Mother’s age is real factor in autism risk, study says

by  /  28 September 2009

Older women are much more likely to have a child with autism than are older men, according to a controversial report published in the September issue of the American Journal of Public Health.


New blood test measures levels of fragile X protein

by  /  22 September 2009

A new molecular screen allows researchers to determine for the first time the precise amounts of FMRP protein, whose absence in the brain causes fragile X syndrome.


Imaging study ties brain connection to sociability

by  /  15 September 2009

Scientists have linked a person’s social ability with the strength of a specific connection between two areas deep within the brain.


Family ties compel some scientists to tackle autism

by  /  9 September 2009

Many autism researchers began studying the disorder after a loved one’s diagnosis, but some struggle with the decision to enroll their children in studies.

New autism risk genes may bolster fetal testosterone theory

by  /  25 August 2009

A team of British researchers has garnered some of the first genetic evidence supporting their theory that sex hormones play a role in the development of autism.


Study raises questions about autism-gut connection

by  /  18 August 2009

Children with autism are no more likely than healthy children to have some of the gastrointestinal symptoms — such as diarrhea, acid reflux and abdominal discomfort — previously tied to the disorder, according to one of the first long-term investigations of the supposed link.


X chromosome helps unravel complex genetics of autism

by  /  11 August 2009

Genetic studies to date have identified variations linked to autism in 21 of the 23 human chromosomes. Now, using a variety of new, high-resolution techniques, scientists are mining one of these chromosomes — the X — for a more comprehensive set of genetic anomalies associated with the disorder.


Atomic close-up of brain proteins hints at diversity of autism

by  /  6 August 2009

Scientists have unveiled the complete structure of an interwoven complex of two types of brain proteins necessary for forming and maintaining connections between neurons.


Gene ties trust hormone to Williams syndrome and autism

by  /  3 August 2009

Studying the relatively well-defined genetics of Williams syndrome may help unravel the poorly understood genetic and neurobiological roots of autism, researchers say.
