Can benzos protect from alcohol neurotoxicity?

Is it possible that low doses of benzodiazepines (Klonopin,Valium,Xanax) could protect from alcohol's neurotoxicity? Just a thought..
 
It does for amphetamines, But i don't see how one would think benzos could.

It could actually increace neurotoxity if anything, if somebody was passed out from alcohol poisoning.

Maybe in the non-chemical situation.

Where you normally drink a 5th of alcohol at a time.
But then find out, if you take xanax and drink 6 beers you get same effect.

You are then reducing neurotoxity. heh
 
i thought alchohol had a bit of nmda antagonism which would prevent damage from neurotoxicity
 
Yeah, there isn't a relation.
It reacts similar to alcohol, with the (GABA) and such

the drug is used for alcohol withdrawls, (hangover is considered part withdrawl).


and alcohol is very neurotoxic.

The majority (if not the entieity) of alcohol neurotoxicity is mediated by poor diet, not a direct effect of alcohol.
 
This is exactly why I posted this message. Whenever I go drinking, like for example right now I woke up from heavy drinking and 3 mg clonazepam and 20 mg diazepam yesterday before drinking - and have no hangover at all. Strange.. I tried digging Pubmed on this subject but cant find the connection. Oh and btw, I didnt eat at all during drinking and the amount of vodka was about 300-350ml.

What? I thought alcohol neurotoxicity was mediated throught its metabolite (I cant remember the name, something "formaldehyde" I think).
 
^isn't that the main chemical in embalming fluid?

bilzor do you mean to say that alcohol prevents certain nutrients from being absorbed or used?
 
I've read that arginine helps tremendously with hepatotoxicity/neurotoxicity (sorry I dont remember which one, I have a hangover but i definitely have read something about it) from alcohol. I'm too fatigued to open up Pubmed ;)
 
Alcohol is dehydrogenated by alcohol dehydrogenase, an enzyme in the liver. Alcohol - H --> Acetaldehyde + other stuff. It's acetaldehyde that you arre thinking of
 
I'm not sure what causes the thiamine deficiency which causes korsakov's syndrome. It's not the only form of alcohol-induced neurotoxicity, but it's one of the few that can be labeled.
 
I don't think benzos would have any positive effect on alcohol neurotoxicity, unless, as mentioned above, they induced you to drink less.

Olney's group has demonstrated that GABA(A) receptor potentiation mediates a component of alcohol-induced neurotoxicity in the fetal brain, and that benzos, which potentiate the receptor in a similar way, can have similar effects when given pre- or (I think) perinatally. However, this has only been shown to apply to the developing brain, and I think any such effect in the fully wired, adult brain, if it occurs at all, would be much less.
 
I think there is also form of excitotoxicity that can happen during withdrawal from serious alcoholism. Benzos might protect against that in part.
 
I read somewhere that alcohol blocks NMDA receptors (thats why you cannot remember much after a big night out), so those receptors up regulate themself over time on alcohol, and magnesium helps alot, because it is a natural NMDA receptor blocker, and it is the neuro excitoxity that can cause damage after you 'dry out'

I always take anti-oxidents after drinking alot, like grape-seed extract, milk thistle, ect.
