Alcohol-related dementia (ARD) refers to a form of dementia caused by long-term, excessive consumption of alcoholic beverages, resulting in neurological damage and impaired cognitive function.
Alcohol has a direct effect on brain cells, resulting in poor judgment, difficulty making decisions, and lack of insight. Nutrition problems which often accompany longtime alcohol abuse can be another contributing factor, since parts of the brain may be damaged by vitamin deficiencies.
