I noticed a few recent threads where people selfmedicated with alcohol. While those people are urged to stop (common sense and empirical evidence of what happens to chronic alcoholics), little explanations were provided for mechanisms.
Up to recently I only knew about etoh effects on dopamine and GABA signaling. I though D receptor downregulation and GABA receptor upregulation account for the depression that follows repeated etoh consumption (that made me almost stop using etoh at all).
Now, there is evedence that etoh has a rapid and profound anti-NMDA effects (dissociation, memory lapses, impairment, etc), followed by chronic NMDA receptor upregulation that can lead to depression and anxiety when a person stays sober. Even worse, combined with low magnesium, low zinc, and low thiamine (all natural NMDA modulators), common in alcoholics, that can produce brain damage via excitotoxicity.
There are many papers on this topic including this: http://journal.front...2013.00014/full
This shows how it's dangerous to chronically use any psychoactive substances, and etoh is amoung the worst, IMHO.
There is more. There is some evidence that stress has similar effect on NMDA: http://journals.plos...al.pone.0037916
Combine stress with alcohol (that is commonly used by countless as anti stress remedy), add genetic predisposition and you get the perfect storm. I believe that's exactly the source of my problems that started in University.
Unfortunately, countless young people (including members of my own family) go through the same path and damage brains in the process.
