Does alcohol make you less intelligent?

Alcohol-use disorder is both preceded by and predictive of lower intelligence. Most studies of the relationship between alcohol use and intelligence scores are cross-sectional, leaving the question of cause and effect unresolved.

Does alcohol destroy brain cells?

Alcohol does kill brain cells. Some of those cells can be regenerated over time. In the meantime, the existing nerve cells branch out to compensate for the lost functions. This damage may be permanent.

Once brain cells die, the effect of the brain damage is permanent. Thankfully, some of the changes in the alcoholic brain are due to cells simply changing size in the brain. Once an alcoholic has stopped drinking, these cells return to their normal volume, showing that some alcohol-related brain damage is reversible.
