The Selective Social Attention task in children with autism spectrum disorder: Results from the Autism Biomarkers Consortium for Clinical Trials (ABC-CT) feasibility study.

The Selective Social Attention (SSA) task is a brief eye-tracking task involving experimental conditions varying along socio-communicative axes. Traditionally the SSA has been used to probe socially-specific attentional patterns in infants and toddlers who develop autism spectrum disorder (ASD). This current work extends these findings to preschool and school-age children.

The autism biomarkers consortium for clinical trials: evaluation of a battery of candidate eye-tracking biomarkers for use in autism clinical trials.

Background: Eye tracking (ET) is a powerful methodology for studying attentional processes through quantification of eye movements. The precision, usability, and cost-effectiveness of ET render it a promising platform for developing biomarkers for use in clinical trials for autism spectrum disorder (ASD).

Methods: The autism biomarkers consortium for clinical trials conducted a multisite, observational study of 6-11-year-old children with ASD (n = 280) and typical development (TD, n = 119).

Reciprocal Copy Number Variations at 22q11.2 Produce Distinct and Convergent Neurobehavioral Impairments Relevant for Schizophrenia and Autism Spectrum Disorder.

Background: 22q11.2 deletions and duplications are copy number variations (CNVs) that predispose to developmental neuropsychiatric disorders. Both CNVs are associated with autism spectrum disorder (ASD), while the deletion confers disproportionate risk for schizophrenia.

Mapping 22q11.2 Gene Dosage Effects on Brain Morphometry.

Reciprocal chromosomal rearrangements at the 22q11.2 locus are associated with elevated risk of neurodevelopmental disorders. The 22q11.

Correlates of treatment-emergent mania associated with antidepressant treatment in bipolar depression.

Objective: Treatment-emergent mania can have substantial negative impact on overall mood and psychosocial stability in patients receiving treatment for bipolar depression. This study examined the correlates associated with treatment-emergent mania in patients receiving adjunctive antidepressant treatment for bipolar depression.

Method: A total of 176 adult outpatients with bipolar disorder in a 10-week trial of adjunctive antidepressant treatment for depression were categorized into three groups based on the Clinical Global Impression Scale for Bipolar Disorder: those who responded to antidepressant treatment (N=85), those who did not respond to antidepressant treatment (N=45), and those who had treatment-emergent mania or hypomania (N=46).
