Alcohol-related brain damage is the damage that occurs to brain structures or function of the Central Nervous System as a result of the direct neurotoxic effects of alcohol intoxication or acute withdrawal. The frontal lobes are the most damaged region of the brains of alcohol abusers but other regions of the brain are also affected. The damage that occurs from heavy drinking/high blood alcohol levels causes impairments in judgement and decision making and social skills. These brain changes are linked to poor behavioural control and impulsivity, which tend to worsen the existing addiction problem.
