[Asperger's syndrome symptoms in children, adolescents and young adults].

Asperger's syndrome symptoms in children, adolescents and young adults. Asperger syndrome (AS) is a neurodevelopemental disorder which is classified into autism- spectrums disorders (ASDs). AS is characterized by significant difficulties in social interaction and nonverbal communication, stereotyped and restricted patterns of behaviour, activities and interests.

Tracking social motivation systems deficits: the affective neuroscience view of autism.

Abnormal functioning of primary brain systems that express and modulate basic emotional drives are increasingly considered to underlie mental disorders including autism spectrum disorders. We hypothesized that ASD are characterized by disruptions in the primary systems involved in the motivation for social bonding. Twenty adults with ASD were compared to 20 neurotypical participants on the basis of self-reports and clinical assessments, including the Social Anhedonia Scale (SAS) and the Affective Neuroscience Personality Scales (ANPS).

Levels of autistic traits in anorexia nervosa: a comparative psychometric study.

Background: A number of characteristics associated with Autism Spectrum Disorders (ASD) are over-represented among patients with Anorexia Nervosa (AN) as well as among relatives of these patients. Yet the co-occurrence of autistic traits in AN has not been fully explored and no previous study has directly compared self-reported evaluations of cognitive and socio-affective skills in AN and ASD.

Methods: We aimed to determine the degree of overlap between AN and ASD from scores on questionnaires classically used to measure ASD impairments.

Cortical folding in patients with bipolar disorder or unipolar depression.

Background: Analysis of cortical folding may provide insight into neurodevelopment deviations, which, in turn, can predispose to depression that responds particularly poorly to medications. We hypothesized that patients with treatment-resistant depression would exhibit measurable alterations in cortical folding.

Methods: We computed hemispheric global sulcal indices (g-SIs) in T(1)-weighted magnetic resonance images obtained from 76 patients and 70 healthy controls.
