title: Steroid hormones, memory and mood in a healthy elderly population.
abstract: Men (n = 31), women estrogen-users (n = 14), and women estrogen non-users (n = 41), whose average age was 72.1 +/- 5.6 years, were tested with a battery of psychological tests measuring verbal memory, visual memory, concentration and attention, language fluency and semantic memory, and mood. Plasma levels of testosterone (T), estradiol (E2), cortisol (CRT) and dehydroepiandrosterone-sulfate (DHEAS) were assessed by radioimmunoassay. The ratio of DHEAS to CRT was calculated to determine it's relationship to memory functioning. The men had higher T and DHEAS levels than both groups of women. Women estrogen-users had higher E2 levels than both men and estrogen non-users and the men had higher E2 levels and a higher DHEAS/CRT ratio than the estrogen non-users. There were no group differences in CRT levels. Men and estrogen-users had higher total (p < .01) and forward (p < .001) digit span scores compared with non-users. Women estrogen-users also had higher backward digit span scores than non-users (p < .05), while both groups of women performed better than men on category retrieval (p < .01). The implications of these findings with respect to hormonal influences on memory in elderly men and women are discussed.
