Scientists finger neurexin 1 defects in autism

by  /  20 April 2010

Several studies in the past year in people, mice and honeybees have tied autism to a protein that helps neurons communicate. Problems with the protein, neurexin 1, are associated with a wide range of autistic behaviors, such as impaired social interactions, anxiety and problems with learning and memory.

Autism not a fundamental problem of attention, study says

by  /  16 April 2010

Toddlers with autism pay less attention to faces than do healthy controls, but both groups give equal attention to objects, according to a study published in the Archives of General Psychiatry. The findings challenge the idea that individuals with autism have a generalized problem with attention, suggesting instead that they struggle with attending specifically to social stimuli, researchers say.

Random genetic changes may explain variability in autism

by  /  13 April 2010

Random changes in gene expression can cause genetically identical embryos to develop different traits, according to a study of worms published in Nature. The findings suggest that haphazard movements of molecules could partly explain why autism-associated mutations don’t always cause the same symptoms.
