Alzheimers and HDL, the Good Cholesterol

December 18, 2010

The report, published in the Archives of Neurology, is not the first to find that what’s good for the body may also good for the brain. Numerous studies have found that older people who walked the most were at lowest risk of developing vascular dementia, possibly because the regular exercise improves cerebral blood flow and lowers the risk of vascular disease.

Regular physical activity, in general, is believed to improve brain function, both by increasing blood flow to the brain and by stimulating the production of hormones and nerve growth factors involved in new nerve cell growth. Exercise also raises levels of “good” HDL cholesterol. Studies have found that animals that are kept physically active have better memories and more cells in their hippocampus, a part of the brain critical for memory. And exercise can help stave off or keep in check diseases like Type 2 diabetes, which increase the risk of developing dementia.
