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.

MeCP2 loss leads to smaller neurons in brain region

by  /  18 November 2009

Deleting MeCP2, the gene that’s mutated in Rett syndrome, alters both the size and function of neurons in the mouse brain — at least in one brain region, the locus ceruleus — according to a 30 September report in the Journal of Neuroscience.

Daniel Geschwind: After many detours, on the trail of autism’s genetics

by  /  17 February 2009

In the late 1990s, after Daniel Geschwind had established himself as an expert on the genetics of neurological diseases, a personal connection abruptly pulled him into autism research. Since then, he has participated in dozens of studies probing the genetic basis of autism and related neuro-developmental disorders.

Research clarifies serotonin’s link to autism

by  /  13 March 2008

Serotonin is most commonly talked about in association with depression and anxiety. But for nearly 50 years, hyperserotonemia ― an elevated level of blood serotonin ― has been noted in roughly a third of autism cases.
