There's a common belief that every glass of alcohol you drink kills a certain number of brain cells. This is a myth I thought I'd clear up here, one that results from a severe condition sometimes seen in chronic alcoholics called Wernicke-Korsakov's Syndrome. http://www.ninds.nih.gov/disorders/wernicke_korsakoff/wernicke-korsakoff.htm The alcohol, itself, is not killing any neurons. The problem is that chronic drinking causes malabsorption of thiamine, coupled with the fact that many chronic alcoholics eat erratically and poorly. It is thiamine (vitamin B-1) deficiency that causes the neurological problems, not the consumption of alcohol itself. Alcohol doesn't kill brain cells.
