What happens to nerve cells in the brain destroyed by alcohol abuse?

Alcohol can affect the brain receptors and thus can interfere with the relay of communication between nerve cells. This suppresses the excitatory nerve pathway activity. Alcoholics usually develop neuro-cognitive deficits, neurodegeneration, and neuronal injury. Although the core mechanism remains elusive, the effects are said to include the clogging of capillaries and the delay of the blood transmission to the brain’s nerve cells.
