Drinking and Memory
Moderate alcohol consumption can actually help memory in contrast with complete abstention. And no, binge-drinking does not help erase bad feelings. A new drunk rat study:
Among the normal rats, the animals that consumed moderate amounts of alcohol fared better on both tests compared with the teetotalers. Rats on a heavy alcohol diet did not do well on object recognition (and, in fact, showed signs of neurotoxicity), but they performed better than their normal brethren on the emotional memory task.
"People often drink to 'drown sorrows,'" Kalev says. "Our results suggest that this could actually paradoxically promote traumatic memories and lead to further drinking, contributing to the development of alcoholism."
