    Full Text Available Low vitamin D levels have been associated with depressive symptoms in population-based studies and non-clinical samples as well as with clinical depression. This study aimed to examine the association of vitamin D levels with the severity and dimensions of depressive symptoms in hospitalized patients with a current episode of depression taking into account confounding variables.We investigated 380 patients (mean age 47 ± 12 years, 70% women who were consecutively hospitalized with a main diagnosis of an ICD-10 depressive episode. All patients self-rated depressive symptom severity with the Hospital Anxiety and Depression Scale (HADS-D, the Beck Depression Inventory-II (BDI-II, and the Brief Symptom Inventory. A principal component analysis was performed with all 34 items of these questionnaires and serum levels of 25-hydroxyvitamin D3 (25-OH D were measured.Vitamin D deficiency ( 75 nmol/l were present in 55.5%, 31.8% and 12.6%, respectively, of patients. Patients with vitamin D deficiency scored higher on the HADS-D scale and on an anhedonia symptom factor than those with insufficient (p-values ≤ 0.023 or sufficient (p-values ≤ 0.008 vitamin D. Vitamin D deficient patients also scored higher on the BDI-II scale than those with sufficient vitamin D (p = 0.007; BDI-II cognitive/affective symptoms, but not somatic/affective symptoms, were higher in patients with vitamin D deficiency (p = 0.005 and insufficiency (p = 0.041 relative to those with sufficient vitamin D. Effect sizes suggested clinically relevant findings.Low vitamin D levels are frequent in hospitalized patients with a current episode of depression. Especially 25-OH D levels < 50 nmol/l were associated with cognitive/affective depressive symptoms, and anhedonia symptoms in particular.

    At present, little is still known about the link between depression, memory and executive functioning. This study examined whether there are memory-related impairments in depressed patients and whether the size of such deficits depends on the age group and on specific types of cognitive measures. Memory performances of 215 clinically depressed patients were compared to the data of a matched control sample. Regression analyses were performed to determine the extent to which executive dysfunctions contributed to episodic memory impairments. When compared with healthy controls, significantly lower episodic memory and executive functioning performances were found for depressed patients of all age groups. Effect sizes appeared to vary across different memory and executive functioning measures. The extent to which executive dysfunctions could explain episodic memory impairments varied depending on the type of measure examined. These findings emphasise the need to consider memory-related functioning of depressed patients in the context of therapeutic treatments.

    Most research to date on the role of maltreatment experiences in depression has focused on physical and sexual maltreatment. However, several researchers have theorized that emotional maltreatment may be more strongly linked to depression. Furthermore, prospective studies in this area are lacking. This study addressed these issues by examining whether experiences of current emotional maltreatment predicted the development of new prospective episodes of major (MD) or minor depression (MiD), and the subtype of hopelessness depression (HD) in young adults. It also assessed whether current emotional maltreatment from peers and from authority figures separately predicted the occurrence of depressive episodes. One hundred and sixty-five participants from the Cognitive Vulnerability to Depression Project were followed prospectively for 2.5 years. Current emotional maltreatment and new depressive episodes were assessed with life event and diagnostic interviews administered every 6 weeks. Greater overall emotional maltreatment predicted shorter time to onset of new MD, MiD, and HD episodes. Peer- and authority-perpetrated emotional maltreatment separately predicted shorter time to development of new HD episodes. Greater emotional maltreatment in young adults prospectively predicts onset of depression, particularly HD. These findings highlight the importance of adult emotional maltreatment experiences in determining targets for prevention and treatment. (c) 2009 Wiley-Liss, Inc.

  6. Mindfulness-based interventions for people diagnosed with a current episode of an anxiety or depressive disorder: a meta-analysis of randomised controlled trials.

    Full Text Available OBJECTIVE: Mindfulness-based interventions (MBIs can reduce risk of depressive relapse for people with a history of recurrent depression who are currently well. However, the cognitive, affective and motivational features of depression and anxiety might render MBIs ineffective for people experiencing current symptoms. This paper presents a meta-analysis of randomised controlled trials (RCTs of MBIs where participants met diagnostic criteria for a current episode of an anxiety or depressive disorder. METHOD: Post-intervention between-group Hedges g effect sizes were calculated using a random effects model. Moderator analyses of primary diagnosis, intervention type and control condition were conducted and publication bias was assessed. RESULTS: Twelve studies met inclusion criteria (n = 578. There were significant post-intervention between-group benefits of MBIs relative to control conditions on primary symptom severity (Hedges g = -0.59, 95% CI = -0.12 to -1.06. Effects were demonstrated for depressive symptom severity (Hedges g = -0.73, 95% CI = -0.09 to -1.36, but not for anxiety symptom severity (Hedges g = -0.55, 95% CI = 0.09 to -1.18, for RCTs with an inactive control (Hedges g = -1.03, 95% CI = -0.40 to -1.66, but not where there was an active control (Hedges g = 0.03, 95% CI = 0.54 to -0.48 and effects were found for MBCT (Hedges g = -0.39, 95% CI = -0.15 to -0.63 but not for MBSR (Hedges g = -0.75, 95% CI = 0.31 to -1.81. CONCLUSIONS: This is the first meta-analysis of RCTs of MBIs where all studies included only participants who were diagnosed with a current episode of a depressive or anxiety disorder. Effects of MBIs on primary symptom severity were found for people with a current depressive disorder and it is recommended that MBIs might be considered as an intervention for this population.

    Full Text Available Abstract Background The Mood Disorder Questionnaire (MDQ is a well-recognized screening tool for bipolar disorder, but its Chinese version needs further validation. This study aims to measure the accuracy of the Chinese version of the MDQ as a screening instrument for bipolar disorder (BPD in a group of patients with a current major depressive episode. Methods 142 consecutive patients with an initial DSM-IV-TR diagnosis of a major depressive episode were screened for BPD using the Chinese translation of the MDQ and followed up for one year. The final diagnosis, determined by a special committee consisting of three trained senior psychiatrists, was used as a 'gold standard' and ROC was plotted to evaluate the performance of the MDQ. The optimal cut-off was chosen by maximizing the Younden's index. Results Of the 142 patients, 122 (85.9% finished the one year follow-up. On the basis of a semi-structured clinical interview 48.4% (59/122 received a diagnosis of unipolar depression (UPD, 36.9% (45/122 BPDII and 14.8% (18/122 BPDI. At the end of the one year follow-up,9 moved from UPD to BPD, 2 from BPDII to UPD, 1 from BPDII to BPDI, the overall rate of initial misdiagnosis was 16.4%. MDQ showed a good accuracy for BPD: the optimal cut-off was 4, with a sensitivity of 0.72 and a specificity of 0.73. When BPDII and BPDI were calculated independently, the optimal cut-off for BPDII was 4, with a sensitivity of 0.70 and a specificity of 0.73; while the optimal cut-off for BPDI was 5, with a sensitivity of 0.67 and a specificity of 0.86. Conclusions Our results show that the Chinese version of MDQ is a valid tool for screening BPD in a group of patients with current depressive episode on the Chinese mainland.

    Disturbed interpersonal relationships specific to borderline personality disorder (BPD) suggest biased processing of social information. The goal of this study was to examine alterations in mental state decoding (MSD) and their associations with early maladaptive schemas (EMS) that may lead to the misinterpretation of incoming information. In addition, the authors' aim was to evaluate the effects of a co-occurring current major depressive episode (MDE) on the MSD performance of BPD patients. Seventy-eight BPD patients (34 with MDE) and 76 matched healthy controls (HC) were assessed for Reading the Mind in the Eyes Test (RMET) and the level of EMS. The authors found that impairment in the total RMET performance, as well as specific impairment regarding the recognition of positive and neutral items, was associated with EMS, and enhanced vigilance to negative mental states was characteristic to BPD with MDE. Results suggest that MSD ability is altered in two independent ways in BPD.

    It is unknown whether a history of depression, anxiety disorders, or comorbid depression and anxiety affects subsequent health-related quality of life (HRQOL) during midlife in women when vasomotor symptoms (VMS) and sleep disturbance commonly disrupt QOL. To evaluate whether previous affective illness is associated with low HRQOL during midlife in the absence of current illness episodes and whether low HRQOL is explained by VMS or sleep disruption. Longitudinal, community-based study. Western Pennsylvania. A total of 425 midlife women in the Study of Women's Health Across the Nation who completed the Structured Clinical Interview for DSM-IV (SCID) and the 36-Item Short Form Health Survey (SF-36) annually during 6 years of follow-up. Scores on the SF-36 scales of social functioning (SF), role-emotional (RE), role-physical (RP), body pain (BP), and vitality. Ninety-seven women (22.8%) had comorbid affective illness histories, 162 (38.1%) had previous depression only, and 21 (4.9%) had previous anxiety only. Those with comorbid illness histories and depression alone were more likely to report low HRQOL on the SF, RE, RP, and BP domains (odds ratio [OR] = 2.31-3.54 and 1.59-2.28, respectively) than were women with neither disorder. After adjustment for VMS and sleep disturbance, the comorbid group continued to have low HRQOL on these domains (OR = 2.13-3.07), whereas the association was significant on SF and BP only for the depression-alone group (OR = 2.08 and 1.95, respectively). Compared with women with neither disorder, the anxiety-only group had low HRQOL on the RP domain (OR = 2.60). Sleep disturbance, but not VMS, was independently associated with low HRQOL on all the domains except RE. A history of both depression and anxiety has the most robust negative effect on HRQOL in women during midlife, an association not explained by VMS or sleep disturbance. For the depression-alone group, sleep disturbance may partially explain the negative impact of previous

    Psychotic bipolar depressive episodes remain remarkably understudied despite being common and having a significant impact on bipolar disorder. The aim of this study is to identify the characteristics of depressed bipolar patients with current psychosis compared to those without psychosis. We used baseline data of a comparative effectiveness study of lithium and quetiapine for bipolar disorder (the Bipolar CHOICE study) to compare demographic, clinical, and functioning variables between those with and without psychotic symptoms. Of the 482 participants, 303 (62.9%) were eligible for the present study by meeting DSM-IV criteria for an acute bipolar depressive episode. Univariate analyses were conducted first, and then included in a model controlling for symptom severity. The sample was composed mostly of women (60.7%) and the mean age was 39.5±12.1 years. Psychosis was present in 10.6% (n=32) of the depressed patients. Psychotic patients had less education, lower income, and were more frequently single and unemployed. Psychosis was also associated with a more severe depressive episode, higher suicidality, more comorbid conditions and worse functioning. Most group differences disappeared when controlling for depression severity. Only outpatients were included and the presence of psychosis in previous episodes was not assessed. Psychosis during bipolar depressive episodes is present even in an outpatient sample. Psychotic, depressed patients have worse illness outcomes, but future research is necessary to confirm if these outcomes are only associated with the severity of the disorder or if some of them are independent of it.

    Full Text Available Cognitive reactivity to sad mood refers to the degree to which a mild dysphoric state reactivates negative thinking patterns. In this research, the contribution of the history of depression, the length of the current depressive episode and the intensity of the depressive symptoms were assessed in explaining the cognitive reactivity to sad mood measured with the Leiden Index of Depression Sensitivity (LEIDS. The sample consisted of 123 depressed outpatients. The results of principal components analysis suggested a three-factor solution of the LEIDS. The intensity of depressive symptoms, the history of depression and the length of the current depressive episode were all significant in explaining cognitive reactivity to sad mood. We have also found out a significant effect of interaction of the history of depression and the length of the current depressive episode, which demonstrated that a prolonged depression does not induce a stronger cognitive reactivity to sad mood during the relapse of a depressive episode, while during the first depressive episode a longer duration of depression does induce a stronger cognitive reactivity. Such a result demonstrates that the length of the first depressive episode, regardless of its intensity, is crucially important for the formation of cognitive reactivity.

    The aim of the present study was to investigate the distribution of suicide attempts across the depressive episodes in suicides and controls with a severe depression. A blind record evaluation was performed of 100 suicide victims and matched controls admitted to the Department of Psychiatry between 1956 and 1969 and monitored to 2006. There was a similar number of episodes in suicides and controls and in the early episodes a similar number of suicide attempts in both groups. However, in the later episodes future suicides showed more suicide attempts as compared to controls. This was found for unipolar depression only. This difference was found despite previously shown similar rates of adequate treatment and improvement. In conclusion, more depressive episodes including suicide attempts appeared to be related to suicide.

    Objectives To describe the duration of bipolar I major and minor depressive episodes and factors associated with time to recovery. Method 219 participants with bipolar I disorder based on Research Diagnostic Criteria analogs to DSM-IV-TR criteria were recruited from 1978–1981 and followed for up to 25 years. Psychopathology was assessed with the Longitudinal Interval Follow-up Evaluation. The probability of recovery over time from multiple successive depressive episodes was examined with survival analytic techniques, including mixed-effects grouped-time survival models. Results The median duration of major depressive episodes was 14 weeks, and over 70% recovered within 12 months of onset of the episode. The median duration of minor depressive episodes was 8 weeks, and approximately 90% recovered within 6 months of onset of the episode. Aggregated data demonstrated similar durations of the first three major depressive episodes. However, for each participant with multiple episodes of major depression or minor depression, the duration of each episode was not consistent (intraclass correlation coefficient=0.07 and 0.25 for major and minor depression, respectively). The total number of years in episode over follow-up with major plus minor depression prior to onset of a major depressive episode was significantly associated with a decreased probability of recovery from that episode; with each additional year, the likelihood of recovery was reduced by 7% (hazard ratio: 0.93, 95% CI: 0.89–0.98, p=0.002). Conclusions Bipolar I major depression generally lasts longer than minor depression, and the duration of multiple episodes within an individual varies. However, the probability of recovery over time from an episode of major depression appears to decline with each successive episode. PMID:23561241

    Full Text Available In 1975 Fieve and Dunner made the distinction between hypomania and mania as hypomania does not usually cause social and occupational impair-ment and hospitalization is not needed, moreover patients do not experience psychosis. Bipolar disorder type I is defined by the presence of manic and depressive episodes and differs from Bipolar disorder type II characterized with hipomanic and depressive episodes. Bipolar disorder type I and II do not differ in their depressive episodes. It is still point of contention whether bipolar type II is a variant of bipolar disorder type I or is positioned on the spectrum between bipolar type I and unipolar disorder. Even there are some similarities in characteristics of depressive episodes and outcome features of different bipolar disorder subtypes, there are differences that can be useful in differential diagnosis and treatment. This paper aims to focus on those differences between bipolar disorder type I and II.

    Full Text Available Abstract Background Within the context of a biopsychosocial model of the treatment of depressive episodes, a multidisciplinary approach is needed. Clinical pathways have been developed and implemented in hospitals to support multidisciplinary teamwork. The aim of this study is to explore current practice for the treatment of depressive episodes in Flemish psychiatric hospitals. Current practice in different hospitals is studied to get an idea of the similarities (outlined as a pathway and the differences in the treatment of depressive episodes. Methods A convenience sample of 11 Flemish psychiatric hospitals participated in this qualitative study. Semi-structured interviews were conducted with different types of health care professionals (n = 43. The websites of the hospitals were searched for information on their approach to treating depressive episodes. Results A flow chart was made including the identified stages of the pathway: pre-admission, admission (observation and treatment, discharge and follow-up care. The characteristics of each stage are described. Although the stages are identified in all hospitals, differences between hospitals on various levels of the pathway exist. Hospitals emphasized the individual approach of each patient. The results point to a biopsychosocial approach to treating depressive episodes. Conclusion This study outlined current practice as a pathway for Flemish inpatients with depressive episodes. Within the context of surveillance of quality and quantity of care, this study may encourage hospitals to consider developing clinical pathways.

    Full Text Available INTRODUCTION: Personality traits have been associated with primary depression. However, it is not known whether this association takes place in the case of depression comorbid with fibromyalgia. OBJECTIVE: The authors investigated the association between a current major depressive episode and temperament traits (e.g., harm avoidance. METHOD: A sample of 69 adult female patients with fibromyalgia was assessed with the Temperament and Character Inventory. Psychiatric diagnoses were assessed with the Mini-International Neuropsychiatric Interview severity of depressive symptomatology with the Beck Depression Inventory, and anxiety symptomatology with the IDATE-state and pain intensity with a visual analog scale. RESULTS: A current major depressive episode was diagnosed in 28 (40.5% of the patients. They presented higher levels of harm avoidance and lower levels of cooperativeness and self-directedness compared with non-depressed patients, which is consistent with the Temperament and Character Inventory profile of subjects with primary depression. However, in contrast to previous results in primary depression, no association between a major depressive episode and self-transcendence was found. CONCLUSIONS: The results highlight specific features of depression in fibromyalgia subjects and may prove important for enhancing the diagnosis and prognosis of depression in fibromyalgia patients.

    In major depressive disorder, depressive episodes reoccur in ∼60% of cases; however, neural mechanisms of depressive relapse are poorly understood. Depressive episodes are characterized by aberrant topology of the brain's intrinsic functional connectivity network, and the number of episodes is one of the most important predictors for depressive relapse. In this study we hypothesized that specific changes of the topology of intrinsic connectivity interact with the course of episodes in recurrent depressive disorder. To address this hypothesis, we investigated which changes of connectivity topology are associated with the number of episodes in patients, independently of current symptoms and disease duration. Fifty subjects were recruited including 25 depressive patients (two to 10 episodes) and 25 gender- and age-matched control subjects. Resting-state functional magnetic resonance imaging, Harvard-Oxford brain atlas, wavelet-transformation of atlas-shaped regional time-series, and their pairwise Pearson's correlation were used to define individual connectivity matrices. Matrices were analysed by graph-based methods, resulting in outcome measures that were used as surrogates of intrinsic network topology. Topological scores were subsequently compared across groups, and, for patients only, related with the number of depressive episodes and current symptoms by partial correlation analysis. Concerning the whole brain connectivity network of patients, small-world topology was preserved but global efficiency was reduced and global betweenness-centrality increased. Aberrant nodal efficiency and centrality of regional connectivity was found in the dorsal striatum, inferior frontal and orbitofrontal cortex as well as in the occipital and somatosensory cortex. Inferior frontal changes were associated with current symptoms, whereas aberrant right putamen network topology was associated with the number of episodes. Results were controlled for effects of total grey matter

    A major depressive episode diagnosed according to DSM-IV criteria can be accompanied by symptoms that DSM-IV does not include. These symptoms are sometimes classified as comorbidities. Our study assessed altered behavioral modes during a major depressive episode; ie, if 1 or more modes of behavior operated less or even not at all ("never"), or if the operation of others was more frequent or even constant ("always"). We hypothesize that these altered behavioral modes, especially the extreme positions "never" (hypomodes) and "always" (hypermodes) might correlate with depression scores and thus represent a typical symptom of depression. We used the 35-item Salzburg Subjective Behavioral Analysis (SSBA) questionnaire to measure altered behavioral modes in 63 depressed patients and 87 non-depressed controls. Depression was assessed using the Hamilton Depression Scale. In our test group (n=63) we found a total of 888 extreme positions. The mean number of extreme positions per patient was 11.15±5.173 (SD). Extreme positions were found in all 35 behavioral modes. The mean Hamilton score was 22.08±7.35 (SD). The association of the incidence of extreme positions and the Hamilton score in our test group was highly significant (Spearman's Rho=0.41; p=.001). In the control group (n=87), only 11 persons were found to display extreme positions, with a total of only 25. Although this study has several limitations, such as the small sample or the use of a questionnaire in the validation procedure, the significant correlation of extreme positions and the Hamilton score indicate that altered modes of behavior as detected with the SSBA might be typical symptoms in a major depressive episode.

    Hopelessness depression (HD) is a subtype of depression postulated by the Hopelessness Theory of Depression to present as a constellation of symptoms occurring when an individual with a specific cognitive vulnerability (negative inferential style) experiences negative life events. In the current study, the course of HD episodes was evaluated prospectively and analyzed to explore patterns of symptom onset and remission. In 169 HD episodes reported by 65 participants, survival analyses were conducted on the time to onset or remission for 29 individual symptoms. Survival analyses yielded probability density graphs for risk of onset and risk of offset that indicated whether the symptom tended to appear or remit early, late, or unpredictably during the episode. The symptom of hopelessness often appeared earliest in HD episodes, followed by self-blame, brooding/worry, decreased self-esteem, dependency, and decreased appetite. Hopelessness, decreased self-esteem, self-blame, brooding/worry, dependency, and increased appetite were typically the latest symptoms to remit. The current study provided evidence for patterns of symptom onset and remission in HD episodes. Hopelessness and other symptoms predicted to appear according to the Hopelessness Theory were generally the earliest to appear, latest to remit, and appeared to form the core syndrome of these HD episodes. Identifying patterns of symptom onset and remission may provide a tool for subtyping depression episodes. Clinically, these results point to the utility of attending to patterns of symptom onset and remission in patients presenting with HD episodes, particularly for treatment planning and monitoring. © 2013 Wiley Periodicals, Inc.

    Major depressive disorder (MDD) has been associated with increased pituitary gland volume (PGV), which is thought to reflect stress-related dysregulation related to hypothalamic-pituitary-adrenal (HPA) axis activity. However, it is unclear whether PGV alteration reflects a "dynamic" change related to current mood instability or if it is a stable marker of illness vulnerability. In this study we investigated PGV in currently depressed patients (cMDD) (n=31), remitted depressed patients (rMDD) (n=31) and healthy controls (n=33), using 1.5 Tesla magnetic resonance imaging (MRI). The groups were matched for age and gender. We found no significant PGV, intra-cranial volume (ICV) or whole brain volume (WBV) differences between cMDD patients, rMDD patients and healthy controls. Furthermore, PGV was not correlated with clinical features of depression (e.g., age of onset; number of episodes; and scores on subscales of the Beck Depression Inventory, the Positive Affect and Negative Affect Scale, and the Mood and Anxiety Symptom Questionnaire). In conclusion, PGV does not appear to be a marker of current or past MDD in adult patients.

    Little is known about factors that predict first lifetime episodes of major depression in middle-aged women. It is not known whether health-related factors and life stress pose more or less of a risk to the onset of clinical depression than does the menopausal transition. The Structured Clinical Interview for DSM-IV Axis I Disorders (SCID) was used to assess diagnoses of lifetime, annual and current major depression in a community-based sample of premenopausal or early perimenopausal African American and White women. Menstrual cycle characteristics, psychosocial and health-related factors, and blood samples for assay of reproductive hormones were obtained annually. Two hundred and sixty-six women without a history of major depression at baseline constituted the cohort for the current analyses. Over 7 years of follow-up, 42 (15.8%) women met criteria for a diagnosis of major depression. Frequent vasomotor symptoms (VMS; hot flashes and/or night sweats) (HR 2.14, p=0.03) were a significant predictor of major depression in univariate analyses. After simultaneous adjustment for multiple predictors in Cox proportional hazards analyses, frequent VMS were no longer significant; lifetime history of an anxiety disorder (HR 2.20, p=0.02) and role limitations due to physical health (HR 1.88, p=0.07) at baseline and a very stressful life event (HR 2.25, p=0.04) prior to depression onset predicted a first episode of major depression. Both earlier (e.g. history of anxiety disorders) and more proximal factors (e.g. life stress) may be more important than VMS in contributing to a first episode of major depression during midlife.

    Full Text Available Background: Anomalous self-experiences (ASEs aggregate in schizophrenia spectrum disorders, but the relationship between ASEs, and depression has been studied to a limited extent. Lower self-esteem has been shown to be associated with depression in early psychosis. Our hypothesis is that ASEs in early phases of schizophrenia are linked to lower levels of self-esteem, which in turn is associated with depression. Aim: The aim is to examine the relationship between ASEs, self-esteem and depression in first-episode schizophrenia spectrum disorders.Method: ASEs were assessed in 55 patients with first-episode schizophrenia by means of the Examination of anomalous Self-Experience (EASE instrument. Assessment of depression was based on the Calgary Depression Scale for Schizophrenia (CDSS. Self-esteem was measured using the Rosenberg Self-Esteem Scale (RSES. Symptom severity was assessed using the Structured Clinical Interview for the Positive and Negative Syndrome Scale (SCI-PANSS. Substance misuse was measured with the Drug Use Disorder Identification Test (DUDIT, and alcohol use was measured with the Alcohol Use Disorder Identification Test (AUDIT. Data on childhood adjustment were collected using the Premorbid Adjustment Scale (PAS. Data on childhood trauma were collected using the Norwegian version of the Childhood Trauma Questionnaire, short form (CTQ-SF. Results: Analyses detected a significant association between current depression and ASEs as measured by the EASE in women, but not in men. The effect of ASEs on depression appeared to be mediated by self-esteem. No other characteristics associated with depression influenced the relationship between depression, self-esteem and ASEs. Conclusion: Evaluating ASEs can assist clinicians in understanding patients’ experience of self-esteem and depressive symptoms. The complex interaction between ASEs, self-esteem, depression and suicidality could be a clinical target for the prevention of suicidality

    Panic disorder with or without comorbid agoraphobia (PD/PDA) has been linked to an increased risk to develop subsequent depressive episodes, yet the underlying pathophysiology of these disorders remains poorly understood. We aimed to identify a biomarker panel predictive for the development of a depressive disorder (major depressive disorder and/or dysthymia) within a 2-year-follow-up period. Blood serum concentrations of 165 analytes were evaluated in 120 PD/PDA patients without depressive disorder baseline diagnosis (6-month-recency) in the Netherlands Study of Depression and Anxiety (NESDA). We assessed the predictive performance of serum biomarkers, clinical, and self-report variables using receiver operating characteristics curves (ROC) and the area under the ROC curve (AUC). False-discovery-rate corrected logistic regression model selection of serum analytes and covariates identified an optimal predictive panel comprised of tetranectin and creatine kinase MB along with patient gender and scores from the Inventory of Depressive Symptomatology (IDS) rating scale. Combined, an AUC of 0.87 was reached for identifying the PD/PDA patients who developed a depressive disorder within 2 years (n = 44). The addition of biomarkers represented a significant (p = 0.010) improvement over using gender and IDS alone as predictors (AUC = 0.78). For the first time, we report on a combination of biological serum markers, clinical variables and self-report inventories that can detect PD/PDA patients at increased risk of developing subsequent depressive disorders with good predictive performance in a naturalistic cohort design. After an independent validation our proposed biomarkers could prove useful in the detection of at-risk PD/PDA patients, allowing for early therapeutic interventions and improving clinical outcome.

    The independence or interdependence of grief and major depression has been keenly argued in relation to recent DSM definitions and encouraged the current study. We report a phenomenological study seeking to identify the experiential and phenomenological differences between depression and grief as judged qualitatively by those who had experienced clinical (n=125) or non-clinical depressive states (n=28). Analyses involving the whole sample indicated that, in contrast to grief, depression involved feelings of hopelessness and helplessness, being endless and was associated with a lack of control, having an internal self-focus impacting on self-esteem, being more severe and stressful, being marked by physical symptoms and often lacking a justifiable cause. Grief was distinguished from depression by the individual viewing their experience as natural and to be expected, a consequence of a loss, and with an external focus (i.e. the loss of the other). Some identified differences may have reflected the impact of depressive "type" (e.g. melancholia) rather than depression per se, and argue for a two-tiered model differentiating normative depressive and grief states at their base level and then "clinical" depressive and 'pathological' grief states by their associated clinical features. Comparative analyses between the clinical and non-clinical groups were limited by the latter sub-set being few in number. The provision of definitions may have shaped subjects׳ nominated differentiating features. The study identified a distinct number of phenomenological and clinical differences between grief and depression and few shared features, but more importantly, argued for the development of a two-tiered model defining both base states and clinical expressions.

    Full Text Available Abstract Objective To validate the ICD-10 diagnosis of a single depressive episode as used in daily clinical psychiatric practice and as recorded in the Danish Psychiatric Central Research Register. Methods Patients discharged with a diagnosis of a single depressive episode were consecutively sampled from the register and diagnosed according to an interview using the Schedules for Clinical Assessment in Neuropsychiatry (SCAN. Results A total of 75.4% of 399 patients with a register diagnosis of a single depressive episode also got this diagnosis according to the SCAN interview (82.8% for severe type of a single depression, 76.0% for moderate type of a single depression and 65.2% for mild type of a single depression. Conclusion The ICD-10 diagnosis of a single depressive episode can be used in daily clinical practice with sufficient precision. The validity of the diagnosis is highest for severe and moderate type of depression and decreases for mild depression.

    The aim of this study was to determine the differences in personality traits between individuals with Major Depressive Disorder (MDD) and Bipolar Disorder (BD) during a depressive episode, when it can be hard to differentiate them. Data on personality traits (NEO-FFI), mental disorders (Mini International Neuropsychiatric Interview Plus) and socioeconomic variables were collected from 245 respondents who were in a depressive episode. Individuals with MDD (183) and BD (62) diagnosis were compared concerning personality traits, clinical aspects and socioeconomic variables through bivariate analyses (chi-square and ANOVA) and multivariate analysis (logistic regression). There were no differences in the prevalence of the disorders between socioeconomic and clinical variables. As for the personality traits, only the difference in Agreeableness was statistically significant. Considering the control of suicide risk, gender and anxiety comorbidity in the multivariate analysis, the only variable that remained associated was Agreeableness, with an increase in MDD cases. The brief version of the NEO inventories (NEO-FFI) does not allow for the analysis of personality facets. During a depressive episode, high levels of Agreeableness can indicate that MDD is a more likely diagnosis than BD.

    The hopelessness theory of depression proposes that individuals with a depressogenic cognitive style are more likely to become hopeless and experience depression following negative life events. Although the neurophysiological underpinnings of cognitive style remain speculative, research indicates that decreased relative left frontal brain electrical activity holds promise as a traitlike marker of depression. This begs the question: Do measures of depressogenic cognitive style and resting frontal brain asymmetry index a common vulnerability? The present study provides preliminary support for this hypothesis. At baseline assessment, increased cognitive vulnerability to depression was associated with decreased relative left frontal brain activity at rest in individuals with no prior history of, or current, depression. Following baseline assessment, participants were followed prospectively an average of 3 years with structured diagnostic interviews at 4-month intervals. Both cognitive vulnerability and asymmetric frontal cortical activity prospectively predicted onset of first depressive episode in separate univariate analyses. Furthermore, multivariate analyses indicated that cognitive vulnerability and frontal asymmetry represented shared, rather than independent, predictors of first depression onset.

    • BACKGROUND: A bipolar spectrum definition presented to help the designation of more appropriate diagnostic criteria for the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-V is Ghaemi et al. Bipolar Spectrum Disorder (BSD. The present study evaluates the BSD frequency among inpatients with major depressive disorder (MDD and tries to elucidate the contribution of second degree diagnostic items of BSD in the BSD definition.
    • METHODS: One hundred individuals aged 18-65 with current MDD consecutive admitted in three university affiliated psychiatric center were clinically interviewed. The patients with mental retardation or the history of substance dependence/ abuse were excluded. The interviews were carried out by a trained general practitioner according to an 11-item checklist comprised of criteria C (2 items and D (9 items of Ghaemi et al. BSD.
    • RESULTS: Fifty three males and 47 females entered the study. Patients' mean age was 34.16 ± 9.58. Thirty eight patients (39.2%: 18 males and 20 females met the complete diagnostic criteria of BSD. Early-onset depression (53.0%, recurrent depression (40.0% and treatment resistant depression (38.8% were the most frequent accessory items of BSD, but using logistic regression three items -recurrent major depressive episodes (MDEs, treatment resistant depression, and brief MDE- had the significant weight to predict the BSD. Then, three mentioned items were simultaneously entered the logistic regression model: brif MDE (β = 1.5, EXP (β = 4.52, p = 0.007, treatment resistant depression (β = 1.28, EXP (β = 3.62, p = 0.01, and recurrent MDEs (β = 1.28, EXP (β = 3.62, p = 0.01 had the highest strength in predicting BSD and account for 21-30% of BSD diagnosis variance in sum.

      High fish consumption and omega-3 polyunsaturated fatty acid (PUFA) intake are suggested to benefit mental well-being but the current evidence is conflicting. Our aim was to evaluate whether a higher level of fish consumption, a higher intake of omega-3 PUFAs, and a higher serum concentration of omega-3 PUFAs link to a lower 12-month prevalence of depressive episodes.We used data from the nationwide Health 2000 Survey (n = 5492) and the Fishermen Study on Finnish professional fishermen and their family members (n = 1265). Data were based on questionnaires, interviews, health examinations, and blood samples. Depressive episodes were assessed with the M-CIDI (the Munich version of the Composite International Diagnostic Interview) and a self-report of two CIDI probe questions, respectively. Fish consumption was measured by a food frequency questionnaire (g/day) and independent frequency questions (times/month). Dietary intake (g/day) and serum concentrations (% from fatty acids) of PUFAs were determined. Fish consumption was associated with prevalence of depressive episodes in men but not in women. The prevalence of depressive episodes decreased from 9% to 5% across the quartiles of fish consumption (g/day) in men of the Health 2000 Survey (p for linear trend = 0.01), and from17% to 3% across the quartiles of fish consumption (times/month) in men of the Fishermen Study (p for linear trend = 0.05). This association was modified by lifestyle; in the Health 2000 Survey a higher level of fish consumption was related to a lower prevalence of depressive episodes in men who consumed the most alcohol, were occasional or former smokers, or had intermediate physical activity. The associations between depressive episodes and the intake or serum concentrations of omega-3 PUFAs were not consistent.In men, fish consumption appears as a surrogate for underlying but unidentified lifestyle factors that protect against depression.

      Depressive episodes are typically the initial presentation of bipolar disorder. The evidence as to whether depressive episodes occurring in persons who later convert to bipolar disorder are symptomatically distinct from episodes of unipolar depression remains controversial. As there are crucial differences in the therapeutic management, symptom profiles indicating subsequent bipolar conversion may aid in appropriate treatment. A representative community sample of originally N = 3021 adolescents and young adults aged 14-24 years at baseline was assessed up to four times over 10 years. Assessment of symptoms was conducted by clinically trained interviewers using the standardized M-CIDI. Symptom profiles of depressive episodes were compared via logistic regression between subjects that subsequently developed (hypo-)manic episodes (n = 35) or remained unipolar depressive (n = 659). Initial depression amongst prospective converters was characterized by significantly increased suicidality (odds ratio, OR = 2.31), higher rates of feelings of worthlessness and excessive guilt (OR = 2.52), complete loss of pleasure (OR = 2.53) and diurnal variation (OR = 4.30). No differences were found for hyperphagia, hypersomnia and psychomotor alterations. Findings suggest that the symptom profile of initial depressive episodes may be useful in the identification of subjects with an elevated risk for the subsequent conversion to bipolar disorder. © 2015 John Wiley & Sons A/S.

    • Goethe's anxieties, depressive episodes and (self-)therapeutic strategies: a contribution to method integration in psychotherapy.

      2013-01-01

      In psychiatry and psychotherapy, abstract scientific principles need to be exemplified by narrative case reports to gain practical precision. Goethe was one of the most creative writers, productive scientists, and effective statesmen that ever lived. His descriptions of feelings, emotions, and mental states related to anxieties, depressive episodes, dysthymia, and creativity are unique in their phenomenological precision and richness. His life and work can thus serve as an excellent example enhancing our understanding of the relationship between anxiety, depression and creativity. Furthermore, he described (self-)therapeutic strategies that reinforce and refine modern views. Goethe's self-assessments in his works and letters, and the descriptions by others are analyzed under the perspective of current psychiatric classification. His therapeutic techniques and recommendations are compared with cognitive-behavioral, psychodynamic, and existential psychotherapy to amplify modern concepts of psychotherapy. From a scientific perspective, several distinctive depressive episodes can be diagnosed in Goethe's life. They were characterized by extended depressive moods, lack of drive, and loss of interest and self-esteem combined with social retreat. Goethe displayed diffuse and phobic anxieties as well as dysthymia. His (self-)therapeutic strategies were: (a) the systematic use of helping alliances, (b) behavioral techniques, (c) cognitive reflection on meanings and beliefs, (d) psychodynamic and psychoanalytic remembering, repeating, and working through, and (e) existential striving for self-actualization, social commitment, meaning, and creativity. In Goethe's life, creative incubation, illumination, and elaboration appear to have been associated with psychic instability and dysthymia, sometimes with depressive episodes in a clinical sense. On the one hand, his creative work was triggered by anxieties, dysthymia, and depressive moods. On the other hand, his creativity

    Although depressive symptoms in first episode psychosis have been associated with cannabis abuse, their influence on the long-term functional course of FEP patients who abuse cannabis is unknown. The aims of the study were to examine the influence of subclinical depressive symptoms on the long-term outcome in first episode-psychosis patients who were cannabis users and to assess the influence of these subclinical depressive symptoms on the ability to quit cannabis use. 64 FEP patients who were cannabis users at baseline were followed-up for 5 years.

    The stress generation hypothesis was tested in two different longitudinal studies examining relations between weekly depression symptom ratings and stress levels in adolescents and emerging adults at varied risk for depression. The participants in Study 1 included 240 adolescents who differed with regard to their mothers' history of depressive disorders. Youth were assessed annually across 6 years (Grades 6-12). Consistent with the depression autonomy model, higher numbers of prior major depressive episodes (MDEs) were associated with weaker stress generation effects, such that higher levels of depressive symptoms predicted increases in levels of dependent stressors for adolescents with two or more prior MDEs, but depressive symptoms were not significantly related to dependent stress levels for youth with three or more prior MDEs. In Study 2, the participants were 32 remitted-depressed and 36 never-depressed young adults who completed a psychosocial stress task to determine cortisol reactivity and were reassessed for depression and stress approximately 8 months later. Stress generation effects were moderated by cortisol responses to a laboratory psychosocial stressor, such that individuals with higher cortisol responses exhibited a pattern consistent with the depression autonomy model, whereas individuals with lower cortisol responses showed a pattern more consistent with the depression sensitization model. Finally, comparing across the two samples, stress generation effects were weaker for older participants and for those with more prior MDEs. The complex, multifactorial relation between stress and depression is discussed.

    Full Text Available To investigate the effect of the neighbourhood built environment on trajectories of depression symptom episodes in adults from the general Canadian population.We used 10 years of data collection (2000/01-2010/11 from the Canadian National Population Health Study (n = 7114. Episodes of depression symptoms were identified using the Composite International Diagnostic Interview Short-Form. We assessed the presence of local parks, healthy food stores, fast food restaurants, health services and cultural services using geospatial data. We used latent class growth modelling to identify different trajectories of depression symptom episodes in the sample and tested for the effect of neighbourhood variables on the trajectories over time.We uncovered three distinct trajectories of depression symptom episodes: low prevalence (76.2% of the sample, moderate prevalence (19.2% and high prevalence of depression symptom episodes (2.8%. The presence of any neighbourhood service (healthy food store, fast-food restaurant, health service, except for cultural service was significantly associated with a lower probability of a depression symptom episode for those following a trajectory of low prevalence of depression symptom episodes. The presence of a local park was also a significant protective factor in trajectory groups with both low and moderate prevalence of depression symptom episodes. Neighbourhood characteristics did not significantly affect the trajectory of high prevalence of depression symptom episodes.For individuals following a trajectory of low and moderate prevalence of depression symptom episodes, the neighbourhood built environment was associated with a shift in the trajectory of depression symptom episodes. Future intervention studies are recommended to make policy recommendations.

    The purpose of this work was to study the explanatory models of patients with first episode depression presenting to a tertiary care hospital located in North-western India. One hundred sixty four consecutive patients with diagnosis of first episode depression (except severe depression with psychotic symptoms) according to the International Classification of Diseases-10th Revision (ICD-10) and ≥18 years of age were evaluated for their explanatory models using the causal models section of Explanatory Model Interview Catalogue (EMIC). The most common explanations given were categorized into Karma-deed-heredity category (77.4%), followed by psychological explanations (62.2%), weakness (50%) and social causes (40.2%). Among the various specific causes the commonly reported explanations by at least one-fourth of the sample in decreasing order were: will of god (51.2%), fate/chance (40.9%), weakness of nerves (37.8%), general weakness (34.7%), bad deeds (26.2%), evil eye (24.4%) and family problems (21.9%). There was some influence of sociodemographic features on the explanations given by the patients. From the study, it can be concluded that patients with first episode depression have multiple explanatory models for their symptoms of depression which are slightly different than those reported in previous studies done from other parts of India. Understanding the multiple explanatory models for their symptoms of depression can have important treatment implications. Copyright © 2012 Elsevier B.V. All rights reserved.

    First order theory of mind, as measured by the 'Reading the Mind in the Eyes Test' Revised, is impaired in schizophrenia. However, no study has investigated whether this occurs in first-episode schizophrenia. Also, it is unclear whether such a deficit is specific to schizophrenia, and whether convenience control samples, particularly undergraduate university students, represent valid comparison groups. This study investigated theory of mind ability, measured by the 'Reading the Mind in the Eyes Test' Revised, in a group of first-episode schizophrenia outpatients (n=13) and three control groups: outpatients with non-psychotic major depression (n=14), individuals from the general community (n=16) and from an undergraduate university course (n=27). The schizophrenia group exhibited significant theory of mind impairments compared to both non-psychiatric control groups but not the depression group. Unexpectedly, the depression group was not significantly impaired compared to the community control group, and the university control group exhibited superior theory of mind ability relative to all three groups. The findings indicate theory of mind deficits in first episode schizophrenia and support the implementation of theory of mind interventions in first-episode schizophrenia treatment programs. Results also indicate that community rather than university control groups represent more valid comparison groups in first-episode schizophrenia research.

    Previous studies have shown that overgeneral autobiographical memory (OGM) is a characteristic of depression. However, there are no studies to explore the association between baseline OGM and depressive symptoms at follow-up in patients with first-episode depression (FE). This study investigated whether baseline OGM predicts depressive symptoms at follow-up in patients with FE. We recruited 125 patients with FE. The participants were divided into remitted group and non-remitted group according to the severity of their depression at 12 months follow-up. The measures consisted of the 17-item Hamilton Depression Rating Scale, Ruminative Response Scale, and Autobiographical Memory Test. Hierarchical linear regression analyses and bootstrap mediation analyses were conducted. The results showed that non-remitted patients had more OGM at baseline. Baseline OGM predicted depressive symptoms at follow-up in patients with FE. Rumination mediated the relationship between baseline OGM and depressive symptoms at follow-up. Our findings highlight OGM as a vulnerability factor involved in the maintenance of depression in patients with FE.

    The present study examined if any patient characteristics at baseline predicted depressive symptoms at 10 years and whether patients prone to depressive symptoms in the first year of treatment had a different prognosis in the following years. A total of 299 first-episode psychosis (FEP) patients with schizophrenia spectrum disorders were assessed for depressive symptoms with PANSS depression item (g6) at baseline, and 1, 2, 5 and 10 years of follow up. At 10 years, depressive symptoms were also assessed with Calgary Depression Scale for Schizophrenia (CDSS). A PANSS g6 ≥ 4 and CDSS score ≥ 6 were used as a cut-off score for depression. A total of 122 (41%) patients were scored as depressed at baseline, 75 (28%) at 1 year, 50 (20%) at 2 years, 33 (16%) at 5 years, and 35 (19%) at 10 years of follow up. Poor childhood social functioning and alcohol use at baseline predicted depression at 10 years of follow up. Thirty-eight patients were depressed at both baseline and 1 year follow up. This group had poorer symptomatic and functional outcome in the follow-up period compared to a group of patients with no depression in the first year of treatment. Depressive symptoms are frequent among FEP patients at baseline but decrease after treatment because their general symptoms have been initiated. Patients with poor social functioning in childhood and alcohol use at baseline are more prone to have depressive symptoms at 10 years of follow up. Patients struggling with depressive symptoms in the first year of treatment should be identified as having poorer long-term prognosis. © 2014 Wiley Publishing Asia Pty Ltd.

    Although social anxiety disorder (SAD) is strongly associated with the subsequent development of a depressive disorder (major depressive disorder or dysthymia), no underlying biological risk factors are known. We aimed to identify biomarkers which predict depressive episodes in SAD patients over a 2-year follow-up period. One hundred sixty-five multiplexed immunoassay analytes were investigated in blood serum of 143 SAD patients without co-morbid depressive disorders, recruited within the Netherlands Study of Depression and Anxiety (NESDA). Predictive performance of identified biomarkers, clinical variables and self-report inventories was assessed using receiver operating characteristics curves (ROC) and represented by the area under the ROC curve (AUC). Stepwise logistic regression resulted in the selection of four serum analytes (AXL receptor tyrosine kinase, vascular cell adhesion molecule 1, vitronectin, collagen IV) and four additional variables (Inventory of Depressive Symptomatology, Beck Anxiety Inventory somatic subscale, depressive disorder lifetime diagnosis, BMI) as optimal set of patient parameters. When combined, an AUC of 0.86 was achieved for the identification of SAD individuals who later developed a depressive disorder. Throughout our analyses, biomarkers yielded superior discriminative performance compared to clinical variables and self-report inventories alone. We report the discovery of a serum marker panel with good predictive performance to identify SAD individuals prone to develop subsequent depressive episodes in a naturalistic cohort design. Furthermore, we emphasise the importance to combine biological markers, clinical variables and self-report inventories for disease course predictions in psychiatry. Following replication in independent cohorts, validated biomarkers could help to identify SAD patients at risk of developing a depressive disorder, thus facilitating early intervention.

    Depression is a common comorbidity of chronic obstructive pulmonary disease (COPD) and is associated with increased exacerbations, healthcare utilization, and mortality. Among Medicare beneficiaries newly diagnosed with COPD, the objectives of this study were to (1) estimate the rate of new episodes of depression and (2) identify factors associated with depression. We identified beneficiaries with a first diagnosis of COPD during 2006-2012 using a 5% random sample of Medicare administrative claims data by searching for ICD-9-CM codes 490, 491.x, 492.x, 494.x, or 496. We identified episodes of depression using ICD-9-CM codes 296.2x, 296.3x, and 311.xx. We calculated incidence rates and their 95% confidence intervals (95% CI) and used a discrete time analysis to identify factors associated with development of depression. Between 2006 and 2012, 125,348 beneficiaries meeting inclusion criteria were newly diagnosed with COPD. Twenty-three percent developed depression following COPD diagnosis. The annualized incidence rate of depression per 100 beneficiaries following COPD diagnosis was 9.4 (95% CI 9.3, 9.5). Rates were highest in the first 2 months following COPD diagnosis. COPD diagnosis was associated with increased risk of depression (risk ratio 1.76; 95% CI 1.73, 1.79) as were COPD-related hospitalizations (risk ratio 4.59; 95% CI 4.09, 5.15), a measure of COPD severity. Diagnosis of COPD increases the risk of depression. This study will aid in the allocation of resources to monitor and provide support for individuals with COPD at high risk of developing depression.

    Background Although depressive symptoms in first episode psychosis have been associated with cannabis abuse, their influence on the long-term functional course of FEP patients who abuse cannabis is unknown. The aims of the study were to examine the influence of subclinical depressive symptoms on the long-term outcome in first episode-psychosis patients who were cannabis users and to assess the influence of these subclinical depressive symptoms on the ability to quit cannabis use. Methods 64 FEP patients who were cannabis users at baseline were followed-up for 5 years. Two groups were defined: (a) patients with subclinical depressive symptoms at least once during follow-up (DPG), and (b) patients without subclinical depressive symptoms during follow-up (NDPG). Psychotic symptoms were measured using the Positive and Negative Syndrome Scale (PANSS), depressive symptoms using the Hamilton Depression Rating Scale (HDRS)-17, and psychosocial functioning was assessed using the Global Assessment of Functioning (GAF). A linear mixed-effects model was used to analyze the combined influence of cannabis use and subclinical depressive symptomatology on the clinical outcome. Results Subclinical depressive symptoms were associated with continued abuse of cannabis during follow-up (β= 4.45; 95% confidence interval [CI]: 1.78 to 11.17; P = .001) and with worse functioning (β = -5.50; 95% CI: -9.02 to -0.33; P = .009). Conclusions Subclinical depressive symptoms and continued cannabis abuse during follow-up could be predictors of negative outcomes in FEP patients. PMID:25875862

He had a diagnosis of intra­cranial germinoma, and the atypical MDE symptoms subsided after the operation. However, he had a relapse of atypical MDE 7 months after the first surgery. His mood and binge eating symptoms subsided, but intractable body weight gain only partially improved after treatment. When encountering manifestations of depression with atypical features, especially with binge eating symptoms in male children and adolescents, with early onset age, no family history, and prolonged depressive episodes, clinicians should consider not only mood disorders including bipolar spectrum disorders but also organic brain lesions such as intracranial germinoma.

    Full Text Available Computational neuroanatomical techniques that are used to evaluate the structural correlates of disorders in the brain typically measure regional differences in gray matter or white matter, or measure regional differences in the deformation fields required to warp individual datasets to a standard space. Our aim in this study was to combine measurements of regional tissue composition and of deformations in order to characterize a particular brain disorder (here, major depressive disorder. We use structural Magnetic Resonance Imaging (MRI data from young adults in a first episode of depression, and from an age- and sex-matched group of non-depressed individuals, and create population gray matter (GM and white matter (WM tissue average templates using DARTEL groupwise registration. We obtained GM and WM tissue maps in the template space, along with the deformation fields required to co-register the DARTEL template and the GM and WM maps in the population. These three features, reflecting tissue composition and shape of the brain, were used within a joint independent-components analysis (jICA to extract spatially independent joint sources and their corresponding modulation profiles. Coefficients of the modulation profiles were used to capture differences between depressed and non-depressed groups. The combination of hippocampal shape deformations and local composition of tissue (but neither shape nor local composition of tissue alone was shown to discriminate reliably between individuals in a first episode of depression and healthy controls, suggesting that brain structural differences between depressed and non-depressed individuals do not simply reflect chronicity of the disorder but are there from the very outset.

    To assess the clinical validity of individual DSM-IV criteria for hypomania. In an international sample of 5,635 patients with major depressive episodes (Bridge Study), DSM-IV criteria for hypomania (stem questions, number and quality of symptoms, duration and exclusion criteria) were systematically assessed and their validity analysed on the basis of clinical data including family history, course, and other clinical characteristics. Three stem questions for hypomania, irritability, elevated mood and the added question of increased activity, showed comparable validity. The results support the current DSM-IV requirement for a higher symptom threshold (4 of 7 hypomanic symptoms) in cases of irritable mood. Longer durations of hypomanic episodes were associated with higher scores on all validators. The results did not support the DSM-IV durational requirements for hypomanic episodes (4 days) and manic episodes (7 days). Brief hypomanic episodes of 1, 2 or 3 days were valid and would meet validity criteria for inclusion. The three exclusion criteria in DSM-IV (hypomania due to the use of antidepressants or of other substances, or to other medical conditions) were found to exclude patients with bipolar depression and should therefore not be retained. These results support several revisions of the DSM-IV concept of hypomanic episodes: specifically, the inclusion of increased activity as a gate question, the inclusion of 1 or 2 to 3-day episodes and the elimination of all exclusion criteria.

    Prospective data on depressive symptoms and blood pressure (BP) are scarce, and the impact of age on this association is poorly understood. The present study examines longitudinal trajectories of depressive episodes and the probability of hypertension associated with these trajectories over time. Participants were 6,889 men and 3,413 women London based civil servants, aged 35–55 years at baseline, followed for 24 years between 1985 and 2009. Depressive episode (defined as scoring 4 or more on the General Health Questionnaire-Depression subscale or using prescribed antidepressant medication) and hypertension (systolic/diastolic blood pressure ≥ 140/90 mm Hg or use of antihypertensive medication) were assessed concurrently at five medical examinations. In the fully adjusted longitudinal logistic regression analyses based on Generalized-Estimating-Equations using age as the time scale, participants in the “increasing depression” group had a 24% (p<0.05) lower risk of hypertension at ages 35–39, compared to those in the “low/transient depression” group. However, there was a faster age-related increase in hypertension in the “increasing depression” group, corresponding to a 7% (p<0.01) greater increase in the odds of hypertension for every each five-year increase in age. A higher risk of hypertension in the first group of participants was not evident before age 55. A similar pattern of association was observed in men and women although it was stronger in men. This study suggests that the risk of hypertension increases with repeated experience of depressive episodes over time and becomes evident in later adulthood. PMID:21339474

    The objective of the present study was to assess differences in prevalence of the metabolic syndrome among depressed patients in regard to the duration of the illness (first episode versus recurrent episodes). A total of 190 patients suffering from major depressive disorder were included in the study, diagnosed according to International classification of disorders, 10th revision. The same criteria were used to divide participants into two groups: first episode major depressive disorder and major depressive disorder with recurrent episodes. The metabolic syndrome was defined according to the criteria of the American National Cholesterol Education Program-Treatment Panel III. Results showed that metabolic syndrome is significantly more prevalent in patients with recurrent major depressive disorder (45.2%) compared to patients with first episode of major depressive disorder (27.3%), mainly due to differences in plasma glucose, triglycerides and HDL-cholesterol levels. These findings indicate the importance of the duration of depression and the number of recurring episodes as factors involved in etiopathogenesis of the associated metabolic syndrome.

  7. [Transcranial direct current stimulation for depressive disorders].

    Major depressive disorders are one of the most prevalent psychiatric disorders worldwide but approximately 20-30 % of patients do not respond to standard guideline conform treatment. Recent neuroimaging studies in depressive patients revealed altered activation patterns in prefrontal brain areas and that successful cognitive behavioral therapy and psychopharmacological interventions are associated with a reversal of these neural alterations. Therefore, a direct modulation of prefrontal brain activation by non-invasive brain stimulation techniques, such as transcranial direct current stimulation (tDCS) seems to be a promising and innovative approach for the treatment of depressive disorders. In addition, recent neuropsychological findings indicated an augmentation of positive tDCS effects by simultaneous external activation of the stimulated brain area, for example by cognitive training tasks. Based on these findings, the possibility to augment cognitive-emotional learning processes during cognitive behavioral therapy by simultaneous tDCS to increase antidepressive therapeutic effects is discussed in this article.

    Altered nitric oxide (NO) signaling has been associated with the pathophysiology of Bipolar Disorder (BD), directly affecting neurotransmitter release and synaptic plasticity cascades. Lithium has shown to regulate NO levels in preclinical models. However, no study has addressed peripheral NO levels in unmedicated BD. Also, lithium's effects on NO levels have not been studied in humans. Plasma NO was evaluated in subjects with BD I and II during a depressive episode (n = 26). Subjects had a score of ≥18 in the 21-item Hamilton Depression Rating Scale and were followed-up during a 6-week trial with lithium. Plasma NO levels were also compared to matched healthy controls (n = 28). NO was determined by chemiluminescence method. Lithium treatment significantly increased plasma NO levels after 6 weeks of treatment in comparison to baseline levels in bipolar depression (p = 0.016). Baseline NO levels during depressive episodes showed no difference when matching up to healthy controls (p = 0.66). The present findings suggest that lithium upregulates NO signaling in unmedicated BD with short illness duration. Further studies with larger samples are needed to confirm the effects of lithium on NO pathway and its association with synaptic plasticity and therapeutics of BD. Published by Elsevier Ltd.

The aim of this analysis was to explore the relationship between suicidality and AIA symptoms in patients with BD-I experiencing mania with depressive symptoms, using data from a previous naturalistic study.Patients and methods: Psychiatrists completed an online questionnaire about their adult patients who had a current BD-I manic episode. Questions covered the DSM-5 “with mixed features” specifier, the severity of AIA symptoms, the frequency and controllability of suicidal ideation, and the number of suicide attempts.Results: Of 1,035 patients with BD-I mania who were included in the analyses, 348 (33.6% met the criteria for the DSM-5 “with mixed features” specifier (three or more depressive symptoms. These patients were further stratified according to the severity of their AIA symptoms: “mild AIA” (zero or one AIA symptom above a severity threshold; 105 patients or “severe AIA” (all three AIA symptoms above a severity threshold; 167 patients. A greater incidence of suicidal ideation was observed in the severe AIA group (71.9% than in the mild AIA group (47.6%. Twice as many patients had easily controlled suicidal ideation than difficult-to-control suicidal ideation in both subgroups. The mean number of suicide attempts was higher in the severe AIA group than in the mild AIA group, during the current episode (0.84 vs 0.34 attempts, respectively; P<0.05 and over the patient’s lifetime (1.56 vs 1.04 attempts, respectively.Conclusion: The high risk of suicide among BD-I mania patients with depressive

    Mitochondrial dysfunction and energy metabolism impairment are key components in the pathophysiology of bipolar disorder (BD) and may involve a shift from aerobic to anaerobic metabolism. Measurement of brain lactate in vivo using proton magnetic resonance spectroscopy (H-MRS) represents an important tool to evaluate mitochondrial and metabolic dysfunction during mood episodes, as well as to monitor treatment response. To date, very few studies have quantified brain lactate in BD. In addition, no study has longitudinally evaluated lactate using H-MRS during depressive episodes or its association with mood stabilizer therapy. This study aimed to evaluate cingulate cortex (CC) lactate using 3-T H-MRS during acute depressive episodes in BD and the possible effects induced by lithium monotherapy. Twenty medication-free outpatients with short length of BD (80% drug-naive) in a current major depressive episode were matched with control subjects. Patients were treated for 6 weeks with lithium monotherapy at therapeutic doses in an open-label trial (blood level, 0.48 ± 0.19 mmol/L). Cingulate cortex lactate was measured before (week 0) and after lithium therapy (week 6) using H-MRS. Antidepressant efficacy was assessed with the 21-item Hamilton Depression Rating Scale as the primary outcome. Subjects with BD depression showed a significantly higher CC lactate in comparison to control subjects. Furthermore, a significant decrease in CC lactate was observed after 6 weeks of lithium treatment compared with baseline (P = 0.002). CC Lactate levels was associated with family history of mood disorders and plasma lithium levels. This is the first report of increased CC lactate in patients with bipolar depression and lower levels after lithium monotherapy for 6 weeks. These findings indicate a shift to anaerobic metabolism and a role for lactate as a state marker during mood episodes. Energy and redox dysfunction may represent key targets for lithium's therapeutic actions.

    The aim of this study was to determine whether there was any relationship between hippocampal volume, and glucocorticoid regulation, and cognitive dysfunctions in drug-naïve major depressive disorder (MDD) patients during their first episode. Twenty drug-free female MDD patients in their first episode and 15 healthy females as control subjects were included in the study. All subjects underwent 3.0 Tesla (T) magnetic resonance imaging (MRI), comprehensive neuropsychological testing and dexamethasone suppression tests (DST). The volumes of the right and left hippocampus of the patients were found to be significantly smaller than those of the controls. Patients were found to have significantly lower scores on measures of attention, working memory, psychomotor speed, executive functions, and visual and verbal memory fields. The performance of the patients only in the recollection memory and memory of reward-associated rules were positively correlated with hippocampal volumes. The volumes of the left and right hippocampus did not correlate with basal or post-dexamethasone cortisol levels. Our findings indicate that depressed patients have smaller hippocampi even in the earlier phase of their illness. Further research efforts are needed to explain the mechanisms that are responsible for the small hippocampus in depressed patients.

    Mental illness has been observed to follow a neuroprogressive course, commencing with prodrome, then onset, recurrence and finally chronic illness. In bipolar disorder and schizophrenia responsiveness to treatment mirrors these stages of illness progression, with greater response to treatment in the earlier stages of illness and greater treatment resistance in chronic late stage illness. Using data from 5627 participants in 15 controlled trials of duloxetine, comparator arm (paroxetine, venlafaxine, escitalopram) or placebo for the treatment of an acute depressive episode, the relationship between treatment response and number of previous depressive episodes was determined. Data was dichotomised for comparisons between participants who had >3 previous episodes (n=1697) or ≤3 previous episodes (n=3930), and additionally for no previous episodes (n=1381) or at least one previous episode (n=4246). Analyses were conducted by study arm for each clinical trial, and results were then pooled. There was no significant difference between treatment response and number of previous depressive episodes. This unexpected finding suggests that treatments to reduce symptoms of depression during acute illness do not lose efficacy for patients with a longer history of illness.

    Full Text Available BACKGROUND: Pulmonary tuberculosis (TB persists an important contributor to the burden of diseases in developing countries. TB control success is based on the patient's compliance to the treatment. Depressive disorders have been negatively associated with compliance of therapeutic schemes for chronic diseases. This study aimed to estimate the significance and magnitude of major depressive episode as a hazard factor for negative outcomes (NO, including abandon or death in patients receiving TB treatment. METHODOLOGY/PRINCIPAL FINDINGS: A longitudinal study was conducted to evaluate the association of major depressive episode (MDE, as measured by a 5-item version of the Center for Epidemiological Studies Depression Scale (CES-D with NO to TB treatment. Patients with confirmed TB were enrolled before the start of TB treatment. Baseline measurements included socio-demographic variables as well as the CES-D, which was also applied every month until the end of the treatment. Death and treatment default were assessed monthly. Survivor function (SF for NO according to MDE status (CES-D≥6 at baseline (MDEb was estimated. Cox's Regression was performed for bivariate analyses as well as for the multivariate model. A total of 325 patients accepted to participate in the study, of which 34 where excluded for diagnosis of MDR-TB. NO was observed in 24 patients (8.2%; 109 (37% presented MDEb. Statistically significant difference was found on the SF of patients with and without MDEb (0.85 vs. 0.96, p-value = 0.002. The hazard ratio for NO, controlled for age, sex, marital status and instruction level was 3.54 (95%CI 1.43-8.75; p-value = 0.006. CONCLUSION: The presence of MDE at baseline is associated to NO of TB treatment. Targeting detection and treatment of MDE may improve TB treatment outcomes.

    Depressive symptoms are frequently seen in patients with dementia and mild cognitive impairment (MCI). Evidence suggests that there may be a link between current depressive symptoms and Alzheimer disease (AD)-associated pathological changes, such as an increase in cortical amyloid-β (Aβ). However, limited in vivo studies have explored the relationship between current depressive symptoms and cortical Aβ in patients with MCI and AD. Our study, using a large sample of 455 patients with MCI and 153 patients with AD from the Alzheimer's disease Neuroimaging Initiatives, investigated whether current depressive symptoms are related to cortical Aβ deposition. Depressive symptoms were assessed using the Geriatric Depression Scale and Neuropsychiatric Inventory-depression/dysphoria. Cortical Aβ was quantified using positron emission tomography with the Aβ probe(18)F-florbetapir (AV-45).(18)F-florbetapir standardized uptake value ratio (AV-45 SUVR) from the frontal, cingulate, parietal, and temporal regions was estimated. A global AV-45 SUVR, defined as the average of frontal, cingulate, precuneus, and parietal cortex, was also used. We observed that current depressive symptoms were not related to cortical Aβ, after controlling for potential confounds, including history of major depression. We also observed that there was no difference in cortical Aβ between matched participants with high and low depressive symptoms, as well as no difference between matched participants with the presence and absence of depressive symptoms. The association between depression and cortical Aβ deposition does not exist, but the relationship is highly influenced by stressful events in the past, such as previous depressive episodes, and complex interactions of different pathways underlying both depression and dementia.

    Full Text Available OBJECTIVE: We describe the prevalence of depressive and bipolar spectrum episodes in fathers in antenatal and postnatal periods, as well as at 12 months after childbirth. METHOD: A longitudinal follow-up study was conducted with a representative sample of 739 fathers whose children were born between April 2007 and May 2008 in maternity wards in the city of Pelotas, southern Brazil. Paternal psychopathology was measured with the Mini Neuropsychiatric Interview (MINI across three time points: between 28 and 34 weeks of pregnancy (T1, 30 to 60 days postpartum (T2, and 12 months after childbirth (T3. RESULTS: The prevalence of depressive episodes was 5.0% at T1, 4.5% at T2, and 4.3% at T3. Mixed episodes were present in 3%, 1.7%, and 0.9% of subjects, respectively, and accounted for 61.1% of the cases of depression in the antenatal period, 37.5% in postpartum, and 21.4% at 12 months. Depressive and manic/hypomanic episodes were significantly associated during pregnancy and in postpartum, but not at 12 months after childbirth. CONCLUSION: Bipolar episodes were common in men with depressive symptoms during their partner's pregnancy in the postpartum period and, to a lesser extent, 12 months after childbirth. Therefore, this population should be carefully investigated for manic and hypomanic symptoms.OBJETIVO: Verificar a prevalência dos episódios depressivos e bipolares em homens no período pré e pós-natal, assim como 12 meses após o parto.

    Oxidative stress may play an important role in the pathophysiology of major depressive disorder (MDD). The aim of this study was to investigate the serum levels of oxidative stress biomarkers and S100B in patients with MDD in an acute phase, and evaluate the changes in superoxide dismutase (SOD), protein carbonyl content (PCC), glutathione peroxidase (GPX), 8-hydroxy 2'-deoxyguanosine after treatment (8-OHdG), catalase (CAT), thiobarbituric acid reactive substances (TBARS) and S100B. We consecutively enrolled 21 MDD inpatients in an acute phase and 40 healthy subjects. Serum oxidative stress markers were measured with assay kits. Serum SOD and CAT activities in MDD patients in an acute phase were significantly higher than those of healthy subjects, and serum PCC levels were significantly lower. The HAM-D scores had a significantly positive association with S100B levels. Eighteen depressed patients were followed up, and there was no significant difference among all of the markers after treatment. In conclusion, our results suggest that increased activities of both SOD and CAT might be indicators of acute depressive episodes in MDD patients.

    The primary aim of the study was to test (1) how metacognition relates to the concept of mindful attention awareness, and (2) whether metacognitions or mindful attention awareness best predicted symptoms of depression. Data was collected from three samples: currently depressed (n = 37), previously depressed (n = 81) and never depressed controls (n = 50). There was a moderate correlation between mindful attention awareness and three of five metacognitive subscales. Both mindful attention awareness and metacognition were significantly correlated with depression severity scores after controlling for anxiety. The depressed group had significantly more dysfunctional metacognitions and less mindful attention awareness than the never depressed group. Negative beliefs about worry and mindful attention awareness were also significantly different in the previously depressed group compared with the never depressed. This suggests that metacognitions and mindful attention awareness can be vulnerability factors for depression. The results also indicated that anxiety symptoms and negative beliefs about worry were the most important factors in predicting depression. In conclusion, the study shows that metacognitions and mindful attention awareness are two related but separate constructs and that metacognitions emerged as the best predictor of depression. These results provide support for the metacognitive model of emotional disorders. Copyright © 2015 John Wiley & Sons, Ltd.

    This study compared cortisol responses to a standardized psychosocial stressor during a major depressive episode (MDE) and again during remission in adolescents and young adults. Twenty-six individuals with no personal or family history of a major psychiatric disorder (NC) and 24 individuals with a diagnosis of major depressive disorder (MDD) at Time 1 participated in the study. The MDD group showed robust cortisol responses during their index episode and after recovery. In contrast, the NC group showed habituation to the repeated psychosocial stressor, as evident in a flatter cortisol response profile at Time 2. Within the MDD group, net peak cortisol during the first stress test was positively associated with the duration of the index MDE and negatively associated with the total duration of all MDEs. Whereas summary indices of cortisol responses were relatively stable across repeated stress tasks within the MDD group, this was not the case for NC. Results demonstrate that cortisol responses fail to habituate to repeated psychosocial stress during recovery from an MDE and could reflect a trait-like marker of risk for recurrence.

    Prior research has found that humiliating marital events are associated with depression. Building on this research, the current study investigated the association between one specific humiliating marital event-discovering that one's partner had an affair-and past-year major depressive episode (MDE) in a probability sample of married or cohabiting men and women who were at high risk for depression based on the criterion that they scored below the midpoint on a measure of marital satisfaction (N = 227). Results indicate that (i) women were more likely than men to report discovering their partner had an affair in the prior 12 months; (ii) discovering a partner affair was associated with a higher prevalence of past-year MDE and a lower level of marital adjustment; and (iii) the association between discovering a partner affair and MDE remained statistically significant when holding constant demographic variables and marital adjustment. These results support continued investigation into the impact that finding out about an affair has on the mental health of the person discovering a partner affair. © 2015 Family Process Institute.

  5. Disturbances in Hypothalamic-Pituitary-Adrenal Axis and Immunological Activity Differentiating between Unipolar and Bipolar Depressive Episodes.

    Full Text Available Differentiating bipolar depression (BD from unipolar depression (UD is difficult in clinical practice and, consequently, accurate recognition of BD can take as long as nine years. Research has therefore focused on the discriminatory capacities of biomarkers, such as markers of the hypothalamic-pituitary-adrenal (HPA axis or immunological activity. However, no previous study included assessments of both systems, which is problematic as they may influence each other. Therefore, this study aimed to explore whether cortisol indicators and inflammatory markers were a independently associated with and/or b showed effect modification in relation to a lifetime (hypomanic episode in a large sample of depressed patients.Data were derived from the Netherlands Study of Depression and Anxiety and comprised 764 patients with a DSM-IV depressive disorder at baseline, of which 124 (16.2% had a lifetime (hypomanic episode at the 2-year assessment, or a more recent episode at the 4-year or 6-year assessment. Baseline cortisol awakening response, evening cortisol and diurnal cortisol slope were considered as cortisol indicators, while baseline C-reactive Protein (CRP, Interleukin-6 (IL-6, and Tumor Necrosis Factor Alpha (TNF-α were included as inflammatory markers.In depressed men and women, none of the cortisol indicators and inflammatory markers were (independently associated with a (hypomanic episode. However, effect modification was found of diurnal cortisol slope and CRP in relation to a (hypomanic episode. Further analyses showed that depressed men with high levels of diurnal cortisol slope and CRP had an increased odds (OR=10.99, p=.001 of having a (hypomanic episode. No significant differences were found in women.Our findings suggest that the combination of high diurnal cortisol slope and high CRP may differentiate between UD and BD. This stresses the importance of considering HPA-axis and immunological activity simultaneously, but more research is needed

    Depressive symptoms are common in the elderly and they have been associated with cognitive and functional impairment. However, relatively less is known about the relationship of a lifetime history of depression to cognitive impairment and functional status. The aim of this cross-sectional study was to assess whether current depressive symptoms and past depression are associated with cognitive or functional impairment in a community-based sample representative of east Sydney, Australia. We also examined whether there was an interaction between current and past depression in their effects on cognitive performance. Eight hundred non-demented aged participants received a neuropsychological assessment, a past psychiatric history interview and the 15-item Geriatric Depression Scale. The Bayer-Activities of Daily Living scale was completed by an informant to determine functional ability. Clinically relevant depressive symptoms were present in 6.1% of the sample and 16.6% reported a history of depression. Participants with current depression had significantly higher levels of psychological distress and anxiety, and lower life satisfaction and performed worse on memory and executive function compared to participants without current depression. After controlling for anxiety the effect on executive function was no longer significant while the effect on memory remained significant. A history of depression was associated with worse executive function, higher levels of psychological distress and anxiety, and lower life satisfaction. After controlling for psychological distress the effect of past depression on executive function was no longer significant. There were no significant interactions between current and past depression in their effects on cognitive performance. There were no differences between participants with or without current depression and with or without past depression on functional abilities. These results support the view that current and past depressive

    Depression is one of the most common mental disorders worldwide. There are a number of depression subtypes, and there has been much debate about how to most accurately capture and organize the features and subtypes of major depression. We review the current state of categorizing unipolar major depression with psychotic features (psychotic major depression, PMD), including clinical, biological, and treatment aspects of the disorder. We then propose some improvements to the current unipolar major depression categorization system. Finally, we identify important issues in need of further research to help elucidate the subtype of unipolar PMD. PMID:17548842

    Following efforts made in recent years to provide effective mental health treatments based on evidence-based guidelines, a working definition was developed in the literature detailing a minimum level of "adequate mental health care" for serious mental illness. However, little is known about racial or ethnic disparities in receipt of adequate mental health care for individuals affected with serious mental illness. The objective of this study was to examine disparities among Caucasian and Hispanic youths in receipt of adequate mental health care for past-year major depressive episodes. Data for this study were drawn from the 2005 National Survey on Drug Use and Health. The study sample was composed of 1,169 Caucasian youths and 316 Hispanic youths aged 12 to 17 with past-year major depressive episodes. The percentages of youths in the sample who received adequate mental health care for past-year major depressive episodes were estimated, and the correlates of receipt of adequate mental health care were examined. Thirty-four percent of the full sample received adequate mental health care for past-year major depressive episodes, but separate analyses indicated that adequate mental health care was received by a significantly higher proportion of Caucasian youths (36%) than Hispanic youths (27%). The odds of receiving adequate mental health care for past-year major depressive episodes for Caucasians were 1.55 times that of Hispanics (p=.01). Having Medicaid or coverage via the State Children's Health Insurance Program significantly increased the odds of receiving adequate mental care for past-year major depressive episodes for both Hispanics and Caucasians. As mental health problems of adolescents from diverse racial or ethnic backgrounds become more easily identified and a larger proportion of these groups is referred to mental health treatment services, it is important to examine the degree to which treatment should be tailored to engage and retain specific racial or

    highlight present aspects related to its practice. METHOD: We reviewed in the literature studies on efficacy, symptom remission, predictive response factors as well as current aspects regarding quality of life, the patients' perception, mechanism of action, technique and cognitive impairment. RESULTS: The main results found in the this revision were: 1 electroconvulsive therapy is more effective than any antidepressant medication; 2 the remission of depression with electroconvulsive therapy varies, in general, from 50 to 80%; 3 The effect of electroconvulsive therapy in brain-derived neurotrophic factor levels is still controversial; 4 electroconvulsive therapy has a positive effect in the improvement of quality of life; 5 patients submitted to electroconvulsive therapy have, in general, a positive perception about the treatment. CONCLUSION: Electroconvulsive therapy remains a highly efficacious treatment in treatment-resistant depression. With the improvement of its technique, electroconvulsive therapy has become an even safer and more useful procedure both for the acute phase and for the prevention of new depressive episodes.

    Objective To investigate the differences of personality characteristics between schizophrenia with positive symptoms and bipolar disorder, current episode manic or depression with psychotic symptoms by MMPI, which can provide clues to their differential diagnosis. Methods Twenty-four schizophrenia patients with positive symptoms and thirty-seven bipolar disorder patients, current episode manic or depression with psychotic symptoms were enrolled in this study. Subjects were tested personality with MMPI software, and then calculated the scores of ten clinical scales. All data analyses were performed using SPSS for Windows software, version 13.0, to find the differences between the two groups. Results The male schizophrenia with positive symptoms patients' social introversion(Si) score was significantly higher than female schizophrenia patients(t=2.186, P=0.040). There was no significant difference between the genders in bipolar disorder patients. No significant differences of the clinical scales were found between the two patient groups(P>0.05), however, the scores of psychopathic deviate, paranoia, schizophrenia and hypomania in schizophrenia patients with positive symptoms were higher than the T score of China norm, as well as the score of paranoia in bipolar disorder patients. Conclusions Personality characteristics changes exist in both schizophrenia with positive symptoms and bipolar disorder patients when compared with China norm, there is no significant difference between the two patient groups, social introversion in schizophrenia patients with positive symptoms may have gender differences.%目的:探讨阳性症状为主型精神分裂症和伴有精神病性症状的躁狂或抑郁的双相障碍患者的个性特征,为其鉴别诊断提供线索。方法采用MMPI测试软件,评估24例精神分裂症阳性症状为主型患者(精神分裂症组)和37例伴有精神病性症状的躁狂或抑郁的双相障碍患者(双相障碍组)人格

    Psychotic disorders are associated with a significant impairment in occupational functioning that can begin in the prodromal phase of the disorder. As a result, individuals with a psychotic disorder may not maintain their social class at birth. The aim of this study was to examine the distribution of the social classes of individuals presenting with a first episode of psychosis (FEP) compared to the general population and to their family of origin. We evaluated whether social drift was associated with depression, hopelessness and suicidality at first presentation. All individuals with a FEP presenting to a community mental health service between 1995 and 1999 and to an early intervention service between 2005 and 2011were included. Diagnosis was established using the Structured Clinical Interview for DSM IV diagnoses and clinical evaluations included the Calgary Depression Scale for Schizophrenia, Beck Hopelessness Scale and the Suicidal Intent Scale. 330 individuals were included in the study and by the time of presentation, individuals with a FEP were more likely to be represented in the lower social classes compared to the general population. 43% experienced a social drift and this was associated with a diagnosis of a non-affective disorder, co-morbid cannabis abuse and a longer DUP. Individuals who did not experience a social drift had a higher risk of hopelessness. Social drift is common in psychotic disorders; however, individuals who either maintain their social class or experience upward social class mobility are more susceptible to hopelessness.

    This paper introduces a "blue pyjama syndrome" (whereby wearing hospital pyjamas results in an exaggerated impression of severity). We performed a 5-day, prospective, randomized, cross-over study in a French mood disorder unit for inpatients. At Day 1 (D1) and Day 5 (D5), two 5-minute video interviews were recorded with patients in pyjamas or in day clothes (the sequence was randomly allocated). Psychiatrists unaware of the study objective assessed the videos and scored their clinical global impressions (CGI, with scores ranging from 1 to 7). Of 30 participants with major depressive episode selected for inclusion, 26 participants (69% women) provided useable data for an evaluation by 10 psychiatrists. Pyjamas significantly increased the psychiatrists' CGI ratings of disease severity by 0·65 [0·27; 1·02] points. The psychiatrists' global impressions also rated patients as significantly less severe at D5 in comparison with D1 by -0·66 [-1·03; -0·29] points. The "blue pyjama syndrome" is in the same order of magnitude as the difference observed after a week of hospitalisation. This potentially calls into question the reliability and validity of observer ratings of depression.

    Full Text Available Abstract Background Major depression is one of the leading causes of disability worldwide, yet epidemiologic data are not available for many countries, particularly low- to middle-income countries. In this paper, we present data on the prevalence, impairment and demographic correlates of depression from 18 high and low- to middle-income countries in the World Mental Health Survey Initiative. Methods Major depressive episodes (MDE as defined by the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DMS-IV were evaluated in face-to-face interviews using the World Health Organization Composite International Diagnostic Interview (CIDI. Data from 18 countries were analyzed in this report (n = 89,037. All countries surveyed representative, population-based samples of adults. Results The average lifetime and 12-month prevalence estimates of DSM-IV MDE were 14.6% and 5.5% in the ten high-income and 11.1% and 5.9% in the eight low- to middle-income countries. The average age of onset ascertained retrospectively was 25.7 in the high-income and 24.0 in low- to middle-income countries. Functional impairment was associated with recency of MDE. The female: male ratio was about 2:1. In high-income countries, younger age was associated with higher 12-month prevalence; by contrast, in several low- to middle-income countries, older age was associated with greater likelihood of MDE. The strongest demographic correlate in high-income countries was being separated from a partner, and in low- to middle-income countries, was being divorced or widowed. Conclusions MDE is a significant public-health concern across all regions of the world and is strongly linked to social conditions. Future research is needed to investigate the combination of demographic risk factors that are most strongly associated with MDE in the specific countries included in the WMH.

    The aim of this study was to compare hair thyroid hormone (TH) levels among first-episode patients with major depressive disorder (F-MDD), recurrent patients with major depressive disorder (R-MDD) and healthy controls (HC). The Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA) were used to evaluate the clinical symptoms of patients. Electrochemiluminescence immunoassay was used to measure the hair TH levels. We compared the differences in hair TH levels among F-MDD patients, R-MDD patients, and HC. Before the disease episode, hair T3 levels differed significantly between F-MDD patients and HC. In the disease episode, hair T3 levels differed significantly between F-MDD or R-MDD patients and HC; and hair T4 levels differed significantly between R-MDD patients and HC. Hair T3 levels significantly negative correlated with HAMD scores in F-MDD patients. Our findings suggested that disease duration of recurring episodes of depression may influence hair TH levels. © 2015 Wiley Publishing Asia Pty Ltd.

    The objective of this study was to examine the associations between compulsive buying and substance dependence/abuse, major depressive episodes, and generalized anxiety disorder at the mean age of 43. Participants came from a community-based random sample of residents in 2 New York counties in 1975 (N = 548). The participants were followed from adolescence to early midlife. The mean age of participants at the most recent interview was 43.0 (standard deviation = 2.8). Of the participants, 55% were females. Over 90% of the participants were Caucasian. The prevalence of substance dependence/abuse, major depressive episodes, and generalized anxiety disorder (during the past 5 years before the interviews) was 6.6, 13.7, and 11.5%, respectively. Logistic regression analyses showed that compulsive buying was significantly associated with substance dependence/abuse (adjusted odds ratio = 1.60), major depressive episodes (adjusted odds ratio = 1.70), and generalized anxiety disorder (adjusted odds ratio = 1.63), despite controlling for substance dependence/abuse, major depressive episodes, and generalized anxiety disorder, respectively, at the mean age of 37, and demographic factors. Since the study sample is limited to predominantly Caucasian participants (over 90%) with a close association to a small geographic area, the findings may not be generalizable to racial/ethnic minority groups or individuals living in other parts of the country. Nevertheless, it is important that clinicians treating substance dependence/abuse, major depressive episodes, and generalized anxiety disorder consider the role of compulsive buying.

    Major depressive episode (MDE) is one of the most common psychiatric diagnoses and it has long-term mental and physiological consequences. The status of cognitive functions is of specific importance in case of affective disorders, due to their influence not only on patients' behaviour, but to a certain extent also on the success of psychotherapy. In addition, examining the impact of mood and affective disorders on cognitive functions also helps us understand the relationship between brain plasticity and neurocognitive networks. While the relationship between explicit, conscious memory and mood are relatively well-explored, the effect of mood and affective disorders on working memory and implicit sequence learning received less attention. The present review aims to overview available results in these less-explored areas. Research suggests that while working memory performance shows impairments in MDE and in some specific mood conditions, effects of affective disorders and mood on implicit sequence learning are more contradictory, highlighting the need for further studies in this field.

  2. A point mutation associated with episodic ataxia 6 increases glutamate transporter anion currents.

    Episodic ataxia is a human genetic disease characterized by paroxysmal cerebellar incoordination. There are several genetically and clinically distinct forms of this disease, and one of them, episodic ataxia type 6, is caused by mutations in the gene encoding a glial glutamate transporter, the excitatory amino acid transporter-1. So far, reduced glutamate uptake by mutant excitatory amino acid transporter-1 has been thought to be the main pathophysiological process in episodic ataxia type 6. However, excitatory amino acid transporter-1 does not only mediate secondary-active glutamate transport, but also functions as an ion channel. Here, we examined the effects of a disease-associated point mutation, P290R, on glutamate transport, anion current as well as on the subcellular distribution of excitatory amino acid transporter-1 using heterologous expression in mammalian cells. P290R reduces the number of excitatory amino acid transporter-1 in the surface membrane and impairs excitatory amino acid transporter-1-mediated glutamate uptake. Cells expressing P290R excitatory amino acid transporter-1 exhibit larger anion currents than wild-type cells in the absence as well as in the presence of external l-glutamate, despite a lower number of mutant transporters in the surface membrane. Noise analysis revealed unaltered unitary current amplitudes, indicating that P290R modifies opening and closing, and not anion permeation through mutant excitatory amino acid transporter-1 anion channels. These findings identify gain-of-function of excitatory amino acid transporter anion conduction as a pathological process in episodic ataxia. Episodic ataxia type 6 represents the first human disease found to be associated with altered function of excitatory amino acid transporter anion channels and illustrates possible physiological and pathophysiological impacts of this functional mode of this class of glutamate transporters.

    Several lines of evidence show that the immune system is implicated in the pathophysiology of major depressive disorder (MDD) and that treatment with antidepressants affects cytokine and C-reactive protein (CRP) levels. Few studies have investigated immune markers during non-pharmacological treatment. In this follow-up study, we investigated whether CRP and elevated plasma cytokine levels observed before treatment of an acute episode of MDD are normalized during non-pharmacological treatment. We obtained clinical assessments and blood for CRP and cytokine analysis from 50 unmedicated MDD patients, and cytokine levels from healthy controls. The patients received 'therapy as usual' for 12 weeks, and the assessments were then repeated. Of the 43 completers, 29 patients did not receive medication. In the patients receiving treatment without antidepressants, the depressive symptoms and the plasma levels of eight cytokines (interleukin (IL)-1Ra, IL-5,-6,-8,-10, G-CSF, IFN-γ, and TNF-α) were significantly reduced (P = 0.002-0.048). The cytokine levels were no longer different from the controls. The plasma CRP level did not change. Cytokine plasma levels normalized during recovery from an acute depressive episode in MDD without antidepressant treatment. These findings may have implications for the understanding of the role of the immune system in depression and recovery from depression. © 2016 John Wiley & Sons A/S.

  7. 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.

    Olfactory deficits have been reported in major depressive disorder (MDD). However, it remains largely unknown whether MDD is associated with abnormalities in olfactory sulcus morphology, a potential marker of olfactory system development. This magnetic resonance imaging study investigated the length and depth of the olfactory sulcus in 29 currently depressed patients, 27 remitted depressed patients, and 33 age- and gender-matched healthy control subjects. Both current and remitted MDD patients had significantly shallower olfactory sulci bilaterally as compared with controls. Only for male subjects, the right olfactory sulcus was significantly shorter in remitted MDD patients than in controls. The right sulcus depth was negatively correlated with number of depressive episodes in the entire MDD group and with residual depressive symptoms in the remitted MDD group. Medication status, presence of melancholia, and comorbidity with anxiety disorders did not affect the sulcus morphology. These findings suggest that abnormality of the olfactory sulcus morphology, especially its depth, may be a trait-related marker of vulnerability to major depression.

    2010-03-01

    Full Text Available Background and Objectives: Prior research suggests that marital dissatisfaction is associated with Major Depression (MD. The purpose of this study was to investigate whether remission from a first episode of MD is associated with improvement in marital dissatisfaction and whether the degree of marital dissatisfaction at the time of diagnosis has an influence on the outcome of MD. Methods: The Hamilton Rating Scale for Depression, the Dyadic Adjustment Scale and the Areas of Change Questionnaire were administered to 59 married couples in which one member fulfilled DSM-IV criteria for a first Episode of MD, but her husband (or his wife did not suffer any mental disorder, and to 53 control couples at 6 outpatient clinics, at baseline and after a 6-months follow-up. Results: The level of marital dissatisfaction in couples with a persistent depressed participant decreased in comparison to couples without a depressed subject (p < 0.05 CI: -10.6 and -0.2, but there were no significant differences between couples in which the depressed spouse recovered from MD and comparison couples. Regardless of MD´s severity, high levels of satisfaction were associated with a higher probability to recover. Limitations: The follow-up period was short and we assessed the level of marital dissatisfaction using self-report measures. Conclusion: This study shows that MD has an influence on Marital Satisfaction even at a very early stage of the Depressive Disorder. What is more, changes in any of the two factors (MD or marital dissatisfaction influenced the other factor´s course; thus an effective intervention on MD may have a positive impact on marital dissatisfaction as well.

    Full Text Available Abstract Background This study was designed to evaluate the psychiatrists' level of recognition of somatic symptoms associated to a major depressive episode (MDE (DSM-IV-TR criteria and the impact of those somatic symptoms on the treatment effectiveness. Methods This non-interventional study was conducted in 25 medical offices in Puerto Rico from February to December 2003. It had 2 visits separated by 8 weeks. The level of recognition was determined by: the correlation between the physician clinical evaluation and their patients' self-evaluations through different validated instruments using kappa statistics. Chi-square test was used to evaluate the impact of somatic symptoms on treatment antidepressants' effectiveness. Results All the 145 recruited patients reported the presence of at least one somatic symptom associated with their current MDE. In the two visits covered by the study, a fair agreement between the psychiatrists' and the patients' reports was noted for headache, abdominal pain and upper limb pains (0.4003 ≤ κ ≥ 0.6594. For other painful symptoms and painless somatic symptoms, the Kappa values obtained were non-significant. Slight but significant reductions in depression and painful symptoms severity were observed after 8 weeks of treatment. A proportional relationship between the pain and depression severity was observed (p Conclusion The study results show that somatic symptoms: are very common in depressed Puerto Rican patients; are significant under-reported by psychiatrists; and have a significant impact on the antidepressant effectiveness.

    The purpose of this study was to compare escitalopram, problem-solving therapy, and placebo to prevent poststroke depression during 6 months after discontinuation of treatment. We examined for depression 33 patients assigned to placebo, 34 to escitalopram, and 41 to problem-solving therapy. After controlling for age, gender, prior mood disorder, and severity of stroke, new-onset major depression and Hamilton Depression scores were significantly higher 6 months after escitalopram was discontinued compared with the problem-solving therapy or placebo groups. Discontinuation of escitalopram may increase poststroke depressive symptoms.

    The hopelessness theory of depression proposes that individuals with a depressogenic cognitive style are more likely to become hopeless and experience depression following negative life events. Although the neurophysiological underpinnings of cognitive style remain speculative, research indicates that decreased relative left-frontal brain electrical activity holds promise as a trait-like marker of depression. This begs the question: do measures of depressogenic cognitive style and resting fro...

    Introduction. Depressive symptoms are common in schizophrenia and are associated with poorer functioning, lower quality of life, and an elevated risk of suicidal behaviour. There are few studies on the occurrence and correlates of these symptoms in acutely ill patients with schizophrenia. Method. 72 acutely ill patients with schizophrenia were assessed for depression using the Calgary Depression Scale for Schizophrenia (CDSS). A cut-off score of ≥6 on the CDSS was used to identify clinically significant depressive symptoms. The relationship between depression and illness variables, including psychotic symptom dimensions as measured by the Positive and Negative Syndrome Scale for Schizophrenia (PANSS), was examined. Results. Eleven (15.3%) patients had clinically significant depressive symptoms. These patients scored higher on the positive and general psychopathology scales of the PANSS and had higher rates of suicidal behavior and poorer functioning. The severity of depressive symptoms was positively correlated with the PANSS positive subscale and negatively correlated with the PANSS negative subscale. Discussion. These findings confirm previous reports that depressive symptoms in active schizophrenia is related to the severity of positive psychotic symptoms and is a risk factor for suicidal behaviour in these patients.

    Although blockade of dopamine re-uptake and the resulting elevation of excitatory agonists is commonly thought the primary mechanism of cocaine-induced seizures, it is possible that other neurotransmitters such as gamma-aminobutyric acid (GABA) are involved. To examine this possibility, the effects of cocaine on the whole cell GABA current (IGABA) of freshly isolated rat hippocampal neurons were investigated with the patch-clamp technique. Preincubation or acute application of cocaine reversibly suppressed IGABA. The IC50 was 127 microM when cocaine was applied before the application of GABA. The concentration-response relations of cocaine in various GABA concentrations revealed that cocaine inhibited IGABA non-competitively. This effect of cocaine appeared to be independent of voltage. The present study suggests that the GABA receptor/channel complex is also a target for cocaine's action. The suppression of IGABA may contribute to cocaine-induced seizures.

    In depression, non-remission, recurrence of depressive episodes after remission and conversion to bipolar disorder are crucial determinants of poor outcome. The present study aimed to determine the cumulative incidences and clinical predictors of these long-term outcomes after the first lifetime episode of depression. A total of 301 in- or out-patients aged 18-70 years with a validated diagnosis of a single depressive episode were assessed from 2005 to 2007. At 5 years of follow-up, 262 patients were reassessed by means of the life chart method and diagnostic interviews from 2011 to 2013. Cumulative incidences and the influence of clinical variables on the rates of remission, recurrence and conversion to bipolar disorder, respectively, were estimated by survival analysis techniques. Within 5 years, 83.3% obtained remission, 31.5% experienced recurrence of depression and 8.6% converted to bipolar disorder (6.3% within the first 2 years). Non-remission increased with younger age, co-morbid anxiety and suicidal ideations. Recurrence increased with severity and treatment resistance of the first depression, and conversion to bipolar disorder with treatment resistance, a family history of affective disorder and co-morbid alcohol or drug abuse. The identified clinical characteristics of the first lifetime episode of depression should guide patients and clinicians for long-term individualized tailored treatment.

  2. Transcranial Direct Current Stimulation: Considerations for Research in Adolescent Depression

    Full Text Available Adolescent depression is a prevalent disorder with substantial morbidity and mortality. Current treatment interventions do not target relevant pathophysiology and are frequently ineffective, thereby leading to a substantial burden for individuals, families, and society. During adolescence, the prefrontal cortex undergoes extensive structural and functional changes. Recent work suggests that frontolimbic development in depressed adolescents is delayed or aberrant. The judicious application of non-invasive brain stimulation techniques to the prefrontal cortex may present a promising opportunity for durable interventions in adolescent depression. Transcranial direct current stimulation (tDCS applies a low-intensity, continuous current that alters cortical excitability. While this modality does not elicit action potentials, it is thought to manipulate neuronal activity and neuroplasticity. Specifically, tDCS may modulate N-methyl-d-aspartate receptors and L-type voltage-gated calcium channels and effect changes through long-term potentiation or long-term depression-like mechanisms. This mini-review considers the neurobiological rationale for developing tDCS protocols in adolescent depression, reviews existing work in adult mood disorders, surveys the existing tDCS literature in adolescent populations, reviews safety studies, and discusses distinct ethical considerations in work with adolescents.

Methods: This is a multicenter, cross-sectional, observational study. Patients who had originally been diagnosed with MDD, were treated with an antidepressant for 12 weeks for that episode, and achieved either PR or CR at study entry were enrolled in the study. Using the 17-item Hamilton Rating Scale for Depression (HAM-D17, PR was defined as a score of ≥8 and ≤18 and CR as a score of ≤7. Residual symptoms were assessed using the Brief Pain Inventory-Short Form (BPI-SF and the HAM-D17.Results: A total of 323 patients (CR =158, PR =165 were included in the study. Patients in the PR group had a higher mean (standard deviation score in the HAM-D17 than those in the CR group (11.8 [3.1] and 4.4 [2.0], respectively. BPI-SF results showed that “at least moderate PPS” (score ≥3 on BPI-SF question 5 was significantly more prevalent among patients with PR than those with CR (37.0% vs 16.5%, respectively; odds ratio =3.04; P<0.001. Presence of pain (any severity was also more prevalent among patients with PR than those with CR (54.5% vs 35.4%, respectively. The HAM-D17 results for individual items indicated that impaired work and activities, depressed mood, psychological and somatic anxiety, and general somatic symptoms were observed in at least 75% of patients with PR.Conclusion: PR was associated with a higher prevalence of at least moderate PPS

    In times of modern surgery, transplantation and percutaneous techniques, pyogenic liver abscess (PLA) has essentially become a problem of biliary or iatrogenic origin. In the current scenario, diagnostic approach, clinical behavior and therapeutic outcomes have not been profoundly studied. This study analyzes the clinical and microbiological features, diagnostic methods, therapeutic management and predictive factors for recurrence and mortality of first episodes of PLA. A retrospective single-center study was conducted including 142 patients admitted to the Hospital Italiano de Buenos Aires, between 2005 and 2015 with first episodes of PLA. Prevailing identifiable causes were biliary diseases (47.9%) followed by non-biliary percutaneous procedures (NBIPLA, 15.5%). Seventeen patients (12%) were liver recipients. Eleven patients (7.8%) died and 18 patients (13.7%) had recurrence in the first year of follow up. The isolation of multiresistant organisms (p = 0.041) and a history of cholangitis (p 5 mg/dL (p = 0.022) and bilateral involvement (p = 0.014) in the multivariate analysis. NBPLA and PLA after transplantation may be increasing among the population of PLA in referral centers. History of cholangitis is a strong predictor for recurrence.

    Background Genetic and environmental factors shape life-long vulnerability to depression, but most gene–environment interaction (G×E) research has focused on cross-sectional assessments rather than life-course phenotypes. This study tests the hypothesis that the G×E involving the length polymorphism in the serotonin-transporter-gene-linked-promoter-region (5-HTTLPR) and childhood maltreatment is specific to depression that runs a persistent course in adulthood. Methods The hypothesis is tested in two cohorts. Men and women in the Dunedin Study (N=847), New Zealand, followed to age 32 years with 96% retention and women in the E-Risk Study (N=930), England, followed to age 40 years with 96% retention. Diagnoses of past-year major depressive episode were established at four separate assessments. Depression diagnosed on two or more occasions was considered persistent. Results In both cohorts, statistical tests of gene–environment interactions showed positive results for persistent depression but not single-episode depression. Individuals with two short 5-HTTLPR alleles and childhood maltreatment had elevated risk of persistent but not single-episode depression. Limitations Some cases of recurrent depression may have been misclassified as single-episode due to non-contiguous assessment windows, but this would have a conservative effect on the findings. Chronic and recurrent depression could not be reliably distinguished due to non-contiguous periods of assessment. Therefore, the term persistent depression is used to describe either chronic or recurrent course. Conclusions The specific effect on persistent depression increases the significance of this G×E for public health. Research that does not distinguish persistent course may underestimate G×E effects and account for some replication failures in G×E research. PMID:21439648

    Few studies comprehensively evaluate which types of life stress are most strongly associated with depressive episode onsets, over and above other forms of stress, and comparisons between acute and chronic stress are particularly lacking. Past research implicates major (moderate to severe) stressful life events (SLEs), and to a lesser extent, interpersonal forms of stress; research conflicts on whether dependent or independent SLEs are more potent, but theory favors dependent SLEs. The present study used 5 years of annual diagnostic and life stress interviews of chronic stress and SLEs from 2 separate samples (Sample 1 N = 432; Sample 2 N = 146) transitioning into emerging adulthood; 1 sample also collected early adversity interviews. Multivariate analyses simultaneously examined multiple forms of life stress to test hypotheses that all major SLEs, then particularly interpersonal forms of stress, and then dependent SLEs would contribute unique variance to major depressive episode (MDE) onsets. Person-month survival analysis consistently implicated chronic interpersonal stress and major interpersonal SLEs as statistically unique predictors of risk for MDE onset. In addition, follow-up analyses demonstrated temporal precedence for chronic stress; tested differences by gender; showed that recent chronic stress mediates the relationship between adolescent adversity and later MDE onsets; and revealed interactions of several forms of stress with socioeconomic status (SES). Specifically, as SES declined, there was an increasing role for noninterpersonal chronic stress and noninterpersonal major SLEs, coupled with a decreasing role for interpersonal chronic stress. Implications for future etiological research were discussed.

    Background: The aim of this study was to investigate resting-state functional connectivity alteration of the right dorsolateral prefrontal cortex (DLPFC) in patients with first-episode major depressive disorder (MDD). Methods: Twenty-two first-episode MDD patients and thirty age-, gender- and education-matched healthy control subjects were enrolled. Rest state functional magnetic resonance images and structure magnetic resonance images were scanned. The functional connectivity analysis was done based on the result of voxel-based morphometry (VBM). And the right DLPFC was chosen as the seed region of interests (ROI), as its gray matter density (GMD) decreased in the MDD patients compared with controls and its GMD values were negative correlation with the Hamilton Depression Rating Scale (HDRS) scores. Results: Compared to healthy controls, the MDD patients showed increased functional connectivity with right the DLPFC in the left dorsal anterior cingulate cortex (ACC), left parahippocampal gyrus (PHG), thalamus and precentral gyrus. In contrast, there were decreased functional connectivity between the right DLPFC and right parietal lobe. Conclusions: By applying the VBM results to the functional connectivity analysis, the study suggested that abnormality of GMD in right DLPFC might be related to the functional connectivity alteration in the pathophysiology of MDD, which might be useful in further characterizing structure–function relations in this disorder.

    Forty-six individuals with different histories of major depressive episodes (MDEs) completed the Rorschach (Exner, 2003 ) and the Dysfunctional Attitude Scale (DAS; Weissman & Beck, 1978) at 2 assessment points (T1, T2) over a 9-year follow-up. At T1, history of MDE and the Rorschach variable MOR (associated with negative self-image) emerged as significant predictors of number of MDEs over the follow-up. At T2, Rorschach markers of depressive vulnerability and scars were identified (i.e., WSum6, related to illogical thinking; X+%, related to conventional perception and social adjustment; X-%, linked to erroneous judgments; MQ-, associated with impaired social relations; and MOR). Test-retest analyses displayed significant temporal stability in Rorschach variables, with r ranging from .34 to .67 and in the DAS, r = .42. Our findings highlight MDE as a recurrent and serious disorder, number of MDEs as a risk factor for future depressions, and Rorschach variables as markers of depressive vulnerability and scars.

    Prior studies have examined critical expressed emotion (EE-Crit) in mothers in the intergenerational transmission of depression. However, the potential moderating effect of maternal depression diagnostic status in relation to EE-Crit and youth depressive symptoms has yet to be determined. A total of N=121 biological mother/daughter dyads that differed in maternal depression diagnostic status were recruited for the present study: (1) currently depressed mothers (current depression, n=29); (2) formerly depressed mothers (past depression, n=39); and (3) mothers free from any psychiatric history (healthy controls, n=53). Mothers were administered structured clinical interviews and completed self-report measures of EE-Crit and psychopathology, and daughters self-reported depressive symptoms. Results indicated no significant group differences in EE-Crit; however, current maternal depression status moderated EE-Crit such that the magnitude of the relation between EE-Crit and adolescent depressive symptoms was significantly greater in daughters of currently depressed mothers. These findings highlight the importance of considering current maternal depression, rather than a history of maternal depression, in relation to EE-Crit and adolescent depressive symptoms, providing impetus for future investigations.

    Depression is an important cause of morbidity and disability in the world; however, it is under-diagnosed at all care levels. The purpose here is to present recommendations based on the evidence gathered to answer a series of clinical questions concerning risk factors, screening, suicide risk diagnosis and evaluation in patients undergoing a depressive episode and recurrent depressive disorder. Emphasis has been made upon the approach used at the primary care level so as to grant adult diagnosed patients the health care guidelines based on the best and more updated evidence available thus achieving minimum quality standards. A practical clinical guide was elaborated according to standards of the Methodological Guide of the Ministry of Social Protection. Recommendation from guides NICE90 and CANMAT were adopted and updated so as to answer the questions posed while de novo questions were developed. Recommendations 1-22 corresponding to screening, suicide risk and depression diagnosis were presented. The corresponding degree of recommendation is included.

    There is ample evidence that depression is000  a common comorbid health issue in people with type 1 or type 2 diabetes. Reviews have also concluded that depression in diabetes is associated with higher HbA1c levels, less optimal self-care behaviours, lower quality of life, incident vascular...... complications and higher mortality rates. However, longitudinal studies into the course of depression in people with type 1 diabetes remain scarce. In this issue of Diabetologia, Kampling and colleagues (doi: 10.1007/s00125-016-4123-0 ) report the 5 year trajectories of depression in adults with newly diagnosed...... type 1 diabetes (mean age, 28 years). Their baseline results showed that shortly after the diagnosis of type 1 diabetes a major depressive episode was diagnosed in approximately 6% of participants, while 8% suffered from an anxiety disorder. The longitudinal depression data showed that, in a 5 year...

    Expressed emotion (EE), especially criticism, is an important predictor of outcomes for the patient for a wide range of mental health problems. To understand complex links between EE and various relevant variables in early phase psychosis, this study examined criticism, distress of caregivers, other patients', and caregivers' variables, and links between criticism and these variables in those with at-risk mental state (ARMS) for psychosis and first-episode psychosis (FEP). The participants were 56 patients (mean age 18.8 ± 4.2 years) with ARMS and their caregivers (49.4 ± 5.8 years) and 43 patients (21.7 ± 5.2 years) with FEP and their caregivers (49.3 ± 7.4 years). We investigated criticisms made by caregivers using the Japanese version of the Family Attitude Scale and caregiver depressive symptoms via the self-report Beck Depression Inventory. We also assessed psychiatric symptoms and functioning of the patients. Approximately one-third of caregivers of patients with ARMS or FEP had depressive symptoms, predominately with mild-to-moderate symptom levels, whereas only a small portion exhibited high criticism. The level of criticism and depression were comparable between ARMS and FEP caregivers. The link between criticism, caregivers' depression, and patients' symptoms were observed in FEP but not in ARMS caregivers. These findings imply that the interaction between criticism and caregivers' and patients' mental states may develop during or after the onset of established psychosis and interventions for the caregivers should be tailored to the patient's specific stage of illness. Interventions for FEP caregivers should target their emotional distress and include education about patient's general symptoms.

    Previous MRI studies confirmed abnormalities in the limbic-cortical-striatal-pallidal-thalamic (LCSPT) network or limbic-cortico-striatal-thalamic-cortical (LCSTC) circuits in patients with major depressive disorder (MDD), but few studies have investigated the subcortical structural abnormalities. Therefore, we sought to determine whether focal subcortical grey matter (GM) changes might be present in MDD at an early stage. We recruited 30 first episode, untreated patients with major depressive disorder (MDD) and 26 healthy control subjects. Voxel-based morphometry was used to evaluate cortical grey matter changes, and automated volumetric and shape analyses were used to assess volume and shape changes of the subcortical GM structures, respectively. In addition, probabilistic tractography methods were used to demonstrate the relationship between the subcortical and the cortical GM. Compared to healthy controls, MDD patients had significant volume reductions in the bilateral putamen and left thalamus (FWE-corrected, p putamen, and on the dorsal and ventral aspects of left thalamus in MDD patients (FWE-corrected, p putamen and left thalamus have connections with the frontal and temporal lobes, which were found to be related to major depression. Our results suggested that structural abnormalities in the putamen and thalamus might be present in the early stages of MDD, which support the role of subcortical structure in the pathophysiology of MDD. Meanwhile, the present study showed that these subcortical structural abnormalities might be the potential trait markers of MDD.

    Full Text Available Background: The impact of remittances on health problems like depression among immigrants is understudied. Yet immigrants may be particularly emotionally vulnerable to the strains and benefits of providing remittances. Objective: This study examines the association between sending remittances and major depressive episode (MDE and sadness among legal immigrants in the United States. Methods: Cross-sectional data (N=8,236 adults come from the New Immigrant Survey (2003-2004, a representative sample of new U.S. permanent residents. Results: In logistic regression models, immigrants who remitted had a higher risk of MDE and sadness compared to those who did not, net of sociodemographic and health factors. For remitters (N=1,470, the amount of money was not significantly linked to MDE but was associated with a higher risk of sadness among refugees/asylees compared to employment migrants. Conclusions: Among socioeconomically vulnerable migrants such as refugees/asylees, sending remittances may threaten mental health by creating financial hardship. Initiatives that encourage economic stability for migrants may protect against depression.

    The use of antidepressants in treatment of depression in course of bipolar disorders (BD) is controversial. In case of no improvement during monotherapy with mood stabilizer, the use of antidepressants is often necessary. The safety of this group (in context of phase change, mixed states and rapid cycling) is essential and is the subject of many research. In the paper, the authors review the literature concerning efficacy and safety of use of antidepressants in the treatment of affective disorders and long-term impact on the course of the disease. Selection of articles have been made by searching the Medline and Pubmed databases using keywords: antidepressant drugs, bipolar depression, bipolar disorder, efficacy, safety, mania, hypomania. The risk of mania is greater in bipolar disorder type I, than in type II or during treatment with Tricyclic antidepressants (TCAs) and treatment with venlafaxine. The use of SSRIs and bupropion is associated with a relatively small increase of phase change risk. There are different opinions concerning recommended duration of antidepressant treatment. Generally antidepressant use should end after 2-3 months of remission, the risk of recurrence of depression after discontinuation of antidepressants is, however, higher than in case of continuation. In BD type II or BD spectrum, antidepressant monotherapy is allowed in severe depression. In bipolar disorder type I and in case of phase change after antidepressants use in the past, use of antidepressants should be very cautious. Antidepressants are contraindicated in rapid cycling and in mixed episodes. Further work is needed to evaluate the efficacy and safety of antidepressants use.

    Full Text Available Abstract Background The effects of putative risk factors on the onset and/or persistence of depression remain unclear. We aim to develop comprehensive models to predict the onset and persistence of episodes of depression in primary care. Here we explain the general methodology of the predictD-Spain study and evaluate the reliability of the questionnaires used. Methods This is a prospective cohort study. A systematic random sample of general practice attendees aged 18 to 75 has been recruited in seven Spanish provinces. Depression is being measured with the CIDI at baseline, and at 6, 12, 24 and 36 months. A set of individual, environmental, genetic, professional and organizational risk factors are to be assessed at each follow-up point. In a separate reliability study, a proportional random sample of 401 participants completed the test-retest (251 researcher-administered and 150 self-administered between October 2005 and February 2006. We have also checked 118,398 items for data entry from a random sample of 480 patients stratified by province. Results All items and questionnaires had good test-retest reliability for both methods of administration, except for the use of recreational drugs over the previous six months. Cronbach's alphas were good and their factorial analyses coherent for the three scales evaluated (social support from family and friends, dissatisfaction with paid work, and dissatisfaction with unpaid work. There were 191 (0.16% data entry errors. Conclusion The items and questionnaires were reliable and data quality control was excellent. When we eventually obtain our risk index for the onset and persistence of depression, we will be able to determine the individual risk of each patient evaluated in primary health care.

    Major limitations are associated with the use of a single source of information to assess personality pathology. The construct validity of standardized interviews and informant reports on personality pathology has been established relative to other measures of personality pathology, but it is also important to consider these measures in relation to other constructs that should be related to personality pathology. One example is major depression. In this study, we evaluated whether less common...

    Major depression affects multiple physiologic systems. Therefore, analysis of signals that reflect integrated function may be useful in probing dynamical changes in this syndrome. Increasing evidence supports the conceptual framework that complex variability is a marker of healthy, adaptive control mechanisms and that dynamical complexity decreases with aging and disease. We tested the hypothesis that heart rate (HR) dynamics in non-medicated, young to middle-aged males during an acute major ...

  2. First-episode medication-naive major depressive disorder is associated with altered resting brain function in the affective network.

    Directory of Open Access Journals (Sweden)

    Xiaocui Zhang

    Full Text Available BACKGROUND: Major depressive disorder (MDD has been associated with abnormal structure and function of the brain's affective network, including the amygdala and orbitofrontal cortex (OFC. However, it is unclear if alterations of resting-state function in this affective network are present at the initial onset of MDD. AIMS: To examine resting-state function of the brain's affective network in first-episode, medication-naive patients with MDD compared to healthy controls (HCs. METHODS: Resting-state functional magnetic resonance imaging (rs-fMRI was performed on 32 first-episode, medication-naive young adult patients with MDD and 35 matched HCs. The amplitude of low-frequency fluctuations (ALFF of the blood oxygen level-dependent (BOLD signal and amygdala-seeded functional connectivity (FC were investigated. RESULTS: Compared to HC, MDD patients showed reduced ALFF in the bilateral OFC and increased ALFF in the bilateral temporal lobe extending to the insular and left fusiform cortices. Enhanced anti-correlation of activity between the left amygdala seed and the left OFC was found in MDD patients but not in HCs. CONCLUSIONS: Reduced ALFF in the OFC suggests hypo-functioning of emotion regulation in the affective network. Enhanced anti-correlation of activity between the amygdala and OFC may reflect dysfunction of the amygdala-OFC network and additionally represent a pathological process of MDD.

    Cognitive deficits are frequently observed in major depression. Yet, when these deficits emerge and how they relate to the depressed state is unclear. The aim of this 2-part systematic review and meta-analysis is to determine the pattern and extent of cognitive deficits during a first-episode of depression (FED) and their persistence following FED remission. Published, peer-reviewed articles on cognitive function in FED patients through October 2015 were searched. Meta-analyses with random-effects modeling were conducted. Part 1 assessed weighted, mean effect sizes of cognitive function in FED patients relative to healthy controls. Moderator analyses of clinical and demographical variables effects were conducted. Part 2 assessed weighted, mean effect sizes of change in cognitive function at remission compared with acute FED performance in longitudinal studies. Thirty-one studies including 994 FED patients were retained in Part 1. Relative to healthy controls, small to large impairments were observed across most cognitive domains. Remission was associated with a normalization of function in processing speed, learning and memory, autobiographical memory, shifting, and IQ. Lower FED age was associated with higher IQ, but more impairment in word-list delayed memory. Four studies including 92 FED patients were retained in Part 2. Following remission, FED patients showed small improvements in processing speed and shifting but persistent impairment in inhibition and verbal fluency. Significant cognitive deficits are already identifiable during a FED, with some functions showing persistent impairment upon remission. Clinicians must consider cognitive impairment alongside mood symptoms to ensure functional recovery from the FED. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

    Full Text Available Previous MRI studies confirmed abnormalities in the limbic-cortical-striatal-pallidal-thalamic (LCSPT network or limbic-cortico-striatal-thalamic-cortical (LCSTC circuits in patients with major depressive disorder (MDD, but few studies have investigated the subcortical structural abnormalities. Therefore, we sought to determine whether focal subcortical grey matter (GM changes might be present in MDD at an early stage. We recruited 30 first episode, untreated patients with major depressive disorder (MDD and 26 healthy control subjects. Voxel-based morphometry was used to evaluate cortical grey matter changes, and automated volumetric and shape analyses were used to assess volume and shape changes of the subcortical GM structures, respectively. In addition, probabilistic tractography methods were used to demonstrate the relationship between the subcortical and the cortical GM. Compared to healthy controls, MDD patients had significant volume reductions in the bilateral putamen and left thalamus (FWE-corrected, p < 0.05. Meanwhile, the vertex-based shape analysis showed regionally contracted areas on the dorsolateral and ventromedial aspects of the bilateral putamen, and on the dorsal and ventral aspects of left thalamus in MDD patients (FWE-corrected, p < 0.05. Additionally, a negative correlation was found between local atrophy in the dorsal aspects of the left thalamus and clinical variables representing severity. Furthermore, probabilistic tractography demonstrated that the area of shape deformation of the bilateral putamen and left thalamus have connections with the frontal and temporal lobes, which were found to be related to major depression. Our results suggested that structural abnormalities in the putamen and thalamus might be present in the early stages of MDD, which support the role of subcortical structure in the pathophysiology of MDD. Meanwhile, the present study showed that these subcortical structural abnormalities might be

    Glycogen synthase kinase-3 β (GSK3β) is an intracellular enzyme directly implicated in several neural processes relevant to bipolar disorder (BD) pathophysiology. GSK3β is also an important target for lithium and antidepressants. When phosphorylated at serine-9, GSK3β becomes inactive. Few studies evaluated serine-9 phosphorylated GSK3β (phospho-GSK3β) levels in BD subjects in vivo and no study has assessed it specifically in bipolar depression. Also, the effect of lithium monotherapy on GSK3β has never been studied in humans. In 27 patients with bipolar depression, total GSK3β and phospho-GSK3β were assessed in platelets by enzyme immunometric assay. Subjects were evaluated before and after 6 weeks of lithium treatment at therapeutic levels. Healthy subjects (n = 22) were used as a control group. No differences in phospho-GSK3β or total GSK3β were observed when comparing drug-free BD subjects in depression and healthy controls. Baseline HAM-D scores were not correlated with phospho-GSK3β and total GSK3β levels. From baseline to endpoint, lithium treatment inactivated GSK3β by significantly increasing phospho-GSK3β levels (p = 0.010). Clinical improvement (baseline HAM-D - endpoint HAM-D) negatively correlated with the increase in phospho-GSK3β (p = 0.03). The present results show that lithium inactivates platelet GSK3β in BD during mood episodes. No direct association with pathophysiology of BD was observed. Further studies are needed to clarify the role of GSK3β as a key biomarker in BD and its association with treatment response as well as the relevance of GSK3β in other neuropsychiatric disorders and as a new therapeutic target per se.

    BACKGROUND: In long-term follow-up studies on depression, the Eysenck Neuroticism Scale (ENS) at the score level of dysthymia has been found to be valid at predicting poor outcome. AIMS: The ENS dysthymia level was compared with the Beck Depression Inventory (BDI) level to predict the prevalence......, and HAM-D from 2005-2007. At 5-year follow-up from 2011-2013, the participants were re-assessed by HAM-D. The HAM-D was used to measure depressive symptoms at the 5-year follow-up. The Mokken analysis was used to indicate scalability of the BDI and ENS. RESULTS: A total of 185 participants were available...... as measured by the two self-rating scales ENS and BDI can be considered part of a 'double depression' in patients with first episode depression, implying an existence of depressive symptoms at the 5-year follow-up. CLINICAL IMPLICATIONS: Evaluation of dysthymia or neuroticism is important to perform, even...

  12. Mild cognitive impairment, poor episodic memory, and late-life depression are associated with cerebral cortical thinning and increased white matter hyperintensities

    Full Text Available In various independent studies to date, cerebral cortical thickness and white matter hyperintensity (WMH volume have been associated with episodic memory, depression, and mild cognitive impairment (MCI. The aim of this study was to uncover variations in cortical thickness and WMH volume in association with episodic memory, depressive state, and the presence of MCI simultaneously in a single study population. The participants were 186 individuals with MCI (clinical dementia rating [CDR] of 0.5 and 136 healthy elderly controls (HCs; CDR of 0 drawn from two community-based cohort studies in northern Japan. We computed cerebral cortical thickness and WMH volume by using MR scans and statistically analyzed differences in these indices between HCs and MCI participants. We also assessed the associations of these indices with memory performance and depressive state in participants with MCI. Compared with HCs, MCI participants exhibited thinner cortices in the temporal and inferior parietal lobes and greater WMH volumes in the corona radiata and semioval center. In MCI participants, poor episodic memory was associated with thinner cortices in the left entorhinal region and increased WMH volume in the posterior periventricular regions. Compared with non-depressed MCI participants, depressed MCI participants showed reduced cortical thickness in the anterior medial temporal lobe and ambient gyrus adjacent to the amygdala bilaterally, as well as greater WMH volume as a percentage of the total intracranial volume (WMHr. A higher WMHr was associated with cortical thinning in the frontal, temporal, and parietal regions in MCI participants. These results demonstrate that episodic memory and depression are associated with both cortical thickness and WMH volume in MCI participants. Additional longitudinal studies are needed to clarify the dynamic associations and interactions among these indices.

    Full Text Available Lactating rat dams were submitted to short episodes (1, 2 or 3 weeks of nutritional restriction by receiving the "regional basic diet" (RBD, with 8% protein of low-income human populations of Northeast Brazil. Their pups were then studied regarding the developmental effects on body and brain weights. When the rats reached adulthood, cortical susceptibility to the phenomenon of spreading depression (SD was evaluated by performing electrophysiological recordings on the surface of the cerebral cortex. SD was elicited at 20-min intervals by applying 2% KCl for 1 min to a site on the frontal cortex and its occurrence was monitored at 2 sites in the parietal region by recording the electrocorticogram and the slow potential change of SD. When compared to control rats fed a commercial diet with 23% protein, early malnourished rats showed deficits in body and brain weights (10% to 60% and 3% to 15%, respectively, as well as increases in velocity of SD propagation (10% to 20%. These effects were directly related to the duration of maternal dietary restriction, with pups malnourished for 2 or 3 weeks presenting more intense weight and SD changes than those malnourished for 1 week. The effects of 1-week restrictions on SD were less evident in the pups malnourished during the second week of lactation and were more evident in pups receiving the RBD during the third week. The results indicate that short episodes of early malnutrition during the suckling period can affect body and brain development, as well as the cortical susceptibility to SD during adulthood. The data also suggest that the third week of lactation is the period during which the brain is most sensitive to malnutrition, concerning the effects on SD

    Aims The objective of this study was to examine the associations between compulsive buying (CB) and substance dependence/abuse, major depressive episode (MDE), and generalized anxiety disorder (GAD) at mean age 43. Methods Participants came from a community-based random sample of residents in two New York counties (N=548). The participants were followed from adolescence to early midlife. The mean age of participants at the most recent interview was 43.0 (SD=2.8). Fifty five percent of the participants were females. Over 90% of the participants were white. The prevalence of substance dependence/abuse, MDE, and GAD (during the past 5 years before the interviews) was 6.6%, 13.7, and 11.5%, respectively. Results Logistic regression analyses showed that CB was significantly associated with substance dependence/abuse [Adjusted Odds Ratio (A.O.R.) = 1.60], MDE (A.O.R. = 1.70), and GAD (A.O.R. = 1.63), despite controlling for substance dependence/abuse, MDE, and GAD, respectively, at mean age 37, and demographic factors. Discussion Since the study sample is limited to predominantly white participants (over 90%) with a close association to a small geographic area, the findings may not be generalizable to racial/ethnic minority groups or individuals living in other parts of the country. Nevertheless, it is important that clinicians treating substance dependence/abuse, MDE, and GAD consider the role of CB. PMID:27215919

    Purpose: To investigate cerebral and cerebellar gray matter abnormalities in patients with first-episode major depressive disorder (MDD). Materials and methods: We examined the structural difference in regional gray matter density (GMD) between 22 first-episode MDD patients and 30 age-, gender- and education-matched healthy controls by optimized voxel-based morphometry (VBM) based on magnetic resonance imaging. Results: Compared with healthy controls, MDD patients showed decreased GMD in the right medial and left lateral orbitofrontal cortex, right dorsolateral prefrontal cortex (DLPFC), bilateral temporal pole, right superior temporal gyrus, bilateral anterior insular cortex, left parahippocampal gyrus, and left cerebellum. In addition, in MDD patients, there was a negative correlation between GMD values of the right DLPFC and the score of the depression rating scale. Conclusions: Our findings provided additional support for the involvement of limbic-cortical circuits in the pathophysiology of MDD and preliminary evidence that a defect involving the cerebellum may also be implicated.

    The aim of the present study was to investigate the social cognitive functioning of participants with depression when compared with healthy controls, and to assess the impact of symptom severity. One hundred and eight patients with depression (66 remitted and 42 current) and 52 healthy controls were assessed using the Wechsler Advanced Clinical Solutions: Social Perception Subtest, measuring facial affect recognition in isolation and in combination with prosody and body language interpretation. When healthy controls, remitted depression and currently depressed groups were compared, no associations were found on any of the social cognition subscales. Severity of depressive and anxious symptoms predicted performance on all social cognition subscales in currently depressed participants, controlling for age, gender, education and psychotropic medication. Affective depressive symptoms were inversely related to ACS Pairs and Prosody subscales, while somatic symptoms were inversely related to the ACS Affect Recognition and Total scores. There was no association between severity and the WAIS ACS in remitted depression participants. People with MDD exhibiting more severe depressive and anxious symptoms and a cluster of affective symptoms have greater difficulty undertaking complex social cognitive tasks. Given the state like nature to these deficits, these impairments may cause problems with day to day functioning and have implications in targeted therapeutic interventions.

    Depression is highly prevalent worldwide and associated with significant morbidity and mortality. Approximately 340 million people worldwide suffer from depression at any given time. Based on estimates from the World Health Organization (WHO), depression is responsible for the greatest proportion of burden associated with non-fatal health outcomes and accounts for approximately 12% total years lived with disability. Probably no single risk factor can be completely isolated in major depressive disorder (MDD), as interactions between many sources of vulnerability are the most likely explanation. Buttressing the identification of grief, demoralization, hopelessness and styles of psychological coping of the depressed patient are vital, ongoing scientific developments that flow from an increased understanding of this interplay amongst the immune system, endocrine system and brain. The rapidly accumulating body of neurobiological knowledge has catalyzed fundamental changes in how we conceptualize depressive symptoms and has important implications regarding the treatment and even prevention of depressive symptoms in patients.

    We examined whether the reserve capacity model can be extended to cognitive outcomes among older African Americans. Two hundred and ninety-two non-Hispanic Whites and 37 African Americans over age 54 participated in the normative study for the NIH Toolbox for the Assessment of Neurological and Behavioral Function. Multiple-group path analysis showed that associations between depressive symptoms and cognition differed by race, independent of age, education, reading level, income, health, and recruitment site. Depressive symptoms were associated with slowed processing speed among Whites and worse task-switching, inhibition, and episodic memory among African Americans. African Americans may be more vulnerable to negative effects of depression on cognition than non-Hispanic Whites. Further research is needed to explicate the psychological and neurobiological underpinnings of this greater vulnerability. PMID:25280795

    Cognitive theories of depression posit that people’s thoughts, inferences, attitudes, and interpretations, and the way in which they attend to and recall information, can increase their risk for depression. Three mechanisms have been implicated in the relation between biased cognitive processing and the dysregulation of emotion in depression: inhibitory processes and deficits in working memory, ruminative responses to negative mood states and negative life events, and the inability to use pos...

    Smaller hippocampal volumes have been associated with major depressive disorder (MDD). The hippocampus consists of several subfields that may be differentially related to MDD. We investigated the association of occurrence of major depressive episodes (MDEs), assessed five times over seven years, with hippocampal subfield and entorhinal cortex volumes at 7 tesla MRI. In this prospective study of randomly selected general practice attendees, MDEs according to DSM-IV-R criteria were assessed at baseline and after 6, 12, 39 and 84 months follow-up. At the last follow-up, a T2 (0.7 mm(3)) 7 tesla MRI scan was obtained in 47 participants (60±10 years). The subiculum, cornu ammonis (CA) 1 to 3, dentate gyrus&CA4 and entorhinal cortex volumes were manually segmented according a published protocol. Of the 47 participants, 13 had one MDE and 5 had multiple MDEs. ANCOVAs, adjusted for age, sex, education and intracranial volume, revealed no significant differences in hippocampal subfield or entorhinal cortex volumes between participants with and without an MDE in the preceding 84 months. Multiple episodes were associated with smaller subiculum volumes (B=-0.03 mL/episode; 95% CI -0.06; -0.003), but not with the other hippocampal subfield volumes, entorhinal cortex, or total hippocampal volume. A limitation of this study is the small sample size which makes replication necessary. In this exploratory study, we found that an increasing number of major depressive episodes was associated with smaller subiculum volumes in middle-aged and older persons, but not with smaller volumes in other hippocampal subfields or the entorhinal cortex.

    Full Text Available Depression has a negative impact on activities of daily living, cognitive performance, and quality of life. Despite the high prevalence of depressive symptoms in Parkinson disease (PD, this important clinical feature is under-recognized by physicians. Effective diagnosis, assessment and treatment of depression are, therefore, important aspects of PD management. In this article, we review the literature concerning depression associated with PD, paying specific attention to clinical presentation, diagnosis, etiology, and the principles of management and treatment. The efficacy and safety of antidepressants must rely on empiric assessments of known risks and putative benefits to guide treatment decisions.

    Introduction Current studies of depression among people living with HIV focus on describing its point prevalence. Given the fluctuating nature of depression and its profound impacts on clinical and quality-of-life outcomes, this study aimed to examine the prevalence, recurrence and incidence of current depressive symptoms and its underlying catalysts longitudinally and systematically among these individuals. Methods We conducted a prospective cohort study between October 1, 2007 and December 31, 2012 using longitudinal linked data sources. Current depressive symptoms was identified using the Centre for Epidemiologic Studies Depression Scale or the Kessler Psychological Distress Scale, first at baseline and again during follow-up interviews. Multivariable regressions were used to characterize the three outcomes. Results Of the 3,816 HIV-positive participants, the point prevalence of depressive symptoms was estimated at 28%. Of the 957 participants who were identified with depressive symptoms at baseline and who had at least two years of follow-up, 43% had a recurrent episode. The cumulative incidence among 1,745 previously depressive symptoms free participants (at or prior to baseline) was 14%. During the five-year follow-up, our multivariable models showed that participants with greater risk of recurrent cases were more likely to feel worried about their housing situation. Participants at risk of developing incident cases were also likely to be younger, gay or bisexual, and unable to afford housing-related expenses. Conclusions Depressive symptoms are prevalent and likely to recur among people living with HIV. Our results support the direction of Ontario’s HIV/AIDS Strategy to 2026, which addresses medical concerns associated with HIV (such as depression) and the social drivers of health in order to enhance the overall well-being of people living with or at risk of HIV. Our findings reinforce the importance of providing effective mental health care and

    Full Text Available Based on the current study, the clinical characteristics of unipolar depression in the clinical picture of schizophrenia with the paroxysmal type of disease course are presented. Given the concomitant depression with phobic symptoms, the following clinical variants are marked: depression with generalized social phobia and/or anthropophobia and depression with generalized pathological body sensations and hypochondriacal phobias. In other words, we are talking about a necessity to allocate a special type of schizophrenia with affective structure episodes and comorbid neurosis-like symptoms. Information on the basic treatment strategy of schizophrenia with depressive structure episodes and comorbid neurosis-like symptoms in everyday psychiatric practice is also provided.

    Abnormalities of REM sleep, i.e. shortening of REM latency, lengthening of the duration of the first REM period and heightening of REM density, which are frequently observed in patients with a Major Depressive Disorder (MDD), have attracted considerable interest. Initial hopes that these aberrant patterns of sleep constitute specific markers for the primary/endogenous subtype of depression have not been fulfilled. The specificity of REM sleep disinhibition for depression in comparison to other psychopathological groups is also challenged. Demographic variables like age and sex exert strong influences on sleep physiology and must be controlled when searching for specific markers of depressed sleep. It is still an open question whether abnormalities of sleep are state-markers or trait-markers of depression. Beyond baseline studies, the cholinergic REM induction test (CRIT) indicated a heightened responsitivity of the REM sleep system to cholinergic challenge in depression compared with healthy controls and other psychopathological groups, with the exception of schizophrenia. A special role for REM sleep in depression is supported by the well known REM sleep suppressing effect of most antidepressants. The antidepressant effect of selective REM deprivation by awakenings stresses the importance of mechanisms involved in REM sleep regulation for the understanding of the pathophysiology of depressive disorders. The positive effect of total sleep deprivation on depressive mood which can be reversed by daytime naps, furthermore emphasizes relationships between sleep and depression. Experimental evidence as described above instigated several theories like the REM deprivation hypothesis, the 2-process model and the reciprocal interaction model of nonREM-REM sleep regulation to explain the deviant sleep pattern of depression. The different models will be discussed with reference to empirical data gathered in the field.

    Although major depressive disorder (MDD) is associated with disability, some persons do function well despite their illness. Aim of the present study was to examine the effect of illness characteristics and comorbid mental disorders on various aspects of disability among persons with a current MDD episode. Data were derived from 607 participants with a current MDD based on the Composite International Diagnostic Interview (CIDI). Severity was assessed via the Inventory of Depressive Symptoms self-report (IDS-SR). For disability three outcome measures were used: World Health Organization Disability Assessment Schedule II (WHODAS) disability and its 7 dimensions, days out of role, and work absence. Using multiple regression analysis the effects of MDD characteristics and comorbid mental disorders were estimated. The IDS-SR score was the best predictor of all disability outcomes. Of the comorbid mental disorders, agoraphobia was significantly associated with overall disability. Collectively, all illness characteristics accounted for 43% of variance in WHODAS disability, 13% in days out of role and 10% in work absence, suggesting substantial unexplained variance. Only self-report measures of disability were used. There were no assessments of other diagnoses than depressive, anxiety and alcohol use disorders. Although heterogeneity in disability of persons with current MDD is partially explained by illness characteristics of MDD (especially symptom severity) and comorbid mental disorders, most of the variance is not accounted for.

    Background Affective bias is a common feature of depressive disorder. However, a lack of longitudinal studies means that the temporal relationship between affective bias and depression is not well understood. One group where studies of affective bias may be particularly warranted is the adolescent offspring of depressed parents, given observations of high rates of depression and a severe and impairing course of disorder in this group. Methods A two wave panel design was used in which adolescent offspring of parents with recurrent depression completed a behavioural task assessing affective bias (The Affective Go/No Go Task) and a psychiatric interview. The affective processing of adolescents with current, prior and future depressive disorder was compared to that of adolescents free from disorder. Results Adolescents with current depression and those who developed depression at follow-up made more commission errors for sad than happy targets compared to adolescents free from disorder. There was no effect of prior depression on later affective processing. Limitations Small cell sizes meant we were unable to separately compare those with new onset and recurrent depressive disorder. Conclusions Valence-specific errors in behavioural inhibition index future vulnerability to depression in adolescents already at increased risk and may represent a measure of affective control. Currently depressed adolescents show a similar pattern of affective bias or deficits in affective control. PMID:25527997

    Objective  To investigate the prevalence, characteristics and correlates of depressive symptoms in first episode schizophrenic patients. Methods To examine 164 first episode schizophrenic patients at the time of admission and at 3,6,9, and 12 months after starting treatment using the HAMD, BPRS, the Chinese version of SANS, CGI and GAF. Results 71% of the patients had depressive symptoms (mild or more) at damission, but the prevalence of depressive symptoms dropped to a mean of 12% during the recovery period. The most prominent depressive symptoms during the acute phase of schizophrenia were ‘cognitive disturbance’ and ‘retardation’ (the respective subscales constituted 35% and 29% of the total HAMD score on admission). Depressive symptoms improved in parallel with the schizophrenic illness. The severity of depressive symptoms was not related to gender, age of onset, educational level, duration of prodromal period or duration of illness. At admission the severity of depressive symptoms was only related to the BPRS anxiety and depression subscale score, but during the recovery period the HAMD total score was significantly correlated with all of the other clinical scales. The level of depressive symptoms at admission and at three months after starting treatment was not related to the subsequent course of positive or negative symptoms. Conclusions Depressive symptoms appeared to be a separate symptom cluster during the acute phase of first episode schizophrenia. The severity of depressive symptoms did not predict the clinical outcome of first episode schizophrenic patients.%目的探讨首发精神分裂症病人抑郁症状的发生率、特征及相关因素。方法于入院、治疗3、6、9、12月时用汉密尔顿抑郁量表(HAMD)、简明精神病评定量表(BPRS)、阴性症状量表中文版(SANS-CV)、临床总体印象量表(CGI)及功能总体评定量表(GAF)对164例首发精神分裂症患者进行评定。结果急性期首发精神

    Cognitive theories of depression posit that people's thoughts, inferences, attitudes, and interpretations, and the way in which they attend to and recall information, can increase their risk for depression. Three mechanisms have been implicated in the relation between biased cognitive processing and the dysregulation of emotion in depression: inhibitory processes and deficits in working memory, ruminative responses to negative mood states and negative life events, and the inability to use positive and rewarding stimuli to regulate negative mood. In this review, we present a contemporary characterization of depressive cognition and discuss how different cognitive processes are related not only to each other, but also to emotion dysregulation, the hallmark feature of depression. We conclude that depression is characterized by increased elaboration of negative information, by difficulties disengaging from negative material, and by deficits in cognitive control when processing negative information. We discuss treatment implications of these conclusions and argue that the study of cognitive aspects of depression must be broadened by investigating neural and genetic factors that are related to cognitive dysfunction in this disorder. Such integrative investigations should help us gain a more comprehensive understanding of how cognitive and biological factors interact to affect the onset, maintenance, and course of depression.

    Although the presence of psychosis during major depression has been identified as a predictor of later developing mania or hypomania, to our knowledge there have been no studies examining rates and predictors of developing a manic or hypomanic episode in patients who were admitted for their first psychiatric hospitalization for major depressive disorder with psychosis (MDDP). Patients admitted for their first psychiatric hospitalization, with a Diagnostic and Statistical Manual of Mental Disorders (fourth edition) diagnosis of MDDP, were recruited from three sites (N = 157) and evaluated prospectively for up to 2 years to identify new symptoms of mania or hypomania. Family history was assessed using the Family History-Research Diagnostic Criteria Interview. Clinical and demographic factors associated with developing a manic or hypomanic episode were identified using stepwise logistic regression. Thirteen percent (n = 21) of patients with MDDP developed mania or hypomania within the follow-up period. Family history of affective disorders and age at onset of MDDP were not predictive of switch. MDDP patients who were treated with antidepressants were four times less likely to develop mania or hypomania than those who were not treated with antidepressants, after controlling for site differences. Our findings suggest that within the first 1 to 2 years following first hospitalization for MDDP, a subset of patients will develop mania or hypomania. Additionally, our data suggest that antidepressant exposure does not increase the risk of, and may be protective against, developing a manic or hypomanic episode in patients hospitalized for MDDP.

    In Kv1.1, single point mutants found below the channel activation gate at residue V408 are associated with human episodic ataxia type-1, and impair channel function by accelerating decay of outward current during periods of membrane depolarization and channel opening. This decay is usually attributed to C-type inactivation, but here we provide evidence that this is not the case. Using voltage-clamp fluorimetry in Xenopus oocytes, and single-channel patch clamp in mouse ltk- cells, of the homologous Shaker channel (with the equivalent mutation V478A), we have determined that the mutation may cause current decay through a local effect at the activation gate, by destabilizing channel opening. We demonstrate that the effect of the mutant is similar to that of trapped 4-aminopyridine in antagonizing channel opening, as the mutation and 10 mm 4-AP had similar, nonadditive effects on fluorescence recorded from the voltage-sensitive S4 helix. We propose a model where the Kv1.1 activation gate fails to enter a stabilized open conformation, from which the channel would normally C-type inactivate. Instead, the lower pore lining helix is able to enter an activated-not-open conformation during depolarization. These results provide an understanding of the molecular etiology underlying episodic ataxia type-1 due to V408A, as well as biophysical insights into the links between the potassium channel activation gate, the voltage sensor and the selectivity filter.

    Full Text Available Introduction: Depression is a common disorder that is often associated with other mental and physical disorders. One of the innovative approaches applied in depressed patients is transcranial direct current stimulation. Objective: The aim of this study is to determine the effectiveness of transcranial direct electrical stimulations on reducing the severity of depression and negative automatic thoughts. Method: This study is a quasi-experimental study. The population of it all depressed women formed in Tehran in 2015-16. A total of 24 subjects were selected by convenience sampling and randomly assigned into two test (n=12 and control (n=12 groups. The assessment tool used in the clinical interview was Beck Depression Inventory (BDI- Form 21 and automatic thoughts questionnaire (ATQ respectively. The treatment sessions with a transcranial direct current stimulation (tDCS included 15-20 min anodal stimulation of T3 region, and Kathodal stimulation of FD1 with a current of 2 mA. Data were analyzed using analysis of covariance and a dependent t-test. Results: Analysis of the data using analysis of covariance showed that there is a significant difference between tDCS and control groups in the rates of depression (p<0.05. There was also a significant difference between tDCS and control groups in terms of belief and the frequency of automatic thoughts (p<0.05. Conclusion: According to the results, it seems that transcranial direct current stimulation can reduce the severity of depression. Therefore, psychologists and psychotherapists can use it as a method of intervention used to improve symptoms in patients with depression

  17. Neural state and trait bases of mood-incongruent memory formation and retrieval in first-episode major depression.

    Mood-congruent cognitive biases constitute critical factors for the vulnerability to depression and its maintenance. One important aspect is impaired memory for positive information during depression and after recovery. To elucidate its state (during depression only) and trait (during depression and recovery) related neural bases, we investigated medication free depressed, recovered, and healthy individuals with functional MRI while they memorized and recognized happy and neutral face stimuli. The imaging results revealed group differences in mood-incongruent successful memory encoding and retrieval activity already in the absence of significant memory performance differences. State effects were observed in the amygdala and posterior cingulate cortex. Whereas the amygdala was generally involved in memory formation, its activity predicted subsequent forgetting of neutral faces in depressed patients. Furthermore, the amygdala and posterior cingulate cortex were involved in memory retrieval of happy faces in depressed patients only. Trait effects were observed in the fusiform gyrus and prefrontal cortex. The fusiform gyrus was involved in memory formation and retrieval of happy faces in both patient groups, whereas it was involved in memory formation and retrieval of neutral faces in healthy individuals. Similar trait effects were observed during memory retrieval in the orbitofrontal cortex and left inferior frontal gyrus. Thus, while memory processing of positive information in the amygdala and posterior cingulate cortex is biased during depression only, memory processing in the fusiform gyrus and prefrontal cortex is biased also after recovery. These distinct neural mechanisms may respectively constitute symptom maintenance and cognitive vulnerability factors for depression.

    2016-10-01

    Depression in cancer survivors is a major concern and is associated with poor health related quality of life (HRQOL). Delaying or forgoing care due to depression may further augment poor HRQOL. Although several studies have documented depression as a barrier to health care utilization in non-cancer populations, the impact of current depression on health care utilization among adult cancer survivors (ACS) has not been fully elucidated. The objective of this study was to examine the association between current depression and health care utlization among ACS. Data from the 2010 Behavioral Risk Factor Surveillance System involving ACS were used in this study. The Patient Health Questionnaire 8 (PHQ-8) item scale was used to measure current depression. Two indicators of health care utilization were examined as outcomes of interest: cost as a barrier to medical care and not having a routine care. Logistic regression models were used to examine the association between current depression and health care utilization. Overall, 13.0% of ACS reported symptoms of current depression. Despite no differences in having access to care, current depression in ACS was a significant barrier to health care utilization: cost as a barrier to medical care (AOR: 5.3 [95% CI: 3.1-9.1]), and not having a routine care (AOR: 2.0 [95% CI: 1.2-3.3]). Our findings have implications for future studies to further understand the association between depression and health care utlization among ACS, its impact on their overall wellbeing, and efforts to detect and treat depression in ACS. Routine assessment of depression in ACS and effective treatment interventions may aid in seeking timely and appropriate medical care. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Some elderly patients on chronic lithium therapy for bipolar disorder and their doctors may be faced with a therapeutic dilemma over whether or not to continue prescribing/taking lithium given their increased risk of reduced renal function. We present the case of a 78-year-old woman with bipolar disorder who discontinued lithium therapy due to increased risk factors for renal injury. After discontinuation, she experienced markedly decreased appetite secondary to a depressive episode, and developed acute renal failure, which subsequently progressed to a more advanced stage of chronic kidney disease. This case suggests that extreme care must be taken to prevent the recurrence of depression in elderly patients with bipolar disorder who discontinue lithium therapy, even when they had been emotionally stable for a long time while receiving lithium. Medications other than lithium for bipolar disorder may be needed at the time lithium therapy is discontinued. 2014 BMJ Publishing Group Ltd.

    Full Text Available Background. Previous volume-based regional homogeneity (ReHo studies neglected the intersubject variability in cortical folding patterns. Recently, surface-based ReHo was developed to reduce the intersubject variability and to increase statistical power. The present study used this novel surface-based ReHo approach to explore the brain functional activity differences between first-episode, drug-naïve MDD patients and healthy controls. Methods. Thirty-three first-episode, drug-naïve MDD patients and 32 healthy controls participated in structural and resting-state fMRI scans. MDD patients were rated with a 17-item Hamilton Rating Scale for Depression prior to the scan. Results. In comparison with the healthy controls, MDD patients showed reduced surface-based ReHo in the left insula. There was no increase in surface-based ReHo in MDD patients. The surface-based ReHo value in the left insula was not significantly correlated with the clinical information or the depressive scores in the MDD group. Conclusions. The decreased surface-based ReHo in the left insula in MDD may lead to the abnormal top-down cortical-limbic regulation of emotional and cognitive information. The surface-based ReHo may be a useful index to explore the pathophysiological mechanism of MDD.

    Previous structural imaging studies have found evidence of brain morphometric changes in patients with major depressive disorder (MDD), but these studies rarely excluded compounding effects of certain important factors, such as medications and long duration of illnesses. Furthermore, the neurobiological mechanism of the macroscopic findings of structural alterations in MDD patients remains unclear. In this study, we utilized magnetization transfer imaging, a quantitative measure of the macromolecular structural integrity of brain tissue, to identify biophysical alterations, which are represented by a magnetization transfer ratio (MTR), in MDD patients. To ascertain whether MTR changes occur independent of volume loss, we also conduct voxel-based morphometry (VBM) analysis. The participants included 27 first-episode, drug-naive MDD patients and 28 healthy controls matched for age and gender. Whole-brain voxel-based analysis was used to compare MTR and gray matter volume across groups and to analyse correlations between MTR and age, symptom severity, and illness duration. The patients exhibited significantly lower MTR in the left superior parietal lobule and left middle occipital gyrus compared with healthy controls, which may be related to the attentional and cognitive dysfunction in MDD patients. The VBM analysis revealed significantly increased gray matter volume in right postcentral gyrus in MDD patients. These findings in first-episode, drug-naive MDD patients may reflect microstructural gray matter changes in the parietal and occipital cortices close to illness onset that existed before volume loss, and thus potentially provide important new insight into the early neurobiology of depression.

    Full Text Available A person’s speech makes it possible to identify significant indicators which reflect certain characteristics of his/her personality organization, but also can vary depending on the relevance of specific moments of the session and the symptoms type. The present study analyzed 10 completed and successful therapeutic processes using a mixed methodology. The therapies were video–and audio-taped, as well as observed through a one-way mirror by trained observers. All the sessions of each therapy were considered (N = 230 in order to identify, delimit, transcribe, and analyze Change Episodes (CEs = 24 and Stuck Episodes (SEs = 26. Each episode was made up by patients’ speech segments (N = 1,282, which were considered as the sampling unit. The Therapeutic Activity Coding System (TACS-1.0 was used to manually code each patient’s verbalizations, nested within episodes and individuals, in order to analyze them using Hierarchical Linear Modelling (HLM. The findings suggest that anaclitic patients tend to use more verbalizations in order to ask for feedback or to be understood by their therapists (attune, whereas introjective patients tend to use more verbalizations in order to construct new meanings (resignify during therapeutic conversation, but especially during SEs. Clinical implications to enrich the therapeutic practice are discussed.

    The frequently observed co-occurrence of depressive disorders and inflammatory diseases suggests a close connection between the nervous and the immune systems. Increased pro-inflammatory and type 1 cytokines, such as interleukin (IL)-1, tumour necrosis factor (TNF)-α and interferon (IFN)-γ, appear to be an important link. Cytokines are synthesized by immune cells in the blood and peripheral tissues and by glial cells in the central nervous system (CNS). Evidence suggests that the blood-brain barrier (BBB) is permeable to cytokines and immune cells, and that afferent nerves, e.g. the vagus nerve, mediate the communication between peripheral inflammatory processes and CNS. Cytokines such as IL-1ß, TNF-α and IFN-γ seem to contribute to the pathophysiology of depression by activating monoamine reuptake, stimulating the hypothalamic-pituitary-adrenocortical (HPA) axis and decreasing production of serotonin due to increased activity of indolamine-2,3-dioxygenase (IDO). However, critical appraisal of these hypotheses is required, because cytokine elevation is not specific to depression. Moreover, several effective antidepressants such as amitriptyline and mirtazapine have been shown to increase cytokine production. When applying immunomodulatory therapies, these drugs may increase the risk of specific side effects such as infections or interact with antidepressant drugs on important functions of the body such as the coagulation system.

    Background Although depression appears to decrease in late life, this could be due to misattribution of depressive symptoms to physical disorders that increase in late life. Methods We investigated this issue by studying age differences in comorbidity of DSM-IV major depressive episodes (MDE) with chronic physical conditions in the WHO World Mental Health (WMH) surveys, a series of community epidemiological surveys carried out in 10 developed countries (n = 51,771) and 8 developing countries (n = 37,265). MDE and other mental disorders were assessed with the Composite International Diagnostic Interview (CIDI). Organic exclusion rules were not used to avoid inappropriate exclusion of cases with physical comorbidity. Physical conditions were assessed with a standard chronic conditions checklist. Results Twelve-month DSM-IV/CIDI MDE was significantly less prevalent among respondents ages 65+ than younger respondents in developed but not developing countries. Prevalence of comorbid mental disorders generally either decreased or remained stable with age, while comorbidity of MDE with mental disorders generally increased with age. Prevalence of physical conditions, in comparison, generally increased with age, while comorbidity of MDE with physical conditions generally decreased with age. Depression treatment was lowest among the elderly in developed and developing countries. Conclusions The weakening associations between MDE and physical conditions with increasing age argue against the suggestion that the low estimated prevalence of MDE among the elderly is due to increased confounding with physical disorders. Future study is needed to investigate processes that might lead to a decreasing impact of physical illness on depression among the elderly. PMID:20037917

    Suicide is a leading cause of death among young adults and the rate of suicide has been increasing for decades. A depression distress amplification model posits that young adults with comorbid depression and anxiety have elevated suicide rates due to the intensification of their depressive symptoms by anxiety sensitivity cognitive concerns. The current study tested the effects of anxiety sensitivity subfactors as well as the depression distress amplification model in a very large sample of college students with elevated suicide risk. Participants were 721 college students who were at elevated risk of suicidality (scored>0 on the Beck Scale for Suicide Ideation). Consistent with prior work, anxiety sensitivity cognitive concerns, but not physical or social concerns, were associated with suicidal ideation. Consistent with the depression distress amplification model, in individuals high in depression, anxiety sensitivity cognitive concerns predicted elevated suicidal ideation but not among those with low depression. The results of this study corroborate the role of anxiety sensitivity cognitive concerns and the depression distress amplification model in suicidal ideation among a large potentially high-risk group of college students. The depression distress amplification model suggests a specific mechanism, anxiety sensitivity cognitive concerns, that may be responsible for increased suicide rates among those with comorbid anxiety and depression.

    Animal models of mental disorders should ideally have construct, face, and predictive validity, but current animal models do not always satisfy these validity criteria. Additionally, animal models of depression rely mainly on stress-induced behavioral changes. These stress-induced models have limited validity, because stress is not a risk factor specific to depression, and the models do not recapitulate the recurrent and spontaneous nature of depressive episodes. Although animal models exhibiting recurrent depressive episodes or bipolar depression have not yet been established, several researchers are trying to generate such animals by modeling clinical risk factors as well as by manipulating a specific neural circuit using emerging techniques.

    Full Text Available Punishment, when understood as parents' response to undesirable behavior of a child and representing gradual restricting of such behavior, is an essential part of parents' role in the family. In the context of the paradigm of affective regulation, anxiety and depression states represent another unsuccessful attempt of trying to get closer and to find a connection in the relationship. This study, conducted on 197 participants, addressed the connection between punishment in upbringing and behavior disturbances in adulthood. Depressive states in adulthood were statistically significantly, although weakly connected with the experience of corporal punishment, punishment and restitution, and psychological aggression form both parents. Anxiety states were statistically significantly, although weakly connected with the experience of psychological aggression from both parents and with the experience of corporal punishment, and punishment and restitution of the mother. The participants who attained the criteria for diagnosis of depression were more exposed to corporal punishment at the age of 10 years (from both parents, punishment and restitution (from the father and psychological aggression (from the father compared to the participants without the diagnosis of depression. The paradigm of affective regulation is presented as a possible explanation of the connection between experiences of punishment as a way of upbringing in childhood and later mood disorders in adulthood. Punishment during upbringing that is not accompanied by parents' maintaining of the connection with the child can present the first experience of negative affection, which is the core of anxiety and depressive states. The mood disorders in adulthood can be understood as another failure when trying to reestablish the balance between external information and internal experiences that were primarily disturbed by the experience of punishment when growing up.

  16. A Randomized Double-Blind Sham-Controlled Study of Transcranial Direct Current Stimulation for Treatment-Resistant Major Depression

    2012-08-01

    Full Text Available Objectives: Transcranial direct current stimulation (tDCS has demonstrated some efficacy in treatment-resistant major depression (TRD. The majority of previous controlled studies have used anodal stimulation to the left dorsolateral prefrontal cortex (DLPFC and a control location such as the supraorbital region on for the cathode. Several open label studies have suggested effectiveness from anodal stimulation to the left DLPFC combined with cathodal stimulation to the right DLPFC. Thus, this study evaluated the efficacy of tDCS using anodal stimulation to the left DLPFC and cathodal stimulation to the right DLPFC compared to sham tDCS. Methods: Subjects between the ages of 18 and 65 were recruited from a tertiary care university hospital. Twenty-four subjects with TRD and a 17-item Hamilton Depression Rating Scale (HDRS greater than 21 were randomized to receive tDCS or sham tDCS. The rates of remission were compared between the two treatment groups.Results: The remission rates did not differ significantly between the two groups using an intention to treat analysis. More subjects in the active tDCS group had failed a course of electroconvulsive therapy in the current depressive episode. Side effects did not differ between the two groups and in general the treatment was very well tolerated. Conclusion: Anodal stimulation to the left DLPFC and cathodal stimulation to the right DLPFC was not efficacious in TRD. However, a number of methodological limitations warrant caution in generalizing from this study. Ongoing, controlled studies should provide further clarification on the efficacy of this stimulation configuration in TRD.

    Reduced dentate gyrus volume and increased oxidative stress have emerged as potential pathophysiological mechanisms in bipolar disorder. However, the relationship between dentate gyrus volume and peripheral oxidative stress markers remains unknown. Here, we examined dentate gyrus-cornu ammonis (CA) 4 volume longitudinally in patients with bipolar II disorder (BD-II) and healthy controls and investigated whether BD-II is associated with elevated peripheral levels of oxidative stress. We acquired high-resolution structural 3T-magnetic resonance imaging (MRI) images and quantified hippocampal subfield volumes using an automated segmentation algorithm in individuals with BD-II (n=29) and controls (n=33). The participants were scanned twice, at study inclusion and on average 2.4 years later. In addition, we measured peripheral levels of two lipid peroxidation markers (4-hydroxy-2-nonenal [4-HNE] and lipid hydroperoxides [LPH]). First, we demonstrated that the automated hippocampal subfield segmentation technique employed in this work reliably measured dentate gyrus-CA4 volume. Second, we found a decreased left dentate gyrus-CA4 volume in patients and that a larger number of depressive episodes between T1 and T2 predicted greater volume decline. Finally, we showed that 4-HNE was elevated in BD-II and that 4-HNE was negatively associated with left and right dentate gyrus-CA4 volumes in patients. These results are consistent with a role for the dentate gyrus in the pathophysiology of bipolar disorder and suggest that depressive episodes and elevated oxidative stress might contribute to hippocampal volume decreases. In addition, these findings provide further support for the hypothesis that peripheral lipid peroxidation markers may reflect brain alterations in bipolar disorders. © 2016 John Wiley & Sons A/S.

    In this study we investigated whether an Internet-based computerized cognitive behavioral therapy (iCBT) program can decrease the risk of DSM-IV-TR major depressive episodes (MDE) during a 12-month follow-up of a randomized controlled trial of Japanese workers. Participants were recruited from one company and three departments of another company. Those participants who did not experience MDE in the past month were randomly allocated to intervention or control groups (n = 381 for each). A 6-week, six-lesson iCBT program was provided to the intervention group. While the control group only received the usual preventive mental health service for the first 6 months, the control group was given a chance to undertake the iCBT program after a 6-month follow-up. The primary outcome was a new onset of DSM-IV-TR MDE during the 12-month follow-up, as assessed by means of the web version of the WHO Composite International Diagnostic Interview (CIDI), version 3.0 depression section. The intervention group had a significantly lower incidence of MDE at the 12-month follow-up than the control group (Log-rank χ2 = 7.04, p < 0.01). The hazard ratio for the intervention group was 0.22 (95% confidence interval 0.06-0.75), when estimated by the Cox proportional hazard model. The present study demonstrates that an iCBT program is effective in preventing MDE in the working population. However, it should be noted that MDE was measured by self-report, while the CIDI can measure the episodes more strictly following DSM-IV criteria.

    Directory of Open Access Journals (Sweden)

    Lingtao Kong

    Full Text Available BACKGROUND: Convergent studies suggest that morphological abnormalities of frontal-subcortical circuits which involved with emotional and cognitive processing may contribute to the pathophysiology of major depressive disorder (MDD. Antidepressant treatment which has been reported to reverse the functional abnormalities of frontal-subcortical circuits in MDD may have treating effects to related brain morphological abnormalities. In this study, we used voxel-based morphometry method to investigate whole brain structural abnormalities in single episode, medication-naïve MDD patients. Furthermore, we investigated the effects of an 8 weeks pharmacotherapy with fluoxetine. METHODS: 28 single episode, medication-naïve MDD participants and 28 healthy controls (HC acquired the baseline high-resolution structural magnetic resonance imaging (sMRI scan. 24 MDD participants acquired a follow-up sMRI scan after 8 weeks antidepressant treatment. Gray matter volumetric (GMV difference between groups was examined. RESULTS: Medication-naïve MDD had significantly decreased GMV in the right dorsolateral prefrontal cortex and left middle frontal gyrus as well as increased GMV in the left thalamus and right insula compared to HC (P<0.05, corrected. Moreover, treated MDD had significantly increased GMV in the left middle frontal gyrus and right orbitofrontal cortex compared to HC (P<0.05, corrected. No difference on GMV was detected between medication-naïve MDD group and treated MDD group. CONCLUSIONS: This study of single episode, medication-naïve MDD subjects demonstrated structural abnormalities of frontal-subcortical circuitsin the early stage of MDD and the effects of 8 weeks successful antidepressant treatment, suggesting these abnormalities may play an important role in the neuropathophysiology of MDD at its onset.

    Major depressive disorder (MDD) and schizophrenia (SZ) are considered two distinct psychiatric disorders. Yet, they have considerable overlap in symptomatology and clinical features, particularly in the initial phases of illness. The amygdala and prefrontal cortex (PFC) appear to have critical roles in these disorders; however, abnormalities appear to manifest differently. In our study forty-nine drug-naïve, first-episode MDD, 45 drug-naïve, first-episode SZ, and 50 healthy control (HC) participants from 13 to 30 years old underwent resting-state functional magnetic resonance imaging. Functional connectivity (FC) between the amygdala and PFC was compared among the three groups. Significant differences in FC were observed between the amygdala and ventral PFC (VPFC), dorsolateral PFC (DLPFC), and dorsal anterior cingulated cortex (dACC) among the three groups. Further analyses demonstrated that MDD showed decreased amygdala-VPFC FC and SZ had reductions in amygdala-dACC FC. Both the diagnostic groups had significantly decreased amygdala-DLPFC FC. These indicate abnormalities in amygdala-PFC FC and further support the importance of the interaction between the amygdala and PFC in adolescents and young adults with these disorders. Additionally, the alterations in amygdala-PFC FC may underlie the initial similarities observed between MDD and SZ and suggest potential markers of differentiation between the disorders at first onset.

    [Purpose] The aim of this study was to assess the effects of transcranial direct current stimulation (tDCS) on depression and quality of life (QOL) in patients with stroke, by conducting conventional occupational therapy with and without tDCS on 20 patients each. [Subjects and Methods] The experimental group (N=20) received both tDCS and conventional occupational therapy, while the control group (N=20) received false tDCS and conventional occupational therapy. The treatment was conducted 20 times over a four-week period; each session was 30 minutes long. The Beck Depression Inventory (BDI) was administered to score the depression levels in patients before and after the intervention, while the stroke-specific quality of life (SS-QOL) was measured to compare the QOL. [Result] Following the intervention, the patients in the experimental group showed a significant decrease in depression and an increase in the QOL. In contrast, the control group showed no significant changes in depression or QOL. Our findings indicate that tDCS decreased depression while increasing QOL in patients with stroke. [Conclusion] In other words, our study confirmed that the application of tDCS during stroke rehabilitation improves the depression symptoms and QOL in patients.

  3. Episodic Sediment Failure in Northern Flemish Pass, Eastern Canadian Margin: Interplay of Seismicity, Contour Current Winnowing, and Excess Pore Pressures

    Episodic sediment failures are recognised on continental slopes around Flemish Pass and Orphan Basin from multibeam bathymetry, seismic reflection profiles and piston cores. Seismic stratigraphy is tied to published long cores with O-isotope data back to before MIS 6 and carbonate rich Heinrich layers in places produce marker reflections in high-resolution sparker profiles. Heinrich layers, radiocarbon dates and peaks in diatom abundance provide core chronology. Slope sedimentation was strongly influenced by the Labrador Current and the silty muds show architecture characteristic of contourites. Variation in Labrador Current strength is known from the sortable silt proxy over the past 125 ka. Large slope failures were mapped from seismic reflection profiles and their age estimated from seismic stratigraphy (3-5 ka resolution) and in some cases refined from cores (1-3 ka resolution). Large slope failures occurred apparently synchronously over margin lengths of 50-350 km. Such failures were earthquake triggered: other mechanisms for producing laterally extensive synchronous failure do not apply. Triaxial shear measurements show a Su/σ' ratio of typical slope sediment of 0.48, implying considerable stability. However, some silty muds have Atterberg limits that suggest susceptibility to liquefaction under cyclic loading, particularly in Holocene deposits and by analogy those of past full interglacials. Basal failure planes of some large failures correspond with either the last interglacial or the MIS 6 glacial maximum. Comparison with seismological models suggests that the observed slope failures represent earthquakes ranging from Mw ~5.6 to ~7.6. Mean recurrence interval of M = 7 earthquakes at any point on the margin is estimated at 30 ka from seismological models and 40 ka from the sediment failure record. In northern Flemish Pass, a spatial cluster of several failures over 30 ka preceded by a long interval with no failures suggests that some other mechanism has

    Major depressive disorder is a heterogeneous disorder, mostly diagnosed on the basis of symptomatic criteria alone. It would be of great help when specific biomarkers for various subtypes and symptom clusters of depression become available to assist in diagnosis and subtyping of depression, and to enable monitoring and prognosis of treatment response. However, currently known biomarkers do not reach sufficient sensitivity and specificity, and often the relation to underlying pathophysiology is unclear. In this review, we evaluate various biomarker approaches in terms of scientific merit and clinical applicability. Finally, we discuss how combined biomarker approaches in both preclinical and clinical studies can help to make the connection between the clinical manifestations of depression and the underlying pathophysiology.

    Full Text Available Objective: To analyze the current situation of healthcare for depression in Spain, according to psychiatrists opinion, and how it has evolved over the last 20 years, comparativily with the results reported in previous studies of our group. Methods: Throughout 2002, we recorded the opinions of 101 specialists in psychiatry after asking them to fill out structured questionnaires in which they rated care, clinical, therapeutic and care quality. Results: The presence of depressive disorders in healthcare is substantial, despite the high figures for "concealed epidemiology", with an increase in these last 20 years of disorders comorbid with anxiety. Currently, most patients arrive at the psychiatrist having been referred by their general practitioners (GP, as there is now less reluctance in depressive patients to such referral. In the last years there has been an increase in pharmacological treatment, with adverse effects of the drugs representing the major obstacle to non-adherence to such treatment. Selective serotonin reuptake inhibitors (SSRIs constitute the pharmacological group of choice, and are the drugs most commonly used in the treatment of depression, together with venlafaxine. Areas where there is a need for improvement are time devoted to consultation, coordination between GPs and psychiatrists, waiting lists, and resources available to Mental Health Units. Conclusions: Current situation of depression healthcare in Spain has substantially changed in recent years, improving in some aspects, thanks, in part, to the attitudes of GPs with this disorder and to evolution of pharmacological treatment.

    Full Text Available This study investigated work engagement as a baseline predictor of onset of major depressive episode (MDE.The study used a prospective cohort design, conforming to the STROBE checklist. Participants were recruited from the employee population of a private think tank company (N = 4,270, and 1,058 (24.8% of them completed a baseline survey, of whom 929 were included in this study. Work engagement and psychological distress at baseline were assessed as predictor variables. MDE was measured at baseline and at each of the follow-ups as the outcome, using the web-based, self-administered version of the Japanese WHO-CIDI 3.0 depression section based upon DSM-IV-TR/DSM-5 criteria. Cox discrete-time hazards analyses were conducted to estimate hazard ratios (95% confidence intervals CIs.Follow-up rates of participants (N = 929 were 78.4%, 67.2%, and 51.6% at 1-, 2-, and 3-year follow-ups, respectively. The association between work engagement at baseline and the onset of MDE was U-shaped. Compared with a group with low work engagement scores, groups with the middle and high scores showed significantly (HR = 0.19, 95% CI = 0.05 to 0.64; p = 0.007 and marginally significantly (HR = 0.48, 95% CI = 0.20 to 1.15, p = 0.099 lower risks of MDE, respectively, over the follow-ups, after adjusting for covariates. The pattern remained the same after additionally adjusting for psychological distress.The present study first demonstrated work engagement as an important predictor of the onset of MDE diagnosed according to an internationally standard diagnostic criteria of mental disorders.

It has also been inconclusive whether the change in brain metabolites, measured with proton magnetic spectroscopy, could be correlated with the treatment outcome. Methods: Proton magnetic spectroscopy was performed in 29 participants with a first episode of moderate depression occurring in the left dorsolateral prefrontal cortex and left amygdala at baseline and after 8 weeks of antidepressant treatment with escitalopram. The Montgomery-Asberg Depression Rating Scale, the Hamilton Rating Scale for Depression, and the Beck Depression Inventory were used to assess the intensity of depression at baseline and at the endpoint of the study. At endpoint, the participants were identified as responders (n=17 or nonresponders (n=12 to the antidepressant therapy. Results: There was no significant change in the N-acetyl aspartate/creatine ratio (NAA/Cr after treatment with antidepressant medication. The baseline and endpoint NAA/Cr ratios were not significantly different between the responder and nonresponder groups. The correlation between NAA/Cr and changes in the scores of clinical scales were not significant in either group. Conclusion: This study could not confirm any significant changes in NAA after antidepressant treatment in the first episode of moderate depression, or in

    This school-based study aimed to investigate the prevalence of being at risk for depression, bullying behavior, and current smoking among Chinese adolescents in order to explore gender differences in the vulnerability of adolescents with these behaviors to develop a smoking habit. A total of 35,893 high school students sampled from high schools in eighteen cities in China participated in the study from 2011 to 2012. Overall, the prevalence of current smoking was estimated at 6.4%. In total, 1.7% (618) of the participants admitted to bullying others, 5.8% (2071) reported being bullied, 3.5% (1269) were involved in both bullying others and being bullied, and 5.6% (2017) were at high risk for depression. Logistic regression analysis indicated that among girls, with high depression risk, bullying others, being bullied, and both bullying others and being bullied were independently and positively associated with current smoking habits, while the final results among boys showed that bullying others and both bullying others and being bullied were independently associated with an increased risk of current smoking. School-based prevention programs are highly recommended, and we should focus on high-risk students, particularly girls with high risk of depression or involved in school bullying and boys who are involved in school bullying.

    This study identified and examined a set of potential predictors of self-reported negative mood following a depressive mood induction procedure (MIP) in a sample of previously depressed, clinically anxious, and control participants. The examined predictor variables were selected on the basis of previous research and theories of depression, and included symptoms of depression and anxiety, negative and positive affect, negative and positive automatic thoughts, dysfunctional beliefs, rumination, self-concept, and occurrence and perceived unpleasantness of recent negative events. The sample consisted of 33 previously depressed, 22 currently anxious, and 26 non-clinical control participants, recruited from community sources. Participant group status was confirmed through structured diagnostic interviews. Participants completed the Velten negative self-statement MIP as well as self-report questionnaires of affective, cognitive, and psychosocial variables selected as potential predictors of mood change. Symptoms of anxiety were associated with increased self-reported negative mood shift following the MIP in previously depressed participants, but not clinically anxious or control participants. Increased occurrence of recent negative events was a marginally significant predictor of negative mood shift for the previously depressed participants only. None of the other examined variables was significant predictors of MIP response for any of the participant groups. These results identify factors that may increase susceptibility to negative mood states in previously depressed individuals, with implications for theory and prevention of relapse to depression. The findings also identify a number of affective, cognitive, and psychosocial variables that do not appear to influence mood change following a depressive MIP in previously depressed, currently anxious, and control individuals. Limitations of the study and directions for future research are discussed. Current anxiety

    A genetically-informed, quasi-experimental design was used to examine the genetic and environmental processes underlying associations between current parental depressive symptoms and offspring perceived self-competence. Participants, drawn from a population-based Swedish sample, were 852 twin pairs and their male (52%) and female offspring aged 15.7 ± 2.4 years. Parental depressive symptoms were measured using the Center for Epidemiological Studies Depression scale. Offspring perceived self-competence was measured using a modified Harter Perceived Competence Scale. Cousin comparisons and Children of Twins (CoT) designs suggested that associations between maternal depressive symptoms and offspring perceived self-competence were due to shared genetic/environmental liability. The mechanism responsible for father-offspring associations, however, was independent of genetic factors and of extended-family environmental factors, supporting a causal inference. Thus, mothers and fathers may impact offspring perceived self-competence via different mechanisms and unmeasured genetic and environmental selection factors must be considered when studying the intergenerational transmission of cognitive vulnerabilities for depression.

    "I had to wait 110 years to become famous. I wanted to enjoy it as long as possible.", Jeanne Louise Calment (1875-1997). This review summarizes current knowledge of the effects of antidepressant drugs in elderly patients (double-blind placebo (n=27) or active comparator-controlled clinical trials (n=21) indexed in Pubmed in depressed patients aged ≥60) and in aged mice (≥9 months) and middle-aged rats (≥14 months) on depression-related symptoms and cognitive performances. Finally, other potential therapeutic targets for treating depression-related disorders in elderly patients are also addressed (neurogenesis, GABAB receptor, 5-HT4 receptor, mTOR signaling). Overall, the very few published preclinical studies (n=12 in total) in middle-aged and aged rodents seem to suggest that selective serotonin reuptake inhibitors (SSRIs) may be less effective than tricyclic antidepressant drugs (TCAs) in ameliorating depression-like behavior and cognitive functions. On the other hand, results from clinical trials suggest that there is not a marked difference in efficacy and safety profiles of current marketed classes of antidepressant drugs.

    Studies based on Western samples generally show that status characteristics like gender or marital status are associated with better mental health for individuals who occupy advantageous positions, such as men or the married. However, these patterns may not hold in developing regions that differ in important ways from the West. Guided by the Stress Process Model (SPM), this study uses logistic regression to examine the effect of gender, education, and other status characteristics on major depressive episode (MDE). Similarities and differences in these associations across two Western and two African countries are also assessed. Nationally representative data for adults ages 18 years and older are from the World Health Surveys (2002-2004) for Norway (N = 943), the United Kingdom (UK: N = 1195), Ghana (N = 3922), and Kenya (N = 4331). Results indicate a mixed pattern of associations between status characteristics and MDE across the four countries. Norwegian men face higher risk of MDE than Norwegian women-an anomalous finding. With some exceptions, education and employment status are not significantly related to MDE across the countries, providing little support for SPM. Marital status differences in risk of MDE are largest for Norway and smallest for Ghana. For the UK, men face lower risk of MDE than women across levels of mastery, and the gender gap in MDE is larger at higher levels of mastery. Overall, there is some heterogeneity in the associations between status characteristics and MDE even in somewhat similar environments like Ghana and Kenya. This study extends the reach of SPM to settings in sub-Saharan Africa, and contributes to the sparse empirical literature on the prevalence and sociodemographic correlates of MDE in the general populations of Ghana and Kenya.

    Full Text Available Background : Transcranial direct current stimulation (tDCS is a novel non-pharmacological intervention being investigated for the treatment of major depressive disorder (MDD. Objective : To perform an updated review of tDCS for MDD. Method : Systematic review in Medline/PubMed and other databases of all clinical studies evaluating the clinical efficacy of tDCS in MDD, from the first date available to December/2013. Results : Out of 55 articles, 24 were included, being 6 open-label studies; 8 randomized, double-blind, sham-controlled trials; 2 follow-up studies; 2 meta-analyses and 6 case reports. We observed an improvement of 20-40% in depressive symptoms, being slightly better in open studies. Five randomized clinical trials displayed positive results. The meta-analyses presented mixed results; although none included the study of Brunoni et al. (2013 that represents almost 50% of the evaluated sample. Open-label studies and case reports also investigated tDCS in bipolar depression, post-stroke depression and employed different parameters of stimulation. Discussion : TDCS is a novel, promising treatment for MDD. Definite evidence from large, ongoing clinical trials will be available in the next years.

    Predictors of depressive symptoms may differ before and after the first onset of major depression due to stress sensitization. Dependent stressors, or those to which characteristics of individuals contribute, have been shown to predict depressive symptoms in youth. The current study sought to clarify how stressors' roles may differ before and after the first depressive episode. Adolescents (N = 382, aged 11 to 15 at baseline) were assessed at baseline and every 3 months over the course of 2 years with measures of stressors and depressive symptoms. Semi-structured interviews were conducted every 6 months to assess for clinically significant depressive episodes. Hierarchical linear modeling showed a significant interaction between history of depression and idiographic fluctuations in dependent stressors to predict prospective elevations of symptoms, such that dependent stressors were more predictive of depressive symptoms after onset of disorder. Independent stressors predicted symptoms, but the strength of the association did not vary by depression history. These results suggest a synthesis of dependent stress and stress sensitization processes that might maintain inter-episode depressive symptoms among youth with a history of clinical depression.

  4. Agomelatine beyond Borders: Current Evidences of Its Efficacy in Disorders Other than Major Depression

    Directory of Open Access Journals (Sweden)

    Domenico De Berardis

    2015-01-01

    Full Text Available Agomelatine, a melatonergic antidepressant with a rapid onset of action, is one of the most recent drugs in the antidepressant category. Agomelatine’s antidepressant actions are attributed to its sleep-promoting and chronobiotic actions mediated by MT1 and MT2 receptors present in the suprachiasmatic nucleus, as well as to its effects on the blockade of 5-HT2c receptors. Blockade of 5-HT2c receptors causes release of both noradrenaline and dopamine at the fronto-cortical dopaminergic and noradrenergic pathways. The combined actions of agomelatine on MT1/MT2 and 5-HT2c receptors facilitate the resynchronization of altered circadian rhythms and abnormal sleep patterns. Agomelatine appeared to be effective in treating major depression. Moreover, evidence exists that points out a possible efficacy of such drug in the treatment of bipolar depression, anxiety disorders, alcohol dependence, migraines etc. Thus, the aim of this narrative review was to elucidate current evidences on the role of agomelatine in disorders other than major depression.

    Major depressive disorder (MDD) is one of the most disabling diseases worldwide and is a significant public health threat. Current treatments for MDD primarily consist of monoamine-targeting agents and have limited efficacy. However, the glutamate neurotransmitter system has recently come into focus as a promising alternative for novel antidepressant treatments. We review the current data on the glutamate NMDA receptor antagonist ketamine, which has been shown in clinical trials to act as a rapid antidepressant in MDD. We also examine ketamine efficacy on dimensions of psychopathology, including anhedonia, cognition, and suicidality, consistent with the NIMH Research Domain Criteria (RDoC) initiative. Other aspects of ketamine reviewed in this paper include safety and efficacy, different administration methods, and the risks of misuse of ketamine outside of medical settings. Finally, we conclude with a discussion of other glutamatergic agents other than ketamine currently being tested as novel antidepressants. PMID:25649308

    Background Antidepressant tachyphylaxis describes the return of apathetic depressive symptoms, such as fatigue and decreased motivation, despite continued use of a previously effective treatment. Methods Data were collected from a multiphase, double-blind, placebo-controlled study that assessed the efficacy of venlafaxine extended release (ER) during 2 sequential 1-year maintenance phases (A and B) in patients with recurrent major depressive disorder (MDD). The primary outcome was the cumulative probability of tachyphylaxis in patients receiving venlafaxine ER, fluoxetine, or placebo. Tachyphylaxis was defined as Rothschild Scale for Antidepressant Tachyphylaxis (RSAT) scored ≥ 7 in patients with prior satisfactory therapeutic response. A Kaplan-Meier estimate of the cumulative probability of not experiencing tachyphylaxis, and a 2-sided Fisher exact test was used to assess the relationship between tachyphylaxis and recurrence. Results The maintenance phase A population was comprised of 337 patients (venlafaxine ER [n = 129], fluoxetine [n = 79], placebo [n = 129]), whereas 128 patients (venlafaxine ER [n = 43], fluoxetine [n = 45], placebo [n = 40]) were treated during maintenance phase B. No difference in the probability of experiencing tachyphylaxis were observed between the active treatment groups during either maintenance phase; however, a significant difference between venlafaxine ER and placebo was observed at the completion of maintenance phase A. A significant relationship between tachyphylaxis and recurrence was observed. Limitations Despite demonstrating psychometric validity and reliability, the current definition of tachyphylaxis has not been widely studied Conclusions Although no significant differences were observed in the probability of tachyphylaxis among patients receiving active treatment, the relationship between tachyphylaxis and recurrence suggests that tachyphylaxis may be a predrome of recurrence.

    Previous findings suggest that the Papez Circuit may have a role in major depressive disorders. We used atlas-based tract-specific quantification analysis and voxel-based analysis to examine the integrity of white matter tracts involved in mood regulation (including tracts in the Papez Circuit). Diffusion tensor imaging acquired from 35 first-episode, treatment-naive adults with major depressive disorders and 34 healthy adult controls were compared. Our statistical approach compared structural integrity of 11 major white matter tracts between the major depressive disorder and adult controls, as well as illness duration influence in patients. Fractional anisotropy was decreased in the hippocampal cingulum and in the anterior thalamic radiation according to both analytical approaches, all of which were important tracts included in the Papez Circuit. Our results support the role of the Papez Circuit in major depressive disorders with the minimal probability of false positive due to similar findings in both analyses that have complementary advantages. Dysfunction of the Papez Circuit may be a potential marker for studying the pathogenesis of major depressive disorders.

    Research on the association between adverse childhood events (ACEs) and depression among women in Hawaii is scarce. ACEs have been linked to unfavorable health behaviors such as smoking and binge drinking which are more prevalent in the state compared to the US overall. The concomitant presence of ACEs with smoking or binge drinking may explain the excess depression prevalence in Hawaii compared to the national average. Using data of women residing in the state (2010 Hawaii Behavioral Risk Factor Surveillance System Survey), we examined the association between ACEs count or type (household dysfunction and physical, verbal and sexual abuse) and current depressive symptoms (CDS), in addition to modification by current smoking status (smoked >100 cigarettes in a lifetime and currently smoke) and binge drinking (consumed ≥4 alcoholic beverage within the past month and in ≥1 occasion(s)). Evaluation of ACEs before age 18 consisted of 11 indicators. Eight indicators of the Patient Health Questionnaire (PHQ-8) were used to assess CDS. All analyses utilized logistic regression taking into account sampling design. The odds ratio of having CDS between those with versus without ACEs increased per increasing number of ACEs (1 ACE: OR = 2.11, CI = 1.16-3.81; 2 ACEs: OR = 2.90, CI = 1.51-5.58; 3 or 4 ACEs: OR = 3.94, CI = 2.13-7.32; 5+ ACEs: OR = 4.04, CI = 2.26-7.22). Household dysfunction (OR = 2.10, CI = 1.37-3.23), physical abuse (OR = 1.67, CI = 1.08-2.59), verbal abuse (OR = 3.21, CI = 2.03-5.09) and sexual abuse (OR = 1.68, CI = 1.04-2.71) were all positively associated with CDS. Verbal abuse had the strongest magnitude of association. Neither current smoking status nor binge drinking modified the relationship between ACEs count (or type) and CDS. In conclusion, the presence of ACEs among women in Hawaii was indicative of CDS in adulthood, notably verbal abuse. Further, a dose response existed between the number of ACEs and the odds for CDS. The concomitant exposure

    Postpartum depression (PPD) is a common illness, but due to the underlying processes and the diversity of symptoms, some variability is exhibited. The risk of postpartum depression is great if the mother has previously suffered from depression, but there is some evidence that a certain subgroup of women only experience depression during the postpartum period. The study group consisted of 104 mothers with postpartum major depression and a control group of 104 postpartum mothers without depression. The Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) was used for data collection. The severity of depression and other mental symptoms were assessed using several validated rating scales. A history of past depression (82%), including depression during pregnancy (42%) and during the postpartum period (53%), was very common in those with current PPD. Eighteen per cent of mothers with current PPD had previously not had any depressive episodes and four per cent had experienced depression only during the postpartum period. Therefore, pure PPD was rare. The onset of PPD was usually (84%) within six weeks of childbirth. Obsessive-compulsive symptoms, phobic anxiety, paranoid ideation, depressed mood, diminished pleasure/interest, decreased energy, and psychomotor agitation/retardation were common with all kinds of depression histories. Pure PPD was the most similar to the first depressive episode. Nevertheless, the severity of depression, the level of hopelessness, somatisation, interpersonal sensitivity, anxiety, hostility, psychoticism, sleep disturbance, and suicidal ideation were lower, appetite changed less, and concentration was better than in other recurrent depressions. According to this study, PPD is not a homogenous disorder. The time of onset, severity, symptoms, level of hopelessness, and the course of depression vary. Recurrent depression is common. All mothers must be screened during the sixth week postpartum at the latest. Screening alone is not

    Full Text Available Patients with bipolar disorder spend more time in a depressed than manic state, even with individualized treatment. To date, bipolar depression is often misdiagnosed and ineffectively managed both for acute episodes and residual symptoms. This review attempts to summarize the current status of available treatment strategies in the treatment of bipolar depression. For acute and prophylactic treatment, a substantial body of evidence supports the antidepressive efficacy of lithium for bipolar disorders and its antisuicidal effects. Among numerous anticonvulsants with mood-stabilizing properties, valproate and lamotrigine could be first-line options for bipolar depression. Due to receptor profile, mood-stabilizing properties of second-generation antipsychotics have been explored, and up to date, quetiapine and olanzapine appear to be a reasonable option for bipolar depression. The usefulness of antidepressants in bipolar depression is still controversial. Current guidelines generally recommend the cautious antidepressant use in combination with mood stabilizers to reduce the risk of mood elevation or cycle acceleration. Results from clinical trials on psychosocial intervention are promising, especially when integrated with pharmacotherapy. Most patients with bipolar depression need individualized and combined treatment, although the published evidence on this type of treatment strategy is limited. Future studies on the utility of currently available agents and modalities including psychosocial intervention are required.

  15. Current understanding of the bi-directional relationship of major depression with inflammation

    2012-02-01

    Full Text Available Abstract Consistent evidence links major depression and its affective components to negative health outcomes. Although the pathways of these effects are likely complex and multifactorial, recent evidence suggests that innate inflammatory processes may play a role. An overview of current literature suggests that pathways between negative moods and inflammation are bi-directional. Indeed, negative moods activate peripheral physiologic mechanisms that result in an up regulation of systemic levels of inflammation. Conversely, peripheral inflammatory mediators signal the brain to affect behavioral, affective and cognitive changes that are consistent with symptoms of major depressive disorder. It is likely that these pathways are part of a complex feedback loop that involves the nervous, endocrine, and immune systems and plays a role in the modulation of peripheral inflammatory responses to central and peripheral stimuli, in central responses to peripheral immune activation and in the maintenance of homeostatic balance. Further research is warranted to fully understand the role of central processes in this feedback loop, which likely contributes to the pathophysiology of mental and physical health.

    Full Text Available The aim of the study was to investigate the social cognitive functioning of participants with major depressive disorder when compared with healthy controls, and to assess the impact of symptom severity and affective and somatic symptom clusters on social cognition. One hundred and eight adult patients with depression (66 remitted and 42 current and 52 healthy controls were assessed using the Wechsler Advanced Clinical Solutions: Social Perception Subtest, measuring facial affect recognition in isolation and in combination with prosody and body language interpretation. While no associations between the diagnostic status (MDD vs controls and any of the social cognition measures were found, severity of depressive and anxious symptoms predicted performance on all social cognition subscales in currently depressed participants, controlling for age, gender, education and psychotropic medication. Moreover, in the current MDD group, an affective depressive symptom cluster was inversely related to performance on the more complex ACS Pairs and Prosody tasks, while a somatic symptom cluster was inversely related to ACS Affect Recognition and Total scores. In contrast, there were no associations between symptom severity or symptom clusters and the WAIS ACS in remitted depression participants. Given the state like nature social deficits in this study, these impairments may cause problems with day to day functioning and have implications in targeted therapeutic interventions.

    Cardiac conduction disorders are common diseases which cause slow heart rate and syncope. The best way to treat these diseases by now is to implant electronic pacemakers, which, yet, have many disadvantages, such as the limited battery life and infection. Biopacemaker has been expected to replace the electronic devices. Automatic ventricular myocytes (VMs) could show pacemaker activity, which was induced by depressing inward-rectifier K+ current (IK1). In this study, a 2D model of human biopacemaker was created from the ventricular endocardial myocytes. We examined the stability of the created biopacemaker and investigated its driving capability by finding the suitable size and spatial distribution of the pacemaker for robust pacing and driving the surrounding quiescent cardiomyocytes. Our results suggest that the rhythm of the pacemaker is similar to that of the single cell at final stable state. The driving force of the biopacemaker is closely related to the pattern of spatial distribution of the pacemaker. PMID:26998484

    The inflammation theory of depression, proposed over 20years ago, was influenced by early studies on T cell responses and since then has been a stimulus for numerous research projects aimed at understanding the relationship between immune function and depression. Observational studies have shown that indicators of immunity, especially C reactive protein and proinflammatory cytokines, such as interleukin 6, are associated with an increased risk of depressive disorders, although the evidence from randomized trials remains limited and only few studies have assessed the interplay between innate and adaptive immunity in depression. In this paper, we review current knowledge on the interactions between central and peripheral innate and adaptive immune molecules and the potential role of immune-related activation of microglia, inflammasomes and indoleamine-2,3-dioxygenase in the development of depressive symptoms. We highlight how combining basic immune methods with more advanced 'omics' technologies would help us to make progress in unravelling the complex associations between altered immune function and depressive disorders, in the identification of depression-specific biomarkers and in developing immunotherapeutic treatment strategies that take individual variability into account.

    Manic switch is a relevant issue when treating bipolar depression. Some risk factors have been suggested, but unequivocal findings are lacking. We therefore investigated predictors of switch from depression to mania in the Systematic Treatment Enhancement Program for Bipolar Disorder (STEP-BD) sample. Manic switch was defined as a depressive episode followed by a (hypo)manic or mixed episode within the following 12 weeks. We assessed possible predictors of switch using generalized linear mixed models (GLMM). 8403 episodes without switch and 512 episodes with switch (1720 subjects) were included in the analysis. Several baseline variables were associated with a higher risk of switch. They were younger age, previous history of: rapid cycling, severe manic symptoms, suicide attempts, amphetamine use and some pharmacological and psychotherapeutic treatments. During the current depressive episode, the identified risk factors were: any possible mood elevation, multiple mania-associated symptoms with at least moderate severity, and comorbid panic attacks. In conclusion, our study suggests that both characteristics of the disease history and clinical features of the current depressive episode may be risk factors for manic switch.

    The authors tested the cognitive vulnerability hypotheses of depression with a retrospective behavioral high-risk design. Individuals without current Axis I diagnoses who exhibited either negative or positive cognitive styles were compared on lifetime prevalence of depressive and other disorders and the clinical parameters of depressive episodes. Consistent with predictions, cognitively high-risk participants had higher lifetime prevalence than low-risk participants of major and hopelessness depression and marginally higher prevalence of minor depression. These group differences were specific to depressive disorders. The high-risk group also had more severe depressions than the low-risk group, but not longer duration or earlier onset depressions. The risk group differences in prevalence of depressive disorders were not mediated by current depressive symptoms.

    Full Text Available In the last two decades, different research has demonstrated the high prevalence of childhood trauma, including sexual abuse, among depressive women. These findings are associated with a complex, severe, and chronic psychopathology. This can be explained considering the neurobiological changes secondary to early trauma that can provoke a neuroendocrine failure to compensate in response to challenge. It suggests the existence of a distinguishable clinical-neurobiological subtype of depression as a function of childhood trauma that requires specific treatments. Among women with depression and early trauma receiving treatment in a public mental health service in Chile, it was demonstrated that a brief outpatient intervention (that screened for and focused on childhood trauma and helped patients to understand current psychosocial difficulties as a repetition of past trauma was effective in reducing psychiatric symptoms and improving interpersonal relationships. However, in this population, this intervention did not prevent posttraumatic stress disorder secondary to the extreme earthquake that occurred in February 2010. Therefore in adults with depression and early trauma, it is necessary to evaluate prolonged multimodal treatments that integrate pharmacotherapy, social support, and interpersonal psychotherapies with trauma focused interventions (specific interventions for specific traumas.

    We designed this study to investigate the modulating effects of duloxetine on symptoms and grey matter of patients with major depressive disorder combined with panic disorder. We also aimed to discover if there was any persistence of grey-matter deficits after remission and to find 'trait markers' for this comorbidity. High-resolution magnetic resonance imaging and voxel-based morphometric measurements were performed on 15 patients at baseline and remitted status (week 6) compared to 15 healthy control subjects who were scanned twice within 6 wk. The rating scales of depressive and panic symptoms improved with statistical significance (corrected pgrey-matter deficits in infero-frontal, limbic, occipital, temporo-parietal, cerebellar areas (trait marker regions) in drug-naive patients were observed compared to controls at baseline (family-wise error corrected pgrey matter in healthy controls over the 6-wk period. Duloxetine-induced increases of grey matter were very subtle in left infero-frontal cortex, right fusiform gyrus, and right cerebellum VIIIa areas (state marker regions) after 6-wk therapy (uncorrected pgrey matter to the level of control subjects and grey-matter deficits in patients appear largely unaffected by duloxetine. We suggest that short-term duloxetine therapy improved the clinical symptoms of patients with major depressive disorder combined with panic disorder. These improvements might be related to a modest increase of grey matter in state marker regions of the brain. The deficits of trait marker regions were more evident and are likely to be important for pathogenesis.

    Rumination has consistently been found to be associated with the onset and duration of major depressive episodes. Little research, however, has examined factors that may weaken the association between maladaptive coping, such as rumination, and depressive symptoms. In three samples of participants, including 149 never-depressed adolescent girls, 41 never-depressed women, and 39 depressed women, we examined whether generally adaptive forms of coping interacted with generally maladaptive coping to predict depressive symptoms. Age-appropriate measures of coping and depression were administered to participants in each sample. In never-depressed females, maladaptive coping / rumination were more strongly related to depressive symptoms in the presence of lower levels of adaptive coping. The relation between depression and maladaptive coping / rumination was weaker in the context of higher levels of adaptive coping. In contrast, for the depressed females, we found main effects for rumination and adaptive coping, with higher levels of rumination and lower levels of adaptive coping being associated with higher levels of depressive symptoms. The present findings highlight how adaptive coping and maladaptive coping, including rumination, differentially relate to each other and depressive symptoms depending on individuals’ current depressive state.

    As part of the Episodic Response Project (ERP), we intensively monitored discharge and stream chemistry of 13 streams located in the Northern Appalachian region of Pennsylvania and in the Catskill and Adirondack Mountains of New York from fall 1988 to spring 1990. The ERP clearly documented the occurrence of acidic episodes with minimum episodic pH ??? 5 and inorganic monomeric Al (Alim) concentrations >150 ??g/L in at least two study streams in each region. Several streams consistently experienced episodes with maximum Alim concentrations >350 ??g/L. Acid neutralizing capacity (ANC) depressions resulted from complex interactions of multiple ions. Base cation decreases often made the most important contributions to ANC depressions during episodes. Organic acid pulses were also important contributors to ANC depressions in the Adirondack streams, and to a lesser extent, in the Catskill and Pennsylvania streams. Nitrate concentrations were low in the Pennsylvania streams, whereas the Catskill and Adirondack study streams had high NO3- concentrations and large episodic pulses (???54 ??eq/L). Most of the Pennsylvania study streams also frequently experienced episodic pulses of SO42- (???78 ??eq/L), whereas the Adirondack and Catskill streams did not. High baseline concentrations of SO42- (all three study areas) and NO3- (Adirondacks and Catskills) reduced episodic minimum ANC, even when these ions did not change during episodes. The ion changes that controlled the most severe episodes (lowest minimum episodic ANC) differed from the ion changes most important to smaller, more frequent episodes. Pulses of NO3- (Catskills and Adirondacks), SO42- (Pennsylvania), or organic acids became more important during major episodes. Overall, the behavior of streamwater SO42- and NO4- is an indicator that acidic deposition has contributed to the severity of episodes in the study streams.

    Full Text Available OBJECTIVE: Post-stroke major depressive episode is very frequent, but underdiagnosed. Researchers have investigated major depressive episode symptomatology, which may increase its detection. This study was developed to identify the depressive symptoms that better differentiate post-stroke patients with major depressive episode from those without major depressive episode. METHOD: We screened 260 consecutive ischemic stroke patients admitted to the neurology clinic of a university hospital. Seventy-three patients were eligible and prospectively evaluated. We assessed the diagnosis of major depressive episode using the Structured Clinical Interview for DSM-IV and the profile of depressive symptoms using the 31-item version of the Hamilton Depression Rating Scale. For data analysis we used cluster analyses and logistic regression equations. RESULTS: Twenty-one (28.8% patients had a major depressive episode. The odds ratio of being diagnosed with major depressive episode was 3.86; (95% CI, 1.23-12.04 for an increase of one unit in the cluster composed by the domains of fatigue/interest and retardation, and 2.39 (95% CI, 1.21-4.71 for an increase of one unit in the cluster composed by the domains of cognitive, accessory and anxiety symptoms. The domains of eating/weight and insomnia did not contribute for the major depressive episode diagnosis. CONCLUSION: The domains of retardation and interest/fatigue are the most relevant for the diagnosis of major depressive episode after stroke.OBJETIVO: O episódio depressivo maior após acidente vascular cerebral é muito frequente, mas é subdiagnosticado.

    Factors contributing to treatment-emergent suicidal ideation (TESI) using antidepressants have been in the focus of recent research strategies. We investigated previously established clinical predictors of TESI and combined these with several polymorphisms of candidate genes in patients with major depressive disorder. Common polymorphisms involved in the tryptophan hydroxylase 1 (TPH1) and 2 (TPH2), serotonin transporter, monoamine oxidase A (MAOA) and brain-derived neurotrophic factor (BDNF) were investigated in a naturalistic inpatient study of the German research network on depression. We compared patients showing TESI with non-TESI suicidal patients and with non-suicidal patients using univariate tests to detect relevant factors, which were further tested in logistic regression and CART (Classification and Regression Trees) analyses. Of the 269 patients, TESI occurred in 22 patients (17 female), 117 patients were defined as non-TESI suicidal patients, and 130 patients were classified as non-suicidal. When comparing cases with both control groups we found the TPH2 rs1386494 (C/T) polymorphism to be moderately associated with TESI (Univariate tests: TESI vs. non-suicidality: p=0.005; adjusted: p=0.09; TESI vs. non-TESI suicidal patients: p=0.0024; adjusted: p=0.086). This polymorphism remained the only significant genetic factor in addition to clinical predictors in logistic regression and CART analyses. CART analyses suggested interactions with several clinical predictors. Haplotype analyses further supported a contribution of this polymorphism in TESI. The TPH2 rs1386494 (C/T) polymorphism might contribute to the genetic background of TESI. This polymorphism has been previously associated with committed suicide and major depressive disorder. The small number of cases warrants replication in larger patient samples. Lack of a placebo control group hampers definite conclusions on an association with antidepressive treatment.

    Late life depression is a complex disease associated with a number of contributing neurobiological factors, including cerebrovascular disease, neurodegeneration, and inflammation, which also contribute to its longitudinal prognosis and course. These factors create a context in which the brain is more vulnerable to the impact of stress, and thus, to depression. At the same time, some individuals are protected from late life depression and its consequences, even in the face of neurobiological vulnerability, through benefitting from one or more attributes associated with resilience, including social support, engagement in physical and cognitive activities, and brain reserve. Enhanced understanding of how neurobiological and environmental factors interact in predicting vulnerability and resilience is needed to predict onset and course of depression in late life and develop more effective interventions.

    Age-related macular degeneration (AMD) - despite advances in prevention and medical treatment options - remains prevalent among older adults, often resulting in functional losses that negatively affect the mental health of older adults. In particular, the prevalence of both anxiety and depression in patients with AMD is high. Along with medical treatment options, low vision rehabilitation and AMD-specific behavioral and self-management programs have been developed and have demonstrated effectiveness in improving the mental health of AMD patients. This article reviews the prevalence of anxiety and depression in patients with advanced AMD, discusses potential mechanisms accounting for the development of depression and anxiety in AMD patients, presents the state-of the-art of available interventions for addressing anxiety and depression in AMD patients, and delineates recommendations for eye care professionals regarding how to screen for these two prevalent mental health problems and how to facilitate appropriate treatment for patients with AMD.

    The current study aimed to investigate the interaction between the serotonin 1A receptor gene (HTR1A) C-1019G polymorphism and recent negative life stressors on depression in a Korean community sample. The HTR1A C-1019G polymorphism was genotyped in 416 community-dwelling Koreans (156 males, 260 females; 44.37 ± 14.67 years old). Lifetime and current major depressive episodes were diagnosed using the Structured Clinical Interview for DSM-IV. The Center for Epidemiological Studies for Depression Scale (CES-D) was self-applied and face-to-face interviews investigating negative life stressors within the last 6 months were also performed. The results indicated that there were significant interactions between the C-1019G polymorphism and negative life stressors on CES-D scores (p = 0.02) as well as on current major depressive episodes (p = 0.002), but not on past major depressive episodes. G carriers alone had higher CES-D scores and more frequently experienced major depressive episodes after stressors. The interaction between the C-1019G polymorphism in HTR1A and recent negative life stressors accounted for current major depressive episodes and depressive symptoms. Our findings suggest that people with this gene variant may be more susceptible to developing depression especially after negative life stressors. Copyright © 2011 S. Karger AG, Basel.

    2011-05-01

    Episodic ataxia (EA) designates a group of autosomal dominant channelopathies that manifest as paroxysmal attacks of imbalance and incoordination. EA conditions are clinically and genetically heterogeneous. Seven types of EA have been reported so far but the majority of clinical cases result from two recognized entities. Episodic ataxia type 1 (EA1) is characterized by brief episodes of ataxia and dysarthria, and interictal myokymia. Onset occurs during the first two decades of life. Associated epilepsy has been reported in some EA1 patients. EA1 is caused by mutations of the KCNA1 gene coding for the voltage-gated potassium channel Kv1.1. Mutation is mostly missense mutations. Acetazolamide, a carbonic-anhydrase inhibitor, may reduce the frequency and severity of the attacks in some but not all affected individuals. Episodic ataxia type 2 (EA2) is characterized by episodes lasting longer than in EA1, that manifest by ataxia, dysarthria, vertigo, and also, in most of the cases, an interictal nystagmus. Other clinical features as developmental delay or epilepsy can be present in some patients. Brain MRI shows frequently a vermian atrophy. Onset occurs typically in childhood or early adolescence, but can sometimes be in adulthood. EA2 is caused by mutations in CACNA1A, a gene coding for the neuronal voltage-gated calcium channel Cav1.1. For two-thirds of the cases, mutations lead to a stop codon. This type is most often responsive to acetazolamide that reduces the frequency and severity of attacks, but does not appear to prevent the progression of interictal symptoms. This article summarizes current knowledge on episodic ataxia type 1 and 2 and describes briefly the other types of EA. Molecular analysis of KCNA1 or CACNA1A provides a confirmation of the diagnosis of EA1 and EA2. Other types remain rare phenotypic variants. Among them, only two genes have been identified: CACNB4 in EA5 and SLC1A3 in EA6 and mutations have been found in a very few cases. No mutation

    Pharmacological treatment of acute anxiety still relies on benzodiazepines, while chronic anxiety disorders and depression are treated with different antidepressants, according to specific indications. The monoaminergic axis is represented by two families which are being developed: (i) serotonin-norepinephrine-dopamine reuptake inhibitors (SNDRI), also called triple reuptake inhibitors (TRI), for the treatment of depression (amitifadine), (ii) multimodal antidepressants for depression and anxiety disorders (generalized anxiety disorder mainly) (tedatioxetine, vortioxetine and vilazodone). Third-generation antipsychotics (aripiprazole, lurasidone, brexpiprazole, cariprazine) appear relevant in the treatment of resistant depression and some anxiety disorders. Among the modulators of the glutamatergic axis, promising compounds include: (i) ionotropic regulators of NMDA receptors: esketamine, AVP-923 and AVP-786, CERC-301, rapastinel (Glyx-13), NRX-1074 developed for depression, rapastinel and bitopertine developed for obsessive compulsive disorder, (ii) metabotropic glutamate receptors modulators: decoglurant and basimglurant developed for depression and mavoglurant developed for obsessive compulsive disorder.

    There is substantial recent interest in the role of oxytocin in social and affiliative behaviors-animal models of depression have suggested a link between oxytocin and mood. We reviewed literature to date for evidence of a potential relationship between peripheral oxytocin concentration and depressive symptoms in humans. Pubmed(®) and PsychINFO(®) were searched for biomedical and social sciences literature from 1960 to May 19, 2015 for empirical articles in English involving human subjects focused on the relationship between peripheral oxytocin concentration and depressive symptoms, excluding articles on the oxytocin receptor gene, or involving exogenous (i.e. intranasal) administration of oxytocin. Eight studies meeting criteria were identified and formally reviewed. Studies of pregnant women suggested an inverse relationship between oxytocin level and depressive symptom severity. Findings in nonpregnant women were broadly consistent with the role of oxytocin release in response to stress supported by animal studies. The relationship between oxytocin and depression in men appeared to be in the opposite direction, possibly reflecting the influence of gonadal hormones on oxytocinergic functioning found in other mammalian species. Overall, small sample sizes, heterogeneity in study designs, and other methodological limitations may account for inconsistent findings. Future research utilizing reliable oxytocin measurement protocols including measurements across time, larger sample sizes, and sample homogeneity with respect to multiple possible confounders (age, gender, race and ethnicity, ovarian status among women, and psychosocial context) are needed to elucidate the role of oxytocin in the pathogenesis of depression, and could guide the design of novel pharmacologic agents.

    Newborn neurons are continuously added to the adult hippocampus. Early studies found that adult neurogenesis is impaired in models of depression and anxiety and accelerated by antidepressant treatment. This led to the theory that depression results from impaired adult neurogenesis and restoration of adult neurogenesis leads to recovery. Follow up studies yielded a complex body of often inconsistent results, and the veracity of this theory is uncertain. We propose five criteria for acceptance of this theory, we review the recent evidence for each criterion, and we draw the following conclusions: Diverse animal models of depression and anxiety have impaired neurogenesis. Neurogenesis is consistently boosted by antidepressants in animal models only when animals are stressed. Ablation of neurogenesis in animal models impairs cognitive functions relevant to depression, but only a minority of studies find that ablation causes depression or anxiety. Recent human neuroimaging and postmortem studies are consistent with the neurogenic theory, but they are indirect. Finally, a novel drug developed based on the neurogenic theory is promising in animal models.

    Objective To explore the functional laterality between left and right hemisphere on visuo-spatial cognitive function in first-episode depressive disorder patients. Methods A total of 35 depressive disorder patients ( experiment group ) and 36 normal healthy subjects ( control group ) were tested to make visuo-spatial rotation tasks by the event-related potential system, and the change of the brain distribution topographic map was observed. Results ①Compared with control group,the mean error rate [ ( 22. 3 ±6. 5 )% vs ( 18. 4 ± 5. 6 )% ] and the mean response time [ ( 761. 4 ± 94. 2 )ms vs ( 634.7 ± 84. 9 )ms ] significantly increased in depressive disorder group ( P <0. 05 ). ②Compared with control group,the normal P500 volatility at P4 was significantly decreased in depressive disorder group [ ( 7. 63 ±2. 63 )μV vs ( 9. 58 ±3. 22 )μV,P <0. 05 ],and the mirror P500 volatility at P4 was significantly increased[ ( 6. 90 ± 1. 92 )ΜV VS ( 4. 95 ± 1. 92 )μV ,P < 0. 05 ]. In P500, the self mirror-normal difference of excitability disappeared in depressive disorder group. The normal excitability in the right parietal-occipital lobe was significantly higher than that in the left parietal-occipital lobe ( P <0. 05 ),but the mirror excitement difference disappeared in depressive disorder group ( P >0. 05 ). The normal and mirror excitement in the right parietal-occipital lobe were both significantly higher than those in the left in control group ( P <0. 05 ). Conclusion The visuo-spatial cognitive function is impaired in patients with first-episode depression for both normal oriented images and mirror images. The functional laterality is found in normal images for visuo-spatial rotation,but not in mirror images. Specific topographic characteristics of EEG during visuo-spatial rotation tasks are potential biomarkers for first-episode depressive disorder.%目的 探讨首发抑郁症患者视觉空间认知的左右大脑

    Objective: The paper aimed to study characteristics and influencing factors of the visual spatial working memory of the patients with the first-episode depression. Methods: 30 first-episode depression patients and 30 normal controls were measured by Hamilton Depression Scale (HAMD), neuropsychological testing and the spatial working memory test. Results: The experimental group and control group has no difference in terms of base memory (P> 0.05). Visual spatial working memory of the first-episode patients was significantly damaged (P= 0.035), while their location memory relatively Temained(P= 0.518). Degree of depression has relevance to the damage degree of both visual spatial working memory and distance memory (r =- 0.272, P = 0.036; r =- 0.323, P= 0.012), while it has no relevance to the damage degree of position memory (r=-0.083,P = 0.572). Visual spatial working memory is influenced by gender and education level (P = 0.011, p = 0.298; P = 0.000, p = 0.536), but not by age (P= 0.345, P = 0.129), among which education level has a greater impact on the distance memory (P = 0.000, P = 0.568) while gender and educational level has impact on position memory (P = 0.029, p = 0.263; P = 0.001,p = 0.484). Conclusion; The distance memory of patients with first-episode depression is damaged, while their location memory relatively remained. The damage degree of the distance working memory has relevance to the degree of depression. It can be predicted that the process of the visual spatial distance working memory and visual spatial location working memory may have applied different neural circuits.%目的:探究首发抑郁症患者的视空间工作记忆特点及影响因素.方法:收集首发抑郁症患者、健康对照者各30例,分别进行汉密尔顿抑郁量表的评估、神经心理背景测试和视空间工作记忆测试.结果:实验组和对照组的基础记忆水平差异没有统计学意义(P>0.05).抑郁患者视空间距

    The past decade has witnessed a resurgence of interest in behavioral interventions for depression. This contemporary work is grounded in the work of Lewinsohn and colleagues, which laid a foundation for future clinical practice and science. This review thus summarizes the origins of a behavioral model of depression and the behavioral activation (BA) approach to the treatment and prevention of depression. We highlight the formative initial work by Lewinsohn and colleagues, the evolution of this work, and related contemporary research initiatives, such as that led by Jacobson and colleagues. We examine the diverse ways in which BA has been investigated over time and its emerging application to a broad range of populations and problems. We close with reflections on important directions for future inquiry.

    Abstract Objectives. The aim of this study was to compare efficacy of antidepressant monotherapies and combinations of antidepressants in the treatment of resistant patients in current clinical practice. Methods. We reviewed chart documents of resistant depressive inpatients treated at least 4 weeks with a new treatment. Depressive symptoms and clinical status were assessed using Montgomery and Åsberg Depression Rating Scale (MADRS), Beck Depression Inventory-Short Form and Clinical Global Impression at the baseline, week 2 and in the end of treatment. Results. We identified 81 patients (27 with combinations and 51 with monotherapies) that were suitable for analyses. The combination group achieved higher reduction of MADRS score (14.6 vs 10.2 pts., p=0.02) and response rate (≥ 50% reduction of MADRS, 67% vs 39%, p=0.03). Number needed to treat for response was 4. Conclusions. Based on our results, we suggest that combination of antidepressants might be more effective than monotherapy in clinical practice.

    The neurotrophic hypothesis of depression states that the major depressive episode is associated with lower neurotrophic factors levels, which increase with amelioration of depressive symptoms. However, this hypothesis has not been extended to investigate neurotrophic factors other than the brain-derived neurotrophic factor (BDNF). We therefore explored whether plasma levels of neurotrophins 3 (NT-3) and 4 (NT-4), nerve growth factor (NGF) and glial cell line derived neurotrophic factor (GDNF) changed after antidepressant treatment and correlated with treatment response. Seventy-three patients with moderate-to-severe, antidepressant-free unipolar depression were assigned to a pharmacological (sertraline) and a non-pharmacological (transcranial direct current stimulation, tDCS) intervention in a randomized, 2 × 2, placebo-controlled design. The plasma levels of NT-3, NT-4, NGF and GDNF were determined by enzyme-linked immunosorbent assay before and after a 6-week treatment course and analyzed according to clinical response and allocation group. We found that tDCS and sertraline (separately and combined) produced significant improvement in depressive symptoms. Plasma levels of all neurotrophic factors were similar across groups at baseline and remained significantly unchanged regardless of the intervention and of clinical response. Also, baseline plasma levels were not associated with clinical response. To conclude, in this 6-week placebo-controlled trial, NT-3, NT-4, NGF and GDNF plasma levels did not significantly change with sertraline or tDCS. These data suggest that these neurotrophic factors are not surrogate biomarkers of treatment response or involved in the antidepressant mechanisms of tDCS.

    Results from studies using a behavioral high-risk design and approximations to it generally have corroborated the cognitive vulnerability hypothesis of depression, whereas results from remitted depression studies typically have not. Suspecting that design features of previously conducted remitted designs likely precluded them from detecting maladaptive cognitive patterns, the authors conducted a study featuring the remitted design that has been successful in studies of a biological vulnerability for depression. Participants' current depressive symptoms, negative cognitive styles (hopelessness theory), dysfunctional attitudes (Beck's theory), and lifetime prevalence of clinically significant depression were assessed. Participants who had remitted from an episode of clinically significant depression had more negative cognitive styles, but not greater levels of dysfunctional attitudes, than did never depressed individuals.

    Decreased heart rate variability (HRV) is a cardiovascular predictor of mortality. Recent debate has focused on whether reductions in HRV in major depressive disorder (MDD) are a consequence of the disorder or a consequence of pharmacotherapy. Here we report on the impact of transcranial direct current stimulation (tDCS), a non-pharmacological intervention, vs. sertraline to further investigate this issue. The employed design was a double-blind, randomized, factorial, placebo-controlled trial. One hundred and eighteen moderate-to-severe, medication-free, low-cardiovascular risk depressed patients were recruited for this study and allocated to either active/sham tDCS (10 consecutive sessions plus two extra sessions every other week) or placebo/sertraline (50 mg/d) for 6 wk. Patients were age and gender-matched to healthy controls from a concurrent cohort study [the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)]. The impact of disorder, treatment and clinical response on HRV (root mean square of successive differences and high frequency) was examined. Our findings confirmed that patients displayed decreased HRV relative to controls. Furthermore, HRV scores did not change following treatment with either a non-pharmacological (tDCS) or pharmacological (sertraline) intervention, nor did HRV increase with clinical response to treatment. Based on these findings, we discuss whether reduced HRV is a trait-marker for MDD, which may predispose patients to a host of conditions and disease even after response to treatment. Our findings have important implications for our understanding of depression pathophysiology and the relationship between MDD, cardiovascular disorders and mortality.

    Aphasia is a common consequence of stroke; it is estimated that about two-thirds of aphasic patients will develop depression in the first year after the stroke. Treatment of post-stroke depression (PSD) is challenging due to the adverse effects of pharmacotherapy and difficulties in evaluating clinical outcomes, including aphasia. Transcranial direct current stimulation (tDCS) is a novel treatment that may improve clinical outcomes in the traditionally pharmacotherapy-refractory PSD. Our aim was to evaluate the safety and efficacy of tDCS for patients with PSD and with aphasia. The Stroke Aphasic Depression Questionnaire (SADQ) and the Aphasic Depression Rating Scale (ADRS) were used to evaluate the severity of PSD. The diagnoses of PSD and aphasia were confirmed by a psychiatrist and a speech-language pathologist, respectively. In this open case series, patients (n = 4) received 10 sessions (once a day) of bilateral tDCS to the dorsolateral prefrontal cortex (DLPFC) and two additional sessions after two and four weeks, for a total of 12 sessions. All patients exhibited improvement in depression after tDCS, as indicated by a decrease in SADQ (47.5%) and in ADRS (65.7%). This improvement was maintained four weeks after the treatment. In this preliminary, open-label study conducted in four PSD patients with aphasia, bilateral tDCS over the DLPFC was shown to induce a substantial mood improvement; tDCS was safe and well tolerated by every patient. Stroke patients with aphasia can be safely treated for PSD with tDCS. Sham-controlled studies are necessary to evaluate this technique further.

    Full Text Available Background and Objectives: Negative symptoms emerge in many patients with psychotic disorders long before the onset of the acute illness. These symptoms are often impossible to differentiate from certain Cluster A personality traits. Methods: The current study examines the extent to which premorbid negative symptoms are contributing factors to the development of primary and secondary negative symptomatology. Participants were 84 neuroleptic-naïve patients experiencing the occurrence of their first acute psychotic episode. Symptoms of psychopathology were assessed at two points: at admission and after remission of the acute episode. The Spanish version of the PANSS scale was administered. Premorbid personality assessment was considered as a proxy measure to evaluate each participant's negative symptomatology prior to the onset of the illness. Potential causes of secondary negative symptomatology, such as depression and extrapyramidal symptoms, were also examined. Results: 'Non-respondent' or 'residual' negative symptoms at discharge were significantly predicted by primary negative symptoms. To a lesser extent, disorganization and depressive symptoms at discharge and the Schizoid dimension of premorbid personality predicted residual negative symptoms. Conclusions: The severity of negative symptoms at the onset of the psychotic episode varied across patients. After controlling for 'respondent' and 'non-respondent' primary negative symptoms and other potential causes of negative symptoms, premorbid negative symptoms had a slight, but significant predictive relationship with residual negative symptoms.

    2010-01-01

    We previously reported a novelty P3 reduction in depressed patients compared to healthy controls (n=20 per group) in a novelty oddball task using a 31-channel montage. In an independent replication and extension using a 67-channel montage (n=49 per group), reference-free current source density (CSD) waveforms were simplified and quantified by a temporal, covariance-based principal components analysis (PCA) (unrestricted Varimax rotation), yielding factor solutions consistent with other oddball tasks. A factor with a loadings peak at 343 ms summarized the target P3b source as well as a secondary midline frontocentral source for novels and targets. An earlier novelty vertex source (NVS) at 241 ms was present for novels, but not targets, and was reduced in patients. Compatible CSD-PCA findings were also confirmed for the original low-density sample. Results are consistent with a reduced novelty response in clinical depression, involving the early phase of the frontocentral novelty P3.

    Objective: To explore the effect of self-help intervention based on Cognitive Behavioral Therapy on depressive symptoms and mental health status of ifrst-episode depression outpatients. Methods: We randomly divided 126 ifrst-episode depression outpatients from two tertiary hospitals in Changsha into the no-guided experimental group (n=42) ,the guided experimental group (n=42) and the control group (n=42). During and after the intervention, 25 subjects were lost to follow-up, Finally, there were 39 subjects in the no-guided experimental group, 32 in the guided experimental group and 30 in the control group. An antidepressant skills workbook was provided for each patient in the non-guided experimental group, besides, one telephone guidence every two weeks was provided for each patient in the guided experimental group, while no speciifc training was supplied to the control group. We evaluated all subjects with Beck Depression Inventory (BDI) and 10-item Kessler Scale (K10) before the self-help intervention and 2 months after the intervention. Results: After the intervention, the scores of both BDI and K10 in three groups decreased signiifcantly (P0.05). Conclusions: The cognitive behavioral self-help intervention by self-help manual could not effectively improve depressive symptoms and mental health status of ifrst-episode depression outpatients. We suggest that intensity of intervention should be strengthened in future study.%目的:评价基于认知行为疗法的自助干预对改善门诊首发抑郁症患者抑郁症状与心理健康水平的效果。方法:将126名门诊首发抑郁症患者随机分成无指导的干预组(n=42)、有指导的干预组(n=42)和对照组(n=42),干预中及干预结束后共失访25人,最终入组的无指导的干预组39人,有指导的干预组32人,对照组30人。无指导的干预组接受自助手册形式的自助干预,有指导的干预组接受自助手册加上电话形式的自助干预,对照

Mood disorders, as defined by the World Mental Health and the Diagnostic and Statistical Manual of Mental Disorders, 4th edition, have a 12-month prevalence which varies from 3% in Japan to over 9% in the US. A recent American survey found the prevalence of current depression to be 9% and the rate of current major depression to be 3.4%. All studies of depressive disorders have stressed the importance of the mortality and morbidity associated with depression. The mortality risk for suicide in depressed patients is more than 20-fold greater than in the general population. Recent studies have also shown the importance of depression as a risk factor for cardiovascular death. The risk of cardiac mortality after an initial myocardial infarction is greater in patients with depression and related to the severity of the depressive episode. Greater severity of depressive symptoms has been found to be associated with significantly higher risk of all-cause mortality including cardiovascular death and stroke. In addition to mortality, functional impairment and disability associated with depression have been consistently reported. Depression increases the risk of decreased workplace productivity and absenteeism resulting in lowered income or unemployment. Absenteeism and presenteeism (being physically present at work but functioning suboptimally have been estimated to result in a loss of $36.6 billion per year in the US.

    Research on sensorial interactions with psychiatric diseases and particularly with the depressive syndrome has mainly focused on visual or auditory processes and much less on olfaction. The depressive illness is one of the most frequent psychiatric diagnoses in the community, with approximately one in five women and one in eight men experiencing a major depressive episode during their lifetime. Although genetic, epigenetic, neuroanatomical, neurochemical, neuroendocrinological and neuroimmunological changes can be detected during depression, the etiology of depression remains partly unclear. The current explanatory models are based on two main factors, i.e. pharmacological dysfunctions and stress effects. In this way and because of strong connections between olfactory pathways and cerebral areas implied in mood regulation and emotions (i.e. the limbic system and prefrontal areas), the interactions between olfaction and depression could constitute a relevant way of research at three different levels. First, olfactory dysfunction observed in depression could serve the diagnosis and contribute to a better understanding of mechanisms implied in thymic pathologies. Published papers show a decrease of olfactory sensitivity in major depression which does not occur in bipolar or saisonal depression. Second, it has been shown that olfactory deficits could induce depressive symptoms. In this context, an animal model (olfactory bulbectomized rat) reinforces the hypothesis of the important role of olfaction in depression based on neuroanatomical and neurochemical observations. Third, several publications have demonstrated that odors can positively impact the depressive mood. Thus, a remediation by odors in depression appears to be a promising way. From several decades, the olfaction/depression interactions have been covered by a broad literature. Thus, the present review will not propose an exhaustive examination but aims to point out the most recently published papers and

    Full Text Available Severe regional haze pollution events occurred in eastern and central China in January 2013, which had adverse effects on the environment and public health. Extremely high levels of particulate matter with aerodynamic diameter of 2.5 μm or less (PM2.5 with dominant components of sulfate and nitrate are responsible for the haze pollution. Although heterogeneous chemistry is thought to play an important role in the production of sulfate and nitrate during haze episodes, few studies have comprehensively evaluated the effect of heterogeneous chemistry on haze formation in China by using the 3-D models due to of a lack of treatments for heterogeneous reactions in most climate and chemical transport models. In this work, the offline-coupled WRF-CMAQ model with newly added heterogeneous reactions is applied to East Asia to evaluate the impacts of heterogeneous chemistry and the meteorological anomaly during January 2013 on regional haze formation. The revised CMAQ with heterogeneous chemistry not only captures the magnitude and temporal variation of sulfate and nitrate, but also reproduces the enhancement of relative contribution of sulfate and nitrate to PM2.5 mass from clean days to polluted haze days. These results indicate the significant role of heterogeneous chemistry in regional haze formation and improve the understanding of the haze formation mechanisms during the January 2013 episode.

    Response styles theory of depression postulates that rumination is a central factor in occurrence, severity and maintaining of depression. High neuroticism has been associated with tendency to ruminate. We investigated associations of response styles and neuroticism with severity and chronicity of depression in a primary care cohort study. In the Vantaa Primary Care Depression Study, a stratified random sample of 1119 adult patients was screened for depression using the Prime-MD. Depressive and comorbid psychiatric disorders were diagnosed using SCID-I/P and SCID-II interviews. Of the 137 patients with depressive disorders, 82% completed the prospective five-year follow-up with a graphic life chart enabling evaluation of the longitudinal course of episodes. Neuroticism was measured with the Eysenck Personality Inventory (EPI-Q). Response styles were investigated at five years using the Response Styles Questionnaire (RSQ-43). At five years, rumination correlated significantly with scores of Hamilton Depression Rating Scale (r=0.54), Beck Depression Inventory (r=0.61), Beck Anxiety Inventory (r=0.50), Beck Hopelessness Scale (r=0.51) and Neuroticism (r=0.58). Rumination correlated also with proportion of follow-up time spent depressed (r=0.38). In multivariate regression, high rumination was significantly predicted by current depressive symptoms and neuroticism, but not by anxiety symptoms or preceding duration of depressive episodes. Among primary care patients with depression, rumination correlated with current severity of depressive symptoms, but the association with preceding episode duration remained uncertain. The association between neuroticism and rumination was strong. The findings are consistent with rumination as a state-related phenomenon, which is also strongly intertwined with traits predisposing to depression. Copyright © 2015 Elsevier Masson SAS.

    The Ruminative Responses Scale, a measure of depressive rumination, contains two subscales: Brooding and Reflection. Treynor, Gonzalez, and Nolen-Hoeksema (2003) proposed that Brooding is maladaptive and Reflection is adaptive. This article examined the relationships among Brooding, Reflection, and previous depression in two samples of Japanese undergraduates, who were non-depressed at the time of their participation. Based on answers to a self-report measure, participants were divided into a formerly depressed group, who had experienced an episode that met the criteria for major depression, and a never-depressed group. Logistic regression analyses were conducted with Brooding, Reflection, and current depression as the independent variables and past depression as the dependent variable. Brooding had consistent positive associations with past depression. The relationship between Reflection and past depression was not significant for one sample, but was statistically significant and positive in the second sample. In the second sample, Brooding and Reflection both were related with past depression after controlling for worry.

    Full Text Available History should prevent us from repeating the mistakes of the past. This article focuses on the analysis and interpretation of the branding and promotion events that occurred during the Great Depression (1929-1933, projected on the decision of the marketing and management specialists of our times. The economic manifestations, such as: the unemployment rate, the decrease of the purchasing power, the crediting related difficulties, etc., specific to both periods of recession, revolve around the consumer and the way he modifies his consumer behavior. This paper tries to find an answer to the following question: given the decisions made by the managers in the 30’s, what brand strategies are recommended for this period? The answers to the question above are the object of the conclusions of this article. The recommendations provided herein invite us to meditate upon the depression from the previous century and to take a critical look at various marketing related attitudes, such as the disregard for rebranding or brand creation and the diminution of the promotion budgets.

    Male drinkers (n = 45) were asked to rate their desire for a drink of alcohol when presented with the sight, smell and taste of their preferred alcoholic beverage and of a lemon cordial drink. The subjects' level of depressed affect on that day and their average daily consumption of alcohol over the last 30 days were measured prior to exposure to these cues. Both level of depressed affect and log of mean daily alcohol consumption predicted increased desire for alcohol when alcohol cues were present, accounting for 40% of the variance in desire. When presented with the lemon cordial cues only 14% of the variance in desire for alcohol was explained by these variables. Also, Spearman's rank order correlations were calculated between heavy drinkers' (n = 19) ratings of self-efficacy to resist drinking and desire for alcohol in the presence of the alcohol cues. There were significant negative correlations between desire for alcohol and self-efficacy ratings on the 'urges and temptations' and 'positive social situations' subscales of the Situational Confidence Questionnaire-39. Several alternative accounts of these findings are discussed.

    Objective To explore the effects of sertraline on cognitive function in first-episode adolescent depression and some related factors of cognitive function. Methods Twenty-one adolescents with first-episode depression were recruited and given sertraline treatment for 6 weeks, and 21 healthy adolescents were involved as controls. Children's depression inventory(CDI) were evaluated at the baseline and the end point of treatment. A series of neuropsychological tests including Wisconsin card sorting test (WCST), wpatial working tnemory(SWM), stockings of Cambridge(SOC), intra-dimensional/ extra-dimensional shifts(IED) and delayed matching to sample (DMS)were performed twice to evaluate cognitive function. Results The patients had significant improvement in WCST and IED after sertraline treatment (P< 0.01). There was no obvious improvement on SWM strategy score after treatment, which was statistically higher than that of the control group(F<0.05). The amendment of IED EDS errors were positively correlated to the reductions in CDI total score and interpersonal problems item score (r=0.539, P=0.038; r=0.502, P=0.034). The amendment of DMS percent correct was negatively correlated to the reductions in negative mood item score(r=-0.585, P =0.011). The amendment of SOC four mean moves was positively correlated to the reductions in negative self-esteem item score(r=0.518, P=0.028). Conclusion The cognitive function can be improved after sertraline treatment in first-episode depressive adolescents correlated to the symptoms alleviation. Sertraline has no effect on working memory.%目的 探讨舍曲林对首发青少年抑郁症患者认知功能的影响及其相关因素.方法 对21例首发青少年抑郁症患者(抑郁症组)给予舍曲林(一日50 mg)治疗,共6周,并以21例健康者(健康对照组)为对照,评估治疗前后儿童抑郁量表(CDI)、威斯康辛卡片分类测验(WCST)、空间工作记忆(SWM)、剑桥袜(SOC)、目标内外注意转换(IED)和

    Major depressive disorder (MDD) is characterized by hypersensitivity to negative feedback that might involve frontocingulate dysfunction. MDD subjects exhibit enhanced electrophysiological responses to negative internal (errors) and external (feedback) cues. Whether this dysfunction extends to remitted depressed (RD) subjects with a history of MDD is currently unknown. To address this issue, we examined the feedback-related negativity (FRN) in RD and control subjects using a probabilistic punishment learning task. Despite equivalent behavioral performance, RD subjects showed larger FRNs to negative feedback relative to controls; group differences remained after accounting for residual anxiety and depressive symptoms. The present findings suggest that abnormal responses to negative feedback extend to samples at increased risk for depressive episodes in the absence of current symptoms. PMID:18580576

    Results from this randomized, placebo-controlled study of aripiprazole augmentation to antidepressant therapy (ADT) in Japanese patients with major depressive disorder (MDD) (the Aripiprazole Depression Multicenter Efficacy [ADMIRE] study) revealed that aripiprazole augmentation was superior to ADT alone and was well tolerated. In subgroup analyses, we investigated the influence of demographic- and disease-related factors on the observed responses. We also examined how individual symptom improvement was related to overall improvement in MDD. Data from the ADMIRE study were analyzed. Subgroup analyses were performed on the primary outcome measures: the mean change in the Montgomery-Åsberg Depression Rating Scale (MADRS) total score from the end of selective serotonin reuptake inhibitor (SSRI)/serotonin norepinephrine reuptake inhibitor (SNRI) treatment to the end of the randomized treatment. Changes in the MADRS total scores were consistently greater with aripiprazole than placebo in each of the subgroups. Efficacy was not related to sex, age, number of adequate ADT trials in the current episode, MDD diagnosis, number of depressive episodes, duration of the current episode, age at first depressive episode, time since the first depressive episode, type of SSRI/SNRI, or severity at the end of SSRI/SNRI treatment phase. Compared to placebo, aripiprazole resulted in significant and rapid improvement on seven of the 10 MADRS items, including sadness. These post-hoc analyses indicated that aripiprazole was effective for a variety of Japanese patients with MDD who had exhibited inadequate responses to ADT. Additionally, we suggest that aripiprazole significantly and rapidly improved the core depressive symptoms. © 2014 The Authors.

    Severe regional haze pollution events occurred in eastern and central China in January 2013, which had adverse effects on the environment and public health. Extremely high levels of particulate matter with aerodynamic diameter of 2.5 μm or less (PM2.5) with dominant components of sulfate and nitrate are responsible for the haze pollution. Although heterogeneous chemistry is thought to play an important role in the production of sulfate and nitrate during haze episodes, few studies have comprehensively evaluated the effect of heterogeneous chemistry on haze formation in China by using the 3-D models due to of a lack of treatments for heterogeneous reactions in most climate and chemical transport models. In this work, the WRF-CMAQ model with newly added heterogeneous reactions is applied to East Asia to evaluate the impacts of heterogeneous chemistry and the meteorological anomaly during January 2013 on regional haze formation. As the parameterization of heterogeneous reactions on different types of particles is not well established yet, we arbitrarily selected the uptake coefficients from reactions on dust particles and then conducted several sensitivity runs to find the value that can best match observations. The revised CMAQ with heterogeneous chemistry not only captures the magnitude and temporal variation of sulfate and nitrate, but also reproduces the enhancement of relative contribution of sulfate and nitrate to PM2.5 mass from clean days to polluted haze days. These results indicate the significant role of heterogeneous chemistry in regional haze formation and improve the understanding of the haze formation mechanisms during the January 2013 episode.

    Current intimate relationship characteristics, including gender and number of partner(s), may affect one's visibility as a bisexual individual and the minority stressors they experience, which may in turn influence their health. The current study tested four hypotheses: 1) minority stressors vary by current intimate relationship status; 2) higher minority stressors are associated with higher depressive symptoms and alcohol-related outcomes; 3) depressive symptoms and alcohol-related outcomes vary by current intimate relationship status; and 4) minority stressors will mediate differences in these outcomes. Participants included 470 self-identified bisexual women (65% Caucasian, mean age: 21) from a sample of sexual minority women recruited from different geographic regions in the United States through advertisements on social networking sites and Craigslist. Participants completed a 45 minute survey. Respondents with single partners were first grouped by partner gender (male partner: n=282; female partner: n=56). Second, women were grouped by partner gender/number (single female/male partner: n = 338; women with multiple female and male partners: n=132). Women with single male partners and women with multiple male and female partners exhibited elevated experienced bi-negativity and differences in outness (H1). Experienced and internalized bi-negativity were associated with health outcomes, but not outness (H2). Differences in outcomes emerged by partner number and partner number/gender (H3); these differences were mediated by experienced bi-negativity (H4). These results suggest that experiences of discrimination may underlie differences in health related to bisexual women's relationship structure and highlight the importance of evaluating women's relational context as well as sexual identification in understanding health risk behaviors.

    Several studies have reported that symptoms of anxiety and depression are significantly associated with diseases characterized by painful crises. However, there is little information about the psychological aspects of recurrent painful episodes of renal stone disease. Our objective was to evaluate the association of symptoms of anxiety, depression and recurrent painful renal colic in a case-control study involving 64 subjects (32 cases/32 controls) matched for age and sex. Cases were outpatients with a confirmed diagnosis of nephrolithiasis as per their case history, physical examination, image examination and other laboratory exams. Patients had a history of at least two episodes within a 3-year period, and were currently in an intercrisis interval. The control group consisted of subjects seen at the Ophthalmology Outpatient Clinic of this University Hospital with only eye refraction symptoms, and no other associated disease. Symptoms of anxiety were evaluated by the State-Trait Anxiety Inventory and symptoms of depression by the Beck Depression Inventory. Statistically significant differences were observed between patients with nephrolithiasis and controls for anxiety state (P = 0.001), anxiety trait (P = 0.005) and symptoms of depression (odds ratio = 3.74; 95%CI = 1.31-10.62). The Beck Depression Inventory showed 34.5% of respondents with moderate and 6% with severe levels of depression. There was a significant linear correlation between symptoms of anxiety (P = 0.002) and depression (P renal colic and symptoms of both anxiety and depression.

However, it is an undeniable source of stress, with consequences for physical and mental health. The prevalence of depression and somatic complaints were assessed in 1,013 public workers using the Beck Depression Inventory and a questionnaire investigating for the presence of somatic problems designed by the research team. The results were related to demographic characteristics, history of previous depressive episodes, work schedule (day work, night and day rotating shift work, day rotating shift work, and duration of current work schedule. There were more cases of moderate depression in the day rotating shift workers (84% than in those working at night (83%. More women had mild or moderate depression than men (22% and 4% versus 10% and 3%, respectively. Severe depression was found only in men. Nearly 10% of depressed individuals reported previous depressive episodes. A link between depression and somatic complaints was also found. In particular, 59% of depressed subjects reported gastrointestinal complaints and 41% did not (P<0.001. In conclusion, the occurrence of depressive symptoms could be facilitated by occupation. A history of depressive symptoms should not be neglected, given the risk of recurrence. Somatic complaints could represent a “wake-up call” regarding depression. Global assessment and effective support are fundamental for promotion of a better quality of life in the at-risk category of workers

Methods Self rotation tasks were conducted on twenty-three patients with first-episode depressive disorders and 22 normal healthy people. Their neuropsy-chological performance and latency and amplitude of P500 were measured during self rotation tasks. Results Compared with normal control group, error rates of the left and right hand were significantly higher [left hand; (28 ± 5)% vs. (24 ± 4)%, right hand; (26 ± 4)% vs. (24 ± 3)%], P < 0.05); reaction time for left and right hand was significantly longer [left hand; (1193.79 ± 53.32)ms vs. (742.62 ± 15.2l)ms, right hand; (1105.57 ± 51.61) ms vs. (732.10 ± 16.53)ms, all P < 0.05] in the depression group. The elevated error rate and extended reaction time were higher in the left hand rotation than in the right hand rotation. Compared with control group, latencies in the left and right hand were significantly longer [left hand; (551.37 ± 45.27)ms vs. (508.22 ± 28.22) ms, right hand: (542.74 ± 46.73) ms vs. (507.52 ± 31.48)ms, all P < 0.05], and volatility in the left and right hand were significantly lower [left hand: (5.22 ± 2.41 )μV vs. (8.28 ± 3.11)μV, right hand: (6.79 ± 3.24)μV vs. (8.29 ± 3.41 )μV, P < 0.05] in the depression group. The prolonged latencies and reduced volatility were more pronounced in the left hand rotation than in the right hand rotation in the depression group. Conclusion This study shows that depressed patients have deficits in self rotation in which the speed and depth of information processing are damaged. The deficits in self rotation were more severe in the left hand than in the right hand, suggesting different mechanisms for the information processing between the left and right hands.%目的 探讨抑郁症的自我旋转能力及其脑电生理机制,进一步了解抑郁症空

    Full Text Available This review examines the effects of family-based psychoeducation programs to the prevention depression for children of depressed parents and investigates participant, intervention, provider, and research designs. Family-based psychoeducation programs described by articles in several national and international databases were reviewed. Five studies were identified using this approach and are included in this review. The adolescents who participated in Family-Based Psychoeducation programs reported a significant decrease in symptoms of depression, internalizing and externalizing symptoms and increase in secondary control coping. Moreover, it was noted that there was an increase in positive parental skills and a moderate effect for episodes of depression of the parents who participated in the programs. Studies evaluating effects of family-based psychoeducation programs have indicated positive results to the prevention depression for children of depressed parents.

    Copper may be involved in the pathophysiology of depression. Clinical data on this issue are very limited and not conclusive. The purpose of the study was to determine the copper concentration in the serum of patients with major depressive disorder and to discuss its potential clinical usefulness as a biomarker of the disease. A case-control clinical study included 69 patients with current depressive episode, 45 patients in remission and 50 healthy volunteers. Cu concentration was measured by electrothermal atomic absorption spectrometry (ETAAS). The mean serum copper level in depressed patients was slightly lower (by 11 %; not statistically significant) than in the control group. Furthermore, there was no significant difference in Cu(2+) concentration between depressive episode and remission, nor between remission and control group. In the remission group were observed significant correlations between copper levels and the average number of relapses over the past years or time of remission. There was no correlation between serum copper and severity of depression, as measured by HDRS and MADRS. The obtained results showed no significant differences between the copper concentration in the blood serum of patients (both with current depressive episode and in remission) and healthy volunteers, as well as the lack of correlations between the copper level in the active stage of the disease and clinical features of the population. Our study is the first conducted on such a large population of patients, so the results may be particularly important and reliable source of knowledge about the potential role of copper in depression.

    Cardiac conduction disorders are common diseases which cause slow heart rate and syncope. The best way to treat these diseases by now is to implant electronic pacemakers, which, yet, have many disadvantages, such as the limited battery life and infection. Biopacemaker has been expected to replace the electronic devices. Automatic ventricular myocytes (VMs) could show pacemaker activity, which was induced by depressing inward-rectifier K(+) current (I K1). In this study, a 2D model of human biopacemaker was created from the ventricular endocardial myocytes. We examined the stability of the created biopacemaker and investigated its driving capability by finding the suitable size and spatial distribution of the pacemaker for robust pacing and driving the surrounding quiescent cardiomyocytes. Our results suggest that the rhythm of the pacemaker is similar to that of the single cell at final stable state. The driving force of the biopacemaker is closely related to the pattern of spatial distribution of the pacemaker.

    Full Text Available In addition to their classical roles in neuronal growth, survival and differentiation, neurotrophins are also rapid regulators of excitability, synaptic transmission and activity-dependent synaptic plasticity. We have recently shown that mature BDNF (Brain Derived Neurotrophic Factor, but not proBDNF, modulates the excitability of interneurons in dentate gyrus within minutes. Here, we used brain slice patch-clamp recordings to study the mechanisms through which BDNF modulates the firing of interneurons in rat dentate gyrus by binding to TrkB receptors. Bath application of BDNF (15 ng/ml under current-clamp decreased the firing frequency (by 80% and input resistance, blocking the delayed firing observed at near-threshold voltage ranges, with no changes in resting membrane potential or action potential waveform. Using TEA (tetraethylammonium, or XE991(a Kv7/KCNQ channel antagonist, the effect of BDNF was abolished, whereas application of retigabine (a Kv7/KCNQ channel opener mimicked the effect of BDNF, suggesting that the M-current could be implicated in the modulation of the firing. In voltage-clamp experiments, BDNF increased the M-like current amplitude with no change in holding current. This effect was again blocked by XE991 and mimicked by retigabine, the latter accompanied with a change in holding current. In agreement with the electrophysiology, parvalbumin-positive interneurons co-expressed TrkB receptors and Kv7.2/KCNQ2 channels. In conclusion, BDNF depresses the excitability of interneurons by activating an M-like current and possibly blocking Kv1 channels, thereby controlling interneuron resting membrane potential and excitability.

    2003-11-01

    This cross-sectional, retrospective study used epidemiological and anthropological methods toward two aims: 1) to examine associations between partner violence and major depression in a community probability sample of women and 2) to provide new data on partner violence in Chinese Americans. In this study, 181 Chinese American women were interviewed, with 178 completing structured sections on CIDI 2.1 major depression and on partner violence history. Results indicate that a history of partner violence is associated with significantly higher rates of lifetime, 12-month, and current major depression in this community population. This effect is specific and independent of other factors. Partner violence also has a dose-response relationship with the severity of major depression episodes, increasing risk for severe and moderate episodes. The strength and specificity of this association, its dose-response effect, and its commonality across different populations suggest a possible causal role for partner violence needing further investigation in research on major depression in women.

    Happiness is a core dimension of a person's life, related to both functioning and success. As patients with schizophrenia experience marked functional deficits, it would be informative to investigate their level of happiness. There are limited data currently available, perhaps due to the longstanding belief that anhedonia is an inherent feature of this illness. The present study set out to specifically assess happiness in schizophrenia in relation to both clinical and functional measures of outcome. Thirty-one first-episode remitted patients and 29 age- and sex-matched controls participated in the study. Patients' clinical status was assessed and a series of self-report questionnaires were used to measure levels of happiness, life satisfaction, success and functioning in both patients and controls. Patients experienced marked functional impairment versus healthy controls (phappiness (p=0.113) and satisfaction with life (p=0.350). In the patient group, we found that higher happiness ratings were significantly associated with less depression, less negative symptoms, less social withdrawal, greater life satisfaction, and higher social and occupational functioning. Both cognitive functioning and insight had no significant direct effects on ratings of happiness in the patient group. Despite marked functional impairment, individuals with first-episode schizophrenia are as happy as controls. Mechanisms that might allow for this are discussed, as are the implications for rehabilitation efforts that assume an individual holds to the same drives and goals as before the illness onset and/or is unhappy with their present functional status.

    Full Text Available Transcranial direct current stimulation (tDCS is a novel non-invasive neuromodulatory method that influences neuronal firing rates and activity on dopaminergic and serotoninergic circuits. TDCS has been shown to relieve Major Depressive Disorder (MDD in the general population, suggesting its potential for other vulnerable -populations with high MDD prevalence. Aims: This study evaluated l feasibility, safety, acceptability and clinical outcomes of a two-week tDCS antidepressant treatment in HIV-MDD co-diagnosed patients, and the feasibility of collecting serum and saliva for analysis of immunity-biomarkers.. Methods: Ten enrolled patients underwent baseline evaluation and started the tDCS treatment (Mon-Fri for two weeks delivered with Phoressor II 850 PM for 20 min at 2 mA at each visit, using 2 electrodes (36cm2 placed over F3 position of EEG 10-20 system and the contralateral supraorbital region. Outcome-measures were collected at baseline, after the last tDCS and two weeks later. A quantitative microarray (Ray Bio Tech Inc for TH1/TH2 cytokines was used for saliva and blood analysis. Results: Analyzable outcome-data were obtained from 8 subjects. Depression scores significantly decreased (p<.0005 after the treatment. No serious adverse events occurred. Several transient minor AEs and occasional changes of blood pressure and heart rate were noted. Mini-mental status scores remained unchanged or increased after the treatment. All subjects were highly satisfied with the protocol and treatment results and described the desire to find new treatments for HIV-MDD as motivating participation. Conclusions: F indings support feasibility and clinical potential of tDCS for HIV-MDD patients, and justify larger-sample, sham-controlled trials.

    Background Dual processing models of psychopathology emphasize the relevance of differentiating between deliberative self-evaluative processes (explicit self-esteem; ESE) and automatically-elicited affective self-associations (implicit self-esteem; ISE). It has been proposed that both low ESE and ISE would be involved in major depressive disorder (MDD) and anxiety disorders (AD). Further, it has been hypothesized that MDD and AD may result in a low ISE “scar” that may contribute to recurrence after remission. However, the available evidence provides no straightforward support for the relevance of low ISE in MDD/AD, and studies testing the relevance of discrepant SE even showed that especially high ISE combined with low ESE is predictive of the development of internalizing symptoms. However, these earlier findings have been limited by small sample sizes, poorly defined groups in terms of comorbidity and phase of the disorders, and by using inadequate indices of discrepant SE. Therefore, this study tested further the proposed role of ISE and discrepant SE in a large-scale study allowing for stricter differentiation between groups and phase of disorder. Method In the context of the Netherlands Study of Depression and Anxiety (NESDA), we selected participants with current MDD (n = 60), AD (n = 111), and comorbid MDD/AD (n = 71), remitted MDD (n = 41), AD (n = 29), and comorbid MDD/AD (n = 14), recovered MDD (n = 136) and AD (n = 98), and never MDD or AD controls (n = 382). The Implicit Association Test was used to index ISE and the Rosenberg Self-Esteem Scale indexed ESE. Results Controls reported higher ESE than all other groups, and current comorbid MDD/AD had lower ESE than all other clinical groups. ISE was only lower than controls in current comorbid AD/MDD. Discrepant self-esteem (difference between ISE and ESE) was not associated with disorder status once controlling for ESE. Limitations Cross-sectional design limits causal inferences. Conclusion Findings

    Individuals with concurrent tobacco dependence and other addictions often report symptoms of low mood and depression and as such may have more difficulty quitting smoking. We hypothesized that current symptoms of depression would be a significant predictor of quit success among a group of smokers receiving individualized treatment for tobacco dependence within addiction treatment settings. Individuals in treatment for other addictions were enrolled in a smoking cessation program involving brief behavioral counseling and individualized dosing of nicotine replacement therapy. The baseline assessment included the Patient Health Questionnaire (PHQ9) for depression. Smoking cessation outcomes were measured at 3 and 6 months post-enrollment. Bivariate associations between cessation outcomes and PHQ9 score were analyzed. Of the 1,196 subjects enrolled to date, 1,171 (98%) completed the PHQ9. Moderate to severe depression (score >9) was reported by 28% of the sample, and another 29% reported mild depression (score between 5 and 9). Contrary to the extant literature and other findings by our own group, there was no association between current depression and cessation outcome at either 3 months (n = 1,171) (17.0% in those with PHQ9 > 9 vs. 19.8% in those with PHQ9 addictions treatment setting. These data indicate that patients in an addictions treatment setting can successfully quit smoking regardless of current depressive symptoms. © The Author 2015.

  5. Depression and creativity - the case of the German poet, scientist and statesman J. W. v. Goethe.

    Goethe was one of the most creative poets, scientists and statesmen ever existing. Since the age of fourteen, he suffered from severe mood swings. His descriptions of feelings, emotions, and mental states related to temperamental and poetic melancholy, depressive episodes, dysthymic phases, and creativity are unique in respect to their phenomenological precision and richness. Furthermore, his (self-) therapeutic strategies and his self transformation in literature remain interesting until today for psychopathology, psychotherapy and creativity research. Goethe's self-assessments in his works and letters as well as the description of him by others are analysed by phenomenological and hermeneutic methods from the perspective of current psychiatric classification and psychotherapeutic knowledge. From a modern scientific perspective Goethe's mood swings are not to be regarded as expressions of a "poet's melancholy" in fashion at his time but as symptoms of depressive episodes. Several distinctive depressive episodes can be diagnosed which were characterized by long lasting depressive mood, lack of drive, interests and self-esteem combined with social retreat and physical illness. Moreover, Goethe described a mood disorder which fits into the modern concept of "driven dysthymia" or Bipolar II disorder. Goethe's depressive moods were associated with eminent poetic creativity whereas in times of scientific and political productivity Goethe seemed to be protected against depressive episodes. Phenomenological and hermeneutic analysis cannot offer causal explanations but only reasons for understanding and communicative action. In Goethe's life poetic incubation, illumination and elaboration seemed to be associated with psychic labilisation and dysthymia, sometimes with depressive episodes in a clinical sense. Thus, creative work was on the one hand triggered by depressive and dysthymic moods and served on the other hand to cope with depressive moods as well as with suicidal

    Objective To evaluate impairment of cognitive function in first-episode schizophrenia, bipolar disor⁃der and major depressive disorder. Methods Sixty one first-episode schizophrenia patients, fifty seven bipolar disorder patients, forty eight major depressive disorder patients and fifty nine healthy controls were recruited. Cognitive function of all subjects was assessed using Repeatable Battery for the Assessment of Neuropsychological Status (RBANS). The psychiatric symptoms of schizophrenia patients and the depressive, anxiety symptoms and manic symptoms of bipolar dis⁃order patients and major depressive patients were assessed using positive and negative syndrome scale (PANSS), Hamil⁃ton depression scale (HAMD), Hamilton anxiety scale (HAMA) and Bech-Rafaelsen mania scale (BRMS), respectively. Results The total score of RBANS (F=5.18,P<0.01). and the factor scores of immediate memory (F=9.53,P<0.01), de⁃layed memory (F=3.87,P=0.01) and language function (F=9.86,P<0.01) were significantly different in four groups. Com⁃pared to healthy controls, the total score of RBANS were significantly lower in first-episode schizophrenia group and bi⁃ polar disorder group (P<0.01), and the factor scores of immediate memory, delayed memory and language function were significantly lower in first-episode schizophrenia group, bipolar disorder group and major depressive group (P<0.05). Ma⁃jor depressive group performed worse than first-episode schizophrenia group in language function factor (P<0.01). The factor score of attention in first-episode schizophrenia group was significantly lower than major depressive and control group (P<0.01). Conclusions First-episode schizophrenia, bipolar disorder and major depressive disorder are associated with significant cognitive impairments. Cognitive function impairments in the patients with first-episode schizophrenia are worse than patients with major depressive disorder, but better than patients with bipolar disorder.%目的

    Schizophrenia is one of the main health problems in current days, requiring considerable investment from the health system. Intervening in the first episode offers a unique opportunity in the treatment of schizophrenia and influences the course of the illness. This article consists of a critical literature review aimed at examining knowledge on first episode schizophrenia and discussing the contribution of nursing care. A research was carried out in bibliographical databases. The data collected made possible the organization of information on the general concept of schizophrenia, its first episode, types of intervention and nursing performance. We found out that in Brazil there are few studies related to first episode schizophrenia in Nursing, few available specialized services, and few social resources. This situation reveals the need for more studies on first episode schizophrenia.

    Full Text Available Several studies have reported that symptoms of anxiety and depression are significantly associated with diseases characterized by painful crises. However, there is little information about the psychological aspects of recurrent painful episodes of renal stone disease. Our objective was to evaluate the association of symptoms of anxiety, depression and recurrent painful renal colic in a case-control study involving 64 subjects (32 cases/32 controls matched for age and sex. Cases were outpatients with a confirmed diagnosis of nephrolithiasis as per their case history, physical examination, image examination and other laboratory exams. Patients had a history of at least two episodes within a 3-year period, and were currently in an intercrisis interval. The control group consisted of subjects seen at the Ophthalmology Outpatient Clinic of this University Hospital with only eye refraction symptoms, and no other associated disease. Symptoms of anxiety were evaluated by the State-Trait Anxiety Inventory and symptoms of depression by the Beck Depression Inventory. Statistically significant differences were observed between patients with nephrolithiasis and controls for anxiety state (P = 0.001, anxiety trait (P = 0.005 and symptoms of depression (odds ratio = 3.74; 95%CI = 1.31-10.62. The Beck Depression Inventory showed 34.5% of respondents with moderate and 6% with severe levels of depression. There was a significant linear correlation between symptoms of anxiety (P = 0.002 and depression (P < 0.001 and the number of recurrent colic episodes (anxiety-state: P = 0.016 and anxiety-trait: P < 0.001. These data suggest an association between recurrent renal colic and symptoms of both anxiety and depression.

    Theory of mind (ToM) to infer other people's current mental states and episodic memory of personal happenings have been assumed to be closely related. We report two participants with severely impaired episodic memory who perform indistinguishably from healthy controls on objective ToM tests. These results suggest that ToM can function independently of episodic memory.

    Cannabinoid receptor 1 (CB1) gene (CNR1) knockout mice are prone to develop anhedonic and helpless behavior after chronic mild stress. In humans, the CB1 antagonist rimonabant increases the risk of depressed mood disorders and anxiety. These studies suggest the hypothesis that genetic variation in CB1 receptor function influences the risk of depression in humans in response to stressful life events. In a population sample (n=1269), we obtained questionnaire measures of personality (Big Five Inventory), depression and anxiety (Brief Symptom Inventory), and life events. The CNR1 gene was covered by 10 SNPs located throughout the gene to determine haplotypic association. Variations in the CNR1 gene were significantly associated with a high neuroticism and low agreeableness phenotype (explained variance 1.5 and 2.5%, respectively). Epistasis analysis of the SNPs showed that the previously reported functional 5' end of the CNR1 gene significantly interacts with the 3' end in these phenotypes. Furthermore, current depression scores significantly associated with CNR1 haplotypes but this effect diminished after covariation for recent life events, suggesting a gene x environment interaction. Indeed, rs7766029 showed highly significant interaction between recent negative life events and depression scores. The results represent the first evidence in humans that the CNR1 gene is a risk factor for depression--and probably also for co-morbid psychiatric conditions such as substance use disorders--through a high neuroticism and low agreeableness phenotype. This study also suggests that the CNR1 gene influences vulnerability to recent psychosocial adversity to produce current symptoms of depression.

    Attentional deficits are considered key cognitive symptoms in major depressive disorder (MDD) arising from abnormal activation patterns within dorsolateral prefrontal cortex (dlPFC) alertness networks. Altering these activity patterns with transcranial direct current stimulation (tDCS) might thus ameliorate alertness-dependent cognitive deficits in MDD patients. In a double-blind, randomized, sham-controlled study, we investigated the effect of a single session of anodal tDCS (2 mA) applied to the left dlPFC on different parameters of visual attention based on Bundesen's theory of visual attention (Psychol Rev 97(4):523-547, 1990) in a group of 20 patients with MDD and a control group of 20 healthy participants. The parametric attention assessment took place before, immediately after and 24 h after tDCS intervention. It revealed a selective impairment in visual processing speed as a primary functional deficit in MDD at baseline assessment. Furthermore, a significant stimulation condition × time point interaction showed that verum tDCS over the left dlPFC resulted in a processing speed enhancement 24 h post-stimulation in MDD patients. In healthy control participants, we did not find similar tDCS-induced effects. Our results suggest that even a single session of tDCS over the dlPFC can induce enduring neurocognitive benefits that indicate an amelioration of cortical under-arousal in MDD patients in a time frame beyond that of immediate, excitability increases that are directly induced by the current.

    During Younger Dryas episode (12. 9 ~11. 6 cal. Ka), the sea level oscillated at about - 66 m depth contour in the continental shelf seas in eastern China and the seawater got into the south of the present North Yellow Sea,so Yellow Sea became a long narrow channel gulf. To simulate the tidal current of this special gulf, Environmental Fluid Dynamics Computer Code is used in this paper. The calculation combines curvilinear orthogonal coordinates in the horizontal direction with Sigma mapping coordinates in the vertical direction, and it uses a method which transforms a problem from three-dimension into two-dimension. The results show that the tidal current was still very strong in Yellow Sea during Younger Dryas episode, entering the special gulf along the right side entrance. From both shallow sides to deep centre, rotating flow changes reciprocating flow. Under the effect of reciprocating flow, the floor is eroded and the mud and sand are carried away. Progressive wave turns into rotating wave and two ateliotic amphidromic points appear on the western side of the gulf after tidal wave coming into Yellow Sea. At the same time, tidal residual current flows to southeast and east with relatively great velocity at the west and interior gulf and it becomes weakly near the entrance. The current may carry the bottom sediments and discharge them to the present mud sediment zone in north East China Sea. But at eastern Yellow Sea the tidal residual current flows to north and forms an anticlockwise circulation at centre of the eastern gulf which is corresponding to the eddy mud zone in Southeast Yellow Sea (Heishan mud zone). The anticlockwise circulation captures suspended sediment and may gestate the present mud sediment zone. The extension direction of tidal sand ridges and the size composition of the tidal current sand in eastern South Yellow Sea have a close relationship with the tidal current field of the ancient Yellow Sea, so the less fluctuating sea level changing

    This study screened the prevalence and correlates of dissociative disorders among depressive women in the general population. The Dissociative Disorders Interview Schedule and the posttraumatic stress disorder (PTSD) and borderline personality disorder sections of the Structured Clinical Interview for DSM-IV were administered to 628 women in 500 homes. The prevalence of current major depressive episode was 10.0%. Of the women, 26 (40.6%) had the lifetime diagnosis of a DSM-IV, dissociative disorder, yielding a prevalence of 4.1% for dissociative depression. This group was younger (mean age = 30.7 years) than the nondissociative depression women (mean age = 39.6 years). There was no difference between the 2 groups on comorbid somatization disorder, PTSD, or borderline personality disorder. Besides suicide attempts, the dissociative group was characterized by secondary features of dissociative identity disorder; Schneiderian symptoms; borderline personality disorder criteria; and extrasensory perceptions, including possession experiences. They reported suicidality, thoughts of guilt and worthlessness, diminished concentration and indecisiveness, and appetite and weight changes more frequently than the nondissociative group. Early cessation of school education and childhood sexual abuse were frequently reported by the dissociative depression group. With its distinct features, the concept of dissociative depression may facilitate understanding of treatment resistance in, development of better psychotherapy strategies for, and new thinking on the neurobiology and pharmacotherapy of depressive disorders.

    Personality traits in euthymic elderly subjects with and without past histories of major depressive episodes were assessed using the Structured Clinical Interview for DSM-III-R and the Social Adjustment Scale-SR. Recovered depressed subjects were characterized by significantly more personality traits from DSM-III-R Clusters B and C than controls, and they exhibited differences in social adjustment, as well. Subjects who have recovered from depressive episodes may show significant differences in personality and social adjustment that might represent residua of past depression, a trait characteristic, or a risk factor for recurrence.

    Full Text Available Abstract Background Prevalence of depressive disorders among adolescents has varied across studies. The present study aims to assess current and lifetime prevalence and characteristics of adolescent Major Depressive Disorder (MDD, Dysthymia and Depression NOS among adolescents in Central Norway in addition to socio-demographics and use of mental health care. Method In the Youth and Mental Health Study a representative sample of 2432 junior high school students (mean age 14.9 years, SD = 0.6 from two counties in Central Norway were screened with the Mood and Feelings Questionnaire (MFQ. A subset of 345 of these adolescents (72.5% girls, 220 high scorers (MFQ = > 26, 74 middle scorers (MFQ 7-25, and 50 low scorers (MFQ Results Almost one in four subjects (23% had life-time depression. Prevalences of current Major Depressive Disorder (MDD, Dysthymia and "Double depression" were 2.6%, 1.0% and 0.6%, respectively, and for Depression NOS 6.3%. All depressive disorders were characterized by long duration of episodes with large variations, and for any depressive disorder onset before 12 years of age. In multivariate analyses MDD and Dysthymia were most strongly associated with gender and not living with both biological parents. There was no gender difference for Depression NOS. Although a considerable number of depressed subjects had received mental health care, the reason for contact with services was seldom due to affective symptoms. Less than 20% had been in contact with specialist mental health services. Conclusion High rates of Depression NOS, early onset of depressive episodes, long duration, and low use of specialized services point to the need for improved diagnostic assessment and treatment for young individuals.

  3. Suicidal Ideation Induced by Episodic Cannabis Use

    2009-01-01

    Full Text Available The report describes a patient who presented suicidal ideation only in two different occasions, immediately after acute cannabis intoxication. He used cannabis only in these two circumstances. Although a definite association between cannabis use and suicidal ideation or behavior has been already reported in the literature, the described case presents two original clinical aspects that deserve consideration. First, episodic assumption of cannabis induced suicidal ideation abruptly. Second, suicidal ideation appeared independent of mood depression, stressors, or life events, suggesting that suicidality may be not a direct consequence of depression and appears to be a relatively independent psychopathological dimension. There seems to be no linear relation between the severity of depression and the risk of suicide.

No primary or secondary efficacy outcome measures were found comparing oxcarbazepine with lithium monotherapy.As an adjunctive treatment to lithium, oxcarbazepine reduced depression rating scale scores more than carbamazepine in a group of manic participants on the Montgomery-Åsberg Depression Rating Scale (MADRS) (SMD=- 1.12, 95% CI -1.71 to -0.53, 1 study, n=52, P=0.0002) and on the Hamilton Depression Rating Scale (HDRS) (SMD=- 0.77, 95% CI -1.35 to -0.20, 1 study, n=52, P=0.008).There was a higher incidence of adverse effects, particularly neuropsychiatric, in participants randomised to oxcarbazepine compared to those on placebo (1 study, n=115, 17% to 39% of participants on oxcarbazepine had at least one such event compared to 7% to 10% on placebo).There was no difference in adverse events rates between oxcarbazepine and other mood stabilisers or haloperidol. Currently, there are insufficient trials of adequate methodological quality on oxcarbazepine in the acute treatment of bipolar disorder to inform us on its efficacy and acceptability. Studies predominantly examine the treatment of mania: there are data from subgroup analysis on mixed affective, hypomania and rapid-cycling states.From the few studies included in this review, oxcarbazepine did not differ in efficacy compared to placebo in children and adolescents. It did not differ from other active agents in adults. It may have a poorer tolerability profile compared to placebo. No data were found on outcomes relevant to patients and clinicians, such as length of hospital admission.  There is a need for adequately powered randomised controlled trials of good methodological quality to inform us of the therapeutic potential of oxcarbazepine across the spectrum of acute episodes in bipolar disorder.

    Can atypical patterns of parasympathetic nervous system activity serve as endophenotypes for depression? Using respiratory sinus arrhythmia (RSA) as an index of parasympathetic nervous system function, we examined this question in two studies: one involving mothers with and without depression histories and their offspring (at high and low risk for depression, respectively), and a further study of adolescent sibling pairs concordant and discordant for major depression. In both studies, subjects were exposed to sad mood induction; subjects’ RSA was monitored during rest periods and in response to the mood induction. We used Gottesman and Gould’s (2003) criteria for an endophenotype and a priori defined “atypical” and “normative” RSA patterns (combinations of resting RSA and RSA reactivity). We found that atypical RSA patterns (a) predicted current depressive episodes and remission status among women with histories of juvenile onset depression and healthy controls, (b) predicted longitudinal trajectories of depressive symptoms among high- and low-risk young offspring, (c) were concordant across mothers and their juvenile offspring, (d) were more prevalent among never-depressed youth at high risk for depression than their low-risk peers, and (e) were more concordant across adolescent sibling pairs in which both versus only one had a history of major depression. Thus, the results support atypical RSA patterns as an endophenotype for depression. Possible mechanisms by which RSA patterns increase depression risk and their genetic contributors are discussed.

    Objective The primary goal of this paper is to examine and clarify characteristics of binge eating in individuals with binge eating disorder (BED), particularly the duration of binge eating episodes, as well as potential differences between individuals with shorter compared to longer binge eating episodes. Method Two studies exploring binge eating characteristics in BED were conducted. Study 1 examined differences in clinical variables among individuals (N = 139) with BED who reported a short (binge duration. Study 2 utilized an ecological momentary assessment (EMA) design to examine the duration and temporal pattern of binge eating episodes in the natural environment in a separate sample of nine women with BED. Results Participants in Study 1 who were classified as having long duration binge eating episodes displayed greater symptoms of depression and lower self-esteem, but did not differ on other measures of eating disorder symptoms, compared to those with short duration binge eating episodes. In Study 2, the average binge episode duration was approximately 42 minutes, and binge eating episodes were most common during the early afternoon and evening hours, as well as more common on weekdays versus weekends. Discussion Past research on binge episode characteristics, particularly duration, has been limited to studies of binge eating episodes in BN. This study contributes to the existing literature on characteristics of binge eating in BED. PMID:23881639

    @@ The diagnosis of bipolar rather than unipolar depression is currently a clinicaI diagnosis which cannot be validated by specific biological measures,such as laboratory tests.Certainly the characteristics of bipolar depression frequently differ from unipolar major depression in that patients with bipolar depression generally have an earlier age of onset and more frequent episodes than individuals with unipolar major depression[1]Some,but not all,studies support an increase in suicidal behaviors among bipolar as compared with unipolar major depression[2],and"atypical features"such as hypersomnia and hyperphagia also may be found more frequently among individuals with bipolar depression.Furthermore family histories of subjects with bipolar disorders more frequently reveal relatives with bipolar disorder.In contrast,relatives of patients with unipolar depression's family history generally reflects major depression but not bipolar disorder[3].

    esclarecer seu real papel no manejo dos transtornos depressivos.OBJECTIVE: In recent years, a number of new somatic (non-pharmacological treatments have been developed for the treatment of major depression and other neuropsychiatric disorders. Among these, one of the most promising is transcranial direct current stimulation. Method: For the present literature review we searched the PubMed between January 1985 and February 2009. To be included, articles should have been published in English and should address general principles of transcranial direct current stimulation and its use in major depression. DISCUSSION: Current protocols for the treatment of major depression with transcranial direct current stimulation usually involve the application of two sponge-electrodes in the scalp. In general, the positive electrode is applied in the region above the left dorsolateral prefrontal cortex (i.e., F3 region of the 10/20 International System for EEG and the negative electrode is applied in the region above the right supra-orbital area. A direct electrical current of 1-2 mA is then applied between the electrodes for about 20 minutes, with sessions being daily performed for one to two weeks. Initial studies (including a randomized, double-blind, placebo-controlled clinical trial showed that transcranial direct current stimulation is effective for the treatment of non-complicated major depression and that this technique, when used in depressed patients, is associated with improvement in cognitive performance (including working memory. Finally, transcranial direct current stimulation is safe and well tolerated. CONCLUSION: Recent studies show that transcranial direct current stimulation is an important neuromodulatory method that may be useful for the treatment of depressed patients. However, further studies are needed to better clarify its precise role in the management of depressive disorders.

    2013-01-01

    Full Text Available Abstract Background Major depression is a widely used diagnostic category but there is increasing dissatisfaction with its performance. The diathesis-stress model is an alternative approach that does not require the (sometimes arbitrary imposition of categories onto the spectrum of depressive morbidity. However, application of this model has not been well explored and its consistency with available epidemiologic data is uncertain. Methods Simulation provides an opportunity to explore these issues. In this study, a simulation model based on an intuitive representation of diathesis-stress interaction was developed. Both diathesis and stress were represented using continuous distributions, without categorization. A diagnostic threshold was then applied to the simulation output to create nominal categories and to explore their consistency with available information. Results An apparently complex epidemiologic pattern emerged from the diathesis-stress interaction when thresholds were applied: incidence was time dependent, recurrence depended on the number of past episodes, baseline symptoms were associated with an increased risk of subsequent episodes and the remission rate declined with increasing episode duration. Conclusions A diathesis-stress conceptualization coupled with application of a threshold-based diagnostic definition may explain several of the apparent complexities of major depression epidemiology. Some of these complexities may be artifacts of the nominal diagnostic approach. These observations should encourage an empirical exploration of whether diathesis-stress interactions provide a more parsimonious framework for understanding depression than current approaches.

    Anhedonia--which is defined as diminished pleasure from, or interest in, previously rewarding activities-is one of two cardinal symptoms of a major depressive episode. However, evidence suggests that standard treatments for depression do little to alleviate the symptoms of anhedonia and may cause reward blunting. Indeed, no therapeutics are currently approved for the treatment of anhedonia. Notably, over half of patients diagnosed with bipolar disorder experience significant levels of anhedonia during a depressive episode. Recent research into novel and rapid-acting therapeutics for depression, particularly the noncompetitive N-Methyl-D-aspartate receptor antagonist ketamine, has highlighted the role of the glutamatergic system in the treatment of depression; however, it is unknown whether ketamine specifically improves anhedonic symptoms. The present study used a randomized, placebo-controlled, double-blind crossover design to examine whether a single ketamine infusion could reduce anhedonia levels in 36 patients with treatment-resistant bipolar depression. The study also used positron emission tomography imaging in a subset of patients to explore the neurobiological mechanisms underpinning ketamine's anti-anhedonic effects. We found that ketamine rapidly reduced the levels of anhedonia. Furthermore, this reduction occurred independently from reductions in general depressive symptoms. Anti-anhedonic effects were specifically related to increased glucose metabolism in the dorsal anterior cingulate cortex and putamen. Our study emphasizes the importance of the glutamatergic system in treatment-refractory bipolar depression, particularly in the treatment of symptoms such as anhedonia.

    Full Text Available We describe a novel computational theory of how individuals segment perceptual information into representations of events. The theory is inspired by recent findings in the cognitive science and cognitive neuroscience of event segmentation. In line with recent theories, it holds that online event segmentation is automatic, and that event segmentation yields mental simulations of events. But it posits two novel principles as well: first, discrete episodic markers track perceptual and conceptual changes, and can be retrieved to construct event models. Second, the process of retrieving and reconstructing those episodic markers is constrained and prioritized. We describe a computational implementation of the theory, as well as a robotic extension of the theory that demonstrates the processes of online event segmentation and event model construction. The theory is the first unified computational account of event segmentation and temporal inference. We conclude by demonstrating now neuroimaging data can constrain and inspire the construction of process-level theories of human reasoning.

  19. Is blunted cardiovascular reactivity in depression mood-state dependent? A comparison of major depressive disorder remitted depression and healthy controls.

    Prior work has repeatedly demonstrated that people who have current major depression exhibit blunted cardiovascular reactivity to acute stressors (e.g., Salomon et al., 2009). A key question regards the psychobiological basis for these deficits, including whether such deficits are depressed mood-state dependent or whether these effects are trait-like and are observed outside of depression episodes in vulnerable individuals. To examine this issue, we assessed cardiovascular reactivity to a speech stressor task and a forehead cold pressor in 50 individuals with current major depressive disorder (MDD), 25 with remitted major depression (RMD), and 45 healthy controls. Heart rate (HR), blood pressure and impedance cardiography were assessed and analyses controlled for BMI and sex. Significant group effects were found for SBP, HR, and PEP for the speech preparation period and HR, CO, and PEP during the speech. For each of these parameters, only the MDD group exhibited attenuated reactivity as well as impaired SBP recovery. Reactivity and recovery in the RMD group more closely resembled the healthy controls. Speeches given by the MDD group were rated as less persuasive than the RMD or healthy controls' speeches. No significant differences were found for the cold pressor. Blunted cardiovascular reactivity and impaired recovery in current major depression may be mood-state dependent phenomena and may be more reflective of motivational deficits than deficits in the physiological integrity of the cardiovascular system.

  20. Perspectives on Episodic-like and Episodic Memory

    2013-04-01

    Full Text Available Episodic memory refers to the conscious recollection of a personal experience that contains information on what has happened and also where and when it happened. Recollection from episodic memory also implies a kind of first-person subjectivity that has been termed autonoetic consciousness. Episodic memory is extremely sensitive to cerebral aging and neurodegenerative diseases. In Alzheimer’s disease deficits in episodic memory function are among the first cognitive symptoms observed. Furthermore, impaired episodic memory function is also observed in a variety of other neuropsychiatric diseases including dissociative disorders, schizophrenia and Parkinson disease. Unfortunately, it is quite difficult to induce and measure episodic memories in the laboratory and it is even more difficult to measure it in clinical populations. Presently, the tests used to assess episodic memory function do not comply with even down-sized definitions of episodic-like memory as a memory for what happened, where and when. They also require sophisticated verbal competences and are difficult to apply to patient populations. In this review, we will summarize the progress made in defining behavioral criteria of episodic-like memory in animals (and humans as well as the perspectives in developing novel tests of human episodic memory which can also account for phenomenological aspects of episodic memory such as autonoetic awareness. We will also define basic behavioral, procedural and phenomenological criteria which might be helpful for the development of a valid and reliable clinical test of human episodic memory.

    Full Text Available Aging may lead to cognitive changes, especially in memory. Yet, research suggests that older adults may improve memory performance after training. The present study aimed at evaluating the effects of episodic memory training offered to healthy Brazilian older adults. Fifty seven participants were randomly divided into control group (COG = 26 and experimental group (EXG = 31. The EXG participants completed a pre-test, five sessions of episodic memory training in which they were instructed to categorize grocery lists and pictures, and a post-test. Results indicated that episodic memory training involving learning and practice with categorization promoted significant improvement in episodic memory performance and in better using the trained strategy.

    Objective To explore the big five personality characteristics of the first-episode, treatment-naive major depressive disorder. Method Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI) was used to assess the personality. A comparison was conducted between 112 first-episode, treatment-naive major depressive disorder (MDD) patients and 99 sex-, age- and education level-matched healthy controls (HC). The Hamilton depression scale (HAMD) was used to evaluate patients’symptom. Result Compared with HC, the neuroticism score in MDD group was significantly higher, while the extraversion, openness, agreeableness and conscientiousness were significantly lower. Lo⁃gistic regression analysis showed that MDD was significantly associated with higher neuroticism (OR=1.106, 95%CI:1.029~1.189, P=0.006) and lower extraversion (OR=0.809, 95%CI: 0.733~0.893, P<0.001) and agreeableness (OR=0.870, 95%CI:0.794~0.953, P=0.003). Linear regression showed that the HAMD score was significantly associated with higher neuroticism (B=0.121, P=0.003). The onset age of MDD was significantly associated with conscientiousness (B=0.015, P=0.001). Conclusion This study confirms that the personality of MDD is different from HC. Higher neuroticism is an important personality facets in treatment-naive patients with first-episode MDD. The low conscientiousness might associate with early age of depression onset.%目的:探讨首发未服药抑郁症患者的大五人格特征。方法采用大五人格量表简化版(neuroticism extraversion openness five-factor inventory, NEO-FFI),对112例首发未服药抑郁症患者及99名性别、年龄、文化背景相匹配的正常对照进行大五人格特征评估,汉密尔顿抑郁量表(Hamilton depression scale,HAMD)评定患者的抑郁症状。结果患者组神经质维度得分高于对照组,而外向性、开放性、宜人性及责任感维度得分均低于对照组(P<0.05)。Logistic回归分析示,抑

    Cannabis is the most commonly abused drug among patients with bipolar disorder. Available data has shown that the risk of psychotic disorders increases with the frequency and intensity of cannabis abuse. The present purpose was to review relevant studies to investigate whether cannabis use can be linked to the onset of mania in bipolar disorder. Articles published between 1972 and December 2013 were searched on Medline and PsychInfo using the following keywords: first manic episode, or onset mania, or bipolar disorder and cannabis. Relevant papers cited in the references of selected articles were further considered for inclusion into the review. Lifetime use of cannabis among bipolar patients appears to be around 70% and approximately 30% of patients with a bipolar disorder present a comorbidity of cannabis abuse or dependence. Cannabis use is associated with younger age at onset of first mania and with more frequent depressive or manic episodes, although the evidence is somewhat inconsistent. Likewise cannabis consumption is related to poorer outcome and an increased risk of rapid cycling or mixed episodes. In contrast, neuro-cognitive functioning seems to be positively affected in patients with psychiatric comorbidity. While cannabis use often precedes first manic episodes, the causal direction remains to be determined. Variations in definition of cannabis use/dependence. Lack of controlled studies limiting definite conclusions about a putative causal relationship between cannabis and onset of mania. Further investigations are needed to clarify the relationships between cannabis use and first manic episode. Copyright © 2014 Elsevier B.V. All rights reserved.

    Full Text Available Abstract Background Patients with brief depressive episodes and concurrent rapidly fluctuating psychiatric symptoms do not fit current diagnostic criteria and they can be difficult to diagnose and treat in an acute psychiatric setting. We wanted to study whether these patients had signs of more epileptic or organic brain dysfunction than patients with depression without additional symptomatology. Methods Sixteen acutely admitted patients diagnosed with a brief depressive episode as well as another concurrent psychiatric diagnosis were included. Sixteen patients with major depression served as controls. Three electroencephalographic studies (EEG were visually interpreted and the background activity was also analysed with quantitative electroencephalography (QEEG. Results The group with brief depression and concurrent symptoms had multiple abnormal features in their standard EEG compared to patients with major depression, but they did not show significantly more epileptiform activity. They also had significantly higher temporal QEEG delta amplitude and interhemispheric temporal delta asymmetry. Conclusion Organic brain dysfunction may be involved in the pathogenesis of patients with brief depressive episodes mixed with rapidly fluctuating psychiatric symptoms. This subgroup of depressed patients should be investigated further in order to clarify the pathophysiology and to establish the optimal evaluation scheme and treatment in an acute psychiatric setting.

  9. Are sleep disturbances risk factors for anxiety, depressive and addictive disorders?

    Gillin, J C

    1998-01-01

    This paper reviews recent literature which suggests that sleep disturbance in members of the general population, whether or not they have ever had a formal psychiatric disorder, is a risk factor for the onset of a formal psychiatric diagnosis at a later time. Based upon the current literature, the strongest link is between subjective insomnia, lasting at least 2 weeks, and the later onset of depression. Less well-established data suggest that lifetime reports of at least 2 weeks of insomnia, hypersomnia, or both hypersomnia and insomnia, are risk factors for the later development of depression, anxiety disorders or substance abuse. More tentatively, preliminary data suggest that increasing subjective sleep disturbance may signal a relapse in remitted depressed patients. Sleep disturbances are common manifestations of major depressive and anxiety disorders. Therefore, sleep complaints may be among the most robust prodromal symptoms reflecting partial depressive or anxiety disorders, which eventually declare themselves as full-blown clinical episodes.

    Cognitive Behaviour Therapy for Insomnia (CBT-I) delivered through the Internet is effective as a treatment in reducing insomnia in individuals seeking help for insomnia. CBT-I also lowers levels of depression in this group. However, it is not known if targeting insomnia using CBT-I will lower depressive symptoms, and thus reduce the risk of major depressive episode onset, in those specifically at risk for depression. Therefore, this study aims to examine whether Internet delivery of fully automated self-help CBT-I designed to reduce insomnia will prevent depression. A sample of 1,600 community-dwelling adults (aged 18-64), who screen positive for both subclinical levels of depressive symptoms and insomnia, will be recruited via various media and randomised to either a 9-week online insomnia treatment programme, Sleep Healthy Using The internet (SHUTi), or an online attention-matched control group (HealthWatch). The primary outcome variable will be depression symptom levels at the 6-month post-intervention on the Patient Heath Questionnaire-9 (PHQ-9). A secondary outcome will be onset of major depressive episodes assessed at the 6-month post-intervention using 'current' and 'time from intervention' criteria from the Mini International Neuropsychiatric Interview. This trial is the first randomised controlled trial of an Internet-based insomnia intervention as an indicated preventative programme for depression. If effective, online provision of a depression prevention programme will facilitate dissemination. Australian New Zealand Clinical Trials Registry (ANZCTR), Registration number: ACTRN12611000121965.

    Objective Bipolar Disorder (BP) frequently co-occurs with other psychiatric disorders. We examine whether course of anxiety disorders (ANX), attention deficit hyperactivity disorder (ADHD), disruptive behavior disorders (DBD), and substance use disorders (SUD) influence likelihood of recovery and recurrence of depression and mania in BP youth. Method Weekly ratings of psychiatric disorder intensity were obtained from 413 participants of the Course and Outcome of BP Youth project, followed for an average of 7.75 years. Multiple-event Cox proportional hazards regression analyses examined worsening of comorbid disorders as predictors of mood episode recovery and recurrence. Results Increased severity in ANX and SUD predicted longer time to recovery and less time to next depressive episode, and less time to next manic episode. Multivariate models with ANX and SUD found that significant effects of ANX remained, but SUD only predicted longer time to depression recovery. Increased severity of ADHD and DBD predicted shorter time to recurrence for depressive and manic episodes. Conclusion There are significant time-varying relationships between the course of comorbid disorders and episodicity of depression and mania in BP youth. Worsening of comorbid conditions may present as a precursor to mood episode recurrence or warn of mood episode protraction. PMID:26475572

    Bipolar disorder (BD) is a chronic, frequently comorbid condition characterized by high rates of mood episode recurrence and suicidality. Little is known about prospective longitudinal characterization of BD type II (BD II) versus type I (BD I) in relation to time to depressive recurrence and recovery from major depressive episode. We therefore assessed times to depressive recurrence/recovery in tertiary clinic-referred BD II versus I patients. Outpatients referred to Stanford BD Clinic during 2000-2011 were assessed with Systematic Treatment Enhancement Program for BD (STEP-BD) Affective Disorders Evaluation and with Clinical Monitoring Form during up to 2 years of naturalistic treatment. Prevalence and clinical correlates of bipolar subtype in recovered (euthymic ≥8 weeks) and depressed patients were assessed. Kaplan-Meier analyses assessed the relationships between bipolar subtype and longitudinal depressive severity, and Cox proportional hazard analyses assessed the potential mediators. BD II versus BD I was less common among 105 recovered (39.0 vs. 61.0%, p = 0.03) and more common among 153 depressed (61.4 vs. 38.6%, p = 0.006) patients. Among recovered patients, BD II was associated with 6/25 (24.0%) baseline unfavorable illness characteristics/mood symptoms/psychotropics and hastened depressive recurrence (p = 0.015). Among depressed patients, BD II was associated with 8/25 (33.0%) baseline unfavorable illness characteristics/mood symptoms/psychotropics, but only non-significantly associated with delayed depressive recovery. BD II versus BD I was significantly associated with current depression and hastened depressive recurrence, but only non-significantly associated with delayed depressive recovery. Research on bipolar subtype relationships with depressive recurrence/recovery is warranted to enhance clinical management of BD patients.

    2013-06-01

    Full Text Available Background: The literature describing neurocognitive function in patients with late-life depression (LLD show inconsistent findings in regard to incidence and main deficits. Reduced information processing speed is in some studies found to explain deficits in higher order cognitive function, while other studies report specific deficits in memory and executive function. Our aim was to determine the characteristics of neuropsychological functioning in non-demented LLD patients.Methods; A comprehensive neuropsychological battery was administered to a group of hospitalized LLD patients and healthy control subjects. Thirty-nine patients without dementia, 60 years or older meeting DSM-IV criteria for current episode of major depression, and 18 nondepressed control subjects were included. The patient group was characterized by having a long lasting current depressive episode of late-onset depression and by being non-responders to treatment with antidepressants. Neurocognitive scores were calculated for the domains of information processing speed, verbal memory, visuospatial memory, executive function, and language. Number of impairments (performance below the 10th percentile of the control group per domain for each participant was calculated. Results: Nearly half of the patients had a clinically significant cognitive impairment in at least one neurocognitive domain. Relative to healthy control subjects, LLD patients performed significantly poorer in the domains of information processing speed and executive function. Executive abilities were most frequently impaired in the patient group (39 % of the patients. Even when controlling for differences in processing speed, patients showed more executive deficits than controls. CONCLUSIONS: Controlling for processing speed, patients still showed impaired executive function compared to healthy controls. Reduced executive function thus appears to be the core neurocognitive deficit in LLD. Executive function seems

    2010-10-21

    Inherited episodic neurological disorders are often due to mutations in ion channels or their interacting proteins, termed channelopathies. There are a wide variety of such disorders, from those causing paralysis, to extreme pain, to ataxia. A common theme in these is alteration of action potential properties or synaptic transmission and a resulting increased propensity of the resulting tissue to enter into or stay in an altered excitability state. Manifestations of these disorders are triggered by an array of precipitants, all of which stress the particular affected tissue in some way and aid in propelling its activity into an aberrant state. Study of these disorders has aided in the understanding of disease risk factors and elucidated the cause of clinically related sporadic disorders. The findings from study of these disorders will aid in the diagnosis and efficient targeted treatment of affected patients. Copyright © 2010 Elsevier Inc. All rights reserved.

    To investigate the role of episodic thought about the past and future in moral judgment, we administered a well-established moral judgment battery to individuals with hippocampal damage and deficits in episodic thought (insert Greene et al. 2001). Healthy controls select deontological answers in high-conflict moral scenarios more frequently when they vividly imagine themselves in the scenarios than when they imagine scenarios abstractly, at some personal remove. If this bias is mediated by episodic thought, individuals with deficits in episodic thought should not exhibit this effect. We report that individuals with deficits in episodic memory and future thought make moral judgments and exhibit the biasing effect of vivid, personal imaginings on moral judgment. These results strongly suggest that the biasing effect of vivid personal imagining on moral judgment is not due to episodic thought about the past and future. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

  20. Activated depression: mixed bipolar disorder or agitated unipolar depression?

    Science.gov (United States)

    Swann, Alan C

    2013-08-01

    The combination of depression and activation presents clinical and diagnostic challenges. It can occur, in either bipolar disorder or major depressive disorder, as increased agitation as a dimension of depression. What is called agitation can consist of expressions of painful inner tension or as disinhibited goal-directed behavior and thought. In bipolar disorder, elements of depression can be combined with those of mania. In this case, the agitation, in addition to increased motor activity and painful inner tension, must include symptoms of mania that are related to goal-directed behavior or manic cognition. These diagnostic considerations are important, as activated depression potentially carries increased behavioral risk, especially for suicidal behavior, and optimal treatments for depressive episodes differ between bipolar disorder and major depressive disorder.

    We report a patient with episodic ataxia (presumably of type 2) who developed cerebral oedema secondary to a common infection (presumably viral). Cerebral oedema may be a part of the clinical spectrum of familial episodic ataxia and argues for an overlap with hemiplegic migraine. It is suggested to consider a diagnosis of episodic ataxia or familial hemiplegic migraine in catastrophic reactions to apparent trivial trauma or infection.

  5. The evolution of episodic memory

    2013-01-01

    One prominent view holds that episodic memory emerged recently in humans and lacks a “(neo)Darwinian evolution” [Tulving E (2002) Annu Rev Psychol 53:1–25]. Here, we review evidence supporting the alternative perspective that episodic memory has a long evolutionary history. We show that fundamental features of episodic memory capacity are present in mammals and birds and that the major brain regions responsible for episodic memory in humans have anatomical and functional homologs in other species. We propose that episodic memory capacity depends on a fundamental neural circuit that is similar across mammalian and avian species, suggesting that protoepisodic memory systems exist across amniotes and, possibly, all vertebrates. The implication is that episodic memory in diverse species may primarily be due to a shared underlying neural ancestry, rather than the result of evolutionary convergence. We also discuss potential advantages that episodic memory may offer, as well as species-specific divergences that have developed on top of the fundamental episodic memory architecture. We conclude by identifying possible time points for the emergence of episodic memory in evolution, to help guide further research in this area. PMID:23754432

Conversely, the fast and sustained antidepressant effect of the N-methyl-d-aspartate receptor (NMDAR antagonist ketamine raises vast interest in understanding the role of the glutamate system in mood disorders. Indeed, numerous data support the existence of glutamatergic dysfunction in major depressive disorder (MDD. Drawback to this short-latency therapy is its side effect profile, especially the psychotomimetic action, which seriously hampers the common and widespread clinical use of ketamine. Therefore, there is a substantial need for alternative glutamatergic antidepressants with milder side effects. In this article, we review evidence that implicates NMDARs in the prospective treatment of MDD with focus on rapastinel (formerly known as GLYX-13, a novel synthetic NMDAR modulator with fast antidepressant effect, which acts by enhancing NMDAR function as opposed to blocking it. We summarize and discuss current clinical and animal studies regarding the therapeutic potential of rapastinel not only in MDD but also in other psychiatric disorders, such as obsessive–compulsive disorder and posttraumatic stress disorder. Additionally, we discuss current data concerning the molecular mechanisms underlying the antidepressant effect of rapastinel, highlighting common aspects as well as differences to ketamine. In 2016, rapastinel received the Breakthrough Therapy designation for the treatment

    Full Text Available Abstract Background Depression is often a chronic relapsing condition, with relapse rates of 50-80% in those who have been depressed before. This is particularly problematic for those who become suicidal when depressed since habitual recurrence of suicidal thoughts increases likelihood of further acute suicidal episodes. Therefore the question how to prevent relapse is of particular urgency in this group. Methods/Design This trial compares Mindfulness-Based Cognitive Therapy (MBCT, a novel form of treatment combining mindfulness meditation and cognitive therapy for depression, with both Cognitive Psycho-Education (CPE, an equally plausible cognitive treatment but without meditation, and treatment as usual (TAU. It will test whether MBCT reduces the risk of relapse in recurrently depressed patients and the incidence of suicidal symptoms in those with a history of suicidality who do relapse. It recruits participants, screens them by telephone for main inclusion and exclusion criteria and, if they are eligible, invites them to a pre-treatment session to assess eligibility in more detail. This trial allocates eligible participants at random between MBCT and TAU, CPE and TAU, and TAU alone in a ratio of 2:2:1, stratified by presence of suicidal ideation or behaviour and current anti-depressant use. We aim to recruit sufficient participants to allow for retention of 300 following attrition. We deliver both active treatments in groups meeting for two hours every week for eight weeks. We shall estimate effects on rates of relapse and suicidal symptoms over 12 months following treatment and assess clinical status immediately after treatment, and three, six, nine and twelve months thereafter. Discussion This will be the first trial of MBCT to investigate whether MCBT is effective in preventing relapse to depression when compared with a control psychological treatment of equal plausibility; and to explore the use of MBCT for the most severe recurrent

    2001-08-01

    Episodic memory involves the encoding and storage of memories concerned with unique personal experiences and their subsequent recall, and it has long been the subject of intensive investigation in humans. According to Tulving's classical definition, episodic memory "receives and stores information about temporally dated episodes or events and temporal-spatial relations among these events." Thus, episodic memory provides information about the 'what' and 'when' of events ('temporally dated experiences') and about 'where' they happened ('temporal-spatial relations'). The storage and subsequent recall of this episodic information was thought to be beyond the memory capabilities of nonhuman animals. Although there are many laboratory procedures for investigating memory for discrete past episodes, until recently there were no previous studies that fully satisfied the criteria of Tulving's definition: they can all be explained in much simpler terms than episodic memory. However, current studies of memory for cache sites in food-storing jays provide an ethologically valid model for testing episodic-like memory in animals, thereby bridging the gap between human and animal studies memory. There is now a pressing need to adapt these experimental tests of episodic memory for other animals. Given the potential power of transgenic and knock-out procedures for investigating the genetic and molecular bases of learning and memory in laboratory rodents, not to mention the wealth of knowledge about the neuroanatomy and neurophysiology of the rodent hippocampus (a brain area heavily implicated in episodic memory), an obvious next step is to develop a rodent model of episodic-like memory based on the food-storing bird paradigm. The development of a rodent model system could make an important contribution to our understanding of the neural, molecular, and behavioral mechanisms of mammalian episodic memory.

    Depression is a common disorder with an annual risk of a depressive episode in the United States of 6.6%. Only 30-40% of patients remit with antidepressant monotherapy, leaving 60-70% of patients who do not optimally respond to therapy. Unremitted depressive patients are at increased risk for suicide. Considering the prevalence of treatment resistant depression and its consequences, treatment optimization is imperative. This review summarizes the latest treatment modalities for major depressive disorder including pharmacotherapy, electroconvulsive therapy, repetitive transcranial magnetic stimulation and psychotherapy. Through advancements in research to better understand the pathophysiology of depression, advances in treatment will be realized.

    Although emotional dysfunction is an important aspect of major depressive disorder (MDD), it has rarely been studied in daily life. Peeters, Nicolson, Berkhof, Delespaul, and deVries (2003) observed a surprising mood-brightening effect when individuals with MDD reported greater reactivity to positive events. To better understand this phenomenon, we conducted a multimethod assessment of emotional reactivity to daily life events, obtaining detailed reports of appraisals and event characteristics using the experience-sampling method and the Day Reconstruction Method (Kahneman, Krueger, Schkade, Schwarz, & Stone, 2004) in 35 individuals currently experiencing a major depressive episode, 26 in a minor depressive (mD) episode, and 38 never-depressed healthy controls. Relative to healthy controls, both mood-disordered groups reported greater daily negative affect and lower positive affect and reported events as less pleasant, more unpleasant, and more stressful. Importantly, MDD and mD individuals reported greater reductions in negative affect following positive events, an effect that converged across assessment methods and was not explained by differences in prevailing affect, event appraisals, or medications. Implications of this curious mood-brightening effect are discussed.

    Depression is a multifactorial illness that is highly prevalent among medical students (MS). Chronotypes, which reflect circadian preference in humans, as well as academic stress have been associated with depression in different populations. However, it is not known how chronotype and stress might alone or in combination, associate with depression in MS. Thus, we aimed to evaluate the association between stress, chronotype and depression in MS. In a cross-sectional study, we evaluated a total of 1068 medical students from a public Medical School in Mexico City. The Patient Health Questionnaire-9 (PHQ-9) was used to evaluate depressive symptom severity and the presence of a current depressive episode with a cutoff score of 10 or higher. The Morning-Evening Questionnaire (MEQ) was used to establish chronotype and the Academic Stress Inventory was used to measure perceived academic stress (PAS). We observed that depressive symptom severity was higher in non-morning chronotypes and moderate/severe PAS groups. A factorial ANOVA showed an association between PAS groups and depressive symptom severity. Linear regression showed an association between depressive symptom severity and variables such as PAS scores (p = 0.001), family history of depression (p = 0.001), gender (p = 0.001) and academic year (p = 0.029). Logistic regression analysis showed that evening chronotype (OR: 2.3, 95% CI: 1.2-4.3, p = 0.01) and severe PAS (OR: 4.4, 95% CI: 2.8-7.0, p = 0.0001) were associated with depression. Further, MS with the combination of severe PAS and morning (OR: 5.9, 95% CI: 1.6-22.2, p = 0.01), intermediate (OR: 7.5, 95% CI: 2.3-24.4, p = 0.001) or evening (OR: 10.6, 95% CI: 2.8-40.0, p = 0.001) chronotypes showed a greater association with depression than any PAS or chronotype group alone. Being female, perceiving restricted or limited economic resources, having severe scores of academic stress, and evening chronotype were associated with an increased probability to suffer a

    This study examined whether deficits in dealing with daily problems emerge before a depressive episode (i.e., pre-existing vulnerability) or after a depressive episode (i.e., psychosocial scar). Participants completed a 30-day daily diary in which they reported their most negative event of the day, their appraisals of that event, and their mood. Three years later, they completed a structured depression interview. The sample consisted of 350 college students, 24 of whom had a past history of depression and 54 of whom experienced a depressive episode subsequent to dairy completion. Multilevel modeling revealed that students with past depression blamed others more than the never-depressed and those with subsequent depression, which supported the scar hypothesis. In support of the vulnerability hypothesis, as compared to the never-depressed group, participants with past depression demonstrated steeper declines in positive mood on more stressful days but did not significantly differ from the subsequent depression group. Overall, our findings do not provide clear support for either hypothesis; however, this study is the first to use a daily diary design to directly compare individuals with past depression to individuals who would subsequently experience depression.

However, predictors of response to ECT have not been adequately studied using the Montgomery and Åsberg Depression Rating Scale, especially in older patients with treatment-resistant depression.Methods: This study included 18 Japanese patients who fulfilled the Diagnostic and Statistical Manual of Mental Disorders Fourth Edition Text Revision criteria for a diagnosis of major depressive disorder or bipolar disorder with a current major depressive episode, and met the definition of treatment-resistant depression outlined by Thase and Rush, scoring ≥21 on the Montgomery and Åsberg Depression Rating Scale. The three-factor model of the Montgomery and Åsberg Depression Rating Scale was used for analysis. Factor 1 was defined by three items, factor 2 by four items, and factor 3 by three items, representing dysphoria, retardation, and vegetative symptoms, respectively. ECT was performed twice a week for a total of six sessions using a Thymatron System IV device with the brief pulse technique. Clinical responses were defined on the basis of a ≥50% decrease in total pretreatment Montgomery and Åsberg Depression Rating Scale scores.Results: The mean pretreatment factor 2 score for responders (n = 7 was significantly lower than that for nonresponders (n = 11. Furthermore, a significant difference in mean factor 3 score between responders and nonresponders was observed one week after six sessions of ECT, indicating a time lag of response. No significant differences were observed for age, number of previous episodes, and duration of the current episode between responders and

  5. Key features of human episodic recollection in the cross-episode retrieval of rat hippocampus representations of space.

    Full Text Available Neurophysiological studies focus on memory retrieval as a reproduction of what was experienced and have established that neural discharge is replayed to express memory. However, cognitive psychology has established that recollection is not a verbatim replay of stored information. Recollection is constructive, the product of memory retrieval cues, the information stored in memory, and the subject's state of mind. We discovered key features of constructive recollection embedded in the rat CA1 ensemble discharge during an active avoidance task. Rats learned two task variants, one with the arena stable, the other with it rotating; each variant defined a distinct behavioral episode. During the rotating episode, the ensemble discharge of CA1 principal neurons was dynamically organized to concurrently represent space in two distinct codes. The code for spatial reference frame switched rapidly between representing the rat's current location in either the stationary spatial frame of the room or the rotating frame of the arena. The code for task variant switched less frequently between a representation of the current rotating episode and the stable episode from the rat's past. The characteristics and interplay of these two hippocampal codes revealed three key properties of constructive recollection. (1 Although the ensemble representations of the stable and rotating episodes were distinct, ensemble discharge during rotation occasionally resembled the stable condition, demonstrating cross-episode retrieval of the representation of the remote, stable episode. (2 This cross-episode retrieval at the level of the code for task variant was more likely when the rotating arena was about to match its orientation in the stable episode. (3 The likelihood of cross-episode retrieval was influenced by preretrieval information that was signaled at the level of the code for spatial reference frame. Thus key features of episodic recollection manifest in rat hippocampal

  7. Emotional stress-reactivity and positive affect among college students: the role of depression history.

    Multiple theories posit that people with a history of depression are at higher risk for a depressive episode than people who have never experienced depression, which may be partly due to differences in stress-reactivity. In addition, both the dynamic model of affect and the broaden-and-build theory suggest that stress and positive affect interact to predict negative affect, but this moderation has never been tested in the context of depression history. The current study used multilevel modeling to examine these issues among 1,549 college students with or without a history of depression. Students completed a 30-day online diary study in which they reported daily their perceived stress, positive affect, and negative affect (including depression, anxiety, and hostility). On days characterized by higher than usual stress, students with a history of depression reported greater decreases in positive affect and greater increases in depressed affect than students with no history. Furthermore, the relations between daily stress and both depressed and anxious affect were moderated by daily positive affect among students with remitted depression. These results indicate that students with a history of depression show greater stress-reactivity even when in remission, which may place them at greater risk for recurrence. These individuals may also benefit more from positive affect on higher stress days despite being less likely to experience positive affect on such days. The current findings have various implications both clinically and for research on stress, mood, and depression. (PsycINFO Database Record (c) 2014 APA, all rights reserved).

This study sought to evaluate the effects of a single dose of AYA in six volunteers with a current depressive episode. Methods: Open-label trial conducted in an inpatient psychiatric unit. Results: Statistically significant reductions of up to 82% in depressive scores were observed between baseline and 1, 7, and 21 days after AYA administration, as measured on the Hamilton Rating Scale for Depression (HAM-D, the Montgomery-Åsberg Depression Rating Scale (MADRS, and the Anxious-Depression subscale of the Brief Psychiatric Rating Scale (BPRS. AYA administration resulted in nonsignificant changes in Young Mania Rating Scale (YMRS scores and in the thinking disorder subscale of the BPRS, suggesting that AYA does not induce episodes of mania and/or hypomania in patients with mood disorders and that modifications in thought content, which could indicate psychedelic effects, are not essential for mood improvement. Conclusions: These results suggest that AYA has fast-acting anxiolytic and antidepressant effects in patients with a depressive disorder.

    Full Text Available BACKGROUND: The clinical features of type 2 diabetes may differ depending on whether first depression episode precedes or follows the diagnosis of diabetes. METHODS: Type 2 patients from the observational community-based Fremantle Diabetes Study Phase II underwent assessment of lifetime depression using the Brief Lifetime Depression Scale (developed and validated for this study supplemented by information on current depression symptoms (Patient Health Questionnaire, 9-item version and use of antidepressants. Patients were categorized as never depressed (Group 1, having had depression before diabetes diagnosis (Group 2, diagnosed with depression and diabetes within 2 years of each other (Group 3 and having depression after diabetes diagnosis (Group 4. RESULTS: Of 1391 patients, 20.8% were assigned to Group 2, 6.0% to Group 3 and 14.5% to Group 4. In Group 2, depression occurred a median 15.6 years before diabetes onset at age 37.2±14.7 years. These patients had similar clinical characteristics to never depressed patients except for reduced self-care behaviours and having more symptomatic peripheral arterial disease. In Group 4, depression occurred a median 9.9 years after diabetes onset at age 59.8±13.0 years. These patients had long duration diabetes, poor glycaemic control, more intensive management and more diabetic complications. Group 4 patients had more current depression than Group 2 but were less likely to be receiving antidepressants. CONCLUSIONS/INTERPRETATION: The clinical features of depression and type 2 diabetes are heterogeneous depending on their temporal relationship. There may be corresponding differences in the pathogenesis of depression in diabetes that have implications for diagnosis and management.

    Classical monoaminergic antidepressants show several disadvantages, such as protracted onset of therapeutic action. Conversely, the fast and sustained antidepressant effect of the N-methyl-d-aspartate receptor (NMDAR) antagonist ketamine raises vast interest in understanding the role of the glutamate system in mood disorders. Indeed, numerous data support the existence of glutamatergic dysfunction in major depressive disorder (MDD). Drawback to this short-latency therapy is its side effect profile, especially the psychotomimetic action, which seriously hampers the common and widespread clinical use of ketamine. Therefore, there is a substantial need for alternative glutamatergic antidepressants with milder side effects. In this article, we review evidence that implicates NMDARs in the prospective treatment of MDD with focus on rapastinel (formerly known as GLYX-13), a novel synthetic NMDAR modulator with fast antidepressant effect, which acts by enhancing NMDAR function as opposed to blocking it. We summarize and discuss current clinical and animal studies regarding the therapeutic potential of rapastinel not only in MDD but also in other psychiatric disorders, such as obsessive–compulsive disorder and posttraumatic stress disorder. Additionally, we discuss current data concerning the molecular mechanisms underlying the antidepressant effect of rapastinel, highlighting common aspects as well as differences to ketamine. In 2016, rapastinel received the Breakthrough Therapy designation for the treatment of MDD from the US Food and Drug Administration, representing one of the most promising alternative antidepressants under current investigation.

    Full Text Available Overgeneral autobiographical memory (AM manifests in individuals with major depressive disorder (MDD tested during depressed (dMDD or remitted phases (rMDD, and healthy individuals at high-risk (HR for developing MDD. The current study aimed to elucidate differences in hemodynamic correlates of AM recall between rMDDs, HRs, and controls (HCs to identify neural changes following previous depressive episodes without the confound of current depressed mood. HCs, HRs, and unmedicated rMDDs (n = 20/group underwent fMRI while recalling AMs in response to emotionally valenced cue words. HRs and rMDDs recalled fewer specific and more categorical AMs relative to HCs. During specific AM recall, HRs had increased activity relative to rMDDs and HCs in left ventrolateral prefrontal cortex (VLPFC and lateral orbitofrontal cortex. During positive specific AM recall, HRs and HCs had increased activity relative to rMDDs in bilateral dorsomedial prefrontal cortex (DMPFC and left precuneus. During negative specific AM recall HRs and HCs had increased activity in left VLPFC and right DMPFC, while rMDDs had increased activity relative to HRs and HCs in right DLPFC and precuneus. Differential recruitment of medial prefrontal regions implicated in emotional control suggests experiencing a depressive episode may consequently reduce one’s ability to regulate emotional responses during AM recall.

    Suicide is a relatively common outcome along the course of bipolar disorder. Studies have shown a positive correlation between ideation or attempts of suicide and higher insight in schizophrenic patients. Nevertheless there are still few studies that evaluate the relationship between suicide and insight in mood disorders. Evaluate the relationship between insight and suicidal ideation or behavior in bipolar depression. A group of 165 bipolar patients were followed up along 1 year. Each patient's mood was assessed in every consultation according to DSM-IV-TR criteria. Suicidal ideation and behavior were prospectively assessed through item 3 of HAM-D whenever a major depressive episode was diagnosed. Insight was evaluated through the Insight Scale for Affective Disorders. A history of suicidal attempts was associated with worse insight in 60 patients with one episode of bipolar depression. The difference remained even when the supposed effect of depression over insight was controlled. No correlation between current suicidal ideation and insight level was found though. Our results suggest that a history of suicide attempts may correlate with higher impairment of insight in bipolar depression. No relationship was found between current suicidal ideation and insight.

    2015-01-01

    Whereas self-criticism has been proposed as an important risk factor for major depressive disorder (MDD), self-compassion has been suggested as a resilience factor that protects against the development and maintenance of depressive episodes. This study aimed to test the hypothesis that frequent self-criticism and low habitual self-compassion are related to concurrent depression and to vulnerability to depression by comparing groups of currently, remitted and never depressed individuals. As expected, both currently and remitted depressed individuals reported higher levels of self-criticism and lower self-compassion than never depressed controls. Individual differences in self-criticism and self-compassion were related to depression status above and beyond additional potential correlates of MDD (i.e., perfectionistic beliefs and cognitions, rumination and overall adaptive emotion regulation). The findings provide support for the idea that increased self-criticism and decreased self-compassion place certain individuals at increased risk for experiencing depression repeatedly or chronically over the course of their lives.

    This study aims to establish if adult patients with major depressive disorder (MDD) and childhood Attention Deficit/Hyperactivity disorder (ADHD) symptoms would be more frequently within the bipolar spectrum than depressed patients without childhood ADHD. This study was carried out in outpatients recruited by psychiatrists in private practice, with 3963 participants being included in the final sample. Clinicians filled out questionnaires about current depressive symptoms in their patients, lifetime bipolar symptoms, global assessment of functioning and parental history of both major depression and bipolar disorder. Patients assessed current level of anxiety and depressive symptoms and antecedents of childhood ADHD symptoms. Depressed adults with significant childhood ADHD symptoms had a specific pattern of their major depressive episode compared to depressed patients without such symptoms. Subjects with childhood ADHD symptoms were more likely to report lifetime symptoms of mania/hypomania and to have a parent with type I or II bipolar disorder. The developmental trajectories of familial risk for lifetime bipolar symptoms showed that parental bipolar disorder influenced lifetime bipolar symptoms both through a direct pathway and an indirect pathway involving childhood ADHD symptoms. Childhood ADHD and number of depressive symptoms both made direct contributions to lifetime bipolar symptoms. Copyright © 2017 Elsevier Ireland Ltd. All rights reserved.

    Examine the effects of the timing of parents' relationship instability on adolescent sexual and mental health. We assessed whether the timing of parents' relationship instability predicted adolescents' history of sexual partnerships (SP) and major depressive episodes. Multivariate logistic regression analyses controlled for potential mediators related to parenting and the family, including parent knowledge of activities, parent-child relationship quality, number of parents' post-separation relationship transitions, and number of available caregivers. Participants were assessed annually from age 5 through young adulthood as part of a multisite community sample (N = 585). Participants who experienced parents' relationship instability before age 5 were more likely to report SP at age 16 (odds ratio [OR](adj) = 1.58) or an episode of major depression during adolescence (OR(adj) = 2.61). Greater parent knowledge at age 12 decreased the odds of SP at age 16, but none of the hypothesized parenting and family variables statistically mediated the association between early instability and SP or major depressive episode. These results suggest that experiencing parents' relationship instability in early childhood is associated with sexual behavior and major depression in adolescence, but these associations are not explained by the parenting and family variables included in our analyses. Limitations of the current study and implications for future research are discussed. Copyright © 2010 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

    Emotional inertia refers to the degree to which a person's current emotional state is predicted by their prior emotional state, reflecting how much it carries over from one moment to the next. Recently, in a cross-sectional study, we showed that high inertia is an important characteristic of the emotion dynamics observed in psychological maladjustment such as depression. In the present study, we examined whether emotional inertia prospectively predicts the onset of first-episode depression during adolescence. Emotional inertia was assessed in a sample of early adolescents (N = 165) based on second-to-second behavioral coding of videotaped naturalistic interactions with a parent. Greater inertia of both negative and positive emotional behaviors predicted the emergence of clinical depression 2.5 years later. The implications of these findings for the understanding of the etiology and early detection of depression are discussed. (PsycINFO Database Record (c) 2012 APA, all rights reserved).

    The Northern Hemisphere cryosphere's response to the monotonic decline in summer insolation through the Holocene has been irregular expansion, interrupted by periods of retreat, culminating in the Little Ice Age, when most glaciers attained their maximum late Holocene dimensions. This non-linear response to near-linear forcing implies other factors modulate the radiative effects of the regular insolation decline. Understanding how the Earth system accomplishes this modulation is relevant to the development of reliable models for future climate change. Accurately dating the onset of persistent summer coolings across the Arctic is a first step toward developing this understanding. Here we report 52 precise radiocarbon dates on rooted plants emerging from beneath receding glaciers on Svalbard that define times when colder summers led to snowline depression and an expanded cryosphere. The earliest persistent depression of snowline documented by our dates occurred between 4.0 and 3.4 ka, but with little additional summer cooling until early in the first millennium AD. Episodes of subsequent summer cooling were centered on 240-340, 410-540 and 670-770 AD, followed by additional cooling between 1000 and 1230 AD, and between 1300 and 1470 AD. Cooling that occurred after 1470 AD, includes of the Little Ice Age when the Svalbard cryosphere reached its maximum Neoglacial dimensions. We suggest that in addition to insolation forcing, irregular reductions in the strength of the North Atlantic Current and expansions of Arctic Ocean sea ice were dominant factors that led to episodic snowline depression over Svalbard, but the extent to which these changes are linked to radiative forcing from volcanism or solar irradiance as opposed to unforced variability remains unclear. The widespread exposure of entombed plants dating from the first millennium AD suggests that Svalbard's average summer temperatures of the past century now exceed those of any century since at least 700 AD

    Depression is often a chronic relapsing condition, with relapse rates of 50-80% in those who have been depressed before. This is particularly problematic for those who become suicidal when depressed since habitual recurrence of suicidal thoughts increases likelihood of further acute suicidal episodes. Therefore the question how to prevent relapse is of particular urgency in this group. This trial compares Mindfulness-Based Cognitive Therapy (MBCT), a novel form of treatment combining mindfulness meditation and cognitive therapy for depression, with both Cognitive Psycho-Education (CPE), an equally plausible cognitive treatment but without meditation, and treatment as usual (TAU). It will test whether MBCT reduces the risk of relapse in recurrently depressed patients and the incidence of suicidal symptoms in those with a history of suicidality who do relapse. It recruits participants, screens them by telephone for main inclusion and exclusion criteria and, if they are eligible, invites them to a pre-treatment session to assess eligibility in more detail. This trial allocates eligible participants at random between MBCT and TAU, CPE and TAU, and TAU alone in a ratio of 2:2:1, stratified by presence of suicidal ideation or behaviour and current anti-depressant use. We aim to recruit sufficient participants to allow for retention of 300 following attrition. We deliver both active treatments in groups meeting for two hours every week for eight weeks. We shall estimate effects on rates of relapse and suicidal symptoms over 12 months following treatment and assess clinical status immediately after treatment, and three, six, nine and twelve months thereafter. This will be the first trial of MBCT to investigate whether MCBT is effective in preventing relapse to depression when compared with a control psychological treatment of equal plausibility; and to explore the use of MBCT for the most severe recurrent depression--that in people who become suicidal when depressed.

    It has been suggested that episodic tremor and slip (ETS), the weak shaking not associated with measurable earthquakes, could trigger nearby earthquakes. However, this had not been confirmed until recently. Vidale et al. monitored seismicity in the 4-month period around a 16-day episode of episodic tremor and slip in March 2010 in the Cascadia region. They observed five small earthquakes within the subducting slab during the ETS episode. They found that the timing and locations of earthquakes near the tremor suggest that the tremor and earthquakes are related. Furthermore, they observed that the rate of earthquakes across the area was several times higher within 2 days of tremor activity than at other times, adding to evidence of a connection between tremor and earthquakes.

    Objective To reevaluate major depressive episodes' treatment outcome at 8 weeks and 2 years after transitory remission ( remission time lasted 1 - 7 weeks ) based on the redefinition of treatment outcomes for major depressive episodes( MDE ) and to explore the predictive factors for outcomes. Methods A 2-year open, prospective and natural study was conducted on 84 inpatients with MDE who had achieved transitory remission at discharge and their outcomes were assessed using 24-item Hamilton depression rating scale ( HAMD ), Bech-Rafaelsen mania scale( BRMS ) and self-made questionnaire. Results At 8 weeks after discharge, 46.4% ( 39/84 ) patients remained in remission ( remission time lasted 8 weeks or longer ) , 10.7% ( 9/84 ) patients experienced subthreshold episode, 21.4% ( 18/84 ) patients presented residual symptoms and 21.4% ( 18/84 ) patients relapsed. At 2 years after discharge, 39.3% ( 33/84 )patients completely recovered, 25.0%( 21/84 )patients partially recovered, 35.7% ( 30/84 )patients had a chronic course or frequently recurred.Binary logistic regression analysis showed that remission at 8 weeks after discharge was associated with illness duration( P =0.047, OR =0.89,β =-0.12 ), and recovery at 2 years after discharge was associated with the remission at 8 weeks after discharge ( P < 0.001,OR = 109.97 ,β = 4.70 ) and treatment compliance (P=0.002, OR =0.23 , β=-1.46 ). Age,sex, comorbidity, psychotic features, numher of episodes, illness severity, family history, unipolar or bipolar disorder didn't significantly affect the short-term and long-term treatment outcomes ( P > 0.05 ). Conclusions Remission should bethe treatment goal for patients with acute MDE and good long-term outcomes for patients with MDE depend on an early,complete and whole-course treatment.%目的 基于对重性抑郁发作疗效的重新定义,重新评价重性抑郁发作暂时缓解后8周和2年后的疗效并探讨其预测因素.方法

    The aim of this study was to examine the performance of a group of patients with lesions of the prefrontal cortex in directed forgetting in episodic memory, i.e. the capacity to actively forget irrelevant information. Four lists of 24 intermixed to-be-remembered (TBR) and to-be-forgotten (TBF) words were presented for retention. Restricted (TBR only) and unrestricted (TBR and TBF) recall were tested. The results showed that prefrontal patients presented with a general reduction in episodic memory but a normal ability to selectively recall the TBR items during restricted and unrestricted recall. These results are consistent with previous reports of intact directed forgetting in frontal patients and are discussed in terms of their implications for the current debate on the neural substrate of executive functions.

    Full Text Available Abstract Background To study late-life depression and its unfavourable course and co morbidities in The Netherlands. Methods We designed the Netherlands Study of Depression in Older Persons (NESDO, a multi-site naturalistic prospective cohort study which makes it possible to examine the determinants, the course and the consequences of depressive disorders in older persons over a period of six years, and to compare these with those of depression earlier in adulthood. Results From 2007 until 2010, the NESDO consortium has recruited 510 depressed and non depressed older persons (≥ 60 years at 5 locations throughout the Netherlands. Depressed persons were recruited from both mental health care institutes and general practices in order to include persons with late-life depression in various developmental and severity stages. Non-depressed persons were recruited from general practices. The baseline assessment included written questionnaires, interviews, a medical examination, cognitive tests and collection of blood and saliva samples. Information was gathered about mental health outcomes and demographic, psychosocial, biological, cognitive and genetic determinants. The baseline NESDO sample consists of 378 depressed (according to DSM-IV criteria and 132 non-depressed persons aged 60 through 93 years. 95% had a major depression and 26.5% had dysthymia. Mean age of onset of the depressive disorder was around 49 year. For 33.1% of the depressed persons it was their first episode. 41.0% of the depressed persons had a co morbid anxiety disorder. Follow up assessments are currently going on with 6 monthly written questionnaires and face-to-face interviews after 2 and 6 years. Conclusions The NESDO sample offers the opportunity to study the neurobiological, psychosocial and physical determinants of depression and its long-term course in older persons. Since largely similar measures were used as in the Netherlands Study of Depression and Anxiety (NESDA; age

    The episodic ataxias are autosomal dominant disorders usually beginning in the first two decades of life. Episodic ataxia type 1 (EA1) is characterized by brief episodes of ataxia, typically lasting seconds, and interictal myokymia, while episodic ataxia type 2 (EA2) is manifested by longer episodes of ataxia (hours) with interictal nystagmus. The EA1 gene (KCNA1) codes for the six transmembrane segments (S1 to S6) of the Kv1.1 potassium channel subunit and the EA2 gene (CACNA1A) encodes for the Ca(v)2.1 subunit of the P/Q calcium channel complex. EA1 mutations are always missense while most EA2 mutations disrupt the reading frame. Studies of the biophysical properties of the mutant Kv1.1 and Ca(v)2.1 channels in Xenopus oocytes and mammalian cell lines demonstrate clear physiologic consequences of the genetic mutations although no consistent pattern for genotype-phenotype correlation has emerged. Genetic testing for EA1 and EA2 is available, but since no single mutation is prominent for either KCNA1 or CACNA1A, all of the coding regions of the genes need to be screened for mutations. Acetazolamide can be dramatic in controlling episodes of ataxia with EA2 but is typically less beneficial with EA1. 2012 Elsevier B.V. All rights reserved.

    their predictive value for the onset of clinical depressive episodes needs further investigation. Familial and individual vulnerability is likely to heighten the depressogenic impact of life events and psycho-social adversity. Prevention interventions have been developed in the United States for children and adolescents at-risk for depression. In France, clinicians witness growing demands from families with affective illness concerned with risk of parent-child transmission of depressive vulnerability, prevention and early identification of symptoms. To meet this kind of emerging needs and to prevent family dysfunction, a preventive program targets offspring of depressed parents and uses clinician-based family approaches. Family and individual sessions aim a better understanding of illness experience and encourage the parents to identify and foster resilience in their children. Another type of preventive intervention focuses on children and adolescents with subclinical depressive symptoms, eventually associated with behavioral problems ou high level of parental conflict, recruited in school settings. These school-based interventions combine cognitive and social problem-solving techniques. Both familial and school-based preventive interventions have proven applicable and promising in high-risk children and adolescents. Perspectives are more systematic identification of risk groups, including youngsters with past or current non affective symptoms who might benefit from depression prevention, long-term evaluation and cross-cultural applications of prevention programs.

    Insomnia and depressive disorders are significant health problems in the elderly. Persistent insomnia is a risk factor for the development of new-onset and recurrent major depressive disorder (MDD). Less clear is whether persistent insomnia may perpetuate MDD andlor dysthymia. The present longitudinal study examines the relationship of insomnia to the continuation of depression in the context of an intervention study in elderly subjects. Data were drawn from Project IMPACT, a multisite intervention study, which enrolled 1801 elderly patients with MDD and/or dysthymia. In the current study, subjects were assigned to an insomnia-status group (Persistent, Intermediate, and No Insomnia) based on insomnia scores at both baseline and 3-month time points. Logistic regressions were conducted to determine whether Persistent Insomnia was prospectively associated with increased risk of remaining depressed and/or achieving a less than 50% clinical improvement at 6 and at 12 months compared with the No Insomnia reference group. The Intermediate Insomnia group was compared with the other 2 groups to determine whether a dose-response relationship existed between insomnia type and subsequent depression. Eighteen primary clinics in 5 states. Older adults (60+) with depression. Overall, patients with persistent insomnia were 1.8 to 3.5 times more likely to remain depressed, compared with patients with no insomnia. The findings were more robust in patients receiving usual care for depression than in patients receiving enhanced care. Findings were also more robust in subjects who had MDD as opposed to those with dysthymia alone. These findings suggest that, in addition to being a risk factor for a depressive episode, persistent insomnia may serve to perpetuate the illness in some elderly patients and especially in those receiving standard care for depression in primary care settings. Enhanced depression care may partially mitigate the perpetuating effects of insomnia on depression.

    Depression is highly prevalent in patients with schizophrenia and is associated with significant clinical consequences, but there is no known biomarker for depression in schizophrenia. One of the putative neurochemical biomarkers for depression in major depressive disorder (MDD) is reduced cerebral concentration of myo-Inositol. We examined whether myo-Inositol levels provide a potential marker for depressive symptoms in schizophrenia similar to that in MDD and are informative regarding causal biological pathways underlying both depression and schizophrenia. We used proton magnetic resonance spectroscopy to examine myo-Inositol levels in the anterior cingulate cortex (ACC) in 59 schizophrenia spectrum disorder (SSD) patients and 69 matched community comparison participants. Participants completed the Maryland Trait and State Depression (MTSD) scale to measure symptoms of depression experienced around time of assessment ('State' subscale) and longitudinally ('Trait' subscale). Myo-Inositol in the ACC was negatively correlated with MTSD-Trait scores in both patients (ρ=-0.336, p=0.009) and community comparison samples (ρ=-0.328, p=0.006). Furthermore, patients with a diagnosis of schizoaffective disorder or a history of at least one major depressive episode had lower levels of myo-Inositol compared with schizophrenia patients without a current or past affective diagnosis (p=0.012). Since reduced brain myo-Inositol is associated with MDD, myo-Inositol may be a biochemical marker of depressive mood symptoms across diagnostic boundaries. If confirmed, this finding may aid investigation of the pathophysiology and therapeutics of depression common between depression, schizophrenia and other psychiatric diagnoses.

    For the first time, the present study explores self-experienced vulnerability, prodromal symptoms and coping strategies preceding schizophrenic and affective episodes. 33 schizophrenic and 29 depressive patients were assessed retrospectively for preepisodic alterations by means of the "Bonn Scale for the Assessment of Basic Symptoms- BSABS" after complete recovery from the acute episode. 97% of the schizophrenic and 93% of the depressive patients showed preepisodic alterations. In the schizophrenic group the first alteration occurred with a median of 10 weeks and in the depressive group with a median of 18 weeks before the onset of the acute episode. With regard to self-experienced vulnerability depressive cases were significantly less tolerant to stress, i.e work under time pressure or unusual, unexpected requirements. With regard to prodromal symptoms schizophrenics showed significantly more often interpersonal irritation and certain perception and thought disturbances, whereas depressive patients reported more often adynamia and certain disturbances of proprioception. 73% of the schizophrenic patients and 90% of the depressive patients reacted to early symptoms with coping strategies. The preepisodic alterations in schizophrenic patients could be described in terms of mild psychotic productivity, early symptoms of depressive patients could be described as a mild depressive syndrome. Prospective studies are necessary to show if assessment of mild psychotic productivity could be used for early diagnosis and early intervention in schizophrenia.

    The heterogeneity of mood states in bipolar disorders leads to some confusion in diagnostic and therapeutic strategies. Apart from the classical syndromes characterizing euphoric mania and melancholic depression, recent literature has pointed to alternative mood states associating both manic and depressive symptoms. This resulted in the definition of various syndromes including mixed states, dysphoric mania, agitated depression and more recently the depressive mixed state. This consequently raises the question of the best therapeutic strategies. As the boundaries between the various states associating both depressive and manic symptoms have yet to be clarified, there is a need to further discuss whether dimensional rather than categorical approaches could help to further refine their definitions and define the best therapeutic strategies. As stated by Kraepelin, mood episodes in manic-depressive illness were defined according to three dimensions: mood, cognitive processes, and motor and motivational drive. Cognitive and motor processes were regarded as quantitative items whose alterations may correspond to either an increase or a decrease. The current definitions are far from this dimensional approach. Thus, the current diagnostic criteria make it difficult to define mixed states. Such poorly convincing diagnostic criteria may account for the description of many other states exhibiting both manic and depressive symptoms. A dimensional approach could be useful to define mood states in bipolar disorders. These dimensions should progressive, from inhibition to excitation. Because tonality affects is not a dimension, the emotional reactivity (hyper-reactivity versus hypo-reactivity) represents an additional dimension that would help characterize these states better.

    2010-12-01

    Full Text Available A crucial part of the treatment of depression is the prevention of relapse and recurrence. Psychological interventions, especially cognitive behavior therapy (CBT are helpful in preventing relapse and recurrence in depression. The effectivity of four types of relapse prevention cognitive behavior therapy strategies will be addressed, i.e. acute prophylactic cognitive behavior therapy, continuation cognitive behavior therapy, sequential cognitive behavior therapy and cognitive behavior therapy in partial remission.Specific ingredients of three sequential cognitive behavior therapy programs (well-being cognitive therapy, preventive cognitive therapy, and mindfulness-based cognitive therapy will be discussed as applied after remission in patients that experienced previous depressive episodes. Sequential preventive cognitive behavior therapy after acute treatment may be an attractive alternative treatment for many patients who currently use antidepressants for years and years to prevent relapse and recurrence. This is an extremely challenging issue to research thoroughly. Future studies must rule out what intervention for whom is the best protection against relapse and recurrence in depression.

    Children and adolescents with bipolar disorder may have depression as the presenting mood state. It is important for clinicians to distinguish between unipolar and bipolar depression in youth. Depressive episodes are common during the course of bipolar illness in children and adolescents. Evidence-based treatments are needed to guide clinicians' treatment decisions for youth with bipolar depression. This article reviews the prevalence, diagnosis, course, and treatment of bipolar depression in youth, and emphasizes the need for large, controlled treatment studies in the pediatric population.

    to a lesser extent are preceded by stressful life events. Clinical features do not differ between depressions with or without prior stressful life events. Certain genetic variations in the serotonin receptor system seem to increase the risk of developing depression in relation to experiencing stressful life......The aim of the present review was to present clinical aspects of recent research in genes, the experience of stressful life events and depression. 60-70% experience a moderate to severe stressful life event half a year prior to the first onset of depression, whereas later depressive episodes...

    The purpose of the episodic memory test and the caregiver's episodic memory test is to evaluate episodic memory according to its definition in a way that is feasible for families and achieves high degrees of sensitivity and specificity. We administered a test consisting of 10 questions about episodic events to 332 subjects, of whom 65 had Alzheimer's disease (AD), 115 had amnestic MCI (aMCI) and 152 showed no cognitive impairment according to Reisberg's global deterioration scale (GDS). We calculated the test's sensitivity and specificity to distinguish AD from episodic aMCI and from normal ageing. The area under the ROC curve for the diagnosis of aMCI was 0.94 and the best cut-off value was 20; for that value, sensitivity was 89% and specificity was 82%. For a diagnosis of AD, the area under the ROC curve was 0.99 and the best cut-off point was 17, with a sensitivity of 98% and a specificity of 91%. A subsequent study using similar methodology yielded similar results when the test was administered directly by the caregiver. The episodic memory test and the caregiver's episodic memory test are useful as brief screening tools for identifying patients with early-stage AD. It is suitable for use by primary care medical staff and in the home, since it can be administered by a caregiver. The test's limitations are that it must be administered by a reliable caregiver and the fact that it measures episodic memory only. Copyright © 2012 Sociedad Española de Neurología.
