Molecular mechanisms: Autism linked to small hypothalamus

by  /  17 June 2011

Children with autism have less brain matter than normal in a region that synthesizes the social hormones oxytocin and vasopressin, according to a study published 29 April in Biological Psychiatry.

Brain overgrowth may drive early symptoms of autism

by  /  16 May 2011

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.

Diagnosing autism in children is difficult enough, but detecting the disorder in adults is even more complicated.

Molecular mechanisms: Men with fragile X have enlarged brains

by  /  9 February 2011

Men with fragile X syndrome have larger brains overall than controls do, but less matter in regions involved in language and social interaction.

Brain expands too fast, shrinks too soon in autism

by  /  7 February 2011

The brains of people with autism show three distinct periods of abnormal development — overgrowth in infancy, prematurely arrested growth in childhood, and shrinking between adolescence and middle age — according to a study in Brain Research.

Some siblings of children with autism only share traits

by  /  10 January 2011

The goal of studying siblings of children with autism is to identify an early diagnostic marker for the disorder. What researchers are finding instead are distinct traits shared by family members who remain healthy.

Scientists create mouse models of chromosome 16 defects

by  /  13 December 2010

Two independent groups have created mice that have deletions or duplications in a large section of chromosome 16. Each team has produced an animal with a different set of features, some of which — such as large head size and repetitive behaviors — are reminiscent of people with autism.

Large study pinpoints new genetic risk region for autism

by  /  19 November 2010

Deletion of the chromosomal region 17q12 dramatically increases the risk for autism and schizophrenia, according to a large study published last week in the American Journal of Human Genetics. Individuals missing this sizeable region are about 14 times more likely to develop one of those disorders, the study reports.

Brains of children with autism change as they grow up

by  /  17 November 2010

The brains of children with autism show differences in gene expression compared with those of healthy controls, especially in genes that control cell growth. Adults with autism also have aberrant gene expression, but in different pathways, researchers reported Sunday at the Society for Neuroscience annual meeting in San Diego.
