Sometimes I wonder if the number of people with Alzheimers has anything to do with the number of people that have started with Blood Pressure medications early. It seems to me that maybe the brain might profit by a little extra pressure to carry more oxygen to the brain cells. I know my aunt was much clearer headed when her blood pressure was up in the clouds somewhere. She had readings like 210/200. Was it an effort by her body to force blood flow around or through the Alzheimer plaques? I wish I knew.
