Infections during childhood increase the risk of mental disorders. A new study shows that the infections children contract during their childhood are linked to an increase in the risk of mental disorders during childhood and adolescence. This knowledge expands our understanding of the role of the immune system in the development of mental disorders. Source 2x.
Clues into early development of autism spectrum disorder. Researchers compared stem cells created from individuals with autism spectrum disorder (ASD) against stem cells created from those without ASD to uncover, for the first time, measurable differences in the patterns and speed of development in the ASD-derived cells.

Difference in brain connectivity may explain autism spectrum disorder. Researchers have identified a possible mechanism of human cognition that underlies autism spectrum disorders, or ASD. They found there was brain overconnectivity in the unimodal-subcortical connections and brain underconnectivity in the supramodal-subcortical connections for ASD individuals, as compared to the typically developing control group, suggesting a relationship between connectivity and the expression of ASD.

Viral infections during pregnancy linked to behavioral abnormalities in offspring. Male and female rats whose mother experienced a simulated viral infection during pregnancy behave abnormally, consistent with behavioral alterations in autism or schizophrenia. Source 6v.
Children of both young and old parents share risk for certain neurodevelopment disorders. Results of a new study reports that parental age is linked to the risk for the development of neuropsychiatric disorders in children, including autism spectrum disorder (ASD); attention-deficit/hyperactivity disorder (ADHD); obsessive-compulsive disorder (OCD); and Tourette's disorder/chronic tic disorder (TD/CT).

Single mutation leads to big effects in autism-related gene. A new study offers clues to why autism spectrum disorder (ASD) is more common in boys than in girls. National Institutes of Health scientists found that a single amino acid change in the NLGN4 gene, which has been linked to autism symptoms, may drive this difference in some cases. Source 9u.
Sensory neurons outside the brain drive autistic social behaviors, study suggests. A new study lends further evidence that the social behaviors tied to autism spectrum disorders (ASD) emerge from abnormal function of sensory neurons outside the brain. Source 4b.
Pregnant mother's immunity tied to behavioral, emotional challenges for kids with autism. Children with autism born to mothers who had immune conditions during their pregnancy are more likely to have behavioral and emotional problems, a new study has found. Offspring sex may also interact with maternal immune conditions to influence outcomes, particularly in terms of a child's cognition. Source 4o.
