A father's search for a drug to treat Down syndrome

Dr. Alberto Costa is a physician and neuroscientist. His interest in discovering a cure for Down syndrome arose when his daughter Tyche was born with it. In 2007 he published a study that showed that giving mice with Down syndrome the Alzheimer’s drug memantine could improve their memory.

Now Costa has taken the next step: he is completing the first randomized clinical trial ever to take a drug that worked in mice with Down and apply it to humans with the disease, a milestone in the history of Down-syndrome research.

. . .But the effects of that revolution on Down research may yet be cut short. A competing set of scientists are on the cusp of achieving an entirely different kind of medical response to Down syndrome: rather than treat it, they promise to prevent it. They have developed noninvasive, prenatal blood tests which would allow for routine testing for Down syndrome in the first trimester of a pregnancy, raising the specter that many more parents would terminate an affected pregnancy. Some predict that one of the new tests could be available to the public within the year.

Costa, like others working on drug treatments, fears that the imminent approval of those tests might undercut support for treatment research, and even raises the possibility that children like Tyche will be among the last of a generation to be born with Down syndrome. NY Times
