Why do people with fragile X syndrome, a genetic defect that is the best-known cause of autism and inherited mental retardation, recoil from hugs and physical touch - even from their parents? http://phys.org/news185114974.html Medicine & Health Thu, 11 Feb 2010 13:10:01 EST news185114974 New research provides insight into why fragile X syndrome, the most common known cause of autism and mental retardation, is associated with an extreme hypersensitivity to sounds, touch, smells, and visual stimuli that causes sensory overload and results in social withdrawal, hyperarousal, and anxiety. The study, published by Cell Press in the February 11 issue of the journal Neuron, uncovers a previously unknown developmental delay in a critical brain circuit that processes sensory information in a mouse model of fragile X syndrome. http://phys.org/news185027732.html Medicine & Health Wed, 10 Feb 2010 12:35:49 EST news185027732 (PhysOrg.com) -- Whether it’s the sound of a speeding car approaching from out of the blue, or the faint echo of footsteps following you along a dark street, such looming sounds not only make our ears prick up - but help us see better too. http://phys.org/news174917281.html Medicine & Health Fri, 16 Oct 2009 13:09:48 EST news174917281
