Estrogen May Set the Stage
Ellen Leibenluft, M.D., Chief of the Unit on Rapid Cycling Bipolar Disorder at the National Institute of Mental Health, explained in a June 1998 Scientific American article that “[I]t now appears that estrogen might set the stage for depression indirectly by priming the body’s stress response. During stressful times, adrenal glandswhich set on top of the kidneys and are controlled by the pituitary gland in the brainsecrete levels of a hormone called cortisol. Cortisol increases the activity of the body’s metabolic and immune systems, among others. In the normal course of events, stress increases cortisol secretion, but these elevated levels have a negative feedback effect on the pituitary, so that cortisol levels gradually return to normal.”
“Evidence is emerging that estrogen might not only increase cortisol secretion, but also decrease cortisol’s ability to shut down its own secretion,” she added. “The result might be a stress response that is not only more pronounced but longer-lasting in women than in men.”
Such research is expected to provide partbut probably not allof the explanation for the gender gap in depressive conditions.
Small Pieces, Complex Puzzle
According to Leibenluft, figuring out why depression is more common among women than men is difficult work and progress is necessarily slow. But, she added, “What is coming into focus is that certain environmental factors including stress, seasonal changes and social rank may produce different physiological changes in females than they do in males. These findings are small pieces in what is proving to be an incredibly complex puzzle.”
