Identify Personality Disorders


About 9 percent of the U.S. population is affected by 10 different and distinct personality disorders, according to the National Institute of Mental Health (NIMH).

If you know someone who you suspect has a personality disorder, it’s important to assist him or her in getting diagnosed and treated so that he or she can lead as normal of a life as possible.

What Is a Personality Disorder?

According to the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) of the American Psychiatric Association (APA), personality disorders are mental illnesses that are “associated with the ways of thinking and feeling about oneself and others that significantly and adversely affect how an individual functions in many aspects of life.”
