A gene that plays a role in memory and learning also shapes the architecture of the aging brain in ways that may make people more vulnerable to Alzheimer’s disease, a team of Toronto researchers has discovered. Aristotle Voineskos of the Centre for Addiction and Mental Health said the gene causes subtle weaknesses in areas of the brain that are the first to be affected by Alzheimer’s. It is a common variant, carried by well over half the population, and is probably one of many risk factors related to the disease. The gene produces an essential protein that helps keep neurons alive and healthy, particularly in the memory centres of the brain. It also helps new brain cells to form.

Dr. Voineskos and his colleagues plan to investigate whether there are ways to boost its production and keep brain cells alive for longer. They hope to find a new way to identify people at risk for Alzheimer’s and ultimately a treatment for a disease that has proven stubbornly resistant to any of the drugs developed so far. “If we can manipulate it, we might be able to keep brain cells healthy for longer,” he said.  Read more: theglobeandmail.com
