Social interactions not rewarding for children with autism

by  /  23 July 2010

Children with autism have abnormally low brain activity in the ‘reward center’ of the brain when given money or shown a happy face, according to a study in Autism Research. These are the first imaging data to support the notion that children with autism derive less pleasure from social interactions compared with their healthy peers.

The biology of obsessive-compulsive disorder becomes even more baffling with the release of two new mouse models, each implicating a different type of brain cell.

Study finds weak genetic link between autism and intelligence

by  /  20 July 2010

Autism and intellectual disability often occur together, but in most cases that overlap is not genetic, according to a study of twin pairs published in the American Journal of Medical Genetics. Unraveling this link might help researchers pinpoint brain circuits involved in both conditions, and better understand the diversity of symptoms in the autism spectrum, experts say.

Chromosome 7 segment gives clues to complex social behavior

by  /  12 July 2010

Individuals carrying an extra copy of the genetic region that’s missing in Williams syndrome — which causes mental retardation and a hyper-friendly personality — have language impairments and other autism-like social difficulties, according to a wave of new research on this duplication syndrome.

Deep sequencing questions role of imprinted genes in autism

by  /  8 July 2010

The mouse brain has more than 1,300 regions for which the copy from one parent is expressed more often than the one from the other parent, according to two studies published today in Science. These so-called imprinted genes have been proposed to cause some cases of autism, but the researchers say their findings do not support that theory.

Abnormal brain growth seen in children with fragile X

by  /  7 July 2010

Children with fragile X syndrome show abnormal growth in several brain structures during the first few years of life, according to the first study to track how the disease unfolds in the brain during early development.

Synaptic defects link autism, schizophrenia

by  /  2 July 2010

Several independent groups have found previously unknown risk genes for autism, schizophrenia and mental retardation. The candidate genes have one thing in common: they encode proteins that are needed for the healthy function of synapses, the junctions between neurons.

Imaging interactions

by  /  1 July 2010

A clever new method records brain activity during live, back-and-forth social interactions and could help scientists study joint attention — the act of looking at an object the same time someone else does.

Simple pathway

by  /  24 June 2010

A study of a rare form of epilepsy found in Amish groups adds heft to the idea that mTOR — a much-studied hub in a massive network of brain cell proteins — is an important biochemical player in autism.
