Autism is popularly viewed as a disorder of childhood, not old age, but that doesn’t mean senior citizens are unaffected.
Diagnosing autism is an evolving science but a crucial first step to understanding the disorder.
Children with autism understand fewer words than their verbal ability would suggest, according to a study published in December in the International Journal of Language and Communication Disorders.
Copy number variations, or CNVs — duplications or deletions of DNA segments — can influence the expression of unrelated genes on the same chromosome, according to a study published in November in PLOS Biology.
Scientists have created mice that carry mutations in SHANK3, one of the strongest candidate genes for autism. The animals have behavioral and neurobiological features reminiscent of autism, researchers reported 17 December in Molecular Autism.
Mice lacking one copy of a gene associated with Williams syndrome share the hyper-sociability of people with the disorder, according to a paper published online 3 December in Autism Research.
Teenagers with autism are less efficient at rapidly shifting their eye gaze — an indicator of motor ability — compared with either typically developing controls or adolescents with Asperger syndrome, according to a study published in November in Cerebellum.
