does dxm cause memory loss?

my friend & i were just talking & i told her last summer it seemed like everything changed, i can't pay attention in school (a lot less than i could before, i mean), I can't read books for more than 2 pages, i can't remember anything, it seems like, just doing all around worse at that kind of stuff.

We thought it might be the dxm, i've been taking it on average 1-2 times a week for a year, just 120-150 mg, but still she thinks it might be the dxm.
i looked on erowid, by the way, i go there all the time, doesn't say anything about low dose long term effects.
anyway thanks if you can help

Yes it could very well be the dxm thats responsible. 1 of the receptors it blocks normally receives glutamate; a amino acid that is believed to be one of the keys to learning and forming memories. So if you block that receptor with dxm, you're prolly gonna have a hard time learning and remembering things.

too bad :( is it permanent??

Probably not.

I had used dxm for a while and did experience some slight memory and learning problems, (Most only lasting for a few days.) but I think that those problems are now mostly if not completely gone and I've been off dxm for about 1.5-2 years.

I too used it on and off for about a year maybe a little longer, but I usually (not always) spaced my doses out to about twice a month, and they were always at least 300 mg, usually more.

I've done DXM like every 2 or 3 days for 3 months or so (a lot of you would say that's overboard but... I disagree. As long as you're responsible.) and I have suffered no ill effects from it. Other than weird hangovers.
