This is not medical advice. Studies have shown that large doses of coenzyme Q10 have slowed the rate of brain cell death for those with Parkinson’s disease. Taken in combination with Vitamin C the studies have produced great results. Reducing stress and alcohol also slows brain cell death. A good multi-vitamin (antioxidant) and caloric restriction and simple lifestyle will reduce the rate of brain cell death. Foods to eat - Cranberries protect brain cells from the free-radical damage that normally occurs over time, thereby preserving cognitive and motor functions. Cranberries are so powerful in preserving brain function, researchers recently found, that by their antioxidant action they can reduce the severity of brain impairment following strokes. They protect against the brain cell damage that usually occurs in the early stages after a stroke. Exposure to a concentration of cranberry extract equivalent to about half a cup of whole cranberries resulted in a "50 percent reduction in brain cell death" http://www.psychologytoday.com/rss/pto-20031203-000001.html Side Note - Blackouts, or loss of memory for a period during drinking, are a physical effect of alcohol on the brain. They occur as alcohol cuts off the supply of oxygen to the brain. Lack of oxygen supply to the brain can kill tens of thousands of brain cells every time a person becomes intoxicated. http://www.oregoncounseling.org/ArticlesPapers/Documents/ETOHBIOFx.htm
