Spotted around the web: Visual impairments; metabolomics; diagnosing girls

Abstract

Research roundupAutistic youth make up 11.5 percent of all the adolescents admitted to two psychiatric facilities in Canada, where 1.5 percent of the general population is autistic. Journal of Autism and Developmental Disorders Autistic and non-autistic children show similar visual-gaze responses to facial expressions of emotions when the emotion strength increases over time, but they respond differently when strong emotions are presented early in a sequence. Autism Research Rats prenatally exposed to valproic acid, a model of autism, have altered microbiota and lower levels of short-chain fatty acids in their gastrointestinal tract compared with control rats, and associated changes in brain neurotransmitters. Frontiers in Physiology Autistic people often have severe visual impairment for which early interventions can be helpful. Journal of Public Health Research The Depression Anxiety Stress Scales-21 outperforms the Center for Epidemiological Studies Depression Scale-Revised in assessing symptoms of mood disorders in autistic people. Journal of Autism and Developmental Disorders Early interventions in children with autism or at an elevated likelihood of the condition have limited impact on neurodevelopmental outcomes, according to a review of clinical studies. Autism ResearchA phospholipid imbalance during mid-pregnancy and dysregulation of many more metabolites at birth may serve as biomarkers for autism, according to a metabolomic analysis of blood. Molecular Psychiatry Mice missing the autism-linked gene CSMD3 display altered sociability, repetitive behaviors and motor problems, as well as changes in the form and function of cerebellar Purkinje cells. Journal of NeuroscienceAutistic girls, like non-autistic girls, use more words and speak more quickly than their male peers. Molecular Autism Autistic young people with genetic variants strongly linked to the condition tend to have
