46 percent are crazy at some time

Fox reports:

LOS ANGELES ? A new study by Harvard University and the National Institute of Mental Health claims that 46 percent of all Americans will, at some point in their lives, develop a mental disorder.

But this new statistic has experts arguing over exactly what constitutes a true mental illness.

According to experts, severe mental illnesses like schizophrenia, dementia and manic depression are relatively uncommon. But the updated Diagnostic and Statistical Manual of Mental Disorders, or DSM ? the standard survey for mental illness ? lists conditions like adjustment disorder, passive-aggressive disorder and female sexual arousal disorder as mental illness, reflecting what are claimed to be advances in the mental health profession.

Critics say that's crazy, and that it won't be long before all human quirks and flaws are classified as mental disorders.

Not all quirks. They refuse to classify certain deviant sexual practices as disorders.
