Alcohol can kill brain cells, but from overactivity of withdrawals.
> Scientists postulate that this
syndrome [Alcohol Withdrawal] represents the hyperactivity
of neural adaptive mechanisms no
longer balanced by the inhibitory
effects of alcohol
> Increased NMDA receptor activity
significantly increases the amount
of calcium that enters nerve cells.
Although calcium is essential for
nerve cell function, an excess of this
substance within neurons has been
reported to produce cell toxicity or
death
