Alcoholic Brain Damage
Chronic alcoholic brain damage is induced by excessive consumption of alcohol. Even moderate alcohol consumers, with no specific neurological or hepatic problems, may show some evidence of regional brain damage and cognitive dysfunction. Multiple epidemiological reports have demonstrated that there is a U‐shaped relationship between ethanol intake and general mortality, the lowest death rate correlating with low to moderate amounts of ethanol, 1–3 drinks per day (15–45 g), while abstaining from ethanol or excessive drinking was associated with higher mortality. Moderate ethanol consumption may be beneficial to health: lower cardiovascular diseases diminish the risk of dementia and Alzheimer’s disease in the elderly and may be protective against some forms of cancer.
