Which State Has The Most (And Least) Mental Illness?

Nearly 20 percent of Americans -- 44.5 million adults -- experienced somesort of mental illnessover the last year, according to a new report from the U.S. Substance Abuse and Mental Health Agency (SAMHSA).

The report details state by state thepercent of the populationwho has suffered a mental illness.

“Mental illnesses are treatable and people can recover to live full, productive lives. Unfortunately in the past year only 37.9 percent of adults with mental health problems received any type of care,” SAMHSA Administrator Pamela S. Hyde said in a statement. “The chasm between need and care is costly both in terms of personal health because of missed opportunities to prevent disability and health care expenditures related to illness such as cardiovascular disease, diabetes, and obesity.”

The report counts "mental illness" as any sort of mental, behavioral or emotional disorder that is diagnosable from the DSM-IV. The disorder must cause "substantial functional impairment" or must be defined as a serious mental illness that requires treatment.
