by  /  12 April 2011

There does not appear to be a single genetic or environmental cause of autism, and given the heterogeneity of symptoms, coming up with a clear yes or no test for autism is challenging. Timothy Roberts argues that imaging and electrophysiology are key in the search for autism biomarkers.

Regression, a sudden loss of language and social ability, does not lead to more severe autism, according to a study published in March in the Journal of Autism and Developmental Disorders. The study suggests that how autism develops does not influence the long-term outcome of children with the disorder.

Prenatal tests for autism mutations pose ethical dilemmas

by  /  31 March 2011

Genetic syndromes associated with autism are increasingly being diagnosed in utero because of techniques that can identify subtle mutations in the genome. But the technology is ahead of the ethical debate on whether and how to inform parents about mutations with unknown effects.
