Treatment of age-associated memory impairment with guanfacine.

Alpha2 adrenergic agonists have been shown to improve memory test performance in amnesic humans and aged nonhuman primates. In a group of drugs in this class that were tested for their effects on age-related memory impairments in aged monkeys, guanfacine was the most effective for improving mnemonic function at doses that were without significant side effects. These data prompted studies of guanfacine for its effect on learning and memory in persons with age-associated memory impairment (AAMI), the results of which are now reported. The data suggest that guanfacine may have modest mood-improving effects but had no significant effects on learning and memory in the subjects tested.
