Summary: A new study by Northwestern University researchers details the biochemistry of how reduced blood flow to aging brains might contribute to Alzheimer’s. Regular exercise is the best way to improve that blood flow.
Have you made a New Year’s resolution to improve your diet and exercise? If so, it might reduce your risk of Alzheimer’s. A growing number of studies link lifestyle factors such as poor diet and lack of exercise to dementia, but it’s unclear exactly how these factors might contribute to the plaques and tangles some researchers think are responsible for the disease.

A new study by Dr. Robert Vassar and his colleagues at Northwestern University sheds light on one mechanism by which lifestyle might contribute to Alzheimer’s pathology. They conducted a complex series of experiments to show that reducing the amount of glucose available to brain cells sets off a chain reaction that increases beta amyloid, the protein involved in Alzheimer’s plaques.
