screening instruments used for such comparisons. Combining two existing UK population-based cohorts, we examined risk for reporting psychotic symptoms across White British (n = 3467), White Irish (n = 851), Caribbean (n = 1899), Indian (n = 2590), Pakistani (n = 1956) and Bangladeshi groups (n = 1248). We assessed the psychometric properties of the Psychosis Screening Questionnaire (PSQ) with a multiple-group confirmatory factor analysis, assessing the equivalence of factor loadings, response thresholds and residual variances in an analysis of measurement non-invariance. Compared with prevalence among British Whites (5.4%), the prevalence of self-reported psychotic symptoms was greater in the Caribbean group (12.7%, adjusted OR = 2.38 [95% CI 1.84-3.07]). Prevalence was also increased among Pakistani individuals (8.3%, adjusted OR = 1.36 [1.01-1.84]) although this difference was driven by a greater likelihood of reporting paranoid symptoms. PSQ items for thought interference, strange experience and hallucination were measured in equivalent ways across ethnic groups. However, our measurement models suggested that paranoid symptoms were measured less reliably among ethnic minorities than among British Whites and appeared to exaggerate latent differences between Pakistani and White British groups when measurement non-invariance was not accounted for. Notwithstanding evidence for measurement non-invariance, the greater risk for reporting psychotic symptoms among Caribbean individuals is unlikely to be an artefact of measurement. Greater residual variance in the recording of paranoid symptoms among ethnic minority respondents warrants caution in using this item to investigate ethnic variation in psychosis risk.

Full Text Available A psychosis phenotype can be observed below the threshold of clinical detection. The study aimed to investigate whether subclinical psychotic symptoms are associated with deficits in controlling emotional interference, and whether cortical brain and cardiac correlates of these deficits can be detected using functional near-infrared spectroscopy (fNIRS. A data set derived from a community sample was obtained from the Zurich Program for Sustainable Development of Mental Health Services. 174 subjects (mean age 29.67 ± 6.41, 91 females were assigned to four groups ranging from low to high levels of subclinical psychotic symptoms (derived from the Symptom Checklist-90-R. Emotional interference was assessed using the emotional Stroop task comprising neutral, positive, and negative conditions. Statistical distributional methods based on delta plots (behavioral response time data and quantile analysis (fNIRS data were applied to evaluate the emotional interference effects.Results showed that both interference effects and disorder-specific (i.e., group-specific effects could be detected, based on behavioral response times, cortical hemodynamic signals (brain correlates, and heart rate variability (cardiac correlates. Subjects with high compared to low subclinical psychotic symptoms revealed significantly reduced amplitudes in dorsolateral prefrontal cortices (interference effect, p < 0.001 and middle temporal gyrus (disorder-specific group effect, p < 0.001, supported by behavioral and heart rate results. The present findings indicate that distributional analyses methods can support the detection of emotional interference effects in the emotional Stroop. The results suggested that subjects with high subclinical psychosis exhibit enhanced emotional interference effects. Based on these observations, subclinical psychosis may therefore prove to represent a valid extension of the clinical psychosis phenotype.

Racial discrimination is related to depression, anxiety, and severe psychological distress, and evidence drawn from studies emanating from the United Kingdom and The Netherlands suggest racial discrimination is also related to clinical psychosis and subthreshold psychotic symptoms in racial and ethnic minority (REM) populations. The present study sought to determine the association between racial discrimination experiences and attenuated positive psychotic symptoms (APPS) in a United States (US) urban, predominantly immigrant and REM young adult population. A cohort of 650 young adults was administered a self-report inventory for psychosis risk [i.e., Prodromal Questionnaire (PQ)], and the Experiences of Discrimination Questionnaire. The PQ allowed the dimensional assessment of APPS, as well as the categorical assessment of a potentially "high risk" group (i.e., 8 or more APPS endorsed as distressing), the latter of which was based on previous validation studies using the structured interview for prodromal syndromes. The relations between self-reported racial discrimination and APPS, and racial discrimination and "high" distressing positive PQ endorsement were determined, while accounting for anxiety and depression symptoms. Racial discrimination was significantly associated with APPS and with significantly higher odds of endorsing eight or more distressing APPS, even after adjusting for anxiety and depression symptoms. The present study provides preliminary evidence that racial discrimination among US ethnic minorities may be associated with APPS, as well as potentially higher risk for psychosis.

The objective of the study was to explore the content of existing online resources available to information-seeking youth as psychotic symptoms first emerge and determine how these resources may influence initiation of care. Using 18 hypothetical search terms, developed by the Early Treatment Programme (ETP) staff, we searched three of the most popular websites used by the youth (Google, Facebook and Twitter) and extracted the first five hits from each. Sites were categorized into those that encouraged help seeking, those that potentially contribute to treatment delay, those with an undetermined impact and those that were unrelated to treatment. An alarmingly few of the first five hits from the top three online resources encourage potentially psychotic youth to seek professional evaluation. The majority of our search results yielded unmonitored chat forums that lacked a unified message. The remainder promoted stigma, normalized potentially psychotic experiences or were completely unrelated to mental health. We must develop innovative, easy-to-access and youth-focused online and social media experiences that encourage symptomatic youth to seek care. © 2014 Wiley Publishing Asia Pty Ltd.
population isolates and in the general population. Vulnerabilities to early onset alcohol and drug use disorders do not lend convincing support to a diathesis-stressor model with these stressors, commonly reported with these tribes. Nearly one-fifth of the respondents reported experiencing psychotic-like symptoms, reaffirming the need to examine sociocultural factors actively before making positive diagnoses of psychosis or schizophrenia.

Kurt Schneider defined 'first rank symptoms' (FRS) of psychosis. Previous research found two clusters of FRS: 'loss of ego bound' symptoms (e.g., delusions of external control) and auditory hallucinations (e.g, commenting voices). In patients with a psychosis we investigated whether FRS are a separate cluster within the group of positive symptoms, consisting of two underlying factors that are stable over time. We conducted a principal axis factor analysis (PAF) at baseline (n = 857) and a confirmative factor analysis (CFA) at three-year follow-up (n = 414) on (FRS) symptom score. Also, we investigated the stability of the two-factor structure of FRS over the interval. PAF on 16 items representing positive symptoms at baseline revealed two factors with eigenvalues > 1. FRS-delusional self experience (thought withdrawal, thought broadcasting, thought insertion, and beliefs that impulses and/or actions are controlled by an outside force) clustered in one factor and FRS-auditory hallucinations (auditory hallucinations, conversational voices, and voices commenting on one's actions) in the second factor. Furthermore, CFA on the FRS-items at follow-up confirmed the two-factor structure of FRS. FRS delusional self experience and FRS-auditory hallucinations at baseline were significantly associated with the same factors at three-year follow-up (FRS-delusional self experience: r = 0.38; FRS-auditory hallucinations r = 0.47). Hence, our findings confirm a two-factor structure of first rank symptoms, i.e. FRS-delusional self experience and FRS-auditory hallucinations, with a moderate to large internal coherence within each factor and relative stability over time. Future studies on self-processes may contribute to our understanding of the pathophysiology of first rank symptoms. Copyright © 2013 Elsevier B.V. All rights reserved.

The objective of this study was to replicate the association between atypical handedness and psychosis-proneness in a representative sample of adolescents from the general population. It expands previous studies by (1) analyzing a variety of atypical handedness indexes (left, mixed, ambiguous, and inconsistent), (2) measuring comprehensively the multidimensionality of psychosis-proneness, and (3) analyzing the association of different patterns of atypical handedness with nonclinical dimensions of both trait (schizotypy) and sub-clinical symptom (psychotic-like experiences) levels. Seven hundred and twenty-eight adolescents were assessed for handedness by the 12-item self-report Annett Hand Preference Questionnaire and for psychosis-proneness by the Oxford-Liverpool Inventory of Feelings and Experiences and the Community Assessment of Psychic Experiences scales. Writing-hand alone did not detect associations between laterality and psychosis-proneness. Mixed- rather than left-handedness was related to psychosis-proneness, and this was more evident when analyzing subjects with ambiguous handedness exclusively. When analysis was restricted to subjects with non-ambiguous handedness, strong left-handedness was related to psychosis-proneness. The positive dimension showed a stronger association than the negative one with atypical handedness. Results partially support mixed-handedness as a marker of developmental disorders underlying both atypical lateralization and psychosis-proneness. Among various possible mixed-handedness patterns, inconsistent hand use across primary actions, and for the same action across time, seems particularly related to psychosis-proneness and thus requires further exploration.

22q11.2 Microdeletion syndrome (22qDS) is caused by a recurrent genetic mutation associated with a high degree of social impairment, and also represents one of the greatest known genetic risk factors for schizophrenia. This syndrome therefore represents an excellent model for investigating how a known genetic "lesion" may lead to abnormal development of social behavior and to the expression of a diagnosable psychotic disorder. However, little is known about vulnerabilities that contribute to...

Self-generated coping strategies and the enhancement of coping strategies are effective in the treatment of psychotic symptoms. Evaluating these strategies can be of clinical interest to develop better coping enhancement therapies. Cognitive models consider delusions as multidimensional phenomena. Using a psychometric approach, the relationship between coping and the dimensions of delusion were examined. Thirty schizophrenia spectrum patients with delusions and 29 patients with affective disorder with psychotic symptoms were interviewed using the Heidelberg Coping Scales for Delusions and the Heidelberg Profile of Delusional Experience. Analyses of variance were conducted to investigate differences between the groups, and Spearman's rank-based correlations were used to examine the correlations between coping factors and the dimensions of delusion. Schizophrenia spectrum patients used more medical care and symptomatic coping, whereas patients with affective disorder engaged in more depressive coping. In the schizophrenia spectrum sample, the action-oriented, the cognitive, and the emotional dimensions of delusion were related to coping factors. In patients with affective disorder, only the action-oriented dimension was related to coping factors. Patients with schizophrenia and affective disorder cope differently with delusions. The dimensions of delusion are related to coping and should be regarded when using cognitive therapy approaches to enhance coping strategies. © 2014 S. Karger AG, Basel.

22q11.2 deletion syndrome (22q11DS) represents one of the largest known genetic risk factors for psychosis, yet the neurobiological mechanisms underlying symptom development are not well understood. Here we conducted a cross-sectional study of 22q11DS to decompose cortical volume into its constituent parts, cortical thickness (CT) and surface area (SA), which are believed to have distinct neurodevelopmental origins. High-resolution T1-weighted scans were collected on 65 participants (31 22q11DS, 34 demographically comparable typically developing controls, 10-25 years old). Measures of cortical volume, CT, and SA were extracted from regions of interest using the FreeSurfer image analysis suite. Group differences and age-related trajectories in these structures, as well as their association with psychotic symptomatology, were assessed. Relative to controls, 22q11DS participants showed bilateral volumetric reductions in the inferior temporal cortex, fusiform gyrus, anterior cingulate, superior parietal cortex, and cuneus, which were driven by decreased SA in these regions. 22q11DS participants also had increased volumes, driven by increased CT, in bilateral insula regions. 22q11DS youth had increased CT in frontal regions, particularly middle frontal and medial orbitofrontal cortices. A pattern of age-associated cortical thinning was observed in typically developing controls in brain regions associated with visual and sensory information-processing (i.e., left pericalcarine cortex and fusiform gyrus, right lingual and postcentral cortices). However, this relationship was disrupted in 22q11DS participants. Finally, correlational analyses revealed that increased CT in right medial orbitofrontal cortex was associated with increased positive symptom severity in 22q11DS. Differential disruptions of CT and SA in distinct cortical regions in 22q11DS may indicate abnormalities in distinct developmental neural processes. Further, neuroanatomic abnormalities in medial frontal

The primary aim of this study was to explore the potential moderating effect of social support on the relation between distress caused by psychosis risk symptoms and self-stigma among college students with mental health diagnoses. Participants were young adult college students who endorsed having a past or present mental health diagnosis (n = 63). Self-report data were examined from the Prodromal Questionnaire-Brief, a measure of subthreshold psychosis risk symptoms; the Self-Concurrence/Application subscale of the Self-Stigma of Mental Illness Scale, a measure of self-stigma; and the Friendships subscale of the Lubben Social Network Scale-Revised, a measure of social support from peers. There was a modest direct relation between distress associated with psychosis risk symptoms and self-stigma. There was a larger relation between distress from risk symptoms and self-stigma for those with low social support compared to those with mean and high social support. Although causality cannot be determined based on this study, a strong relation between symptom distress and stigma was found among those reporting low peer social support. Interventions that target both self-stigma and social support might be relevant for young adults with a history of mental health concerns who currently endorse subthreshold psychotic symptoms.

Psychotic-like symptoms are found in a subgroup of borderline patients (BPD). Reported prevalence is heterogeneous (up to 50% affected). Investigations in Germany have not been conducted so far. Furthermore, the precise phenomenology of the psychotic symptoms and the effects on suicidal behavior and the use of inpatient psychiatric treatment are unclear. The aim of the study was to investigate prevalence rates and phenomenology of psychotic-like symptoms. Associations between the latter and suicidality as well as the use of inpatient psychiatric treatment were examined. Further influencing factors were taking into account. Psychotic-like symptoms were assessed with the Structured Clinical Interview-I in 95 BPD patients. To investigate the associations between psychotic-like symptoms and suicidality as well as the use of inpatient psychiatric treatment, correlation and regression analyzes were calculated, considering severity of PTSD, BPD and depression. 36% of the patients reported alterations of perception and 21% delusions, both multiform and long lasting. The number of suicide attempts was associated with delusions, alterations of perception and severity of PTSD, BPS, and depression. Only delusions and severity of PTSD explained together 25.8% of the variance for the prediction of the number of suicide attempts. Age of initial hospitalization showed fewer and number of hospitalizations no associations at all. Psychotic-like symptoms should not be trivialized, which may happen by using terms such as pseudo-hallucinations or transient paranoid ideas, and may be particularly associated with suicidal tendencies complicating the clinical course. © Georg Thieme Verlag KG Stuttgart · New York.

Cocaine, the third mostly commonly used illicit drug in the United States, has a wide range of neuropsychiatric effects, including transient psychotic symptoms. When psychotic symptoms occur within a month of cocaine intoxication or withdrawal, the diagnosis is cocaine-induced psychotic disorder (CIPD). Current evidence suggests those with CIPD are likely to be male, have longer severity and duration of cocaine use, use intravenous cocaine, and have a lower body mass index. Differentiating CIPD from a primary psychotic disorder requires a detailed history of psychotic symptoms in relation to substance use and often a longitudinal assessment. Treatment includes providing a safe environment, managing agitation and psychosis, and addressing the underlying substance use disorder. This review begins with a clinical case and summarizes the literature on CIPD, including clinical presentation, differential diagnosis, mechanism and predictors of illness, and treatment.

The clinical effectiveness of non-pharmacological interventions on behavioral and psychological symptoms of dementia (BPSD) among older Chinese with dementia remains unclear, and the evidence supporting the benefits of a non-pharmacological approach on psychotic symptoms is scarce. A prospective cohort study including 104 older men with dementia living in two veterans homes in Taiwan was carried out in 2011. An organized program of music therapy, orientation training, art-cognitive activities and physical activities was carried out for the intervention group. All participants were evaluated for neuropsychiatric inventory (NPI), defined daily dose of psychotropic drug use, Barthel Index, Instrumental Activities of Daily Living, Mini-Mental State Examination, Geriatric Depression Scale, Tinetti balance score and Tinetti gait score. Overall, 104 residents were enrolled and 92 of them completed the study. The intervention group had a more significant reduction than the reference group in the overall NPI score (-2.36, P = 0.046), and in the subcategories of delusion (-0.9, P = 0.018), hallucination (-0.82, P = 0.004) and agitation (-0.91, P = 0.038). Multivariate analysis showed that the non-pharmacological intervention was associated with a favorable outcome in overall NPI score (OR 4.113, P = 0.013) and in the subcategories of hallucination (OR 14.309, P = 0.049) and agitation (OR 6.604, P = 0.037). Meanwhile, a higher baseline NPI score was also associated with a favorable outcome in overall NPI score, and in the subcategories of delusion, hallucination and agitation. Non-pharmacological interventions have a positive effect on behavioral and psychological symptoms of dementia, not only in outward symptoms like agitation, but also intrinsic psychotic symptoms like hallucination and delusion, and agitation in older Chinese men with dementia. © 2013 Japan Geriatrics Society.

Cannabis use and childhood maltreatment are independent risk factors for the development of psychotic symptoms. These factors have been found to interact in some but not all studies. One of the reasons may be that childhood maltreatment and cannabis primarily induce psychotic symptoms in genetically susceptible individuals. In this context, an extensively studied psychosis vulnerability gene is catechol-methyl-transferase (COMT). Therefore, we aimed to examine whether the COMT Val(158)Met polymorphism (rs4680) moderates the interaction between childhood maltreatment and cannabis use on psychotic symptoms in the general population. The discovery sample consisted of 918 individuals from a cross-sectional study. For replication we used an independent sample of 339 individuals from the general population. A significant three-way interaction was found between childhood maltreatment, cannabis use, and the COMT genotype (rs4680) in the discovery sample (P=0.006). Val-homozygous individuals displayed increased psychotic experiences after exposure to both cannabis use and childhood maltreatment compared to Met-heterozygous and Met-homozygous individuals. Supportive evidence was found in the replication sample with similar effect and direction even though the results did not reach statistical significance (P=0.25). These findings suggest that a functional polymorphism in the COMT gene may moderate the interaction between childhood maltreatment and cannabis use on psychotic experiences in the general population. In conclusion, the COMT Val(158)Met polymorphism may constitute a genetic risk factor for psychotic symptoms in the context of combined exposure to childhood maltreatment and cannabis use. © 2013 Elsevier B.V.

The 22q11.2 deletion syndrome (22q11.2DS) is one of the most common microdeletion syndromes, with a widely underestimated prevalence between 1 per 2000 and 1 per 6000. Since childhood, patients with 22q11.2DS are described as having difficulties to initiate and maintain peer relationships. This lack of social skills has been linked to attention deficits/hyperactivity disorder, anxiety and depression. A high incidence of psychosis and positive symptoms is observed in patients with 22q11.2DS and remains correlated with poor social functioning, anxiety and depressive symptoms. Because 22q11.2DS and schizophrenia share several major clinical features, 22q11.2DS is sometimes considered as a genetic model for schizophrenia. Surprisingly, almost no study suggests the use of cognitive and behavioral therapy (CBT) in this indication. We reviewed what should be learned from schizophrenia to develop specific intervention for 22q11.2DS. In our opinion, the first step of CBT approach in 22q11.2DS with psychotic symptoms is to identify precisely which tools can be used among the already available ones. Cognitive behavioral therapy (CBT) targets integrated disorders, i.e. reasoning biases and behavior disorders. In 22q11.2DS, CBT-targeted behavior disorders may take the form of social avoidance and withdrawal or, in the contrary, a more unusual disinhibition and aggressiveness. In our experience, other negative symptoms observed in 22q11.2DS, such as motivation deficit or anhedonia, may also be reduced by CBT. Controlled trials have been studying the benefits of CBT in schizophrenia and several meta-analyses proved its effectiveness. Therefore, it is legitimate to propose this tool in 22q11.2DS, considering symptoms similarities. Overall, CBT is the most effective psychosocial intervention on psychotic symptoms and remains a relevant complement to pharmacological treatments such as antipsychotics.

Drug abuse is reported to be on the increase among young persons using illicit substances but little is known about the frequency with which they occur, the symptoms on presentation to health institutions, and the different substances abused. To establish this, we reviewed patient data collected at Al-Amal Hospital in Jeddah Kingdom of Saudi Arabia on young persons who are refered to the hospital for problems related to drug abuse. Data on 69 adolescent drug users were reviewed and analyzed using the Composite International Diagnostic Interview - Substance Abuse Model (CIDI-SAM) to assess dependence on substances including amphetamines, cannabis, cocaine, and opioids. Furthermore, we assessed the adolescents' data on history of delusions and hallucinations in the context of use of, or withdrawal from, these specific substances. Our analysis shows that 10 to 79.6% of users of amphetamines, cannabis, cocaine, and opiates met DSM-III-R dependence criteria for each specific substance. The prevalence of psychotic symptoms associated with each specific substance ranged from users with no diagnosis to users with severe dependence as follows: amphetamines (3-100%), cannabis (7-60.0%), cocaine (5-70.7%), and opiates (4-88%). The risk of psychotic symptoms increased for respondents who abused (OR=7.2) or had mild (OR=8.1), moderate (OR=20.0), or severe dependence (OR=14.0) on cocaine when compared to those who were users with no diagnosis. A similar pattern was evident in cannabis, opiate, and amphetamine users. In conclusion, most adolescent drug users in Saudi Arabia who are dependent on illicit substances experience psychotic symptoms in the context of use of, or withdrawal from, these substances. Psychotic symptoms increased with the severity of the disorders associated with use of all four substances. These findings underscore the importance of developing services to target this population; a population at risk of developing psychotic symptoms.

AIMS: The aim of this study was to estimate the effects of lifestyle interventions on bodyweight and other cardiometabolic risk factors in people with psychotic disorders. Additionally, the long-term effects on body weight and the effects on depressive symptoms were examined. MATERIAL AND METHODS:
Neurocognitive dysfunction is likely to represent a trait characteristic of bipolar disorder, but the extent to which it comprises \\'core\\' deficits as opposed to those secondary to longstanding illness or intellectual decline is unclear. We investigated neuropsychological performance in an epidemiologically derived sample of patients with a first affective episode with psychotic symptoms and a positive history of mania, compared to community controls.

Schizophrenia is a common disorder, affecting approximately 1 out of every 100 people, with a typical onset during adolescence and early adulthood. The personal and societal costs of schizophrenia are extremely high. Prevention of schizophrenia, would offer substantial benefits to patients, their family members, and the community at large. The prodromal phase of schizophrenia has been recognized since the 19th century. At-risk individuals for psychosis and schizophrenia are the subjects who can provide information for intervention prior to development of frank psychosis. This approach is currently being investigated. The question remains, however, whether it can be a diagnostic category by itself. The proposal for including the risk syndrome is one of the recommendations by the working group on schizophrenia and psychotic disorders for the forthcoming DSM-V. There are differing views in academia regarding this proposal. Prior to becoming fully psychotic, a consistent literature demonstrates that patients generally had suffered from accelerating attenuated symptoms and distress. It is important that the prodromal phase be accurately recognized in order to accomplish the goal of prevention. We can then purposefully engage in early intervention aiming toward prevention. A recent strong resurgent interest in this area stems largely from two developments: First, the identification of the neurobiological deficit processes associated with the severity and chronicity of schizophrenia, and second, the development of reliable criteria for diagnosis. Although the general at-risk construct appears to offer great potential to advance both the treatment and research dealing with psychotic illnesses, it seems premature to many researchers to include the syndrome as an established entity in the text of the new DSM-V. It would be far more appropriate to include this proposed syndrome in the appendix and evaluate the many contemporary issues in future studies. The main issues

Cannabis users are more likely to have psychotic experiences (PEs). The degree to which these associations are driven by genetic or environmental influences in adolescence is unknown. This study estimated the genetic and environmental contributions to the relationship between cannabis use and PEs. Specific PEs were measured in a community-based twin sample (4830 16-year-old pairs) using self-reports and parent-reports. Adolescents reported on ever using cannabis. Multivariate liability threshold structural equation model-fitting was conducted. Cannabis use was significantly correlated with PEs. Modest heritability (37%), common environmental influences (55%) and unique environment (8%) were found for cannabis use. For PEs, modest heritability (27–54%), unique environmental influences (E=12–50%) and little common environmental influences (11–20%), with the exception of parent-rated Negative Symptoms (42%), were reported. Environmental influences explained all of the covariation between cannabis use and paranoia, cognitive disorganization and parent-rated negative symptoms (bivariate common environment=69–100%, bivariate unique environment=28–31%), whilst the relationship between cannabis use and hallucinations indicated familial influences. Cannabis use explains 2–5% of variance in positive, cognitive, and negative PEs. Cannabis use and psychotic experience co-occur due to environmental factors. Focus on specific environments may reveal why adolescent cannabis use and psychotic experiences tend to ‘travel together’. PMID:25912376

This pilot study aimed to evaluate the feasibility of an assessor-blind, randomised controlled trial of psychodynamic art therapy for the treatment of patients with schizophrenia, and to generate preliminary data on the efficacy of this intervention during acute psychotic episodes. Fifty-eight inpatients with DSM-diagnoses of schizophrenia were randomised to either 12 twice-weekly sessions of psychodynamic group art therapy plus treatment as usual or to standard treatment alone. Primary outcome criteria were positive and negative psychotic and depressive symptoms as well as global assessment of functioning. Secondary outcomes were mentalising function, estimated with the Reading the mind in the eyes test and the Levels of emotional awareness scale, self-efficacy, locus of control, quality of life and satisfaction with care. Assessments were made at baseline, at post-treatment and at 12 weeks' follow-up. At 12 weeks, 55% of patients randomised to art therapy, and 66% of patients receiving treatment as usual were examined. In the per-protocol sample, art therapy was associated with a significantly greater mean reduction of positive symptoms and improved psychosocial functioning at post-treatment and follow-up, and with a greater mean reduction of negative symptoms at follow-up compared to standard treatment. The significant reduction of positive symptoms at post-treatment was maintained in an attempted intention-to-treat analysis. There were no group differences regarding depressive symptoms. Of secondary outcome parameters, patients in the art therapy group showed a significant improvement in levels of emotional awareness, and particularly in their ability to reflect about others' emotional mental states. This is one of the first randomised controlled trials on psychodynamic group art therapy for patients with acute psychotic episodes receiving hospital treatment.

The Psychotic Symptom Rating Scales (PSYRATS) is the most widely used validated scale to measure the specific symptoms of auditory hallucination and delusion. The aim of this study was to validate and to examine the psychometric properties of the auditory hallucination component of the Malay PSYRATS (MyPSYRATS). The research was done in the Universiti Kebangsaan Malaysia Medical Center (UKMMC) among 51 schizophrenia inpatients and outpatients who had experienced or reported verbal auditory hallucination. The psychometric properties of MyPSYRATS (auditory hallucination) were studied and a comparison was made between the psychometric properties obtained and the Positive and Negative Syndrome Scale (PANSS). The internal consistency of MyPSYRATS was good as revealed by Cronbach's alpha value. Factor analysis replicated three components (emotional, cognitive, and physical) similar to the factorial structure of the original auditory hallucination scale. However, two items were regrouped under the emotional component. Spearman's rank-order correlation showed a significant positive relationship between the total score of auditory hallucinations and PANSS auditory hallucinations item (P3). In conclusion, the auditory hallucination domain of MyPSYRATS is a reliable and valid assessment tool for further clinical applications. Copyright © 2015. Published by Elsevier Ireland Ltd.

Delusions and hallucinations are classic positive symptoms of schizophrenia. A contemporary cognitive theory called the 'forward output model' suggests that the misattribution of self-generated actions may underlie some of these types of symptoms, such as delusions of control - the experience of self-generated action being controlled by an external agency. In order to examine the validity of this suggestion, we performed a longitudinal functional magnetic resonance imaging (fMRI) study examining neuronal activation associated with motor movement during acute psychosis. We studied brain activation using fMRI during a motor task in 11 patients with schizophrenia and 9 healthy controls. The patient group was tested at two time points separated by 6-8 weeks. At initial testing, the patient group had a mean Positive and Negative Syndrome Scale score of 56.3, and showed significantly increased activation within the left inferior parietal lobe (IPL) compared to controls. Patients reported significantly decreased positive symptoms at 6-8 week followup and IPL activation had returned to normal. Our results demonstrate that first-rank positive symptoms are associated with hyperactivation in the secondary somatosensory cortex (IPL). These findings lend further credence to the theory that a dysfunction in the sensory feedback system located in the IPL, and which is thought to underlie our sense of agency, may contribute to the aetiology of delusions of control.

In patients with psychotic disorders, the effects of psychological post-traumatic stress disorder (PTSD) treatment on symptoms of psychosis, depression and social functioning are largely unknown In a single-blind randomized controlled trial (RCT) 155 outpatients in treatment for psychosis (61.3% schizophrenic disorder, 29% schizoaffective disorder) were randomized to eight sessions prolonged exposure (PE; n = 53) or eye movement desensitization and reprocessing (EMDR) (n = 55), or a waiting-list condition (WL, n = 47) for treatment of their co-morbid PTSD. Measures were performed on (1) psychosis: severity of delusions (PSYRATS-DRS), paranoid thoughts (GPTS), auditory verbal hallucinations (PSYRATS-AHRS), and remission from psychotic disorder (SCI-SR-PANSS); (2) depression (BDI-II); (3) social functioning (PSP). Outcomes were compared at baseline, post-treatment, 6-month follow-up and over all data points. Both PE and EMDR were significantly associated with less severe paranoid thoughts post-treatment and at 6-month follow-up, and with more patients remitting from schizophrenia, at post-treatment (PE and EMDR) and over time (PE). Moreover, PE was significantly associated with a greater reduction of depression at post-treatment and at 6-month follow-up. Auditory verbal hallucinations and social functioning remained unchanged. In patients with chronic psychotic disorders PE and EMDR not only reduced PTSD symptoms, but also paranoid thoughts. Importantly, in PE and EMDR more patients accomplished the status of their psychotic disorder in remission. Clinically, these effects are highly relevant and provide empirical support to the notion that delivering PTSD treatment to patients with psychotic disorders and PTSD deserves increasing recognition and acceptance among clinicians.

Full Text Available A framework is described for understanding the schizophrenic syndrome at the brain systems level. It is hypothesized that over-activation of dynamic gesture and social perceptual processes in the temporal-parietal occipital junction (TPJ, posterior superior temporal sulcus (PSTS and surrounding regions produce the syndrome (including positive and negative symptoms, their prevalence, prodromal signs and cognitive deficits. Hippocampal system hyper-activity and atrophy have been consistently found in schizophrenia. Hippocampal activity is highly related to activity in the TPJ and may be a source of over-excitation of the TPJ and surrounding regions. Strong evidence for this comes from in-vivo recordings in humans during psychotic episodes. The TPJ and PSTS play a key role in the perception (and production of dynamic social, emotional and attentional gestures for the self and others (e.g., body/face/eye gestures, audiovisual speech, prosody. The single cell representation of dynamic gestures is multimodal (auditory, visual, tactile, matching the predominant hallucinatory categories in schizophrenia. Inherent in the single cell perceptual signal of dynamic gesture representations is a computation of intention, agency, and anticipation or expectancy (for the self and others. The neurons are also tuned or biased to detect threat related emotions. Abnormal over-activation in this system could produce the conscious hallucination of a voice (audiovisual speech, person or a touch. Over-activation could interfere with attentional/emotional gesture perception and production (negative symptoms. It could produce the unconscious feeling of being watched, followed or of a social situation unfolding along with accompanying perception of intent and agency inherent in those representations (delusions. Cognitive disturbances in attention, predictive social processing, agency, working memory, and a bias toward the perception of threat would also be predicted.

The use of cannabis during the early stage of psychosis has been linked with increased psychotic symptoms. This study aimed to examine the use of cannabis in the 12 months following a first-episode of psychosis (FEP) and the link with symptomatic course and outcome over 1 year post psychosis onset. One thousand twenty-seven FEP patients were recruited upon inception to specialized early intervention services (EIS) for psychosis in the United Kingdom. Participants completed assessments at baseline, 6 and 12 months. The results indicate that the use of cannabis was significantly associated with increased severity of psychotic symptoms, mania, depression and poorer psychosocial functioning. Continued use of cannabis following the FEP was associated with poorer outcome at 1 year for Positive and Negative Syndrome Scale total score, negative psychotic symptoms, depression and psychosocial functioning, an effect not explained by age, gender, duration of untreated psychosis, age of psychosis onset, ethnicity or other substance use. This is the largest cohort study of FEP patients receiving care within EIS. Cannabis use, particularly "continued use," was associated with poorer symptomatic and functional outcome during the FEP. The results highlight the need for effective and early intervention for cannabis use in FEP. © The Author 2015.

There is a dearth of research on what factors are predictive of insight among people with severe mental illness and co-occurring PTSD. Data were drawn from 146 participants with severe mental illness, co-occurring PTSD and elevated psychotic symptoms participating in a randomized controlled trial comparing two interventions for PTSD among people with severe mental illness. We examined the clinical and demographic correlates of insight at baseline, the relationship between baseline insight and treatment participation, the relationship between treatment participation and post-treatment insight, and the relationship between change in insight and change in other clinical variables. Impaired insight was relatively common, with roughly half the sample demonstrating mild or moderate impairment at baseline. Baseline insight was associated with fewer psychotic and disorganized symptoms, and greater emotional discomfort and PTSD knowledge, but was not associated with negative symptoms, PTSD symptoms, depression/anxiety, or treatment participation. Participation in PTSD treatment was associated with increased insight at post-treatment. Improved insight was associated with improvements in disorganization and negative symptoms, but not with knowledge of PTSD or positive symptoms. The findings suggest that engagement in treatment that includes educating people about PTSD may lead to improvements in insight and related improvements in other psychiatric symptoms.

Antipsychotics are the mainstay of schizophrenia treatment. However, approximately one third of schizophrenic patients do not respond or respond poorly to antipsychotics. Therefore, there is a need for new approaches that can improve schizophrenia treatment significantly. Promising strategies arise from the modulation of glutamatergic system, according to its proposed involvement in schizophrenia pathogenesis. In this review, we critically updated preclinical and clinical data on the modulation of glutamate N-methyl-D-aspartate (NMDA) receptor activity by NMDA-Rs co-agonists, glycine transporters inhibitors, AMPAkines, mGluR5 agonists, NMDA-Rs partial agonists. We focused on: 1) preclinical results in animal models mimicking the pathophysiology of psychosis, mainly believed to be responsible of negative and cognitive symptoms, and predicting antipsychotic-like activity of these compounds; and 2) clinical efficacy in open-label and double-blind trials. Albeit promising preclinical findings for virtually all compounds, clinical efficacy has not been confirmed for D-cycloserine. Contrasting evidence has been reported for glycine and D-serine, that may however have a role as add-on agents. More promising results in humans have been found for glycine transporter inhibitors. AMPAkines appear to be beneficial as pro-cognitive agents, while positive allosteric modulators of mGluR5 have not been tested in humans. Memantine has been proposed in early stages of schizophrenia, as it may counteract the effects of glutamate excitotoxicity correlated to high glutamate levels, slowing the progression of negative symptoms associated to more advanced stages of the illness.

Kynurenic acid (KYNA), a metabolite of the kynurenine pathway, is emerging as a key factor in the development of psychotic disorders. Increased levels of KYNA are found in the brain and cerebrospinal fluid (CSF) of patients with schizophrenia and bipolar disorder, and are associated to psychotic symptoms. The unique pharmacological profile of KYNA allows it to exert actions on all the main neurotransmitter systems of the brain. The kynurenine pathway is under immunologica...

The symptoms of psychiatric illness are diverse, as are the causes of the conditions that cause them. Yet, regardless of the heterogeneity of cause and presentation, a great deal of symptoms can be explained by the failure of a single perceptual function--the reprocessing of ecological perception. It is a central tenet of the ecological theory of perception that we perceive opportunities to act. It has also been found that perception automatically causes actions and thoughts to occur unless this primary action pathway is inhibited. Inhibition allows perceptions to be reprocessed into more appropriate alternative actions and thoughts. Reprocessing of this kind takes place over the entire frontal lobe and it renders action optional. Choice about what action to take (if any) is the basis for the feeling of autonomy and ultimately for the sense-of-self. When thoughts and actions occur automatically (without choice) they appear to originate outside of the self, thereby providing prima facie evidence for some of the bizarre delusions that define schizophrenia such as delusional misidentification, delusions of control and Cotard's delusion. Automatic actions and thoughts are triggered by residual stimulation whenever reprocessing is insufficient to balance automatic excitatory cues (for whatever reason). These may not be noticed if they are neutral and therefore unimportant or where actions and thoughts have a positive bias and are desirable. Responses to negative stimulus, on the other hand, are always unwelcome, because the actions that are triggered will carry the negative bias. Automatic thoughts may include spontaneous positive feelings of love and joy, but automatic negative thoughts and visualisations are experienced as hallucinations. Not only do these feel like they emerge from elsewhere but they carry a negative bias (they are most commonly critical, rude and are irrationally paranoid). Automatic positive actions may include laughter and smiling and these are

Low levels of self-esteem have been implicated as both a cause and a consequence of severe mental disorders. The main aims of the study were to examine whether premorbid adjustment has an impact on the subject's self-esteem, and whether lowered self-esteem contributes to the development of delusions and hallucinations. A total of 113 patients from the Thematically Organized Psychosis research study (TOP) were included at first treatment. The Positive and Negative Syndrome Scale (PANSS) was used to assess present symptoms. Premorbid adjustment was measured with the Premorbid Adjustment Scale (PAS) and self-esteem by the Rosenberg Self-Esteem Scale (RSES). Premorbid social adjustment was significantly related to lower self-esteem and explained a significant proportion of the variance in self-esteem. Self-esteem was significantly associated with the levels of persecutory delusions and hallucinations experienced by the patient and explained a significant proportion of the variance even after adjusting for premorbid functioning and depression. There are reasons to suspect that premorbid functioning is an important aspect in the development of self- esteem, and, furthermore, that self-esteem is associated with the development of delusions and hallucinations.

CASE PRESENTATION At age 8, “Chris,” a Caucasian boy, experienced intermittent auditory and visual hallucinations, but without bizarre behaviors or much deterioration in functioning. At age 15, he developed a depressed mood, started talking to himself, and became socially withdrawn, and his academic performance declined. He was hospitalized and diagnosed as having major depressive disorder with psychotic features. MRI and EEG showed no abnormalities. Treatment with escitalopram (10 mg/day) and aripiprazole (5 mg/day) had little effect. Several weeks after discharge, he was admitted for a second time with the same diagnosis; a third admission, again with the same diagnosis, occurred several months after that. At age 16, Chris developed visual and auditory hallucinations with homicidal ideations. He cut himself superficially following the command of voice hallucinations, and he was hospitalized again, with the diagnosis changed to schizophrenia, paranoid type. During this inpatient stay, he was treated with venlafaxine (150 mg/day) and risperidone (1.5 mg/day). During the same admission, a blood test showed the presence of antinuclear antibodies (ANAs), but the patient had no symptoms of any autoimmune disease. In the meantime, he was also receiving clindamycin/benzoyl peroxide and adapaline gels and minocycline for acne and fluticasone nasal spray and albuterol for asthma. An allergy to gluten was demonstrated by an assay (Accessa Labs) that showed only IgE antigluten antibodies. Chris’sparents reported that he developed anallergy to peanuts and soy at about the same time. Gluten was removed from his diet at the suggestion of the mother, a licensed dietitian. After the dietary change, the intensity of Chris’s auditory hallucinations declined dramatically and the violent element diminished, and he was discharged after 9 weeks. During the next 2 years, Chris remained on a gluten-free diet, which he and his family associated with the disappearance of his

High rates of obsessive-compulsive symptoms (OCS) in schizophrenia require pathogenic explanations. Personality traits may represent risk and resiliency factors for the development of mental disorders and their comorbidities. The aim of the present study was to explore the associations between Five-Factor Model (FFM) personality traits and the liability for OCS in patients with psychotic disorders and in their un-affected siblings. FFM traits, occurrence and severity of OCS and (subclinical) psychotic symptoms were assessed in 208 patients and in 281 siblings. Differences in FFM traits between participants with vs. without comorbid OCS were examined and the predictive value of FFM traits on group categorization was evaluated. Associations between FFM traits and OCS severity were investigated. Patients and siblings with OCS showed significantly higher Neuroticism compared to their counterparts without OCS. Neuroticism was positively associated with higher OCS severity and significantly predicted group assignment in both patients and in siblings. Patients with comorbid OCS presented with lower scores on Extraversion and Conscientiousness. Higher Neuroticism, and to a lesser degree lower Extraversion and Conscientiousness might add to the vulnerability of patients with a psychotic disorder to also develop OCS. Future prospective studies are needed to elucidate proposed personality-psychopathology interrelations and possible mediating factors. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Full Text Available Abstract Background In Low and Middle Income Countries, mental health services are often poorly developed due to the lack of resources and trained personnel. In order to overcome these challenges, new ways of care have been suggested such as a focus on community-based services. In Somalia, the consumption of the natural stimulant khat is highly prevalent, aggravating mental illness. At the same time, mental health care is largely unavailable to the vast majority of the population. In a pilot project, we tested possibilities for effective measures in community-based out-patient mental health care. Methods Thirty-five male patients with chronic psychotic disorders and their carers were involved in a 10-months follow-up study. All of them abused khat. Seventeen outpatients experiencing acute psychotic episodes were recruited from the community and received an intensive six week home-based treatment package. Additionally eighteen patients with chronic psychotic disorders in remission were recruited either following hospital discharge or from the community. In a second phase of the study, both groups received community-based relapse prevention that differed in the degree of the family’s responsibility for the treatment. The treatment package was comprised of psycho-education, low-dose neuroleptic treatment, monthly home visits and counseling. The Brief Psychiatric Rating Scale (BPRS was applied three times. Additionally, we assessed functioning, khat use and other outcomes. Results Of the 35 patients enrolled in the study, 33 participated in the 10-month follow-up. Outpatients improved significantly in the first six weeks of treatment and did not differ from remitted patients at the start of the second treatment phase. In the preventive treatment phase, we find heterogeneous outcomes that diverge between symptom and functioning domains. With the exception of depressive symptoms, symptoms in all patients tended to worsen. The outpatient group had
Epidemiological research has shown that hallucinations and delusions, the classic symptoms of psychosis, are far more prevalent in the population than actual psychotic disorder. These symptoms are especially prevalent in childhood and adolescence. Longitudinal research has demonstrated that psychotic symptoms in adolescence increase the risk of psychotic disorder in adulthood. There has been a lack of research, however, on the immediate clinicopathological significance of psychotic symptoms in adolescence.

This study aimed to investigate the mediating pathway of 3 factors (psychotic symptoms, attitude toward medication, and cognitive processing speed) on the effect of insight on personal-social functioning in patients with schizophrenia. Chinese inpatients with schizophrenia (n = 168; mean age 18 ± 50 years) diagnosed according to the DSM-IV were randomly assigned to treatment with antipsychotic medication alone or combined treatment. Positive and Negative Syndrome Scale (PANSS), Drug Attitude Inventory (DAI), Assessment of Insight (SAI), and Social-Personal Performance Scale (PSPS) scores were evaluated at baseline and at 3, 6, and 12 months. Cognitive function was assessed at baseline. Multiple mediation analyses were conducted with baseline data, end point data, and changes-in-scale scores between baseline and the end point, respectively. At baseline and at 12 months, only psychotic symptoms mediated the effect of insight on personal-social functioning. For changes-in-scale scores over the 12-month follow-up, in patients receiving treatment with medication alone, the effect of improved insight on improved personal-social function was mediated by psychotic symptoms only; in patients receiving a combined treatment, the effect of improved insight on improved personal-social functioning was mediated by both psychotic symptoms and attitudes toward medication, independently. The link between insight and personal-social functions is mainly mediated by psychotic symptoms. Psychosocial intervention improves the predicting effect of insight on personal-social function by improving both the attitude toward medication and psychotic symptoms independently. © 2018 S.

The comparison of the locus of control in groups of patients hospitalised due to alcohol withdrawal with and without delirium and analysis of psychotic experiences of patients with delirium. 25 patients with alcohol withdrawal with delirium and 25 without delirium took part in the study. They filled-in the Internal-External (I-E) Locus of Control Scale by Rotter; Multidimensional Health Locus of Control (MHLC) scale; the group with delirium also did the Psychopathological Symptoms Inventory, by Bizoń et al. The mean score in I-E Locus of Control Scale in the group with delirium was more external than in the group without delirium (M = 13.28; SD = 2.762 versus M = 11.64; SD = 2.612; t(48) = -2.157; p = 0.036). Group with delirium had also lower mean score in the dimension of internal control in MHLC, than the group without delirium (M = 24.8; SD = 6.149 versus M = 26.8; SD = 4.648; t(48) = 1.99; p = 0.04). There were no statistically significant differences between the groups in the other subscales. The auditory and visual hallucinations were most common among patients with delirium (84%, 80% respectively, as well as delusions of taking part in not existing events (92%) and persecutory delusions (80%). Psychotic experiences influenced behaviour in nearly 50% of the cases. A more external locus of control may be one of the factors contributing to the development of alcohol delirium. The content of psychotic experiences seems to have impact on the behaviour of many patients with alcohol delirium.

We report about two patients with denial of pregnancy. While the first patient was free of psychopathological symptoms besides denial of pregnancy until rupture of the membranes, and was able to accomodate the new born, the second patient with psychotic denial of pregnancy could not accomodate the child because of the schizophrenia, so that an adoption was necessary. On the basis of the two cases aetiological, epidemiological, clinical und prognostic implications of psychotic and non-psychotic denial of pregnancy are discussed. © Georg Thieme Verlag KG Stuttgart · New York.

Schizophrenia can be a devastating lifelong psychotic disorder with a poor prognosis. National guidelines in the UK recommend the provision of cognitive behavioral therapy (CBT) to all those suffering with psychotic disorders, but there is a lack of trained therapists in the UK able to provide such a treatment. Developing high quality automated technologies that can serve as an adjunct to conventional CBT should enhance the provision of this therapy, and increase the efficiency of the therapists in practice. The latter will occur by enabling alternate professionals to aid in the delivery of therapy, to enable behavioral experiments to be conducted in the clinic, and for sessions to be recorded and re-played such that the patient can deliver therapy to him or herself. As such the system will enable patients to become experts in, and providers of, their own treatment and decrease the number of sessions needed to be led by a trained CBT therapist. A key feature of any such system is the level of realism required to ensure a compelling session in which the user is not adversely affected by the system itself. This paper presents a high-fidelity virtual environment to help better understand the environmental triggers for psychosis.

Background: It is commonly assumed that there are clear lines of demarcation between anxiety and depressive disorders on the one hand and psychosis on the other. Recent evidence, however, suggests that this principle may be in need of updating. Methods: Depressive and/or anxiety disorders, with no previous history of psychotic disorder, were examined for the presence of psychotic symptoms in a representative community sample of adolescents and young adults (Early Developmental Stages of Psychopathology study; n = 3021). Associations and consequences of psychotic symptomatology in the course of these disorders were examined in terms of demographic distribution, illness severity, onset of service use, and risk factors. Results: Around 27% of those with disorders of anxiety and depression displayed one or more psychotic symptoms, vs 14% in those without these disorders (OR 2.23, 95% CI 1.89–2.66, P cannabis use (P < .0009), and any drug use (P < .0008). Conclusion: Copresence of psychotic symptomatology in disorders of anxiety and depression is common and a functionally and etiologically highly relevant feature, reinforcing the view that psychopathology is represented by a network or overlapping and reciprocally impacting dimensional liabilities.

Schizoaffective disorder is a complex illness for which optimal treatment is not well established. Results of the first controlled, relapse-prevention study of paliperidone palmitate once-monthly injectable (paliperidone monthly) in schizoaffective disorder are presented. The study was conducted between September 20, 2010, and October 22, 2013. Patients with schizoaffective disorder (confirmed by the Structured Clinical Interview for DSM-IV Axis I Disorders) experiencing acute exacerbation of psychotic and depressive/manic symptoms were stabilized with paliperidone monthly as monotherapy or as adjunctive therapy to mood stabilizers or antidepressants and randomly assigned (1:1) to paliperidone monthly or placebo in a 15-month, double-blind, relapse-prevention phase. Randomization was stratified by administration as monotherapy or adjunctive therapy and by study center. The primary endpoint was time to relapse. 334 patients were evaluated. Paliperidone monthly significantly delayed time to relapse for psychotic, depressive, and manic symptoms compared with placebo (P paliperidone monthly. For monotherapy, relapse risk was 3.38 times greater with placebo (P = .002), and for adjunctive treatment it was 2.03 times greater with placebo (P = .021). Paliperidone monthly was superior to placebo in maintaining functioning as measured by the Personal and Social Performance scale (P = .014, mixed-model repeated-measures analysis). The most common adverse events (placebo, paliperidone monthly) were increased weight (4.7%, 8.5%), insomnia (7.1%, 4.9%), schizoaffective disorder (5.9%, 3.0%), headache (3.5%, 5.5%), and nasopharyngitis (3.5%, 5.5%). Incidence of any extrapyramidal-related adverse event was 7.1% for placebo and 8.5% for paliperidone monthly. Paliperidone monthly as monotherapy or adjunctive therapy significantly delayed psychotic, depressive, and/or manic relapses; reduced their risk; and better maintained functioning in patients with schizoaffective disorder

The aim of the TAILOR trial is to investigate the effect of closely monitored tapering/discontinuation versus maintenance therapy with antipsychotic medication in patients with newly diagnosed schizophrenia or persistent delusional disorder and with minimum 3 months' remission of psychotic symptoms. Two hundred and fifty patients will be included from the psychiatric early intervention program, OPUS, in two regions in Denmark. Inclusion criteria are: ICD-10 diagnoses schizophrenia (F20, except F20.6) or persistent delusional disorder (F22), minimum 3 months' remission of psychotic symptoms and in treatment with antipsychotic medication (except clozapine). The patients will be randomized to maintenance therapy or tapering/discontinuation with antipsychotic medication in a 1-year intervention. The tapering/discontinuation group will be using a smartphone application to monitor early warning signs of psychotic relapse. Patients will be assessed at baseline, 1-, 2- and 5-year follow-up regarding psychotic and negative symptoms, side-effects of antipsychotic medication, social functioning, cognitive functioning, perceived health status, patient satisfaction, substance and alcohol use, sexual functioning and quality of life. The primary outcome will be remission of psychotic symptoms and no antipsychotic medication after 1 year. Secondary outcome measures will include: co-occurrence of remission of psychotic symptoms and 0-1-mg haloperidol equivalents of antipsychotic medication after 1-year intervention; antipsychotic dose; antipsychotic side effects; negative symptoms; social functioning; cognitive functioning; and patient satisfaction. Exploratory outcomes will include remission, clinical recovery, substance and alcohol use, sexual functioning, quality of life, self-beliefs of coping and user experience of support from health workers. Safety measures will include death, admissions to psychiatric hospital, severe self-harm and psychotic relapses. The TAILOR trial

Methylphenidate is one of the classic amphetamines which can cause or exacerbate psychotic symptoms in schizophrenia patients. In this paper, a young man is presented with injection of methylphenidate tablets with acute cellulitis due to this injection and the related symptoms. In the first hospitalization and after recovery from psychotic disorder due to tablet injections, he was under treatment with anti-psychotics because of other symptoms related to schizophrenia. Although the patient was regularly under schizophrenic medication after discharge, he was hospitalized twice more due to psychotic symptoms that appeared after injecting methylphenidate. This report shows psychotic symptoms in schizophrenic patients after injecting methylphenidate. These symptoms cannot be prevented even by anti-psychotic medication of background disease. This case shows the existence of two kinds of psychoses, functional (due to schizophrenia) and organic psychoses (due to methylphenidate use) in the same patient.

Self-stigma is highly prevalent in schizophrenia and can be seen as an important factor leading to low self-esteem. It is however unclear how psychological factors and actual adverse events contribute to self-stigma. This study empirically examines how symptom severity and the experience of being victimized affect both self-stigma and self-esteem. Persons with a schizophrenia spectrum disorder (N = 102) were assessed with a battery of self-rating questionnaires and interviews. Structural equation modelling (SEM) was subsequently applied to test the fit of three models: a model with symptoms and victimization as direct predictors of self-stigma and negative self-esteem, a model with an indirect effect for symptoms mediated by victimization and a third model with a direct effect for negative symptoms and an indirect effect for positive symptoms mediated by victimization. Results showed good model fit for the direct effects of both symptoms and victimization: both lead to an increase of self-stigma and subsequent negative self-esteem. Negative symptoms had a direct association with self-stigma, while the relationship between positive symptoms and self-stigma was mediated by victimization. Our findings suggest that symptoms and victimization may contribute to self-stigma, leading to negative self-esteem in individuals with a schizophrenia spectrum disorder. Especially for patients with positive symptoms victimization seems to be an important factor in developing self-stigma. Given the burden of self-stigma on patients and the constraining effects on societal participation and service use, interventions targeting victimization as well as self-stigma are needed.

Cannabis use has been reported to be associated with an earlier onset of symptoms in patients with first-episode psychosis, and a worse outcome in those who continue to take cannabis. In general, studies have concentrated on symptoms of psychosis rather than mania. In this study, using a longitudinal design in a large naturalistic cohort of patients with first-episode psychosis, we investigated the relationship between cannabis use, age of presentation to services, daily functioning, and positive, negative and manic symptoms. Clinical data on 502 patients with first-episode psychosis were collected using the MiData audit database from seven London-based Early Intervention in psychosis teams. Individuals were assessed at two time points--at entry to the service and after 1 year. On each occasion, the Positive and Negative Syndrome Scale, Young Mania Rating Scale and Global Assessment of Functioning Scale disability subscale were rated. At both time points, the use of cannabis and other drugs of abuse in the 6 months preceding each assessment was recorded. Level of cannabis use was associated with a younger age at presentation, and manic symptoms and conceptual disorganization, but not with delusions, hallucinations, negative symptoms or daily functioning. Cannabis users who reduced or stopped their use following contact with services had the greatest improvement in symptoms at 1 year compared with continued users and non-users. Continued users remained more symptomatic than non-users at follow-up. Effective interventions for reducing cannabis use may yield significant health benefits for patients with first-episode psychosis.

This study investigated how severely depressed individuals experienced the relationship between psychotic symptoms and suicidal ideation and behavior. Semi-structured qualitative interviews were conducted with a purposive sample of nine inpatients from a psychiatric university hospital between September 2012 and May 2013 fulfilling diagnostic criteria for a psychotic depressive episode as part of a unipolar or bipolar disorder. Analysis was conducted using systematic text condensation. Participants experienced (1) being directed to perform impulsive potentially fatal actions, (2) feeling hounded to death, (3) becoming trapped in an inescapable darkness, and (4) being left bereft of mental control. They described how impulsivity directed by delusions and hallucinations resulted in unpredictable actions with only moments from decision to conduct. Suicide was seen as an escape not only from life problems but also from psychotic experiences and intense anxiety. Participants reported being in a chaotic state, unable to think rationally or anticipate the consequences of their actions. Their ability to identify and communicate psychotic symptoms and suicidal ideation and behavior was compromised, leaving them to struggle alone with these terrifying experiences. Suicide risk assessments based on verbal reports from individuals with psychotic depression may not always be valid due to potential impulsivity and underreporting of suicidal ideation. It may be important for clinicians to explore the delusional content of such patients' experiences to assess the possibility of suicide as a result of shame, guilt, remorse, or altruistic intentions to save others from harm.
Full Text Available 22q11.2 Microdeletion Syndrome (22q11DS is a highly penetrant genetic mutation associated with a significantly increased risk for psychosis. Aberrant neurodevelopment may lead to inappropriate neural circuit formation and cerebral dysconnectivity in 22q11DS, which may contribute to symptom development.

Spontaneous EEG signal can be parsed into sub-second periods of stable functional states (microstates) that assumingly correspond to brief large scale synchronization events. In schizophrenia, a specific class of microstate (class "D") has been found to be shorter than in healthy controls and to be correlated with positive symptoms. To explore potential new treatment options in schizophrenia, we tested in healthy controls if neurofeedback training to self-regulate microstate D presence is feasible and what learning patterns are observed. Twenty subjects underwent EEG-neurofeedback training to up-regulate microstate D presence. The protocol included 20 training sessions, consisting of baseline trials (resting state), regulation trials with auditory feedback contingent on microstate D presence, and a transfer trial. Response to neurofeedback was assessed with mixed effects modelling. All participants increased the percentage of time spent producing microstate D in at least one of the three conditions (p neurofeedback training. Given that microstate D has been related to attentional processes, this result provides further evidence that the training was to some degree specific for the attentional network. We conclude that microstate-neurofeedback training proved feasible in healthy subjects. The implementation of the same protocol in schizophrenia patients may promote skills useful to reduce positive symptoms by means of EEG-neurofeedback.

It is important that mental health nurses meet the safety, security and care needs of persons suffering from psychotic illness to enhance these persons' likelihood of feeling better during their time in acute psychiatric wards. Certain persons in care describe nurses' mental health care as positive, whereas others report negative experiences and express a desire for improvements. There is limited research on how persons with psychotic illness experience nurses' mental health care acts and how such acts help these persons feel better. Therefore, the aim of this study was to explore, describe and understand how the mental health nurses in acute psychiatric wards provide care that helps persons who experienced psychotic illness to feel better, as narrated by these persons. This study had a qualitative design; 12 persons participated in qualitative interviews. The interviews were transcribed, content analysed and interpreted using Martin Buber's concept of confirmation. The results of this study show three categories of confirming mental health care that describe what helped the participants to feel better step-by-step: first, being confirmed as a person experiencing psychotic illness in need of endurance; second, being confirmed as a person experiencing psychotic illness in need of decreased psychotic symptoms; and third, being confirmed as a person experiencing psychotic illness in need of support in daily life. The underlying meaning of the categories and of subcategories were interpreted and formulated as the theme; confirming mental health care to persons experiencing psychotic illness. Confirming mental health care acts seem to help persons to feel better in a step-wise manner during psychotic illness. Nurses' openness and sensitivity to the changing care needs of persons who suffer from psychotic illness create moments of confirmation within caring acts that concretely help the persons to feel better and that may enhance their health. The results show the

Research suggests that tobacco smokers may develop psychosis at an earlier age than non-smokers, with effects on psychotic symptoms. We aimed to test the difference in age of onset of psychosis between smokers and non-smokers. Self-report data were collected from smokers and non-smokers in a population of first-episode psychosis patients. Out-patient first-episode psychosis programme in Santander (Cantabria), Spain. Three hundred and ninety-seven patients (226 male, 171 female) who agreed to take part between 2001 and 2011. Age of onset of psychosis, age of smoking initiation, demographics, family history of psychosis and cannabis use were collected by self-report. Kaplan-Meier analysis showed that smokers had a significantly lower mean age of psychosis onset [smokers = 27.4 (± 8.1) years, non-smokers = 30.5 (± 9.9) years] than non-smokers (χ 2 (1) = 11.72, P = 0.001). The Cox proportional hazard model showed no significant difference in the age of psychosis onset between smokers and non-smokers adjusted for covariates [hazard ratio (HR) = 1.034, 95% confidence interval (CI) = 0.828-1.291]. Age of psychosis onset was predicted significantly by cannabis use (HR = 2.073, 95% CI = 1.633-2.633) and gender (HR = 1.706, 95% CI = 1.363-2.135). Smokers do not appear to have a significantly earlier age of psychosis onset than non-smokers after taking into account cannabis use and gender. © 2016 Society for the Study of Addiction.

An evidence base for the treatment of mania and bipolar depression with psychotic symptoms is lacking. Nevertheless, clinicians may have a preference for treating episodes of bipolar disorder with or without psychotic symptoms in different ways, which is likely to reflect notions of differential efficacy of treatments between these subtypes. This study aimed to investigate whether the psychopharmacological treatment of psychotic and non-psychotic episodes of mania and bipolar depression, respectively, differs in clinical practice. We conducted a register-based study assessing the psychopharmacological treatment of all individuals receiving their first diagnosis of mania or bipolar depression between 2010 and 2012. The psychopharmacological treatment within 3 months following the time of diagnosis was considered. Potential differences in psychopharmacological treatment between the psychotic and non-psychotic subtypes of mania and bipolar depression, respectively, were investigated by means of Pearson's χ 2 test and logistic regression adjusted for sex and age at diagnosis of bipolar disorder. A total of 827 patients were included in the analyses. The adjusted odds ratio (aOR) for treatment with an antipsychotic was 1.71 (95% confidence interval [CI]: 1.18-2.48, Pbipolar depression. The aOR for treatment with the combination of an antipsychotic and an anticonvulsant was 1.60 (95% CI: 1.06-2.43, Pbipolar psychotic depression. It would be of interest to conduct studies evaluating whether antipsychotics represent the superior pharmacological treatment for psychotic mania and psychotic bipolar depression. © 2017 John Wiley & Sons A/S.

have suggested a link between dysregulation of the HPA axis and psychotic symptoms both through abnormal basal levels of cortisol and flattened reactivity to social stress. Imaging results suggest indirect modifications, including abnormal pituitary or hippocampal volume. Several factors dysregulating the HPA axis have also been highlighted, such as consumption of drugs (i.e. cannabis), childhood trauma or genetic factors (such as COMT, or MTHFR variants). Psychological stress induces subcortical dopaminergic activation attributable to hypothalamic-pituitary-adrenal (HPA) axis dysregulation. This dysregulation is present in the prodromal phase (UHR) in patients who have experienced a first psychotic episode (FEP) and in siblings of schizophrenic patients. Stress dysregulation is a plausible hypothesis to understand the psychosis onset. The effect of stress on brain pathways could participate to the mechanisms underlying the onset of psychotic symptoms, both as a precipitating factor and as a marker of a predisposing vulnerability. This dysregulation fits into the gene x environment model: in subjects with genetic predispositions, stressful environmental factors can modify biological pathways implicated in psychiatric disorders, promoting the emergence of symptoms. However, many confounding factors obscure the literature, and further studies are needed in schizophrenic patients, UHR and FEP patients to clarify the precise role of stress in psychotic transition. Identification of stress biomarkers could help diagnosis and prognosis, and pave the way for specific care strategies based on stress-targeted therapies. Copyright © 2016 L’Encéphale, Paris.

Schizophrenia, schizoaffective disorder, and psychotic bipolar disorder overlap with regard to symptoms, structural and functional brain abnormalities, and genetic risk factors. Neurobiological pathways connecting genes to clinical phenotypes across the spectrum from schizophrenia to psychotic bipolar disorder remain largely unknown. We examined the relationship between structural brain changes and risk alleles across the psychosis spectrum in the multi-site Bipolar-Schizophrenia Network for Intermediate Phenotypes (B-SNIP) cohort. Regional MRI brain volumes were examined in 389 subjects with a psychotic disorder (139 schizophrenia, 90 schizoaffective disorder, and 160 psychotic bipolar disorder) and 123 healthy controls. 451,701 single-nucleotide polymorphisms were screened and processed using parallel independent component analysis (para-ICA) to assess associations between genes and structural brain abnormalities in probands. 482 subjects were included after quality control (364 individuals with psychotic disorder and 118 healthy controls). Para-ICA identified four genetic components including several risk genes already known to contribute to schizophrenia and bipolar disorder and revealed three structural components that showed overlapping relationships with the disease risk genes across the three psychotic disorders. Functional ontologies representing these gene clusters included physiological pathways involved in brain development, synaptic transmission, and ion channel activity. Heritable brain structural findings such as reduced cortical thickness and surface area in probands across the psychosis spectrum were associated with somewhat distinct genes related to putative disease pathways implicated in psychotic disorders. This suggests that brain structural alterations might represent discrete psychosis intermediate phenotypes along common neurobiological pathways underlying disease expression across the psychosis spectrum.

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) was published by the American Psychiatric Association (APA) in 2013, and the Work Group on the Classification of Psychotic disorders (WGPD), installed by the World Health Organization (WHO), is expected to publish the new chapter about schizophrenia and other primary psychotic disorders in 2017. We reviewed the available literature to summarize the major changes, innovations, and developments of both manuals. If available and possible, we outline the theoretical background behind these changes. Due to the fact that the development of ICD-11 has not yet been completed, the details about ICD-11 are still proposals under ongoing revision. In this ongoing process, they may be revised and therefore have to be seen as proposals. DSM-5 has eliminated schizophrenia subtypes and replaced them with a dimensional approach based on symptom assessments. ICD-11 will most likely go in a similar direction, as both manuals are planned to be more harmonized, although some differences will remain in details and the conceptual orientation. Next to these modifications, ICD-11 will provide a transsectional diagnostic criterion for schizoaffective disorders and a reorganization of acute and transient psychotic and delusional disorders. In this manuscript, we will compare the 2 classification systems.

Congenital or early life infection with Toxoplasma gondii has been implicated in schizophrenia aetiology. Childhood cat ownership has been hypothesized as an intermediary marker of T. gondii infection and, by proxy, as a risk factor for later psychosis. Evidence supporting this hypothesis is, however, limited. We used birth cohort data from the Avon Longitudinal Study of Parents and Children (ALSPAC) to investigate whether cat ownership in pregnancy and childhood (ages 4 and 10 years) was associated with psychotic experiences (PEs) in early (age 13, N = 6705) and late (age 18, N = 4676) adolescence, rated from semi-structured interviews. We used logistic regression to examine associations between cat ownership and PEs, adjusting for several sociodemographic and socioeconomic factors, household characteristics and dog ownership. Missing data were handled via multiple imputation. Cat ownership during pregnancy was not associated with PEs at age 13 years [adjusted odds ratio (OR) 1.15, 95% confidence interval (CI) 0.97-1.35] or 18 years (OR 1.08, 95% CI 0.86-1.35). Initial univariable evidence that cat ownership at ages 4 and 10 years was associated with PEs at age 13 years did not persist after multivariable adjustment (4 years: OR 1.18, 95% CI 0.94-1.48; 10 years: OR 1.12, 95% CI 0.92-1.36). There was no evidence that childhood cat ownership was associated with PEs at age 18 years. While pregnant women should continue to avoid handling soiled cat litter, given possible T. gondii exposure, our study strongly indicates that cat ownership in pregnancy or early childhood does not confer an increased risk of later adolescent PEs.

Full Text Available Leuprolide acetate is usually used in the treatment of advanced prostate cancer. The adverse events associated with administration of leuprolide acetate include fatigue, hot flashes, loss of libido, impotence, and depression. These side effects can be treated conservatively. Acute manic and psychiatric symptoms following leuprolide acetate injection are very rare. Few case reports have been published documenting these symptoms. Here, we describe the case of a 62-year-old male with metastatic prostate cancer, who developed acute manic and psychiatric symptoms 2 months after subcutaneous leuprolide acetate injection. These symptoms were relieved after administration of neuroleptic drugs, such as risperidone. Administration of leuprolide acetate was eventually stopped. The exact mechanism causing the manic and psychiatric adverse events is unclear. Some experts have theorized that estrogen withdrawal following leuprolide acetate therapy may induce psychiatric symptoms. Manic episodes may arise from a deficit in central serotonergic neurotransmission. Based on these hypotheses, risperidone, lithium, and some anticonvulsants, such as divalproex sodium and carbamazepine, have been used effectively in the treatment and prophylaxis of manic episodes. Although psychiatric adverse events are rare following administration of leuprolide acetate, clinicians should be aware of the possibility.

Full Text Available It is becoming increasingly clear that psychosis occurs along a continuum. At the high end are formal psychotic disorders such as schizophrenia, and at the low-end are individuals who experience occasional psychotic symptoms, but are otherwise healthy (non-clinical psychosis, NCP. Schizophrenia has been shown to be marked by altered patterns of connectivity between brain regions, but it is not known if such dysconnectivity exists in NCP. In the current study we used functional magnetic resonance imaging (fMRI to compare resting-state functional connectivity in NCP individuals (n = 25 and healthy controls (n = 27 for four brain networks of interest (fronto-parietal, cingulo-opercular, default mode, and cerebellar networks. NCP individuals showed reduced connectivity compared to controls between regions of the default mode network and frontal regions, and between regions in all of the networks and the thalamus. NCP individuals showed greater connectivity compared to controls within regions of frontal control networks. Further, positive symptom scores in NCP individuals were positively correlated with connectivity between the cingulo-opercular network and the visual cortex, and were negatively correlated with connectivity between the cerebellar network and the posterior parietal cortex and dorsal premotor cortex. Connectivity was not correlated with positive symptom scores in controls. Taken together, these findings demonstrate that a spectrum of abnormal connectivity underlies the psychosis continuum, and that individuals with sub-clinical psychotic experiences represent a key population for understanding pathogenic processes.
Full Text Available Objective: Some authors report that aggressive behaviour in schizophrenia is of heterogeneous sources, for example, aggression may be an impulsive action and even deliberate behaviour designed to intimidate others. Violence and aggressive behaviour may also be associated with psychotic experiences, such as delusions or hallucinations. The aim of this study was to explore the relationship between psychotic experiences and the intensiveness of hostility and aggression in patients with paranoid schizophrenia. Material and method: Seventy outpatients (35 men and 35 women with paranoid schizophrenia were examined. Relevant scales, subscales and indices of the Polish version of Minnesota Multiphasic Personality Inventory (MMPI were used. Results: The analysis of correlation and the factor analysis revealed a number of statistically significant correlations between the scores of the scales assessing psychotic experiences and those assessing the intensiveness of hostility and aggression. Conclusions: The results of this study confirm the presence of a number of relationships between psychotic experiences and felt hostility and aggression. Psychotic symptoms and indices of aggressiveness created five factors: “psychoticism,” “hostility,” “psychopathic aggression,” “poignancy,” “persecutory ideas.” Important for the felt hostility and aggressiveness in patients turned out to be experienced anxiety about their mental health because of the sense of the unreality of what is going on and because of the sense of alienation of their own thoughts. Another important factor turned out to be a sense of being wronged by life, misunderstood by others, and the belief that people have a grudge and try to harm. In contrast, characteristics, attitudes and behaviour which are the opposite of paranoid disorders, i.e. faith in people and optimistic attitude towards them, are an important factor for the inhibition of aggression.

The existence of an aphasia-like language disorder in psychotic speech has been the subject of much debate. This paper argues that a discrete language disorder could be an important cause of the disturbance seen in psychotic speech. A review is presented of classical clinical descriptions and experimental studies that have explored the similarities between psychotic language impairment and aphasic speech. The paper proposes neurolinguistic tasks which may be used in future studies to elicit subtle language impairments in psychotic speech. The usefulness of a neurolinguistic model for further research in the aetiology and treatment of psychosis is discussed.

Full Text Available Background: Cognitive biases play an important role in the formation and maintenance of delusions. These biases are indicators of a weak reflective mind, or reduced engaging in reflective and deliberate reasoning. In three experiments, we tested whether a bias to accept non-sense statements as profound, treat metaphorical statements as literal, and suppress intuitive responses is related to psychotic-like experiences.Methods: We tested deliberate reasoning and psychotic-like experiences in the general population and in patients with a former psychotic episode. Deliberate reasoning was assessed with the bullshit receptivity scale, the ontological confabulation scale and the cognitive reflection test (CRT. We also measured algorithmic performance with the Berlin numeracy test and the wordsum test. Psychotic-like experiences were measured with the Community Assessment of Psychic Experience (CAPE-42 scale.Results: Psychotic-like experiences were positively correlated with a larger receptivity toward bullshit, more ontological confabulations, and also a lower score on the CRT but not with algorithmic task performance. In the patient group higher psychotic-like experiences significantly correlated with higher bullshit receptivity.Conclusion: Reduced deliberate reasoning may contribute to the formation of delusions, and be a general thinking bias largely independent of a person's general intelligence. Acceptance of bullshit may be facilitated the more positive symptoms a patient has, contributing to the maintenance of the delusions.

Misidentification phenomena, including the delusion of 'imposters' named after Joseph Capgras, occur in various major psychiatric and neurological disorders but have rarely been studied systematically in broad samples of modern patients. This study investigated the prevalence and correlated clinical factors of Capgras' phenomenon in a broad sample of patient-subjects with first-lifetime episodes of psychotic affective and nonaffective disorders. We evaluated 517 initially hospitalized, first-episode psychotic-disorder patients for the prevalence of Capgras' phenomenon and its association with DSM-IV-TR diagnoses including schizophreniform, brief psychotic, unspecified psychotic, delusional, and schizoaffective disorders, schizophrenia, bipolar-I disorder and major depression with psychotic features, and with characteristics of interest including antecedent psychiatric and neurological morbidity, onset type and presenting psychopathological phenomena, using standard bivariate and multivariate statistical methods. Capgras' syndrome was identified in 73/517 (14.1%) patients (8.2-50% across diagnoses). Risk was greatest with acute or brief psychotic disorders (schizophreniform psychoses 50%, brief psychoses 34.8%, or unspecified psychoses 23.9%), intermediate in major depression (15%), schizophrenia (11.4%) and delusional disorder (11.1%), and lowest in bipolar-I (10.3%) and schizoaffective disorders (8.2%). Associated were somatosensory, olfactory and tactile hallucinations, Schneiderian (especially delusional perception), and cycloid features including polymorphous psychotic phenomena, rapidly shifting psychomotor and affective symptoms, pananxiety, ecstasy, overconcern with death, and perplexity or confusion, as well as rapid onset, but not sex, age, abuse history, dissociative features, or indications of neurological disorders. Capgras' syndrome was prevalent across a broad spectrum of first-episode psychotic disorders, most often in acute psychoses of rapid onset.

Background Misidentification phenomena, including the delusion of “imposters” named after Joseph Capgras, occur in various major psychiatric and neurological disorders but have rarely been studied systematically in broad samples of modern patients. This study investigated the prevalence and correlated clinical factors of Capgras phenomenon in a broad sample of patient-subjects with first-lifetime episodes of psychotic affective and non affective disorders. Methods We evaluated 517 initially hospitalized, first-episode psychotic-disorder patients for prevalence of Capgras phenomenon and its association with DSM-IV-TR diagnoses including schizophreniform, brief psychotic, unspecified psychotic, delusional, and schizoaffective disorders, schizophrenia, bipolar-I disorder and major depression with psychotic features, and with characteristics of interest including antecedent psychiatric and neurological morbidity, onset-type and presenting psychopathological phenomena, using standard bivariate and multivariate statistical methods. Results Capgras syndrome was identified in 73/517 (14.1%) patients (8.2%–50% across diagnoses). Risk was greatest with acute or brief psychotic disorders (schizophreniform [50%], brief [34.8%], or unspecified [23.9%] psychoses), intermediate in major depression (15%), schizophrenia (11.4%) and delusional disorder (11.1%), and lowest in bipolar-I (10.3%) and schizoaffective disorders (8.2%). Associated were somatosensory, olfactory and tactile hallucinations, Schneiderian (especially delusional perception), and cycloid features as described by Perris and Brockington including polymorphous psychotic phenomena, rapidly shifting psychomotor and affective symptoms, pan-anxiety, ecstasy, over-concern with death, and perplexity or confusion, as well as rapid-onset, but not sex, age, abuse-history, dissociative features, or indications of neurological disorders. Conclusions Capgras syndrome was prevalent across a broad spectrum of first
Full Text Available Over the past decade, major cities in China have suffered from severe air pollution, which is also known as smog. Despite lay considerations that smog might pose risks for psychopathology, it remains unknown whether it is only linked to affective psychopathology or to a broader range of symptomologies. Moreover, whether individual differences in emotion regulation, a transdiagnostic risk factor for psychopathology, would influence the magnitude of pollution-induced symptoms is not well understood. Using a longitudinal design, the current study measured trait emotion regulation and psychopathological symptoms in a sample of university students at Time 1 (without smog, N = 120 and then reassessed for psychopathology at Time 2 (after acute exposure to smog for 1 week, N = 102. The results showed that participants had higher levels of positive symptom distress, obsessive-compulsive symptoms, interpersonal sensitivity, depression, and psychoticism at Time 2. Moreover, reappraisal is negatively associated with smog-induced elevations in psychopathological symptoms only when participants rely heavily on suppression. We discuss the implications of this investigation for both intervention efforts and future work on the contextual factors surrounding the deployment of emotion regulation strategies.

Cycloid psychosis is a psychiatric disorder known for about 100 years. This disorder is at present partly and simplified represented in the ICD-10. Over a period of 15 months, 139 consecutively acutely admitted psychotic patients were assessed, by means of different diagnostic instruments, in order to investigate the prevalence and the symptom profile of cycloid psychoses. In addition, the concordance between the diagnoses cycloid psychosis, brief psychotic disorder, and acute polymorphic psychotic disorder with or without symptoms of schizophrenia was calculated. Cycloid psychoses were present in 13% of the patients. There was a significant but small overlap with the DSM brief psychotic disorder and the ICD acute polymorphic psychotic disorder. This study demonstrates that cycloid psychoses can be identified with the proper diagnostic instruments in a proportion that is also found in other studies. Since this type of psychosis entails a distinct prognosis and may require a specific treatment, its identification is of clinical importance. Limitations are the nature of the psychiatric facility with an inherent bias in the selection of patients and the lack of a long-term evaluation. Copyright 2004 S. Karger AG, Basel

Distinguishing between a primary psychotic disorder with concurrent substance abuse (PPD+SA) and a substance-induced psychotic disorder (SIPD) can be diagnostically challenging. We aimed to determine if these two diagnoses are clinically distinct, particularly in relation to psychopathology. In addition, we aimed to examine the specific clinical features of cannabis-induced psychotic disorder (CIPD) as compared to primary psychotic disorder with concurrent cannabis abuse (PPD+CA) and also to SIPD associated with any substance. A systematic review of SIPD literature using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Using strict inclusion criteria, a total of six studies examining SIPD were included in the review (two of which only considered psychosis induced by cannabis alone). The findings did not reveal many consistent differences in psychopathology. However, we did find that that compared to PPD+SA, individuals with SIPD have a weaker family history of psychotic disorder; a greater degree of insight; fewer positive symptoms and fewer negative symptoms; more depression (only in CIPD) and more anxiety. There remains a striking paucity of information on the psychopathology, clinical characteristics and outcome of SIPD. Our review highlights the need for further research in this area.

The association between borderline personality disorder and the ultra high risk (UHR) for psychosis state is unclear. The following study aimed to investigate the type of attenuated psychotic symptoms and prevalence of borderline personality pathology in a sample of UHR young people. Additionally, the study aimed to explore whether borderline personality pathology influenced the transition rate to psychosis. Medical records from Orygen Youth Health between 2007 and 2009 were examined. There were 180 patients who met UHR criteria and were included for analysis. Most patients were females (62.8%) and age ranged from 15 to 24 years. A quarter (25.2%) of UHR patients endorsed items consistent with borderline personality pathology. UHR patients with borderline personality pathology experienced a range of attenuated psychotic symptoms and could not be statistically differentiated from UHR patients with less significant or without borderline personality pathology. Borderline personality pathology did not increase or decrease the risk of developing a psychotic disorder. The absence of depression was the only predictor of psychosis. Many UHR patients present with concurrent borderline personality features. The psychotic experiences reported by UHR patients with borderline personality features were not limited to paranoid ideation, supporting the idea that borderline personality disorder may include a wider range of psychotic symptoms than previously thought. It is further possible that the psychotic symptoms experienced in this group could also be indicative of an emerging psychotic disorder. © 2015 Wiley Publishing Asia Pty Ltd.

Impairments in social cognition are now recognized as core illness features in psychotic and affective disorders. Despite the significant disability caused by social cognitive abnormalities, treatments for this symptom dimension are lacking. Here, we describe the evidence demonstrating abnormalities in social cognition in schizophrenia, major depressive disorder, and bipolar disorder, as well as the neurobiology of social cognition including the role of oxytocin. We then review clinical trials of oxytocin administration in psychotic and affective disorders and the impact of this agent on social cognition. To date, several studies have demonstrated that oxytocin may improve social cognition in schizophrenia; too few studies have been conducted in affective disorders to determine the effect of oxytocin on social cognition in these disorders. Future work is needed to clarify which aspects of social cognition may be improved with oxytocin treatment in psychotic and affective disorders. Copyright © 2014 Elsevier B.V. and ECNP.

Full Text Available A lot of people live situations of mental sickness, from psychotic character, that can cause sufferingboth for the sick and his family. We believe that try this situation means to live with limitations and wearings in thefamiliar everyday, what makes difficult the living with the psychotic person. Considering these aspects, thisresearch has the purpose of knowing the familiar perception about his living with a psychotic bearer person. It isabout a qualitative, explorative and descriptive study, developed in a northwest city of Rio Grande do Sul state,called Ijuí. The people of the investigation are composed of five psychotics parents, which frequent the socioterapygroup in Gloria district. The information collection happened trough open interviews, recorded and wrote out at all.The analysis of the obtained data followed MINAYOs (2002 methodological proposition. By the containedinformation in the studs social actors declarations, emerged three thematic with a similar nucleus of thoughts. Onfirst thematic, we discussed about the difficulties faced by the familiars in the living with the psychotic in themoment he has the acute symptoms. On the second thematic, we talked about the medical question as bring atherapeutic element that helps the mental sick to keep stable., becoming better the familiars life. The third thematicshows the family conception about mental sickness. With this research we concluded that the living with a mentalsick person is taxing for the familiar and, sometimes, there are difficulties to understand the symptoms showed bythe sick person. Besides that, the family considers the medication one of the most important possibilities ofintervention in the psychotics therapy, what is reinforced by the health team that leads with these people.

BACKGROUND: Severe unipolar depression is associated with increased risk of suicide, but it remains unknown whether the same risk factors are present in the non-psychotic (non-PD) and psychotic (PD) subtypes respectively. Therefore, this study aimed to identify risk factors for suicide in non......-PD and PD separately, and to investigate if the presence of psychotic symptoms is an independent risk factor for suicide in severe depression. METHODS: This register-based, nationwide, historical prospective cohort study used logistic regression analyses to ascertain risk factors for suicide among all...... adults diagnosed with severe depression at Danish psychiatric hospitals between January 1, 1994 and December 31, 2010. The risk for suicide was expressed as adjusted odds ratios (AOR). RESULTS: A total of 34,671 individuals with severe depression (non-PD: n=26,106 and PD: n=12,101) were included...

Background/Aims Previous studies point to an association between childhood sexual abuse (CSA) and auditory hallucinations (AH). However, methodological issues limit the strength of these results. Here we compared childhood abuse between psychotic disorder patients and healthy control subjects using a reliable measure of abuse, and assessed the relationship between CSA and AH. Methods 114 psychotic disorder patients and 81 healthy control subjects were administered the Structured Clinical Interview of the DSM-IV (SCID) and the Childhood Trauma Questionnaire (CTQ). We compared the severity of abuse between groups, and tested the relationship between different types of childhood abuse and specific psychotic symptoms. Results Psychotic patients reported more childhood abuse than controls (phallucination other than AH or of any form of delusion. Conclusions These results suggest that childhood abuse, especially childhood sexual abuse, shapes the phenotype of psychotic disorders by conferring a specific risk for AH. PMID:23815887

Schizophrenia is a clinically heterogeneous disorder. A multifactorial structure of this syndrome has been described in previous reports. The aim of this study was to evaluate what are the possible diagnostic categories in patients having acute psychotic symptoms, studying their clinical characteristics in a cross-sectional study. An instrument for measuring psychotic symptoms was created using previous scales (SANS, SAPS, BPRS, EMUN, Zung depression scale). Using as criteria statistical indexes and redundance of items, the initial instrument having 101 items has been reduced to 57 items. 232 patients with acute psychotic symptoms, in most cases schizophrenia, attending Clínica Nuestra Señora de la Paz in Bogotá and Hospital San Juan de Dios in Chía have been evaluated from April, 2008 to December, 2009. Multivariate statistical methods have been used for analyzing data. A six-factor structure has been found (Deficit, paranoid-aggressive, disorganized, depressive, bizarre delusions, hallucinations). Cluster analysis showed eight subtypes that can be described as: 1) bizarre delusions-hallucinations; 2) deterioration and disorganized behavior; 3) deterioration; 4) deterioration and paranoid-aggressive behavior; 5) bizarre delusions; 6) paranoia-anxiety- aggressiveness; 7) depressive symptoms and bizarre delusions; 8) paranoia and aggressiveness with depressive symptoms These subtypes allow a more exhaustive characterization that those included in standard classification schemes and should be validated in longitudinal studies.

Many social-cognitive models of psychotic-like symptoms posit a role for self-concept and aberrant salience. Previous work has shown that the interaction between aberrant salience and self-concept clarity is associated with self-reported psychotic-like experiences. In the current research with two structured interviews, the interaction between aberrant salience and self-concept clarity was found to be associated with interview-rated psychotic-like experiences. The interaction was associated with psychotic-like experiences composite scores, delusional ideation, grandiosity, and perceptual anomalies. In all cases, self-concept clarity was negatively associated with psychotic-like experiences at high levels of aberrant salience, but unassociated with psychotic-like experiences at low levels of aberrant salience. The interaction was specific to positive psychotic-like experiences and not present for negative or disorganized ratings. The interaction was not mediated by self-esteem levels. These results provide further evidence that aberrant salience and self-concept clarity play an important role in the generation of psychotic-like experiences.

For the vast majority of the scales, the clinical and psychometric validity had not been tested empirically. The only exception from this general tendency was the 11-item Psychotic Depression Assessment Scale (PDAS), which was developed specifically to assess the severity of PD. In PD, the PDAS represents the only empirically derived rating scale for the measurement of overall severity of illness. The PDAS should be considered in future studies of PD and in clinical practice. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.
Full Text Available Based on a case from the clinical praxis, the authors, adopting a neuropsyhological attitude, study and define the developmental disharmony of a psychotic type. They consider that the developmental disharmony of a psychotic type represents a global and profound destruction of structures and functions (motors, speech, emotions, cognition, socialization. The foundation thesis is that in basic of the disharmony developmental structure of the child. A “psychotic nucleus” is being created rather early in the age of Child’s development, with under pressure of the no favorable environmental factors leads to psychotic manifestation of the personality. The developmental disharmony of a psychotic type could have a various outcome. The child could manifest a progressive intellectual deterioration, to evolve in a direction of schizophrenic psychoses, to structure itself as a “Borderline” personality, while very rarely a relative normalization of the personality could occur. The authors promote the significance of early detection, qualitative diagnostics and adequate treatment by well educated and polyvalent, multidisciplinary expert team.

Bupropion, or amfebutamone, is an atypical antidepressant also used during tobacco cessation. From a structural standpoint, it resembles amphetamine drugs with psychostimulant effects, and endogenous monoamines. From a pharmacological standpoint, bupropion, and two of its most important active metabolites, inhibit dopamine and norepinephrine reuptake. It has recently been discovered that bupropion may act as a non-competitive cholinergic nicotinic receptor antagonist, and that it may inhibit the activation of reward systems triggered by nicotine. Buproprion's efficacy as a smoking cessation aid has been demonstrated by numerous clinical trials that have compared its effects with those of placebo and other nicotinic substitutes. In 2001, buproprion SR received marketing authorization in France as a smoking cessation aid, under the name ZYBAN®. Tobacco addiction indeed remains a major public health issue. Among patients with psychiatric conditions, chronic tobacco consumption is frequent. The development of non-nicotinic drugs may therefore enhance therapeutic possibilities. However, the psychotropic effects of these molecules should be taken into account. We have recently reported the case of a patient with schizoaffective disorder, who presented two acute bupropion-induced psychotic episodes. We have also undertaken an exhaustive bibliographical research on this subject. The aim of the present study is to present the information available to us, in order to suggest aetiopathogenic hypotheses and therapeutic proposals. The following databases were consulted on a regular basis, with no date restriction: Medline, Cochrane and Elsevier. The present study identified 22 cases of psychotic conditions associated with buproprion, as well as randomized and pharmacovigilance studies published in English, from December 1985 to November 2008. Since 2002, there have been three published case-reports on patients who underwent a tobacco cessation program. Psychotic disorders

Psychoactive substance abuse, which includes abuse of alcohol and street drugs, is common among first-episode psychosis patients, but the prevalence of cannabis abuse is particularly high. However, there have been very few reported studies concerning the occurrence of psychoactive substance abuse among first-episode psychotic individuals using standard toxicological testing. We study the prevalence of cannabis and alcohol abuse among first-psychoticepisode inpatients as well as compare the demographic, diagnostic, and psychopathological profiles of substance abusers versus nonusers. Subjects were recruited from the Jerusalem Mental Health Center between 2012 and 2014. Ninety-one consecutively admitted psychiatric patients diagnosed using the DSM-IV criteria with a first psychotic episode due to schizophrenia, schizophreniform disorder, bipolar disorder, brief psychotic episode, and psychosis NOS disorder entered the study. The diagnoses of schizophrenia (all types), psychosis NOS disorder, brief psychotic episode, and schizophreniform disorder were categorized as "only psychosis" and those of bipolar disorder manic episode with psychotic features (congruent and incongruent) and severe depression with psychotic features were categorized as "predominantly affective symptoms." Urine tests for tetrahydrocannabinol (THC) were performed during the first 48 hours of admission, and likewise self-report questionnaires were administered. Alcohol abuse and dependence were diagnosed by self-report. Of the 91 subjects in the study, 49 (53.8%) did not abuse any illegal psychoactive substance. Twenty patients (22%) abused only cannabis; 14 (15.4%) abused cannabis and another psychoactive substance; 54 (59.3%) of the subjects reported no alcohol abuse; 33 (36.3%) reported occasional drinking (between two and ten times a month); and 4 (4.4%) reported continuous repeated drinking (more than ten times a month). There was no correlation between the demographic characteristics and the

Social anxiety and eating disorders are highly comorbid. Several explanations for these high levels of comorbidity have been theorized. First, social anxiety might be a vulnerability factor for eating disorders. Second, eating disorders might be a vulnerability factor for social anxiety. Third, the two kinds of disorders may have common, shared psychological vulnerabilities. The current study (N = 300 undergraduate women) investigates a model of social anxiety and eating disorder symptoms that examines each of these possibilities across two time points (Time 1 and six months later). We do not find support for either social anxiety or eating disorder symptoms per se predicting each other across time. Instead, we find that some underlying vulnerabilities prospectively predict symptoms of both disorders, whereas other vulnerabilities are specific to symptoms of one disorder. Specifically we find that maladaptive perfectionism is a shared prospective vulnerability for social anxiety and eating disorder symptoms. Alternatively, we find that social appearance anxiety is specific for eating disorder symptoms, whereas high standards is specific for social anxiety symptoms. These data help clarify our understanding of how and why social anxiety and eating disorder symptoms frequently co-occur. PMID:27444957

Earlier studies indicated that personality characteristics contribute to symptomatic outcome in patients with psychotic disorders. The aim of the present study was to further explore this connection by examining the relationship between the Five-Factor Model (FFM) personality traits and a dimensional liability for psychosis. FFM traits according to the NEO-FFI and levels of subclinical psychotic symptoms according to the CAPE were assessed in 217 patients with psychotic disorders, 281 of their siblings and 176 healthy controls. Psychotic symptoms according to the PANSS were assessed in the patient group. Patients differed from siblings and controls on four of the five FFM traits, all but Openness. Siblings reported higher levels of Neuroticism than controls, but lower levels than patients. Particularly lower Agreeableness, and to a lesser degree, higher Neuroticism and lower Extraversion were associated with more severe symptoms in patients. Furthermore, higher Neuroticism and higher Openness were associated with higher levels of subclinical psychotic experiences in all three groups. Associations were strongest in patients. Our findings suggest that levels of Neuroticism increase with the level of familial risk for psychosis. Levels of Openness may reflect levels of impairment that distinguish clinical from subclinical symptomatology. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

There has been considerable recent interest in possible causal linkages between exposure to bullying victimization and later psychotic symptomatology. Prior research in this area has had several limitations which make it difficult to ascertain causality, and to determine the extent to which these effects extend beyond adolescence. Data were obtained from the Christchurch Health and Development Study, a 35-year study of a longitudinal birth cohort. This investigation used generalized estimating equation modelling to estimate the associations between bullying victimization (ages 13-16 years) and psychotic symptoms (ages 18-35 years), before and after controlling for possible confounding factors, including: gender; childhood socio-economic status; child intelligence quotient; exposure to sexual abuse in childhood; anxious/withdrawn behaviour and attention problems (ages 7-9 years); and adolescent psychotic symptoms and paranoid ideation (ages 15-16 years). There was a significant (p bullying victimization in adolescence and psychotic symptomatology in adulthood. Successive models controlling for covariation reduced this association to statistical non-significance. After controlling for covariates, those with the highest level of bullying victimization had rates of psychotic symptoms that were 1.21 (95% confidence interval 0.73-1.99) times higher than those who were not victimized. The association between bullying victimization in adolescence and psychotic symptomatology in adulthood could be largely explained by childhood behavioural problems, and exposure to sexual abuse in childhood. The results suggest that bullying victimization was unlikely to have been a cause of adult psychotic symptoms, but bullying victimization remained a risk marker for these symptoms.

Deficits in working memory (WM) and emotion processing are prominent impairments in psychotic disorders, and have been linked to reduced quality of life and real-world functioning. Translation of knowledge regarding the neural circuitry implementing these deficits into improved diagnosis and targeted treatments has been slow, possibly because of categorical definitions of disorders. Using the dimensional Research Domain Criteria (RDoC) framework, we investigated the clinical and practical utility of transdiagnostic behavioral and neural measures of emotion-related WM disruption across psychotic disorders. Behavioral and functional MRI data were recorded while 53 participants with psychotic disorders and 29 participants with no history of psychosis performed a modified n-back task with fear and neutral distractors. Hierarchical regression analyses showed that psychotic symptoms entered after diagnosis accounted for unique variance in fear versus neutral accuracy and activation in the ventrolateral, dorsolateral, and dorsomedial prefrontal cortex, but diagnostic group entered after psychotic symptoms did not. These results remained even after controlling for negative symptoms, disorganized symptoms, and dysphoria. Finally, worse accuracy and greater prefrontal activity were associated with poorer social functioning and unemployment across diagnostic groups. Present results support the transdiagnostic nature of behavioral and neuroimaging measures of emotion-related WM disruption as they relate to psychotic symptoms, irrespective of diagnosis. They also provide support for the practical utility of these markers in explaining real-world functioning. Overall, these results elucidate key aspects of the RDoC construct of WM maintenance by clarifying its transdiagnostic importance and clinical utility in psychotic disorders.

Full Text Available Abstract Background Psychotic major depression is a clinical subtype of major depressive disorder. A number of clinical studies have demonstrated the efficacy of the combination of an antidepressant (for example, a tricyclic antidepressant or selective serotonin reuptake inhibitor (SSRI and an atypical antipsychotic or electroconvulsive therapy (ECT in treating psychotic major depression. In several studies, monotherapy of SSRIs such as fluvoxamine has been shown to be effective in the treatment of psychotic major depression. Methods We report on a 36-year-old Japanese woman in whom fluvoxamine (a SSRI with sigma-1 receptor agonist and sertraline (a SSRI with sigma-1 receptor antagonist showed the opposite effects on psychotic symptoms in the treatment of psychotic major depression. Results Symptoms of depression and psychosis in the patient who was non-respondent to antipsychotic drugs improved after fluvoxamine monotherapy. At 3 years later, a switch to sertraline from fluvoxamine dramatically worsened the psychotic symptoms in the patient. Then, a switch back to fluvoxamine from sertraline improved these symptoms 1 week after fluvoxamine treatment. Conclusion Doctors should consider the monotherapy of sigma-1 receptor agonist fluvoxamine as an alternative approach to treating psychotic major depression.

Neuropathic pain, ie, pain arising directly from a lesion or disease affecting the somatosensory afferent pathway, manifests with various symptoms, the commonest being ongoing burning pain, electrical shock-like sensations, and dynamic mechanical allodynia. Reliable insights into the mechanisms underlying neuropathic pain symptoms come from diagnostic tests documenting and quantifying somatosensory afferent pathway damage in patients with painful neuropathies. Neurophysiological investigation and skin biopsy studies suggest that ongoing burning pain primarily reflects spontaneous activity in nociceptive-fiber pathways. Electrical shock-like sensations presumably arise from high-frequency ectopic bursts generated in demyelinated, nonnociceptive, Aβ fibers. Although the mechanisms underlying dynamic mechanical allodynia remain debatable, normally innocuous stimuli might cause pain by activating spared and sensitized nociceptive afferents. Extending the mechanistic approach to neuropathic pain symptoms might advance targeted therapy for the individual patient and improve testing for new drugs.

The use of cannabis has been linked to an increased risk for psychosis, irrespective of confounding factors such as age, gender, use of other drugs and reverse causality. Over the last few years a great deal of research has been done to broaden our understanding of the underlying mechanisms of this link. To update studies that have examined the link between cannabis use and psychosis and that have investigated the possible mechanisms underlying this link. This article discusses recent epidemiological and experimental research that sheds light on the nature of the link and the influence of interactions between genes and environment. The long-term effects of cannabis on the risk factors for psychosis and psychotic disorders are influenced to a large extent by genetic and environmental factors. Furthermore, patients with a psychotic disorder seem to be extremely vulnerable to the acute effects of cannabis. Studies show that cannabis use is an important risk factor for psychosis and psychotic disorders. So far, however, less research has been done into the effects of cannabis use on patients already suffering from a psychotic disorder.

While it is now recognized that psychotic experiences are associated with an increased risk of later mental disorders, we lack a detailed understanding of the reciprocal time-lagged relationships between first onsets of psychotic experiences and mental disorders. Using data from World Health Organization World Mental Health (WMH) Surveys, the authors assessed the bidirectional temporal associations between psychotic experiences and mental disorders. The WMH Surveys assessed lifetime prevalence and age at onset of psychotic experiences and 21 common DSM-IV mental disorders among 31,261 adult respondents from 18 countries. Discrete-time survival models were used to examine bivariate and multivariate associations between psychotic experiences and mental disorders. Temporally primary psychotic experiences were significantly associated with subsequent first onset of eight of the 21 mental disorders (major depressive disorder, bipolar disorder, generalized anxiety disorder, social phobia, posttraumatic stress disorder, adult separation anxiety disorder, bulimia nervosa, and alcohol abuse), with odds ratios ranging from 1.3 (95% CI=1.2-1.5) for major depressive disorder to 2.0 (95% CI=1.5-2.6) for bipolar disorder. In contrast, 18 of 21 primary mental disorders were significantly associated with subsequent first onset of psychotic experiences, with odds ratios ranging from 1.5 (95% CI=1.0-2.1) for childhood separation anxiety disorder to 2.8 (95% CI=1.0-7.8) for anorexia nervosa. While temporally primary psychotic experiences are associated with an elevated risk of several subsequent mental disorders, these data show that most mental disorders are associated with an elevated risk of subsequent psychotic experiences. Further investigation of the underlying factors accounting for these time-order relationships may shed light on the etiology of psychotic experiences.

Psychosis - an impaired contact with reality - is a hallmark of schizophrenia. Many psychotic symptoms are associated with disruptions in agency - the sense that 'I' cause my actions. A failure to predict sensory consequences of one's own actions may underlie agency disturbances. Such predictions rely on corollary discharge (CD) signals, 'copies' of movement commands sent to sensory regions prior to action execution. Here, we make a case that the oculomotor system is a promising model for understanding CD in psychosis, building on advances in our understanding of the behavioral and neurophysiological correlates of CD associated with eye movements. In this opinion article, we provide an overview of recent evidence for disturbed oculomotor CD in schizophrenia, potentially linking bizarre and disturbing psychotic experiences with basic physiological processes.

Different forms of artistic expression, such as literature and cinema, constitute an inexhaustible source for the study of mental illness. The use of psychodynamic models may contribute to a better understanding of the spectrum between personality disorders and the psychosis spectrum, thus enriching the phenomenological approach in the psychiatric clinical practice. To examine from psychodynamic standpoints the main character of the American film Black Swan, and the nature of her psychotic symptoms. Reviewing of sources and relevant theoretical currents. Analysis shows the usefulness of a psychodynamically- oriented dimensional model for understanding the so-called psychotic breaks as well as the applicability of psychoanalytic psychosis theories in general psychiatric practice, as they may provide a more flexible clinical approach, closer to the patient's subjective experience.

Full Text Available ABSTRACT: A lot of people live situations of mental sickness, from psychotic character, that can cause suffering both for the sick and his family. We believe that try this situation means to live with limitations and wearings in the familiar everyday, what makes difficult the living with the psychotic person. Considering these aspects, this research has the purpose of knowing the familiar perception about his living with a psychotic bearer person. It is about a qualitative, explorative and descriptive study, developed in a northwest city of Rio Grande do Sul state, called Ijuí. The people of the investigation are composed of five psychotic’s parents, which frequent the socioterapy group in Gloria district. The information collection happened trough open interviews, recorded and wrote out at all. The analysis of the obtained data followed MINAYO’s (2002 methodological proposition. By the contained information in the stud’s social actor’s declarations, emerged three thematic with a similar nucleus of thoughts. On first thematic, we discussed about the difficulties faced by the familiars in the living with the psychotic in the moment he has the acute symptoms. On the second thematic, we talked about the medical question as bring a therapeutic element that helps the mental sick to keep stable., becoming better the familiars life. The third thematic shows the family conception about mental sickness. With this research we concluded that the living with a mental sick person is taxing for the familiar and, sometimes, there are difficulties to understand the symptoms showed by the sick person. Besides that, the family considers the medication one of the most important possibilities of intervention in the psychotic’s therapy, what is reinforced by the health team that leads with these people.

With sufficient drug exposure, some individuals develop transient psychotic symptoms referred to as 'substance-induced psychosis' (SIP), which closely resemble the symptoms observed in schizophrenia spectrum disorders. The comparability in psychotic presentation between SIP and the schizophrenias suggests that similar underlying neural deficits may contribute to the emergence of psychosis across these disorders. Only a small number of studies have investigated structural alterations in SIP, and all have been limited to volumetric imaging methods, with none controlling for the effects of chronic drug exposure. To investigate white matter abnormalities associated with SIP, diffusion tensor imaging was employed in a group of individuals with cocaine-associated psychosis (CAP; n = 24) and a cocaine-dependent non-psychotic (CDN) group (n = 43). Tract-based spatial statistics was used to investigate group differences in white matter diffusion parameters. The CAP group showed significantly lower fractional anisotropy values than the CDN group (p psychosis. © 2016 Society for the Study of Addiction.

principles for first-episode psychosis are to maximise benefit and minimise side effects because the first experience of medication may influence a patient's future attitudes of therapy of all types. Effective strategies which may reduce long-term morbidity and improve recovery are currently available but their implementation is too often delayed. The time lag between the onset of symptoms and the start of treatment can be many months or years and this delay can have serious consequences. The critical period of the first 2-5 years after the first psychotic episode is a time of maximum vulnerability and of maximum opportunity. Consequently, actions should be undertaken to promote early recognition and assistance in psychotic disorders: understanding of the factors that may cause delay in treatment can help minimise this problem and lead to the initiation of appropriate treatment at the earliest opportunity. Training the general practitioners who have an important part to play in the early recognition is also of crucial importance.

Full Text Available BackgroundA diagnosis of psychotic disorder is traditionally considered incompatible with borderline personality disorder (BPD, even though patients sometimes fulfill the diagnostic criteria for both disorders. How often this happens is barely known, as is the influence of comorbid psychotic disorders on the outcome of BPD. Since studies on isolated auditory verbal hallucinations in patients with BPD indicate that these perceptual symptoms have severe consequences and are associated with suicidal behavior and hospitalization, patients with comorbid psychotic disorders are unlikely to fare better.ObjectiveTo examine the point prevalence of psychotic disorders in patients with BPD, their association with the outcome of BPD, and their predictive value for outcome.MethodsIn a cross-sectional design, 84 female outpatients diagnosed with BPD were interviewed with the aid of the MINI-International Neuropsychiatric Interview to establish the point prevalence of comorbid psychotic and other comorbid disorders. After termination of their treatment at a specialized outpatient clinic, the type of referral was considered to be a “good” outcome when they were referred to their general practitioner or to basic psychiatric care for noncomplex patients, and a “poor” outcome when referred to a specialized psychiatric department or to a psychiatric district team for patients with severe psychiatric disorders.ResultsPsychotic disorders were present in 38% of the patients with BPD. With a prevalence of 20%, psychotic disorder not otherwise specified (NOS was the most common subtype; the least common types were schizophrenia (2%, substance-induced psychotic disorder (2%, and brief psychotic disorder (1%. Among six types of comorbid disorders, only psychotic disorders were associated with a poor outcome; they were also predictors for a poor outcome, along with comorbid mood disorders, eating disorders, and somatoform disorders, as well as the severity of BPD

A substantial amount of refugees (10-30%) suffer from Post-Traumatic Stress Disorder (PTSD). In Denmark there are different facilities specialised in psychiatric treatment of trauma-affected refugees. A previously published case report from such a facility in Denmark shows that some patients suffer from secondary psychotic symptoms alongside their PTSD. The aim of this study was to illustrate the characteristics and estimate the prevalence of psychotic features in a clinical population of trauma-affected refugees with PTSD. Psychiatric records from 220 consecutive patients at Competence Centre for Transcultural Psychiatry (CTP) were examined, and all the PTSD patients were divided into two groups; one group with secondary psychotic features (PTSD-SP group) and one without (PTSD group). A categorisation and description of the secondary psychotic features was undertaken. One hundred eighty-one patients were diagnosed with PTSD among which psychotic symptoms were identified in 74 (40.9, 95% CI 33.7-48.1%). The majority of symptoms identified were auditory hallucinations (66.2%) and persecutory delusions (50.0%). There were significantly more patients diagnosed with enduring personality change after catastrophic experience in the PTSD-SP group than in the PTSD group (P = 0.009). Furthermore the PTSD-SP group included significantly more patients exposed to torture (P = 0.001) and imprisonment (P = 0.005). This study provides an estimation of PTSD-SP prevalence in a clinical refugee population with PTSD. The study points to the difficulties distinguishing psychotic features from flashbacks and the authors call for attention to psychotic features in PTSD patients in order to improve documentation and understanding of the disorder.
Full Text Available ObjectiveSun exposure is considered the single most important source of vitamin D. Vitamin D deficiency has been suggested to play a role in the etiology of psychotic disorders. The aim of the present study was to evaluate the association between sun exposure and psychotic experiences (PEs in a general population sample of Swedish women.MethodsThe study population included participants from The Swedish Women’s Lifestyle and Health cohort study. The 20-item community assessment of psychic experiences (CAPEs was administered between ages 30 and 50 to establish PEs. Sun exposure as measured by (1 sunbathing holidays and (2 history of sunburn was measured between ages 10 and 39. The association between sun exposure and PEs was evaluated by quantile regression models.Results34,297 women were included in the analysis. Women who reported no sunbathing holidays and 2 or more weeks of sunbathing holidays scored higher on the CAPE scale than women exposed to 1 week of sunbathing holidays across the entire distribution, when adjusting for age and education. Similarly, compared with women who reported a history of one sunburn, the women with none or two or more sunburns showed higher scores on the CAPE scale.ConclusionThe results of the present study suggest that, in a population-based cohort of middle aged women, both low and high sun exposure is associated with increased level of positive PEs.
Full Text Available Abstract Background There is emerging evidence that antidepressants may be effective in preventing patients with non-specific and psychotic-like prodromal symptoms, defined as patients at ultra-high risk (UHR of psychotic disorder, from transitioning to psychosis. However, the mechanism of such an effect is still unknown. Methods We report the case of a 19-year-old Japanese man determined to be at UHR of psychotic disorder in whom fluvoxamine (one of the antidepressants with sigma-1 receptor agonism showed preventive effects on psychotic-like prodromal symptoms. Results Our patient's depressive symptoms were reduced and maintained below remission as a result of treatment with 100 mg/day of fluvoxamine. In addition, it is likely that an additional dose of fluvoxamine (50 mg/day improved his psychotic-like prodromal symptoms directly, independent of its antidepressive effects. Conclusion Fluvoxamine, a sigma-1 receptor agonist, may be effective in preventing patients at UHR of psychotic disorder from onset of psychosis via its neuroprotective/neurotropic actions, independent of its antidepressive effects.

Individuals who report psychotic-like experiences are at increased risk of future clinical psychotic disorder. They constitute a unique "high-risk" group for studying the developmental trajectory to schizophrenia and related illnesses. Previous research has used screening instruments to identify this high-risk group, but the validity of these instruments has not yet been established. We administered a screening questionnaire with 7 items designed to assess psychotic-like experiences to 334 adolescents aged 11-13 years. Detailed clinical interviews were subsequently carried out with a sample of these adolescents. We calculated sensitivity and specificity and positive predictive value (PPV) and negative predictive value (NPV) for each screening question for the specific symptom it enquired about and also in relation to any psychotic-like experience. The predictive power varied substantially between items, with the question on auditory hallucinations ("Have you ever heard voices or sounds that no one else can hear?") providing the best predictive power. For interview-verified auditory hallucinations specifically, this question had a PPV of 71.4% and an NPV of 90.4%. When assessed for its predictive power for any psychotic-like experience (including, but not limited to, auditory hallucinations), it provided a PPV of 100% and an NPV of 88.4%. Two further questions-relating to visual hallucinations and paranoid thoughts-also demonstrated good predictive power for psychotic-like experiences. Our results suggest that it may be possible to screen the general adolescent population for psychotic-like experiences with a high degree of accuracy using a short self-report questionnaire.

The ADHD-obesity link has been suggested to result from a shared underlying basis of suboptimal dopamine (DA); however, this theory conflicts evidence that an amplified DA signal increases the risk for overeating and weight gain. A model was tested in which ADHD symptoms, predicted by hypodopaminergic functioning in the prefrontal cortex, in combination with an enhanced appetitive drive, predict hedonic eating and, in turn, higher body mass index (BMI). DRD2 and DRD4 markers were genotyped. The model was tested using structural equation modeling in a nonclinical sample (N = 421 adults). The model was a good fit to the data. Controlling for education, all parameter estimates were significant, except for the DRD4-ADHD symptom pathway. The significant indirect effect indicates that overeating mediated the ADHD symptoms-BMI association. Results support the hypothesis that overeating and elevated DA in the ventral striatum-representative of a greater reward response-contribute to the ADHD symptom-obesity relationship. © The Author(s) 2016.

After prolonged psychostimulant abuse, transient psychotic symptoms referred to as "substance-induced psychosis" (SIP) can develop - closely resembling symptoms observed in schizophrenia spectrum disorders. The comparability in psychotic presentation between SIP and schizophrenias suggests that similar underlying neural deficits may contribute to the expression of psychosis across these disorders. To date, neuroanatomical characterization of grey matter structural alterations in SIP has been limited to methamphetamine associated psychosis, with no studies controlling for potential neurotoxic effects of the psychostimulant that precipitates psychosis. To investigate grey matter subcortical alterations in SIP, a voxel-based analysis of magnetic resonance images (MRI) was performed between a group of 74 cocaine dependent nonpsychotic individuals and a group of 29 individuals with cocaine-associated psychosis. The cocaine-associated psychosis group had significantly smaller volumes of the thalamus and left hippocampus, controlling for age, total brain volume, current methamphetamine dependence, and current marijuana dependence. No differences were present in bilateral caudate structures. The findings of reduced thalamic and hippocampal volumes agree with previous reports in the schizophrenia literature, suggesting alterations of these structures are not specific to schizophrenia, but may be common to multiple forms of psychosis.

Traumatic life events have been robustly associated with various psychosis outcomes, including increased risk of psychotic disorders, the prodrome of psychosis, and dimensional measures of psychotic symptoms, such as attenuated positive psychotic symptoms. However, trauma exposure has been linked to various mental disorders; therefore, the specificity of trauma exposure to psychosis remains unclear. This review focuses on two understudied areas of the trauma and psychosis literature: 1) the specificity between trauma and psychosis in relation to other disorders that often result post-trauma, and 2) proposed mechanisms that uniquely link trauma to psychosis. We begin by discussing the underlying connection between trauma exposure and the entire psychosis spectrum with a focus on the influence of trauma type and specific psychotic symptoms. We then consider how the principles of multifinality and equifinality can be useful in elucidating the trauma-psychosis relationship versus the trauma-other disorder relationship. Next, we discuss several cognitive and neurobiological mechanisms that might uniquely account for the association between trauma and psychosis, as well as the role of gender. Lastly, we review important methodological issues that complicate the research on trauma and psychosis, ending with clinical implications for the field. PMID:27632064

Various approaches have been made over the years to classify psychotic patients according to inadequate treatment response, using terms such as treatment resistant or treatment refractory. Existing classifications have been criticized for overestimating positive symptoms; underestimating residual symptoms, negative symptoms, and side effects; or being to open for individual interpretation. The aim of this study was to present and evaluate a new method of classification according to treatment response and, thus, to identify patients in functional remission. A naturalistic, cross-sectional study was performed using patient interviews and information from patient files. The new classification method CANSEPT, which combines the Camberwell Assessment of Need rating scale, the Udvalg for Kliniske Undersøgelser side effect rating scale (SE), and the patient's previous treatment history (PT), was used to group the patients according to treatment response. CANSEPT was evaluated by comparison of expected and observed results. In the patient population (n = 123), the patients in functional remission, as defined by CANSEPT, had higher quality of life, fewer hospitalizations, fewer psychotic symptoms, and higher rate of workers than those with the worst treatment outcome. In the evaluation, CANSEPT showed validity in discriminating the patients of interest and was well tolerated by the patients. CANSEPT could secure inclusion of correct patients in the clinic or in research.
The concept of cycloid psychosis or cycloid psychotic disorder has been used in the European psychiatric literature for almost half a century. However, it has now for the first time been comprised into the 10th revision of the World Health Organization's International Classification of Diseases (ICD-10) that is currently in the phase of field trials. In this article evidence is presented that supports the independence of cycloid psychotic disorder from other major psychotic disorders. In particular, evidence is presented in favour of the clinical and predictive validity of the cycloid psychosis construct. Issues related to treatment are discussed and suggestions for future research are given.

People suffering from psychiatric disorders abuse alcohol or illicit substances twice as frequently as the general population. This problem is even more frequent in the early phase of psychotic disorders where prevalence of substance abuse ranges, according to various studies, from 35 to 65% during first psychotic episode. Cannabis is currently the most frequently used substance, and although its impact is often minimised, many data suggest it constitutes a risk for psychosis at three levels: (a) possible toxic psychosis in healthy individuals, (b) relapse of positive symptoms in schizophrenia and (c) raises the risk of schizophrenia when used early during adolescence. Despite a persistent controversy regarding some of these findings, they have constituted a sufficient body of evidence to support the development of specific interventions for psychotic patients. Various authors have described the fundamental elements of such dual diagnosis treatments, and some intervention programs have recently been developed. However, their relative complexity and the long duration of such interventions are often not well adapted to patients with limited motivation and low level of insight. Moreover, many obstacles arise that complicate their application to early psychotic disorders: minimisation of deleterious effect of cannabis by young people, distrust linked to psychotic symptoms, cognitive disturbances, stigmatisation of psychiatry, and use of cannabis as a means to socialise with peers. It is therefore important to adapt interventions to the specific needs of such patients and particularly to adopt a realistic attitude, aiming at increasing motivation to change habits and minimising associated risks rather than total abstinence. Our objective is to develop a pragmatic, non-judgemental approach, based on motivational interviewing techniques that is adapted to early psychosis with comorbid cannabis abuse, aimed at reducing the risks associated with abuse.

Post-psychotic depression (PPD) is defined as the development of depression during the phase of remission of schizophrenia. Two groups of DSM-III-R schizophrenics, one with PPD and the other without PPD (30 subjects in each group) were compared. Significantly more patients in PPD group belonged to nuclear families, had longer duration of psychotic phase of the illness, were hospitalised more frequently and had more sadness and anxiety-somatisation during florid illness phase. The PPD group also had more past history of depression. Although PPD patients had better premorbid personal-social adjustment in comparison with non-PPD group, they perceived themselves to be lacking in social support and had experienced more stressful life events. For patients in the PPD group, stepwise multiple regression analysis revealed age of onset, sadness during florid psychotic state, premorbid adjustment, social support and life events as significant determinants of severity of depression in the post-psychotic phase.

Victims of bullying are at risk for psychotic experiences in early adolescence. It is unclear if this elevated risk extends into late adolescence. The aim of this study was to test whether bullying perpetration and victimization in elementary school predict psychotic experiences in late adolescence. The current study is based on the Avon Longitudinal Study of Parents and Children (ALSPAC), a prospective community-based study. A total of 4720 subjects with bullying perpetration and victimization were repeatedly assessed between the ages of 8 and 11 years by child and mother reports. Suspected or definite psychotic experiences were assessed with the Psychosis-Like Symptoms semi-structured interview at age 18 years. Controlling for child's gender, intelligence quotient at age 8 years, childhood behavioural and emotional problems, and also depression symptoms and psychotic experiences in early adolescence, victims [child report at 10 years: odds ratio (OR) 2.4, 95% confidence interval (CI) 1.6-3.4; mother report: OR 1.6, 95% CI 1.1-2.3], bully/victims (child report at 10 years: OR 3.1, 95% CI 1.7-5.8; mother: OR 2.9, 95% CI 1.7-5.0) and bullies (child report at 10 years: OR 4.9, 95% CI 1.3-17.7; mother: OR 1.2, 95% CI 0.46-3.1, n.s.) had a higher prevalence of psychotic experiences at age 18 years. Path analysis revealed that the association between peer victimization in childhood and psychotic experiences at age 18 years was only partially mediated by psychotic or depression symptoms in early adolescence. Involvement in bullying, whether as victim, bully/victim or bully, may increase the risk of developing psychotic experiences in adolescence. Health professionals should ask routinely during consultations with children about their bullying of and by peers.

Full Text Available Based on a case of an acute and transient psychotic disorder with full recovery between recurrences, the authors remind the concept of cycloid psychoses. This diagnosis has been neglected in modern psychiatry and in the current nosological systems. However, the cycloid psychoses concept may offer an alternative diagnosis for some psychotic disorders in spite of the need of more studies to improve the understanding of its etiology and treatment.

Most theories of psychotic-like experiences posit the involvement of social-cognitive mechanisms. The current research examined the relations between psychotic-like experiences and two social-cognitive mechanisms, high aberrant salience and low self-concept clarity. In particular, we examined whether aberrant salience, or the incorrect assignment of importance to neutral stimuli, and low self-concept clarity interacted to predict psychotic-like experiences. The current research included three large samples (n = 667, 724, 744) of participants and over-sampled for increased schizotypal personality traits. In all three studies, an interaction between aberrant salience and self-concept clarity was found such that participants with high aberrant salience and low self-concept clarity had the highest levels of psychotic-like experiences. In addition, aberrant salience and self-concept clarity interacted to predict a supplemental measure of delusions in Study 2. In Study 3, in contrast to low self-concept clarity, neuroticism did not interact with aberrant salience to predict psychotic-like experiences, suggesting that the relation between low self-concept clarity and psychosis may not be due to neuroticism. Additionally, aberrant salience and self-concept clarity did not interact to predict to other schizotypal personality disorder criteria, social anhedonia or trait paranoia, which suggests the interaction is specific to psychotic-like experiences. Overall, our results are consistent with several social-cognitive models of psychosis suggesting that aberrant salience and self-concept clarity might be important mechanisms in the occurrence of psychotic-like symptoms.

Recent research conducted in high-income countries suggests psychotic experiences are common in the general population, but evidence from low- and middle-income countries (LMIC) remains limited. Sri Lanka is a LMIC affected by three decades of civil conflict and, in 2004, a devastating tsunami. This study aimed to investigate the prevalence of psychotic experiences in a general population sample in Sri Lanka and associations with conflict- and tsunami-related trauma. This is a first National Mental Health Survey conducted in Sri Lanka. A cross-sectional, multi-stage, cluster sampling design was used to estimate the prevalence of psychotic symptoms. Data on socio-demographic characteristics, conflict- and tsunami-related trauma, and psychotic experiences were collected using culturally validated measures in a sample of 5927 participants. The weighted prevalence of psychotic symptoms was 9.7%. Exposure to one or more conflict-related events (adj. OR 1.79, 95% CI 1.40-2.31, pSri Lankan population.

To prospectively assess the relationship between cannabis use and psychotic experiences over time. In a longitudinal design, young adults aged 18-27years (N=705) gave online information on cannabis use and completed the Community Assessment of Psychic Experiences (CAPE). These measures were repeated after an interval ranging from six months to five years. A decrease in cannabis use was associated with a decrease in total psychotic experiences (β=-0.096, p=0.01) after adjustment for a range of potential confounders. An increase in cannabis use was associated with increased positive symptoms at follow-up (β=0.07, p=0.02), but was not significantly associated with increases in Negative and Depression symptom scores, nor with the total number of psychotic experiences. In the first study to the association of change in cannabis use and psychotic experiences over time in the general population, we found an association between changes in cannabis use and changes in the frequency of psychotic experiences. While this does not prove a causal relationship between cannabis use and psychosis, our findings are consistent with studies suggesting that cessation of cannabis use may be beneficial in terms of reducing psychotic experiences.

Fahr's syndrome is a rare disorder characterized by abnormal deposits of calcium in areas of the brain that control movement, including the basal ganglia and the cerebral cortex associated with many neurological and psychiatric abnormalities such as a rigid hypokinetic syndrome, mood disorders and cognitive impairment. Fahr's syndrome is secondary to some disorders, such as hypoparathyroidism. We report the case of a 56 year-old man, with a history of cataract, who was admitted to our psychiatric hospital for the first time in his life because of psychotic symptoms associated with irritability and aggressiveness. Since the age of 38 the patient had become nervous, 10 years later he developed tonic-clonic seizures. Two months ago, he began expressing delusions of persecution against his wife and sons and making fugues. According to his family during this period, he was agitated, aggressive, and suffered from insomnia and anorexia. The general and psychiatric examination showed an upright and bronzed patient with neglected hygiene. He was indifferent to his environment and expressed poor mimics and gestures. He was anxious, suspicious and not very talkative. He was conscious but his attention was slightly decreased. Moreover, he was not aware of his problems. The neurological examination showed extrapyramidal syndrome with postural tremor and cerebellar ataxia. A cranial computed tomography brain scan found bilateral, symmetric basal ganglia calcifications, in favour of Fahr's syndrome. Phosphocalcic investigations revealed low concentration of serum calcium at 1.01mmol/L (normal 2.15 to 2.57mmol/L) and hyperphosphoremia at 2.69mmol/L (normal 0.81 to 1.55mmol/L). He also had low concentrations of 25-OH vitamin as well as decreased urinary levels of phosphate and calcium. The blood level of parathyroid hormone was 0ng/L. The diagnosis of Fahr's syndrome, revealing a hypoparathyroidism was posed. He was supplemented with calcium and alpha cholecalciferol and treated

Evidence suggests that social networks of patients with psychotic disorders influence symptoms, quality of life and treatment outcomes. It is therefore important to assess social networks for which appropriate and preferably established instruments should be used. To identify instruments assessing social networks in studies of patients with psychotic disorders and explore their properties. A systematic search of electronic databases was conducted to identify studies that used a measure of social networks in patients with psychotic disorders. Eight instruments were identified, all of which had been developed before 1991. They have been used in 65 studies (total N of patients = 8,522). They assess one or more aspects of social networks such as their size, structure, dimensionality and quality. Most instruments have various shortcomings, including questionable inter-rater and test-retest reliability. The assessment of social networks in patients with psychotic disorders is characterized by a variety of approaches which may reflect the complexity of the construct. Further research on social networks in patients with psychotic disorders would benefit from advanced and more precise instruments using comparable definitions of and timescales for social networks across studies.

Despite significant research efforts aimed at understanding the neurobiological underpinnings of mood (depression, bipolar disorder) and psychotic disorders, the diagnosis and evaluation of treatment of these disorders are still based solely on relatively subjective assessment of symptoms as well as psychometric evaluations. Therefore, biological markers aimed at improving the current classification of psychotic and mood-related disorders, and that will enable patients to be stratified on a biological basis into more homogeneous clinically distinct subgroups, are urgently needed. The attainment of this goal can be facilitated by identifying biomarkers that accurately reflect pathophysiologic processes in these disorders. This review postulates that the field of psychotic and mood disorder research has advanced sufficiently to develop biochemical hypotheses of the etiopathology of the particular illness and to target the same for more effective disease modifying therapy. This implies that a “one-size fits all” paradigm in the treatment of psychotic and mood disorders is not a viable approach, but that a customized regime based on individual biological abnormalities would pave the way forward to more effective treatment. In reviewing the clinical and preclinical literature, this paper discusses the most highly regarded pathophysiologic processes in mood and psychotic disorders, thereby providing a scaffold for the selection of suitable biomarkers for future studies in this field, to develope biomarker panels, as well as to improve diagnosis and to customize treatment regimens for better therapeutic outcomes.

Recent studies have successfully investigated the validity of the DSM-5 Alternative Model for Personality Disorders. In a final sample of 174 psychiatric patients, the present study examined the relationship between the Personality Inventory for the DSM-5 (PID-5) and syndromal psychosis. Results showed that patients diagnosed with versus without a psychotic disorder significantly differed on all PID-5 domains except Antagonism. Discriminant function analysis indicated that lower Detachment, lower Negative Affect, lower Disinhibition, and higher Psychoticism best discriminated patients with a psychotic disorder from patients with other psychiatric conditions. Subsequent stepwise discriminant analysis on all facet scales of the contributing PID-5 domains revealed that higher Unusual Beliefs, lower Depressivity, and lower Distractibility contributed the most to this differentiation. PID-5 Psychoticism scores showed moderate correlations with current psychotic symptoms and were not influenced by dose of antipsychotic medication. Our results support the ability of the PID-5 to discriminate between patients with and without psychotic disorder.

Many patients with a non-affective psychotic disorder suffer from impairments in social functioning and social cognition. To target these impairments, mentalization-based treatment for psychotic disorder, a psychodynamic treatment rooted in attachment theory, has been developed. It is expected to improve social cognition, and thereby to improve social functioning. The treatment is further expected to increase quality of life and the awareness of having a mental disorder, and to reduce substance abuse, social stress reactivity, positive symptoms, negative, anxious and depressive symptoms. The study is a rater-blinded randomized controlled trial. Patients are offered 18 months of therapy and are randomly allocated to mentalization-based treatment for psychotic disorders or treatment as usual. Patients are recruited from outpatient departments of the Rivierduinen mental health institute, the Netherlands, and are aged 18 to 55 years and have been diagnosed with a non-affective psychotic disorder. Social functioning, the primary outcome variable, is measured with the social functioning scale. The administration of all tests and questionnaires takes approximately 22 hours. Mentalization-based treatment for psychotic disorders adds a total of 60 hours of group therapy and 15 hours of individual therapy to treatment as usual. No known health risks are involved in the study, though it is known that group dynamics can have adverse effects on a psychiatric disorder. If Mentalization-based treatment for psychotic disorders proves to be effective, it could be a useful addition to treatment. Dutch Trial Register. NTR4747 . Trial registration date 08-19-2014.

Mental disorders (especially depression and dementia) are highly prevalent among multiple sclerosis (MS) patients. Schizophrenic-type psychosis has been reported only rarely most often in advanced cases and its possible pathophysiological and even causal relation to the demyelinating disease is disputed. We describe a woman with MS who experienced 2 episodes of acute psychosis after having had only one prior episode of focal neurological dysfunction. The coincidence of psychiatric symptoms and the appearance of new white matter lesions in both hemispheres was confirmed by CT and MRI during the second episode. We suggest that in this patient the psychotic symptoms do not depend on the strategic anatomical location of plates, but rather on the effect of nonspecific lesions in a patient previously predisposed to psychiatric disorder.

Background: The homicide of strangers by people with psychosis, referred to here as “stranger homicides,” are rare and tragic events that generate adverse publicity for mental health services and have resulted in significant changes in mental health policy and law. Aim: To estimate the incidence of stranger homicides, using data from previously published studies, and to compare the characteristics of psychotic offenders who killed strangers with the characteristics of those who killed a close relative. Method: Meta-analysis of the population-based studies of homicide by persons suffering from a psychosis in which the number of subjects who killed strangers was also reported. Characteristics of stranger homicide and family homicide offenders were examined in a multicenter case–control study of homicide during psychotic illness in four high-income countries. Results: A pooled estimate of 1 stranger homicide per 14.3 million people per year (95% confidence interval, 1 in 18.9 million to 1 in 11.5 million people per year) was calculated by meta-analysis of 7 studies. The characteristics of the 42 stranger homicide offenders from New South Wales [NSW], Quebec and Eastern Ontario, Finland, and the Netherlands were identified. Twenty seven (64%) of these had never previously received treatment with antipsychotic medication. The stranger homicide offenders were more likely to be homeless, have exhibited antisocial conduct, and had fewer negative symptoms than those who killed family members. The victims of stranger homicide were mostly adult males and the homicides rarely occurred in the victim’s home or workplace. Conclusions: Stranger homicide in psychosis is extremely rare and is even rarer for a patient who has received treatment with antipsychotic medication. A lack of distinguishing characteristics of stranger homicide offenders and an extremely low base rate of stranger-homicide suggests that risk assessment of patients known to have a psychotic illness will
Full Text Available Shared psychotic disorder or folie à deux is a rare and relatively unknown syndrome. Large case series are needed to find out and clarify the etiological factors and the phenomenology of shared psychotic disorder by comparing the cases from different society and cultures. In this study, we reviewed all reported cases of shared psychotic disorder that had been published or presented in Turkey since 1962. To reach this aim, we have searched Pubmed/Medline, ScienceDirect, Google Scholar, Ulakbim Turkish Medical Index, Turkish Psychiatric Index databases for published records originating from Turkey. We have also manually searched poster abstract books of congresses held in Turkey between 1962 and 2009. All cases eligible for inclusion into this study have been evaluated one by one and grouped as primary or secondary cases. The features of these cases were investigated for a number of variables including age, sex, educational level, occupation, the presence of shared delusion and hallucinations, diagnosis, management, onset of illness, family history, IQ, social isolation, the nature of the relationship and classification system used for diagnosis. The results have showed that the syndrome is more frequently observed among women, within same family members and between sisters. Social isolation was the most common risk factor in these patients and most patients shared hallucinations with their partners along with their delusions. Several secondary cases required antipsychotic drugs for the treatment of their symptoms. Though these features were inline with literature findings, the present findings from Turkish population were different from previous studies with regards to the presence of olfactory hallucinations, absence of grandiose delusions and the number of affected family members. The results mostly supported the challenges and discussions in western countries. To understand this most pathological form of interpersonal relationships

BACKGROUND: Knowledge on the significance of childhood psychotic symptoms and experiences (PE) is still limited. This study aimed to investigate the prevalence and clinical significance of PE in preadolescent children from the general population by use of in-depth psychopathological interviews...... and comprehensive diagnostic assessments. METHODS: We investigated 1,632 children from the general population-based Copenhagen Child Cohort 2000. PE were measured by semistructured interviews using the K-SADS-PL-items on psychotic and affective symptoms, each symptom scored as not present versus likely...... were examined by multivariable binomial regression analyses, adjusting for gender and onset of puberty. RESULTS: The weighted life time prevalence of PE at age 11-12 years was 10.9% (CI 9.1-12.7). The majority of children with PE (n = 172) either had a diagnosable DSM-IV-mental disorder (31.4%) or self...

Objectives To examine the association between clozapine treatment and frequency of cannabis use in adolescents with co-occurring psychotic and cannabis use disorder in a retrospective cohort chart review. Method We conducted a retrospective cohort chart review of patients diagnosed with a psychotic disorder and concurrent cannabis use disorder admitted to a tertiary care youth inpatient unit from 2010–2012. Longitudinal exposure and outcome data was coded month-by-month. Frequency of cannabis use was measured using a 7-point ordinal scale. Severity of psychosis was measured on a 3-point ordinal scale. Mixed effects regression modeling was used to describe the relationship between exposure and outcome variables. Results Thirteen patients had exposure to clozapine and fourteen had no exposure to clozapine. Cannabis use decreased in patients treated with clozapine, compared to patients treated with other antipsychotics (OR 2.8; 95% CI 0.97–7.9). Compared to no medication, clozapine exposure was associated with significantly less cannabis use (OR 7.1; 95% CI 2.3–22.3). Relative to treatment with other antipsychotics, clozapine exposure was significantly associated with lower severity of psychotic symptoms (OR 3.7; 95% CI 1.2–11.8). Conclusions Clozapine may lead to decreased cannabis use and psychotic symptoms in adolescents with concurrent psychosis and substance use. Clinical trials are warranted. PMID:28331504

It has been argued that attachment theory could enhance our knowledge and understanding of psychotic phenomenology. We systematically reviewed and critically appraised research investigating attachment and psychotic phenomenology in clinical and non-clinical samples. We searched databases Pub Med, PsycINFO, Medline and Web of Science using the keywords. Attachment, Adult Attachment, Psychosis, Schizotypy and Schizophrenia and identified 29 studies assessing adult attachment in combination with psychotic phenomenology. The findings indicated that both insecure anxious and insecure avoidant attachment are associated with psychotic phenomenology. Insecurely attached individuals are more vulnerable to developing maladaptive coping strategies in recovering from psychosis. The importance of attachment experiences for processing social information, mentalization skills and developing social relationships, including therapeutic relationships, in samples with psychosis is also highlighted. Attachment style is a clinically relevant construct in relation to development, course and treatment of psychosis. Understanding the role of attachment in symptoms may help to gain insight into the development or persistence of symptoms. Associations between attachment and recovery style suggest that it may be helpful to improve attachment security in a context of therapeutic relationships or other social relationships before encouraging people to explore their experiences of psychosis. Associations between insecure attachment and impaired mentalization skills may help in understanding interpersonal difficulties and this knowledge can be used to improve recovery. © 2013 The British Psychological Society.

Dysconnectivity in schizophrenia can be understood in terms of dysfunctional integration of a distributed network of brain regions. Here we propose a new methodology to analyze complex networks based on semi-metric behavior, whereby higher levels of semi-metricity may represent a higher level of redundancy and dispersed communication. It was hypothesized that individuals with (increased risk for) psychotic disorder would have more semi-metric paths compared to controls and that this would be associated with symptoms. Resting-state functional MRI scans were obtained from 73 patients with psychotic disorder, 83 unaffected siblings and 72 controls. Semi-metric percentages (SMP) at the whole brain, hemispheric and lobar level were the dependent variables in a multilevel random regression analysis to investigate group differences. SMP was further examined in relation to symptomatology (i.e., psychotic/cognitive symptoms). At the whole brain and hemispheric level, patients had a significantly higher SMP compared to siblings and controls, with no difference between the latter. In the combined sibling and control group, individuals with high schizotypy had intermediate SMP values in the left hemisphere with respect to patients and individuals with low schizotypy. Exploratory analyses in patients revealed higher SMP in 12 out of 42 lobar divisions compared to controls, of which some were associated with worse PANSS symptomatology (i.e., positive symptoms, excitement and emotional distress) and worse cognitive performance on attention and emotion processing tasks. In the combined group of patients and controls, working memory, attention and social cognition were associated with higher SMP. The results are suggestive of more dispersed network communication in patients with psychotic disorder, with some evidence for trait-based network alterations in high-schizotypy individuals. Dispersed communication may contribute to the clinical phenotype in psychotic disorder. In addition

Full Text Available BACKGROUND: S100B is a potential marker of neurological and psychiatric illness. In schizophrenia, increased S100B levels, as well as associations with acute positive and persisting negative symptoms, have been reported. It remains unclear whether S100B elevation, which possibly reflects glial dysfunction, is the consequence of disease or compensatory processes, or whether it is an indicator of familial risk. METHODS: Serum samples were acquired from two large independent family samples (n = 348 and n = 254 in the Netherlands comprising patients with psychotic disorder (n = 140 and n = 82, non-psychotic siblings of patients with psychotic disorder (n = 125 and n = 94 and controls (n = 83 and n = 78. S100B was analyzed with a Liaison automated chemiluminescence system. Associations between familial risk of psychotic disorder and S100B were examined. RESULTS: Results showed that S100B levels in patients (P and siblings (S were not significantly different from controls (C (dataset 1: P vs. C: B = 0.004, 95% CI -0.005 to 0.013, p = 0.351; S vs. C: B = 0.000, 95% CI -0.009 to 0.008, p = 0.926; and dataset 2: P vs. C: B = 0.008, 95% CI -0.011 to 0.028, p = 0.410; S vs. C: B = 0.002, 95% CI -0.016 to 0.021, p = 0.797. In patients, negative symptoms were positively associated with S100B (B = 0.001, 95% CI 0.000 to 0.002, p = 0.005 in one of the datasets, however with failure of replication in the other. There was no significant association between S100B and positive symptoms or present use or type of antipsychotic medication. CONCLUSIONS: S100B is neither an intermediate phenotype, nor a trait marker for psychotic illness.

The link between cannabis use and psychosis comprises three distinct relationships: acute psychosis associated with cannabis intoxication, acute psychosis that lasts beyond the period of acute intoxication, and persistent psychosis not time-locked to exposure. Experimental studies reveal that cannabis, tetrahydrocannabinol (THC) and synthetic cannabinoids reliably produce transient positive, negative, and cognitive symptoms in healthy volunteers. Case-studies indicate that cannabinoids can induce acute psychosis which lasts beyond the period of acute intoxication but resolves within a month. Exposure to cannabis in adolescence is associated with a risk for later psychotic disorder in adulthood; this association is consistent, temporally related, shows a dose-response, and is biologically plausible. However, cannabis is neither necessary nor sufficient to cause a persistent psychotic disorder. More likely it is a component cause that interacts with other factors to result in psychosis. The link between cannabis and psychosis is moderated by age at onset of cannabis use, childhood abuse and genetic vulnerability. While more research is needed to better characterize the relationship between cannabinoid use and the onset and persistence of psychosis, clinicians should be mindful of the potential risk of psychosis especially in vulnerable populations, including adolescents and those with a psychosis diathesis.

Work with dreams in the group analysis represents an important part of the analytical work, with insight into unconscious experiences of the individual dreamer, and his transferrential relations with the therapist, other members of the group, and with the group as a whole. The way dreams are addressed varies from one therapist to another, and in line with that, members of the group have varying frequency of dreams. In groups of psychotic patients dreams are generally rarely discussed and interpreted by the group, with analysis mainly resting on the manifested content. This paper describes a long-term group of psychotic patients which, after sharing the dreams of several members and daydreams of one female patient, their interpretation and reception in the group achieved better cohesion and improved communication and interaction, i.e. created a group matrix. Furthermore, through the content of dreams in the group, traumatic war experiences of several of the group members were opened and discussed, which brought with it recollections of the traumatic life situations of other group members. In expressing a daydream, a female member of the group revealed the background for her behaviour which was earlier interpreted as a negative symptom of the illness.

Full Text Available Introduction: History taking and physical examination help clinicians identify the patient’s problem and effectively treat it. This study aimed to evaluate the descriptors of dyspnea in patients presenting to emergency department (ED with asthma, congestive heart failure (CHF, and chronic obstructive pulmonary disease (COPD. Method: This cross-sectional study was conducted on all patients presenting to ED with chief complaint of dyspnea, during 2 years. The patients were asked to describe their dyspnea by choosing three items from the valid and reliable questionnaire or articulating their sensation. The relationship between dyspnea descriptors and underlying cause of symptom was evaluated using SPSS version 16. Results: 312 patients with the mean age of 60.96±17.01 years were evaluated (53.2% male. Most of the patients were > 65 years old (48.7% and had basic level of education (76.9%. "My breath doesn’t go out all the way" with 83.1%, “My chest feels tight " with 45.8%, and "I feel that my airway is obstructed" with 40.7%, were the most frequent dyspnea descriptors in asthma patients. "My breathing requires work" with 46.3%, "I feel that I am suffocating" with 31.5%, and "My breath doesn’t go out all the way" with 29.6%, were the most frequent dyspnea descriptors in COPD patients. "My breathing is heavy" with 74.4%, "A hunger for more air” with 24.4%, and "I cannot get enough air" with 23.2%, were the most frequent dyspnea descriptors in CHF patients. Except for “My breath does not go in all the way”, there was significant correlation between studied dyspnea descriptors and underlying disease (p = 0.001 for all analyses. Conclusion: It seems that dyspnea descriptors along with other findings from history and physical examination could be helpful in differentiating the causes of the symptom in patients presenting to ED suffering from dyspnea.

Rumination to negative affect has been linked to the onset and maintenance of mood disorders in adults as well as children. Responses to positive affect have received far less attention thus far. A few recent studies in adults suggest that responses to positive affect are involved in the development of both depressive and hypomanic symptoms, but thus far no study has investigated their role in childhood mood problems. The purpose of the present study was to validate a child version of the Responses to Positive Affect questionnaire and examine the extent to which responses to positive affect prospectively predict mood symptoms over a 3-month interval. The Responses to Positive Affect questionnaire for Children was found to assess two types of responses to positive affect: Positive Rumination and Dampening. Both subscales showed sufficient internal consistency and moderate stability over a 3-month interval. Low levels of positive rumination and high levels of dampening were concurrently associated with depressive symptoms, over and above responses to negative affect. Importantly, low levels of positive rumination also predicted increases in depressive symptoms over a 3-month interval over and above baseline symptoms in children reporting high levels of stress. Both positive rumination and dampening were positively related to concurrent hypomanic symptoms and high levels of positive rumination predicted increases in hypomanic symptoms over a 3-month interval over and above baseline symptoms in children reporting high levels of stress. The results underscore the added value of assessing responses to positive affect in addition to responses to negative affect.

Full Text Available Primary obesity and psychotic disorders are similar with respect to the associated changes in energy balance and co-morbidities, including metabolic syndrome. Such similarities do not necessarily demonstrate causal links, but instead suggest that specific causes of and metabolic disturbances associated with obesity play a pathogenic role in the development of co-morbid disorders, potentially even before obesity develops. Metabolomics – the systematic study of metabolites, which are small molecules generated by the process of metabolism – has been important in elucidating the pathways underlying obesity-associated co-morbidities. This review covers how recent metabolomic studies have advanced biomarker discovery and the elucidation of mechanisms underlying obesity and its co-morbidities, with a specific focus on metabolic syndrome and psychotic disorders. The importance of identifying metabolic markers of disease-associated intermediate phenotypes – traits modulated but not encoded by the DNA sequence – is emphasized. Such markers would be applicable as diagnostic tools in a personalized healthcare setting and might also open up novel therapeutic avenues.

Full Text Available Objective: Few empirical studies have examined the feasibility of trauma-focused treatment among individuals with schizophrenia. This lack of research is important given the substantial overlap of trauma exposure and subsequent PTSD with psychotic spectrum disorders, and the potential for PTSD to complicate the course and prognosis of schizophrenia and other variants of severe mental illness.Method: As part of a larger study, 14 veterans with a psychotic spectrum disorder were enrolled to receive prolonged exposure (PE for PTSD within a single arm open trial study design. Patient reactions and responses to PE were examined using feasibility indices such as attrition, survey reactions, and treatment expectancy; pre and post-changes in PTSD severity and diagnostic status; and thematic interviews conducted post-intervention.Results: Quantitative and qualitative data indicate that implementation of PE is feasible, subjectively well-tolerated, and may result in clinically significant reductions in PTSD symptoms in patients with psychotic spectrum disorders.Conclusion: Consistent with treatment outcome data in clinical populations with a broader range of severe mental illnesses, the current results support the use of PTSD exposure-based interventions, such as PE, for individuals with psychotic spectrum disorders.
Full Text Available Objectives: to analyze changes in psychotic vulnerability following the implementation of a program of prison psychiatric treatment, recidivism after the release and various descriptive variables of criminological interest. Materials and methods: review of a sample consisting of 50 patients diagnosed with schizophrenia admitted to the Prison Psychiatric Hospital of Seville. Results: there was a statistically significant reduction of psychotic vulnerability according to an assessment using the Frankfurt psychopathological inventory (FBF-3, after conducting a complete psychiatric, psychological, social and rehabilitation approach in the prison environment. The core symptoms relating to complex perception and language also decreased significantly. The reduction is particularly noticeable in the number of patients categorized as medium-high and high severity. Recidivism in the follow-up of release of patients in the study sample is low (6% and there were no cases of serious felony or grievous bodily harm. Recidivism, when it occurs, is not immediate. Although there is some criminal versatility, it is limited. The most frequent victims are parents with a previous relationship with the patient. Most of the patients in the sample, and all recidivists, have comorbid substance abuse (dual diagnosis. Discussion: we need more comprehensive studies to establish causal relationships between the decrease in psychotic vulnerability and an integrated psychiatric, psychological, social and rehabilitation approach in prisons; or to attribute the low rate of recidivism to the decline of psychotic vulnerability.

BACKGROUND: Telephone consultation and triage are used to limit the workload on emergency departments. Lack of visual cues and clinical tests put telephone consultations to a disadvantage compared to face-to-face consultations increasing the risk of under-triage. Under-triage occurs in telephone...... triage; however why under-triage happens is not explored yet. The aim of the study was to describe situations of under-triage in context, to assess the quality of under-triaged calls, and to identify communication patterns contributing to under-triage in a regional OOH service in the capital region...... (19%), respiratory (15%) and all others (42%). Thematic analysis of the voice logs suggested that inadequate communication and non-normative symptom description contributed to under-triage. DISCUSSION: The incidence of potentially under-triage is low (0.04%). However, the over...

Background and Objectives Post-traumatic stress disorder (PTSD) is overrepresented among cigarette smokers. It has been hypothesized that those with PTSD smoke to alleviate negative affect and counteract deficient positive affect commonly associated with the disorder; however, limited research has examined associations between PTSD symptoms, smoking motives, and affective vulnerability factors. In the current study, we examined (1) whether PTSD symptoms were associated with positive reinforcement and negative reinforcement smoking motives; and (2) whether two affective vulnerability factors implicated in PTSD—anxiety sensitivity and anhedonia—mediated relationships between PTSD symptoms and smoking motives. Methods Data were drawn from a community sample of non-treatment-seeking smokers recruited without regard for trauma history (N = 342; 10+cig/day). We used the Posttraumatic Stress Disorder Checklist-Civilian Version (PCL-C) to assess overall PTSD symptom severity as well as individual PTSD subfactors. Results Overall, PTSD symptom severity was significantly associated with negative reinforcement, but not positive reinforcement, smoking motives. Variation in anxiety sensitivity significantly mediated the relation between PTSD symptom severity and negative reinforcement smoking motives, whereas anhedonia did not. Regarding PTSD subfactors, emotional numbing was the only PTSD subfactor associated with smoking rate, while re-experiencing symptoms were uniquely associated with both positive reinforcement and negative reinforcement smoking motives. Conclusions and Scientific Significance Findings suggest that anxiety sensitivity may be an important feature associated with PTSD that enhances motivation to smoke for negative reinforcement purposes. Smoking cessation interventions that alleviate anxiety sensitivity and enhance coping with negative affect may be useful for smokers with elevated PTSD symptoms. PMID:25823634

Medically unexplained symptoms are abundantly present in the general population. Stress may lead to increased symptom reporting because of widespread beliefs that it is dangerous for one's health. This study aimed at clarifying the role of stress beliefs in somatic symptom reporting using a quasi-experimental study design. Two hundred sixteen German university students (60 % of an initial sample of 363) were examined at the beginning of the term (less stressful period) and at the end of the term (stressful period due to exams). Negative beliefs about stress at baseline were expected to predict somatic symptoms at follow-up. Negative beliefs about stress at baseline significantly predicted somatic symptoms at follow-up (β = 0.16, p = .012), even when controlling for general strain, physical and mental health status, neuroticism, optimism, and somatosensory amplification. Being convinced that "stress is bad for you" was prospectively associated with somatic symptoms during a stressful period. Further research in patients with medically unexplained conditions is warranted to corroborate these findings.

This study assessed bias in selective attention to facial emotions in negative symptoms of schizophrenia and its influence on subsequent memory for facial emotions. Thirty people with schizophrenia who had high and low levels of negative symptoms (n = 15, respectively) and 21 healthy controls completed a visual probe detection task investigating selective attention bias (happy, sad, and angry faces randomly presented for 50, 500, or 1000 ms). A yes/no incidental facial memory task was then completed. Attention bias scores and recognition errors were calculated. Those with high negative symptoms exhibited reduced attention to emotional faces relative to neutral faces; those with low negative symptoms showed the opposite pattern when faces were presented for 500 ms regardless of the valence. Compared to healthy controls, those with high negative symptoms made more errors for happy faces in the memory task. Reduced attention to emotional faces in the probe detection task was significantly associated with less pleasure and motivation and more recognition errors for happy faces in schizophrenia group only. Attention bias away from emotional information relatively early in the attentional process and associated diminished positive memory may relate to pathological mechanisms for negative symptoms.

Genetic variation in AKT1 may be associated with sensitivity to the psychotomimetic effects of cannabis as well as with increased risk for psychotic disorder following cannabis use. Investigation of the effect of this interaction on relevant intermediate phenotypes for psychosis, such as cognition, may help to clarify the underlying mechanism. Thus, verbal memory (visually presented Word Learning Task), sustained attention (Continuous Performance Test, CPT), AKT1 rs2494732 genotype, and cannabis use were examined in a large cohort of patients with psychotic disorder. No evidence was found for AKT1 × cannabis interaction on verbal memory. Cannabis use preceding onset of psychotic disorder did interact significantly with AKT1 rs2494732 genotype to affect CPT reaction time (β=8.0, SE 3.9, p=0.037) and CPT accuracy (β=-1.2, SE 0.4, p=0.003). Cannabis-using patients with the a priori vulnerability C/C genotype were slower and less accurate on the CPT, whereas cannabis-using patients with the T/T genotype had similar or better performance than non-using patients with psychotic disorder. The interaction was also apparent in patients with psychotic disorder who had not used cannabis in the 12 months preceding assessment, but was absent in the unaffected siblings of these patients and in healthy controls. In conclusion, cannabis use before onset of psychosis may have long-lasting effects on measures of sustained attention, even in the absence of current use, contingent on AKT1 rs2494732 genotype. The results suggest that long-term changes in cognition may mediate the risk-increasing effect of the AKT1 × cannabis interaction on psychotic disorder.

Emerging integrative metacognitive therapies for schizophrenia seek to promote subjective aspects of recovery. Beyond symptom remission, they are concerned with shared meaning-making and intersubjective processes. It is unclear, however, how such therapies should understand and respond to psychotic content that threatens meaning-making in therapeutic contexts. Accordingly, we sought to understand what factors precede and potentially trigger psychotic content within psychotherapy and what aids in resolution and return to meaning-making. Forty-eight transcripts from a single psychotherapy case were analyzed with thematic analysis. Passages of delusional or disorganized content were identified and themes present prior to the emergence and resolution of such material were identified and coded. Themes that preceded the emergence of psychotic content varied across early, middle, and late phases of therapy. Material related to the patient's experience of inadequacy and potential vulnerability, therapist setting boundaries within the therapeutic relationship and making challenges appeared to trigger psychotic content, especially early in treatment. Psychotic content may emerge in session following identifiable antecedents which change over phases of therapy. Attending to psychotic content by assuming a non-hierarchical stance and not dismissing psychotic content may aid in maintaining intersubjectivity and support patient's movements toward recovery in integrative metacognitive therapies.

The influence of cannabis abuse on the severity of existing psychotic and affective symptoms is still unclear. Among 470 consecutively admitted psychotic or affective patients, 54 active (in the previous month) cannabis abusers were detected via urine tests (Sure Step TM kits; Applied Biotech Inc, San Diego, Calif) and Structured Clinical Interview for DSM-IV (SCID- IV) questionnaire. In 24 cases, substances other than cannabis were abused; 392 patients were nonabusers. All patients were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, criteria. The following rating scales were used: Hamilton Depression Rating Scale (HAM-D-21), Positive and Negative Syndrome Scale (PANSS), and Young Mania Rating Scale (YMRS). Cannabis abusers (n = 54) were significantly younger and more frequently males than nonuser patients. In this group, there were more schizophrenic patients and fewer affective and anxiety patients (chi(2) = 11.76; P anxiety, somatic concern, guilt feelings, tension, motor retardation, and volition disturbances. Rates of PANSS negative scale of abusers and nonusers were not significantly different (13.815 +/- 6.868 vs 14.983 +/- 6.446) except for lower rates of social withdrawal and stereotyped thinking for abusers. No significant difference in general level of manic symptoms (YMRS) between abusers and nonusers was observed (6.778 +/- 10.826 vs 4.910 +/- 7.754), but severity of thought/language disturbances and poor insight was found significantly higher in the abusers. Cannabis abusers are obviously less depressive (HAM-D): 5.944 +/- 10.291 vs 12.896 +/- 13.946 (P Cannabis possibly produces some antidepressive and anxiolytic effect on psychotic and affective inpatients. The "price" of this effect is often an exacerbation of psychotic and some manic symptoms.

The concept of prodromal symptoms of schizophrenia has frequently been subject to debate. Authors widely admit the existence of early specific and non-specific signs preceding the first psychotic episode; however, they have yet to clearly demonstrate their ability to predict and specify the outbreak of a psychosis. These prodromal symptoms consist of behavioral abnormalities, pseudo-neurotic signs, subtle cognitive and affective changes. All these symptoms vary from patient to patient. In general, it is widely believed that future patients go through a variety of abnormal, subjective experiences that progressively develop during their pre-puberty and puberty periods. However, the limit of this assessment is that an individual could present the same prodromal symptoms without necessarily developing a psychotic illness, as a result of toxic intake, a situational crisis, etc. Furthermore, while the prodrome is a retrospective concept, its value and specificity can only be prospective, given that patients' descriptions of pre-morbid changes may be corrupted by inefficient memory reconstruction. DSM III-R included prodromal symptoms; individual presenting such symptoms would potentially present psychopathological vulnerability to psychosis regardless of associated genetic risk. Several investigations have shed doubts on their measurement's reliability; therefore, this classification is no longer present in the latest version (DSM IV). Moreover, recent neurodevelopemental hypothesis on schizophrenia have paved the way for possible early intervention, especially because early treatments could well improve illness prognosis. This viewpoint is reinforced by the improved tolerance of new anti-psychotic treatment. In this report, we review the key Articles published over the last 15 Years on this matter. We distinguish two schools of thought: on one hand, the German school referring to the validity of particular neuro-psychological symptoms: attention, perception

Substances such as alcohol, cocaine, amphetamine, and cannabis can produce psychotic reactions in individuals who are otherwise free of serious mental illness. However, persons with primary psychotic disorders, such as schizophrenia and bipolar disorder, who use these substances often present for treatment with signs and symptoms similar to those whose psychosis resulted from the use of drugs alone. While it is often difficult to distinguish substance-induced from primary psychoses, especially early in the course of treatment, this differential diagnosis has important implications for treatment planning. To help clinicians distinguish these two types of presentations, the authors first review the types of psychotic symptoms that can co-occur with substance use. They discuss the prevalence and patterns of substance use that have been found in patients with schizophrenia and other primary psychotic disorders and review the negative outcomes associated with substance use in this population. The prevalence of and types of symptoms and problems associated with psychotic symptoms that occur as a result of substance use alone are also reviewed. The authors describe assessment procedures for differentiating substance-induced and primary psychotic disorders. They stress the importance of accurately establishing the temporal relationship between the substance use and the onset and continuation of psychotic symptoms in making a differential diagnosis, as well as the importance of being familiar with the types of psychological symptoms that can occur with specific substances. The authors review the utility and limitations of a number of diagnostic instruments for assessing patients with co-occurring psychosis and substance use problems, including The Addiction Severity Index, The Michigan Alcohol Screening Test, and diagnostic interviews such as the Schedule for Affective Disorders and Schizophrenia and the Structured Clinical Interview for DSM. They then discuss the

Studies suggest associations between childhood autistic traits and adolescent psychotic experiences. However, recent research suggests that a general neuropsychiatric problems factor predicts adverse outcomes better than specific diagnostic entities. To examine if the alleged association between autistic traits and psychotic experiences could rather be explained by a general neuropsychiatric problems factor comprising symptoms of ADHD, tic disorder, developmental coordination disorder, and learning disorder, we conducted a prospective cohort study based on the Child and Adolescent Twin Study in Sweden. In addition, we examined the genetic and environmental influences on the associations. A total of 9,282 twins with data on childhood autistic traits and other neuropsychiatric problems, and follow-up data on psychotic experiences at ages 15 and/or 18 years were included. First, psychotic experiences were regressed on autistic traits and second, the general neuropsychiatric problems factor was added to the model. Auditory hallucinations were analyzed separately from the other psychotic experiences. Finally, twin analyses were employed to disentangle genetic from environmental influences in the observed associations. Replicating prior research, significant associations were found between autistic traits in childhood and auditory hallucinations at ages 15 and 18. However, after controlling for the general neuropsychiatric problems factor, the associations between autistic traits and auditory hallucinations disappeared, whereas the association between the general neuropsychiatric problems factor and auditory hallucinations persisted after controlling for autistic traits. Twin analyses revealed that the association between the general neuropsychiatric problems factor and auditory hallucinations was driven by shared genetic influences. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

Full Text Available Abstract Background Patients suffering from psychotic disorders have an increased risk of comorbid somatic diseases such as cardiovascular disorders and diabetes mellitus. Doctor-related factors, such as unfamiliarity with these patients, as well as patient-related factors, such as cognitive disturbance and negative symptoms, contribute to suboptimal health care for these patients. General practitioners (GPs could play a key role in diagnosing and treating this somatic comorbidity as in the Netherlands, almost all residents are registered at a general practice. This study aims to find out whether there are any differences between the levels of health care provided by GPs to patients with psychotic disorders, compared to other types of patients. Methods A cohort of patients with an ICPC code of psychosis and two matched control groups, one consisting of patients with other mental problems and the other one of patients without any mental problems, were followed over a period of 5 years. Results Patients with psychotic disorders (N = 734 contacted the GP practice more often than patients in the control groups. These patients, both adults (p = 0.051 and the elderly (p 65 years old (p = 0.007. With regard to chronic illnesses, elderly psychosis patients had fewer contacts related to cardiovascular diseases or chronic lung diseases. Conclusion Patients with psychotic disorders contact the GP practice more frequently than other types of patients. Adult psychosis patients with diabetes mellitus, cardiovascular diseases or chronic lung diseases receive the same amount of health care for these diseases as other primary care patients. The finding that older patients with psychotic disorders are diagnosed with cardiovascular diseases and obstructive lung diseases less frequently than other types of elderly patients requires further study.

Psychotic spectrum disorders present treatment challenges for patients, families, and clinicians. This article addresses the history of the dualism in the field between biological and psychological approaches to mental disorders, and surveys the contemporary literature about the etiology and treatment of psychotic spectrum disorders. An integrative approach to treatment derived from work at Austen Riggs with previously treatment refractory patients with psychotic spectrum disorders is described that combines individual psycho- dynamic psychotherapy, psychopharmacology, family systems approaches, and intensive psychosocial engagement. Helping patients develop their own authority to join the treatment, use relationships for learning, and understand the meaning of their symptoms is central to the treatment at Austen Riggs. An extended case vignette of a patient diagnosed with a schizoaffective disorder is presented illustrating this integrative psychodynamic treatment approach.
Conclusion: This study suggests that the presence of Chiari I malformation in a patient conceals the symptoms of PTC which may become apparent following posterior decompression surgery. Other possibilities could be that the patients are misdiagnosed for Chiari I malformation when they are in fact suffering from PTC, or that PTC is a complication of surgery.

In clinical populations paranoid delusions are associated with making global, stable and external attributions for negative events. Paranoia is common in community samples but it is not known whether it is associated with a similar cognitive style. This study investigates the association between cognitive style and paranoia in a large community sample of young adults. 2694 young adults (mean age 17.8, SD 4.6) from the ALSPAC cohort provided data on psychotic experiences and cognitive style. Psychotic experiences were assessed using a semi-structured interview and cognitive style was assessed using the Cognitive Styles Questionnaire-Short Form (CSQ-SF) on the same occasion. Logistic regression was used to investigate associations between paranoia and CSQ-SF scores, both total and domain-related (global, stable, self, external). The role of concurrent self-reported depressive symptoms in the association was explored. Paranoia was associated with Total CSQ-SF scores (adjusted OR 1.69 95% CI 1.29, 2.22), as well as global (OR 1.56 95% CI 1.17, 2.08), stable (OR 1.56 95% CI 1.17, 2.08) and self (OR 1.37 95% CI 1.05, 1.79) domains, only Total score and global domain associations remained after additional adjustment for self-reported depression. There was no association between paranoia and external cognitive style (OR 1.10 95% CI 0.83, 1.47). Paranoid ideation in a community sample is associated with a global rather than an external cognitive style. An external cognitive style may be a characteristic of more severe paranoid beliefs. Further work is required to determine the role of depression in the association between cognitive style and paranoia.

In recent years, research on psychological processes has greatly advanced our understanding of various psychopathologies. Defense mechanisms, for example, have been described as observable phenomena, and studies have shown meaningful relationships among these processes and other measurable dimensions of health and illness. Despite some notable exceptions, one area that has been overlooked is the empirical study of defenses in psychotic disorders. This is in part due to the lack of valid instruments measuring psychotic-level defenses. Propadeutic to creating an empirical scale for measuring psychotic defenses, the psychoanalytic and empirical literature on psychotic defenses is reviewed, after which the concept of psychotic defenses as measured by the P-DMRS (Psychotic-Defense Mechanism Rating Scales)--which can be used independently or in combination with the current DMRS (Defense Mechanism Rating Scales)--is operationalized. Finally, current research directions applying the P-DMRS to the clinical setting are presented, as well as its implications for guiding current clinical practice.
A comprehensive literature stresses a high percentage of severe childhood maltreatment in the history of many psychotically ill patients treated in mental health services. Early childhood abuse seems to be associated among other things with a more severe clinical state, a more chronic course of illness and a more unfavourable psychosocial adaptation. In order not to jump to unwarranted causal conclusions, several conceptual und methodological problems have to be clarified before. From a conceptual perspective psychotic disorders diagnosed according to conventional criteria define only a minor subgroup within a much broader psychosis continuum in general population. Early childhood abuse has to be differentiated according to type, severity, timing, and context. The rates of early childhood abuse are high in general population. The methods of measurement of psychotic symptoms on the one side, of early trauma on the other side have to be critically evaluated. There is an empirically well founded association of childhood maltreatment and psychological and psychosomatic morbidity during adult years in general. In order to establish a potential conditional link also to psychotic disorders, clinical populations have to be compared to adequate control groups at least. A systematic literature search shows a very small number of studies including control groups at all. These studies underline that early childhood abuse may be significantly associated to the risk of psychosis indeed. The conditional role of early childhood abuse, however, has to be investigated only within a multifactorial biopsychosocial model of psychotic illness.

Psychiatric disorders have been reported in over 10% of patients with velo-cardio-facial syndrome (VCFS) in long-term follow-up. To further explore the behavioral and psychiatric findings associated with VCFS in adulthood, detailed clinical histories of two patients - one with VCFS who developed a psychotic illness, and one with schizophrenia who was found to have dysmorphological features associated with VCFS - are described in the current report. The observed overlap of physical and psychiatric symptoms in these two patients suggests that VCFS and psychotic disorders may share a pathogenetic mechanism. This could be consistent with a contiguous gene model for VCFS and psychosis, suggesting chromosome 22q11 as a possible candidate region for genetic studies of schizophrenia. 26 refs., 2 tabs.

Valid instruments for the early identification of psychotic experiences (PE) and symptoms in youths are urgently needed for large-scale preventive interventions. A new section of The-Development-and-Well-Being Assessment (DAWBA) measuring child self-reported PE has yet to be validated. The current study aimed to investigate the concurrent validity of DAWBA-based self-reported PE (PE-S) with regard to interview-based measures of PE (PE-I). Participants were 1571 (47.8% male) children of age 11 to 12 years from the Copenhagen Child Cohort 2000 (CCC2000) with complete data from both the online PE-section of DAWBA and the following face-to-face interview and assessment of PE. The DAWBA-PE-section asks the child 10 questions covering auditory and visual hallucinations, delusional ideas and subjective thought disturbances ever in life; and attributions to sleep, fever, illness or drug intake. The interview-based assessment of PE was performed by trained professionals using 22 items from The Schedule for Affective Disorders and Schizophrenia for School Aged Children-Present and Lifetime Version (KSADS-PL). The two assessments were completed independently. The prevalence of PE-S was 28.1% (24.3% for PE-S with no frequent attributions), compared with 10.2% for PE-I. The predictive values of PE-S for any PE-I were: sensitivity = 73.8%, specificity = 77.1%, positive predictive value (PPV) = 26.8% and negative predictive value (NPV) = 96.3%. Self-reported visual hallucinations had the best overall predictive values with a sensitivity of 43.1%, specificity of 94.0%, PPV of 44.8% and a NPV of 93.6% for any PE-I. The DAWBA-section proved valuable as a screening tool for PE in the youth general population. © 2018 John Wiley & Sons Australia, Ltd.

Initiating psychiatric treatment depends on several factors including clinical, personal, familial and economic factors. In the case of a first psychotic episode in an adolescent, parents, especially mothers, have a critical role in initiating psychiatric treatment for their child. In this study, we investigated mothers' beliefs about their child's first psychotic episode. Participants were adolescents consulting the department of Child and Adolescent Psychiatry of the Razi hospital in Tunisia. They were aged from 12 to 19 years at the onset of their medical follow-up. Their diagnoses were schizophrenia, schizoaffective disorder and schizophreniform disorder according to DSM-IV. A questionnaire was submitted to patients' mothers after their approval. It was divided into two parts. The first part was used to collect information on socio-demographic and clinical characteristics of the mothers and their children. The second part was composed of the following four questions in Tunisian dialect: (1) what did you think was the matter when you first noticed psychotic symptoms in your child? (2) what was the main reason for which you thought psychiatric treatment was necessary? (3) what obstacles did you perceive in initiating psychiatric treatment? (4) do you have any advice or suggestions for caregivers on how they could facilitate an early start of treatment? Twenty-two mothers were included. The mean age of the mothers at onset of the follow-up of their child was 42 years (SD: 4.81). Ten mothers had never been schooled, five had primary school level, four had secondary school level, three had bachelor's degree and two had a diploma of doctorate; 63.6% of the mothers were housewives. The mean age of patients was 13.77 years at the start of their medical follow-up (SD= ± 2.14). Most of the patients were male (14 males for eight girls). Most patients were diagnosed as having schizophrenia (91%); 4.5% were diagnosed with schizoaffective disorder and 4.5% with

An experimental design was used to test whether self-reported, psychophysiological and symptomatic stress-responses increase as a function of the underlying vulnerability to psychosis as proposed by vulnerability-stress-models. Stress-responses of participants with psychotic disorders (PSY, n = 35) were compared to those of participants with attenuated positive symptoms (AS, n = 29), first-degree relatives of persons with psychotic disorders (REL, n = 26), healthy controls (HC, n = 28) and controls with depression (DEP, n = 30). Using a repeated measures design, participants were assigned to a noise stressor, a social stressor and a no stress condition in random order. Stress-responses were assessed via self-report, salivary cortisol levels, heart rate and skin conductance levels. State-paranoia and depression were assessed with clinical scales. PSY reported to be significantly more stressed than HC, AS and REL across all conditions which went along with increased heart rate and decreased overall cortisol release. In contrast, AS showed elevated levels of cortisol. PSY showed a stronger response of self-reported stress to the noise condition compared to the no stress condition than HC, but no stronger response than the other samples. Furthermore, the stressors did not trigger stronger psychophysiological responses or symptom-increases in PSY. The social stressor was brief and not individualized and did not have an effect on cortisol. The findings support the notion that subjective stress-responsiveness increases with vulnerability, but not the assumption that symptoms arise directly as a function of stress and vulnerability. Also, the generally high levels of arousal seem to be more relevant to psychosis than the responsiveness to specific stressors. Copyright © 2014 Elsevier Ltd. All rights reserved.

The aim of this study was to investigate the relationship between stroke lesion location and the resulting somatosensory deficit. We studied exteroceptive and proprioceptive somatosensory symptoms and stroke lesions in 38 patients with first-ever acute stroke. The Erasmus modified Nottingham Sensory Assessment was used to clinically evaluate somatosensory functioning in the arm and hand within the first week after stroke onset. Additionally, more objective measures such as the perceptual threshold of touch and somatosensory evoked potentials were recorded. Non-parametric voxel-based lesion-symptom mapping was performed to investigate lesion contribution to different somatosensory deficits in the upper limb. Additionally, structural connectivity of brain areas that demonstrated the strongest association with somatosensory symptoms was determined, using probabilistic fiber tracking based on diffusion tensor imaging data from a healthy age-matched sample. Voxels with a significant association to somatosensory deficits were clustered in two core brain regions: the central parietal white matter, also referred to as the sensory component of the superior thalamic radiation, and the parietal operculum close to the insular cortex, representing the secondary somatosensory cortex. Our objective recordings confirmed findings from clinical assessments. Probabilistic tracking connected the first region to thalamus, internal capsule, brain stem, postcentral gyrus, cerebellum, and frontal pathways, while the second region demonstrated structural connections to thalamus, insular and primary somatosensory cortex. This study reveals that stroke lesions in the sensory fibers of the superior thalamocortical radiation and the parietal operculum are significantly associated with multiple exteroceptive and proprioceptive deficits in the arm and hand.

Full Text Available OBJECTIVE: Evaluation of the clinical signs and symptoms predicting bacterial and viral pneumonia, in accordance with the Brazilian National Control Program for Acute Respiratory (ARI. METHODS: Observational prospective study. Seventy-six children from birth to six months of age who had pneumonia were studied in the emergency room. The patients were subdivided into two groups, based on radiological findings (gold-standard: 47 had bacterial pneumonia, and 29 had viral pneumonia. The frequencies, sensitivities, and specificities of the signs and symptoms were evaluated. RESULTS: The sensibilities and sensitivities of general findings in bacterial pneumonia were, respectively: fever 53.2%/40.0%; hypoactivity 68.4%/55.6% and prostration detected by the doctor 72.7%/55.0%. The same findings in viral pneumonias showed, respectively: 37.9%/40.0%, 66.7%/55.6% and 66.7%/55.6%. The sensibilities and sensitivities of respiratory findings in bacterial pneumonia were, respectively: coughing 66.0/38.1%, Respiratory rate = 50 ripm 76.6%/38.1%, altered respiratory auscultation 91.3%/10.5%, and chest indrawing 46.7%/80.0%. The same findings in viral pneumonias were, respectively: 69.0%/38.1%, 86.2%/38.1%, 85.7%/10.5% and 44.8%/80.0%. CONCLUSION: Analysis of signs and symptoms in each group did not distinguish bacterial from viral pneumonia. Our findings reinforce the adequacy of the ARI program in Brazil, which gives an early diagnosis of pneumonia, independent of its etiology.

Suicides of patients in states of acute persecutory panic may be provoked by a subjective experience of helpless terror threatening imminent annihilation or dismemberment. These patients are literally scared to death and try to run away. They imagine suicide is survivable and desperately attempt to escape from imaginary enemies. These states of terror occur in a wide range of psychotic illnesses and are often associated with command hallucinations and delusions. In this article, the authors consider the subjective experience of persecutory panic and the suicide response as an attempt to flee from danger.

Quetiapine is an atypical antipsychotic agent that does not appear to increase patient risk for treatment-emergent extrapyramidal symptoms (EPS) or anticholinergic symptoms. Previous studies of quetiapine use in elderly patients with schizophrenia and other psychoses examined short-term administration (safety, and clinical benefit of quetiapine in elderly patients with psychosis. Elderly patients (> or = 65 years of age) with psychotic disorders, as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, participated in this 52-week, open-label, multicenter trial. Investigators increased (and later adjusted) daily doses of quetiapine on the basis of clinical response and tolerability, and assessed safety and efficacy. Efficacy assessments were made using the 18-item Brief Psychiatric Rating Scale (BPRS), Clinical Global Impressions (CGI), Simpson-Angus Scale, and the Abnormal Involuntary Movement Scale (AIMS). For patients who withdrew before week 52, analyses were performed using observed data and the last observation carried forward. One hundred eighty-four patients with psychotic disorders (98 women and 86 men) with a mean age of 76.1 years entered the trial. Seventy-two percent had psychotic disorders due to general medical conditions such as Alzheimer's disease, and 28% had other psychotic disorders, most commonly schizophrenia. Overall, 89 (48%) patients completed treatment through 52 weeks. Median total daily dose was 137.5 mg. Reasons, for withdrawal included lack of efficacy (19%), adverse events or intercurrent illness (15%), failure to return for follow-up (13%), protocol noncompliance (3%), and diminished need for treatment (2%). Somnolence (31%), dizziness (17%), and postural hypotension (15%) were common adverse events, but they rarely resulted in withdrawal from therapy. EPS-related adverse events occurred in 13% of patients. At end point (week 52), mean total score on the Simpson-Angus Scale had decreased from baseline

Full Text Available A 21-year-old female patient with abdominal pain, vomiting and constipation was admitted to the hospital with the possible diagnosis of diabetic ketoacidosis. Due to increased abdominal pain and constipation the patient underwent a surgery with the diagnosis of ileus. However, no pathological findings were found in the abdominal organs apart from serous fluid in the abdominal cavity. The patient became hypertensive, tachycardic and had an episode of seizures postoperatively. Neurological manifestations with unexplained abdominal pain indicated a diagnosis of acute intermittent porphyria (AIP. Acute intermittent porphyria diagnosis is based on elevated urinary δ-aminolevulinic acid (ALA and porphobilinogen (PBG levels as well as hydroxymethylbilane synthase (HMBS IVS13-2 A>G heterozygous mutation. Familial Mediterranean Fever (FMF gene mutations were not confirmed. Porphyria should be considered in the differential diagnosis of patients with recurrent abdominal pain, neurological symptoms and lack of FMF gene polymorphism.

The author tries to differentiate intuitive imagination from delusional imagination and hypothesises that psychosis alters the system of intuitive thinking, which consequently cannot develop in a dynamic and selective way. Scholars of different disciplines, far removed from psychoanalysis, such as Einstein, Hadamard or Poincaré, believe that intuitive thinking works in the unconscious by means of hidden processes, which permit a creative meeting of ideas. Thanks to Bion's work, psychoanalysts have begun to understand that waking thinking is unconsciously intertwined with dream-work. The delusional construction is similar to a dreamlike sensorial production but, unlike a real dream, it remains in the waking memory and creates characters which live independently of the 'dreamer's' awareness. It is a dream that never ends. On the contrary, the real dream disappears when it has brought its communicative task to an end. In the analysis of psychotic patients it is very important to analyse the delusional imagination which dominates the personality and continuously transforms the mental state, twisting emotional truth. The delusional imagination is so deeply rooted in the patient's mental functioning that, even after systematic analysis, the delusional world, which had seemed to disappear, re-emerges under new configurations. The psychotic core remains encapsulated; it produces unsteadiness and may induce further psychotic states in the patient. The author reports some analytic material of a patient, who, after a delusional episode treated with drugs, shows a vivid psychotic functioning. Some considerations are added on the nature of the psychotic state and on the therapeutic approach used to transform the delusional structure. This paper particularly deals with the difficulty in working through the psychotic episode and in 'deconstructing'the delusional experience because of the terror connected with it. In the reported case, the analytic work changed the delusional
Full Text Available BACKGROUND Dry eye disease is a well-known side effect of antipsychotic therapy which is often neglected due to nonspecific symptoms. Therefore, this study is to analyse tear film dysfunction in patients on chronic antipsychotic therapy. MATERIALS AND METHODS Study was undertaken on 200 eyes of 100 patients who were on chronic anti-psychotic therapy attending the Psychiatry OPD. Out of 100 patients, 65 patients were male, rest 35 were females. Ocular examination was done on all patients which included BCVa, slit lamp evaluation and dry eye evaluation. RESULTS 32 out of 100 patients on chronic anti-psychotic therapy had dry eye disease. 17 (53.13% out of these 32 patients had symptoms suggestive of dry eye disease. Patients on typical antipsychotics and multidrug regimen showed more prevalence of dry eye. CONCLUSION Nearly 40% patients were in Grade 3 category of dry eye disease, which if not treated on time can lead to further progression and complication of disease. Patients may not come out with symptoms of ocular diseases so it is mandatory to screen these patients to diagnose early and to prevent complications. This study emphasizes on the need to give importance to patients symptoms so that it can be detected earlier before it progresses.
Epidemiological and clinical characterization following a first psychotic episode in major depressive disorder: Comparisons with Schizophrenia and Bipolar I Disorder in the Cavan-Monaghan First Episode Psychosis Study (CAMFEPS).
While recent research on psychotic illness has focussed on the nosological, clinical, and biological relationships between schizophrenia and bipolar disorder, little attention has been directed to the most common other psychotic diagnosis, major depressive disorder with psychotic features (MDDP). As this diagnostic category captures the confluence between dimensions of psychotic and affective psychopathology, it is of unappreciated heuristic potential to inform on the nature of psychotic illness. Therefore, the epidemiology and clinical characteristics of MDDP were compared with those of schizophrenia and bipolar disorder within the Cavan-Monaghan First Episode Psychosis Study (n = 370). Epidemiologically, the first psychotic episode of MDDP (n = 77) was uniformly distributed across the adult life span, while schizophrenia (n = 73) and bipolar disorder (n = 73) were primarily disorders of young adulthood; the incidence of MDDP, like bipolar disorder, did not differ between the sexes, while the incidence of schizophrenia was more common in males than in females. Clinically, MDDP was characterized by negative symptoms, executive dysfunction, neurological soft signs (NSS), premorbid intellectual function, premorbid adjustment, and quality of life similar to those for schizophrenia, while bipolar disorder was characterized by less prominent negative symptoms, executive dysfunction and NSS, and better quality of life. These findings suggest that what we currently categorize as MDDP may be more closely aligned with other psychotic diagnoses than has been considered previously. They indicate that differences in how psychosis is manifested vis-à-vis depression and mania may be quantitative rather than qualitative and occur within a dimensional space, rather than validating categorical distinctions.

Schizophrenia is associated with aberrant event-related potentials (ERPs) such as reductions in P300, processing negativity and mismatch negativity amplitudes. These deficits may be related to the propensity of schizophrenia patients to experience auditory verbal hallucinations (AVH). However, AVH are part of extensive and variable symptomatology in schizophrenia. For this reason non-psychotic individuals with AVH as an isolated symptom provide an excellent opportunity to investigate this relationship. P300 waveforms, processing negativity and mismatch negativity were examined with an auditory oddball paradigm in 18 non-psychotic individuals with AVH and 18 controls. P300 amplitude was increased in the AVH group as compared to controls, reflecting superior effortful attention. A trend in the same direction was found for processing negativity. No significant differences were found for mismatch negativity. Contrary to our expectations, non-psychotic individuals with AVH show increased rather than decreased psychophysiological measures of effortful attention compared to healthy controls, refuting a pivotal role of decreased effortful attention in the pathophysiology of AVH.

A woman in her midtwenties with a history of major depressive disorder and a recent major depressive episode with mood-congruent psychotic features died by suicide. Two weeks before her death, she demonstrated exceptional elevations on the nondisplay of imperfection factor of Hewitt and Flett's Perfectionistic Self-Presentation Scale. Perfectionism and especially perfectionistic self-presentation have been strongly associated with suicide across several populations, accounting for unique variance in suicidality beyond depression and hopelessness. Yet interpersonal facets of perfectionism are not recognized as clinical risk factors for suicide. There is also a paucity of research on perfectionism in relation to psychotic symptoms. This case account illustrates the role of perfectionistic self-presentation in suicides that occur seemingly without warning and, to our knowledge, this is the first examination of perfectionistic self-presentation and suicide in a case where psychotic features occurred. This study, though single case-based, draws attention to perfectionism and perfectionistic self-presentation and their potential roles in suicide, especially when accompanied by other risk factors. Future research in this area may elucidate the role of perfectionism in suicide, singularly and in the context of a comprehensive clinical risk assessment, demonstrating whether perfectionism confers information about suicide risk beyond known clinical risk factors.

The paper presents the results of examination of 110 alcoholic patients who have committed criminal actions and were recognized as irresponsible at forensic examination. It was established that wide spectrum of mental disorders were present in such cases--from superacute psychotic states (15 patients) and acute disorders (49) to chronic psychoses (33) and encephalopathy (13). According to clinical manifestations mental disorders correspond in such cases to reactions of exogenic type. In contrast to general medical departments where patients with alcoholic delirium prevail, the studied sample of patients had primarily psychoses with hallucinative-delirious and delirious disorders. Disorders of personality manifested as typical alcoholic, asthenoneurotic, psychopathic-like, residual-psychotic, psychoorganic changes and partial dementia (19 cases).

This article is part of a Special Issue "Puberty and Adolescence". The notion that adolescence is characterized by dramatic changes in behavior, and often by emotional upheaval, is widespread and longstanding in popular western culture. In recent decades, this notion has gained increasing support from empirical research showing that the peri- and post-pubertal developmental stages are associated with a significant rise in the rate of psychiatric symptoms and syndromes. As a result, interest in adolescent development has burgeoned among researchers focused on the origins of schizophrenia and other psychotic disorders. Two factors have fueled this trend: 1) increasing evidence from longitudinal research that adolescence is the modal period for the emergence of "prodromal" manifestations, or precursors of psychotic symptoms, and 2) the rapidly accumulating scientific findings on brain structural and functional changes occurring during adolescence and young adulthood. Further, gonadal and adrenal hormones are beginning to play a more prominent role in conceptualizations of adolescent brain development, as well as in the origins of psychiatric symptoms during this period (Walker and Bollini, 2002; Walker et al., 2008). In this paper, we begin by providing an overview of the nature and course of psychotic disorders during adolescence/young adulthood. We then turn to the role of hormones in modulating normal brain development, and the potential role they might play in the abnormal brain changes that characterize youth at clinical high-risk (CHR) for psychosis. The activational and organizational effects of hormones are explored, with a focus on how hormone-induced changes might be linked with neuropathological processes in the emergence of psychosis.

We report a successful treatment with lamotrigine of a patient with hereditary coproporphyria presenting with affective and psychotic symptoms. M.F., a 38-year-old, single woman was admitted to an acute psychiatric ward because of suddenly emerging psychosis. Ms F's hereditary coproporphyria was diagnosed 9 years before the current admission. While on treatment with olanzapine (20mg/day) the psychotic symptoms have gradually disappeared. In view of her significant mood fluctuations predominantly with depressed phases, lamotrigine was started and titrated up to 125 mg/day. Ms F's mood gradually became euthymic, suicidal ideations and anxiety disappeared. At 5-month follow-up, while still on lamotrigine, her porphyria was asymptomatic. To the best of our knowledge, this is the first report about the safe administration of lamotrigine in hereditary coproporphyria. Lamotrigine did not trigger an acute porphyric attack as confirmed by clinical and laboratory findings.

Impaired clinical insight (CI) is a common symptom of psychotic disorders and a promising treatment target. However, to date, our understanding of how variability in CI is tied to underlying brain dysfunction in the clinical high-risk period is limited. Developing a stronger conception of this link will be a vital first step for efforts to determine if CI can serve as a useful prognostic indicator. The current study investigated whether variability in CI is related to major brain networks in adolescents and young adults at ultra high-risk (UHR) of developing psychosis. Thirty-five UHR youth were administered structured clinical interviews as well as an assessment for CI and underwent resting-state magnetic resonance imaging scans. Functional connectivity was calculated in the default mode network (DMN) and fronto-parietal network (FPN), two major networks that are dysfunctional in psychosis and are hypothesized to affect insight. Greater DMN connectivity between the posterior cingulate/precuneus and ventromedial prefrontal cortex (DMN) was related to poorer CI (R 2 =0.399). There were no significant relationships between insight and the FPN. This is the first study to relate a major brain network to clinical insight before the onset of psychosis. Findings are consistent with evidence if a hyperconnected DMN in schizophrenia and UHR, and similar to a previous study of insight and connectivity in schizophrenia. Results suggest that a strongly connected DMN may be related to poor self-awareness of subthreshold psychotic symptoms in UHR adolescents and young adults. Copyright © 2017 Elsevier B.V.

Wheat ( Tritium aestivum L.) production is essential for global food security. Infection of barley yellow dwarf virus-GAV (BYDV-GAV) results in wheat showing leaf yellowing and plant dwarfism symptom. To explore the molecular and ultrastructural mechanisms underlying yellow dwarf symptom formation in BYDV-GAV-infected wheat, we investigated the chloroplast ultrastructure via transmission electron microscopy (TEM), examined the contents of the virus, H₂O₂, and chlorophyll in Zhong8601, and studied the comparative transcriptome through microarray analyses in the susceptible wheat line Zhong8601 after virus infection. TEM images indicated that chloroplasts in BYDV-GAV-infected Zhong8601 leaf cells were fragmentized. Where thylakoids were not well developed, starch granules and plastoglobules were rare. Compared with mock-inoculated Zhong8601, chlorophyll content was markedly reduced, but the virus and H₂O₂ contents were significantly higher in BYDV-GAV-infected Zhong8601. The transcriptomic analyses revealed that chlorophyll biosynthesis and chloroplast related transcripts, encoding chlorophyll a/b binding protein, glucose-6-phosphate/phosphate translocator 2, and glutamyl-tRNA reductase 1, were down-regulated in BYDV-GAV-infected Zhong8601. Some phytohormone signaling-related transcripts, including abscisic acid (ABA) signaling factors (phospholipase D alpha 1 and calcineurin B-like protein 9) and nine ethylene response factors, were up-regulated. Additionally, reactive oxygen species (ROS)-related genes were transcriptionally regulated in BYDV-GAV infected Zhong8601, including three up-regulated transcripts encoding germin-like proteins (promoting ROS accumulation) and four down-regulated transcripts encoding peroxides (scavenging ROS). These results clearly suggest that the yellow dwarf symptom formation is mainly attributed to reduced chlorophyll content and fragmentized chloroplasts caused by down-regulation of the chlorophyll and chloroplast biosynthesis

An association between marijuana use and schizophrenia has been noted for decades, and the recent emergence of high-efficacy synthetic cannabinoids (SCBs) as drugs of abuse has lead to a growing number of clinical reports of persistent psychotic effects in users of these substances. The mechanisms underlying SCB-elicited pro-psychotic effects is unknown, but given the ubiquitous neuromodulatory functions of the endocannabinoid system, it seems likely that agonist actions at cannabinoid type-1 receptors (CB1Rs) might modulate the functions of other neurotransmitter systems known to be involved in schizophrenia. The present review surveys what is currently known about the interactions of CB1Rs with dopamine, serotonin, and glutamate systems, because all three of those neurotransmitters are well-established in the pathophysiology of schizophrenia and psychosis. Identification of molecular mechanisms underlying the pro-psychotic effects of SCB drugs of abuse may establish certain classes of these substances as particularly dangerous, guiding regulations to control availability of these drugs. Likewise, an understanding of the pharmacological interactions which lead to schizophrenia and psychosis subsequent to SCB exposure might guide the development of novel therapies to treat afflicted users.

Full Text Available Psychotic Experiences (PEs during adolescence index increased risk for psychotic disorders and schizophrenia in adult life. Working memory (WM deficits are a core feature of these disorders. Our objective was to examine the relationship between PEs and WM in a general population sample of young people in a case control study. 4744 individuals of age 17-18 from Bristol and surrounding areas (UK were analyzed in a cross-sectional study nested within the Avon Longitudinal Study of Parents and Children (ALSPAC birth cohort study. The dependent variable was PEs, assessed using the semi-structured Psychosis-Like Symptom Interview (PLIKSi. The independent variable was performance on a computerized numerical n-back working memory task. Signal-Detection Theory indices, including standardized hits rate, false alarms rate, discriminability index (d' and response bias (c from 2-Back and 3-Back tasks were calculated. 3576 and 3527 individuals had complete data for 2-Back and 3-Back respectively. Suspected/definite PEs prevalence was 7.9% (N = 374. Strongest evidence of association was seen between PEs and false alarms on the 2-Back, (odds ratio (OR = 1.17 [95% confidence intervals (CI 1.01, 1.35] and 3-back (OR = 1.35 [1.18, 1.54] and with c (OR = 1.59 [1.09, 2.34], and lower d' (OR = 0.76 [0.65, 0.89], on the 3-Back. Adjustment for several potential confounders, including general IQ, drug exposure and different psycho-social factors, and subsequent multiple imputation of missing data did not materially alter the results. WM is impaired in young people with PEs in the general population. False alarms, rather than poor accuracy, are more closely related to PEs. Such impairment is consistent with different neuropsychological models of psychosis focusing on signal-to-noise discrimination, probabilistic reasoning and impaired reality monitoring as a basis of psychotic symptoms.

Psychotic disorders, as well as psychotic-like experiences and substance use, have been found to be associated. The main goal of the present study was to analyse the relationship between psychoticlike experiences and substance use in college students. The simple comprised a total of 660 participants (M = 20.3 years, SD = 2.6). The results showed that 96% of the sample reported some delusional experience, while 20.3% reported at least one positive psychotic-like experience. Some substance use was reported by 41.1% of the sample, differing in terms of gender. Substance users reported more psychoticlike experiences than non-users, especially in the positive dimension. Also, alcohol consumption predicted in most cases extreme scores on measures of delusional ideation and psychotic experiences. The association between these two variables showed a differentiated pattern, with a stronger relationship between substance use and cognitive-perceptual psychotic-like experiences. To some extent, these findings support the dimensional models of the psychosis phenotype and contribute a better understanding of the links between psychoticlike experiences and substance use in young adults. Future studies should further explore the role of different risk factors for psychotic disorders and include models of the gene-environment interaction.

Although psychosis often occurs during adolescence, there has been little research on how the ubiquitously used Internet and social media could impact pathways to care. We examined how youth with psychotic spectrum disorders (PSD) versus non-psychotic mood disorders (NPMD) use online resources in the early illness stages. Social media use and pathways to care data were collected using a semi-structured interview from 80 youth (PSD = 40 and NPMD = 40) aged 12-21 years within 2 years of symptom onset. A total of 97.5% of participants (mean age = 18.3 years) regularly used social media, spending approximately 2.6 ± 2.5 h per day online. There were 22.4% of our sample (PSD = 19.4%, NPMD = 25.0%, P = 0.56) who reported waiting to reach out for help believing that symptoms would disappear. A total of 76.5% (PSD = 67.5%, NPMD = 85.0%, P = 0.06) noticed social media habit changes during symptom emergence. Thirty per cent reported discussing their symptoms on social media (PSD = 22.5%, NPMD = 37.5%, P = 0.14). NPMD patients sought information most on how to stop symptoms (40.0% vs. 13.5%, P = 0.01), while PSD youth were more commonly interested in what caused their symptoms (21.6% vs. 15.0%, P = 0.45). More PSD patients (42.9% vs. 25.0%, P = 0.10) would prefer to receive mental health information via the Internet. Altogether, 63.6% (PSD = 64.9%, NPMD = 62.5%, P = 0.83) were amenable to clinicians proactively approaching them via social media during symptom emergence. A total of 74.3% (PSD = 78.4%, NPMD = 70.0%, P = 0.40) liked the idea of obtaining help/advice from professionals via social media. The Internet and social media provide an unparalleled opportunity to supplement and potentially transform early intervention services, and acceptance of this approach appears to be high. © 2015 Wiley Publishing Asia Pty Ltd.

Recent research shows that psychotic symptoms, or psychotic-like experiences (PLEs), are reported not only by psychosis patients but also by healthy members of the general population. Healthy individuals who report these symptoms are considered to represent a non-clinical psychosis phenotype, and have been demonstrated to be at increased risk of schizophrenia-spectrum disorder. Converging research now shows that this non-clinical psychosis phenotype is familial, heritable and covaries with familial schizophrenia-spectrum disorder. A review of the research also shows that the non-clinical phenotype is associated extensively with schizophrenia-related risk factors, including social, environmental, substance use, obstetric, developmental, anatomical, motor, cognitive, linguistic, intellectual and psychopathological risk factors. The criterion and construct validity of the non-clinical psychosis phenotype with schizophrenia demonstrates that it is a valid population in which to study the aetiology of psychosis. Furthermore, it suggests shared genetic variation between the clinical and non-clinical phenotypes. Much remains to be learned about psychosis by broadening the scope of research to include the non-clinical psychosis phenotype.

Rates of the metabolic syndrome in people with psychotic illness are high. Emerging evidence suggests that cannabis use may have a positive impact on cardiometabolic risk factors in the general population, but little is known about its impact for people with psychotic illness. Our aim was to investigate whether the rate of the metabolic syndrome in people with psychotic illness was associated with frequency of cannabis use. The 2010 Australian psychosis survey used a two-phase design to randomly select a nationally representative sample of 1825 adults with psychotic illness for interview and physical assessment. This study is based on 1813 participants who provided data on cannabis use. Multiple logistic regression was used to model the influence of frequency of cannabis use on the metabolic syndrome, adjusting for potential covariates including antipsychotic medication use, smoking, alcohol use and cognitive function. One-third (33.0%) of participants had used cannabis in the past year. The proportion of non-users, occasional users and frequent users with the metabolic syndrome was 63.0, 51.7 and 43.5%, respectively (p cannabis use were associated with significantly lower odds of the metabolic syndrome. In the adjusted analyses, the association between the metabolic syndrome and frequent cannabis use remained significant [odds ratio = 0.56, 95% confidence interval (CI) 0.39-0.80], but not the association with occasional use (odds ratio = 0.75, 95% CI 0.49-1.13). While cannabis use may be detrimental for mental health, these data suggest that it may also have a cardiometabolic protective effect. Further investigation is required to understand the mechanism underlying this paradoxical finding.

The thermoregulatory control of human skin blood flow is vital to maintain the body heat storage during challenges of thermal homeostasis under heat stress. Whenever thermal homeostasis disturbed, the heat load exceeds heat dissipation capacity, which alters the cutaneous vascular responses along with other body physiological variables. Whole body skin blood flow has been calculated from the forearm blood flow. Present model has been designed using electronics circuit simulator (Multisim 8.0, National Instruments, USA), is to execute a series of predictive equations for early prediction of physiological parameters of young nude subjects during resting condition at various level of dry heat stress under almost still air to avoid causalities associated with hot environmental. The users can execute the model by changing the environmental temperature in degrees C and exposure time in minutes. The model would be able to predict and detect the changes in human vascular responses along with other physiological parameters and from this predicted values heat related-illness symptoms can be inferred.

The associations of insight into psychosis (i.e., awareness of illness) with clinical variables have been examined by a great number of studies. Most of these studies revealed that the level of insight is negatively correlated with psychotic symptoms but positively correlated with depression and suicidal ideation. The aim of this study was to test these findings in a Greek sample of patients. Forty-three outpatients (30 men and 13 women) with schizophrenia or delusional disorder being followed up at the Mental Health Centre of Kavala took part in the study. Patients with bipolar or schizoaffective disorder were excluded. Patients' mean age was 40.7 years and the mean duration of illness was 18.67 years. All participants were under treatment and clinically stable at the time of the study. We used the Positive and Negative Syndrome Scale (PANSS) for the assessment of positive and negative symptoms, the Schedule for the Assessment of Insight-Expanded (SAI-E) to assess the insight into psychosis, and the Montgomery-Asberg Depression Rating Scale (MADRS) for the evaluation of depression recording separately the score for item 10 as an estimate of suicidal ideation. All the scales used have been adapted to Greek population. We used Spearman rho coefficient to assess the strength of correlations between the scales because the distributions of some scores were not normal. In order to assess the predictive value of insight for depression and suicidal ideation, we used hierarchical linear regression analysis. Correlation coefficients between SAI-E and the clinical scales of psychopathology, depression and suicide ideation was statistically significant at the pregression analysis showed that our model of positive and negative psychopathology and insight explained 47.4% of the variance of depression and 32.2% of the variance of suicidal ideation. The predictive value of insight was critically important, because only after the introduction of the SAI-E score in the analysis our

Eight patients meeting Leonhard's criteria for cycloid psychosis were investigated on repeated occasions during a psychotic episode, with regional cerebral blood flow measurements and clinical ratings. The results showed that, at admission to the hospital, when the patients were clinically exacerbated, the mean hemispheric blood flow was significantly elevated compared with values from a normal control group. The hemispheric blood flow level covaried significantly with the degree of clinical symptoms, such that the more elevated the cortical blood flow was, the more behaviorally disturbed was the patient. At discharge from the hospital, the patients had no residual symptoms and the cortical blood flow was normal. These findings differ distinctly from those commonly made in other psychoses, such as schizophrenia.

This study aimed to investigate the association of obsessive-compulsive symptoms with clinical and neurocognitive features in patients with schizophrenia. This study enrolled 163 people with schizophrenia who were receiving risperidone monotherapy. Comorbid obsessive-compulsive symptoms were assessed using the Yale-Brown Obsessive-Compulsive Scale, and subjects with a score ≥ 10 constituted the obsessive-compulsive symptom group (n=30, 18.4%). The learning index was significantly higher in patients with obsessive-compulsive symptoms than in those without such symptoms after adjusting for age, stage (early and chronic), duration of illness, and CDSS score. However, there was no significant interaction between obsessive-compulsive symptoms and stage of illness. Scores on Positive and Negative Syndrome Scale, Calgary Depression Scale for Schizophrenia, and Beck Depression Inventory were significantly higher in the obsessive-compulsive symptom group. In addition, the Subjective Well-being under Neuroleptic Treatment score was significantly lower in the obsessive-compulsive symptom group. In conclusion, comorbid obsessive-compulsive symptoms in patients with schizophrenia were associated with a higher learning ability without a significant interaction with stage of illness. However, schizophrenia patients with obsessive-compulsive symptoms had more severe psychotic and depressive symptoms and poorer quality of life. Copyright © 2015 Elsevier Ireland Ltd.

The authors sought to model the different trajectories of psychotic-like experiences (PLE) during adolescence and to examine whether the longitudinal relationship between cannabis use and PLE is mediated by changes in cognitive development and/or change in anxiety or depression symptoms. A total of 2,566 youths were assessed every year for 4-years (from 13- to 16-years of age) on clinical, substance use and cognitive development outcomes. Latent class growth models identified three trajectories of PLE: low decreasing (83.9%), high decreasing (7.9%), and moderate increasing class (8.2%). We conducted logistic regressions to investigate whether baseline levels and growth in cannabis use were associated with PLE trajectory membership. Then, we examined the effects of potential mediators (growth in cognition and anxiety/depression) on the relationship between growth in cannabis use and PLE trajectory. A steeper growth in cannabis use from 13- to 16-years was associated with a higher likelihood of being assigned to the moderate increasing trajectory of PLE [odds ratio, 2.59; 95% confidence interval (CI), 1.11-6.03], when controlling for cumulative cigarette use. Growth in depression symptoms, not anxiety or change in cognitive functioning, mediated the relationship between growth in cannabis use and the PLE moderate increasing group (indirect effect: 0.07; 95% CI, 0.03-0.11). Depression symptoms partially mediated the longitudinal link between cannabis use and PLE in adolescents, suggesting that there may be a preventative effect to be gained from targeting depression symptoms, in addition to attempting to prevent cannabis use in youth presenting increasing psychotic experiences. © 2017 Association for Child and Adolescent Mental Health.

Objective Studies have linked cognitive functioning to everyday social functioning in psychotic disorders, but the nature of the relationships between cognition, social cognition, symptoms, and social functioning remains unestablished. Modelling the contributions of non-social and social cognitive ability in the prediction of social functioning may help in more clearly defining therapeutic targets to improve functioning. Method In a sample of 745 patients with a non-affective psychotic disorder, the associations between cognition and social cognition at baseline on the one hand, and self-reported social functioning three years later on the other, were analysed. First, case-control comparisons were conducted; associations were subsequently further explored in patients, investigating the potential mediating role of symptoms. Analyses were repeated in a subsample of 233 patients with recent-onset psychosis. Results Information processing speed and immediate verbal memory were stronger associated with social functioning in patients than in healthy controls. Most cognition variables significantly predicted social functioning at follow-up, whereas social cognition was not associated with social functioning. Symptoms were robustly associated with follow-up social functioning, with negative symptoms fully mediating most associations between cognition and follow-up social functioning. Illness duration did not moderate the strength of the association between cognitive functioning and follow-up social functioning. No associations were found between (social) cognition and follow-up social functioning in patients with recent-onset psychosis. Conclusions Although cognitive functioning is associated with later social functioning in psychotic disorder, its role in explaining social functioning outcome above negative symptoms appears only modest. In recent-onset psychosis, cognition may have a negligible role in predicting later social functioning. Moreover, social cognition tasks

The velo-cardio-facial syndrome (VCFS) is caused by hemizygous deletions on chromosome 22q11.2. The VCFS phenotype is complex and characterized by frequent occurrence of neuropsychiatric symptoms with up to 25-30% of cases suffering from psychotic disorders compared with only ~1% in the general population (odds ratio≈20-25). This makes the 22q11.2 deletion one of the most prominent risk factors for schizophrenia. However, its penetrance for neuropsychiatric phenotypes is incomplete suggesting that additional risk factors are required for disease development. These additional risk factors could lie anywhere on the genome, but by reducing the normal diploid to a haploid state, the 22q11.2 deletion could result in the unmasking of otherwise recessive alleles or functional variants on the non-deleted 22q11.2 allele. To test this hypothesis, we captured and sequenced the whole 22q11.2 non-deleted region in 88 VCFS patients with (n=40) and without (n=48) psychotic disorders to identify genetic variation that could increase the risk for schizophrenia. Single nucleotide variants (SNVs), small insertions/deletions (indels) and copy number variants were called and their distributions were compared between the two diagnostic groups using variant-, gene- and region-based association tests. None of these tests resulted in statistical evidence for the existence of a genetic variation in the non-deleted allele that would increase schizophrenia risk in VCFS patients. Power analysis showed that our study was able to achieve >80% statistical power to detect association of a risk variant with an odd ratio of ⩾22. However, it is certainly under-powered to detect risk variant of smaller effect sizes. Our study did not provide evidence that genetic variants of very large effect size located on the non-deleted 22q1.2 allele in VCFS patients increase the risk for developing psychotic disorders. Variants with smaller effects may be located in the remaining 22q11.2 allele and elsewhere

Five-Factor Model (FFM) personality traits are related to a wide range of clinical outcome in patients with psychotic disorders. However, it is not sufficiently clear whether psychotic illness, particularly fluctuation in negative symptoms and psychotic relapse, affects personality. The current study examined the 3-year temporal stability of FFM traits in 91 patients with non-affective psychotic disorders with a maximum duration of illness of 10 years and 32 control subjects without a (family member with) a diagnosis of psychotic illness. In patients, change in negative symptoms predicted changes in Neuroticism and (inversely) in Extraversion and Openness. However, when correcting for depressive symptoms, negative symptoms no longer predicted change in any FFM trait. Clinical characteristics, such as psychotic relapse, were also not found to be related to change in FFM traits. Patients showed a slight increase in Conscientiousness levels, the other FFM traits showed mean-level stability. Rank-order stability of the FFM traits was moderate to strong, although weaker for Neuroticism in patients. Our findings indicate that psychotic symptoms exert limited effect on the stability of FFM traits in patients with psychotic disorders. Consistent with general population findings, one should guard against state-trait confusion between Neuroticism/Extraversion and depression. Copyright © 2015 Elsevier Ireland Ltd.

Prevent hospitalizations in psychotic disorders is an important aim, so long-acting antipsychotic is a good option that can control better the correct adherence. Moreover, in the current economic context pharmacoeconomic studies are necessary. We estimate the effect in prevention of paliperidone palmitate long-acting injection (PP-LAI) and calculate the economic cost in the 12 months preceding the start of treatment with PP-LAI and 12 months later. Mirror image study of 71 outpatients diagnosed with psychotic disorders and treated with PP-LAI. In a first analysis, we measured along one year: number of hospitalizations/year, number of hospitalization in days, number of emergency assists/year and if there is antipsychotics associated to long-acting treatment. After this phase, we applied Fees Act of Valencia for economic analysis and estimate of the cost per hospitalization (€ 5,640.41) and hospital emergency (€ 187.61). After one year of treatment with PP-LAI (mean dose=130.65mg/month), we obtained greater numbers in assistance variables: total hospitalizations decrease, 78.8% (P=.009); shortening in hospitalization days, 89.4% (P=.009); abridgement of number of emergency assists, 79.1% (P=.002); decrease of rate of antipsychotics associated to long-acting treatment, 21% (P<.0001); increase in monotherapy, 53.8% (P<.0001). Therefore, after 12 months of treatment with PP-LAI we obtained a reduction in inpatient spending (savings of € 175,766.54) and increased spending on antipsychotics 32% (equivalent to € 151,126.92). PP-LAI can be an effective therapy for the treatment of patients with severe psychotic disorders: improves symptomatic stability and can prevent hospitalizations with cost-effective symptom control.

Early social and cognitive alterations in psychotic disorder, associated with familial liability and environmental exposures, may contribute to lower than expected educational achievement. The aims of the present study were to investigate (1) how differences in educational level between parents and their children vary across patients, their healthy siblings, and healthy controls (effect familial liability), and across two environmental risk factors for psychotic disorder: childhood trauma and childhood urban exposure (effect environment) and (2) to what degree the association between familial liability and educational differential was moderated by the environmental exposures. Patients with a diagnosis of non-affective psychotic disorder (n = 629), 552 non-psychotic siblings and 326 healthy controls from the Netherlands and Belgium were studied. Participants reported their highest level of education and that of their parents. Childhood trauma was assessed with the Dutch version of the Childhood Trauma Questionnaire-Short Form. Urban exposure, expressed as population density, was rated across five levels. Overall, participants had a higher level of education than their parents. This difference was significantly reduced in the patient group, and the healthy siblings displayed intergenerational differences that were in between those of controls and patients. Higher levels of childhood urban exposure were also associated with a smaller intergenerational educational differential. There was no evidence for differential sensitivity to childhood trauma and childhood urbanicity across the three groups. Intergenerational difference in educational achievements is decreased in patients with psychotic disorder and to a lesser extent in siblings of patients with psychotic disorder, and across higher levels of childhood urban exposure. More research is required to better understand the dynamics between early social and cognitive alterations in those at risk in relation to progress

Telephone consultation and triage are used to limit the workload on emergency departments. Lack of visual cues and clinical tests put telephone consultations to a disadvantage compared to face-to-face consultations increasing the risk of under-triage. Under-triage occurs in telephone triage; however why under-triage happens is not explored yet. The aim of the study was to describe situations of under-triage in context, to assess the quality of under-triaged calls, and to identify communication patterns contributing to under-triage in a regional OOH service in the capital region of Denmark. Explanatory simultaneous mixed method with thematic analysis and descriptive statistics was chosen. The study was carried out in an Out-Of-Hours service (OOH) in the Capital Region of Denmark, Copenhagen. Under-triage was defined as Potentially Under-Triaged Calls (PUTC) by specific criteria to an OOH Hotline, and identification by integration of three databases: Medical Hotline database, Emergency number database, including the Ambulance database, and electronic patient records. Distribution of PUTC were carried out using ICD-10 codes to identify diagnosis and main themes identified by qualitative analysis of audio recorded under-triaged calls. Study period was October 15 th to November 30 th 2014. Three hundred twenty seven PUTC were identified, representing 0.04% of all calls (n = 937.056) to the OOH. Distribution of PUTC according to diagnoses was: digestive (24%), circulatory (19%), respiratory (15%) and all others (42%). Thematic analysis of the voice logs suggested that inadequate communication and non-normative symptom description contributed to under-triage. The incidence of potentially under-triage is low (0.04%). However, the over-representation of digestive, circulatory, and respiratory diagnoses might suggest that under-triage is related to inadequate symptom description. We recommend that caller and call-handler collaborate systematically on problem

The present study examined the impact of a brief version of an acceptance-based treatment (acceptance and commitment therapy; ACT) that teaches patients to accept unavoidable private events; to identify and focus on actions directed toward valued goals; and to defuse from odd cognition, just noticing thoughts rather than treating them as either true or false. Eighty inpatient participants with positive psychotic symptoms were randomly assigned to treatment as usual (TAU) or to 4 sessions of ACT plus TAU. ACT participants showed significantly higher symptom reporting and lower symptom believability and a rate of rehospitalization half that of TAU participants over a 4-month follow-up period. The same basic pattern of results was seen with all participant subgroups except delusional participants who denied symptoms.

The aim of this study was to investigate differences in subcortical and hippocampal volumes between healthy controls, young people at an early stage of affective and psychotic disorders and those in more advanced stages, to identify markers associated with functional outcomes and illness severity. Young people presenting to youth mental health services with admixtures of depressive, manic and psychotic symptoms (n = 141), and healthy counterparts (n = 49), aged 18-25 were recruited. Participants underwent magnetic resonance imaging, clinical assessments and were rated as to their current clinical stage. Eighty-four patients were classified at the attenuated syndrome stage (Stage 1b) and 57 were classified as having discrete and persistent disorders (Stage 2+). Automated segmentation was performed using NeuroQuant® to determine volumes of subcortical and hippocampus structures which were compared between groups and correlated with clinical and functional outcomes. Compared to healthy controls, Stage 2+ patients showed significantly reduced right amygdala volumes. Whereas Stage 1b patients showed significantly reduced left caudate volumes compared to healthy controls. Smaller left caudate volume correlated with greater psychological distress and impaired functioning. This study shows a clinical application for an automated program to identify and track subcortical changes evident in young people with emerging psychopathology. Crown Copyright © 2017.

Psychotic experiences, depressive and anxiety symptoms may be manifestations of a latent continuum of common mental distress. The Improving Access to Psychological Therapies (IAPT) programme has increased the reach of psychological treatments to people with common mental disorders in England. However, psychotic experiences are neither measured nor considered in therapy. We aimed to confirm the presence of psychotic experiences among IAPT service-users and determine whether these experiences are associated with higher depression/anxiety levels and poorer recovery. All service-users that attended the Fenland and Peterborough IAPT teams in Cambridgeshire between November 16, 2015 and January 29, 2016 participated in a service evaluation. In addition to routine mesures, such as the Generalized Anxiety Disorder-7 questionnaire (GAD-7) and the Patient Health Questionnaire-9 (PHQ-9), we introduced a shortened version of the Community Assessment of Psychic Experiences (CAPE-P15) to measure psychotic experiences. Classes of individuals were identified with latent class analysis. Associations were reported using Pearson correlation coefficient. One hundred and seventy-three services-users were included, mostly females (N = 133; 76.9%). The mean age was 36.6 (SD = 13.3). Around 30% likely belonged to a class with psychotic experiences. CAPE-P15 frequency was significantly correlated to PHQ-9 (r = 0.44; P < .001) and GAD-7 (r = 0.32; P < .001). Similarly, CAPE-P15 distress and both PHQ-9 (r = 0.43; P < .001) and GAD-7 (r = 0.38; P < .001) were highly correlated. These associations were replicated after the initial period of the therapy, indicating poor recovery. Some IAPT service-users suffer psychotic experiences. Tailoring available evidence-based psychological therapies for these people in IAPT settings might trailblaze a new care pathway to improve recovery in this group. © 2017 John Wiley & Sons Australia, Ltd.

Behavioural and psychiatric symptoms (BPS) are frequent in neurological patients, contribute to disability, and decrease quality of life. We recorded BPS prevalence and type, as well as any associations with specific diagnoses, brain regions, and treatments, in consecutive outpatients examined in a cognitive neurology clinic. A retrospective analysis of 843 consecutive patients was performed, including a review of BPS, diagnosis, sensory impairment, lesion topography (neuroimaging), and treatment. The total sample was considered, and the cognitive impairment (CI) group (n=607) was compared to the non-CI group. BPS was present in 59.9% of the patients (61.3% in the CI group, 56.4% in the non-CI group). One BPS was present in 31.1%, two in 17.4%, and three or more in 11.4%. BPS, especially depression and anxiety, are more frequent in women than in men. Psychotic and behavioural symptoms predominate in subjects aged 65 and older, and anxiety in those younger than 65. Psychotic symptoms appear more often in patients with sensory impairment. Psychotic and behavioural symptoms are more prevalent in patients with degenerative dementia; depression and anxiety in those who suffer a psychiatric disease or adverse effects of substances; emotional lability in individuals with a metabolic or hormonal disorder; hypochondria in those with a pain syndrome; and irritability in subjects with chronic hypoxia. Behavioural symptoms are more frequent in patients with anomalies in the frontal or right temporal or parietal lobes, and antipsychotics constitute the first line of treatment. Leaving standard treatments aside, associations were observed between dysthymia and opioid analgesics, betahistine and statins, and between psychotic symptoms and levodopa, piracetam, and vasodilators.

Persons with a psychotic disorder commonly experience difficulties with what is considered to be metacognitive capacity. In this article we discuss several definitions of this concept, the measurement instruments involved and the clinical interventions that target this concept. To present a review of various frequently used definitions of metacognition and related concepts and to describe the measurement instruments involved and the treatment options available for improving the metacognitive capacity of persons with a psychotic disorder. We present an overview of several definitions of metacognition in psychotic disorders and we discuss frequently used measurement instruments and treatment options. The article focuses on recent developments in a model devised by Semerari et al. The measurement instrument involved (Metacognition Assessment Scale - A) is discussed in terms of it being an addition to existing methods. On the basis of the literature it appears that metacognition and related concepts are measurable constructs, although definitions and instruments vary considerably. The new conceptualisation of social information processing also leads to the development of a new form of psychotherapy that aims to help patients suffering from psychotic disorders to improve metacognitive capacity. There seems to be evidence that metacognitive abilities are a possible target for treatment, but further research is needed.

Cognitive impairments have been extensively reported for patients suffering from schizophrenia but a lot of questions persist about these troubles. Several domains of cognitive functions are impaired which result in daily life difficulties. Many arguments tend to show that children suffering from psychotic spectrum disorders present cognitive impairments also but things are not clearly defined. The aim of this review is to compare the cognitive impairments of children suffering from psychotic symptoms and adults suffering from schizophrenia in order to improve the understanding of the two clinical affections. A better understanding of the disease is necessary to improve the health care which currently give poor results. Besides the Diagnostic and Statistical Manual (DSM-5) and the French reference books, the present research has been conducted using PubMed, Medline, PsycINFO, PsycARTICLES and ScienceDirect. Literature about cognitive impairments of adults with schizophrenia and children with psychotic spectrum disorders is assessed and results are compared. Both children and adults suffer from cognitive impairments: language, memories, executive and motor functions and IQ are impaired. An important heterogeneity in the troubles has been observed and a poor knowledge in terms of onset time, evolution, intensity, impact on everyday life and therapeutic interest has been reported. Adults with schizophrenia and children suffering from psychotic spectrum disorders have similar cognitive impairments in many domains of cognition. The similarities in term of cognitive impairments highlighted in the present work should support new studies in order to adapt to children the current cognitive therapies which are mostly provided to adults. As the cognitive impairments are heterogeneous, each patient should receive a tailored neurocognitive exam which takes into account its abilities and weaknesses.

Homeless persons with psychosis are particularly susceptible to unsheltered homelessness, which includes living on the streets, in cars, and other places not meant for human habitation. Homeless persons with psychosis have distinct barriers to accessing care and comprise a high-need and hard-to-serve homeless subpopulation. Therefore, this study sought to understand unsheltered homelessness in persons with psychosis and its relationship to cognitive impairment, clinical symptoms, and community functioning, examined both categorically and dimensionally. This study included 76 homeless participants with a history of a psychotic diagnosis who were enrolled in a supported housing program but had not yet received housing. This study used two different housing stability thresholds (literally homeless at any point vs. literally homeless >20% of days) for comparing homeless Veterans with psychosis living in sheltered versus unsheltered situations on cognition, clinical symptoms, and community integration. Dimensional analyses also examined the relationship between percentage of days spent in unsheltered locations and cognition, clinical symptoms, and community integration. Sheltered and unsheltered Veterans with psychosis did not differ on clinical symptoms or community integration, but there was an inconsistent group difference on cognition depending on the threshold used for determining housing stability. In the unsheltered group, cognitive deficits in overall cognition, visual learning, and social cognition were related to more days spent in unsheltered locations. Rehabilitation efforts targeting specific cognitive deficits may be useful to facilitate greater access to care and successful interventions in this population. Copyright © 2018 Elsevier B.V.

The aim was to examine the temporal relationships over 10 months between cannabis use and symptoms of psychosis and depression in people with schizophrenia and related disorders. The design was a prospective study of 101 patients with schizophrenia and related disorders who were assessed monthly over 10 months on medication compliance, cannabis and other drug use, symptoms of depression and symptoms of psychosis. Linear regression methods to assess relationships between cannabis use and symptoms of psychosis and depression while adjusting for serial dependence, medication compliance and other demographic and clinical variables. Cannabis use predicted a small but statistically significant increase in symptoms of psychosis, but not depression, after controlling for other differences between cannabis users and non-users. Symptoms of depression and psychosis did not predict cannabis use. Continued cannabis use by persons with schizophrenia predicts a small increase in psychotic symptom severity but not vice versa.

The cycloid psychoses have not been included in the modern classifications-what makes scientific research difficult. The aim of the present study is to investigate the presence and specific characteristics of the cycloid psychoses in a broad sample of first psychotic episodes. Seventy patients diagnosed with one-year first schizophrenia episode, schizophreniform disorder, or schizoaffective disorder were studied (mean age, 27.9 years old; SD±6.34). The detection of the possible cases of cycloid psychosis was done according to the Perris and Brockington operational criteria. Two groups of "cycloid" (n=11) and "non cycloid" (n=59) patients were compared according to demographic and clinical variables, and possible diagnostic variables were evaluated by the ROC curves. Significant differences were found between cycloid and non cycloid groups for a number of clinical variables: prodromic symptoms (pcycloid psychoses might represent differentiated and well-defined clinical entity.

Full Text Available Abstract Vitamin B12 is one of the essential vitamins affecting various systems of the body. Reports of psychiatric disorders due to its deficiency mostly focus on middle aged and elderly patients. Here we report a case of vitamin B 12 deficiency in a 16-year old, male adolescent who presented with mixed mood disorder symptoms with psychotic features. Chief complaints were “irritability, regressive behavior, apathy, crying and truancy” which lasted for a year. Premorbid personality was unremarkable with no substance use/exposure or infections. No stressors were present. The patient was not vegetarian. Past medical history and family history was normal. Neurological examination revealed glossitis, ataxia, rigidity in both shoulders, cog-wheel rigidity in the left elbow, bilateral problems of coordination in cerebellar examination, reduced swinging of the arms and masked face. Romberg’s sign was present. Laboratory evaluations were normal. Endoscopy and biopsy revealed atrophy of the gastric mucosa with Helicobacter Pylori colonization. Schilling test was suggestive of malabsorbtion. He was diagnosed with Mood disorder with Mixed, Psychotic Features due to Vitamin B12 Deficiency and risperidone 0.5 mg/day and intramuscular vitamin B12 500 mcg/day were started along with referral for treatment of Helicobacter pylori. A visit on the second week revealed no psychotic features. Romberg’s sign was negative and cerebellar tests were normal. Extrapyramidal symptoms were reduced while Vitamin B12 levels were elevated. Risperidone was stopped and parenteral Vitamin B12 treatment was continued with monthly injections for 3 months. Follow-up endoscopy and biopsy at the first month demonstrated eradication of H. pylori. He was followed monthly for another 6 months and psychiatric symptoms did not recur at the time of last evaluation. Despite limitations, this case may underline the observation that mood disorders with psychotic features

To study the characteristics of prolactin secretion in patients with a first psychotic episode (FPE) with regard to disease severity, gender and patient's neuromediator system state. Author studied 76 patients with schizophrenic spectrum disorders and 34 normals (control group). There was a significant negative sex-related correlation between the severity of psychopathologic symptoms and plasma prolactin levels. Based on the results author attempted to explain the hormonal disbalance in the patients with FPE taking into account the state of monoaminergic mediator systems in patients.

This study employed the Basic Personality Inventory (BPI) to differentiate various types of dis-simulation, including malingered psychopathology and faking good, by inmates. In particular, the role of intelligence in utilizing symptom information to successfully malinger was examined. On admission to a correctional facility, 161 inmates completed the BPI under standard instructions and then again under instructions to fake good (n = 55) or to malinger psychotic (n = 35), posttraumatic stress disorder (n = 36), or somatoform (n = 35) psychopathology. Unlike symptom information, intelligence evidenced some support for increasing inmates' effectiveness in malingering, although there was no relationship between higher intelligence and using symptom information to successfully evade detection. Overall, the BPI was more effective in detecting malingered psychopathology than faking good. Implications for the detection of dissimulation in correctional and forensic settings are discussed.

We present the case of a 35-year-old ranger who had no history of acute or chronic infectious disease or any previous neuropsychiatric symptoms. He arrived at the Psychiatry Clinic and was admitted as an emergency case, displaying bizarre behavior, hallucinations, paranoid ideation, and delusional faults. These symptoms had first appeared 7 days earlier. An objective examination revealed abnormalities of behavior, anxiety, visual hallucinations, choreiform, and tic-like facial movements. After the administration of neuroleptic and antidepressant treatment, he showed an initial improvement, but on day 10 entered into a severe catatonic state with signs of meningeal irritation and was transferred to the intensive care unit. An electroencephalogram showed diffuse irritative changes, raising the possibility of encephalitis. Taking into consideration the overt occupational risk, Borrelia antibody tests were prescribed and highly positive immunoglobulin (IgM and IgG titers were obtained from serum, along with IgG and antibody index positivity in cerebrospinal fluid.

Background Traumatic events are associated with increased risk of psychotic experiences, but it is unclear whether this association is explained by mental disorders prior to psychotic experience onset. Aims To investigate the associations between traumatic events and subsequent psychotic experience onset after adjusting for post-traumatic stress disorder and other mental disorders. Method We assessed 29 traumatic event types and psychotic experiences from the World Mental Health surveys and examined the associations of traumatic events with subsequent psychotic experience onset with and without adjustments for mental disorders. Results Respondents with any traumatic events had three times the odds of other respondents of subsequently developing psychotic experiences (OR = 3.1, 95% CI 2.7-3.7), with variability in strength of association across traumatic event types. These associations persisted after adjustment for mental disorders. Conclusions Exposure to traumatic events predicts subsequent onset of psychotic experiences even after adjusting for comorbid mental disorders. © The Royal College of Psychiatrists 2017.

Mental health problems account for almost half of all ill health in people under 65 years. The majority are non-psychotic (e.g. depression, anxiety and phobias). For some people, art therapy may provide more profound and long-lasting healing than more standard forms of treatment, perhaps because it can provide an alternative means of expression and release from trauma. As yet, no formal evaluation of art therapy for non-psychotic mental health disorders has been conducted. This review aimed to evaluate evidence for the clinical effectiveness and cost-effectiveness of art therapy for non-psychotic mental health disorders. Comprehensive literature searches for studies examining art therapy in populations with non-psychotic mental health disorders were performed in major health-related and social science bibliographic databases including MEDLINE, EMBASE, The Cochrane Library, Cumulative Index to Nursing and Allied Health Literature (CINAHL), PsycINFO, Allied and Complementary Medicine Database (AMED) and Applied Social Sciences Index and Abstracts (ASSIA) from inception up to May 2013. A quantitative systematic review of clinical effectiveness, a qualitative review to explore the acceptability, relative benefits and potential harms, and a cost-utility analysis of studies evaluating cost-effectiveness of art therapy were conducted. In the quantitative review, 15 randomised controlled trials (RCTs) were included (n = 777). Meta-analysis was not possible because of clinical heterogeneity and insufficient comparable data on outcome measures across studies. A narrative synthesis reports that art therapy was associated with significant positive changes relative to the control group in mental health symptoms in 10 out of the 15 studies. The control groups varied between studies but included wait-list/no treatment, attention placebo controls and psychological therapy comparators. Four studies reported improvement from baseline but no significant difference between groups

Both positive psychotic symptoms and anhedonia are associated with striatal functioning, but few studies have linked risk for psychotic disorders to a neural measure evoked during a striatal dopamine-related reward and punishment-based learning task, such as a reversal learning task (RLT; Cools et al, 2009). The feedback-related negativity (FRN) is a neural response that in part reflects striatal dopamine functioning. We recorded EEG during the RLT in three groups: (a) people with psychotic experiences (PE; n=20) at increased risk for psychotic disorders; (b) people with extremely elevated social anhedonia (SocAnh; n=22); and (c) controls (n=20). Behaviorally, consistent with increased striatal dopamine, the PE group exhibited better behavioral learning (ie, faster responses) after unexpected reward than after unexpected punishment. Moreover, although the control and SocAnh groups showed a larger FRN to punishment than reward, the PE group showed similar FRNs to punishment and reward, with a numerically larger FRN to reward than punishment (with similar results on these trials also found for a P3a component). These results are among the first to link a neural response evoked by a reward and punishment-based learning task specifically with elevated psychosis risk.

Full Text Available The aim of this study was to evaluate the usage prevalence of herbal products (HP and to ascertain the identity, mode and adverse effects of plant taxa used in self-medication practice for anxiety, depression and insomnia in patients with non-psychotic disorders originating from southeastern Serbia. Also, we compared HP users and non-users on the variables of socio-demographic characteristics, information source and origin of HP. The study was done by a face-to-face interview with a trained psychiatrist using a structured questionnaire administered to 136 adult patients suffering from non-psychotic mental disorders. A typical herbal-product user among non-psychotic psychiatric patients from southeastern Serbia is a middle-aged married woman, with a secondary level of education, unemployed and living in an urban area. Non-psychotic psychiatric patients, although not living predominantly in rural areas, were familiar with a variety of ethno-medicines and were often using HP primarily without the consultation of their psychiatrists/physicians. HP stated to be most frequently used for psychiatry-related symptoms included: Melissa officinalis, Mentha × piperita, Hypericum perforatum and Valeriana officinalis. The interviewees rarely stated adverse reactions related to the HP usage; however, this should not be generalized, since HP are known to vary in the content of their adverse reaction-causing constituents.

Caffeine is a widely used psychoactive substance that has the potential to contribute to many psychiatric symptoms. This review article aims to address the specific research studies and case reports that relate caffeine to psychiatric symptoms. Caffeine can cause anxiety symptoms in normal individuals, especially in vulnerable patients, like those with pre-existing anxiety disorders. Caffeine use is also associated with symptoms of depression due to either a self-medication theory, or a theory that caffeine itself causes changes in mood. Psychosis can be induced in normal individuals ingesting caffeine at toxic doses, and psychotic symptoms can also be worsened in schizophrenic patients using caffeine. Sleep and symptoms of ADHD may be altered by caffeine as well. Prevention of caffeine-induced psychiatric symptoms is possible by recognizing, educating, and treating patients using a tapering approach.

Full Text Available We sought to characterize the relationship between integrity of the white matter underlying the ventral anterior cingulate (vAC and depressive symptoms in older adults with atherosclerotic vascular disease (AVD, a condition associated with preferential degeneration of the white matter. The ventral anterior cingulate was defined as including white matter underlying ventral Brodmann Area 24 and Brodmann Area 25, corresponding with the subcallosal and subgenual cingulate respectively. This region of interest was chosen based on the preponderance of evidence that the white matter in the region plays a critical role in the manifestation of depressive symptoms. Participants had current unequivocal diagnoses of AVD and were between 55 and 90 years old. Fractional anisotropy (FA was used as an index of white matter integrity and organization. Whole-brain mean diffusivity (MD was used as an index of global white matter lesion burden. Depressive symptoms were measured using the Symptom Checklist-90-Revised (SCL-90-R Depression Scale. Depressive symptoms were significantly related to low FA in the right vAC (r=-.356, DF=30, p=.045 but not the left vAC (r=.024, DF=30, p=.896 after controlling for total brain MD (a statistical control for global white matter lesion burden. Further, depressive symptoms were significantly related to low FA in the right vAC (r=-0.361, DF=31, p=.039, but not the left vAC (r=.259, DF=31, p=.145 when controlled for the contralateral vAC FA. The correlation coefficients for this follow-up analysis were found to be significantly different between left and right vAC (Z=2.310, p=.021.Poor white matter health in the vAC may be a biological mechanism for depressive symptoms in older adults with vascular disease. Further studies may corroborate that the right vAC plays a unique role in depressive symptom manifestation in cases where the white matter is preferentially affected, as is the case in AVD. This could lead to future targeting of

Successful social interaction requires the ability to integrate as well as distinguish own and others' actions. Normally, the integration and distinction of self and other are a well-balanced process, occurring without much effort or conscious attention. However, not everyone is blessed with the ability to balance self-other distinction and integration, resulting in personal distress in reaction to other people's emotions or even a loss of self [e.g., in (subclinical) psychosis]. Previous research has demonstrated that the integration and distinction of others' actions cause interference with one's own action performance (commonly assessed with a social Simon task). The present study had two goals. First, as previous studies on the social Simon effect employed relatively small samples (N action interference effect. Second, we tested to what extent action interference reflects individual differences in traits related to self-other distinction (i.e., personal distress in reaction to other people's emotions and subclinical psychotic symptoms). Based on a questionnaire study among a large sample (N = 745), we selected a subsample (N = 130) of participants scoring low, average, or high on subclinical psychotic symptoms, or on personal distress. The selected participants performed a social Simon task. Results showed a robust social Simon effect, regardless of individual differences in personal distress or subclinical psychotic symptoms. However, exploratory analyses revealed that the sex composition of interaction pairs modulated social Simon effects. Possible explanations for these findings are discussed.

Depressive and anxiety disorders are often first diagnosed during adolescence and it is known that they persist into adulthood. Previous studies often tried to dissociate depressive and anxiety disorders, but high comorbidity makes this difficult and maybe even impossible. The goal of this study was to use neuroimaging to test what the unique contribution is of depression and anxiety symptomatology on emotional processing and amygdala activation, and to compare the results with a healthy control group. We included 25 adolescents with depressive and/or anxiety disorders and 26 healthy adolescents. Participants performed an emotional face processing task while in the MRI scanner. We were particularly interested in the relation between depression/anxiety symptomatology and patterns of amygdala activation. There were no significant differences in activation patterns between the control group and the clinical group on whole brain level and ROI level. However, we found that dimensional scores on an anxiety but not a depression subscale significantly predicted brain activation in the right amygdala when processing fearful, happy and neutral faces. These results suggest that anxiety symptoms are a better predictor for differentiating activation patterns in the amygdala than depression symptoms. Although the current study includes a relatively large sample of treatment naïve adolescents with depression/anxiety disorders, results might be influenced by differences between studies in recruitment strategies or methodology. Future research should include larger samples with a more equal distribution of adolescents with a clinical diagnosis of depression and/or anxiety. To conclude, this study shows that abnormal amygdala responses to emotional faces in depression and anxiety seems to be more dependent on anxiety symptoms than on depression symptoms, and thereby highlights the need for more research to better characterize clinical groups in future studies.

Stigmatisation is a source of chronic stress and a major barrier to recovery for people with mental illnesses. The internalisation of stigma can have a negative impact on an individual's social relations and lead to feelings of loneliness and depression. This research is aimed at testing the hypothesis that the internalised stigma of mental illness contributes to the intensification of depressive symptoms indirectly, through its impact on feelings of loneliness. A total of 110 individuals with diagnoses of psychotic disorders (International Classification of Diseases-10th Revision (ICD-10): F20-F29) were assessed with measures of internalised stigma, loneliness, depression, positive and negative symptoms and global functioning. The ordinary least squares regression was used for data analysis. After adding loneliness to the regression model, the initially significant impact of internalised stigma on depressive symptoms disappeared. As expected, loneliness proved to be a full mediator in the relationship between stigma and depression. The study findings provide useful insights into the mechanisms of the harmful effects of stigma on people with mental illness. Internalised stigma and loneliness should be considered important targets for interventions aiming to promote recovery. © The Author(s) 2013.

The recovery movement differentiated clinical, which is related to disorder's symptoms, from personal recovery, which is outlined by a subjectively defined wellness state, characterised by hope and self-management. Schizophrenia research has long focused on risk factors and symptoms. The recovery movement triggered a focus shift from psychopathology towards better adjustment and growth despite living with schizophrenia. The recovery movement flourished parallel with positive psychology, the scientific study of ordinary human strengths and virtues investigating human motives and potentials. Understanding of human strengths could contribute to prevention or lessening of psychiatric disorders' devastating consequences, since optimism, sense of personal control and many other positive processes promote psychological health. Lately, the concepts of positive psychology have been implemented in schizophrenia research. Positive self-appraisals moderated suicidal ideation, even when patients experienced high levels of hopelessness.1 Additionally, among other factors, better self-images, internal locus of control (i.e. the perception that events in one's life relate to one's actions) and emphasis on personal efforts predicted a more favourable outcome in functioning of unmedicated patients.2 The concept of "resilience" is closely related to positive psychology. The American Psychological Association defines resilience as ''the process of adapting well in the face of adversity, trauma, threats or significant sources of stress''. The concept of resilience includes rebound from adversity.3 Determinants of resilience include biological, psychological, social and cultural factors that interact in a complex manner. The major manifestations of personal resilience are social competence, problem solving, autonomy and sense of purpose.5 Personality strengths that relate to resilience include high self-esteem, extroversion and optimism. Internal assets and personal competencies

BACKGROUND: Alterations in Theory-of-Mind (ToM) are associated with psychotic disorder. In addition, studies in children have documented that alterations in ToM are associated with Psychotic Experiences (PE). Our aim was to examine associations between an exaggerated type of ToM (HyperToM) and PE...... in children. Children with this type of alteration in ToM infer mental states when none are obviously suggested, and predict behaviour on the basis of these erroneous beliefs. Individuals with HyperToM do not appear to have a conceptual deficit (i.e. lack of representational abilities), but rather they apply......-control sampling frame of children with auditory verbal hallucinations. Multinomial regression analyses were carried out to investigate the associations between PE and ToM and HyperToM respectively. Analyses were adjusted for gender and proxy measures of general intelligence. RESULTS: Low ToM score...

The examination of potential roles of epigenetic alterations in the pathogenesis of psychotic diseases have become an essential alternative in recent years as genetic studies alone are yet to uncover major gene(s) for psychosis. Here, we describe the current state of knowledge from the gene-specific and genome-wide studies of postmortem brain and blood cells indicating that aberrant DNA methylation, histone modifications and dysregulation of micro-RNAs are linked to the pathogenesis of mental diseases. There is also strong evidence supporting that all classes of psychiatric drugs modulate diverse features of the epigenome. While comprehensive environmental and genetic/epigenetic studies are uncovering the origins, and the key genes/pathways affected in psychotic diseases, characterizing the epigenetic effects of psychiatric drugs may help to design novel therapies in psychiatry.

Male genital self-mutilation (GSM) is a rare, but serious phenomenon. Some of the risk factors for this act are: presence of religious delusions, command hallucinations, low self-esteem and feelings of guilt associated with sexual offences. Other risk factors include failures in the male role, problems in the early developmental period, such as experiencing difficulties in male identification and persistence of incestuous desires, depression and having a history of GSM. The eponym Klingsor Syndrome, which involves the presence of religious delusions, is proposed for GSM. Four male GSM cases are presented: Case 1 and Case 2 were diagnosed with schizophrenia, Case 3 with schizophrenia and depressive disorder, not otherwise specified, and Case 4 with bipolar depression with psychotic features. All definite and probable motives and cultural aspects for their GSM are discussed. Atonement is proposed as a new concept in formulating religiously themed psychotic male GSM.

Long-term care systems may alleviate caregiver burdens, particularly for those with fewer resources. However, it remains unclear whether socioeconomic disparity in caregiver burdens exists under a public, universal long-term care insurance (LTCI) system. This study examined income-based inequalities in caregiving time and depressive symptoms in Japanese older family caregivers. We further compared inequality in depressive symptoms with that of non-caregivers to evaluate whether family caregiving exacerbates this disparity. Data were obtained from a cross-sectional, nationwide survey conducted by the Japan Gerontological Evaluation Study in 2013. Participants were functionally independent older adults aged ≥65 years (N = 21,584). Depressive symptoms were assessed using the Geriatrics Depression Scale (GDS); caregiving hours per week, household income, and other covariates were also assessed. Family caregivers occupied 8.3% of the total. A Poisson regression model revealed that caregivers in lower income groups (compared to those in the highest) were 1.32 to 1.95 and 1.63 to 2.68 times more likely to engage in ≥36 and ≥72 hours/week of caregiving, respectively. As for the GDS (≥5), an excess risk was found in the caregivers in lower (compared to higher) income groups (adjusted prevalence ratio: 1.57-3.10). However, an interaction effect of income by caregiving role indicated no significant difference in inequality between caregivers and non-caregivers (p = .603). The excess risk for GDS (≥5) in the caregivers compared to non-caregivers was observed across income groups. Our findings revealed a possible disparity in family caregivers under the public LTCI system. Further studies should examine factors associated with longer caregiving hours in lower income households. Our findings also suggest the necessity for more efforts to alleviate depressive symptoms in family caregivers under the LTCI system regardless of income level, rather than exclusively

Bipolar disorder is a severe chronic mental illness that affects a large number of individuals. This disorder is separated into two major types, bipolar I disorder, with mania and typically recurrent depression, and bipolar II disorder, with recurrent major depression and hypomania. Patients with bipolar disorder spend the majority of time experiencing depression, and this typically is the presenting symptom. Because outcomes are improved with earlier diagnosis and treatment, physicians should maintain a high index of suspicion for bipolar disorder. The most effective long-term treatments are lithium and valproic acid, although other drugs also are used. In addition to referral to a mental health subspecialist for initiation and management of drug treatment, patients with bipolar disorder should be provided with resources for psychotherapy. Several comorbidities commonly associated with bipolar disorder include other mental disorders, substance use disorders, migraine headaches, chronic pain, stroke, metabolic syndrome, and cardiovascular disease. Family physicians who care for patients with bipolar disorder should focus their efforts on prevention and management of comorbidities. These patients should be assessed continually for risk of suicide because they are at high risk and their suicide attempts tend to be successful.

The overall aim of this thesis was to identify possible demographical, clinical, and neurocognitive risk factors for suicidal behaviour in patients with psychotic disorders. Suicidal behaviour and neurocognitive impairment are serious and prevalent problems in patients with schizophrenia. Studies indicate that suicidality in patients with schizophrenia may be associated with relatively higher neurocognitive functioning, but the findings are few and inconsistent.

In this contribution, which takes account of important findings in neuroscientific as well as psychoanalytic research, the authors explore the meaning of the deep-going distortions of psychic functioning occurring in hallucinatory phenomena. Neuroscientific studies have established that hallucinations distort the sense of reality owing to a complex alteration in the balance between top-down and bottom-up brain circuits. The present authors postulate that hallucinatory phenomena represent the outcome of a psychotic's distorted use of the mind over an extended period of time. In the hallucinatory state the psychotic part of the personality uses the mind to generate auto-induced sensations and to achieve a particular sort of regressive pleasure. In these cases, therefore, the mind is not used as an organ of knowledge or as an instrument for fostering relationships with others. The hallucinating psychotic decathects psychic (relational) reality and withdraws into a personal, bodily, and sensory space of his own. The opposing realities are not only external and internal but also psychic and sensory. Visual hallucinations could thus be said to originate from seeing with the 'eyes' of the mind, and auditory hallucinations from hearing with the mind's 'ears'. In these conditions, mental functioning is restricted, cutting out the more mature functions, which are thus no longer able to assign real meaning to the surrounding world and to the subject's psychic experience. The findings of the neurosciences facilitate understanding of how, in the psychotic hallucinatory process, the mind can modify the working of a somatic organ such as the brain.

The relevance of negative symptoms across the diagnostic spectrum of the psychoses remains uncertain. The purpose of this study was to report on prevalence of item and subscale level negative symptoms across the first episode psychosis (FEP) diagnostic spectrum in an epidemiological sample, and to ascertain whether items and subscales were more prevalent in a schizophrenia spectrum diagnoses group compared to an \\'all other psychotic diagnoses\\' group. We measured negative symptoms in 330 patients presenting with FEP using the Scale for Assessment of Negative Symptoms (SANS), and ascertained diagnosis using the Structured Clinical Interview for DSM IV. Prevalence of SANS items and subscales were tabulated across all psychotic diagnoses, and logistic regression analysis determined which items and subscales were predictive of schizophrenia spectrum diagnoses. SANS items were most prevalent in schizophrenia spectrum conditions but frequently presented in other FEP diagnoses, particularly substance induced psychotic disorder and Major Depressive Disorder. Brief psychotic disorder and bipolar disorders had low levels of negative symptoms. SANS items and subscales which significantly predicted schizophrenia spectrum diagnoses, were also frequently present in some of the other psychotic diagnoses. Conclusions: SANS items have high prevalence in FEP, and while commonest in schizophrenia spectrum conditions are not restricted to this diagnostic subgroup.

There is evidence that social support predicts self-esteem and related moods for people with psychotic disorders. However, there has been little investigation of relative importance of specific components of social support. Evidence from social psychology suggests that perceived relational evaluation (PRE) or the extent to which people see others as valuing them, is a particularly important determinant of self-esteem and mood. Our study compared the importance of PRE and other types of social support, in predicting self-esteem and depressive mood, anxiety, and anger-hostility in a sample of patients in an early intervention program for psychotic disorders. One hundred and two patients of the Prevention and Early Intervention Program for Psychoses in London, Ontario, completed measures of PRE, appraisal, tangible and general emotional social support, self-esteem, and mood. In addition, ratings of positive and negative symptoms were completed for all participants. In general, perceived relational value was the most important predictor of self-esteem and mood. These relations were not a result of confounding with positive or negative symptoms. PRE appears to be a particularly important aspect of social support in predicting self-esteem and mood states. Possible implications of these findings and future research directions are discussed.

Improving diagnostic batteries to identify individuals at-risk for developing psychotic disorders as early as possible is an ongoing challenge in schizophrenia research. Here, we sought to explore whether metacognition in at-risk of developing psychosis would differ from that of first episode psychosis and unaffected controls and whether dysfunctional metacognitive beliefs would be associated with psychosocial functioning in the clinical groups. Twenty-three subjects at-risk of psychosis were compared with a group of 15 first psychotic episode patients and 21 healthy controls with regard to their metacognitive beliefs and psychosocial functioning. Metacognition was assessed using the Metacognition Questionnaire (MCQ), psychosocial functioning was rated using the Personal and Social Performance Scale (PSP). Depression and anxiety were also evaluated. The clinical groups differed significantly from controls in several MCQ scores, particularly the subscales "negative beliefs" and "need for control," as well as on all PSP scales. Furthermore, significant correlations emerged between the metacognition and psychosocial functioning. A mediation analysis revealed that dysfunctional metacognitive beliefs had no direct effect on psychosocial functioning, but was mediated by depressive symptoms. These results corroborate findings assigning depressive symptoms an important role in early recognition of psychosis. © 2018 John Wiley & Sons Australia, Ltd.

This study identified risk factors for homelessness among indigent urban adults without dependent children and with no history of psychotic illness. We conducted a matched case-control study, stratified by sex, of 200 newly homeless men and women and 200 indigent men and women with no history of homelessness. Newly homeless case subjects were recruited from shelter assessment centers in New York City. Never-homeless control subjects, selected from public assistance centers, were single adults applying for home relief. Control subjects were matched with case subjects according to ethnicity, age, and sex. Trained interviewers employed standardized research instruments to probe 3 domains of risk factors: symptom severity and substance use disorder, family support and functioning, and prior use of services. Significant interaction effects by sex were present for symptom severity, heroin use disorder, and prior service use. Greater numbers of the homeless of both sexes lacked a high school diploma and had less income from all sources, including from their families, than of the never homeless. Newly homeless men and women with no history of psychotic illness differed from their never-homeless counterparts in the 3 domains investigated, but socioeconomic factors were also important.

In this article the formation of psychopathological predictors auto-aggressive behavior in patients with a first psychotic episode were identified, which became "targets" in the framework of a comprehensive emergency suicide assistance to conduct the crisis psychotherapy. The work was done on the basis of the Sumy regional psychoneurologic dispensary, where 100 patients with a first psychotic episode were examined: 52 of them (core group) had suicidal symptoms and 48 (control group) had not. According to the test results of severity of auto-aggressive predictors (pre-suicidal syndrome) to clinicopsychopathological predictors of auto-aggressive behavior include: the narrowing of the cognitive function (p≤0,001), the avoidance of interpersonal contact (r≤0,001), the presence of affective (p≤0,001) and vegetative (p≤0,01) violations, the autoaggression of moderate severity (p≤0,001) and impulsivity (p≤0,001). Patients of the core group with the auto-aggressive behavior (n=58) completed a course of a crisis psychotherapy comprising the stages of crisis support, crisis intervention and increase the adaptation layer. After a psychotherapy course levels of aggression (6,45±0,41), auto-aggression (of 9,68±0,67), disorders in the affective sphere (18,58±0,66) and impulsivity (of 4,23±0,30) decreased, which was manifested in increasing tolerance to emotional stress factors, control over their emotions and reduce their affective valence (p≤0,001). The expansion of interpersonal interaction, the increase of patients social activity, the blood relationships establishment (of 9,23±0,40) was observed.

Collaborative research projects have the potential to answer important research questions, which may otherwise require huge resources, funding, and time to complete. There are several scales for measuring psychotic symptoms in schizophrenia and other psychotic disorders, with the Scale for Assessment of Positive Symptoms (SAPS), Scale for Assessment of Negative Symptoms (SANS), Positive and Negative Symptom Scale (PANSS), and the Brief Psychiatric Rating Scale (BPRS) being among the most commonly used. High quality research efforts have used these three scales in different projects, and in order to merge study efforts, some means of combining data from these scales may be necessary. We reviewed correlations in published studies for these three scales, finding them to be highly correlated, however on comparison of the three scales there were considerable clinical differences between them. The paper discusses potential methods for combining the scales in collaborative research, including use of the recently developed standardised remission criteria for schizophrenia.

A study was performed to acquire urine, serum and oral fluid samples in cases of suspected driving under the influence of drugs of abuse. Oral fluid was collected using a novel sampling/testing device (Dräger DrugTest System). The aim of the study was to evaluate oral fluid and urine as a predictor of blood samples positive for drugs and impairment symptoms. Analysis for cannabinoids, amphetamine and its derivatives, opiates and cocaine was performed in urine using the Mahsan Kombi/DOA4-test, in serum using immunoassay and gas chromatography-mass spectrometry (GC-MS) confirmation and in oral fluid by GC-MS. Police and medical officer observations of impairment symptoms were rated and evaluated using a threshold value for the classification of driving inability. Accuracy in correlating drug detection in oral fluid and serum were >90% for all substances and also >90% in urine and serum except for THC (71.0%). Of the cases with oral fluid positive for any drug 97.1% of corresponding serum samples were also positive for at least one drug; of drug-positive urine samples this were only 82.4%. In 119 of 146 cases, impairment symptoms above threshold were observed (81.5%). Of the cases with drugs detected in serum, 19.1% appeared not impaired which were the same with drug-positive oral fluid while more persons with drug-positive urine samples appeared uninfluenced (32.7%). The data demonstrate that oral fluid is superior to urine in correlating with serum analytical data and impairment symptoms of drivers under the influence of drugs of abuse.

Full Text Available Abstract Background Psychotic depression is a clinical subtype of major depressive disorder. A number of clinical studies have demonstrated the efficacy of the combination of an antidepressant (for example, a tricyclic antidepressant or selective serotonin reuptake inhibitor (SSRI and an atypical antipsychotic or electroconvulsive therapy in treating psychotic depression. In some cases, the clinician or patient may prefer to avoid antipsychotic drugs altogether because of the risk of extrapyramidal side effects (EPS in patients with psychotic depression treated with these drugs. Methods We report five cases where fluvoxamine monotherapy was effective in the patients with psychotic depression. Results The scores on the Hamilton Depression (HAM-D scale and the Brief Psychiatric Rating Scale (BPRS in the five patients with psychotic depression were reduced after fluvoxamine monotherapy. Conclusion Doctors should consider fluvoxamine monotherapy as an alternative approach in treating psychotic depression because it avoids the risk of EPS from antipsychotic drugs.

Dysphagia can be due to a variety of causes in a psychotic patient. It could be a side-effect of anti-psychotic medication or the manifestation of a psychotic phenomenon or even due to a co-morbid medical cause. We report a case of dysphagia in a young lady with psychosis who had been recently started on anti-psychotic medication. We would specifically like to highlight the practical challenges regarding its diagnosis and report success with a systematic management approach. PMID:23226858

Not all individuals who smoke cannabis report psychotic-like experiences. Given that risk factors for psychotic disorders are multifaceted, precipitating factors to psychotic-like experiences after cannabis are likely to be equally complex. Reduced neurocognitive performance is associated with both psychosis risk and cannabis use. Therefore, it is possible cognitive performance may differentiate those who report psychotic-like experiences after cannabis from those who do not. We determined whether those reporting psychotic/dysphoric experiences after cannabis had reduced neurocognitive performance compared to those reporting primarily euphoric experiences. Participants were recruited on the basis of responses to the cannabis high captured by the Psychosis-Dysphoric and Euphoric experiences subscales from the Cannabis Experiences Questionnaire (CEQ). Compared to participants reporting primarily euphoric cannabis experiences (n = 36; 44% male; mean age (SD) = 28 (9) years), those who reported psychotic/dysphoric experiences (n = 40; 45% male; mean age (SD) = 26 (5) years) demonstrated significantly faster responses to a trial and error learning task. In the presence of distracters, those with psychotic/dysphoric experiences after cannabis made more errors on a Continuous Performance Task. Those who report psychotic/dysphoric experiences after cannabis have subtle inefficiencies in their cognitive processes. The multiple factors which predict vulnerability to psychotic-like experiences after cannabis require further investigation. Copyright © 2016 John Wiley & Sons, Ltd.

Disturbances of mentalization have been increasingly associated with the symptoms and functional impairment of people with psychotic disorders. it has been proposed that psychotherapy designed to foster self and other understanding, such as mentalization-based treatment (mBt), may play an important part in facilitating recovery from psychosis. Here, we present an attachment-based understanding of mentalization impairments. We then outline a neuropsychological model that links disruptions of mentalization associated with disturbances in the caregiving environment to the pathophysiology of psychosis in genetically at-risk individuals. this is followed by an illustration of some of the core mBt techniques for the rehabilitation of the capacity to mentalize as applied to the treatment of a patient with a psychotic disorder.

Studies have suggested that psychotic-like experiences (PLEs) are associated with behavioral problems in adolescents. The aim of this study was to investigate relationships between domains of PLEs, suicidal ideation, and depression in a large community sample of adolescents. The sample consisted of 8096 Korean subjects (3184 boys and 4912 girls) aged 14 to 19 years. The level of PLEs, depression, and suicidal ideation were assessed by the Eppendorf schizophrenia inventory (ESI), Beck's depression inventory, and Beck's scale for suicidal ideation, respectively. Both the level of depression and suicidal ideation were significantly associated with PLEs. Among the four domains of the ESI, the deviant perception, ideas of reference, and auditory uncertainty were associated with the suicidal ideation. Additionally, subjects with more PLEs had significantly more suicidal ideation and depressive symptoms. PLEs in adolescents are associated with potential risk of suicide and depressive symptoms significantly mediated the association between suicidal ideation and PLEs. The presence of perceptual disturbances, ideas of reference, and depression may be regarded as warning signs for suicide-related behaviors. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

Past studies using the Bonn Scale for the Assessment of Basic Symptoms (hereafter, Bonn Scale) have shown that self-reported perceptual/cognitive disturbances reveal which persons have or will soon develop schizophrenia. Here, we focused specifically on the clinical value of self-reported visual perceptual abnormalities (VPAs) since they are underexplored and have been associated with suicidal ideation, negative symptoms, and objective visual dysfunction. Using the 17 Bonn Scale vision items, we cross-sectionally investigated lifetime occurrence of VPAs in 21 first-episode psychosis and 22 chronic schizophrenia/schizoaffective disorder (SZ/SA) patients. Relationships were probed between VPAs and illness duration, symptom severity, current functioning, premorbid functioning, diagnosis, and age of onset. Increased VPAs were associated with: earlier age of onset; more delusions, hallucinations, bizarre behavior, and depressive symptoms; and worse premorbid social functioning, especially in the childhood and early adolescent phases. SZ/SA participants endorsed more VPAs as compared to those with schizophreniform or psychotic disorder-NOS, especially in the perception of color, bodies, faces, object movement, and double/reversed vision. The range of self-reported VPAs was strikingly similar between first-episode and chronic patients and did not depend on the type or amount of antipsychotic medication. As a comparative benchmark, lifetime occurrence of visual hallucinations did not depend on diagnosis and was linked only to poor premorbid social functioning. A brief 17-item interview derived from the Bonn Scale is strongly associated with core clinical features in schizophrenia. VPAs hold promise for clarifying diagnosis, predicting outcome, and guiding neurocognitive investigations.

Having sufficient sera concentrations of 25-hydroxyvitamin D is important for a range of health outcomes including cardiometabolic diseases. Clinical studies in people with psychotic disorders suggest that a sizable proportion has suboptimal vitamin D status (i.e. vitamin D deficiency or insufficiency). Individuals with psychosis also have many of the risk factors associated with suboptimal vitamin D status such as smoking, obesity, and reduced physical activity. The aim of this study was to examine the prevalence and socio-demographic and clinical correlates of vitamin D status using a large, population-based sample of adults with psychotic disorders. Data were collected as part of the Survey of High Impact Psychosis, a population-based survey of Australians aged 18-64 years with a psychotic disorder. 25-Hydroxyvitamin D concentration was measured in 463 participants. 25-Hydroxyvitamin D concentration was dichotomised into optimal (above 50 nmol/L) and suboptimal (below 50 nmol/L). The influence of a range of socio-demographic and clinical variables on vitamin D status was examined using logistic regression. Nearly half (43.6%) of the participants had suboptimal vitamin D status. Those with (a) increased physical activity or (b) positive symptoms had significantly reduced odds of having suboptimal vitamin D status. However, there were no significant associations between suboptimal vitamin D status and other psychiatric symptom measures or cardiometabolic risk factors. Many people with psychotic disorders have suboptimal vitamin D status. As part of the routine assessment of physical health status, clinicians should remain mindful of vitamin D status in this vulnerable population and encourage the use of appropriate vitamin D supplements.
Full Text Available Background: Breast cancer is the most common malignancy among women worldwide. In Iran, breast cancer ranks first among cancers diagnosed in women. Nevertheless, many of women haven’t enough knowledge about breast cancer risk factors and symptoms. The main reason for this escalating mortality is lack of awareness and late diagnosis of disease. The aim of present study assessed the knowledge about risk factors and symptoms of breast cancer, also the screening method and practice (Breast self examination about it. Methods: This is a descriptive and cross-sectional study. In this study 340 red crescent volunteer women participated in a national congress were selected with convenience sampling method. The data collection instrument consisted of a three part questionnaire which included demographic factors, Knowledge level about risk factors, symptoms and screening methods of breast cancer and questions concerning practice about breast self examination (BSE.The study tool was a researcher-designed questionnaire which could evaluated a number of variables. After data collection, analysis was carried out with descriptive tests by SPSS.16 software. Results: The mean age of subjects was 23±2.1yrs. Knowledge about breast cancer risk factors was very poor, the most widely known risk factor and lowest among the participants was family history of breast cancer (30.6 % and early menarche (under 12 years (0.3% respectively. Only 47.9% respondents correctly recognized breast lump and 11.2% breast discharge as the most common symptoms of breast cancer.30% of subjects were aware of BSE. However, a lesser proportion (9.4% was done BSE regular monthly every few months. Conclusion: Regarding the low level of the women’s knowledge about breast cancer especially in young educated women, screening and interventional programs to improve awareness and practice is essential.

Approximately half of psychostimulant users experience psychotic symptoms, which include both positive and negative symptoms. Prior reports have exclusively used positive symptoms to characterize psychostimulant associated psychosis. Symptoms vary dramatically in severity, though most investigations categorize psychosis as a dichotomous occurrence. To explore the association between different substances of abuse and the severity of psychotic symptoms, we investigated 171 individuals meeting DSM-IV-TR criteria for psychostimulant (cocaine or methamphetamine) dependence in an observational cross-sectional study. Participants were predominantly male (72.5%), recruited from a socially disadvantaged neighborhood in Vancouver, Canada, with a mean age of 45.5(±8.8) years. Of the total sample, 85% were dependent on cocaine, and 28.1% were dependent on methamphetamine. Participants had a median total PANSS score of 63, ranging from 37 to 111. Demographic information, current substance use and early substance exposure were used to predict positive and negative psychotic symptom severity in linear regression models. Increased severity of positive psychotic symptoms was significantly related to greater methamphetamine and marijuana use in the past 28 days, and methadone-abstinence. Negative symptom severity was related to increased opioid use in the past 28 days. There was no overlap between predictors of positive and negative symptom severity.

Abstract Relative to the general population, individuals with psychotic disorders have a higher risk of suicide. Suicide risk is also elevated in criminal offenders. Thus, psychotic-disordered individuals with antisocial tendencies may form an especially high-risk group. We built upon prior risk analyses by examining whether neurobehavioral correlates of social cognition were associated with suicidal behavior in criminal offenders with psychotic disorders. We assessed empathic accuracy and brain structure in four groups: (i) incarcerated offenders with psychotic disorders and past suicide attempts, (ii) incarcerated offenders with psychotic disorders and no suicide attempts, (iii) incarcerated offenders without psychotic disorders and (iv) community non-offenders without psychotic disorders. Established suicide risk variables were examined along with empathic accuracy and gray matter in brain regions implicated in social cognition. Relative to the other groups, offenders with psychotic disorders and suicide attempts had lower empathic accuracy and smaller temporal pole volumes. Empathic accuracy and temporal pole volumes were significantly associated with suicide attempts independent of other risk variables. The results indicate that brain and behavioral correlates of social cognition may add incremental value to models of suicide risk. PMID:28065894

The neurocognitive theory of insight posits that poor insight in psychotic illnesses is related to cognitive deficits in cognitive self-appraisal mechanisms. In this paper we perform a comprehensive meta-analysis examining relationships between clinical insight and neurocognition in psychotic
Discussion: The results are suggestive of more dispersed network communication in patients with psychotic disorder, with some evidence for trait-based network alterations in high-schizotypy individuals. Dispersed communication may contribute to the clinical phenotype in psychotic disorder. In addition, higher SMP may contribute to neuro- and social cognition, independent of psychosis risk.

Although classification of mental disorders using more than clinical description would be desirable, there is scant evidence that available laboratory tests (i.e. biological indices) would provide more valid classifications than current diagnostic systems (e.g. DSM-IV). We used cluster analysis of four biological variables to classify 163 psychotic patients and 83 nonpsychiatric comparison subjects. Analyses revealed a three-cluster solution with the first cluster reflecting electrodermal deviance, the second cluster representing nondeviant biological function, and the third cluster reflecting increased nailfold plexus visibility and ocular motor dysfunction. To assess the construct validity of proband clusters we examined ocular motor performance in 156 first-degree relatives as a function of proband cluster membership. First-degree relatives of third cluster probands exhibited worse ocular motor performance than relatives of other cluster probands. Additionally, better classification sensitivity and specificity were obtained for the relatives when they were grouped by proband cluster than by proband DSM-IV diagnosis. When a single proband characteristic (i.e. eyetracking performance) was used to group relatives, classification sensitivity and specificity failed to significantly increase over grouping by proband DSM-IV diagnosis. Multivariate biologically defined clusters may offer an advantage over DSM-IV classification when examining nosology and etiology of psychotic disorders.
Full Text Available Objective: The main objective at study was to assess the communication and interaction of psychotic patient above age of 18 in 2000. Materials & Methods: The study sample consist of 80 psychotic patients (38 female and 42 male from Razi and Imam Hossein Hospital and Raad and Sina outpatient clinic, selected based on occupational therapist using the Assessment of Communication and Interaction Skills Questionnaire (ACIS. Statistical analyses of information have done by spearman coefficient correlation, Mann Whitney and Wilcoxon tests. Results: Spearman of correlation, mann-and wilcoxon Findings indicate: 1-The average grade of ACIS test in the group of schizophrenic patients were significantly lower than the group schizoaffective patients (P<0.00l. 2-The average of ACIS test in the group of inpatient was lower than the group of outpatient (p<0.00l. 3-No significant difference was found for the average grade of ACIS test in the group of male & female. Conclusion: The obtained results show the weakness of communication and interaction skills in schizophrenic patient and also inpatients. The obtained results of this investigation give useful information about the communication and interaction skill of patient to the occupational therapists but application of this instrument needs more studies.
Full Text Available Immediate treatment of first-episode psychosis is essential in order to achieve a positive outcome. However, Indonesian psychiatric patients often delay accessing health services, the reason for which is not yet fully understood. The current study aimed to understand patterns of treatment seeking and to reveal determinants of the delay in accessing psychiatric care among first-time user psychotic patients. Qualitative interviews were conducted with sixteen family members who accompanied the patients to a psychiatric hospital. Many families expressed beliefs that mental illness appertains to village sickness and not hospital sickness; therefore, they usually take the patients to traditional or religious healers before taking them to a health professional. They also identified various factors that potentially delay accessing psychiatric treatment: low literacy and beliefs about the cause of the illness, stigmatisation, the role of extended family, financial problems, and long distance to the psychiatric hospital. On the other hand, the family mentioned various factors related to timely help seeking, including being a well-educated family, living closer to health facilities, previous experience of successful psychotic therapy, and having more positive symptoms of psychosis. The findings call for mental health awareness campaigns in the community.

With the introduction of the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) numerous changes in the area of the schizophrenia spectrum and psychotic disorders have been implemented. Establishing a metastructure based on the characteristics of the spectrum of psychopathological disturbances should improve clarity. The classical subtypes of schizophrenia were eliminated and specific psychopathological dimensions for the assessment of disease severity were added. The special role of Schneiderian first rank symptoms was abandoned and a higher delineation towards schizoaffective disorders is made. The nosological status of catatonia is clarified and occurs together with a consistent use of catatonic disturbances over all chapters. The attenuated psychosis syndrome is added as a new condition for further study. The shared psychotic disorder in the sense of a folie à deux is no longer maintained. However, the initial goal to integrate more disorder-specific etiopathogenetic information into the reconceptualization could not be achieved. Contemporaneously to the development process of DSM-5 the National Institute of Mental Health (NIMH) carried out the research domain criteria project (RDoC) attempting to incorporate the current growth in knowledge of genetics, neurocognitive and cognitive sciences in future diagnostic systems. This article gives an overview of the changes that have been made within the revision process from DSM-IV to DSM-5.

To examine glutathione S-transferase (GST) deletion polymorphisms in development of early-onset severe mental disorders, with the hypothesis that patients with GSTM1-null and GSTT1-null genotypes will develop psychotic disorders at a younger age. We identified GSTM1 and GSTT1 deletion polymorphisms by multiplex polymerase chain reaction (PCR) in 93 patients with early onset severe mental disorders and 278 control individuals. The diagnoses were confirmed by Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version and Schedule for Affective Disorders and Schizophrenia-Life-Time Version (K-SADS-PL) interviews. Individuals with the GSTM1-null genotype were at 3.36-fold higher risk of developing early-onset severe mental disorders than carriers of a corresponding active genotype. The risk of those disorders was increased by 6.59-fold in patients with GSTM1-null/GSTT1-active genotype. Patients with the GSTM1-null genotype were at approximately 2-fold increased risk for developing early-onset schizophrenia-spectrum disorder (EOS), early-onset bipolar disorder (EOBD) with psychotic symptoms, or early-onset first-episode psychosis (EOFEP), compared with patients with the GSTM1-active genotype. The GSTM1-null genotype might be associated with higher risk for early onset severe mental disorders. © American Society for Clinical Pathology, 2016. All rights reserved.

This was an exploratory study of olanzapine as potential treatment for improvement in cognition in patients with Alzheimer's disease without prominent psychobehavioral symptoms. Non-psychotic/non-agitated patients (n = 268) with Alzheimer's disease, who had baseline Mini-Mental State Examination (MMSE) scores of 14-26 were randomized to treatment with olanzapine (2.5 to 7.5 mg/d) or placebo for 26 weeks. The primary objectives were to determine if treatment with olanzapine improved cognition as indexed by the Alzheimer's disease Assessment Scale for Cognition (ADAS-Cog) and the Clinician's Interview-Based Impression of Change (CIBIC) after 26 weeks of therapy. Patients treated with olanzapine vs placebo experienced significant worsening ADAS-Cog scores at weeks 12 (p = 0.03) and 26 (p = 0.004). Changes in CIBIC scores were not significantly different between treatment groups at either assessment. A post hoc analysis revealed that olanzapine-treated patients with more cognitive impairment at baseline (MMSE scores of 14-18) (n = 35) experienced significantly greater deterioration in ADAS-Cog performance than patients in the placebo group (n = 24; p cognitive impairment (n = 78, baseline MMSE scores of 23-26) between-group ADAS-Cog changes were not significant. In this 26-week study non-psychotic/non-agitated patients with Alzheimer's disease treated with olanzapine experienced significant worsening of cognition as compared to placebo.

Background Low levels of self-esteem have been implicated as both a cause and a consequence of severe mental disorders. The main aims of the study were to examine whether premorbid adjustment has an impact on the subject's self-esteem, and whether lowered self-esteem contributes to the development of delusions and hallucinations. Method A total of 113 patients from the Thematically Organized Psychosis...

Dermatomyositis is an autoimmune myopathy characterized by proximal muscle weakness, muscle inflammation, and typical skin findings. It is a rare disease with an incidence of ~1/100 000. About 15-30 % of adult-onset cases are caused by underlying malignancy and dermatomyositis can be the first symptom of undiagnosed cancer, mainly in the case of anti-transcription intermediary factor 1γ (anti-TIF-1γ) antibodies presence. TIF-1γ is a transcriptional cofactor which is implicated in TGFβ signaling pathway that controls cell proliferation, differentiation, apoptosis, and tumorigenesis. Its expression was shown to be associated with younger age, higher tumor grade, more estrogen receptor negativity, tumors larger than 2 cm, and tendency towards poor outcome in early breast cancer. No association between anti-TIF-1γ antibodies and prognosis has been proposed yet. We report a case of a 43-year-old premenopausal woman presenting with the symptoms of systemic rheumatic disease, the most prominent being a typical skin rash and muscle pain. After a series of investigations, the patient was diagnosed with anti-TIF-1γ positive dermatomyositis and concurrent triple-negative breast cancer (cT1c N3c M0) as an underlying cause. Immediate intravenous corticosteroid therapy relieved the symptoms and enabled anticancer therapy to be commenced. Considering the tumor stage, neoadjuvant therapy with 4 courses of AC (Doxorubicin/Cyclophosphamide) followed by 4 courses of Paclitaxel/Carboplatin was administered. However, no tumor regression was documented and radiotherapy was chosen as the definitive treatment. Early detection of anti-TIF-1γ autoantibodies can contribute to a rapid diagnosis of tumor-associated dermatomyositis and enable immediate anticancer treatment. We demonstrate the emerging role of anti-TIF-1γ antibodies in the diagnostics of tumor-associated dermatomyositis. Furthermore, we propose a potential role of anti-TIF-1γ antibodies as a prognostic marker in

Psychotic disorders are frequently associated with reduced concentration. As a result, reading often becomes impossible for patients with a psychotic disorder. To ascertain whether audiobooks can take the place of reading as a leisure activity for patients with a psychotic disorder. In a feasibility study we investigated whether patients suffering from a psychotic disorder found listening to audiobooks an enjoyable alternative to reading. Fifteen out of 20 participants found listening to audiobooks to be a positive experience. When reading becomes impossible for patients with a psychotic disorder, audiobooks could be a useful alternative.
The relationship between depressive symptoms and other symptom categories in schizophrenia have been studied by many authors. According to the existing studies depression in schizophrenic patients is related to the presense of positive symptoms, especifically delusions and hallucinations.As far as negative symptoms concerns it seems that there coexist with the depressive symptoms in any phase of the disease at least in a subgroup of schizophrenic patients. In addition, according to the pyramidal model of Kay, when positive and depressive symptoms coexist, they create theclinical picture of the paranoid subtype of schizophrenia. The same holds for the combination of negative and depressive symptoms, which most frequently describe the residual subtype of the disease. Extrapyramidal symptoms are side effects of antipsychotic drugs (especially the classicalones). According to the existing literature it seems that antipyramidal side effects appear more often in schizophrenic patients with depressive symptoms. The differential diagnosis of depressive symptoms in schizophrenic patients should start with the evaluation of possible presence of organiccauses like somatic disease, medication induced extrapyramidal symptoms, substance abuse. Yet, symptoms of depression need to be differentiated from the negative symptoms of schizophrenia. Psychiatric syndromes like schizoaffective disorder, bipolar disorder and depression with psychotic features need to be also considered. In this case is very important to identify accurately the duration of depressive symptoms as well as the succession of appearance of the depressive vs. psychotic symptoms. Depressive symptoms appear to be bad prognostic sign for the long-term outcome of schizophrenia, because of the increased risk for suicide but also because of the worsening of the quality of life and the general wellbeing of the schizophrenic patient. Depressive symptoms during the acute phase of the disease usually respond to

Post-traumatic stress disorder (PTSD), a disorder that develops following exposure to traumatic experience(s), is frequently associated with agitation, aggressive behavior and psychotic symptoms. Monoamine oxidase (MAO) degrades different biogenic amines and regulates mood, emotions and behavior, and has a role in the pathophysiology of various neuropsychiatric disorders. The aim of the study was to investigate the association between different symptoms occurring in PTSD [PTSD symptom severity assessed by the Clinician Administered PTSD Scale (CAPS), agitation and selected psychotic symptoms assessed by the Positive and Negative Syndrome Scale (PANSS)] and platelet MAO-B activity and/or genetic variants of MAOB rs1799836 and MAOA-uVNTR polymorphisms in 249 Croatian male veterans with PTSD. Our study revealed slightly higher platelet MAO-B activity in veterans with PTSD with more severe PTSD symptoms and in veterans with agitation, and significantly higher platelet MAO-B activity in veterans with more pronounced psychotic symptoms compared to veterans with less pronounced psychotic symptoms. Platelet MAO-B activity was associated with smoking but not with age. Genetic variants of MAOB rs1799836 and MAOA-uVNTR were not associated with agitation and selected psychotic symptoms in veterans with PTSD. A marginally significant association was found between MAOB rs1799836 polymorphism and severity of PTSD symptoms, but it was not confirmed since carriers of G or A allele of MAOB rs1799836 did not differ in their total CAPS scores. These findings suggest an association of platelet MAO-B activity, but a lack of association of MAOB rs1799836 and MAOA-uVNTR, with selected psychotic symptoms in ethnically homogenous veterans with PTSD.

In this study, out of a sample of 100 patients with psychotic disorders, 80 were investigated by array for the presence of CNVs. The assessment of the severity of psychiatric symptoms was performed using standardized instruments and ICD-10 was applied for diagnostic classification. In three patients, a submicroscopic CNV was demonstrated, one with a loss in 1q21.1 and two with a gain in 1p13.3 and 7q11.2, respectively. The association between these or other CNVs and schizophrenia or schizophrenia-like psychoses and their clinical implications still remain equivocal. While the CNV affected genes may enhance the vulnerability for psychiatric disorders via effects on neuronal architecture, these insights have not resulted in major changes in clinical practice as yet. Therefore, genome-wide array analysis should presently be restricted to those patients in whom psychotic symptoms are paired with other

Studies on whether the co-occurrence of psychotic experiences (PEs) and depression confers a more pronounced decrement in health status and function compared with depression alone are scarce in the general adult population. Data on 195 479 adults aged ⩾18 years from the World Health Survey were analysed. Using the World Mental Health Survey version of the Composite International Diagnostic Interview (CIDI), depression in the past 12 months was categorized into four groups: depressive episode, brief depressive episode, subsyndromal depression, and no depression. Past 12-month psychotic symptoms were assessed using four questions on positive symptoms from the CIDI. Health status across seven domains (cognition, interpersonal activities, sleep/energy, self-care, mobility, pain/discomfort, vision) and interviewer-rated presence of a mental health problem were assessed. Multivariable logistic and linear regression analyses were performed to assess the associations. When compared with those with no depression, individuals with depression had higher odds of reporting at least one PE, and this was seen across all levels of depression severity: subsyndromal depression [odds ratio (OR) 2.38, 95% confidence interval (CI) 2.02-2.81], brief depressive episode (OR 3.84, 95% CI 3.31-4.46) and depressive episode (OR 3.75, 95% CI 3.24-4.33). Having coexisting PEs and depression was associated with a higher risk for observable illness behavior and a significant decline in health status in the cognition, interpersonal activities and sleep/energy domains, compared with those with depression alone. This coexistence of depression and PEs is associated with more severe social, cognitive and sleep disturbances, and more outwardly apparent illness behavior. Detecting this co-occurrence may be important for treatment planning.

Social interaction might lead to increased stress levels in patients with psychotic disorders. Impaired social stress tolerance is critical for social functioning and closely linked with symptom relapse and hospitalization. We present an interactive office built-up in virtual reality (VR). Patients with psychotic disorders (PP, N = 26 including N = 5 dropouts) and matched healthy controls (HC, N = 20) were examined with a VR simulating an open-plan office. In a randomized, controlled cross-over design, participants were introduced to virtual co-workers (avatars) and requested to ask them for task assistance. Social feedback in each of the two sessions was either cooperative or rejective in randomized order. The office environment was tolerable for most PP and all HC, five PP and none of the HC dropped out for any reason. Drop-outs reported simulator sickness, influence on thoughts and symptom exacerbations. Statistical trends indicated heightened paranoid ideations for PP after social rejection. State measures of paranoid ideations showed high convergent validity with conventional measures of delusions. Of note, measures of presence were higher for PP than for HC. The exploratory design limits the robustness of the findings. Only statistical trends on paranoid ideation were found. The use of VR to assess the effects of social rejection is feasible and tolerable for most PP (87%). However, its implementation for PP is challenged by increased simulator sickness and an additional stress load for some patients. Further studies continuing on these first results that point towards an increased paranoid ideation evoked by negative social feedback and generally higher subjective presence are needed.

Early detection of psychosis is an important issue in current research. Early intervention helps to improve the outcome of the disorder. Therefore, a comprehensive examination in large populations, necessary as it might be, is economically almost not feasible. A screening via self-report is more practicable as it helps focus on individuals with high symptom loads. To examine aspects of validity of the Self-screen-Prodrome (SPro) as a new screening tool for prodromal states of psychosis in a military sample. 938 Swiss conscripts were assessed with the SPro, the Eppendorf Schizophrenia-Inventory (ESI) and the Symptom-Checklist-90-Revised (SCL-90-R). Conscripts with potential psychosis-like pathology (T-transformed Severity Index of the SCL-90-R-subscales Psychoticism [PSYC] and Paranoid Ideation [PARA]≥63) were compared with those not meeting the criteria of this condition (non-cases). Both groups (cases and non-cases) showed significant differences in their mean scores on SPro and ESI, although only the SPro had satisfactory effect sizes. In hierarchic logistic regression models the SPro turned out to be highly predictive for caseness while ESI-scales were not significant. A cut-off score of ≥2 on the SPro subscale for psychotic risk (SPro-Psy-Risk) was found to identify caseness best with a sensitivity of 74% and a specificity of 61%. The SPro has proven to be a valid and very economic screening tool for general and prodromal pathology in large populations. Copyright © 2010 Elsevier B.V. All rights reserved.

Nineteen patients seen at a psychiatric emergency service with amphetamine- or cocaine-induced psychotic disorder were assessed with structured interviews, chart review, and blood and urine testing. All had a predominance of positive symptoms from the Positive and Negative Syndrome Scale (PANSS). However, some subjects had substantial Negative Scale scores (26%), bizarre delusions (95%), and Schneiderian hallucinations (63%), mimicking a broad range of schizophrenic symptoms. Several PANSS scores were correlated with treatment intensity: Positive score with seclusion hours, General Psychopathology and Negative scores with hospitalization length, and General Psychopathology score with neuroleptic dose. Presenting symptoms may help in treatment planning.

Meditation is proposed as an anti-stress practice lowering allostatic load and promoting well-being, with brief formats providing some of the benefits of longer interventions. PsychoNeuroEndocrinoImmunology-based meditation (PNEIMED) combines the teaching of philosophy and practice of Buddhist meditation with a grounding in human physiology from a systemic and integrative perspective. We evaluated the effects of four-day PNEIMED training (30 h) on subjective and objective indices of stress in healthy adults. A non-randomized, controlled, before-and-after study was conducted. Participants (n = 125, mostly health practitioners) answered a questionnaire rating stress symptom before (T0) and after (Tf) a PNEIMED course. In an additional sample (n = 40; smokers, overweight persons, women taking contraceptives, and subjects with oral pathologies were excluded), divided into PNEIMED-attending (intervention, n = 21) and non-meditating (control, n = 19) groups, salivary cortisol was measured upon awakening and during a challenging mental task. Self-rated distress scores were highly reduced after the PNEIMED course. In the intervention group, improvement of psychological well-being was accompanied by decrease in cortisol levels at awakening. No T0-vs-Tf changes in distress scores and morning cortisol were found in controls. Based on baseline-to-peak increment of cortisol response at T0, 26 subjects (n = 13 for each group) were classified as task-responders. The amplitude and duration of the cortisol response decreased after PNEIMED, whereas no effects were found in controls. Brief PNEIMED training yields immediate benefits, reducing distress symptoms and adrenocortical activity under basal and stimulated conditions. PNEIMED may represent an effective practice to manage stress and anxiety, particularly among subjects facing a multitude of job-related stressors, such as healthcare workers.

Evidence suggests that in affective, non-psychotic disorders: (i) environmental exposures increase risk of subthreshold psychotic experiences (PEs) and strengthen connectivity between domains of affective and subthreshold psychotic psychopathology; and (ii) PEs are a marker of illness severity. In 3021 adolescents from the Early Developmental Stages of Psychopathology cohort, we tested whether the association between PEs and presence of DSM-IV mood disorder (MD)/obsessive-compulsive disorder (OCD) would be moderated by risk factors for psychosis (cannabis use, childhood trauma and urbanicity), using the interaction contrast ratio (ICR) method. Furthermore, we analysed whether the interaction between environment and PEs was mediated by non-psychotic psychopathology. The association between PEs and MD/OCD was moderated by urbanicity (ICR = 2.46, p = 0.005), cannabis use (ICR = 3.76, p = 0.010) and, suggestively, trauma (ICR = 1.91, p = 0.063). Exposure to more than one environmental risk factor increased the likelihood of co-expression of PEs in a dose-response fashion. Moderating effects of environmental exposures were largely mediated by the severity of general non-psychotic psychopathology (percentage explained 56-68%, all p psychopathology. The findings are compatible with a relational model of psychopathology in which more severe clinical states are the result of environment-induced disturbances spreading through a psychopathology network.

Records of all 154 psychotic patients first admitted to a psychiatric hospital in 1925 were rated according to a checklist of 33 dichotomous items expected to characterize cycloid and schizoaffective psychosis; 64 cases satisfied 5 or more items. Among them, 34 were globally judged as cycloid and showed a favourable outcome when followed up. The remaining 30 cases were used as a contrast sample, consisting of schizoaffective psychotics with an unfavourable outcome and schizophrenics and affective patients who shared some symptoms with the experiment group. Six symptoms significantly more frequent in the cycloid group were all characteristic for confusional and anxiety or happiness psychoses in the sense of Leonhard. Happiness-ecstacy and global altruism were exclusively recorded in cycloid psychosis. A discriminant analysis yielded a significant proportion of correct predictions. The result was thought to be relevant for differential therapeutic strategies.

Fracture risk is increased in patients with schizophrenia, who often receive long-term therapy with anti-psychotic drugs. The mechanisms by which skeletal fragility is increased in patients with psychosis include increased risk of falling, but direct skeletal toxicity of anti-psychotic drugs is a possibility that has not been investigated. We examined the skeletal effects, in vivo and in vitro, of a typical anti-psychotic drug, haloperidol, which primarily inhibits dopaminergic signaling, and an atypical anti-psychotic drug, clozapine, which predominantly inhibits serotonergic signaling. In growing rats, 42 days of clozapine treatment reduced whole body bone mineral density by 15% (Pactions to reduce osteoblast growth and function. Long-term administration of clozapine may therefore negatively affect bone health, and clinical studies to investigate this possibility are warranted. Copyright © 2010 Elsevier B.V.

functionally impaired because of evolving FEP although school is a key setting for promoting positive mental health, fostering resilience, detecting and responding to emerging mental ill health. So, people with psychotic illness have low levels of secondary school completion. School dropout has been defined as leaving education without obtaining a minimal credential, most often a higher secondary education diploma. In France, the school is compulsory up to the age of 16. Consequences are significant: among young people without a degree out of initial training for one to four years and present on the labour market, 47% are unemployed. School dropout depends on a number of factors, including grades, family and social environment and the relationship with the school, but also the emergence of psychiatric disorders. For first episode psychotic patients, age of onset, lack of family support, longer duration of psychosis, levels of premorbid global functioning and education, negative and cognitive symptoms, addictions, depressive comorbidities and stigma plays an important role in school dropout. However, young adults have historically received less treatment than expected considering prevalence of mental illness at that age. In the last few decades, early intervention programs for psychosis have been developed all around the world in order to promote rehabilitation and prevent long-term disabilities. Early intervention programs focus on the special needs of young people and their families and engage in some form of assertive community treatment, which attempts to treat patients in the community rather than using inpatient services. For early intervention in psychosis programs, the goal is to keep patients engaged with treatment, prevent them from further psychotic episodes and hospitalizations and promote rehabilitation. The additional services of an early intervention program include staff specialized in psychosis treatment, family/group/individual counseling sessions, assertive

Psychotic experiences are associated with a number of poor clinical outcomes, including multimorbid psychopathology, suicidal behavior, and poor treatment response. We wished to investigate the relationship between psychotic experiences and disability, including the following domains: cognition, mobility, self-care, social interaction, role functioning, and days out of role. We used three nationally representative and racially/ethnically diverse samples of the general US adult population: the National Comorbidity Survey Replication (NCS-R), the National Latino and Asian American Survey (NLAAS), and the National Survey of American Life (NSAL). Multi-variable logistic regression analyses were used to assess the associations between lifetime psychotic experiences (visual and auditory hallucinatory experiences and delusional ideation; WHO Composite International Diagnostic Interview psychosis screen) and 30-day impairments in functioning across disability domains (using the WHO Disability Assessment Schedule II). In all three samples, models were adjusted for socio-demographics and co-occurring psychiatric disorders. In the NCS-R, models were also adjusted for chronic health conditions. Across all three studies, our adjusted models showed that people with disability had anywhere from about 1.5 to over 3 times the odds of reporting lifetime psychotic experiences, depending on the domain. This was true for each disability domain, except self-care in the NLAAS and in the NSAL. Psychotic experiences are markers of risk for disability across a wide range of domains. This may explain the elevated rates of service utilization among individuals who report psychotic experiences and supports the need to assess for and respond to psychotic experiences even in the absence of psychotic disorder.

To examine associations between specific parasomnias and psychotic experiences in childhood. Birth cohort study. Information on the presence of frequent nightmares in children was obtained prospectively from mothers during multiple assessments conducted when children were aged between 2.5 and 9 y. Children were interviewed at age 12 y about nightmares, night terrors, sleepwalking, and psychotic experiences (delusions, hallucinations, and thought interference) occurring in the previous 6 mo. Assessments were completed in participants' homes or a University clinic within the UK. There were 6,796 children (3,462 girls, 50.9%) who completed the psychotic experiences interview. Children who were reported by their mothers as experiencing frequent nightmares between 2.5 and 9 y of age were more likely to report psychotic experiences at age 12 y, regardless of sex, family adversity, emotional or behavioral problems, IQ and potential neurological problems (odds ratio (OR) = 1.16, [95% confidence intervals (CI) = 1.00, 1.35], P = 0.049). Children reporting any of the parasomnias at age 12 y also had higher rates of concurrent psychotic experiences than those without such sleeping problems, when adjusting for all confounders (OR = 3.62 [95% CI = 2.57, 5.11], P night waking were not found to be associated with psychotic experiences at age 12 y when controlling for confounders. Nightmares and night terrors, but not other sleeping problems, in childhood were associated with psychotic experiences at age 12 years. These findings tentatively suggest that arousal and rapid eye movement forms of sleep disorder might be early indicators of susceptibility to psychotic experiences.

Background Many patients with a non-affective psychotic disorder suffer from impairments in social functioning and social cognition. To target these impairments, mentalization-based treatment for psychotic disorder, a psychodynamic treatment rooted in attachment theory, has been developed. It is expected to improve social cognition, and thereby to improve social functioning. The treatment is further expected to increase quality of life and the awareness of having a mental disorder, and to red...

The mechanisms underlying distortions in sense of agency, i.e. the experience of controlling one's own actions and their consequences, in schizophrenia are not fully understood and have barely been investigated in patients classified as being in a putative psychotic prodrome. This study aims to expound the contribution of early and late illness-related processes. Thirty schizophrenia patients, 30 putatively prodromal patients and 30 healthy controls were instructed to reproduce a computer-generated series of drum sounds on a drum pad. While tapping, subjects heard either their self-produced tones or a computer-controlled reproduction of the drum tone series that used either exactly the same, an accelerated or decelerated tempo. Subjects had to determine the source of agency. Results show similar significant impairments in assigning the source of agency under ambiguous conditions in schizophrenia and putatively prodromal patients and an exaggerated self-attribution bias, both of which were significantly correlated with increased (ego-)psychopathology. Patient groups, however, benefited significantly more than controls from additional sensorimotor cues to agency. Sensorimotor input seems to be a compensatory mechanism involved in correctly attributing agency. We deduce that altered awareness of agency may hold promise as an additional risk factor for psychosis. Copyright © 2010 Elsevier Ltd. All rights reserved.

The way we formulate a mathematical model of an infectious disease to capture symptomatic and asymptomatic transmission can greatly influence the likely effectiveness of vaccination in the presence of vaccine effect for preventing clinical illness. The present study aims to assess the impact of model building strategy on the epidemic threshold under vaccination. We consider two different types of mathematical models, one based on observable variables including symptom onset and recovery from clinical illness (hereafter, the "observable model") and the other based on unobservable information of infection event and infectiousness (the "unobservable model"). By imposing a number of modifying assumptions to the observable model, we let it mimic the unobservable model, identifying that the two models are fully consistent only when the incubation period is identical to the latent period and when there is no pre-symptomatic transmission. We also computed the reproduction numbers with and without vaccination, demonstrating that the data generating process of vaccine-induced reduction in symptomatic illness is consistent with the observable model only and examining how the effective reproduction number is differently calculated by two models. To explicitly incorporate the vaccine effect in reducing the risk of symptomatic illness into the model, it is fruitful to employ a model that directly accounts for disease progression. More modeling studies based on observable epidemiological information are called for.

Childhood adversity has been associated with onset of psychosis in adulthood but these studies have used only general definitions of this environmental risk indicator. Therefore, we sought to explore the prevalence of more specific adverse childhood experiences amongst those with and without psychotic disorders using detailed assessments in a large epidemiological case-control sample (AESOP). Data were collected on 182 first-presentation psychosis cases and 246 geographically matched controls in two UK centres. Information relating to the timing and frequency of exposure to different types of childhood adversity (neglect, antipathy, physical and sexual abuse, local authority care, disrupted living arrangements and lack of supportive figure) was obtained using the Childhood Experience of Care and Abuse Questionnaire. Psychosis cases were three times more likely to report severe physical abuse from the mother that commenced prior to 12 years of age, even after adjustment for other significant forms of adversity and demographic confounders. A non-significant trend was also evident for greater prevalence of reported severe maternal antipathy amongst those with psychosis. Associations with maternal neglect and childhood sexual abuse disappeared after adjusting for maternal physical abuse and antipathy. Paternal maltreatment and other forms of adversity were not associated with psychosis nor was there evidence of a dose-response effect. These findings suggest that only specific adverse childhood experiences are associated with psychotic disorders and only in a minority of cases. If replicated, this greater precision will ensure that research into the mechanisms underlying the pathway from childhood adversity to psychosis is more fruitful.
Full Text Available O esclarecimento da natureza do delírio conforme uma teoria da referência é o objetivo desse trabalho. A categoria da referência é investigada à luz da filosofia analítica da linguagem e da psicopatologia. Toda a reflexão teórica se desenvolve a partir da análise de excertos da fala de pacientes psicóticos e constata-se que o pensamento psicótico é caracterizado pela quebra do processo habitual de referenciação. É demonstrada a insuficiência de se conceber o delírio como apenas um erro judicativo e a necessidade de considerar as asserções delirantes dentro dos contextos mais amplos da linguagem ordinária e assim evidenciar a sua especificidade.The aim of the present paper is to describe the nature of delusion according to a theory of reference. The category of reference is investigated based in the analytical philosophy of language and in psychopathology. All theoretical reflection begins with the analysis of speech excerpts of psychotic patients and it is verified that psychotic thought is distinguished by the breaking of the usual process of referentiation. It is shown the insufficiency of conceiving delusion as only a judicative mistake and the necessity on considering delusional propositions under the more ample contexts of ordinary language and so clear up its specificity.

The crowns of five canopy dominant black cherry (Prunus serotina Ehrh.), five white ash (Fraxinus americana L.), and six red maple (Acer rubrum L.) trees on naturally differing environmental conditions were accessed with scaffold towers within a mixed hardwood forest stand in central Pennsylvania. Ambient ozone concentrations, meteorological parameters, leaf gas exchange and leaf water potential were measured at the sites during the growing seasons of 1998 and 1999. Visible ozone-induced foliar injury was assessed on leaves within the upper and lower crown branches of each tree. Ambient ozone exposures were sufficient to induce typical symptoms on cherry (0-5% total affected leaf area, LAA), whereas foliar injury was not observed on ash or maple. There was a positive correlation between increasing cumulative ozone uptake (U) and increasing percent of LAA for cherry grown under drier site conditions. The lower crown leaves of cherry showed more severe foliar injury than the upper crown leaves. No significant differences in predawn leaf water potential (ψ L ) were detected for all three species indicating no differing soil moisture conditions across the sites. Significant variation in stomatal conductance for water vapor (g wv ) was found among species, soil moisture, time of day and sample date. When comparing cumulative ozone uptake and decreased photosynthetic activity (P n ), red maple was the only species to show higher gas exchange under mesic vs. drier soil conditions (P wv and P n demonstrate the strong influence of heterogeneous environmental conditions within forest canopies. - Within the heterogeneous environment of a mature forest, many factors in addition to soil moisture play a significant role in determining exposure/response relationships to ozone

Psychosis prevention and early intervention efforts in schizophrenia have focused increasingly on sub-threshold psychotic symptoms in adolescents and young adults. Although many youth report symptom onset prior to adolescence, the childhood incidence of prodromal-level symptoms in those with schizophrenia or related psychoses is largely unknown. This study reports on the retrospective recall of prodromal-level symptoms from 40 participants in a first-episode of schizophrenia (FES) and 40 participants at "clinical high risk" (CHR) for psychosis. Onset of positive and non-specific symptoms was captured using the Structured Interview for Prodromal Syndromes. Frequencies are reported according to onset during childhood (prior to age 13), adolescence (13-17), or adulthood (18+). Childhood-onset of attenuated psychotic symptoms was not rare. At least 11% of FES and 23% of CHR reported specific recall of childhood-onset of unusual or delusional ideas, suspiciousness, or perceptual abnormalities. Most recalled experiencing non-specific symptoms prior to positive symptoms. CHR and FES did not differ significantly in the timing of positive and non-specific symptom onset. Other than being younger at assessment, those with childhood onset did not differ demographically from those with later onset. Childhood-onset of initial psychotic-like symptoms may be more common than previous research has suggested. Improved characterization of these symptoms and a focus on their predictive value for subsequent schizophrenia and other major psychoses are needed to facilitate screening of children presenting with attenuated psychotic symptoms. Accurate detection of prodromal symptoms in children might facilitate even earlier intervention and the potential to alter pre-illness trajectories. Copyright © 2014 Elsevier B.V.

Full Text Available Abstract Background Immigration status is a significant risk factor for psychotic disorders, and a number of studies have reported more severe positive and affective symptoms among immigrant and ethnic minority groups. We investigated if perceived discrimination was associated with the severity of these symptoms among immigrants in Norway with psychotic disorders. Methods Cross-sectional analyses of 90 immigrant patients (66% first-generation, 68% from Asia/Africa in treatment for psychotic disorders were assessed for DSM-IV diagnoses with the Structured Clinical Interview for DSM Disorders (SCID-I, sections A-E and for present symptom severity by The Structured Positive and Negative Syndrome Scale (SCI-PANSS. Perceived discrimination was assessed by a self-report questionnaire developed for the Immigrant Youth in Cultural Transition Study. Results Perceived discrimination correlated with positive psychotic (r = 0.264, p Conclusions Among immigrants with psychotic disorders, visible minority status was associated with perceived discrimination and with more severe positive and depression/anxiety symptoms. These results suggest that context-specific stressful environmental factors influence specific symptom patterns and severity. This has important implications for preventive strategies and treatment of this vulnerable patient group.

Sleep disturbances are commonly reported in the psychosis prodrome, but rarely explored in relation to psychotic experiences. To investigate the relationship between specific parasomnias (nightmares, night terrors and sleepwalking) in childhood and later adolescent psychotic experiences. The sample comprised 4720 individuals from a UK birth cohort. Mothers reported on children's experience of regular nightmares at several time points between 2 and 9 years. Experience of nightmares, night terrors and sleepwalking was assessed using a semi-structured interview at age 12. Psychotic experiences were assessed at ages 12 and 18 using a semi-structured clinical interview. There was a significant association between the presence of nightmares at 12 and psychotic experiences at 18 when adjusted for possible confounders and psychotic experiences at 12 (OR = 1.62, 95% CI 1.19-2.20). The odds ratios were larger for those who reported persistent psychotic experiences. The presence of nightmares might be an early risk indicator for psychosis. © The Royal College of Psychiatrists 2015.

The authors consider that the Freudian theory of dreams is not directly applicable to psychotic and borderline patients with their constantly varying states of mental integration. Because these patients' dreams lack associations, the usual psychoanalytic approach cannot be used to ascertain their meaning. After reviewing the literature on the specific quality of dreams in the psychotic state, the authors point out that such dreams have nothing to do with the metaphorical language of the dream work but instead express the concreteness of the hallucinatory construction. For this reason, a dream's meaning may fail to be understood by the patient even if it seems clear to an observer. Yet the analyst's reception of a 'psychotic dream' is a unique and essential source of valuable information on the manner of construction of the delusional system, allowing analytic work on the psychotic nucleus. In the authors' view, such dreams may help the analyst and the patient--while still lucid--to acquire insight, thus affording a stable foundation for emergence from psychosis. The paper includes some case histories, in one of which a psychotic female patient is enabled by work on dreams to reconstruct a psychotic episode and thereby to ward off an imminent fresh lapse into psychosis.

Objectives: It remains unclear how augmenting anti-psychotic medications with anti-depressants impacts primary positive and negative symptoms of schizophrenia. In this study, we used data collected from a randomized trial comparing citalopram to placebo for management of subsyndromal depression (SSD) in schizophrenia and schizoaffective disorder, to assess the effects of antidepressant augmentation on positive and negative symptoms. Materials and Methods: Participants in this study conducted at the University of California, San Diego and the University of Cincinnati, were persons with schizophrenia or schizoaffective disorder aged 40 or older and who met study criteria for SSD. Patients were randomly assigned to flexible-dose treatment with citalopram or placebo augmentation of their current anti-psychotic medication. Analysis of covariance was used to compare changes in po
