“For centuries, doctors have recognized women’s vulnerability to depression and proposed a variety of explanations. The female of the species, with her ‘excitable nervous system,’ was thought to wilt under the strain of menstruation and childbirth, or later, the pressures of work and family.
But researchers are now constructing more scientific theories to explain why women are nearly twice as likely as men to become depressed. Social bias and women’s higher rates of physical and sexual abuse and poverty, experts say, clearly play a role. But scientists are also studying genes that may predispose girls and women to the disorder.” — New York Times
