Missing Protein May Explain 'Rain Man'

Posted Feb 13, 08 4:27 PM CST in Science & Health 

(Newser) – The absence of a certain brain protein may play a role in the development of “autistic savants”—patients who exhibit the socio-cognitive impairments of autism but possess exceptional aptitude in highly specific areas, Live Science reports. Researchers found mice lacking the Shank1 protein, used for building synapses, learned one spatial memory task faster and better than normal mice despite having somewhat shriveled brains.

But weeks later, the altered mice couldn’t recall the superior skills they had learned and performed worse on the spatial task than the controls. "These opposite effects on different types of learning are reminiscent of the mixed features of autistic patients, who may be disabled in some cognitive areas but show enhanced abilities in others," said one of the researchers.

    Study Yields More Clues About Autism Scientists have found six new genes linked to autism, inching closer to a fuller understanding of the disorder and how to treat it, the AP reports. The genes in question are necessary for learning but are essentially stuck in the "off" position. The finding lends credence to the philosophy behind intensive education programs that seek to give the circuits an "extra push," said one expert.  More »
