Autism:A brain link to autism ♦ Brain differences in premature babies who later develop autism ♦ Scientists find new vessel for detecting autism

Taking antidepressants during pregnancy increases risk of autism by 87 percent Using antidepressants during pregnancy greatly increases the risk of autism, researchers have discovered. The findings are hugely important as six to ten percent of pregnant women are currently being treated for depression with antidepressants.
Scientists find new vessel for detecting autism Evidence of autism may be found in the composition and malfunction of the brain's blood vessels, a team of scientists has found. Their research sheds new light on the causes of autism, which previously had pointed to neurological make-up rather than to the vascular system, and identifies a new target for potential therapeutic intervention.
A brain link to autism Using a visual test that is known to prompt different reactions in autistic and normal brains, researchers have shown that those differences were associated with a breakdown in the signaling pathway used by GABA, one of the brain's chief inhibitory neurotransmitters.
Brain differences in premature babies who later develop autism Extremely premature babies run a much higher risk of developing autism in later childhood, and even during the neonatal period differences are seen in the brains of those who do, research concludes. The findings suggest that environmental factors can lead to autism.
