Everett Clinic neurologist Dr. Michael Chun talks about exercise and dementia on KOMO’s consumer spotlight with host Herb Weisbaum.
"People who exercise actually have less shrinkage in the area of the brain (hippocampus) that controls memory," said Dr. Chun. "We found that with all patients with Alzheimer's disease, this area of the brain shrinks. People who exercise regularly, they have less shrinkage, so this argues strongly that exercise reduces the chances of Alzheimer's disease."
"Something that is sustained, that is at least 15 minutes, better longer, like 20 minutes, and something that takes a little bit of effort," he said. "You should be a little winded, maybe you sweat a little under the collar. But it has to be sustained and it would be nice to get your heart rate up as well."
