Dehydroepiandrosterone (DHEA) is a hormone produced by the adrenal gland in concentrations that decrease with age. In humans low DHEA levels have been associated with a variety of adverse biological consequences, including increased cardiovascular disease, decreased immune function, decreased bone density, negative lipid profile and an increased fat to muscle ratio.~In this study, we investigate the effects on mood and behavior of DHEA in men and women with midlife-related mood disorders in a double-blind, placebo-controlled, crossover trial. We specifically ask whether increasing DHEA levels will mitigate any or all of the neurasthenia-like symptoms characteristic of these disorders.
Dehydroepiandrosterone (DHEA) is a hormone produced by the adrenal gland. As humans grow older the levels of DHEA naturally decrease. Low levels of DHEA have been associated with a variety of harmful effects, including increased heart disease, decreased immune system function, decreased bone density (osteoporosis), high cholesterol, and increased fat to muscle ratio.~Blood levels of DHEA and its sulfate form, DHEA-S, begin dropping when humans are in their 20's. By the time humans are in their 40's and 50's, levels of DHEA and DHEA-S levels are at 50% of their peak. Previous studies have shown that levels of these hormones are associated with feelings of well-being and enjoyment of leisure activities.~In this study researchers are interested in the effects on mood and behavior of DHEA in men and women with mid-life related mood disorders. Specifically, researchers would like to find out if increasing levels of DHEA will lessen the symptoms associated with these disorders.
