Saving Neurons and Memories

Physicians can treat the symptoms of Alzheimer’s disease and other neurodegenerative disorders, but there is no way to prevent or reverse the underlying degeneration and death of neurons that characterize these diseases. Now research by scientists at Harvard and MIT suggests a potential new therapeutic approach.

The scientists have shown that a gene called SIRT1 and a plant compound found in red wine called resveratrol can protect against neuron degeneration in a mouse model of Alzheimer’s disease and amyotrophic lateral sclerosis. The researchers demonstrated that activating SIRT1 and injecting resveratrol, which have both been previously associated with life-span extension in lower organisms, can also prevent cognitive problems in the mice.
