One-quarter of all Americans met the criteria for having a mental illness within the past year, and fully a quarter of those had a "serious" disorder that significantly disrupted their ability to function day to day, according to the largest and most detailed survey of the nation's mental health, published yesterday.
Then again, maybe the only real problem we have is one of defining mental illness if our current definitions encompass 1 out of every 4 people.
