To my understanding, one of alcohol's many effects is short-term interference with the brain's production of vasopressin, an anti-diuretic hormone which (strangely) also has some effect on memory formation.

I don't know about long-term effects on memory, but that's probably enough keywords for a medical journal search.

Heavy alcohol use among teens, even those who aren't dependent on it, has been shown to damage prospective memory well after the alcohol has cleared from their system. The damage lasts for months, at the very least.
