"In 1938, 5 percent of high school and college-age students were expressing symptoms of hypomania, a measure of anxiety and unrealistic optimism, and 1 percent suffered from serious depression. Now, more than 70 years after the Great Depression, more than 31 percent of high school and college students suffer from hypomania and 6 percent suffer from serious depression."   -  The Tech Talk (Jan 2010)

"[T]he tally of those who are so disabled by mental disorders that they qualify for Supplemental Security Income (SSI) or Social Security Disability Insurance (SSDI) increased nearly two and a half times between 1987 and 2007 - from one in 184 Americans to one in seventy-six. For children, the rise is even more startling - a thirty-five-fold increase in the same two decades. Mental illness is now the leading cause of disability in children."   -  The Raw Story (July 2011)
