Drug May Counteract Down Syndrome

From http://www.sciam.com/



Researchers may have finally found a drug candidate for reducing the
mental retardation caused by Down syndrome, which afflicts more than
350,000 people in the U.S. Researchers gave low doses of a human drug
to mice bred to mimic the learning and memory problems in people with
Down syndrome. After as little as two weeks, the impaired mice
performed as well as normal ones in learning tests, and the improvement
lasted for up to two months after treatment ended.
