Now, although that goal remains beyond the horizon, a growing number of reputable researchers at universities such as Stanford and Columbia say they can foresee a time when they'll be able to break the link between Down syndrome and retardation.
Armed with an array of new tools -- from genome mapping and stem cells to genetically engineered mice and a deepening understanding of Alzheimer's disease -- they are trying to pinpoint just how the extra chromosome of Down syndrome leads to retardation and a host of other problems.
