Brief description Brain damage resulting from long-term alcohol abuse is localized to discrete regions of the brain and selectively impairs key neuropsychological functions. Alcohol misuse affects processes that control excitability in the brain, leading to the over-stimulation of brain cells. When this continues for long periods the cells are likely to die and most alcoholics misuse alcohol for most of their adult lives. We will study the human brain s capacity to use and respond to glutamate, its major natural excitant, in the regions that are selectively damaged by alcoholism. How these capacities are affected by heredity, and by diseases commonly associated with alcoholism such as cirrhosis of the liver, will also be explored. If we can understand how selective brain damage occurs in alcoholics we will be better able to devise new drug therapies to combat and prevent it. As well, localized brain damage is a feature of many neurological diseases, so the study will provide a general model of disease mechanisms.
