    Autism is a developmental disorder affecting social relationships, communication and flexibility of thought. These three basic aspects of autism may present in many different forms and degrees. Therefore autism should be considered to be a spectrum of autistic disorders rather than a single strictly defined condition. The spectrum of autistic disorders extends from intelligent individuals with acceptable social integration, to severely retarded patients with scarcely any social interaction. Language is almost always affected either in its formal aspects or in its usage. Autistic linguistic disorders form a specific language disorder (developmental dysphasia) and a pragmatic disorder linked both to the primary language problem and to the social cognitive deficit. We discuss the different linguistic syndromes observed in autistic patients with special emphasis on the semantic-pragmatic disorder. PMID:10778500

  6. The savant syndrome and autistic disorder.

    1999-12-01

    Savant syndrome, characterized by remarkable islands of mental ability in otherwise mentally handicapped persons, may occur in autistic as well as nonautistic individuals. Overall, approximately 10% of autistic persons exhibit savant abilities; roughly 50% of those with savant syndrome have autism, and the remaining 50% have other forms of developmental disability. Most commonly, savant syndrome takes the form of extraordinary musical abilities, but may also include calendar-calculation, artistic, mathematical, spatial, mechanical, and memory skills. While savant syndrome was first described more than a century ago, only recently have researchers begun to employ a more uniform nomenclature and more standardized testing in an effort to compare the abilities of savants with those of normal persons. Males show signs of savant syndrome approximately four times more often than females. Along with imaging study findings, this fact suggests the presence of a developmental disorder involving left-brain damage with right-brain compensation. PMID:18311109

  7. Audio Linguistic Disorders in Autistic Children

    International Nuclear Information System (INIS)

    Objective: To explore auditory function abnormalities and language disorder in autistic children. Twelve children with criteria of infantile autism were tested using Pure Tone Audiometry (PTA), Immitancemetry, Transient Evoked Otoacoustic Emission Test (TEOAE), Auditory Brainstem Response (ABR), Standardized Arabic Test of Early Language Development (for both receptive and expressive language). For comparison twlive normal children were chosen as control group. Statistically significant increase in hearing threshold level for the autistic children at low frequency region 250, 500 and 1000 Hz, significant reduction of the amplitude of TEOAE test and significant increase in wave I and V latency and I-V inter-peak latency at both RR 21.2 and 51.2 msec when compared to the control group. A positive correlation was found in this study between the changes in ABR latency and the severity of verbal disability. These resuts leed to the conclusion that Auditory dysfunction in autistic children can be verified through the presence of cochlear involvement and a delay in the brain stem transmission time in those patients. Disturbed verbal communication can be due to dysfunction in the auditory processing mechanisms

  8. Porphyrinuria in childhood autistic disorder: Implications for environmental toxicity

    International Nuclear Information System (INIS)

    To address a possible environmental contribution to autism, we carried out a retrospective study on urinary porphyrin levels, a biomarker of environmental toxicity, in 269 children with neurodevelopmental and related disorders referred to a Paris clinic (2002-2004), including 106 with autistic disorder. Urinary porphyrin levels determined by high-performance liquid chromatography were compared between diagnostic groups including internal and external control groups. Coproporphyrin levels were elevated in children with autistic disorder relative to control groups. Elevation was maintained on normalization for age or to a control heme pathway metabolite (uroporphyrin) in the same samples. The elevation was significant (P < 0.001). Porphyrin levels were unchanged in Asperger's disorder, distinguishing it from autistic disorder. The atypical molecule precoproporphyrin, a specific indicator of heavy metal toxicity, was also elevated in autistic disorder (P < 0.001) but not significantly in Asperger's. A subgroup with autistic disorder was treated with oral dimercaptosuccinic acid (DMSA) with a view to heavy metal removal. Following DMSA there was a significant (P = 0.002) drop in urinary porphyrin excretion. These data implicate environmental toxicity in childhood autistic disorder

    Full Text Available Thematic focus: The motor abnormalities may be part of so-called comorbidities that can coexist with autistic disorder. Objective: To characterize the motor profile of students with autistic disorder. Method: the study included six children with autistic disorder in elementary school, male, aged 5 years and 5 months and 10 years and 9 months. After signing the consent form by parents or guardians, the students were submitted to the Motor Development Scale for assessment of fine motor, gross motor performance, balance, body scheme, spatial organization, temporal organization and laterality. Results: The results revealed a significant difference between the motor age and chronological age. According to the classification of the Scale of Motor Development, students in this study showed motor development lower than expected for age. Conclusion: The students with autistic disorder in this study presented a profile of Developmental Coordination Disorder in comorbidity, showing that participants of this research presented difficulties in activities that required skills such as handwriting. Thus, motor and psychomotor needs of these students were focused on educational and clinical environment to reduce the impact of behavioral and social manifestations.

    2011-01-01

    Pervasive Developmental Disorders (PPD) refers to the group of disorders characterised by delayed or inappropriate development of multiple basic functions including socialisation, communication, behaviour and cognitive functioning. The term,,autistic spectrum disorders" was established as a result of the magnitude of the intensity of symptoms and their proportions observed in all types of pervasive developmental disorders. Asperger's Syndrome (AS) remains the most controversial diagnosis in terms of its place within autism spectrum disorders. AS if often described as an equivalent of High Functioning Autism (HFA) or as a separate spectrum-related disorder with unique diagnostic criteria. Another important issue is the relationship between AS and speech disorders. Although it is relatively easy to draw a line between children with classical autism and speech disorders, the clear cut frontiers between them still remain to be found. The main distinguishing feature is the lack of stereotypic interests and unimpaired social interaction observed in children with speech disorders, such as semantic-pragmatic disorder. PMID:22220491

  18. Partial trisomy 16p in an adolescent with autistic disorder and Tourette`s syndrome

    1994-09-15

    A partial trisomy 16p was identified in a 14-year-old male adolescent with autistic disorder. He additionally showed complex motor and vocal phenomena, including some simple tics which had first appeared in childhood. Whereas these simple tics were of subclinical significance, an additional diagnosis of Tourette`s syndrome (TS) appears justified. The case report illustrates the diagnostic difficulties in assessing psychiatric symptomatology associated with both disorders, especially complex motor and vocal phenomena. The cytogenetic finding is discussed critically in the light of other chromosome abnormalities reported in both TS and autistic disorder. Chromosome 16p should be considered as a candidate region especially for autistic disorder. 21 refs.

    Prader-Willi syndrome (PWS) is a neuro-genetic disorder caused by the absence/loss of expression of one or more paternally expressed genes on chromosome 15 (q11-13). In this study, a comparative analysis of intelligence level and autistic traits was conducted between children with PWS (n = 30; 18 males, 12 females; age = 10.6 ± 2.8 years) and those with Asperger disorder (AD; n = 31; 24 males, 7 females; age = 10.5 ± 3.1 years). The children were compared by age group: lower elementary school age (6-8 years), upper elementary school age (9-12 years), and middle school age (13-15 years). As results, the intelligence levels of children with PWS were significantly lower than those with AD across all age groups. Autistic traits, assessed using the Pervasive Developmental Disorders Autism Society Japan Rating Scale (PARS), revealed that among elementary school age children, those with PWS had less prominent autistic traits than those with AD, however, among middle school age children, those with PWS and AD showed similar prominence. An analysis of the PARS subscale scores by age group showed that while the profiles of autistic traits for children with PWS differed from those of children with AD at elementary school age, the profiles showed no significant differences between the groups at middle school age. The findings suggest that autistic traits in PWS become gradually more prominent with increasing of age and that these autistic traits differ in their fundamental nature from those observed in AD.

    1995-06-01

    Infantile autism is a pervasive developmental disorder characterized by disturbances concerning not only the areas of socialization and communication ("aloneness") but also the ability to modify and change behavior ("need for sameness"). In most recent studies, various abnormal and deviant cognitive activities, such as the ability to regulate one's behavior, were considered as accounting for these signs. In this report, we examined the regulation of cognitive activity, from a developmental perspective in comparing autistic with mentally retarded children matched in a pairwise manner by global, verbal, and nonverbal developmental ages. All children were tested with tasks adapted from the Object Permanence Test which corresponds to Piaget's sensorimotor development Stages IV to VI. Results showed that autistic children had a pervasive difficulty in maintenance set, made more perseverative errors when the abstraction degree of task was higher, and were more variable in their behavioral strategies. Discussion is focused on the interests and limits of these tasks for the examination of regulation activity from diagnostic and developmental perspectives. Finally, interpretations about recent neuropsychological and neurophysiological works, and additional interdisciplinary studies are suggested. PMID:7559291

    Full Text Available Background. User feedback is now an integral part of both clinical governance and service development, and it also provides a key route to engaging parents and children. Autistic spectrum disorders (ASDs can impact on all members of a family, and close working between parents and professionals is essential. Aim. To explore parental satisfaction rates and identify areas in need of improvement. Method. A postal survey was completed by parents whose children had been diagnosed with an ASD in the past 18 months in a Manchester Child and Adolescent Mental Health Service. The National Autism Plan for Children was used as a gold standard. Results. Parents were particularly satisfied with the way team members dealt with them and their children during appointments. However, the standard of written information provided about the condition, diagnosis, and support available could be improved. The findings show the benefits of receiving a diagnosis in the recommended timeframe. Discussion. We discuss ways of effectively using scarce resources.

  9. Prevalence of Parasomnia in Autistic Children with Sleep Disorders

    Full Text Available The prevalence of sleep related complaints is reported by questionnaire studies to be as high as 83.3% in children with autism spectrum disorders (ASD. Questionnaire studies report the presence of various parasomnia in ASD. However, no polysomnographic study reports non-REM parasomnias and only a single study reports REM related parasomnias in ASD. We investigated the prevalence and characteristics of sleep disorders by polysomnographic study and questionnaires in a cohort of 23 children with ASD and 23 age-matched children of a non-autistic comparison group. The results showed significantly more non-REM parasomnias in 14 children with ASD on polysomnograms (PSG and 16 ASD children by questionnaire, a finding that was not associated with medication use, other comorbid medical or psychiatric disorders, or sleep disordered breathing. Of the 14 children with ASD who had PSG evidence of parasomnia, 11 of them had a history suggestive of parasomnia by questionnaire. There was a high sensitivity but a low specificity of parasomnia in ASD by questionnaire in predicting the presence of parasomnia in the PSG. Of the parasomnias recorded in the laboratory, 13 ASD children had Disorders of Partial Arousal, consistent with sleep terrors or confusional arousals. Furthermore, multiple episodes of partial arousal occurred in 11 of the 13 ASD children who had PSG evidence of Disorders of Partial Arousal. Of the 11 ASD children with multiple episodes of partial arousal, 6 ASD children had multiple partial arousals during both nights’ PSG study. Sleep architecture was abnormal in children with ASD, characterized by increased spontaneous arousals, prolonged REM latency and reduced REM percentage. These results suggest a high prevalence of parasomnia in this cohort of children with ASD and a careful history intake of symptoms compatible with parasomnia could be prudent to diagnose parasomnia in ASD children when performing a PSG is not possible.

    Junko Matsuo

    Full Text Available Autism spectrum disorder often co-occurs with other psychiatric disorders. Although a high prevalence of autistic-like traits/symptoms has been identified in the pediatric psychiatric population of normal intelligence, there are no reports from adult psychiatric population. This study examined whether there is a greater prevalence of autistic-like traits/symptoms in patients with adult-onset psychiatric disorders such as major depressive disorder (MDD, bipolar disorder, or schizophrenia, and whether such an association is independent of symptom severity. The subjects were 290 adults of normal intelligence between 25 and 59 years of age (MDD, n=125; bipolar disorder, n=56; schizophrenia, n=44; healthy controls, n=65. Autistic-like traits/symptoms were measured using the Social Responsiveness Scale for Adults. Symptom severity was measured using the Positive and Negative Symptoms Scale, the Hamilton Depression Rating Scale, and/or the Young Mania Rating Scale. Almost half of the clinical subjects, except those with remitted MDD, exhibited autistic-like traits/symptoms at levels typical for sub-threshold or threshold autism spectrum disorder. Furthermore, the proportion of psychiatric patients that demonstrated high autistic-like traits/symptoms was significantly greater than that of healthy controls, and not different between that of remitted or unremitted subjects with bipolar disorder or schizophrenia. On the other hand, remitted subjects with MDD did not differ from healthy controls with regard to the prevalence or degree of high autistic-like traits/symptoms. A substantial proportion of adults with bipolar disorder and schizophrenia showed high autistic-like traits/symptoms independent of symptom severity, suggesting a shared pathophysiology among autism spectrum disorder and these psychiatric disorders. Conversely, autistic-like traits among subjects with MDD were associated with the depressive symptom severity. These findings suggest the

    2010-12-01

    Successful word learning depends on the integration of phonological and semantic information with social cues provided by interlocutors. How then, do children with autism spectrum disorders (ASDs) learn new words when social impairments pervade? We recorded the eye-movements of verbally-able children with ASD and their typical peers while completing a word learning task in a social context. We assessed learning of semantic and phonological features immediately after learning and again four weeks later. Eye-movement data revealed that both groups could follow social cues, but that typically developing children were more sensitive to the social informativeness of gaze cues. In contrast, children with ASD were more successful than peers at mapping phonological forms to novel referents; however, this advantage was not maintained over time. Typical children showed clear consolidation of learning both semantic and phonological information, children with ASD did not. These results provide unique evidence of qualitative differences in word learning and consolidation and elucidate the different mechanisms underlying the unusual nature of autistic language.

  1. Aggression in low functioning children and adolescents with autistic disorder.

    Directory of Open Access Journals (Sweden)

    Guillaume Bronsard

    Full Text Available BACKGROUND: Parents, caregivers and mental health professionals have often reported violence and aggression in children or adolescents with autistic disorder. However, most of these observations derived from anecdotal reports, and studies on frequency and characterization of aggression in autism remain limited. Our objective was to better characterize and understand the different types of aggressive behaviors displayed by a large group of individuals with autism in different observational situations. METHODOLOGY/FINDINGS: The study was conducted on 74 children and adolescents with autism and 115 typically developing control individuals matched for sex, age and pubertal stage. Other-Injurious Behaviors (OIB were assessed in three observational situations (parents at home, two caregivers at day-care, a nurse and a child psychiatrist during blood drawing using validated scales. The frequency of OIB was significantly higher in individuals with autism compared to typically developing control individuals during the blood drawing (23% vs. 0%, P<0 .01. The parents observed significantly less OIB in their children than caregivers (34% vs. 58%, P<0.05. In addition, the most frequent concurrent behaviors occurring just before the appearance of OIB in individuals with autism were anxiety-related behaviors and excitation according to the parental as well as the caregiver observation. CONCLUSIONS/SIGNIFICANCE: The results suggest that in a stressful situation, such as the blood drawing, individuals with autism release their stress through behaviors such as OIB, whereas typically developing individuals regulate and express their stress through cognitive skills such as mental coping strategies, symbolization skills with representation and anticipation of the stressful situation, social interaction and verbal or non-verbal communication. The findings underline also the key role of the environment in assessing OIB and developing therapeutic perspectives, with an

    2012-08-01

    Full Text Available Abstract Background Patients with autism spectrum disorders (ASDs exhibit core autistic symptoms including social impairments from early childhood and mostly show secondary disabilities such as irritability and aggressive behavior based on core symptoms. However, there are still no radical treatments of social impairments in these patients. Oxytocin has been reported to play important roles in multiple social behaviors dependent on social recognition, and has been expected as one of the effective treatments of social impairments of patients with ASDs. Case presentation We present a case of a 16-year-old girl with autistic disorder who treated by long-term administration of oxytocin nasal spray. Her autistic symptoms were successfully treated by two month administration; the girl’s social interactions and social communication began to improve without adverse effects. Her irritability and aggressive behavior also improved dramatically with marked decreases in aberrant behavior checklist scores from 69 to 7. Conclusion This case is the first to illustrate long-term administration of oxytocin nasal spray in the targeted treatment of social impairments in a female with autistic disorder. This case suggests that long-term nasal oxytocin spray is promising and well-tolerated for treatment of social impairments of patients with ASDs.

  18. ON DIFFERENTIAL DIAGNOSIS BETWEEN AUTISTIC DISORDER AND ASPERGER’S SYNDROME

    Directory of Open Access Journals (Sweden)

    Stefan Todorov

    2012-11-01

    Full Text Available The differential diagnosis between Autistic disorder (AD and Asperger’s syndrome (AS in most cases is quite difficult since most of the symptoms are clinically undistinguished. Several factors complicate the diagnosis of AS- an autism spectrum disorder (ASD. It is considered by some authors to be simply a milder version of autistic disorder. Problems in diagnosis include disagreement among diagnostic criteria, controversy over the distinction between AS and other ASD forms or even whether AS exists as a separate syndrome, and over- and under-diagnosis. Our paper is based on the diagnostic and differential diagnostic criteria of DSM-IV, ICD-10 and our clinical experience.In the process of diagnosis and differential diagnosis we, naturally, illustrate and discuss the similarities and differences between the two disorders.

    Full Text Available Autism is one of the five disorders that falls under the umbrella of Pervasive Developmental Disorders (PDD or Autism Spectrum Disorder (ASD, a category of neurological disorders characterized by "severe and pervasive impairment in several areas of development." ASD is characterized by varying degrees of impairment in communication skills, social interaction and restricted, repetitive stereotyped patterns of behavior. The five disorders under PDD are autistic disorder, Asperger′s disorder, childhood disintegrative disorder, Rett′s disorder and PDD-not otherwise specified. ASD can often be reliably detected by the age of 3 years and, in some cases, as early as 18 months. The appearance of any warning signs of ASD is reason to have the child evaluated by a professional specializing in these disorders.

  6. Autism and autistic spectrum disorders in the context of new DSM-V classification, and clinical and epidemiological data

    Directory of Open Access Journals (Sweden)

    Stanković Miodrag

    2012-01-01

    Full Text Available Autism is one of disorders from the autism spectrum, besides Asperger syndrome, atypical autism and pervasive developmental disorder not otherwise specified. They are classified as mental disorders as being manifested by a wide range of cognitive, emotional and neurobehavioural abnormalities. Key categorical characteristics of the disorder are clear impairments of the development of the child’s socialisation, understanding and production of verbal and non-verbal communication and restricted and repetitive patterns of behaviour. Demarcation boundaries are not clear, neither within the very group of the disorders from the autistic spectrum, nor with respect to the autistic behavioural features in the general population. For this reason, the term spectrum points out the significance of the dimensional assessment of autistic disorders, which will most likely be the basis of the new diagnostic classification of the disorders belonging to the current group of pervasive developmental disorders in the new DSM-V classification. The understanding, as well as the prevalence of the autistic spectrum disorders has changed drastically in the last four decades. From the previous 4 per 10,000 people, today’s prevalence estimates range from 0.6 to around 1%, and the increase of prevalence cannot be explained solely by better recognition on the part of experts and parents or by wider diagnostic criteria. The general conclusion is that the autistic spectrum disorders are no longer rare conditions and that the approach aimed at acknowledging the warning that this is an urgent public health problem is completely justified.

    Full Text Available Purpose. Immune system of some autistic patients could be abnormally triggered by gluten/casein assumption. The prevalence of antibodies to gliadin and milk proteins in autistic children with paired/impaired intestinal permeability and under dietary regimen either regular or restricted is reported. Methods. 162 ASDs and 44 healthy children were investigated for intestinal permeability, tissue-transglutaminase (tTG, anti-endomysium antibodies (EMA-IgA, and total mucosal IgA to exclude celiac disease; HLA-DQ2/-DQ8 haplotypes; total systemic antibodies (IgA, IgG, and IgE; specific systemic antibodies: α-gliadin (AGA-IgA and IgG, deamidated–gliadin-peptide (DGP-IgA and IgG, total specific gliadin IgG (all fractions: α, β, γ, and ω, β-lactoglobulin IgG, α-lactalbumin IgG, casein IgG; and milk IgE, casein IgE, gluten IgE, -lactoglobulin IgE, and α-lactalbumin IgE. Results. AGA-IgG and DPG-IgG titers resulted to be higher in ASDs compared to controls and are only partially influenced by diet regimen. Casein IgG titers resulted to be more frequently and significantly higher in ASDs than in controls. Intestinal permeability was increased in 25.6% of ASDs compared to 2.3% of healthy children. Systemic antibodies production was not influenced by paired/impaired intestinal permeability. Conclusions. Immune system of a subgroup of ASDs is triggered by gluten and casein; this could be related either to AGA, DPG, and Casein IgG elevated production or to impaired intestinal barrier function.

    Full Text Available There is now a strong if not urgent call in both the attachment and autism literatures for updated, research informed, clinically relevant interventions that can more effectively assess the mother infant dyad during early periods of brain plasticity. In this contribution I describe my work in regulation theory, an overarching interpersonal neurobiological model of the development, psychopathogenesis, and treatment of the early forming subjective self system. The theory models the psychoneurobiological mechanisms by which early rapid, spontaneous and thereby implicit emotionally-laden attachment communications indelibly impact the experience-dependent maturation of the right brain, the “emotional brain.” Reciprocal right-lateralized visual-facial, auditory-prosodic, and tactile-gestural nonverbal communications lie at the psychobiological core of the emotional attachment bond between the infant and primary caregiver. These affective communications can in turn be interactively regulated by the primary caregiver, thereby expanding the infant’s developing right brain regulatory systems. Regulated and dysregulated bodily-based communications can be assessed in order to determine the ongoing status of both the infant’s emotional and social development as well as the quality and efficiency of the infant-mother attachment relationship. I then apply the model to the assessment of early stages of autism. Developmental neurobiological research documents significant alterations of the early developing right brain in autistic infants and toddlers, as well profound attachment failures and intersubjective deficits in autistic infant-mother dyads. Throughout I offer implication of the theory for clinical assessment models. This work suggests that recent knowledge of the social and emotional functions of the early developing right brain may not only bridge the attachment and autism worlds, but facilitate more effective attachment and autism models of

    Autism spectrum disorder (ASD) and Alzheimer's disease (AD) are neurodevelopmental and neurodegenerative disorders respectively, with devastating effects not only on the individual but also the society. Collectively, a number of factors contribute to the expression of ASD and AD. It is of utmost curiosity that these disorders express at different stages of life and there is an involvement of certain susceptible genes. This genetic basis makes the background of common associations like memory deficits, cognition changes, demyelination, oxidative stress and inflammation, an integral part of both disorders. Modern technology resulting in genetically modified crops and increase in gadgets emitting electromagnetic frequencies have resulted in enhanced risks for neurological dysfunctions and disorders like ASD and AD. Subsequent advances in the psychological, pharmacological, biochemical and nutritional aspects of the disorders have resulted in the development of newer therapeutic approaches. The common clinical features like language impairment, executive functions, and motor problems have been discussed along with the patho-physiological changes, role of DNA methylation, myelin development, and heavy metals in the expression of these disorders. Psychopharmacological and nutritional approaches towards the reduction and management of risk factors have gained attention from the researchers in recent years. Current major therapies either target the inflammatory pathways or reduce cellular oxidative stress. This contribution focuses on the commonalities of the two disorders. PMID:26996178

    Full Text Available Autism is a neural development disorder characterized by the deterioration in social interacttion, abnormal language expression, repetitive actions, imaginative game tendencies, and limited and/or obsessiveness in certain activities/ interests. Lack of sleep is one of the factors contributing to the worsening of overall negative symptoms of autistic children. From the Islamic perspective, sleep is a necessity and could function as a treatment for health problems, in addition to influencing behavior patterns. Sound therapy has been used in dealing with various health problems, including sleep problems and mental ill health. Possibly, it can also address sleep problems of the autistic children. Listening to the melodious Qur’anic recitation is known to have therapeutic effects even on individuals who do not understand the meaning of the verses being read; it could function as sound therapy. However, no established work has been done to study the effect of Qur’anic verses recitation on autistic children and their sleep problems. Similar to the use of music therapy, Qur’anic recitation is also expected to have a positive impact on speech, learning and interpersonal relationship. As a healing medium, Qur’anic therapy is also expected to have a better result as compared to other conventional sound therapy since its content could be psychotherapeutic.

  20. Parental and grandparental ages in the autistic spectrum disorders: a birth cohort study.

    Full Text Available BACKGROUND: A number of studies have assessed ages of parents of children with autistic spectrum disorders (ASD, and reported both maternal and paternal age effects. Here we assess relationships with grandparental ages. METHODS AND FINDINGS: We compared the parental and grandparental ages of children in the population-based Avon Longitudinal Study of Parents and Children (ALSPAC, according to their scores in regard to 4 autistic trait measures and whether they had been given a diagnosis of ASD. Mean maternal and paternal ages of ASD cases were raised, but this appears to be secondary to a maternal grandmother age effect (P = 0.006: OR = 1.66[95%CI 1.16, 2.37] for each 10-year increase in the grandmother's age at the birth of the mother. Trait measures also revealed an association between the maternal grandmother's age and the major autistic trait-the Coherence Scale (regression coefficient b = 0.142, [95%CI = 0.057, 0.228]P = 0.001. After allowing for confounders the effect size increased to b = 0.217[95%CI 0.125, 0.308](P<0.001 for each 10 year increase in age. CONCLUSIONS: Although the relationship between maternal grandmother's age and ASD and a major autistic trait was unexpected, there is some biological plausibility, for the maternal side at least, given that the timing of female meiosis I permits direct effects on the grandchild's genome during the grandmother's pregnancy. An alternative explanation is the meiotic mismatch methylation (3 M hypothesis, presented here for the first time. Nevertheless the findings should be treated as hypothesis generating pending corroborative results from other studies.

    Full Text Available Abstract Autism spectrum disorders (ASD are a group of pervasive neurodevelopmental disorders diagnosed in early childhood. They are associated with a set of "core symptoms" that include disabilities in social interaction skills, verbal and non-verbal communication, as well as repetitive and stereotypic behaviors. There is no definite pathogenetic mechanism or diagnostic tests. Many children with ASD also have "allergic-like" symptoms, but test negative implying mast cell activation by non-allergic triggers. We measured by Milliplex arrays serum levels of 3 neuropeptides that could stimulate mast cells in children with autistic disorder (n = 19; 16 males and 3 females; mean age 3.0 ± 0.4 years and healthy, unrelated controls (n = 16; 13 males and 3 females; mean age 3 ± 1.2 years. Only neurotensin (NT was significantly increased from 60.5 ± 6.0 pg/ml in controls to 105.6 ± 12.4 pg/ml in autistic disorder (p = 0.004. There was no statistically significant difference in the serum levels of β-endorphin or substance P (SP. NT could stimulate immune cells, especially mast cells, and/or have direct effects on brain inflammation and ASD.

    Dardas, Latefa A; Ahmad, Muayyad M

    2015-02-01

    The purpose of this cross-sectional study was to examine coping strategies as mediators and moderators between stress and quality of life (QoL) among parents of children with autistic disorder. The convenience sample of the study consisted of 184 parents of children with autistic disorder. Advanced statistical methods for analyses of mediator and moderator effects of coping strategies were used. The results revealed that 'accepting responsibility' was the only mediator strategy in the relationship between stress and QoL. The results also revealed that only 'seeking social support' and 'escape avoidance' were moderator strategies in the relationship between stress and QoL. This study is perhaps the first to investigate the mediating and moderating effects of coping on QoL of parents of children with autistic disorder. Recommendations for practice and future research are presented. PMID:23868562

    There is a co-morbidity between autism spectrum behaviour disorders and deafness in children. Their behavioural difficulties may appear primary and/or secondary to hearing deprivation. In this paper, we present how we manage those patients on the base of our clinical experience. The auditory assessment must be based on subjective tests taking account of their special reactions. It needs objective tests to complete and help the behavioural responses. The hearing aids amplification is increased progressively, to allow the development of a tolerance to the sounds world. The multidisciplinary team tends to open them to the world and to the communication. PMID:16676561

    2016-08-01

    The present web-based study (N = 840) aimed to illuminate the cognitive mechanisms underlying self-disorders in autism. Initially, participants selected three self-defining memories. Then, we assessed their capacity to give meaning to these events (i.e., meaning making), their tendency to scrutinize autobiographical memory to better understand themselves (i.e., self-continuity function of autobiographical memory) and their clarity of self-concept. The results showed that individuals with high autistic traits (ATs) had a lower clarity of self-concept than control participants. Meaning making was also reduced in AT individuals and mediated the relation between AT and self-concept clarity. Our results suggest that the reduced clarity of self-concept in AT individuals is related to an impaired capacity to make meaning of important past life events. PMID:27101235

    In this report we aim to explore severe deficits in facial affect recognition in three boys all of whom meet the criteria of Asperger's syndrome (AS), as well as overt prosopagnosia in one (B) and covert prosopagnosia in the remaining two (C and D). Subject B, with a familially-based talent of being highly gifted in physics and mathematics, showed no interest in people, a quasi complete lack of comprehension of emotions, and very poor emotional reactivity. The marked neuropsychological deficits were a moderate prosopagnosia and severely disordered recognition of facial emotions, gender and age. Expressive facial emotion, whole body psychomotor expression and speech prosody were quasi absent as well. In all three boys these facial processing deficits were more or less isolated, and general visuospatial functions, attention, formal language and scholastic performances were normal or even highly developed with the exception of deficient gestalt perception in B. We consider the deficient facial emotion perception as an important pathogenetic symptom for the autistic behaviour in the three boys. Prosopagnosia, the absent facial and bodily expression, and speech prosody were important but varying co-morbid disorders. The total clinical picture of non-verbal disordered communication is a complex of predominantly bilateral and/or right hemisphere cortical deficits. Moreover, in B, insensitivity to pain, smells, noises and internal bodily feelings suggested a more general emotional anaesthesia and/or a deficient means of expression. It is possible that a limbic component might be involved, thus making affective appreciation also deficient. PMID:11315539

    2014-08-01

    Full Text Available This study analyzes the technologies most widely used to work on areas affected by the Autistic Spectrum Disorder (ASD. Technologies can focus on the strengths and weaknesses of this disorder as they make it possible to create controlled environments, reducing the anxiety produced by real social situations. Extensive research has proven the efficiency of technologies as support tools for therapy and their acceptation by ASD sufferers and the people who are with them on a daily basis. This article is organized by the types of systems developed: virtual reality applications, telehealth systems, social robots and dedicated applications, all of which are classified by the areas they center on: communication, social learning and imitation skills and other ASD-associated conditions. 40.5% of the research conducted is found to be focused on communication as opposed to 37.8% focused on learning and social imitation skills and 21.6% which underlines problems associated with this disorder. Although most of the studies reveal how useful these tools are in therapy, they are generic tools for ASD sufferers in general, which means there is a lack of personalised tools to meet each person’s needs.

  5. Investigating mechanisms underlying neurodevelopmental phenotypes of autistic and intellectual disability disorders: a perspective

    Directory of Open Access Journals (Sweden)

    Tim eKroon

    2013-10-01

    Full Text Available Brain function and behaviour undergo significant plasticity and refinement, particularly during specific critical and sensitive periods. In autistic and intellectual disability neurodevelopmental disorders (NDDs and their corresponding genetic mouse models, impairments in many neuronal and behavioural phenotypes are temporally regulated and in some cases, transient. However, the links between neurobiological mechanisms governing typically normal brain and behavioural development (referred to also as ‘neurotypical’ development and timing of NDD impairments are not fully investigated.This perspective highlights temporal patterns of synaptic and neuronal impairment, with a restricted focus on autism and intellectual disability types of NDDs. Given the varying known genetic and environmental causes for NDDs, this perspective proposes two strategies for investigation: (1 a focus on neurobiological mechanisms underlying known critical periods in the (typically normal-developing brain (2 investigation of spatio-temporal expression profiles of genes implicated in monogenic syndromes throughout affected brain regions.This approach may help explain why many NDDs with differing genetic causes can result in overlapping phenotypes at similar developmental stages and better predict vulnerable periods within these disorders, with implications for both therapeutic rescue and ultimately, prevention.

    Full Text Available Background: The aim of the present study was to evaluate the effect of risperidone in patients afflicted by autistic disorder especially with regards to its three core symptoms, including "relating to others", "communication skills", and "stereotyped behaviors" based on Childhood Autism Rating Scale (CARS. Materials and Methods: An 8-week open-label study of risperidone for treatment of autistic disorder in children 4-17 years old was designed. Risperidone dose titration was as follow: 0.02 mg/kg/day at the first week, 0.04 mg/kg/day at the second week, and 0.06 mg/kg/day at the third week and thereafter. The outcome measures were scores obtained by CARS, Aberrant Behavior Checklist (ABC, and Clinical Global Impression-Improvement (CGI-I scale. Results: Fifteen patients completed this study. After 8 weeks, CARS total score decreased significantly, (P=0.001. At the end of the study, social interactions and verbal communication skills of the patients were significantly improved (P<0.001, P=0.03, respectively. However, stereotypic behaviors did not show any significant change in this study. Increase in appetite and somnolence were the most reported side effects. Conclusion: This study suggests that risperidone may be an effective treatment for the management of core symptoms of autistic disorder.

    2014-10-01

    Children with autistic spectrum disorder (ASD) are reported to have difficulties with narrative language but little is known about how this affects their production of fictional stories. In this study, we aimed to establish whether fictional narratives of children with ASD differed from those of typically developing children and if performance was commensurate with levels of oral language. Fictional stories produced by 27 high functioning children with ASD, aged 11-14 yrs, were compared with those of language and age matched groups of typically developing children. Differences were found between the children with ASD and comparison groups in structural, evaluative and global features of their stories indicating specific difficulties with this form of narrative. Stories of the ASD group were shorter and contained fewer causal statements than those of both comparison groups and sentences were less grammatically complex than those of the age match but not the language match group. In global measures, the stories of the ASD group were impoverished relative to both comparison groups. The results are discussed in relation to cognitive theories of autism and language development.

  9. Hypnosis Without Empathy? Perspectives From Autistic Spectrum Disorder and Stage Hypnosis.

    Reid, David B

    2016-01-01

    Despite volumes of published studies supporting the efficacy of hypnosis for ego-strengthening, performance, and physical and psychological disorders, the precise nature of hypnosis, and in particular, the neurobiological underpinnings of trance-phenomenon, remains tenuous at best. With his empathic involvement theory of hypnosis, Wickramasekera II (2015) brings us closer to an understanding of the elusive nature of hypnotic processes by proposing a bridging of two long-standing and seemingly incongruent theories of hypnosis (i.e., neodissociative versus socio-cognitive). Borrowing from neuroscientific studies of empathy, the empathic involvement theory maintains that empathy, beyond any other human dynamic (including emotions, behavior, personality, and imagination), facilitates and enhances hypnotic experiences for both recipient and provider alike. By the same token, one can reasonably infer from the empathic involvement theory that non-empathic individuals are less likely to benefit from hypnosis. With this perspective in mind, the empathic involvement theory's identification of empathy as an apparent "Holy Grail" of the neural underpinnings and precise nature of hypnosis may be challenged on a number of grounds. Individuals with autistic spectrum disorder, especially those suffering from alexithymia, have been identified as empathy deficient, and therefore according to the empathic involvement theory would be classified as "low-hypnotizable," yet empirical studies, albeit limited in number, suggest otherwise. Furthermore, hypnotic inductions of audience volunteers by stage hypnotists challenge the empathic involvement theory's supposition that empathy is a required component of hypnosis. It is this author's contention that empathy is a beneficial, though not essential, element of successful hypnosis. PMID:26675158

    2002-01-01

    Autism is an early developmental disorder. It leads to severe and durable disturbances. Given this problem, no treatment can be excluded a priori. Thus, many approaches are used to deal with autistic disorders. In France, pharmacological treatments are, for instance, largely and mostly used in adults. In the USA, these treatments concern 50% of persons with autism of any age. Nevertheless, they are rarely based on controlled studies. At the present, however, prescriptions and expected effects appear to be hard to localize. Furthermore, only few controlled studies validate their use. Aim - We offer a review of studies about medical treatments used in adolescents and adults with autism. They are classified in 3 categories: the first (category I) includes drugs used for their neurochemical effects focusing on autistic signs. The second (category II) covers drugs used for treatment of behavioural disorders frequently associated with autism. The third (category III) corresponds to a wide range of drugs or vitamins for wich only few case studies exist reporting irregular positive effects. The main hypothesis of this review is that autism involves a dysfunction of the neuromediation systems. This hypothesis opens new perspectives in the research of medical treatments in autism by focusing on molecules, which are supposed to have an effect on neuromediation systems. Method - Our review is based on studies, which have been published during the past twenty years. For many studies, data are limited to adolescents and adults. So we expanded our review to data available in children. The data bases that we have used are medline and psyclit. Keywords have been chosen according to: pharmacological considerations (psychotropic, psychoactive drugs, psychopharmacology) and clinical symptoms (autism, automutilations, aggressive behavior, and hyperactivity). Hypothesis of a dysfunction in the neuromediation systems in autism - Many studies exist about biochemical abnormalities in

    2015-09-01

    To evaluate the routine usage of Magnetic Resonance Imaging (MRI) of brain and estimate the prevalence of brain abnormalities in children presenting to the Neurodevelopment Clinic of Al-Khadra Hospital (NDC-KH), Tripoli, Libya with autistic spectrum disorders (ASD). The records of all children with ASD presented to NDC-KH over 4-year period (from January 2009 to December 2012) were reviewed. All MRIs were acquired with a 1.5-T Philips (3-D T1, T2, FLAIR coronal and axial sequences). MRIs were reported to be normal, abnormal or no significant abnormalities by a consultant neuroradiologist. One thousand and seventy-five children were included in the study. Seven hundred and eighty-two children (72.7 %) had an MRI brain of whom 555 (71 %) were boys. 26 children (24 males and 2 females) (3.3 %) demonstrated MRI abnormalities (8 leukodystrophic changes, 4 periventricular leukomalacia, 3 brain atrophy, 2 tuberous sclerosis, 2 vascular changes, 1 pineoblastoma, 1 cerebellar angioma, 1 cerebellar hypoplasia, 3 agenesis of corpus callosum, 1 neuro-epithelial cyst). An unexpectedly high rate of MRI abnormalities was found in the first large series of clinical MRI investigations in children with autism. These results could contribute to further research into the pathogenesis of autistic spectrum disorder. PMID:25344829

  4. Reduced object related negativity response indicates impaired auditory scene analysis in adults with autistic spectrum disorder

    Directory of Open Access Journals (Sweden)

    Veema Lodhia

    2014-02-01

    Full Text Available Auditory Scene Analysis provides a useful framework for understanding atypical auditory perception in autism. Specifically, a failure to segregate the incoming acoustic energy into distinct auditory objects might explain the aversive reaction autistic individuals have to certain auditory stimuli or environments. Previous research with non-autistic participants has demonstrated the presence of an Object Related Negativity (ORN in the auditory event related potential that indexes pre-attentive processes associated with auditory scene analysis. Also evident is a later P400 component that is attention dependent and thought to be related to decision-making about auditory objects. We sought to determine whether there are differences between individuals with and without autism in the levels of processing indexed by these components. Electroencephalography (EEG was used to measure brain responses from a group of 16 autistic adults, and 16 age- and verbal-IQ-matched typically-developing adults. Auditory responses were elicited using lateralized dichotic pitch stimuli in which inter-aural timing differences create the illusory perception of a pitch that is spatially separated from a carrier noise stimulus. As in previous studies, control participants produced an ORN in response to the pitch stimuli. However, this component was significantly reduced in the participants with autism. In contrast, processing differences were not observed between the groups at the attention-dependent level (P400. These findings suggest that autistic individuals have difficulty segregating auditory stimuli into distinct auditory objects, and that this difficulty arises at an early pre-attentive level of processing.

    2008-03-01

    The relationship between emotional dream content and Alpha and Beta REM sleep EEG activity was investigated in typical individuals and in Autistic Spectrum Disorders (ASD). Dream narratives of persons with ASD contained fewer emotional elements. In both groups, emotions correlated positively with slow Alpha (8.0-10.0 Hz) spectral power over parieto-occipital and left central regions, as well as with a right occipital EEG asymmetry. Slow Alpha activity in ASD individuals was lower over midline and parasagittal areas and higher over lateral areas compared to controls. Both groups displayed a right-biased slow Alpha activity for midparietal and occipital (significantly higher in control) sites. Results indicate that Alpha EEG activity may represent a neurophysiological substrate associated with emotional dream content. Distinctive Alpha EEG patterns and asymmetries suggest that dream generation implies different brain connectivity in ASD. PMID:18047484

    Richardson, A J; Ross, M A

    2000-01-01

    There is increasing evidence that abnormalities of fatty acid and membrane phospholipid metabolism play a part in a wide range of neurodevelopmental and psychiatric disorders. This proposal is discussed here in relation to attention-deficit/hyperactivity disorder (ADHD), dyslexia, developmental coordination disorder (dyspraxia) and the autistic spectrum. These are among the most common neurodevelopmental disorders of childhood, with significant implications for society as well as for those directly affected. However, controversy still surrounds both the identification and management of these conditions, and while their aetiology is recognized as being complex and multifactorial, little progress has yet been made in elucidating predisposing factors at the biological level. An overview is provided here of the contents of this Special Issue, which contains a selection of reports from a unique multidisciplinary workshop involving both researchers and clinicians. Its purpose was to explore the possibility that ADHD, dyslexia, dyspraxia and autism fall within a phospholipid spectrum of disorders. This proposal could explain the high degree of co-morbidity between these conditions, their aggregation within families and relation to other psychiatric disorders, and a range of associated features that are already well known at a clinical level. The existing evidence for fatty acid abnormalities in these disorders is summarized, and new approaches are outlined that have the potential to improve both the identification and the management of these and related neurodevelopmental and psychiatric conditions.

    2015-10-01

    In the DSM-5, 'Asperger's Disorder' was incorporated into 'Autistic Spectrum Disorder' (ASD). One key concern in this change has been that the ASD label will increase negative attitudes relative to the Asperger's label. To test this, we asked 465 American adults to read a vignette describing a child with autistic symptoms that included an ASD label, an Asperger's label, or no label, and rate their stigma and treatment attitudes (help-seeking and perceived effectiveness). Contrary to predictions, label did not impact stigma. Label did impact treatment attitudes, with greater help-seeking and perceived treatment effectiveness for both Asperger's and ASD labels. In sum, concern that the ASD label will increase negative perceptions, at least amongst the general public, is not supported. PMID:26043847

    2014-03-01

    The Autism Detection in Early Childhood (ADEC; Young, 2007) was developed as a Level 2 clinician-administered autistic disorder (AD) screening tool that was time-efficient, suitable for children under 3 years, easy to administer, and suitable for persons with minimal training and experience with AD. A best estimate clinical Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association, 2000) diagnosis of AD was made for 70 children using all available information and assessment results, except for the ADEC data. A screening study compared these children on the ADEC with 57 children with other developmental disorders and 64 typically developing children. Results indicated high internal consistency (α = .91). Interrater reliability and test-retest reliability of the ADEC were also adequate. ADEC scores reliably discriminated different diagnostic groups after controlling for nonverbal IQ and Vineland Adaptive Behavior Composite scores. Construct validity (using exploratory factor analysis) and concurrent validity using performance on the Autism Diagnostic Observation Schedule (Lord et al., 2000), the Autism Diagnostic Interview-Revised (Le Couteur, Lord, & Rutter, 2003), and DSM-IV-TR criteria were also demonstrated. Signal detection analysis identified the optimal ADEC cutoff score, with the ADEC identifying all children who had an AD (N = 70, sensitivity = 1.0) but overincluding children with other disabilities (N = 13, specificity ranging from .74 to .90). Together, the reliability and validity data indicate that the ADEC has potential to be established as a suitable and efficient screening tool for infants with AD. PMID:24490680

    This study examined the relationship between child language skills and parent and child gestures of 58 youths with and without an autism spectrum disorder (ASD) diagnosis. Frequencies and rates of total gesture use as well as five categories of gestures (deictic, conventional, beat, iconic, and metaphoric) were reliably coded during the collaborative Tower of Hanoi task. Children with ASD had lower Peabody Picture Vocabulary Test scores and gestured less and at lower rates compared to typically developing children. Gesture use was unrelated to vocabulary for typically developing children, but positively associated with vocabulary for those with ASD. Demographic correlates of gesturing differed by group. Gesture may be a point of communication intervention for families with children with ASD. PMID:24535577

  8. Reducing auditory hypersensitivities in autistic spectrum disorders: Preliminary findings evaluating the Listening Project Protocol

    Directory of Open Access Journals (Sweden)

    Stephen W Porges

    2014-08-01

    Full Text Available Auditory hypersensitivities are a common feature of autism spectrum disorder (ASD. In the present study the effectiveness of a novel intervention, the Listening Project Protocol (LPP was evaluated in two trials conducted with children diagnosed with ASD. LPP was developed to reduce auditory hypersensitivities. LPP is based on a theoretical neural exercise model that uses computer altered acoustic stimulation to recruit the neural regulation of middle ear muscles. Features of the intervention stimuli were informed by basic research in speech and hearing sciences that has identified the specific acoustic frequencies necessary to understand speech, which must pass through middle ear structures before being processed by other components of the auditory system. LPP was hypothesized to reduce auditory hypersensitivities by increasing the neural tone to the middle ear muscles to functionally dampen competing sounds in frequencies lower than human speech. The trials demonstrated that LPP, when contrasted to control conditions, selectively reduced auditory hypersensitivities. These findings are consistent with the Polyvagal Theory, which emphasizes the role of the middle ear muscles in social communication.

    Full Text Available Background: Hyperlexia is a super ability demonstrated by a very specific group of individuals with developmental disorders. This term is used to describe the children with high ability in word recognition, but low reading comprehension skills, despite the problems in language, cognitive and social skills. The purpose of this study was to assess the effectiveness of improving the semantic aspect of language (increase in understanding and expression vocabulary on reading comprehension in an autistic child with hyperlexia.Case: The child studied in this research was an autistic child with hyperlexia. At the beginning of this study he was 3 years and 11 months old. He could read, but his reading comprehension was low. In a period of 12 therapy session, understanding and expression of 160 words was taught to child. During this period, the written form of words was eliminated. After these sessions, the reading comprehension was re-assessed for the words that child could understand and express.Conclusion: Improving semantic aspect of language (understanding and expression of vocabulary increase reading comprehension of written words.

    Full Text Available O transtorno autista e o grupo de condições relacionadas definidas como transtornos invasivos do desenvolvimento são transtornos de neurodesenvolvimento crônicos que começam na infância precoce e afetam um número significativo de crianças e suas famílias. Ainda que as causas e muito da fisiopatologia do transtorno sejam desconhecidas, em anos recentes, vários tratamentos medicamentosos disponíveis têm sido identificados como contendo a promessa de aliviar alguns dos comportamentos mal-adaptativos mais comprometedores associados aos transtornos invasivos do desenvolvimento. No entanto, esses tratamentos não enfocam os sintomas nucleares da enfermidade e, geralmente, seus efeitos colaterais excedem os benefícios. Portanto, há uma necessidade substancial de novas medicações que sejam mais seguras e mais eficazes em tratar os sintomas comportamentais do autismo. O objetivo desta revisão é o de destacar as farmacoterapias correntes disponíveis e aquelas emergentes e que tenham potencial de melhorar as opções de tratamento de pacientes com transtornos invasivos do desenvolvimento.Autistic disorder and the group of related conditions defined as pervasive developmental disorders are chronic neurodevelopmental disorders starting in early childhood and affecting a significant number of children and families.

    In recent years, the advent of comparative genomic hybridization (CGH) and single nucleotide polymorphism (SNP) arrays and its use as a first genetic test for the diagnosis of patients with neurodevelopmental phenotypes has allowed the identification of novel submicroscopic chromosomal abnormalities (namely, copy number variants or CNVs), imperceptible by conventional cytogenetic techniques. The 3q13.31 microdeletion syndrome (OMIM #615433) has been defined as a genomic disorder mainly characterized by developmental delay, postnatal overgrowth, hypotonia, genital abnormalities in males, and characteristic craniofacial features. Although the 3q13.31 CNVs are variable in size, a 3.4 Mb recurrently altered region at 3q13.2-q13.31 has been recently described and non-allelic homologous recombination (NAHR) mediated by flanking human endogenous retrovirus (HERV-H) elements has been suggested as the mechanism of deletion formation. We expand the phenotypic spectrum associated with this recurrent deletion performing the clinical description of a 9-year-old female patient with autistic disorder, total absence of language, intellectual disability, anxiety disorder and disruptive, and compulsive eating behaviors. The array-based molecular karyotyping allowed the identification of a de novo recurrent 3q13.2-q13.31 deletion encompassing 25 genes. In addition, we compare her clinical phenotype with previous reports of patients with neurodevelopmental and behavioral disorders and proximal 3q microdeletions. Finally, we also review the candidate genes proposed so far for these phenotypes. PMID:26332054

    2016-05-01

    Wechsler Intelligence Scale for Children (WISC) is widely used to estimate autistic intelligence (Joseph in The neuropsychology of autism. Oxford University Press, Oxford, 2011; Goldstein et al. in Assessment of autism spectrum disorders. Guilford Press, New York, 2008; Mottron in J Autism Dev Disord 34(1):19-27, 2004). However, previous studies suggest that while WISC-III and Raven's Progressive Matrices (RPM) provide similar estimates of non-autistic intelligence, autistic children perform significantly better on RPM (Dawson et al. in Psychol Sci 18(8):657-662, doi: 10.1111/j.1467-9280.2007.01954.x , 2007). The latest WISC version introduces substantial changes in subtests and index scores; thus, we asked whether WISC-IV still underestimates autistic intelligence. Twenty-five autistic and 22 typical children completed WISC-IV and RPM. Autistic children's RPM scores were significantly higher than their WISC-IV FSIQ, but there was no significant difference in typical children. Further, autistic children showed a distinctively uneven WISC-IV index profile, with a "peak" in the new Perceptual Reasoning Index. In spite of major changes, WISC-IV FSIQ continues to underestimate autistic intelligence. PMID:25308198

    2011-10-01

    Full Text Available Pervasive Developmental Disorders (PPD refers to the group of disorders characterised by delayed or inappropriate development of multiple basic functions including socialisation, communication, behaviour and cognitive functioning. The term „autistic spectrum disorders” was established as a result of the magnitude of the intensity of symptoms and their proportions observed in all types of pervasive developmental disorders. Asperger’s Syndrome (AS remains the most controversial diagnosis in terms of its place within autism spectrum disorders. AS if often described as an equivalent of High Functioning Autism (HFA or as a separate spectrum-related disorder with unique diagnostic criteria. Another important issue is the relationship between AS and speech disorders. Although it is relatively easy to draw a line between children with classical autism and speech disorders, the clear cut frontiers between them still remain to be found. The main distinguishing feature is the lack of stereotypic interests and unimpaired social interaction observed in children with speech disorders, such as semantic-pragmatic disorder.

    Few studies have compared the efficacy of the Picture Exchange Communication System (PECS) and iPads used as speech generating devices (SGDs), and none have targeted preschoolers. This study compares the relative efficacy of PECS and an iPad/SGD with three preschool-aged children with autism spectrum disorder and limited functional speech who lived in Malta. The study utilized an adapted alternating treatment design embedded in a multiple baseline design, with requesting of reinforcers as the dependent variable. Visual analysis of the results indicated that all participants required more prompted trials and sessions for the iPad/SGD condition. All participants learned a three step navigational sequence on the iPad. Participant preference probes were inconclusive and were not linked to speed of acquisition of requesting skills. Results suggest that both PECS and an iPad could be appropriate for teaching requesting skills to beginning communicators. PMID:26586580

    Full Text Available Introduction Emerging hypotheses suggest a causal role for prenatal androgen exposure in some cases of Autism spectrum disorders (ASD. The ratios of the lengths of the bones of the 2nd to the 4th digits (2D:4D are purported to be markers for prenatal androgen exposure and to be established early in gestation. Ratio of second and fourth digits (2D:4D  is usually used as a proxy for prenatal testosterone. Methods and Materials In this study, 2D:4D in 48 children with ASD and in 41  control child was measured. Two groups were matched with the gender and age. Both groups were selected by convenience sampling method. All statistical analyses were performed using SPSS 19.0 software, considering as significant less than .05 (p < .05. Results: Results showed that the average ratio of 2D:4D in ASD children were lower than the ratio in control children (P

  10. Structural and functional deficits in a neuronal calcium sensor-1 mutant identified in a case of autistic spectrum disorder.

    Directory of Open Access Journals (Sweden)

    Mark T W Handley

    Full Text Available Neuronal calcium sensor-1 (NCS-1 is a Ca(2+ sensor protein that has been implicated in the regulation of various aspects of neuronal development and neurotransmission. It exerts its effects through interactions with a range of target proteins one of which is interleukin receptor accessory protein like-1 (IL1RAPL1 protein. Mutations in IL1RAPL1 have recently been associated with autism spectrum disorders and a missense mutation (R102Q on NCS-1 has been found in one individual with autism. We have examined the effect of this mutation on the structure and function of NCS-1. From use of NMR spectroscopy, it appeared that the R102Q affected the structure of the protein particularly with an increase in the extent of conformational exchange in the C-terminus of the protein. Despite this change NCS-1(R102Q did not show changes in its affinity for Ca(2+ or binding to IL1RAPL1 and its intracellular localisation was unaffected. Assessment of NCS-1 dynamics indicated that it could rapidly cycle between cytosolic and membrane pools and that the cycling onto the plasma membrane was specifically changed in NCS-1(R102Q with the loss of a Ca(2+ -dependent component. From these data we speculate that impairment of the normal cycling of NCS-1 by the R102Q mutation could have subtle effects on neuronal signalling and physiology in the developing and adult brain.

  14. The Embodied Nature of Autistic Learning: Implications for Physical Education

    Directory of Open Access Journals (Sweden)

    Jespersen Ejgil

    2015-03-01

    Full Text Available Autism spectrum disorder (ASD and learning difficulties are difficult to separate in clinic manifestations and diagnoses. By taking learning as being-in-the-world, this article considers the embodied nature of autistic learning and urges its importance for understanding the phenomenological core of ASD. We begin by arguing that three mainstream contemporary ASD theories are inherently limited in offering an adequate account of autistic learning due to the disembodied ontology inscribed within them. Then, we provide an understanding of learning guided by the subjective dynamics of experience. Instead of having a disembodied and individualistic point of view, we suggest that autistic learning has an embodied nature. The “inappropriate” or “abnormal” affections and behaviors in the autistic experience of learning may actually be inherently meaningful for individuals with ASD. They strive to make sense of some basic disturbances and re-establish some form of coherence with the world, though this may only be possible in the form of delusions or autistic withdrawals. Finally, we explore the relationship between autistic learning and physical education and suggest in particular how spontaneous imitation can boost the development of children with ASD. We conclude that the application of implicit learning strategies in playful settings and the reduction of explicit strategies based upon intellectual reasoning rather than bodily reciprocity should be encouraged in the process of autistic learning.

    2016-01-11

    An imbalance between excitatory/inhibitory neurotransmission has been posited as a central characteristic of the neurobiology of autism [1], inspired in part by the striking prevalence of seizures among individuals with the disorder [2]. Evidence supporting this hypothesis has specifically implicated the signaling pathway of the inhibitory neurotransmitter, γ-aminobutyric acid (GABA), in this putative imbalance: GABA receptor genes have been associated with autism in linkage and copy number variation studies [3-7], fewer GABA receptor subunits have been observed in the post-mortem tissue of autistic individuals [8, 9], and GABAergic signaling is disrupted across heterogeneous mouse models of autism [10]. Yet, empirical evidence supporting this hypothesis in humans is lacking, leaving a gulf between animal and human studies of the condition. Here, we present a direct link between GABA signaling and autistic perceptual symptomatology. We first demonstrate a robust, replicated autistic deficit in binocular rivalry [11], a basic visual function that is thought to rely on the balance of excitation/inhibition in visual cortex [12-15]. Then, using magnetic resonance spectroscopy, we demonstrate a tight linkage between binocular rivalry dynamics in typical participants and both GABA and glutamate levels in the visual cortex. Finally, we show that the link between GABA and binocular rivalry dynamics is completely and specifically absent in autism. These results suggest a disruption in inhibitory signaling in the autistic brain and forge a translational path between animal and human models of the condition. PMID:26711497

Four thematic nuclei had been found: (a the family's pilgrimage to health services in order to diagnose their child's condition; (b the ways to deal with the child's difficulties; (c the mother's emotional burden; and (d the parents' helplessness in what concerns future perspectives for the child. Acknowledging such itinerary contributes to improve the planning regarding more specialized programs and services.

  2. Power and Autistic Traits

    Science.gov (United States)

    Overskeid, Geir

    2016-01-01

    Autistic traits can help people gain and sustain power, and has probably done so throughout history, says the present paper. A number of testable claims follow from this assumption. First, the powerful should have more autistic traits than others – which they do appear to have. Among other things, powerful people, and those with many autistic traits, tend to prefer solitary activities and are often aloof. Moreover, they are often rigid and socially insensitive, low on empathy and with low scores on the trait of agreeableness – and as a rule they do not have many friends. Both groups are also more self-centered than others, more honest, less submissive, more sensitive to slights, and with a stronger tendency to engage in abstract thinking. They tend to behave in bossy or dominant ways, and their moral judgment is more based on rules than on feelings. In addition to experimental evidence, I cite biographies showing that a surprising number of presidents, prime ministers and other powerful people seem to have had traits like those in question – and interestingly, in animals, leaders are often rigid and insensitive to group members’ needs and feelings, mostly acting the way they are themselves inclined to, not responding much to others. Problem solving is important in leadership, and people with many autistic traits appear often to be better thinkers than typical subjects with similar IQs. However, these and other congruities could be coincidences. Hence the question of whether traits the two groups have in common also have a common cause constitutes a strong test of the paper’s thesis – and a common cause does appear to exist, in the form of testosterone’s effects on the central nervous system. Finally, there is evidence that, other things equal, powerful men have more reproductive success than others. If men wielding power do indeed have more autistic traits than those less powerful, this will lead to, other things equal, such traits becoming more

  9. 5-HTTLPR Polymorphism: Analysis in South African Autistic Individuals

    2010-06-01

    The serotonin transporter promoter length polymorphism (5-hydroxytryptamine transporter length polymorphism; 5-HTTLPR) has long been implicated in autism and other psychiatric disorders. The use of selective serotonin reuptake inhibitors (SSRIs) has a positive effect on treating some symptoms of autism. The effects of these drugs vary in individuals because of the presence of the S or L allele of 5-HTTLPR. Studies performed on various autistic populations have found different allele frequencies for the L and S alleles. Allele frequencies and genotypes of the South African autistic populations (African, mixed, and Caucasian) were compared with matching South African ethnic control populations. The *S/*S genotype was found to be highly significantly associated with all the South African autistic ethnic populations. In the South African African population the *S/*S genotype was present in 7 (33%) of the autistic individuals but in none of the control subjects, yielding infinitely large odds of developing autism. The odds of developing autism with the *S/*S genotype compared to the *L/*L genotype increased 10.15-fold in the South African mixed group and 2.74-fold in the South African Caucasian population. The allele frequency of the South African autistic population was also compared with studies of other autistic populations around the world, and highly significant differences were found with the Japanese, Korean, and Indian population groups. The difference was not significant for the French, German, Israeli, Portuguese, and American groups. This is the first South African study of autistic individuals of different ethnic backgrounds that shows significant differences in allele and genotype frequencies of 5-HTTLPR. The results of this study open new avenues for investigating the role of transmission of the L and S alleles in families with autism in South Africa.

    Full Text Available Introduction. Conditions in which speech therapy treatment is applied in autistic children are often not in accordance with characteristics of opinions and learning of people with autism. A systemic multimodal approach means motivating autistic people to develop their language speech skill through the procedure which allows reliving of their personal experience according to the contents that are presented in the their natural social environment. This research was aimed at evaluating the efficiency of speech treatment based on the systemic multimodal approach to the work with autistic children. Material and Methods. The study sample consisted of 34 children, aged from 8 to 16 years, diagnosed to have different autistic disorders, whose results showed a moderate and severe clinical picture of autism on the Childhood Autism Rating Scale. The applied instruments for the evaluation of ability were the Childhood Autism Rating Scale and Ganzberg II test. The study subjects were divided into two groups according to the type of treatment: children who were covered by the continuing treatment and systemic multimodal approach in the treatment, and children who were covered by classical speech treatment. Results. It is shown that the systemic multimodal approach in teaching autistic children affects the stimulation of communication, socialization, self-service and work as well as that the progress achieved in these areas of functioning was retainable after long time, too. Conclusion. By applying the systemic multimodal approach when dealing with autistic children and by comparing their achievements on tests applied before, during and after the application of this mode, it has been concluded that certain improvement has been achieved in the functionality within the diagnosed category. The results point to a possible direction in the creation of new methods, plans and programs in dealing with autistic children based on empirical and interactive learning.

    Persons with autistic traits may be at elevated risk for interpersonal victimization across the life course. Children with high levels of autistic traits may be targeted for abuse, and deficits in social awareness may increase risk of interpersonal victimization. Additionally, persons with autistic traits may be at elevated risk of posttraumatic stress disorder (PTSD) symptoms subsequent to trauma. We examined retrospectively reported prevalence of childhood abuse, trauma victimization and PTSD symptoms by autistic traits among adult women in a population-based longitudinal cohort, the Nurses' Health Study II (N=1,077). Autistic traits were measured by the 65-item Social Responsiveness Scale. We estimated odds ratios (OR) for childhood sexual and physical/emotional abuse and PTSD symptoms by quintiles of autistic traits. We examined possible mediation of PTSD risk by abuse and trauma type. Women in the highest versus lowest quintile of autistic traits were more likely to have been sexually abused (40.1% versus 26.7%), physically/emotionally abused (23.9% versus 14.3%), mugged (17.1% versus 10.1%), pressured into sexual contact (25.4% versus 15.6%) and have high PTSD symptoms (10.7% versus 4.5%). Odds of PTSD were elevated in women in the top three quintiles of autistic traits compared with the reference group (OR range=1.4 to 1.9). Childhood abuse exposure partly accounted for elevated risk of PTSD in women with autistic traits. We identify for the first time an association between autistic traits, childhood abuse, trauma victimization, and PTSD. Levels of autistic traits that are highly prevalent in the general population are associated with abuse, trauma and PTSD. PMID:25957197

    The pervasive developmental disorders are a group of neurodevelopmental disorders that include autistic disorder, Asperger's disorder, pervasive developmental disorder - not otherwise specified (PDD-NOS), childhood disintegrative disorder (CDD), and Rett's disorder. All feature childhood onset with a constellation of symptoms spanning social interaction and communication and including atypical behavior patterns. The first three disorders (autistic disorder, Asperger's disorder, and PDD-NOS) are currently referred to as autism spectrum disorders, reflecting divergent phenotypic and etiological characteristics compared to Rett's disorder and CDD. This chapter reviews research and clinical information to appropriate medical diagnosis and treatment. PMID:22608634

    Children with deafness who are also on the autistic spectrum are a group with complex support needs. Carers worry about their ability to communicate with them, and are often uncertain about what constitutes 'good' communication in this context. This paper analyses the use of a therapeutic intervention, Video Interaction Guidance (VIG), which originates in developmental psychology and focuses on the relational foundations of communication. We draw on a single case using an ethnomethodological/conversation analytic framework, and in particular Goodwin's (1994) work on 'professional vision', to show how the ability to see 'success' is a socially situated activity. Since what counts as success in this setting is often far removed from everyday ideas of good communication, how guiders facilitate particular 'ways of seeing' are critical for both the support of carers and the impact of the intervention. We argue that this work has implications in three areas: for the practice of VIG itself; for the role of qualitative, interactional research addressing the way in which interaction-based interventions are protocolised, enacted and assessed; and for the way in which expertise is conceptualised in professional/client interactions in health and social care.

    Full Text Available The pathogenesis of autism, a neurological disorder severely affecting young children, may involve inflammation and autoimmunity. In this report, the distribution of acute-phase C-reactive protein (CRP and S100 proteins was examined in normal and autistic children. Their serum levels were measured by enzyme-linked immunosorbent assay (ELISA. Autistic children were found to have significantly higher than normal levels of CRP (p=0.005 and S100 proteins (p=0.03. The existence of elevated levels of CRP and S100 proteins in autistic children is an excellent sign of systemic inflammation that may contribute to the neuropathology of this brain disorder.

    Full Text Available The rate of Children influenced with extreme autism spectrum disorder (ASD is expanding rapidly. The extremely autistic children confront the issues in comprehension aptitudes, thinking capacity, learning and related abilities. The troubles that the extremely autistic children experience are various. The autistic Children frequently encounter trouble in learning aptitudes, interaction with others and dealing with the social abilities. The most fundamental part of the paper is to examine and to propose the best optimal and ideal features to surmount the learning obstacles and to accelerate the learning capacity of autistic children. The technique proposed comprises of three stages. The First stage identifies the Feature Extraction. The Second stage indicates the Feature Selection. Third stage adopts the classifier methodology. The Principal Component Analysis act as an evaluator in the Feature Extraction. Particle Swarm Optimization is utilized as a Feature Selection. The Particle Swarm Optimization assesses the parameter optimization to retrieve the most effective and best subset of features. The successful best subsets of features are fed into the Support Vector Machine classifier. A definitive result thus emerge show that the proposed technique acquires a higher accuracy with good exactness.

  11. Abstract spatial reasoning as an autistic strength.

    2013-01-01

    Autistic individuals typically excel on spatial tests that measure abstract reasoning, such as the Block Design subtest on intelligence test batteries and the Raven's Progressive Matrices nonverbal test of intelligence. Such well-replicated findings suggest that abstract spatial processing is a relative and perhaps absolute strength of autistic individuals. However, previous studies have not systematically varied reasoning level--concrete vs. abstract--and test domain--spatial vs. numerical vs. verbal, which the current study did. Autistic participants (N = 72) and non-autistic participants (N = 72) completed a battery of 12 tests that varied by reasoning level (concrete vs. abstract) and domain (spatial vs. numerical vs. verbal). Autistic participants outperformed non-autistic participants on abstract spatial tests. Non-autistic participants did not outperform autistic participants on any of the three domains (spatial, numerical, and verbal) or at either of the two reasoning levels (concrete and abstract), suggesting similarity in abilities between autistic and non-autistic individuals, with abstract spatial reasoning as an autistic strength.

    Full Text Available BACKGROUND: Autism is a pervasive neurodevelopmental disorder,thought to be caused by a combination of genetic heritability and environmental risk factors. Some autistic-like traits have been reported in mothers of autistic children. We hypothesized that dysregulation of oxytocin (OXT, Arg-vasopressin (AVP and sex hormones, found in autistic children, may also exist in their mothers. METHODS: We determined plasma levels of OXT (40 in autism vs. 26 in control group, AVP (40 vs. 17 and sex hormones (61 vs. 47 in mothers of autistic and normal children by enzyme immunoassay and radioimmunoassay, respectively and investigated their relationships with the children's autistic behavior scores (Childhood Autism Rating Scale (CARS and Autism Behavior Checklist (ABC. RESULTS: Significantly lower plasma concentrations of OXT (p<0.001 and AVP (p<0.001, as well as a higher level of plasma testosterone (p<0.05, were found in mothers of autistic children vs. those of control. The children's autistic behavior scores were negatively associated with maternal plasma levels of OXT and AVP. CONCLUSIONS: These results suggest that dysregulation of OXT, AVP and/or testosterone systems exist in mothers of autistic children, which may impact children's susceptibility to autism.

    Full Text Available Mutations in the X-linked genes neuroligin 3 (NLGN3 and neuroligin 4X (NLGN4X were first implicated in the pathogenesis of X-linked autism in Swedish families. However, reports of mutations in these genes in autism spectrum disorder (ASD patients from various ethnic backgrounds present conflicting results regarding the etiology of ASD, possibly because of genetic heterogeneity and/or differences in their ethnic background. Additional mutation screening study on another ethnic background could help to clarify the relevance of the genes to ASD. We scanned the entire coding regions of NLGN3 and NLGN4X in 62 Japanese patients with ASD by polymerase chain reaction-high-resolution melting curve and direct sequencing analyses. Four synonymous substitutions, one in NLGN3 and three in NLGN4X, were identified in four of the 62 patients. These substitutions were not present in 278 control X-chromosomes from unrelated Japanese individuals and were not registered in the database of Single Nucleotide Polymorphisms build 132 or in the Japanese Single Nucleotide Polymorphisms database, indicating that they were novel and specific to ASD. Though further analysis is necessary to determine the physiological and clinical importance of such substitutions, the possibility of the relevance of both synonymous and nonsynonymous substitutions with the etiology of ASD should be considered.

    Full Text Available Abstract Background Autism is a disorder of early childhood characterized by social impairment, communication abnormalities and stereotyped behaviors. The hypothalamic-pituitary-adrenocortical (HPA axis deserves special attention, since it is the basis for emotions and social interactions that are affected in autism. Aim To assess basal and stimulated plasma cortisol, and adrenocorticotropic hormone (ACTH levels in autistic children and their relationship to disease characteristics. Methods Fifty autistic children were studied in comparison to 50 healthy age-, sex- and pubertal stage- matched children. All subjects were subjected to clinical evaluation and measurement of plasma cortisol (basal and stimulated and ACTH. In addition, electroencephalography (EEG and intelligence quotient (IQ assessment were done for all autistic children. Results Sixteen% of autistic patients had high ACTH, 10% had low basal cortisol and 10% did not show adequate cortisol response to ACTH stimulation. Autistic patients had lower basal (p = 0.032 and stimulated cortisol (p = 0.04 and higher ACTH (p = 0.01 than controls. Childhood Autism Rating Scale (CARS score correlated positively with ACTH (r = 0.71, p = 0.02 and negatively with each of basal (r = -0.64, p = 0.04 and stimulated cortisol (r = -0.88, p Conclusions The observed hormonal changes may be due to a dysfunction in the HPA axis in autistic individuals. Further studies are warranted regarding the role of HPA axis dysfunction in the pathogenesis of autism.

  17. Reduced incidence of Prevotella and other fermenters in intestinal microflora of autistic children.

    Dae-Wook Kang

    Full Text Available High proportions of autistic children suffer from gastrointestinal (GI disorders, implying a link between autism and abnormalities in gut microbial functions. Increasing evidence from recent high-throughput sequencing analyses indicates that disturbances in composition and diversity of gut microbiome are associated with various disease conditions. However, microbiome-level studies on autism are limited and mostly focused on pathogenic bacteria. Therefore, here we aimed to define systemic changes in gut microbiome associated with autism and autism-related GI problems. We recruited 20 neurotypical and 20 autistic children accompanied by a survey of both autistic severity and GI symptoms. By pyrosequencing the V2/V3 regions in bacterial 16S rDNA from fecal DNA samples, we compared gut microbiomes of GI symptom-free neurotypical children with those of autistic children mostly presenting GI symptoms. Unexpectedly, the presence of autistic symptoms, rather than the severity of GI symptoms, was associated with less diverse gut microbiomes. Further, rigorous statistical tests with multiple testing corrections showed significantly lower abundances of the genera Prevotella, Coprococcus, and unclassified Veillonellaceae in autistic samples. These are intriguingly versatile carbohydrate-degrading and/or fermenting bacteria, suggesting a potential influence of unusual diet patterns observed in autistic children. However, multivariate analyses showed that autism-related changes in both overall diversity and individual genus abundances were correlated with the presence of autistic symptoms but not with their diet patterns. Taken together, autism and accompanying GI symptoms were characterized by distinct and less diverse gut microbial compositions with lower levels of Prevotella, Coprococcus, and unclassified Veillonellaceae.

    Full Text Available Children with autistic spectrum disorders are often encountered in anesthesia practice mainly for outdoor procedural sedation or anesthesia in endoscopy and magnetic resonance imaging suites. We describe a case of a 7-year-old autistic boy who required management of dental caries. He had a phobia to intravenous cannulation, displayed increasing anxiety and became combative on the day of surgery. With parental involvement and distraction, we succeeded in giving oral midazolam by concealing it, with the intent of avoiding intramuscular injection or unnecessary restraint. Lack of knowledge about the medical condition of such a patient can lead to inadequate preoperative preparation and use of restraint on the patient, which might cause anxiety or panic attacks in the operative room. To effectively manage children with special needs one needs to have clear guidelines on the management of uncooperative children, involve parents perioperatively, plan ahead with an emphasis on perioperative analgesia and sometimes incorporate the ethical use of restraint.

    Background: Growth abnormalities are uniquely associated with autism spectrum disorders (ASD); however, the extent to which growth abnormalities are present has hardly been investigated. The current study aims to compare the differences in anthropometric parameters in a group of autistic Egyptian children and the healthy normal population. Methods: We recruited 100 children with ASD from the Outpatient Clinic for "Autistic Children" at the Medical Research Hospital of Excellence, National Research Centre in Cairo, Egypt. They were diagnosed by DSM-IV criteria of the American Psychiatric Association, Autism Diagnostic Interview-Revised, and Childhood Autism Rating Scale. Of these children at age of 3-10 years, 71 were males and 29 females. Eight anthropometric parameters were assessed in view of data of the healthy Egyptians of pertinent sex and age. Results: Weight and body mass index increased because of a signifi cant increase in subcutaneous fat thickness. This tendency with a probable decrease in muscle mass was more evident in male or in older children, likely resulting from sedentary life style and food selectivity. Conclusions: The Z head circumference score and its variance signifi cantly increased especially in males or older children, suggesting the relative overgrowth of the brain in a substantial percentage of Egyptian children with autism. We concluded that increased fat composition in Egyptian autistic children with decreased muscle mass necessitates tailoring a specially designed food supplementation program to ameliorate the severity of autism symptoms.

    Autism is a neurodevelopmental disorder that currently affects as many as 1 out of 166 children in the United States. Recent research has discovered that some autistic individuals have decreased cerebral perfusion, evidence of neuroinflammation, and increased markers of oxidative stress. Multiple independent single photon emission computed tomography (SPECT) and positron emission tomography (PET) research studies have revealed hypoperfusion to several areas of the autistic brain, most notably the temporal regions and areas specifically related to language comprehension and auditory processing. Several studies show that diminished blood flow to these areas correlates with many of the clinical features associated with autism including repetitive, self-stimulatory and stereotypical behaviors, and impairments in communication, sensory perception, and social interaction. Hyperbaric oxygen therapy (HBOT) has been used with clinical success in several cerebral hypoperfusion syndromes including cerebral palsy, fetal alcohol syndrome, closed head injury, and stroke. HBOT can compensate for decreased blood flow by increasing the oxygen content of plasma and body tissues and can even normalize oxygen levels in ischemic tissue. In addition, animal studies have shown that HBOT has potent anti-inflammatory effects and reduces oxidative stress. Furthermore, recent evidence demonstrates that HBOT mobilizes stem cells from human bone marrow, which may aid recovery in neurodegenerative diseases. Based upon these findings, it is hypothesized that HBOT will improve symptoms in autistic individuals. A retrospective case series is presented that supports this hypothesis. PMID:16554123

    In the philosophy of well-being, there is hardly anything written on the lives of people with autism or on the question whether existing philosophical theories of well-being are suited for understanding how well the lives of autistic persons are going. This paper tries to make some progress towards filling this gap. I start by giving a concise account of autism, which highlights the huge heterogeneity among autistics. I discuss some basic features of autism, ask whether there are good reasons why we would need an account of well-being specifically for autistics and what philosophical well-being research could learn from being informed by autistic experiences and phenomenology. I then investigate to what extent the capability approach gives us a helpful theory of well-being for autistics, and what looking through an autism-lens can contribute to the further development of the capabilitarian well-being. In particular, I show that some capabilities that are crucially relevant for autistics are also relevant for the lives of non-autistic people. The final part of the paper looks at an important difficulty in using the capabilitarian account of well-being for autistics, namely: should the normative focus be on achievements (functionings) or real opportunities (capabilities)?

    Full Text Available Abstract Backgrounds Autism is a family of developmental disorders of unknown origin. The disorder is characterized by behavioral, developmental, neuropathological and sensory abnormalities, and is usually diagnosed between the ages of 2 and 10 with peak prevalence rates observed in children aged 5-8 years. Recently, there has been heightened interest in the role of plasma free fatty acids (FA in the pathology of neurological disorders. The aim of this study is to compare plasma fatty acid profiles of Saudi autistic patients with those of age-matching control subjects in an attempt to clarify the role of FA in the etiology of autism. Methods 26 autistic patients together with 26-age-matching controls were enrolled in the present study. Methyl esters of FA were extracted with hexane, and the fatty acid composition of the extract was analyzed on a gas chromatography. Results The obtained data proved that fatty acids are altered in the plasma of autistic patients, specifically showing an increase in most of the saturated fatty acids except for propionic acid, and a decrease in most of polyunsaturated fatty acids. The altered fatty acid profile was discussed in relation to oxidative stress, mitochondrial dysfunction and the high lead (Pb concentration previously reported in Saudi autistic patients. Statistical analysis of the obtained data shows that most of the measured fatty acids were significantly different in autistic patients compared to age -matching controls. Conclusions Receiver Operating Characteristic (ROC curve analysis shows satisfactory values of area under the curve (AUC which could reflect the high degree of specificity and sensitivity of the altered fatty acids as biomarkers in autistic patients from Saudi Arabia.

Recently, it has become possible to link these theories within a common framework. This framework assumes that perception is implicit...... neural inference, combining sensory evidence with prior perceptual knowledge. Within this framework, perceptual differences may occur because of enhanced precision in how sensory evidence is represented, or because sensory evidence is weighted much higher than prior perceptual knowledge...

    A high Autism-Spectrum Quotient (AQ) score (Baron-Cohen et al. in J Autism Dev Disord 31(1):5-17, 2001) is increasingly used as a proxy in empirical studies of perceptual mechanisms in autism. Several investigations have assessed perception in non-autistic people measured for AQ, claiming the same relationship exists between performance on perceptual tasks in high-AQ individuals as observed in autism. We question whether the similarity in performance by high-AQ individuals and autistics reflects the same underlying perceptual cause in the context of two visual search tasks administered to a large sample of typical individuals assessed for AQ. Our results indicate otherwise and that deploying the AQ as a proxy for autism introduces unsubstantiated assumptions about high-AQ individuals, the endophenotypes they express, and their relationship to Autistic Spectrum Conditions (ASC) individuals.

    Full Text Available Objective: Autism is a life long developmental disorder that emerges in early childhood and results in significant lifelong disability. The goal of treatment is to promote the childs social and language development and minimize behaviors that interfere with the childs functioning and learning. This study evaluated the impact of casein and gluten free diet among selected autistic children. Methods: Three private special schools in Salem District, Tamilnadu, India were selected. A total number of 50 autistic children 10 from SIMEC, 10 from MMIC and 30 from CSI comprised the study sample. Background information, clinical history and nutritional status, dietary pattern were collected from the 50 selected autistic children. Out of 50 autistic children 30 autistic children were selected for the dietary intervention. Diet counseling regarding casein free diet was imparted to Group I (n=10, gluten free diet to Group II (n=10 and both casein and gluten free diet for Group III (n=10. The diet was followed for a period of 2 months. The efficacy of the dietary exclusion of casein and gluten was evaluated using a food and behavior diary on a day to day basis, using observation method. Findings: Results about Group I autistic children who followed dietary exclusion of casein free diet showed that the mean scores before and after casein free dietary intervention depiticted these improvements as, 1 to 1.2 for attention, 2.8 to 2.9 for sleep, 1.1 to 1.3 for hyperactivity, 1.1 to 1.2 for anxiety/compulsion. For Group II autistic children who followed dietary exclusion of gluten free diet showed the improvements as 1.1 to 1.4 for attention 2.5 to 3 for sleep, 1.7 to 1.9 for hyperactivity, 1.1 to 1.2 for anxiety/compulsion. About Group III autistic children who followed dietary exclusion of both casein and gluten free diet showed the improvements as 1.1 to 1.3 for attention, 2.5 to 2.7 for sleep, 1.3 to 1.7 for hyperactivity, and 1.1 to 1.2 for anxiety

    Academic achievement levels in 54 high functioning (IQ > 70) autistic subjects were compared with those of 41 normal controls, who did not differ significantly in age, IQ, gender, race, or SES from the autistic subjects. The measures of academic achievement used included portions of the Detroit Tests of Learning Aptitude-2, the Woodcock Reading Mastery Test, and the Kaufman Test of Educational Achievement. Based on prior neuropsychological findings, it was hypothesized that autistic subjects would not differ from controls on subtests assessing mechanical and procedural skills, but would differ on subtests measuring comprehension and interpretive skills. As predicted, the autistic subjects performed significantly less well than controls on comprehension tasks, but not on mechanical reading, spelling, and computational tasks. This pattern is at variance with the typical academic profile of individuals with disabilities in reading or spelling, but shares some features with the nonverbal learning disabilities. PMID:8021313

    Full Text Available Attempts to explicate the neural abnormalities behind autism spectrum disorders frequently revealed impaired brain connectivity, yet our knowledge is limited about the alterations linked with autistic traits in the non-clinical population. In our study, we aimed at exploring the neural correlates of dimensional autistic traits using a dual approach of diffusion tensor imaging (DTI and graph theoretical analysis of resting state functional MRI data. Subjects were sampled from a public neuroimaging dataset of healthy volunteers. Inclusion criteria were adult age (age: 18-65, availability of DTI and resting state functional acquisitions and psychological evaluation including the Social Responsiveness Scale (SRS and Autistic Spectrum Screening Questionnaire (ASSQ. The final subject cohort consisted of 127 neurotypicals. Global brain network structure was described by graph theoretical parameters: global and average local efficiency. Regional topology was characterized by degree and efficiency. We provided measurements for diffusion anisotropy. The association between autistic traits and the neuroimaging findings was studied using a general linear model analysis, controlling for the effects of age, gender and IQ profile. Significant negative correlation was found between the degree and efficiency of the right posterior cingulate cortex and autistic traits, measured by the combination of ASSQ and SRS scores. Autistic phenotype was associated with the decrease of whole-brain local efficiency. Reduction of diffusion anisotropy was found bilaterally in the temporal fusiform and parahippocampal gyri. Numerous models describe the autistic brain connectome to be dominated by reduced long-range connections and excessive short-range fibers. Our finding of decreased efficiency supports this hypothesis although the only prominent effect was seen in the posterior limbic lobe, which is known to act as a connector hub.

  1. Traits contributing to the autistic spectrum.

    Colin D Steer

    Full Text Available BACKGROUND: It is increasingly recognised that traits associated with autism reflect a spectrum with no clear boundary between typical and atypical behaviour. Dimensional traits are needed to investigate the broader autism phenotype. METHODS AND PRINCIPAL FINDINGS: Ninety-three individual measures reflecting components of social, communication and repetitive behaviours characterising autistic spectrum disorder (ASD were identified between the ages of 6 months and 9 years from the ALSPAC database. Using missing value imputation, data for 13,138 children were analysed. Factor analysis suggested the existence of 7 factors explaining 85% of the variance. The factors were labelled: verbal ability, language acquisition, social understanding, semantic-pragmatic skills, repetitive-stereotyped behaviour, articulation and social inhibition. Four factors (1, 3, 5 and 7 were specific to ASD being more strongly associated with this phenotype than other co-morbid conditions while other factors were more associated with learning difficulties and specific language impairment. Nevertheless, all 7 factors contributed independently to the explanation of ASD (p<0.001. Exploration of putative genetic causal factors such as variants in the CNTNAP2 gene showed a varying pattern of associations with these traits. An alternative predictive model of ASD was derived using four individual measures: the coherence subscale of the Children's Communication Checklist (9y, the Social and Communication Disorders Checklist (91 m, repetitive behaviour (69 m and the sociability subscale of the Emotionality Activity and Sociability measure (38 m.

CONCLUSIONS AND SIGNIFICANCE: These results support the fractional nature of ASD with different aetiological origins for these components despite pleiotropic genetic effects being observed.

  3. The autistic brain in the context of normal neurodevelopment

    Full Text Available The etiology of autism spectrum disorders (ASD is complex and largely unclear. Among various lines of inquiry, many have suggested convergence onto disruptions in both neural circuitry and immune regulation/glial cell function pathways. However, the interpretation of the relationship between these two putative mechanisms has largely focused on the role of exogenous factors and insults, such as maternal infection, in generating activating immune pathways that in turn result in neural network abnormalities. Yet, given recent insights in our understanding of human neurodevelopment, and in particular the critical role of glia and the immune system in normal brain development, it is important to consider these putative pathological processes in their appropriate normal neurodevelopmental context. In this review, we explore the hypothesis that the autistic brain cellular phenotype likely represents intrinsic abnormalities of glial/immune processes constitutively operant in normal brain development that result in the observed neural network dysfunction. We review recent studies demonstrating the intercalated role of neural circuit development, the immune system, and glial cells in the normal developing brain, an integrate them with studies demonstrating pathological alterations in these processes in autism. By discussing known abnormalities in the autistic brain in the context of normal brain development, we explore the hypothesis that the glial/immune component of ASD may instead be related to intrinsic exaggerated/abnormal constitutive neurodevelopmental processes such as network pruning. Moreover, this hypothesis may be relevant to other neurodevelopmental disorders that share genetic, pathologic, and clinical features with autism.

    The prevalence of autism spectrum disorder (ASD) has risen significantly in the last ten years, and today, roughly 1 in 68 children has been diagnosed. One hallmark set of symptoms in this disorder are stereotypical motor movements. These repetitive movements may include spinning, body-rocking, or hand-flapping, amongst others. Despite the growing number of individuals affected by autism, an effective, accurate method of automatically quantifying such movements remains unavailable. This has negative implications for assessing the outcome of ASD intervention and drug studies. Here we present a novel approach to detecting autistic symptoms using the Microsoft Kinect v.2 to objectively and automatically quantify autistic body movements. The Kinect camera was used to film 12 actors performing three separate stereotypical motor movements each. Visual Gesture Builder (VGB) was implemented to analyze the skeletal structures in these recordings using a machine learning approach. In addition, movement detection was hard-coded in Matlab. Manual grading was used to confirm the validity and reliability of VGB and Matlab analysis. We found that both methods were able to detect autistic body movements with high probability. The machine learning approach yielded highest detection rates, supporting its use in automatically quantifying complex autistic behaviors with multi-dimensional input. PMID:27046572

  5. Short report: autistic gastrointestinal and eating symptoms treated with secretin: a subtype of autism

    Full Text Available Abstract Pervasive Developmental Disorders (PDD are chronic, lifelong disorders for which there is as yet no effective cure, and medical management remains a challenge for clinicians. The current report describes two patients affected by autistic disorder with associated gastrointestinal symptoms. They received multiple doses of intravenous secretin for a six-month period and were assessed with several specific outcome measures to evaluate drug effect. The administration of secretin led to some significant and lasting improvement in only one case. Gastroesophageal reflux may contribute to some of the behavioural problems and explain the effect of secretin since its suppressive effect on gastric secretion is well known. It is also true that autistic children with gastroesophageal reflux and a higher IQ could constitute a subtype which responds to secretin administration and that could be labelled as a "gastrointestinal subtype".

  6. Age-related decreased inhibitory versus excitatory gene expression in the adult autistic brain

    Full Text Available Autism spectrum disorders (ASDs are neurodevelopmental disorders characterised by impaired social interaction and communication, and restricted behaviour and interests. A disruption in the balance of excitatory and inhibitory neurotransmission has been hypothesised to underlie these disorders. Here we demonstrate that genes of both pathways are affected by ASD, and that gene expression of inhibitory and excitatory genes is altered in the cerebral cortex of adult but not younger autistic individuals. We have developed a measure for the difference in the level of excitation and inhibition based on gene expression and observe that in this measure inhibition is decreased relative to excitation in adult ASD compared to control. This difference was undetectable in young autistic brains. Given that many psychiatric features of autism are already present at an early age, this suggests that the observed imbalance in gene expression is an ageing phenomenon in ASD rather than its underlying cause.

  12. Fmr1 KO Mice as a Possible Model of Autistic Features

    2006-01-01

    Full Text Available Autism is a pervasive developmental disorder appearing before the age of 3, where communication and social interactions are impaired. It also entails stereotypic behavior or restricted interests. Although this disorder was first described in 1943, little is still known about its etiology and that of related developmental disorders. Work with human patients has provided many data on neuropathological and cognitive symptoms, but our understanding of the functional defects at the cellular level and how they come about remains sketchy. To improve this situation, autism research is in need of valid animal models. However, despite a strong hereditary component, attempts to identify genes have generally failed, suggesting that many different genes are involved. As a high proportion of patients suffering from the Fragile X Syndrome show many autistic symptoms, a mouse model of this disorder could potentially also serve as a model for autism. The Fmr1 KO mouse is a valid model of the Fragile X Syndrome and many data on behavioral and sensory-motor characteristics of this model have been gathered. We present here an assessment of autistic features in this candidate model. We conclude that Fmr1 KO mice display several autistic-like features, but more work is needed to validate this model.

    Objective To assess autism spectrum disorder (ASD) behaviors in children with mucopolysaccharidosis Type IIIA (MPS IIIA), using a standard measure, understand the behavioral evolution of the disease, and provide specific guidelines for diagnosis. Study design Children (n=21) with documented enzyme deficiency and SGSH gene mutations, cognitive age-equivalent over 12 months, and early onset were administered the Autism Diagnostic Observation Schedule (ADOS) (Module 1) and Bayley Scales of Infant Development–III (BSID-III). ADOS Social Affect and Restricted Repetitive Behavior total scores are reported as well as BSID-III cognitive age-equivalent using descriptive statistics and graphic presentations. Results Thirteen of 21 children met ADOS criteria for ASD/autism. ADOS score was strongly associated with age; all 11 children over 46 months met criteria, and 8 of 10 under 46 months did not. Social and affective abnormalities were most frequent; restricted interests and repetitive behaviors were largely absent. Lack of cognitive growth paralleled ADOS score. Conclusions An increased incidence of autistic-like social behaviors occurred between ages 3 and 4 in children with early onset MPS IIIA. Although more frequent in the severely impaired, ASD behaviors were observed across the entire range of cognitive impairment. Clinicians must be aware that when a child acquires autistic-like behaviors, MPS IIIA should be included in the differential diagnosis. PMID:24582005

  14. Does bilateral damage to the human amygdala produce autistic symptoms?

    2010-09-01

    A leading neurological hypothesis for autism postulates amygdala dysfunction. This hypothesis has considerable support from anatomical and neuroimaging studies. Individuals with bilateral amygdala lesions show impairments in some aspects of social cognition. These impairments bear intriguing similarity to those reported in people with autism, such as impaired recognition of emotion in faces, impaired theory of mind abilities, failure to fixate eyes in faces, and difficulties in regulating personal space distance to others. Yet such neurological cases have never before been assessed directly to see if they meet criteria for autism spectrum disorders (ASD). Here we undertook such an investigation in two rare participants with developmental-onset bilateral amygdala lesions. We administered a comprehensive clinical examination, as well as the Autism Diagnostic Observation Schedule (ADOS), the Social Responsiveness Scale (SRS), together with several other standardized questionnaires. Results from the two individuals with amygdala lesions were compared with published norms from both healthy populations as well as from people with ASD. Neither participant with amygdala lesions showed any evidence of autism across the array of different measures. The findings demonstrate that amygdala lesions in isolation are not sufficient for producing autistic symptoms. We suggest instead that it may be abnormal connectivity between the amygdala and other structures that contributes to autistic symptoms at a network level. PMID:20700516

    Although not a core symptom of the disorder, individuals with autism often exhibit selective impairments in their face processing abilities. Importantly, the reciprocal connection between autistic traits and face perception has rarely been examined within the typically developing population. In this study, university participants from the social sciences, physical sciences, and humanities completed a battery of measures that assessed face, object and emotion recognition abilities, general perceptual-cognitive style, and sub-clinical autistic traits (the Autism Quotient (AQ)). We employed separate hierarchical multiple regression analyses to evaluate which factors could predict face recognition scores and AQ scores. Gender, object recognition performance, and AQ scores predicted face recognition behaviour. Specifically, males, individuals with more autistic traits, and those with lower object recognition scores performed more poorly on the face recognition test. Conversely, university major, gender and face recognition performance reliably predicted AQ scores. Science majors, males, and individuals with poor face recognition skills showed more autistic-like traits. These results suggest that the broader autism phenotype is associated with lower face recognition abilities, even among typically developing individuals. PMID:24853862

    Full Text Available Neonatal isolation is a widely accepted model to study the long-term behavioral changes produced by the early life events. However, it remains unknown whether neonatal isolation can induce autistic-like behaviors, and if so, whether pharmacological treatment can overcome it. Here, we reported that newborn rats subjected to individual isolations from their mother and nest for 1 hr per day from postnatal days 1 to 9 displayed apparent autistic-like symptoms including social deficits, excessive repetitive self-grooming behavior, and increased anxiety- and depressive-like behaviors tested in young adult (postnatal days 42-56 compared to normal reared controls. Furthermore, these behavioral changes were accompanied by impaired adult hippocampal neurogenesis and reduced the ratio of excitatory/inhibitory synaptic transmissions, as reflected by an increase in spontaneous inhibitory postsynaptic current (sIPSC and normal spontaneous excitatory postsynaptic current (sEPSC in the hippocampal CA1 pyramidal neuron. More importantly, chronic administration of lithium, a clinically used mood stabilizer, completely overcame neonatal isolation-induced autistic-like behaviors, and restored adult hippocampal neurogenesis as well as the balance between excitatory and inhibitory activities to physiological levels. These findings indicate that neonatal isolation may produce autistic-like behaviors, and lithium may be a potential therapeutic agent against autism spectrum disorders during development.

  18. Synchrony Between Sensory and Cognitive Networks is Associated with Subclinical Variation in Autistic Traits

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available Individuals with autistic spectrum disorders exhibit distinct personality traits linked to attentional, social, and affective functions, and those traits are expressed with varying levels of severity in the neurotypical and subclinical population. Variation in autistic traits has been linked to reduced functional and structural connectivity (i.e., underconnectivity, or reduced synchrony with neural networks modulated by attentional, social, and affective functions. Yet, it remains unclear whether reduced synchrony between these neural networks contributes to autistic traits. To investigate this issue, we used functional magnetic resonance imaging to record brain activation while neurotypical participants who varied in their subclinical scores on the Autism-Spectrum Quotient (AQ viewed alternating blocks of social and nonsocial stimuli (i.e., images of faces and of landscape scenes. We used independent component analysis combined with a spatiotemporal regression to quantify synchrony between neural networks. Our results indicated that decreased synchrony between the executive control network and a face-scene network predicted higher scores on the AQ. This relationship was not explained by individual differences in head motion, preferences for faces, or personality variables related to social cognition. Our findings build on clinical reports by demonstrating that reduced synchrony between distinct neural networks contributes to a range of subclinical autistic traits.

  6. Accommodating Autistics and Treating Autism: Can We Have Both?

    Science.gov (United States)

    Lim, Chong-Ming

    2015-10-01

    One of the central claims of the neurodiversity movement is that society should accommodate the needs of autistics, rather than try to treat autism. People have variously tried to reject this accommodation thesis as applicable to all autistics. One instance is Pier Jaarsma and Stellan Welin, who argue that the thesis should apply to some but not all autistics. They do so via separating autistics into high- and low-functioning, on the basis of IQ and social effectiveness or functionings. I reject their grounds for separating autistics. IQ is an irrelevant basis for separating autistics. Charitably rendering it as referring to more general capacities still leaves us mistaken about the roles they play in supporting the accommodation thesis. The appeal to social effectiveness or functionings relies on standards that are inapplicable to autistics, and which risks being deaf to the point of their claims. I then consider if their remaining argument concerning autistic culture may succeed independently of the line they draw. I argue that construing autistics' claims as beginning from culture mistakes their status, and may even detract from their aims. Via my discussion of Jaarsma and Welin, I hope to point to why the more general strategy of separating autistics, in response to the accommodation thesis, does not fully succeed. Finally, I sketch some directions for future discussions, arguing that we should instead shift our attention to consider another set of questions concerning the costs and extent of change required to accommodate all autistics.

    Full Text Available Abstract Introduction Autism is complex neuro-developmental disorder which has a symptomatic diagnosis in patients characterized by disorders in language/communication, behavior, and social interactions. The exact causes for autism are largely unknown, but is has been speculated that immune and inflammatory responses, particularly those of Th2 type, may be involved. Thiazolidinediones (TZDs are agonists of the peroxisome proliferator activated receptor gamma (PPARγ, a nuclear hormone receptor which modulates insulin sensitivity, and have been shown to induce apoptosis in activated T-lymphocytes and exert anti-inflammatory effects in glial cells. The TZD pioglitazone (Actos is an FDA-approved PPARγ agonist used to treat type 2 diabetes, with a good safety profile, currently being tested in clinical trials of other neurological diseases including AD and MS. We therefore tested the safety and therapeutic potential of oral pioglitazone in a small cohort of children with diagnosed autism. Case description The rationale and risks of taking pioglitazone were explained to the parents, consent was obtained, and treatment was initiated at either 30 or 60 mg per day p.o. A total of 25 children (average age 7.9 ± 0.7 year old were enrolled. Safety was assessed by measurements of metabolic profiles and blood pressure; effects on behavioral symptoms were assessed by the Aberrant Behavior Checklist (ABC, which measures hyperactivity, inappropriate speech, irritability, lethargy, and stereotypy, done at baseline and after 3–4 months of treatment. Discussion and evaluation In a small cohort of autistic children, daily treatment with 30 or 60 mg p.o. pioglitazone for 3–4 months induced apparent clinical improvement without adverse events. There were no adverse effects noted and behavioral measurements revealed a significant decrease in 4 out of 5 subcategories (irritability, lethargy, stereotypy, and hyperactivity.

    Full Text Available We used a national online registry to examine variation in cumulative prevalence of community diagnosis of psychiatric comorbidity in 4343 children with autism spectrum disorders (ASD. Adjusted multivariate logistic regression models compared influence of individual, family, and geographic factors on cumulative prevalence of parent-reported anxiety disorder, depression, bipolar disorder, and attention deficit/hyperactivity disorder or attention deficit disorder. Adjusted odds of community-assigned lifetime psychiatric comorbidity were significantly higher with each additional year of life, with increasing autism severity, and with Asperger syndrome and pervasive developmental disorder—not otherwise specified compared with autistic disorder. Overall, in this largest study of parent-reported community diagnoses of psychiatric comorbidity, gender, autistic regression, autism severity, and type of ASD all emerged as significant factors correlating with cumulative prevalence. These findings could suggest both underlying trends in actual comorbidity as well as variation in community interpretation and application of comorbid diagnoses in ASD.

    Full Text Available In a sample of 51 teenagers with anorexia nervosa (AN—which included 24 cases constituting the total population of AN cases born in 1970—several had shown social, communicative and behaviour patterns suggestive of autistic-like conditions as children, long before the onset of AN. One of the three boys in the AN group had Asperger syndrome. Three of the 48 girls had histories suggesting high functioning autism and continued to show many features typical of autism. Two further girls had Tourette syndrome and obsessive–compulsive traits in combination with social interaction problems. Eighteen other girls met criteria for obsessive–compulsive personality disorder (OCPD and most of these also had had moderate–severe childhood social interaction problems. In a sex- and age-matched comparison group from the same schools, two girls had OCPD, but none had autistic-like conditions or Tourette syndrome. The results are discussed in the context of a recently suggested link between Asperger syndrome, Tourette syndrome and obsessive–compulsive problems, and it is suggested that AN in a subgroup of cases might represent a disorder belonging in the same class as autism and autistic-like conditions.

    Approximately 50% of all individuals with Autism have difficulties in developing functional language owing to communication deterioration. Mobile devices with installed educational games help these individuals feel more comfortable and relaxed doing such activities. Although numerous mobile applications are available for individuals with Autism, they are difficult to use; particularly in terms of user-interface design. From the analysis of existing apps for autistic children, an app design principles are proposed based on interaction design (IxD), that would fulfil the users' requirements in a better manner. Five applications were involved in this analysis. The analysis identified fifteen suggestions for the design principles. These recommendations are offered by this paper towards designing and developing a prototype app for autistic children. This paper introduces an edutainment-system design principle formulated to help develop the communication skills of children with Autism-spectrum disorders.

    Full Text Available Background and Aim: Autism is a pervasive developmental disorder with several speech disorders such as prosodic and pragmatic impairments. Melodic intonation therapy (MIT based on Albert et al. model (1973 is a rehabilitation method, developed on prosodic features. The aim of this study was to investigate the effects of MIT on Persian autistic children’s prosody.Methods: An easy version of MIT, adopted for Persian language was designed by researchers. Then, after a successful pilot study on a 10-years-old boy for one month, 13 subjects were selected for the main study. All the subjects were autistic, male, right-handed, 7-10-years-old Persian children studied for 48 sessions (16 weeks. Background information gathered from the parents by a questionnaire. As pre- and post-test, some assessments about children’s fundamental frequency (Fº and intensity of the Persian vowel sounds and declarative and interrogative sentences were accomplished. The data analysis was done using Praat and SPSS softwares.Results: There was a statistically significant increase in acoustic features, such as intensity, and fundamental frequency of declarative and interrogative sentences; also all six vowels of Persian, excluding /â/ and /æ/ (p<0.05 for all.Conclusion: The widely reported unusual prosody in autistic children was quantified by this study, too. In addition, there was convincing evidence of the positive effects of melodic intonation therapy on acoustic features in Persian autistic children.

    Going on a car with autistic children needs a special handling. Autistic children that tend to be hyperactive in the car may disturb driving. A tool is needed to keep them in a calm state when they are in the car. Autist Mobile Seat is an aid for the autistic children when going on a car. The aid is an additional seat paired with the main seat of the car. This aid consists of three main things: Main frame, body skin, and pneumatic system. Frame as the main component supporting the Autist Mobile Seat functions as a holder as well as a body skin retainer in order to be able to retain the body of the autistic children. The strength of the frame from this Autist Mobile Seat should be counted as an anticipation from the failure of the frame function when receiving load when used by the autistic children in the car. Consequently, a test on the frame of the Autist Mobile Seat towards the load received should be conducted by using a method of FEM (Finite Element Method) with the help of commercial software. The simulation produces the maximum strength, the frame towards the load received as well as the critical point on the frame when loading occurs.

  18. Imitation and social responsiveness in autistic children.

    1984-06-01

    Fifteen autistic children, ages 4-6 years, participated in the present study. Imitation and object permanence skills were assessed. Language and social behaviors were observed during free play. Children were also exposed to three interactive procedures that differed in developmental sophistication. The experimenter either (1) simultaneously imitated the child's actions, (2) modeled a familiar action, or (3) modeled a novel action. It was found that the autistic children who had a low level of imitative ability (Piaget's Stages 2-3) were more socially responsive, showed more eye contact, and played with toys in a less perseverative manner when the experimenter imitated their behavior than when the experimenter modeled either a familiar or a novel action. When the experimenter modeled a familiar as opposed to a novel action, these children were more likely to spontaneously imitate the experimenter. The autistic children with more highly developed imitation skills, however, responded similarly to all conditions. They also were generally more socially and verbally responsive. These results suggest that developmental status is an important variable in designing intervention programs for severely impaired children. PMID:6725782

    Full Text Available Multiple functional imaging techniques help to a better understanding of the neurobiological basis of autism-spectrum disorders (ASD. The early functional imaging studies on ASD focused on task-specific methods related to core symptom domains and explored patterns of activation in response to face processing, theory of mind tasks, language processing and executive function tasks. On the other hand, fMRI research in ASD focused on the development of functional connectivity methods and has provided evidence of alterations in cortical connectivity in ASD and establish autism as a disorder of under-connectivity among the brain regions participating in cortical networks. This atypical functional connectivity in ASD results in inefficiency and poor integration of processing in network connections to achieve task performance. The goal of this review is to summarise the actual neuroimaging functional data and examine their implication for understanding of the neurobiology of ASD.

    The data on the rate of brain imaging abnormalities in autistic spectrum disorders are still inconsistent. A recent study on patients with high-functioning autism found that approximately 90% of children had normal magnetic resonance imaging (MRI) scans whereas an unexpected high rate of MRI abnormalities was reported in 77 nonsyndromic autistic children with or without intellectual disability. The aim of this study was to evaluate the prevalence of neuroradiologic findings in low-functioning autistic children compared to controls matched for age. Minor brain abnormalities were found in 44% of patients and 22% of controls. Our main result is the high rate of mega cisterna magna in autistic patients. High rate of minor neuroradiologic abnormalities in low-functioning autistic patients could contribute to the research about the various endophenotypes and complete the clinical assessment of children with autistic spectrum disorder and intellectual disability.

    Full Text Available Research suggests that offspring of mothers who experience high levels of stress during pregnancy are more likely to have problems in neurobehavioural development. There is preliminary evidence that prenatal maternal stress (PNMS is a risk factor for both autism and ADHD, however most studies do not control for confounding factors and no study has investigated PNMS as a risk factor for behaviors characteristic of these disorders in early childhood. A population cohort of 2900 pregnant women were recruited before their 18th week of pregnancy and investigated prospectively. Maternal experience of stressful life events was assessed during pregnancy. When offspring were age 2-years, mothers completed the Child Behavior Checklist. Multiple regression showed that maternal stressful events during pregnancy significantly predicted ADHD behaviours in offspring, after controlling for autistic traits and other confounding variables, in both males (p= .03 and females (p= .01. Similarly, stressful events during pregnancy significantly predicted autistic traits in the offspring after controlling for ADHD behaviours and confounding variables, in males only (p= .04. In conclusion, this study suggests that PNMS, in the form of typical stressful live events such as divorce or a residential move, show a small but significant association with both autistic traits and ADHD behaviours independently, in offspring at age 2 years, after controlling for multiple antenatal, obstetric, postnatal and sociodemographic covariates. This finding supports future research using epigenetic, cross-fostering, and gene-environment interaction designs to identify the causal processes underlying this association.

    About 10% of autistic individuals exhibit some form of islets of abilities in the face of serious intellectual or mental disability ("savant syndrome"). The aim of this study was to investigate brain mechanisms in a sample of autistic subjects with outstanding memory. We investigated seven mnemonist savants with high-functioning autism spectrum disorder and seven matched controls with 151-channel whole-head magnetencephalography in a continuous old-new paradigm. They were presented with 300 pseudowords and 300 shapes and had to indicate by button press, whether the presented stimulus had been shown before. Unexpectedly, mnemonist savants did not perform better than controls, but were outperformed in the recognition of pseudowords. Accordingly, event-related magnetic fields elicited by pseudowords showed widespread old-new effects in controls, but not in savants. A source analysis of its early components revealed right occipital activation in savants, but left parietal activation in controls. This might be related to a visual processing style in mnemonist savants that proved to be inefficient in this task. During the possibly familiarity-based recognition of shapes, there were earlier and more widespread bilateral old-new effects in mnemonist savants, what might reflect their experience with figural material. In a neuropsychological test battery, mnemonist savants performed comparably to autistic people without special memory skills. However, a different factor structure of these tests pointed to a different organization of memory in mnemonist savants compared to controls that is characterized by its relative independence of general intelligence.

    Autism is a neurodevelopmental disorder characterized by marked deficits in communication, social interaction, and interests. Various studies of autism have suggested abnormalities in several brain regions, with an increasing agreement on the abnormal anatomy of the white matter (WM) and on deficits in the size of the corpus callosum (CC) and its sub-regions in autism. In this paper, we aim at using these abnormalities in order to devise robust classification methods of autistic vs. typically developing brains by analyzing their respective MRIs. Our analysis is based on shape descriptions and geometric models. We compute the 3D distance map to describe the shape of the WM, and use it as a statistical feature to discriminate between the two groups. We also use our recently proposed non-rigid registration technique to devise another classification approach by statistically analyzing and comparing the deformation fields generated from registering segmented CC's onto each others. The proposed techniques are tested on postmortem and on in-vivo brain MR data. At the 85% confidence level the WM-based classification algorithm correctly classified 14/14 postmortem-autistics and 12/12 in-vivo autistics, a 100% accuracy rate, and 13/15 postmortem controls (86% accuracy rate) and 30/30 in-vivo controls (100% accuracy rate). The technique based on the analysis of the CC was applied only on the in vivo data. At the 85% confidence rate, this technique correctly classified 10/15 autistics, a 0.66 accuracy rate, and 29/30 controls, a 0.96 accuracy rate. These results are very promising and show that, contrary to traditional methods, the proposed techniques are less sensitive to age and volume effects. (orig.)

    Full Text Available The McGurk effect is a well-known illustration that demonstrates the influence of visual information on hearing in the context of speech perception. Some studies have reported that individuals with autism spectrum disorder (ASD display abnormal processing of audio-visual speech integration, while other studies showed contradictory results. Based on the dimensional model of ASD, we administered two analog studies to examine the link between level of autistic traits, as assessed by the Autism Spectrum Quotient (AQ, and the McGurk effect among a sample of university students. In the first experiment, we found that autistic traits correlated negatively with fused (McGurk responses. Then, we manipulated presentation types of visual stimuli to examine whether the local bias toward visual speech cues modulated individual differences in the McGurk effect. The presentation included four types of visual images, comprising no image, mouth only, mouth and eyes, and full face. The results revealed that global facial information facilitates the influence of visual speech cues on McGurk stimuli. Moreover, individual differences between groups with low and high levels of autistic traits appeared when the full-face visual speech cue with an incongruent voice condition was presented. These results suggest that individual differences in the McGurk effect might be due to a weak ability to process global facial information in individuals with high levels of autistic traits.

  12. The theory of transformations and autistic states. Autistic transformations: a proposal.

    Fix Korbivcher, Celia

    2005-12-01

    This work integrates two areas of thinking: one in which the author develops considerations regarding observation methods of mental phenomena in psychoanalysis according to Bion's theory of transformations; the other in which she is concerned with the investigation of primitive mental states--protomental states--more specifically, the autistic states of neurotic patients, described by Tustin. Some ideas on the 'philosophical' position underlying transformations theory are elaborated, particularly emphasizing the idea that the same phenomenon in psychoanalysis may be considered from different perspectives, as long as it is situated within the theoretical reference frame to which it belongs. The author considers the idea that this method of phenomenon observation is part of a wider context of general human knowledge, in which uncertainty and relativity of concepts are the main components. By adopting transformations theory as a perspective of phenomena observation that pervades the analytical meeting, the author questions whether it is possible to include other groups of transformation of emotional experiences in this theory, which shows particular phenomena with specific qualities, distinct from those emphasized by Bion. She hypothesizes that autistic phenomena present in neurotic patients, characterizing autistic states, may be considered and detached, making up a particular group of transformation of emotional experience, which analysts often face in their daily practice. She names this group 'autistic transformations'. PMID:16318939

    1993-11-01

    A dysfunctional attention hypothesis of the basis of savant skills was tested with a series of computerized tasks that assessed the ability to divide, shift, direct, and sustain attention. Ten healthy men with pervasive developmental disorders and unusual calendar-calculating skill, and 10 age- and sex-matched controls were tested. There were four general findings. First, the savants and controls did not differ on a measure of visual sustained attention. Second, the savants failed to detect rare auditory targets significantly more than did the controls. Third, the savants were unable to efficiently divide their attention when required to detect both visual and auditory targets simultaneously. Finally, deficient orienting or a deficit in shifting selective attention from one stimulus location to another was evidenced in overall slower reaction times for the savants across tasks requiring shifts and redirecting of attention. This deficit was attributed to an inability to disengage attention as a result of deficient orienting and overselectivity. PMID:8120129

    This article describes a pilot project whose objective was to explore whether the Webster-Stratton Parenting Programme may be effective for hearing parents and their deaf children who present with conduct disorders and other emotional, behavioural and developmental problems. Outcome measures aimed at overall impact in decreasing behavioural problems and improving overall family function were used. Participants were hearing parents of deaf children referred to our specialist service whose assessment had recommended a parenting skills group as treatment of choice. The children had been diagnosed with behavioural problems with or without additional comorbidity. This pilot phase focused deliberately on one participant, in order to explore whether the approach justified further, more comprehensive evaluative research. Outcome was positive, suggesting that modified Webster-Stratton approaches may well be of use in deaf children of hearing parents. PMID:17375814

    Full Text Available Objectives. To analyze cooccurring disorders and problems in a representative group of 198 preschool children with autism spectrum disorders (ASD who had had interventions at a specialized habilitation center. Methods. Parents and children were seen by a research team. Data were based on parental interviews, pediatric assessments, and tests of the child. Information on autistic symptoms, general cognitive function, speech and language, motor function, epilepsy, vision, hearing, activity level, behavior, and sleep was collected. Results. Three ASD categories were used: (1 autistic disorder (AD, (2 autistic-like condition (ALC or Asperger syndrome, and (3 one group with autistic symptoms/traits but not entirely all its criteria met for ASD. Children with autism had a mean of 3.2 coexisting disorders or problems, the ALC/Asperger group had a mean of 1.6, and children with autistic traits had a mean of 1.6. The most common disorder/problems in the total group pertained to language problems (78%, intellectual disability (ID (49%, below average motor function (37%, and severe hyperactivity/ADHD (33%. Conclusions. The results accord with the concept of early symptomatic syndromes eliciting neurodevelopmental clinical examination (ESSENCE, and highlight the need of considering ASD in a broad perspective taking also other cooccurring developmental disorders into account.

    Voxel-based morphometry (VBM) studies have reported abnormalities in brain regions involved in functions that are commonly impaired in autism spectrum disorders (ASD). However, little is known about brain structure anomalies in low-functioning (LF) young children with ASD. A VBM analysis was carried out to assess brain regions involved in ASD LF children, and a multiple regression analysis was used to examine the relationship between regional volume changes and autism symptom measures. Twenty-six LF ASD children (2-10 years) were compared with 21 controls. A VBM-Diffeomorphic Anatomical Registration analysis using Exponentiated Lie algebra (DARTEL) was used to evaluate gray matter (GM) and white matter alterations, covaried with Intelligence Quotient, age, and total brain volume. The resulting altered regions were correlated with Autism Diagnostic Interview (ADI)-Revised and Autism Diagnostic Observation Schedule (ADOS)-Generic scores. GM bilateral reduction was noted in the cerebellum (Crus II and vermis) and in the hippocampi in ASD group. GM reduction was also detected in the inferior and superior frontal gyri, in the occipital medial and superior gyri, and in the inferior temporal gyrus of the left cerebral hemisphere. In the right hemisphere, GM reduction was found in the post-central cortex and in the occipital inferior gyrus. Multiple regression analysis showed a correlation between alterations in GM volume in the cerebellum (Crus II and vermis) and ADI-communication and ADOS-total (communication and interaction) scores. These findings seem to confirm that the cerebellum is involved in integrating and regulating emotional and cognitive functions which are impaired in ASD. PMID:23572290

  18. Study on CT changes in autistic children

    International Nuclear Information System (INIS)

    Since 1979 we have performed CT examinations on 132 autistic children. Neurological diagnosis of the lesion was established by Dr. Segawa's group. On the CT of many autistic children, we found a small low density change located in the anterior wall of the temporal horn, or localized dilatation of the inferior horn near the damaged brain. We reviewed 96 of these patients who all had the obvious low density changes, or localized irregular dilatations in the anterior wall of the temporal horn. By measuring the distance of damage from the midline, we divided the 96 cases into two groups. Group 1 consisted of those with damage located laterally more than 30 mm line from the midline. Group 2 consisted of those with damage medially to the 30 mm line from the midline. Those cases with a large lesion both laterally and medially of the 30 mm line were categorized into group 1. In the adult brain the lateral border of the amygdaloid nucleus was never located laterally more than 30 mm from the midline. Laterally over the 30 mm line there were two marked fiber systems running near the anterior wall of the temporal horn: the fiber of the anterior commissure and the uncinate fascicle. Group 1 consisted of 62 patients and group 2 of 34 patients. The majority of the two group patients were pure autism children. This suggested that the main lesion in autism was in the amygdala.

We investigated the shared phenotype at a personality trait level, particularly its resemblance to schizoid personality disorder, as well as differential aspects of the autism-schizophrenia model.Items of the Autism Spectrum Quotient (AQ and Schizotypal Personality Questionnaire (SPQ were pseudo-randomly combined, and were completed by 449 (162 male, 287 female non-clinical participants aged 18-40. A Factor Analysis revealed three factors; the first represented a shared social disorganization phenotype, the second reflected perceptual oddities specific to schizotypy while the third reflected social rigidity specific to autism. The AQ and SPQ were strongly correlated with Factor 1 (AQ: r=.75, p<.001; SPQ: r=.96, p<.001, SPQ score was correlated with Factor 2 (r=.51, p<.001, particularly in Cognitive-Perceptual features (r=.66, p<.001, and AQ score was strongly correlated with Factor 3 (r=.76, p<.001. Furthermore, there was no relationship between Factor 1 and Factor 2.Thus, there is robust evidence for a shared social disorganization phenotype in autistic and schizotypal tendency, which reflects the schizoid phenotype. Discriminating and independent dimensions of schizotypal and autistic tendency exist in Factors 2 and 3 respectively. Current diagnostic protocols could result in different diagnoses depending on the instrument used, suggesting the need for neuromarkers that objectively differentiate autistic and schizotypal traits and resolve the question of commonality versus comorbidity.

    Research suggests that offspring of mothers who experience high levels of stress during pregnancy are more likely to have problems in neurobehavioral development. There is preliminary evidence that prenatal maternal stress (PNMS) is a risk factor for both autism and attention deficit hyperactivity disorder (ADHD), however most studies do not control for confounding factors and no study has investigated PNMS as a risk factor for behaviors characteristic of these disorders in early childhood. A population cohort of 2900 pregnant women were recruited before their 18th week of pregnancy and investigated prospectively. Maternal experience of stressful life events was assessed during pregnancy. When offspring were age 2 years, mothers completed the child behavior checklist. Multiple regression showed that maternal stressful events during pregnancy significantly predicted ADHD behaviors in offspring, after controlling for autistic traits and other confounding variables, in both males (p = 0.03) and females (p = 0.01). Similarly, stressful events during pregnancy significantly predicted autistic traits in the offspring after controlling for ADHD behaviors and confounding variables, in males only (p = 0.04). In conclusion, this study suggests that PNMS, in the form of typical stressful life events such as divorce or a residential move, show a small but significant association with both autistic traits and ADHD behaviors independently, in offspring at age 2 years, after controlling for multiple antenatal, obstetric, postnatal, and sociodemographic covariates. This finding supports future research using epigenetic, cross-fostering, and gene-environment interaction designs to identify the causal processes underlying this association. PMID:21833278

    Full Text Available BACKGROUND: Both DSM-IV and the ICD-10 exclude diagnosis of attention deficit/hyperactivity disorder (ADHD when autism diagnostic is present. Some authors suggest, however, that autism can be associated to other comorbidity amongst which the ADHD. OBJECTIVE: To estimate prevalence of ADHD in children with autism. METHOD: Children were selected from a specialized school, all of then had previous diagnosis or diagnostic suspicion of autism. The Brazilian version of the KIDDIE-SADS PL was applied to parents for diagnostic of ADHD. DSM-IV diagnostic of autism was based on parents' interview and child observation. RESULTS: 32 children were included in the study. Results show that 53.1% of the ASD child had ADHD symptoms enough to fulfill DSM-IV diagnostic criteria, whereas 56.9% did not fulfill DSM-IV criteria for ADHD. CONCLUSION: Results suggest a high frequency of ADHD symptoms in ASD patients. Elucidating if we are facing a comorbity or an autism distinct phenotype can contribute for a more adjusted pharmacotherapy approach for these children.Tanto o DSM-IV quanto a CID-10 excluem o diagnóstico de transtorno de déficit de atenção e hiperatividade (TDAH em pacientes autistas.

    Autism is a neurodevelopmental disorder that mainly affects social interaction and communication. Evidence from behavioral and functional MRI studies supports the hypothesis that dysfunctional mechanisms involving social brain structures play a major role in autistic symptomatology. However, the investigation of anatomical abnormalities in the brain of people with autism has led to inconsistent results. We investigated whether specific brain regions, known to display functional abnormalities in autism, may exhibit mutual and peculiar patterns of covariance in their gray-matter concentrations. We analyzed structural MRI images of 32 young men affected by autistic disorder (AD) and 50 healthy controls. Controls were matched for sex, age, handedness. IQ scores were also monitored to avoid confounding. A multivariate Source-Based Morphometry (SBM) was applied for the first time on AD and controls to detect maximally independent networks of gray matter. Group comparison revealed a gray-matter source that showed differences in AD compared to controls. This network includes broad temporal regions involved in social cognition and high-level visual processing, but also motor and executive areas of the frontal lobe. Notably, we found that gray matter differences, as reflected by SBM, significantly correlated with social and behavioral deficits displayed by AD individuals and encoded via the Autism Diagnostic Observation Schedule scores. These findings provide support for current hypotheses about the neural basis of atypical social and mental states information processing in autism.

    1998-11-01

    This study explored the mechanisms underlying the hypermnesia of an autistic savant (NM) through three experiments. The first two served to assess whether absence of interference was responsible for NM's exceptional list memory. The third investigated the type of cues used in recall. Results indicated absence of retroactive interference but presence of slight proactive interference in list recall of proper names. Normal interference effects were found, however, in list recall of common nouns. Exceptional performance was also demonstrated in a missing-name task involving spatial and verbal recall cues. The findings suggest that the outstanding episodic memory presented by some savant persons with autism might be related to an abnormally high resistance to interference. PMID:10320865

    2004-04-01

    Considerable clinical and experimental evidence now supports the idea that deficiencies or imbalances in certain highly unsaturated fatty acids may contribute to a range of common developmental disorders including ADHD, dyslexia, dyspraxia and autistic spectrum disorders (ASD). Definitive evidence of a causal contribution, however, can only come from intervention studies in the form of randomised, double-blind, placebo-controlled trials. Published studies of this kind are still fairly few in number, and mainly involve the diagnostic categories of ADHD and dyslexia, although other trials involving individuals with dyspraxia or ASD are in progress. The main findings to date from such studies are reviewed and evaluated here with the primary aim of guiding future research, although given that fatty acid supplementation for these conditions is already being adopted in many quarters, it is hoped that some of the information provided may also help to inform clinical practice.

    Autism is a neurodevelopmental disorder and this disorder shows impairment in reciprocal social interactions, deficits in communication, and restrictive and repetitive patterns of behaviors and interests. The effect of music on short-term memory in the view of cell proliferation in the hippocampus was evaluated using valproic acid-induced autistic rat pups. Animal model of autism was made by subcutaneous injection of 400-mg/kg valproic acid into the rat pups on the postnatal day 14. The rat pups in the music-applied groups were exposed to the 65-dB comfortable classic music for 1 hr once a day, starting postnatal day 15 and continued until postnatal day 28. In the present results, short-term memory was deteriorated by autism induction. The numbers of 5-bromo-2'-deoxyridine (BrdU)-positive, Ki-67-positive, and doublecortin (DCX)-positive cells in the hippocampal dentate gyrus were decreased by autism induction. Brain-derived neurotrophic factor (BDNF) and tyrosine kinase B (TrkB) expressions in the hippocampus were also suppressed in the autistic rat pups. Music application alleviated short-term memory deficits with enhancing the numbers of BrdU-positive, Ki-67-positive, and DCX-positive cells in the autistic rat pups. Music application also enhanced BDNF and TrkB expressions in the autistic rat pups. The present study show that application of music enhanced hippocampal cell proliferation and alleviated short-term memory impairment through stimulating BDNF-TrkB signaling in the autistic rat pups. Music can be suggested as the therapeutic strategy to overcome the autism-induced memory deficits. PMID:27419108

    We studied the variations in the concentration of metabolites with brain region and age in autistic individuals and normal controls using multiple analysis of covariance. We examined 55 autistic individuals (2-21 years old, 47 male and eight female) and 51 normal children (3 months-15 years old, 26 boys and 25 girls). Single volumes of interest were placed in the frontal, parietal and temporal region on both sides, the brain stem and cingulate gyrus. The concentration of each metabolite was quantified by the water reference method. The concentration of N-acetylaspartate in the temporal regions (Brodmann's areas 41 and 42) in the autistic individuals were significantly lower than those in the controls (P < 0.05), but concentrations in other regions were not significantly different between the autistic individuals and controls. This suggests low density or dysfunction of neurones in Brodmann's areas 41 and 42 in autistic individual, which might be related to the disturbances of the sensory speech centre (Wernicke's area) in autism.

  6. What affects social attention? Social presence, eye contact and autistic traits.

    Directory of Open Access Journals (Sweden)

    Megan Freeth

    Full Text Available Social understanding is facilitated by effectively attending to other people and the subtle social cues they generate. In order to more fully appreciate the nature of social attention and what drives people to attend to social aspects of the world, one must investigate the factors that influence social attention. This is especially important when attempting to create models of disordered social attention, e.g. a model of social attention in autism. Here we analysed participants' viewing behaviour during one-to-one social interactions with an experimenter. Interactions were conducted either live or via video (social presence manipulation. The participant was asked and then required to answer questions. Experimenter eye-contact was either direct or averted. Additionally, the influence of participant self-reported autistic traits was also investigated. We found that regardless of whether the interaction was conducted live or via a video, participants frequently looked at the experimenter's face, and they did this more often when being asked a question than when answering. Critical differences in social attention between the live and video interactions were also observed. Modifications of experimenter eye contact influenced participants' eye movements in the live interaction only; and increased autistic traits were associated with less looking at the experimenter for video interactions only. We conclude that analysing patterns of eye-movements in response to strictly controlled video stimuli and natural real-world stimuli furthers the field's understanding of the factors that influence social attention.

  7. Individual differences in autistic trait load in the general population predict visual working memory performance.

    Prior studies have reported instances of both intact and impaired working memory (WM) performance in people with autism spectrum disorder (ASD). In order to investigate the relation between autistic traits that extend into the normal population and WM, 104 normal college-aged students who varied in their levels of autistic traits were tested. The loading of ASD-associated traits in the normal population leads to differing predictions about WM performance. ASD traits related to a local processing style (or "attention to detail") might enhance WM while ASD-associated traits related to difficulty switching attention and reorienting focus (or "social interaction") might impair WM performance. To assess these predictions, participants filled out the Autism Spectrum Quotient (AQ) and performed a working memory task with both visual and verbal variants. AQ scores were then broken into "attention to detail" and "social interaction" factors, as proposed by Hoekstra and colleagues. The results showed that AQ scores did not predict verbal WM performance but they did predict visual WM performance. The social interaction and attention to detail factors of the AQ had opposing relationships with visual WM performance: A higher level of social difficulty was associated with significantly poorer visual WM performance while a higher level of attention to detail was associated with enhanced visual WM performance. Further investigation of the relation between AQ and WM using the original five-factor model proposed by Baron-Cohen and colleagues (2001) revealed an association between impoverished imagination and visual WM overall.

    Full Text Available The aim of this study is to assess whether the dental caries experience is higher in children with an autistic disorder (AD than in normal children. Three schools for autistic children and three standard elementary schools in Istanbul, Turkey, were included in a cross-sectional study. Subjects were orally examined. Socio-demographic information and data about their oral care habits were obtained from their parents from records. Sixty-two children with AD and 301 children without AD were examined. Their ages varied between 6 and 12 years. Children with AD compared to those without AD had lower experience of caries. Logistic regression analysis of DMFT showed that the dental status was positively affected in younger children (OR = 15.57; 95% CI 7.62, 31.80, children from families with high income (OR = 5.42; 95% CI 2.31, 12.75, children brushing teeth regularly (OR = 2.01, 95% CI 1.10, 3.68, children consuming less sugar (OR = 5.01; 95% CI 2.57, 9.76 and in those with AD (OR=3.99; 95% CI 1.56, 10.19. Children with AD had better caries status than children without AD at younger ages.

  9. Proper name hypermnesia in an autistic subject.

    The case study of an autistic "savant" subject with person names hypermnesia is presented. NM's performance in memorizing person names is compared to that of normal controls, IQ-matched controls, and one overtrained control. The data show a selective hypermnesia for both the free recall of person names and the recognition of faces. Recall of common names and of biographical informations linked to faces is unremarkable. NM's hypermnesia is restricted to list learning as low performance is observed in face-name learning tasks. A comparison of the data with that of the overtrained control indicates that training is not responsible for NM's pattern of results. These findings, when combined with previous results involving proper names, demonstrate a double dissociation between proper names and other types of semantic and referential information. However, aspects of NM's performance pattern are more compatible with a network model of proper names than with a sequential model. We propose that the contextual regularity of proper names in ecological situations can be responsible for their high memorization by NM. PMID:8798332

  11. Assessing musical skills in autistic children who are not savants.

    2009-05-27

    Descriptions of autistic musical savants suggest that they possess extraordinary skills within the domain. However, until recently little was known about the musical skills and potential of individuals with autism who are not savants. The results from these more recent studies investigating music perception, cognition and learning in musically untrained children with autism have revealed a pattern of abilities that are either enhanced or spared. For example, increased sensitivity to musical pitch and timbre is frequently observed, and studies investigating perception of musical structure and emotions have consistently failed to reveal deficits in autism. While the phenomenon of the savant syndrome is of considerable theoretical interest, it may have led to an under-consideration of the potential talents and skills of that vast majority of autistic individuals, who do not meet savant criteria. Data from empirical studies show that many autistic children possess musical potential that can and should be developed. PMID:19528029

    In a population-based study, we examined the associations of maternal plasma folate concentrations at 13 weeks of gestation and prenatal folic acid supplement use with autistic traits in the offspring at the age of six years. Parent-reported autistic traits were assessed using the Social Responsiveness Scale short form. Maternal folate was not associated with autistic traits in the offspring. In contrast, prenatal folic acid use was associated with less child autistic traits. Future research should focus on the timing of the potential effect of prenatal folate on the development of autistic traits in combination with clinical diagnosis of autism in the offspring.

    We evaluated phonological and visuospatial working memory (WM) in autism spectrum disorders. Autistic children and typically developing children were compared. We used WM tasks that measured phonological and visuospatial WM up to the capacity limit of each children. Overall measures of WM did not show differences between autistic children and control children. However, when the recall of children was examined in detail, autistic children showed reduced phonological WM compared with control children. Moreover, phonological and visuospatial WM did not increase with the age of autistic children while a development of phonological and visuospatial WM with age was found in control children. The pattern of results is discussed in terms of previous studies about WM and autism. PMID:27314268

    Physiological, cognitive, and emotional factors were examined throughout the treatment of a psychotic child. Heart rate, latency and accuracy in task performance, behavioral indices of stress (e.g., muscular tension, facial expression), and frequency of autistic mannerisms were measured concurrently. Both contemporaneous relationships and patterns of change suggested that autistic behaviors were organized and psychologically meaningful. Self-stimulation, conflict, and negativism (deliberate erroneous performance) occurred predictably, were intimately related, and were associated with specific patterns of heart-rate change. The changing function of self-stimulation across treatment and the centrality of negativism in this child's disturbance were discussed. PMID:24198177

    2015-08-01

    This paper looks at the association between gender dysphoria (GD), scores on the Social Responsiveness Scale (SRS), and reported diagnoses of autism spectrum disorder (ASD). Parents of 166 young people presenting with GD (Mean age = 14.26, SD = 2.68) completed the SRS. Information concerning an ASD diagnosis was also extracted from the patient files. 45.8% fell within the normal range on the SRS and of those 2.8% had an ASD diagnosis. 27.1% fell within the mild/moderate range and of those 15.6% had an ASD diagnosis and 6.7% an ASD query. 27.1% fell within the severe range and of those 24.4% had an ASD diagnosis and 26.7% an ASD query. No difference was found in autistic features between the natal females and males. PMID:25772537

    Full Text Available Introduction: In early typical language development, children understand words before they are able to use them in speech. Children with autism spectrum disorders (ASD generally show impairments in both the comprehension and the production of language. However, the relative degree of delay or impairment in each of these sub-domains may also be atypical and remains less well-understood. Materials and Methods: This study was a causal-comparative that including 30 children ( 15 girls and 15 boys with ASD,   who elected by random sampling. Data analysis was done using SPSS-16 and T-student test. Results: Results of t- tests showed significant differences between the two groups, autistic and normal children in the expressive language skill, cognitive and received language skill (P

  18. Gaze recognition in high-functioning autistic patients. Evidence from functional MRI

    International Nuclear Information System (INIS)

    We examined whether patients with high-functioning autistic disorder (AD) would exhibit abnormal activation in brain regions implicated in the functioning of theory of mind (TOM) during gaze recognition. We investigated brain activity during gaze recognition in 5 patients with high-functioning AD and 9 normal subjects, using functional magnetic resonance imaging. On the gaze task, more activation was found in the left middle frontal gyrus, the right intraparietal sulcus, and the precentral and inferior parietal gyri bilaterally in controls than in AD patients, whereas the patient group showed more powerful signal changes in the left superior temporal gyrus, the right insula, and the right medial frontal gyrus. These results suggest that high-functioning AD patients have functional abnormalities not only in TOM-related brain regions, but also in widely distributed brain regions that are not normally activated upon the processing of information from another person's gaze.

    Full Text Available Objectives: The purpose of this study is to achieve a vision for autistic children and their parents aimed at generating interest in ideas such as “Sanitas Per Aquam” (SPA, massage and music therapy, which has begun to have widespread use and to attract attention. Methods: This cross-sectional, descriptive study was carried out with autistic children and their parents from February to April 2015 in Muğla, Turkey. The study was began by interviewing experts in the field and by developing a suitable assessment questionnaire. In order to direct the flow of conversation between the researchers and the autisitc children and their parents, the researchers conducted semi-structured face to face interviews in a form that had been determined by using reports in the literature and the opinions of experts in the field. Results: Forty two boys (84% and eight girls (16% with autism participated in our study. Children in the 0 ─ 7 age group spent long time in the bathroom (P = 0.001. Boys liked to be hugged more than girls (P = 0.01. Children ages 0 ─ 7 years liked bright lighting while those 15 years of age and older liked gloomy lighting (P = 0.009. Except for these statistically significant sex- and age-related differences, no other statistically significant differences were noted in the parameters of this study. Although the result was not statistically significant, more children with mild autism disorder obeyed commands like inhale or exhale (P = 0.051. Conclusion: Treatment for autism spectrum disorders is not yet fully possible, so many studies are being done to alleviate some symptoms and to improve the quality of life for individuals with autism and their families. As a result of our study, whether touching the areas the children want touched and listening to their favorite music are required to stimulate the brain remain as questions in our minds.

However, it is rarely used to distinguish the functional level of children with autistic spectrum disorder (ASD). This study aims to explore the interplay. The subjects were 152 children diagnosed by hospital as having ASD, 121 boys, 31 girls, ranging from 3 years and 2 months old to 14 years and 5 months old, with a mean age of 8 years and 8 months. Based on IQ scores, parent questionnaires, and play observations, tbe subjects were grouped into four function levels: low, middle-low, middle-high, and high. During the study, children were told to play freely in the sandbox with toys and create something. Still and video cameras were used to record the play processes and products and then recordings were analyzed both quantitatively and qualitatively. Three hierarchical function indexes, "Experience and Adaption", "Recognition and Selection", and "Strategy and Operation" with three variables in each index, were used to quantitatively analyze the process and products of children's sand play. Function indexes are found to be consistent in all three levels.

    Autism spectrum disorders (ASDs) are neurodevelopmental disorders characterized by impaired social interaction, isolated areas of interest, and insistence on sameness. Mutations in Phosphatase and tensin homolog missing on chromosome 10 (PTEN) have been reported in individuals with ASDs. Recent evidence highlights a crucial role of the cerebellum in the etiopathogenesis of ASDs. In the present study we analyzed the specific contribution of cerebellar Purkinje cell (PC) PTEN loss to these disorders. Using the Cre-loxP recombination system, we generated conditional knockout mice in which PTEN inactivation was induced specifically in PCs. We investigated PC morphology and physiology as well as sociability, repetitive behavior, motor learning, and cognitive inflexibility of adult PC PTEN-mutant mice. Loss of PTEN in PCs results in autistic-like traits, including impaired sociability, repetitive behavior and deficits in motor learning. Mutant PCs appear hypertrophic and show structural abnormalities in dendrites and axons, decreased excitability, disrupted parallel fiber and climbing fiber synapses and late-onset cell death. Our results unveil new roles of PTEN in PC function and provide the first evidence of a link between the loss of PTEN in PCs and the genesis of ASD-like traits. PMID:26538449

    2016-02-25

    Because autism spectrum disorders are neurodevelopmental disorders and patients typically display symptoms before the age of three, one of the key questions in autism research is whether the pathology is reversible in adults. Here we investigate the developmental requirement of Shank3 in mice, a prominent monogenic autism gene that is estimated to contribute to approximately 1% of all autism spectrum disorder cases. SHANK3 is a postsynaptic scaffold protein that regulates synaptic development, function and plasticity by orchestrating the assembly of postsynaptic density macromolecular signalling complex. Disruptions of the Shank3 gene in mouse models have resulted in synaptic defects and autistic-like behaviours including anxiety, social interaction deficits, and repetitive behaviour. We generated a novel Shank3 conditional knock-in mouse model, and show that re-expression of the Shank3 gene in adult mice led to improvements in synaptic protein composition, spine density and neural function in the striatum. We also provide behavioural evidence that certain behavioural abnormalities including social interaction deficit and repetitive grooming behaviour could be rescued, while anxiety and motor coordination deficit could not be recovered in adulthood. Together, these results reveal the profound effect of post-developmental activation of Shank3 expression on neural function, and demonstrate a certain degree of continued plasticity in the adult diseased brain.

  2. The level and nature of autistic intelligence II: what about Asperger syndrome?

    Directory of Open Access Journals (Sweden)

    Isabelle Soulières

    Full Text Available A distinctively uneven profile of intelligence is a feature of the autistic spectrum. Within the spectrum, Asperger individuals differ from autistics in their early speech development and in being less likely to be characterized by visuospatial peaks. While different specific strengths characterize different autistic spectrum subgroups, all such peaks of ability have been interpreted as deficits: isolated, aberrant, and irreconcilable with real human intelligence. This view has recently been challenged by findings of autistic strengths in performance on Raven's Progressive Matrices (RPM, an important marker of general and fluid intelligence. We investigated whether these findings extend to Asperger syndrome, an autistic spectrum subgroup characterized by verbal peaks of ability, and whether the cognitive mechanisms underlying autistic and Asperger RPM performance differ. Thirty-two Asperger adults displayed a significant advantage on RPM over Wechsler Full-Scale and Performance scores relative to their typical controls, while in 25 Asperger children an RPM advantage was found over Wechsler Performance scores only. As previously found with autistics, Asperger children and adults achieved RPM scores at a level reflecting their Wechsler peaks of ability. Therefore, strengths in RPM performance span the autistic spectrum and imply a common mechanism advantageously applied to different facets of cognition. Autistic spectrum intelligence is atypical, but also genuine, general, and underestimated.

    2003-01-01

    The phenomenon of echolalia in autistic language is well documented. Whilst much early research dismissed echolalia as merely an indicator of cognitive limitation, later work identified particular discourse functions of echolalic utterances. The work reported here extends the study of the interactional significance of echolalia to formulaic utterances. Audio and video recordings of conversations between the first author and two research participants were transcribed and analysed according to a Conversation Analysis framework and a multi-layered linguistic framework. Formulaic language was found to have predictable interactional significance within the language of an individual with autism, and the generic phenomenon of formulaicity in company with predictable discourse function was seen to hold across the research participants, regardless of cognitive ability. The implications of formulaicity in autistic language for acquisition and processing mechanisms are discussed. PMID:12945605

    Full Text Available Research has proposed that autistic-like traits in the general population lie on a continuum, with clinical Autism Spectrum Disorder (ASD representing the extreme end of this distribution. Inherent in this proposal is that biological mechanisms associated with clinical ASD may also underpin variation in autistic-like traits within the general population. A genome-wide association study using 2,462,046 single nucleotide polymorphisms (SNPs was undertaken for ASD in 965 individuals from the Western Australian Pregnancy Cohort (Raine Study. No SNP associations reached genome-wide significance (p < 5.0 x 10-8. However, investigations into nominal observed SNP associations (p < 1.0 x 10-5 add support to two positional candidate genes previously implicated in ASD aetiology, PRKCB1 and CBLN1.The rs198198 SNP (p = 9.587 x 10-6, is located within an intron of the protein kinase C, beta 1 (PRKCB1 gene on chromosome 16p11. The PRKCB1 gene has been previously reported in linkage and association studies for ASD, and its mRNA expression has been shown to be significantly down regulated in ASD cases compared with controls. The rs16946931 SNP (p = 1.78 x 10-6 is located in a region flanking the Cerebellin 1 (CBLN1 gene on chromosome 16q12.1. The CBLN1 gene is involved with synaptogenesis and is part of a gene family previously implicated in ASD. This GWA study is only the second to examine SNPs associated with autistic-like traits in the general population, and provides evidence to support roles for the PRKCB1 and CBLN1 genes in risk of clinical ASD.

    There is accumulating evidence that autistic traits (AT) are on a continuum in the general population, with clinical autism representing the extreme end of a quantitative distribution. While the nature and severity of symptoms in clinical autism are known to persist over time, no study has examined the long-term stability of AT among typically developing toddlers. The current investigation measured AT in 360 males and 400 males from the general population close to two decades apart, using the...

    The aim of the present study was to describe the prevalence and associated factors of pervasive developmental disorders (PDD), including autistic disorder and PDD not otherwise specified (NOS), in a clinical sample of 126 children and adolescents (75 males, 51 females; age range 4-18y, mean 8y 8mo, SD 3y 8mo) with tetraplegic, hemiplegic, diplegic, dyskinetic, or mixed types of cerebral palsy (CP); 28% could not crawl or walk even with support, 29% could move with support, and 43% walked independently. Participants were examined for PDD in two stages. In the first stage, probable participants were determined by direct observation, Autism Behavior Checklist score, and medical reports. In the second stage, those with 'probable' symptoms underwent psychiatric examination and their autistic symptoms were scored on the Childhood Autism Rating Scale. The final diagnosis of autistic disorder or PDD-NOS was given according to DSM-IV criteria. Fourteen (11%) and five (4%) of the participants met the criteria for autistic disorder and PDD-NOS respectively. Children with CP and PDD differed from those without PDD in terms of type of CP (p=0.02), presence of epilepsy (plearning disability, and low level of speech. The findings corroborate the notion that CP is a complex disorder, often associated with additional impairments. PDD is not rare in CP and should be considered in patients with comorbid conditions such as epilepsy, learning disability, and language delay and in the presence of tetraplegic, mixed, and hemiplegic CP types.

  13. Examining the Genetic and Environmental Associations between Autistic Social and Communication Deficits and Psychopathic Callous-Unemotional Traits.

    Full Text Available Difficulties in appropriate social interaction are characteristic of both children with autism spectrum disorders and children with callous-unemotional traits (who are at risk of developing psychopathy. Extant experimental studies suggest that the nature of atypical social cognition that characterises these two profiles is not identical. However, 'empathizing' difficulties have been hypothesised for both groups, raising questions about the degree of aetiological separation between social impairments that characterize each disorder. This study explored the relative contribution of independent vs. shared aetiological influences to social and communication impairments associated with autistic traits and callous-unemotional traits, indexed by parent-report in a population-based cohort of twins.Participants were over 5,000 twin pairs from a UK cohort (the Twins Early Development Study; TEDS, assessed for callous-unemotional traits at 7 years and autistic social and communication impairments at 8 years. Multivariate model-fitting was used to explore the relative contribution of independent vs. overlapping genetic/environmental influences on these traits.Both social and communication impairments and callous-unemotional traits were highly heritable, although the genetic and environmental influences accounting for individual differences on each domain were predominantly independent.Extant evidence from experimental and neuro-imaging studies has suggested that, despite some superficially overlapping behaviours, the social difficulties seen in children with autism spectrum disorders and callous-unemotional traits are largely distinct. The current study is the first to demonstrate considerable aetiological independence of the social interaction difficulties seen in children with autism spectrum disorders and those with callous-unemotional traits.

    ω-3 and ω-6 polyunsaturated fatty acids are important for brain function and development. We examined whether maternal polyunsaturated fatty acid status during pregnancy affects risk of autistic traits in childhood. Within the Generation R cohort, we measured maternal plasma polyunsaturated fatty acid concentrations and the ω-3:ω-6 ratio in midpregnancy (Rotterdam, the Netherlands, 2001-2005). Child autistic traits at 6 years were assessed by using the Social Responsiveness Scale short form in 4,624 children. A lower maternal ω-3:ω-6 ratio during pregnancy was associated with more autistic traits in the offspring (β = -0.008, 95% confidence interval: -0.016, -0.001). In particular, a higher total ω-6 and linoleic acid status were associated with more autistic traits (all P's < 0.05). Associations were independent of child intelligence, suggesting that the fatty acid distribution specifically affects the development of autistic traits in addition to general neurodevelopment. Maternal plasma ω-3 status was not associated with child autistic traits and, consistently, neither was prenatal dietary fish intake. Our study shows that a lower prenatal ω-3:ω-6 ratio is associated with more child autistic traits, which is largely accounted for by higher ω-6 instead of lower ω-3 status. These results suggest a biological pathway between maternal fatty acid intake during pregnancy and autistic traits in the offspring. PMID:27052119

    Autism is a neurodevelopment disorder. One percent worldwide population suffers with autism and males suffer more than females. Microglia plays an important role in neurodevelopment, neuropsychiatric and neurodegenerative disorders. The present study has been designed to investigate the role of minocycline in prenatal valproic acid induced autism in rats. Animals with prenatal valproic acid have reduced social interaction (three chamber social behaviour apparatus), spontaneous alteration (Y-Maze), exploratory activity (Hole board test), intestinal motility, serotonin levels (both in prefrontal cortex and ileum) and prefrontal cortex mitochondrial complex activity (complexes I, II, IV). Furthermore, prenatal valproic acid treated animals have shown an increase in locomotion (actophotometer), anxiety (elevated plus maze), brain oxidative stress (thiobarbituric acid reactive species, glutathione, catalase), nitrosative stress (nitrite/nitrate), inflammation (both in brain and ileum myeloperoxidase activity), calcium and blood brain barrier permeability. Treatment with minocycline significantly attenuated prenatal valproic acid induced reduction in social interaction, spontaneous alteration, exploratory activity intestinal motility, serotonin levels and prefrontal cortex mitochondrial complex activity. Furthermore, minocycline has also attenuated prenatal valproic acid induced increase in locomotion, anxiety, brain oxidative and nitrosative stress, inflammation, calcium and blood brain barrier permeability. Thus, it may be concluded that prenatal valproic acid has induced autistic behaviour, biochemistry and blood brain barrier impairment in animals, which were significantly attenuated by minocycline. Minocycline should be explored further for its therapeutic benefits in autism. PMID:26551768

  8. Neurexin Dysfunction in Adult Neurons Results in Autistic-like Behavior in Mice

    Directory of Open Access Journals (Sweden)

    Luis G. Rabaneda

    2014-07-01

    Full Text Available Autism spectrum disorders (ASDs comprise a group of clinical phenotypes characterized by repetitive behavior and social and communication deficits. Autism is generally viewed as a neurodevelopmental disorder where insults during embryonic or early postnatal periods result in aberrant wiring and function of neuronal circuits. Neurexins are synaptic proteins associated with autism. Here, we generated transgenic βNrx1ΔC mice in which neurexin function is selectively impaired during late postnatal stages. Whole-cell recordings in cortical neurons show an impairment of glutamatergic synaptic transmission in the βNrx1ΔC mice. Importantly, mutant mice exhibit autism-related symptoms, such as increased self-grooming, deficits in social interactions, and altered interaction for nonsocial olfactory cues. The autistic-like phenotype of βNrx1ΔC mice can be reversed after removing the mutant protein in aged animals. The defects resulting from disruption of neurexin function after the completion of embryonic and early postnatal development suggest that functional impairment of mature circuits can trigger autism-related phenotypes.

    This work demonstrates data of multiple regression analysis between nine biomarkers related to glutamate excitotoxicity and impaired detoxification as two mechanisms recently recorded as autism phenotypes. The presented data was obtained by measuring a panel of markers in 20 autistic patients aged 3-15 years and 20 age and gender matching healthy controls. Levels of GSH, glutathione status (GSH/GSSG), glutathione reductase (GR), glutathione-s-transferase (GST), thioredoxin (Trx), thioredoxin reductase (TrxR) and peroxidoxins (Prxs I and III), glutamate, glutamine, glutamate/glutamine ratio glutamate dehydrogenase (GDH) in plasma and mercury (Hg) in red blood cells were determined in both groups. In Multiple regression analysis, R (2) values which describe the proportion or percentage of variance in the dependent variable attributed to the variance in the independent variables together were calculated. Moreover, β coefficients values which show the direction either positive or negative and the contribution of the independent variable relative to the other independent variables in explaining the variation of the dependent variable were determined. A panel of inter-related markers was recorded. This paper contains data related to and supporting research articles currently published entitled "Mechanism of nitrogen metabolism-related parameters and enzyme activities in the pathophysiology of autism" [1], "Novel metabolic biomarkers related to sulfur-dependent detoxification pathways in autistic patients of Saudi Arabia [2], and "A key role for an impaired detoxification mechanism in the etiology and severity of autism spectrum disorders" [3].

    Full Text Available Abstract Backgrounds Autism is a developmental disorder characterized by social and emotional deficits, language impairments and stereotyped behaviors that manifest in early postnatal life. This study aims to compare the relative concentrations of essential fatty acids (Linoleic and α- linolenic, their long chain polyunsaturated fatty acids and phospholipids in plasma of autistic patients from Saudi Arabia with age-matching controls. Methods 25 autistic children aged 3-15 years and 16 healthy children as control group were included in this study. Relative concentration of essential fatty acids/long chain polyunsaturated fatty acids and omega-3/omega-6 fatty acid series together with phosphatidylethanolamine, phosphatidylserine and phosphatidylcholine were measured in plasma of both groups. Results Remarkable alteration of essential fatty acids/long chain polyunsaturated fatty acids, omeg-3/omega-6 and significant lower levels of phospholipids were reported. Reciever Operating characteristics (ROC analysis of the measured parameters revealed a satisfactory level of sensitivity and specificity. Conclusion Essential fatty acids/long chain polyunsaturated fatty acids and omeg-3/omega-6 ratios, phosphatidylethanolamine, phosphatidylserine and phosphatidylcholine could be used as potential biomarkers that point to specific mechanisms in the development of autism and may help tailor treatment or prevention strategies.

  11. Sera from children with autism induce autistic features which can be rescued with a CNTF small peptide mimetic in rats.

    Directory of Open Access Journals (Sweden)

    Syed Faraz Kazim

    Full Text Available Autism is a neurodevelopmental disorder characterized clinically by impairments in social interaction and verbal and non-verbal communication skills as well as restricted interests and repetitive behavior. It has been hypothesized that altered brain environment including an imbalance in neurotrophic support during early development contributes to the pathophysiology of autism. Here we report that sera from children with autism which exhibited abnormal levels of various neurotrophic factors induced cell death and oxidative stress in mouse primary cultured cortical neurons. The effects of sera from autistic children were rescued by pre-treatment with a ciliary neurotrophic factor (CNTF small peptide mimetic, Peptide 6 (P6, which was previously shown to exert its neuroprotective effect by modulating CNTF/JAK/STAT pathway and LIF signaling and by enhancing brain derived neurotrophic factor (BDNF expression. Similar neurotoxic effects and neuroinflammation were observed in young Wistar rats injected intracerebroventricularly with autism sera within hours after birth. The autism sera injected rats demonstrated developmental delay and deficits in social communication, interaction, and novelty. Both the neurobiological changes and the behavioral autistic phenotype were ameliorated by P6 treatment. These findings implicate the involvement of neurotrophic imbalance during early brain development in the pathophysiology of autism and a proof of principle of P6 as a potential therapeutic strategy for autism.

  12. Gene expression profiling of lymphoblasts from autistic and nonaffected sib pairs: altered pathways in neuronal development and steroid biosynthesis.

    Directory of Open Access Journals (Sweden)

    Valerie W Hu

    Full Text Available Despite the identification of numerous autism susceptibility genes, the pathobiology of autism remains unknown. The present "case-control" study takes a global approach to understanding the molecular basis of autism spectrum disorders based upon large-scale gene expression profiling. DNA microarray analyses were conducted on lymphoblastoid cell lines from over 20 sib pairs in which one sibling had a diagnosis of autism and the other was not affected in order to identify biochemical and signaling pathways which are differentially regulated in cells from autistic and nonautistic siblings. Bioinformatics and gene ontological analyses of the data implicate genes which are involved in nervous system development, inflammation, and cytoskeletal organization, in addition to genes which may be relevant to gastrointestinal or other physiological symptoms often associated with autism. Moreover, the data further suggests that these processes may be modulated by cholesterol/steroid metabolism, especially at the level of androgenic hormones. Elevation of male hormones, in turn, has been suggested as a possible factor influencing susceptibility to autism, which affects approximately 4 times as many males as females. Preliminary metabolic profiling of steroid hormones in lymphoblastoid cell lines from several pairs of siblings reveals higher levels of testosterone in the autistic sibling, which is consistent with the increased expression of two genes involved in the steroidogenesis pathway. Global gene expression profiling of cultured cells from ASD probands thus serves as a window to underlying metabolic and signaling deficits that may be relevant to the pathobiology of autism.

    Behaviors associated with autism spectrum disorder (ASD) have been suggested to be considered as quantitative traits. This study investigated the structural and functional correlates of autistic traits measured using the Social Responsiveness Scale (SRS) in neurotypical adolescents. Twenty-six neurotypical male adolescents (12-18 years old) were recruited for this study and underwent structural and resting functional magnetic resonance image scanning, and intelligence quotient and SRS evaluations. We used the automated surface-based method (FreeSurfer) to measure cortical thickness and seed-based functional connectivity (FC) analysis to derive the FC map of the dorsal anterior cingulate (dACC). Brain-wise regression analyses of cortical thickness and FC maps on SRS scores were performed using a general linear model. The results indicated that higher autistic trait ratings of total SRS scores were associated with a thinner cortex in the left insula, right insula, and right superior temporal gyrus. Furthermore, we observed that only higher scores of social awareness were correlated with increased FC between the dACC and right superior temporal gyrus and decreased FC between the dACC and right putamen and thalamus. These results indicated that a quantitative trait in social cognition is associated with structural and connectivity variations linked to ASD patients.

    This research investigates the paradox of creativity in autism. That is, whether people with subclinical autistic traits have cognitive styles conducive to creativity or whether they are disadvantaged by the implied cognitive and behavioural rigidity of the autism phenotype. The relationship between divergent thinking (a cognitive component of creativity), perception of ambiguous figures, and self-reported autistic traits was evaluated in 312 individuals in a non-clinical sample. High levels of autistic traits were significantly associated with lower fluency scores on the divergent thinking tasks. However autistic traits were associated with high numbers of unusual responses on the divergent thinking tasks. Generation of novel ideas is a prerequisite for creative problem solving and may be an adaptive advantage associated with autistic traits. PMID:26272675

    To determine involvements of the brain stem and/or cerebellum in autism, we compared midsagittal magnetic resonance images of the brains of high functioning autistic children with those of normal controls. We found that the midbrain and medulla oblongata were significantly smaller in these autistic children than in the control children. The pons area did not differ between the two groups, nor was there any difference in the cerebellar vermis area. The ratio of the brain stem and cerebellum to the posterior fossa area did not differ significantly between the high functioning autistic and the control children. The development of the cerebellar vermis area was delayed in autistic children as compared with that in the control children. Thus, it was suggested that significant anatomical changes in the midbrain and medulla oblongata existed in the autistic children. (author).

    Bölte, Sven; Poustka, Fritz; Constantino, John N

    2008-12-01

    The Social Responsiveness Scale (SRS) is a quantitative measure of autistic traits in 4- to 18-year-olds, which has been used in behavior-genetic, epidemiological and intervention studies. The US standardization demonstrated a single-factor structure and good to excellent psychometric properties. The cross-cultural validity of the German adaptation of the parent-report SRS in a sample of N=1,436 children and adolescents: 838 typically developing and 527 clinical participants (160 with autism spectrum disorders (ASDs)) was examined. Internal consistency (0.91-0.97), test-retest reliability (0.84-0.97), interrater reliability (0.76 and 0.95) and convergent validity with the Autism Diagnostic Observation Schedule as well as the Autism Diagnostic Interview-Revised and Social Communication Questionnaire (0.35-0.58) were satisfactory to good. The SRS total score discriminated between ASD and other mental disorders. SRS scores proved to be sufficiently independent of general psychopathology. Principal component analyses yielded single-factor solutions for the normative and clinical subsamples. In addition, construct validity was ensured by consistent correlations with the Vineland Adaptive Behavior Scales, the Child Behavior Checklist and the Junior Temperament and Character Inventory. Normative SRS total scores for girls and boys as well as values for ASD were lower in the German sample, while scores for conduct disorder and attention deficit hyperactivity/conduct disorder combined were higher. Generally, cross-cultural validity of the SRS seems to be sufficiently assured for a large European sample. However, some discrepancies regarding SRS normative and clinical raw score distributions, reliability and validity findings are critically discussed. PMID:19360690

    Two autistic children were treated for specific fears. A three-component participant modeling procedure was implemented within a multiple baseline design across subjects. Children were exposed gradually to fearful situations, with mothers serving as therapists and reinforcers. Dependent measures were (a) number of approach steps completed, (b) frequency of verbalizations and vocalizations of fear, and (c) overall appearance of fear. Following treatment, the children functioned effectively in previously fearful situations without verbalizations or appearance of fear. Five-month and 1-year follow-up assessments with 1 child showed maintenance of treatment effects. PMID:2249973

    Developmental coordination disorder (DCD) is a common motor problem affecting—even in rather severe form—several percent of school age children. In the past, DCD has usually been called ‘clumsy child syndrome’ or ‘non-cerebralpalsy motor-perception dysfunction’. This disorder is more common in boys than in girls and is very often associated with psychopathology, particularly with attention-deficit/hyperactivity disorder (ADHD) and autism spectrum disorders/ autistic-type problems.

  9. The Autistic Phenotype Exhibits a Remarkably Localized Modification of Brain Protein by Products of Free Radical-Induced Lipid Oxidation

    Directory of Open Access Journals (Sweden)

    Teresa A. Evans

    2008-01-01

    Full Text Available Oxidative damage has been documented in the peripheral tissues of autism patients. In this study, we sought evidence of oxidative injury in autistic brain. Carboxyethyl pyrrole (CEP and iso[4]levuglandin (iso[4]LGE2-protein adducts, that are uniquely generated through peroxidation of docosahexaenoate and arachidonate-containing lipids respectively, and heme oxygenase-1 were detected immunocytochemically in cortical brain tissues and by ELISA in blood plasma. Significant immunoreactivity toward all three of these markers of oxidative damage in the white matter and often extending well into the grey matter of axons was found in every case of autism examined. This striking threadlike pattern appears to be a hallmark of the autistic brain as it was not seen in any control brain, young or aged, used as controls for the oxidative assays. Western blot and immunoprecipitation analysis confirmed neurofilament heavy chain to be a major target of CEP-modification. In contrast, in plasma from 27 autism spectrum disorder patients and 11 age-matched healthy controls we found similar levels of plasma CEP (124.5 ± 57.9 versus 110.4 ± 30.3 pmol/mL, iso[4]LGE2 protein adducts (16.7 ± 5.8 versus 13.4 ± 3.4 nmol/mL, anti-CEP (1.2 ± 0.7 versus 1.2 ± 0.3 and anti-iso[4]LGE2 autoantibody titre (1.3 ± 1.6 versus 1.0 ± 0.9, and no differences between the ratio of NO2Tyr/Tyr (7.81 E-06 ± 3.29 E-06 versus 7.87 E-06 ± 1.62 E-06. These findings provide the first direct evidence of increased oxidative stress in the autistic brain. It seems likely that oxidative injury of proteins in the brain would be associated with neurological abnormalities and provide a cellular basis at the root of autism spectrum disorders.

  11. Genetic-background modulation of core and variable autistic-like symptoms in Fmr1 knock-out mice.

    Directory of Open Access Journals (Sweden)

    Susanna Pietropaolo

    Full Text Available BACKGROUND: No animal models of autism spectrum disorders (ASD with good construct validity are currently available; using genetic models of pathologies characterized by ASD-like deficits, but with known causes, may be therefore a promising strategy. The Fmr1-KO mouse is an example of this approach, modeling Fragile X syndrome, a well-known genetic disorder presenting ASD symptoms. The Fmr1-KO is available on different genetic backgrounds (FVB versus C57BL/6, which may explain some of the conflicting results that have been obtained with these mutants up till now. METHODS: Fmr1 KO and their wild-type littermates on both the FVB and C57BL/6 genetic backgrounds were examined on a battery of tests modeling the clinical symptoms of ASD, including the triad of core symptoms (alterations in social interaction and communication, presence of repetitive behaviors, as well as the secondary symptoms (disturbances in sensori-motor reactivity and in circadian patterns of activity, epileptic events. RESULTS: Fmr1-KO mice displayed autistic-like core symptoms of altered social interaction and occurrence of repetitive behaviors with additional hyperactivity. The genetic background modulated the effects of the Fmr1 deletion and it appears that the C57BL/6 background may be more suitable for further research on core autistic-like symptoms. CONCLUSIONS: The Fmr1-mouse line does not recapitulate all of the main core and secondary ASD symptoms, but still can be useful to elucidate the neurobiological mechanisms underlying specific ASD-like endophenotypes.

    Ben-Reuven, Lihi; Reiner, Orly

    2016-06-01

    The opportunity to model autism spectrum disorders (ASD) through generation of patient-derived induced pluripotent stem cells (iPSCs) is currently an emerging topic. Wide-scale research of altered brain circuits in syndromic ASD, including Rett Syndrome, Fragile X Syndrome, Angelman's Syndrome and sporadic Schizophrenia, was made possible through animal models. However, possibly due to species differences, and to the possible contribution of epigenetics in the pathophysiology of these diseases, animal models fail to recapitulate many aspects of ASD. With the advent of iPSCs technology, 3D cultures of patient-derived cells are being used to study complex neuronal phenotypes, including both syndromic and nonsyndromic ASD. Here, we review recent advances in using iPSCs to study various aspects of the ASD neuropathology, with emphasis on the efforts to create in vitro model systems for syndromic and nonsyndromic ASD. We summarize the main cellular activity phenotypes and aberrant genetic interaction networks that were found in iPSC-derived neurons of syndromic and nonsyndromic autistic patients. PMID:27111774

  14. Vision Therapy for the Autistic Patient: A Literature Review and Case Report

    Directory of Open Access Journals (Sweden)

    Michael Au, OD

    2014-10-01

    Full Text Available Background: The heightened awareness of autism spectrum disorder (ASD has propelled concern for proper care into a significant public health issue. Vision deficits, including visual processing and integration, may contribute to the anxiety and uneasiness that these individuals frequently experience. Additionally, these deficits often translate into considerable hindrances to classroom success. This paper addresses a sampling of vision-based behaviors in ASD including visual hyper/hyposensitivity, poor facial recognition, lack of eye contact, and visual-motor integration impairments. Case Summary: A 10-year-old autistic male was referred for diagnosis of convergence insufficiency. There were notable developmental delays and concerns primarily regarding reading comprehension, attention deficits, and spatial organization. He previously received speech and language therapies in conjunction with occupational therapy. Diagnostic testing of the patient’s ocular motility yielded tracking inefficiencies and poor accuracy. The Wachs Analysis of Cognitive Structures (WACS evaluation was performed and revealed weaknesses in a number of visualization tasks as well as in gross and fine motor coordination. An individualized program of vision therapy was recommended to improve his visualization, tracking, and visual motor integration abilities. Conclusion: This case report illustrates how the distinctive challenges of structuring a successful vision therapy program for the varying presentations of ASD can be met by adapting techniques to the appropriate developmental stage of the child. Vision therapy provides the framework to build skills that are transferrable and valuable in the classroom.

  15. Facial emotion recognition system for autistic children: a feasible study based on FPGA implementation.

    2015-11-01

    Children with autism spectrum disorder have difficulty in understanding the emotional and mental states from the facial expressions of the people they interact. The inability to understand other people's emotions will hinder their interpersonal communication. Though many facial emotion recognition algorithms have been proposed in the literature, they are mainly intended for processing by a personal computer, which limits their usability in on-the-move applications where portability is desired. The portability of the system will ensure ease of use and real-time emotion recognition and that will aid for immediate feedback while communicating with caretakers. Principal component analysis (PCA) has been identified as the least complex feature extraction algorithm to be implemented in hardware. In this paper, we present a detailed study of the implementation of serial and parallel implementation of PCA in order to identify the most feasible method for realization of a portable emotion detector for autistic children. The proposed emotion recognizer architectures are implemented on Virtex 7 XC7VX330T FFG1761-3 FPGA. We achieved 82.3% detection accuracy for a word length of 8 bits. PMID:26239162

  16. On the application of Quantitative EEG for characterizing autistic brain: a systematic review

    Directory of Open Access Journals (Sweden)

    Lucia Billeci

    2013-08-01

    Full Text Available Autism Spectrum Disorders (ASD are thought to be associated with abnormalities in neural connectivity at both the global and local levels. Quantitative electroencephalography (QEEG is a non-invasive technique that allows a highly precise measurement of brain function and connectivity. This review encompasses the key findings of QEEG application in subjects with ASD, in order to assess the relevance of this approach in characterizing brain function and clustering phenotypes. QEEG studies evaluating both the spontaneous brain activity and brain signals under controlled experimental stimuli were examined. Despite conflicting results, literature analysis suggests that QEEG features are sensitive to modification in neuronal regulation dysfunction which characterize autistic brain. QEEG may therefore help in detecting regions of altered brain function and connectivity abnormalities, in linking behavior with brain activity, and subgrouping affected individuals within the wide heterogeneity of ASD. The use of advanced techniques for the increase of the specificity and of spatial localization could allow finding distinctive patterns of QEEG abnormalities in ASD subjects, paving the way for the development of tailored intervention strategies.

  17. Autistic fluid intelligence: Increased reliance on visual functional connectivity with diminished modulation of coupling by task difficulty

    Directory of Open Access Journals (Sweden)

    Isabelle Simard

    2015-01-01

    Full Text Available Different test types lead to different intelligence estimates in autism, as illustrated by the fact that autistic individuals obtain higher scores on the Raven's Progressive Matrices (RSPM test than they do on the Wechsler IQ, in contrast to relatively similar performance on both tests in non-autistic individuals. However, the cerebral processes underlying these differences are not well understood. This study investigated whether activity in the fluid “reasoning” network, which includes frontal, parietal, temporal and occipital regions, is differently modulated by task complexity in autistic and non-autistic individuals during the RSPM. In this purpose, we used fMRI to study autistic and non-autistic participants solving the 60 RSPM problems focussing on regions and networks involved in reasoning complexity. As complexity increased, activity in the left superior occipital gyrus and the left middle occipital gyrus increased for autistic participants, whereas non-autistic participants showed increased activity in the left middle frontal gyrus and bilateral precuneus. Using psychophysiological interaction analyses (PPI, we then verified in which regions did functional connectivity increase as a function of reasoning complexity. PPI analyses revealed greater connectivity in autistic, compared to non-autistic participants, between the left inferior occipital gyrus and areas in the left superior frontal gyrus, right superior parietal lobe, right middle occipital gyrus and right inferior temporal gyrus. We also observed generally less modulation of the reasoning network as complexity increased in autistic participants. These results suggest that autistic individuals, when confronted with increasing task complexity, rely mainly on visuospatial processes when solving more complex matrices. In addition to the now well-established enhanced activity observed in visual areas in a range of tasks, these results suggest that the enhanced reliance on visual

    2005-07-01

    Full Text Available Abstract Background A wide range of abnormalities has been reported in autistic brains, but these abnormalities may be the result of an earlier underlying developmental alteration that may no longer be evident by the time autism is diagnosed. The most consistent biological finding in autistic individuals has been their statistically elevated levels of 5-hydroxytryptamine (5-HT, serotonin in blood platelets (platelet hyperserotonemia. The early developmental alteration of the autistic brain and the autistic platelet hyperserotonemia may be caused by the same biological factor expressed in the brain and outside the brain, respectively. Unlike the brain, blood platelets are short-lived and continue to be produced throughout the life span, suggesting that this factor may continue to operate outside the brain years after the brain is formed. The statistical distributions of the platelet 5-HT levels in normal and autistic groups have characteristic features and may contain information about the nature of this yet unidentified factor. Results The identity of this factor was studied by using a novel, quantitative approach that was applied to published distributions of the platelet 5-HT levels in normal and autistic groups. It was shown that the published data are consistent with the hypothesis that a factor that interferes with brain development in autism may also regulate the release of 5-HT from gut enterochromaffin cells. Numerical analysis revealed that this factor may be non-functional in autistic individuals. Conclusion At least some biological factors, the abnormal function of which leads to the development of the autistic brain, may regulate the release of 5-HT from the gut years after birth. If the present model is correct, it will allow future efforts to be focused on a limited number of gene candidates, some of which have not been suspected to be involved in autism (such as the 5-HT4 receptor gene based on currently available clinical and

    Individuals differ in their ability to feel their own and others’ internal states, with those that have more autistic and less empathic traits clustering at the clinical end of the spectrum. However, when we consider semantic competence, this group could compensate with a higher capacity to imagine the meaning of words referring to emotions. This is indeed what we found when we asked people with different levels of autistic and empathic traits to rate the degree of imageability of various kinds of words. But this was not the whole story. Individuals with marked autistic traits demonstrated outstanding ability to imagine theoretical concepts, i.e., concepts that are commonly grasped linguistically through their definitions. This distinctive characteristic was so pronounced that, using tree-based predictive models, it was possible to accurately predict participants’ inclination to manifest autistic traits, as well as their adherence to autistic profiles – including whether they fell above or below the diagnostic threshold – from their imageability ratings. We speculate that this quasi-perceptual ability to imagine theoretical concepts represents a specific cognitive pattern that, while hindering social interaction, may favor problem solving in abstract, non-socially related tasks. This would allow people with marked autistic traits to make use of perceptual, possibly visuo-spatial, information for “higher” cognitive processing. PMID:27303325

    Studies in child language have shown that contrastive stress appears to be an early developing device to mark the topic-comment distinction, and thus is important for the acquisition of pragmatic knowledge. This study examined the use of contrastive stress by autistic children with mean-length-of-utterance (MLU) scores between 1.9 and 4.1 morphemes. Normal and aphasic subjects at similar MLU levels served as contrast groups. The contrastive stress task required that the subjects verbally assess the counterfactual nature of a presupposition in a yes-no question. Toy manipulation was used to elicit the desired responses in a play situation. Listener judgment served as the basis for analyzing results. Although all subject groups were able to perform the task, differences were seen in the number of correct responses and the patterns of stress misassignment . PMID:6201678

    We acquired large data sets of calendar performance from two autistic calendar savants, DG and RN. An analysis of their errors and reaction times revealed that (1) both individuals had knowledge of calendar information from a limited range of years; (2) there was no evidence for the use of memorized anchor dates that could, by virtue of counting away from the anchors, allow correct responses to questions about other dates; and (3) the two individuals differed in their calendar knowledge, as well as in their ability to perform secondary tasks in which calendar knowledge was assessed indirectly. In view of the fact that there are only 14 possible annual calendars, we suggest that both savants worked by memorizing these 14 possible calendar arrangements. PMID:17686947

    2013-01-01

    Individuals with autism who show high abilities are called savants. Whereas in their brains a disconnection in and between neural networks has been identified, savantism is yet poorly understood. Focusing on astrocyte domain organization, it is hypothesized that local astrocyte mega-organizations may be responsible for exerting high capabilities in brains of autistic savants. Astrocytes, the dominant glial cell type, modulate synaptic information transmission. Each astrocyte is organized in non-overlapping domains. Formally, each astrocyte contacting n-neurons with m-synapses via its processes generates dynamic domains of synaptic interactions based on qualitative computation criteria, and hereby it structures neuronal information processing. If the number of processes is genetically significantly increased, these astrocytes operate in a mega-domain with a higher complexitiy of computation. From this model savant abilities are deduced.

  3. Discrepancy between WISC-III and WISC-IV Cognitive Profile in Autism Spectrum: What Does It Reveal about Autistic Cognition?

    Full Text Available The cognitive profile and measured intellectual level vary according to assessment tools in children on the autism spectrum, much more so than in typically developing children. The recent inclusion of intellectual functioning in the diagnostic process for autism spectrum disorders leads to the crucial question on how to assess intelligence in autism, especially as some tests and subtests seem more sensitive to certain neurodevelopmental conditions. Our first aim was to examine the cognitive profile on the current version of the most widely used test, the Wechsler Intelligence Scales for Children (WISC-IV, for a homogenous subgroup of children on the autism spectrum, i.e. corresponding to DSM-IV diagnosis of "autism". The second aim was to compare cognitive profiles obtained on the third edition versus 4th edition of WISC, in order to verify whether the WISC-IV yields a more distinctive cognitive profile in autistic children. The third aim was to examine the impact of the WISC-IV on the cognitive profile of another subgroup, children with Asperger's Syndrome. 51 autistic, 15 Asperger and 42 typically developing children completed the WISC-IV and were individually matched to children who completed the WISC-III. Divergent WISC-IV profiles were observed despite no significant intelligence quotient difference between groups. Autistic children scored significantly higher on the Perceptual Reasoning Index than on the Verbal Comprehension Index, a discrepancy that nearly tripled in comparison to WISC-III results. Asperger children scored higher on the VCI than on other indexes, with the lowest score found on the Processing Speed Index. WISC-IV cognitive profiles were consistent with, but more pronounced than WISC-III profiles. Cognitive profiles are a valuable diagnostic tool for differential diagnosis, keeping in mind that children on the autism spectrum might be more sensitive to the choice of subtests used to assess intelligence.

    This review focuses on identifying up-to-date number of publications that compared DSM-IV/ICD-10 Asperger's disorder (AspD) to Autistic Disorder/High-functioning Autism (AD/HFA). One hundred and twenty-eight publications were identified through an extensive search of major electronic databases and journals. Based on more than 90 clinical variables been investigated, 94 publications concluded that there were statistically significant or near significant level of quantitative and/or qualitative differences between AspD and AD/HFA groups; 4 publications found both similarities and differences between the two groups; 30 publications concluded with no differences between the two groups. Although DSM-5 ASD will eliminate Asperger's disorder. However, it is plausible to predict that the field of ASD would run full circle during the next decade or two and that AspD will be back in the next edition of DSM. PMID:23644916

    2016-01-01

    Full Text Available Multivariate pattern analysis (MVPA has been applied successfully to task-based and resting-based fMRI recordings to investigate which neural markers distinguish individuals with autistic spectrum disorders (ASD from controls. While most studies have focused on brain connectivity during resting state episodes and regions of interest approaches (ROI, a wealth of task-based fMRI datasets have been acquired in these populations in the last decade. This calls for techniques that can leverage information not only from a single dataset, but from several existing datasets that might share some common features and biomarkers. We propose a fully data-driven (voxel-based approach that we apply to two different fMRI experiments with social stimuli (faces and bodies. The method, based on Support Vector Machines (SVMs and Recursive Feature Elimination (RFE, is first trained for each experiment independently and each output is then combined to obtain a final classification output. Second, this RFE output is used to determine which voxels are most often selected for classification to generate maps of significant discriminative activity. Finally, to further explore the clinical validity of the approach, we correlate phenotypic information with obtained classifier scores. The results reveal good classification accuracy (range between 69% and 92.3%. Moreover, we were able to identify discriminative activity patterns pertaining to the social brain without relying on a priori ROI definitions. Finally, social motivation was the only dimension which correlated with classifier scores, suggesting that it is the main dimension captured by the classifiers. Altogether, we believe that the present RFE method proves to be efficient and may help identifying relevant biomarkers by taking advantage of acquired task-based fMRI datasets in psychiatric populations.

  9. Diminished medial prefrontal activity behind autistic social judgments of incongruent information.

    Takamitsu Watanabe

    Full Text Available Individuals with autism spectrum disorders (ASD tend to make inadequate social judgments, particularly when the nonverbal and verbal emotional expressions of other people are incongruent. Although previous behavioral studies have suggested that ASD individuals have difficulty in using nonverbal cues when presented with incongruent verbal-nonverbal information, the neural mechanisms underlying this symptom of ASD remain unclear. In the present functional magnetic resonance imaging study, we compared brain activity in 15 non-medicated adult males with high-functioning ASD to that of 17 age-, parental-background-, socioeconomic-, and intelligence-quotient-matched typically-developed (TD male participants. Brain activity was measured while each participant made friend or foe judgments of realistic movies in which professional actors spoke with conflicting nonverbal facial expressions and voice prosody. We found that the ASD group made significantly less judgments primarily based on the nonverbal information than the TD group, and they exhibited significantly less brain activity in the right inferior frontal gyrus, bilateral anterior insula, anterior cingulate cortex/ventral medial prefrontal cortex (ACC/vmPFC, and dorsal medial prefrontal cortex (dmPFC than the TD group. Among these five regions, the ACC/vmPFC and dmPFC were most involved in nonverbal-information-biased judgments in the TD group. Furthermore, the degree of decrease of the brain activity in these two brain regions predicted the severity of autistic communication deficits. The findings indicate that diminished activity in the ACC/vmPFC and dmPFC underlies the impaired abilities of individuals with ASD to use nonverbal content when making judgments regarding other people based on incongruent social information.

    [Purpose] One of the characteristics of autistic children is social interaction difficulties. Although therapeutic toys can promote social interaction, however its related research remains insufficient. The aim of the present study was to build a set of cooperative play toys that are suitable for autistic children. [Subjects and Methods] This study used an innovative product design and development approach as the basis for the creation of cooperative play toys. [Results] The present study has successfully developed cooperative play toys. Compared to the traditional game therapy for autism, cooperative play toy therapy can significantly improve the interactions between autistic children and their peers. [Conclusion] The most critical design theme of cooperative play toys focuses on captivating the interest of autistic children. Based on the needs of the individual cases, the design of the therapeutic toy set was specifically tailored, i.e., by reinforcing the sound and light effects to improve the attractiveness of the toys. In the future, different play modes can be combined with this toy set to further enhance the degree of interaction of autistic children and improve their quality of life and social skills.

    This study investigated hypothetical moral choices in adults with high-functioning autism and the role of empathy and alexithymia in such choices. We used a highly emotionally salient moral dilemma task to investigate autistics’ hypothetical moral evaluations about personally carrying out harmful utilitarian behaviours aimed at maximizing welfare. Results showed that they exhibited a normal pattern of moral judgments despite the deficits in social cognition and emotional processing. Further analyses revealed that this was due to mutually conflicting biases associated with autistic and alexithymic traits after accounting for shared variance: (a) autistic traits were associated with reduced utilitarian bias due to elevated personal distress of demanding social situations, while (b) alexithymic traits were associated with increased utilitarian bias on account of reduced empathic concern for the victim. Additionally, autistics relied on their non-verbal reasoning skills to rigidly abide by harm-norms. Thus, utilitarian moral judgments in autism were spared due to opposite influences of autistic and alexithymic traits and compensatory intellectual strategies. These findings demonstrate the importance of empathy and alexithymia in autistic moral cognition and have methodological implications for studying moral judgments in several other clinical populations.

    Although the importance of biological and genetic aspects of the etiology is well recognized, the pathological process of autism still remains to be elucidated. In contrast to a qualitative dichotomy concept, a dimensional perspective that places the autistic traits as quantitative extremes can easily explain the diversity and subtlety of the clinical features. In a dimensional (quantitative continuum) condition, no single qualitative process can distinguish the extremes from normal variations. In addition, the traditional view, which regards autism as a hypo-reproductive disease with a strong genetic contribution, cannot interpret the recent worldwide prevalence of autism. From a novel viewpoint, we have proposed 'the prenatal autistic imprinting hypothesis' in which autism is regarded as an inevitable consequence of human social evolution in both past and future. Postulated primary phenotypes are closely associated with the autistic savant skills and the autistic adherent temperament, and might increase the chance of specific prenatal experiences, named 'autistic imprinting'. An earlier prenatal brain growth and an earlier establishment of a type of consciousness may be critical for the imprinting process. A postnatal autistic social maladaptation may be a mere outcome of the putative intrauterine behavioral adaptation in individuals with the primary phenotypes. Both an autistic manner of thinking, which is referred to as 'visual thinking', and the prenatal early development of visual cortical architectures may play a key role in the autistic imprinting process.

    Full Text Available Background and Aims. The etiological factors involved in the etiology of autism remain elusive and controversial, but both genetic and environmental factors have been implicated. The aim of this study was to assess the levels and possible environmental risk factors and sources of exposure to mercury, lead, and aluminum in children with autism spectrum disorder (ASD as compared to their matched controls. Methods. One hundred ASD children were studied in comparison to 100 controls. All participants were subjected to clinical evaluation and measurement of mercury, lead, and aluminum through hair analysis which reflects past exposure. Results. The mean Levels of mercury, lead, and aluminum in hair of the autistic patients were significantly higher than controls. Mercury, lead, and aluminum levels were positively correlated with maternal fish consumptions, living nearby gasoline stations, and the usage of aluminum pans, respectively. Conclusion. Levels of mercury, lead, and aluminum in the hair of autistic children are higher than controls. Environmental exposure to these toxic heavy metals, at key times in development, may play a causal role in autism.

Since then there has been investigating the genesis of the autoimmunity caused by this microorganism and its clinical implications, since it has been associated with the obsessive-compulsive disorder, Tourette’s disorder and Sydenham’s chorea and with minor evidence it has been related to of hyperactivity disorder with lack of attention, autistic disorder and anorexia nervosa. The present article is a review on the most important aspects that have been defined up to now in regards to the physiopatlogy, clinical presentation and management of the patients with PANDAS spectrum, since they are a group of diseases in which it will be possible to change the paradigm of treatment in Psychiatry, from being a symptomatic disease to an etiological one.

  1. Numbers and letters: exploring an autistic savant's unpracticed ability.

    Pring, Linda; Hermelin, Beate

    2002-01-01

    This paper describes an individual with autism and high-level calendar calculation ability who could perform a set of unpracticed letter/number association tasks. The savant's performance was compared with that of two control participants, one a departmental secretary and the other a professor of mathematics. The facility with which the savant could master the rules governing the relationships between the series of items suggests that he possessed a flexibility of mental processing transcending his ability of calendar calculation. Furthermore, he could recalibrate previous knowledge to solve new hitherto unpracticed tasks. When presented with novel problems, the savant, unlike the mathematician, made no initial errors at all on any of the presented tasks, thereby indicating his fast and spontaneous recognition of new rules and of new relationships between items. It is concluded that a cognitive style of 'weak central coherence' as adopted by autistic savants may protect single representations from being retained in the form of stable enduring wholes, and that such a segmentation strategy may allow for the transformation, reorganization and reconstruction of the relationship between single items of information.

    Autism Spectrum Disorder (ASD) in DSM-5 comprises the former DSM-IV-TR diagnoses of Autistic Disorder, Asperger's Disorder and PDD-nos. The criteria for ASD in DSM-5 were considerably revised from those of ICD-10 and DSM-IV-TR. The present article compares the diagnostic criteria, presents studies on the validity and reliability of ASD, and discusses open questions. It ends with a clinical and research perspective.

    The purpose of this study was to understand the self-identity transformation in women with adolescent autistic children. In this study, in-depth interviews were used to collect data. Eight mothers were recruited who had autistic children aged 13-21 and who were those children's primary caregivers. Each mother was interviewed from one to four times. Four themes emerged through these mothers rethinking their connection with others during middle age. These included (1) relationships revisited; (2) self-awareness inspiration; (3) reconnection constructed; and (4) new self-identity formed. Results are hoped to provide valuable information for health professionals to understand how mothers of autistic adolescents connect with others and with their self-identity during middle age.

    Full Text Available Background: In this study, we investigated the developmental functions and autistic profilesin children with Fragile X syndrome (FXS. In addition, we establishedthe relationships between developmental and autistic profiles in these children.Methods: The medical records of 12 children with FXS, aged 2 to 7 years, were collected.Fifteen children with autism, without FXS, who were age- and sexmatchedwere selected as the comparison group. All children underwentassessments of developmental functions according to the Chinese ChildDevelopment Inventory (CCDI, and autistic profiles according to theChildhood Autism Rating Scale (CARS. Differences in genders between thetwo groups were determined with the Fisher’s exact test. Differences indevelopmental functions (CCDI and autistic profiles (CARS between thetwo groups were compared using Mann-Whitney U test and Bonferroniadjustment. The Spearman’s rho correlation was used to determine the relationshipof developmental functions and autistic profiles.Results: All developmental functions in children with FXS were better than thosewith autism except for gross motor, fine motor and expressive languagefunctions. Children with FXS had the worst expressive language function(56% Development Quotient, DQ as compared with other developmentalfunctions (> 70% DQ. The major difference between the children with FXSand those with autism was personal social function with a difference of 33%DQ. The average total CARS score were lower in children with FXS (averagescore, 28 than children with autism (average score, 34. Spearman’s correlationdemonstrated the CARS total score were negatively correlated withall developmental functions, except for gross motor function.Conclusions: Our findings suggest that the FXS children had multifaceted and disproportionaldevelopment patterns in motor, speech and social domains when comparedwith the autism children without FXS.

    Within the new DSM-5, the currently differentiated subgroups of "Autistic Disorder" (299.0), "Asperger's Disorder" (299.80) and "Pervasive Developmental Disorder" (299.80) are replaced by the more general "Autism Spectrum Disorder". With regard to a patient-oriented and expedient advising therapy planning, however, the issue of an empirically reproducible and clinically feasible differentiation into subgroups must still be raised. Based on two Autism-rating-scales (ASDS and FSK), an exploratory two-step cluster analysis was conducted with N=103 children (age: 5-18) seen in our social-pediatric health care centre to examine potentially autistic symptoms. In the two-cluster solution of both rating scales, mainly the problems in social communication grouped the children into a cluster "with communication problems" (51 % and 41 %), and a cluster "without communication problems". Within the three-cluster solution of the ASDS, sensory hypersensitivity, cleaving to routines and social-communicative problems generated an "autistic" subgroup (22%). The children of the second cluster ("communication problems", 35%) were only described by social-communicative problems, and the third group did not show any problems (38%). In the three-cluster solution of the FSK, the "autistic cluster" of the two-cluster solution differentiated in a subgroup with mainly social-communicative problems (cluster 1) and a second subgroup described by restrictive, repetitive behavior. The different cluster solutions will be discussed with a view to the new DSM-5 diagnostic criteria, for following studies a further specification of some of the ASDS and FSK items could be helpful.

    Bilingualism is common worldwide and increasingly prevalent, but there is little information about bilingual children with autism spectrum disorder. The goal of the study was to compare expressive and receptive language skills in monolingual English and bilingual English-Spanish children with autism spectrum disorder. A review of the multidisciplinary evaluations done in toddlers who were diagnosed with autism spectrum disorder at a university-affiliated center between 2003 and 2010 was performed. Data included demographics, developmental testing, autistic characteristics, and expressive and receptive language skills, obtained from formal speech and language evaluation. A total of 80 toddlers were identified, 40 classified as bilingual English-Spanish. Compared with monolinguals, bilingual children were more likely to vocalize and utilize gestures, with no other differences in language skills. There were no differences in cognitive functioning and autistic features between the groups. In this study, bilingualism did not negatively affect language development in young children with autism spectrum disorder. PMID:22859698

    Full Text Available The purpose of this study is to provide some background information on autism and how physical activity may be helping individuals with autism. Increasing rates of autism have been noted: Many researchers are involved in finding treatment methods that can help autistic children. Some studies have provided evidence that physical exercise and playing organized sport has been shown to be a beneficial intervention for the treatment of autistic individuals. The development of both motor and social skills has been seen to improve from physical exercise, which presents a challenge to individuals with autism.

    Full Text Available Adults show remarkable individual variation in the ability to detect felt enjoyment in smiles based on the Duchenne marker (AU6. It has been hypothesized that perceptual and attentional factors (possibly correlated to autistic-like personality traits in the normative range play a major role in determining individual differences in recognition performance. Here, this hypothesis was tested in a sample of 100 young adults. Eye-tracking methodology was employed to assess patterns of visual attention during a smile recognition task. Results indicate that neither perceptual-attentional factors nor autistic-like personality traits contribute significantly to individual differences in smile recognition.

    Many children with autism spectrum disorders (ASD) acquire a sizeable lexicon. However, these children also seem to understand and/or store the meanings of words differently from typically developing children. One of the mechanisms that helps typically developing children learn novel words is the shape bias, in which the referent of a noun is mapped onto the shape of an object, rather than onto its color, texture, or size. We hypothesized that children with Autistic Disorder would show reduce...

    Neuroimaging findings of autism has been the subjects of continuing investigation. Because previous study had not demonstrated consistent and specific neuroimaging findings of autism and most studies comprised adults and school-aged children, we performed a retrospective review in search of common functional and structural abnormalities in pre-school aged autistic children using Tc-99m ECD brain SPECT and MRI and compared them with age-matched children with nonautistic pervasive developmental disorders (PDD). 58 children between 3 and 8 years of age infantile autism (n=37) and non-autistic PDD (n=21) were performed Tc-99m ECD brain SPECT and MRI. Diagnosis of autism and non-autistic PDD was based on the criteria of DSM-IV and Childhood Autism Rating Scale (CARS). Of the 37 autistic patients, 32 revealed decreased perfusion of cerebellar hemisphere, followed by hypoperfusion of thalami (n=30), parietal cortex (n=16), temporal cortex (n=12). Of those 21 PDD patients, 14 patients showed hypoperfusion of the thalami and 10 patients showed temporal hypoperfusion. However, cerebellar hemispheric (n=8) and parietal (n=1) hypoperfusion was infrequently seen. All autistic and nonautistic PDD patients had normal MRI scan. Cerebellar hemispheric and parietal hypoperfusion on brain SPECT showed statistically significant correlation with CARS. Cerebellar hemispheric and parietal hypoperfusion is significantly frequently noted in autistic patients although they had normal MRI and SPECT may be useful and more sensitive modality in reflecting pathophysiology of autism as evidenced by previous MRI and postmortem studies. Thalamic and temporal hypoperfusion can be seen in both autistic and nonautistic patients and further studies are necessary to determine the significance of the thalamic hypoperfusion.

    2013-02-01

    Full Text Available Background: Explicit and implicit memories have different cerebral origins and learning approaches. Defective emotional words processing in children with autism may affect the memory allocated to such words. The aim of this study was comparing two types of (explicit and implicit memories during processing the two types of (emotional and non-emotional words in autistic children and their healthy counterparts. Materials and Methods: The present cross sectional study was conducted on 14 autistic children, who had referred to Autism Medical Treatment Center on Tehran, and 14 healthy children in kindergartens and schools across Tehran. For the explicit memory, a list of words was presented to the subjects of our study and they were asked to repeat the words they heard one time immediately and one time with delay. For implicit memory, the subjects were asked to identify the heard words among the presented words. Statistical analysis was performed using two-way analysis of variance. Results: The results showed that the normal children have higher efficiency in explicit and implicit memory than the children with autism (p<0.01. The two-way analysis of memory type and word type showed that the former affects memory significantly (p<0.05 while word type had no significant effect. Conclusion: Autistic children suffer from impaired memory. This defect is higher in implicit memory than in the explicit memory. It is recommended to apply rehabilitation, training, learning approaches and also explicit memory for interventions of autistic children.

  13. Attention and Word Learning in Autistic, Language Delayed and Typically Developing Children

    Directory of Open Access Journals (Sweden)

    ElenaTenenbaum

    2014-05-01

    Full Text Available Previous work has demonstrated that patterns of social attention hold predictive value for language development in typically developing infants. The goal of this research was to explore how patterns of attention in autistic, language delayed, and typically developing children relate to early word learning and language abilities. We tracked patterns of eye movements to faces and objects while children watched videos of a woman teaching them a series of new words. Subsequent test trials measured participants’ recognition of these novel word-object pairings. Results indicated that greater attention to the speaker’s mouth was related to higher scores on standardized measures of language development for autistic and typically developing children (but not for language delayed children. This effect was mediated by age for typically developing, but not autistic children. When effects of age were controlled for, attention to the mouth among language delayed participants was negatively correlated with standardized measures of language learning. Attention to the speaker’s mouth and eyes while she was teaching the new words was also predictive of faster recognition of the newly learned words among autistic children. These results suggest that language delays among children with autism may be driven in part by aberrant social attention, and that the mechanisms underlying these delays may differ from those in language delayed participants without autism.

  17. The evolution of autistic-like and schizotypal traits: A sexual selection hypothesis

    Directory of Open Access Journals (Sweden)

    Marco Del Giudice

    2010-08-01

    Full Text Available In this paper we present a new hypothesis on the evolution of autistic-like and schizotypal personality traits. We argue that autistic-like and schizotypal traits contribute in opposite ways to individual differences in reproductive and mating strategies, and have been maintained – at least in part – by sexual selection through mate choice. Whereas positive schizotypy can be seen as a psychological phenotype oriented to high mating effort and good genes displays in both sexes, autistic-like traits in their non-pathological form contribute to a male-typical strategy geared toward high parental investment, low mating effort, and long-term resource allocation. At the evolutionary-genetic level, this sexual selection hypothesis is consistent with Crespi and Badcock’s “imprinted brain” theory of autism and psychosis; the effect of offspring mating behavior on resource flow within the family connects sexual selection with genomic imprinting in the context of human biparental care. We conclude by presenting the results of an empirical study testing one of the predictions derived from our hypothesis. In a sample of 200 college students, autistic-like traits predicted lower interest in short-term mating, higher partner-specific investment, and stronger commitment to long-term romantic relations, whereas positive schizotypy showed the opposite pattern of effects.
