Many are closely related, so there are plenty that you can combine—like exercise and social activity—to get the benefits, says Dr. Kaiser. 8 Simple Ways To Improve Your Brain Health Long Term 1.
This may cause long-term changes in the structure and function of cerebral blood vessels.

This impairment results in periods of both reduced and excessive cerebral blood flow ...
