Alcohol-related brain damage 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,[1] limbic system, and cerebellum,[2] with widespread cerebral atrophy, or brain shrinkage caused by neuron degeneration.
Frontal lobe damage becomes the most prominent as alcoholics age and can lead to impaired neuropsychological performance in areas such as problem solving, good judgement, and goal-directed behaviors.[1] Impaired emotional processing results from damage to the limbic system. This may lead to troubles recognizing emotional facial expressions and “interpreting nonverbal emotional cues".[1]
Binge drinking, or heavy episodic drinking, can lead to damage in the limbic system that occurs after a relatively short period of time. This brain damage increases the risk of dementia and abnormalities in mood and cognitive abilities. Binge drinkers also have an increased risk of developing chronic alcoholism.
Alcoholism is also associated with many other health problems including memory disorders, high blood pressure, muscle weakness, heart problems, anaemia, low immune function, liver disease, disorders of the digestive system, and pancreatic problems. It has also been correlated with depression, unemployment and family problems with an increased risk of domestic abuse.
Parental history of alcoholism and/or binge drinking and gender has an influence on susceptibility to alcohol dependence as higher levels are typically seen in males and in those with a family history.[3]
