Has anyone heard of the research reported recently that pointed to a lack of Dopamine as one of the causes of alcoholism. If this research is true, it might be the reason why a number of people on this list who have reported having a history of drinking now have Parkinsons. It would seem to be the chicken and the egg argument all over again. Instead of drinking being the cause of Parkinsons, low Dopamine levels may be the cause of excessive drinking. ---- Mary Ann Ryan
