Understanding and treating the cognitive dysfunction of Down syndrome and Alzheimer's disease
Date:3/1/2012

ding AD hypothesis posits that it is caused by increasingly elevated levels of amyloid-related proteins, which are toxic to nerve cells in the brain. These same proteins also accumulate in the brains of people with DS because they are made by the APP gene, which is located on chromosome 21. Individuals with AD don't have the extra chromosome, of course; rather, it is mutations in APP that appear to cause the brain degeneration associated with AD.

Dr. John Krystal, editor of Biological Psychiatry, commented: "The convergence of research on Down syndrome and Alzheimer's disease highlights a central point that cannot be overstated. When we understand the fundamental biology of the brain, important new conceptual bridges emerge that guide new treatment approaches."

Salehi added, "In the near future, we may very likely look back with the perspective that Down syndrome represents an example of how families of affected individuals came together and by supporting basic research, changed the course of a disorder that was considered untreatable for more than a century."
