The document discusses personality disorders as defined by the DSM-IV. It describes the 10 specific personality disorders: paranoid, schizoid, schizotypal, antisocial, borderline, histrionic, narcissistic, avoidant, dependent, and obsessive-compulsive. These disorders are characterized by inflexible personality traits that impair functioning and cause distress. The disorders are grouped into clusters based on shared characteristics of odd/eccentric, dramatic/erratic, or anxious behavior patterns. Personality disorders typically emerge in teens and have enduring and consistent symptoms.
