by  /  1 December 2010

A variant of the autism risk gene CNTNAP2 may alter the brain to emphasize connections between nearby regions and diminish those between more distant ones, according to a study published 3 November in Science Translational Medicine.

‘Daydreaming’ circuit implicated in autism, attention deficit

by  /  24 November 2010

Areas of the brain that are active when people are daydreaming or sleeping, and quiet when they are engaged in a task, are imperfectly synchronized in people with autism and attention deficit hyperactivity disorder, researchers say.

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.

Variants in trust hormone receptor up the risk for autism

by  /  1 February 2010

Genetic variations that tweak the brain’s release of oxytocin — a hormone involved in social bonding and establishing trust — may increase the risk of developing autism or traits of the disorder, according to three new studies published in the past few months.

Schizophrenia risk genes tied to immunity, autism

by  /  24 July 2009

Several new genetic variants associated with schizophrenia lie in regions important for immune function and associated with autism. This suggests that both disorders stem partly from abnormal activation of the immune system, say some researchers.
