d-Amphetamine: effects on memory in a depressed population.
The effect of intravenous d-amphetamine on memory functions in a group of depressed patients was examined in a double-blind placebo-controlled study. Active drug administration resulted in an increase in verbal free recall but no change in cued recall, suggesting specific effects on memory processes. The level of psychological processing of the presented stimulus was shown to interact with drug-induced facilitation of recall. Improvement in memory of more shallowly processed material under amphetamine related significantly to subjects' base-line indices of noradrenergic function. Drug-induced changes in mood did not correlate with improvement in cognitive functioning. The interrelationships between biochemical determinants of mood and memory are discussed in light of these findings.
