Alcohol can affect several parts of the brain, but, in general, contracts brain tissues, destroys brain cells, as well as depresses the central nervous system. Excessive drinking over a prolonged period of time can cause serious problems with cognition and memory.

What part of the central nervous system is affected by alcohol?

The brain, in particular, is significantly affected by alcohol causing issues with cognition and memory. Alcohol affects neurotransmitters in the brain, such as glutamate, which governs brain function. If you drink enough alcohol, its depressant effects can reduce your breathing and heart rate.

What system does drinking alcohol affect?

Organs known to be damaged by long-term alcohol misuse include the brain and nervous system, heart, liver and pancreas. Heavy drinking can also increase your blood pressure and blood cholesterol levels, both of which are major risk factors for heart attacks and strokes.
