Exercise fights Alzheimer's brain damage

Regular exercise could help prevent brain damage associated with neurodegenerative diseases like Alzheimer's.

Regular exercise could help prevent brain damage associated with neurodegenerative diseases like Alzheimer's, according to research published in the journal Brain, Behavior, and Immunity.

The study used an experimental model of brain damage, in which mice are exposed to a chemical that destroys the hippocampus, an area of the brain which controls learning and memory. Mice that were exercised regularly prior to exposure produced an immune messenger called interleukin-6 in the brain, which dampens the harmful inflammatory response to this damage, and prevents the loss of function that is usually observed.
