Duplication of a region on the X chromosome leads to a genetic disorder characterized by severe autism, according to a study published 25 November in Annals of Neurology.
Autism and attention deficit hyperactivity disorder show genetic and neurobiological overlap, which may provide clues to the origin of both disorders, says Joel Nigg.
The results of two new studies support recommendations against the use of brain scans to diagnose autism.
The brains of mice that model Rett syndrome are smaller than normal overall and have differences in specific regions similar to those seen in people with the disorder, according to unpublished research presented Wednesday at the 2011 Society for Neuroscience annual meeting in Washington, D.C.
Individuals who carry an autism-linked common variant in the MET gene have abnormally low brain connectivity, according to unpublished research presented at the 2011 Society for Neuroscience annual meeting in Washington, D.C.
A well-studied mouse model of autism has a smaller-than-normal volume in several autism-associated brain regions.
Long bundles of neurons that connect key regions in the brain develop abnormally in the first year of life in children with autism, according to new findings presented Friday at the International Meeting for Autism Research in San Diego.
For nearly 20 years, Ralph Adolphs has been trying to figure out how the human amygdala works. An avid outdoorsman, Adolphs has run a dozen 50- and 100-mile races, and his colleagues say he approaches science with the same stamina and intensity. He has already published more than 100 scientific papers, several of them revealing intriguing ties between the amygdala and autism.
