Alcohol-related brain damage[ 1][ 2] alters both the structure and function of the brain as a result of the direct neurotoxic effects of alcohol intoxication or acute alcohol withdrawal. Increased alcohol intake is associated with damage to brain regions including the frontal lobe, [ 3] limbic system, and cerebellum, [ 4] with widespread ...
Alcoholic polyneuropathy is a neurological disorder in which peripheral nerves throughout the body malfunction simultaneously. It is defined by axonal degeneration in neurons of both the sensory and motor systems and initially occurs at the distal ends of the longest axons in the body.

[ 2] On the other hand, research also shows that drinking moderate amounts of alcohol may protect healthy adults from ...
Alcoholic cardiomyopathy (ACM) is a disease in which the long-term consumption of alcohol leads to heart failure. [ 1] ACM is a type of dilated cardiomyopathy. The heart is unable to pump blood efficiently, leading to heart failure. It can affect other parts of the body if the heart failure is severe. It is most common in males between the ages ...
The long-term impact of alcohol on the brain has become a growing area of research focus. While researchers have found that moderate alcohol consumption in older adults is associated with better cognition and well-being than abstinence, [ 1] excessive alcohol consumption is associated with widespread and significant brain lesions.
Delirium tremens ( DTs; lit. 'mental disturbance with shaking') is a rapid onset of confusion usually caused by withdrawal from alcohol. [ 2] When it occurs, it is often three days into the withdrawal symptoms and lasts for two to three days. [ 2] Physical effects may include shaking, shivering, irregular heart rate, and sweating. [ 1]
