PERSONALITY DISORDERS Robert A. Bashford, M.D. Associate Professor Michael Hill, M.D. Associate Professor UNC Department of Psychiatry
What is a personality?? • A generally consistent (but personal) style of interacting with the world and other people • Our ‘character’ is reflected in how we think, what and who we like, and how we respond to life • It is generally stable over timeallows some predictability • Types of personality traits are limited and can be conceptualized as dimensional • No trait or style is automatically indicative of disorder or disease (don’t confuse eccentricity with disorder)
What is a disorder? • Implies functional impairment / failure to achieve what is expected and/or significant and persistent emotional distress • In the case of Personality Disorders this is by definition a result of a ‘maladaptive’ personality style
What are the most ‘basic’ expectations of our culture • Indepedence
What are the most ‘basic’ expectations of our culture • Indepedence • Follow the rules
What are the most ‘basic’ expectations of our culture • Indepedence • Follow the rules • Maintain long-term relationships
Personality Disorders An enduring pattern of inner experience and behavior that deviates markedly from the expectations of the individual’s culture. Manifested in two or more of the following: • (1) cognition • (2) affectivity • (3) interpersonal functioning • (4) impulse control
Personality Disorders • Pattern is enduring, inflexible, pervasive • Pattern is stable, of long duration • Not better accounted for by another mental disorder • Not due to substance or medical condition
Personality Disorders • Maladaptive behavior leads to poor life functioning • Ego syntonic (others are the root of all problems) • High incidence of co-morbidities (depression, anxiety, substance abuse) • Axis I disorders in PD patients are harder to treat • Difference between health and pathology one of degree (personality traits vs personality disorder)
How do personality disorders develop? • Genetic predispositions + environmental influences (including parenting, life experiences) + time = Personality formation • Obviously in a Personality disorder something in this complicated formula has gone wrong to lead to a maladaptive personality, but it is always very hard to pinpoint specific or simple causes.
What are the problems with Personality Disorders as a diagnostic category? • Labels are often pejorative • Diagnosis is contextual and thus somewhat arbitrary • Bad, obnoxious, hard-to-treat patients often get these labels whether justified or not • Treatment may be mis-directed
Personality Disorder Clusters • Cluster A - Odd, eccentric • Cluster B - Dramatic, emotional, erratic • Cluster C - Anxious, fearful
Cluster A Personality Disorders(‘odd & eccentric’) • Paranoid • Schizoid • Schizotypal • May be premorbid to schizophrenia in some cases
