Alcohol and the Brain
Home / Alcohol's Effects on Health / Alcohol and the Brain
Alcohol interferes with the brain's communication pathways and can affect the way the brain looks and works.
Alcohol makes it harder for the brain areas controlling balance, memory, speech, and judgment to do their jobs,
resulting in a higher likelihood of injuries and other negative outcomes. Long-term, heavy drinking causes
alterations in the neurons, such as reductions in their size.
The developing brain is particularly vulnerable to effects of alcohol. Misuse of alcohol during adolescence and
early adulthood can alter the trajectory of brain development, resulting in long-lasting changes in brain structure
and function.
One significant consequence of alcohol misuse is alcohol-induced blackouts. Blackouts are gaps in a person's
memory for events that occurred while they were intoxicated. These gaps happen when a person drinks enough
alcohol to temporarily block the transfer of memories from short-term to long-term storage-known as memory
consolidation-in a brain area called the hippocampus.
Continuing to drink despite clear signs of significant impairments can result in an alcohol overdose. An alcohol
overdose occurs when there is so much alcohol in the bloodstream that areas of the brain controlling basic life-
support functions–such as breathing, heart rate, and temperature control-begin to shut down. Symptoms of
alcohol overdose include mental confusion, difficulty remaining conscious, vomiting, seizure, trouble breathing,
slow heart rate, clammy skin, dulled responses such as no gag reflex (which prevents choking), and extremely
low body temperature. Alcohol overdose can lead to permanent brain damage or death.
