Alcohol & the Brain

"Alcohol not broken down by the liver goes to the rest of the body, including the brain. 

Alcohol can affect parts of the brain that control movement, speech, judgment, and memory. 

These effects lead to the familiar signs of drunkenness: difficulty walking, slurred speech, memory lapses, and impulsive behavior. Long-term heavy drinking can shrink the frontal lobes of the brain, which impairs thinking skills."
