PERSONALITY DISORDERS

From the 7th Annual Psychiatry Review: The Impulsive-Compulsive Spectrum, presented by the University of Minnesota Medical School

ANTISOCIAL PERSONALITY DISORDER —Donald W. Black, MD, Professor of Psychiatry, Roy J. and Lucille A. Carver College of Medicine at the University of Iowa, Iowa City
Antisocial personality disorder: myths—“it doesn’t exist”; “it’s just bad behavior”; “improvement is impossible”; repercussions of myths—disorder largely ignored by mental health professionals and rarely diagnosed or studied (although in United States, only major depressive disorder more prevalent); patients rarely offered treatment; truths about antisocial personality disorder—culturally universal; high morbidity and mortality; enormous costs, especially in criminal justice system
Definitions: informal definition—disorder of lifelong, serial misbehavior; more formal definition—pattern of recurrent antisocial, delinquent, or criminal behavior that starts in childhood or early adolescence, and is manifested by disturbances in many areas of life, (eg, family relations, schooling, work, military service, and marriage); alternate terms—sociopathic personality; sociopathy; psychopathic personality; psychopathy; “antisocial does not mean being shy or inhibited [it] means that the person is antisociety and constantly violates societal norms”
Prevalence and risk factors: 2.5% to 3.5% of adult population in United States has antisocial personality disorder; disproportionate prevalence among prisoners (40% to 80%), homeless individuals (25%), and substance abusers (10% to 50%); second most common psychologic disorder in United States (not including substance abuse disorders);risk factors—male sex (2 to 7 times more common in men); low socioeconomic status; adoption (disproportionately high prevalence among adults adopted as children; relationship between adoption and development of antisocial personality disorder unknown)
Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria for antisocial personality disorder: A) pervasive pattern and disregard for rights of others since 15 yr of age; 3 of the following: 1) failure to conform, 2) deceitfulness, 3) impulsivity/failure to plan, 4) irritability/aggressiveness, 5) reckless disregard, 6) consistent irresponsibility, 7) lack of remorse; B) 18 yr of age; C) conduct disorder before 15 yr of age; D) schizophrenia/mania ruled out
Age-appropriate symptoms: children and adolescents—behaviors associated with conduct disorder (eg, getting into fights with other children, vandalism, lying to parents and teachers, teen delinquent behaviors); adults— criminality; domestic abuse; irresponsibility; work problems; substance abuse
Lack of conscience and/or remorse: individuals with antisocial personality disorder know about the concepts of conscience and remorse, but they do not experience them personally; in words of one author (Rule, 2000), “conscience is a factor that separates us from animals; it allows us to love, to feel another’s pain, and to grow; whatever the drawbacks, the rewards are essential to living in a world with other human beings ; the psychopath might as well be a visitor from another planet struggling to mimic the feelings of those he encounters”
Course and outcome: behaviors begin early (5 yr of age); chronic and lifelong disorder; 25% to 40% of children with conduct disorder develop antisocial personality disorder; some evidence of “burnout” (ie, attenuation) by late 30s to early 40s; prognostic factors (determined by 30-yr follow-up study)—severity of childhood symptoms; age at follow-up (disorder generally tends to improve with time); marriage (those who marry have better prognoses, but marriage may indicate less severe symptoms at outset); early incarceration (those incarcerated at earlier age have better prognoses; but therapeutic aspect of incarceration not identified); prognostic factors (from speaker’s study)—severity of adult syndrome at outset (directly correlated with severity at follow-up); age at follow-up (patients older at follow-up were doing better); abstinence from alcohol; time elapsed since hospitalization (symptoms improved as time increased) ; caveat—even when individual with antisocial personality disorder improves, he or she always remains behind peers in education, occupation, marriage, and family life; comorbidity—“is the rule”; common comorbidities include substance use disorders (alcohol abuse, 70%), mood disorders (lifetime depression, 25%), anxiety disorders, attention-deficit disorder, pathological gambling, and sexual deviancy
Theories of etiology: genetic theories—20% of first-degree relatives have disorder; high concordance in identical twins; adoption studies show biologic background likely indicator for development of antisocial personality disorder; biologic theories—brain injury; abnormal neurodevelopment; unresponsive nervous system; low serotonin; high testosterone; all biologic theories have some data to support them; damaged brain theory has most evidence (at least in subset of patients); history of head injury and abnormal findings on electroencephalogram common; imaging shows decreased prefrontal gray matter and changes in limbic system; social theories—poor parental bonding; poor parenting; abuse by parents; poor social environment; bad peers; media violence; bottom line—like other psychiatric disorders, antisocial personality disorder likely has multifactorial origin, and probably involves genetic vulnerability interacting with nongenetic factors
Treatment: no standard treatment or approved medication; no role for psychiatric hospitalization, unless patient suicidal or in need of substance abuse services; no randomized controlled trials published, so conclusions about treatment (or inability to treat) cannot be made
Management: managing psychiatric comorbidities (especially substance abuse) helps control antisocial behavior; no medication targets antisocial personality disorder; no particular medication routinely used; none approved by Food and Drug Administration (FDA); several drugs shown to reduce aggression
Medication in specialized populations: most medication advice based on highly specialized populations; some data from randomized controlled trials; prisoners—lithium and phenytoin associated with reduced aggression; children with conduct disorder—lithium, haloperidol, and divalproex; personality disorders—antipsychotics, mood stabilizers, antidepressants, and anxiolytics; brain injury—antidepressants
Psychotherapy: cognitive-behavioral treatment sometimes appropriate for mild cases; group therapy inappropriate; marriage and family therapy, support groups (eg, Alcoholics Anonymous [AA] or Gamblers Anonymous) and/or short-term community-based delinquency treatment programs may help
Problems in psychotherapy: patients—lack of motivation; lack of cooperation; poor follow-through; lack of insight; countertransference; therapists—“among therapists’ most common emotional reactions to antisocials is a feeling of fear”
Possible prevention strategies: targeting children with high-risk conduct disorder; early adjudication may help; parental-effectiveness training; social cognitive-skills training; note—children without conduct disorder do not develop antisocial personality disorder
IMPULSIVITY IN BORDERLINE PERSONALITY DISORDER (BPD)—S. Charles Schulz, MD, Professor and Head, Department of Psychiatry, University of Minnesota Medical School, Minneapolis
Introduction: impulsivity core symptom of BPD; manifestations include gambling, spending money irresponsibly, binge eating, substance abuse, engaging in unsafe sex, and driving recklessly; impulsivity may disrupt relationship between patient and therapist
Hypotheses to explain impulsivity in patients with BPD: low levels of serotonin; diminished effortful control (insufficient to prevent impulsive behaviors); behavioral addictions may appear as impulsivity, but might actually have different mechanism (eg, opioid pathways); comorbid disorders (eg, bipolar disorder) may lead to impulsive behavior
Approaches to psychobiology of personality disorders: study designed to explore normal attention and temperament used imaging to investigate metabolic activity in brains of patients with BPD; authors hypothesized that patients with BPD have high negative affect and low effortful control; findings indicated that deficit in executive attention could lead to core deficit of BPD in person with high negative affect; another study using positron emission tomography (PET) found significant inverse correlation between brain metabolic rates (in anterior-medial frontal cortex and right temporal lobe) and aggressive-impulsive tendencies in patients with personality disorder
Selective serotonin reuptake inhibitors (SSRIs): study looked at effects of fluoxetine in patients with BPD and schizotypal personality disorder; results suggested serotonergic dysregulation in both disorders, but must be viewed with caution because of open design; another study found fluoxetine (compared to placebo) associated with reduction in anger in patients with BPD (finding independent of drug’s effect on mood); third study found fluoxetine reduced irritability and aggression in patients with impulsive aggression; speaker concludes that when used in combination with psychotherapy, SSRIs may benefit patients with BPD; relatively high doses often required to achieve effect
Atypical antipsychotic medications: typical antipsychotic agents effective at controlling symptoms, but patients found adverse effects intolerable; data indicate that some atypical antipsychotics stimulate dopamine metabolism in frontal cortex, possibly increasing effortful control; olanzapine—study showed olanzapine reduced symptoms associated with BPD, helped with impulsivity, and was well tolerated by patients; follow-up study found olanzapine better than placebo for all symptoms (eg, anger, impulsivity, interpersonal difficulties) except depression; weight gain modest; authors concluded that olanzapine helpful for patients with BPD; at dose of 7 mg/day, no complaints of “feeling slow” or of being tremulous, but weight gain occurred; other studies confirm these findings; olanzapine-fluoxetine combination—as good as olanzapine alone and better than fluoxetine alone; other useful agents— risperidone, at doses about one half those used in schizophrenia, associated with decreased aggression; quetiapine (200 to 300 mg/day) associated with decreased depression, anxiety, and impulsivity; aripiprazole associated with reduced expression of anger
Anticonvulsant mood stabilizers: divalproex—most studied anticonvulsant; studies showed improved interpersonal sensitivity, anger, hostility, and overall aggression (independent of effect on mood); another study found it treated impulsivity and aggression only in patients with cluster B traits
Omega-3 fatty acids: preliminary reports showed benefit in patients with mood disorders; 2003 study showed safe and effective in women with BPD; patients expressed preference for omega-3 fatty acids over medication classes discussed above
Behavioral addiction: proposed theory suggests that individuals who cut themselves feel no pain; opiate antagonists may reduce self-injurious behavior if they cause patient to feel pain when cutting self; another hypothesis suggests addiction to self-injurious behavior, and opiate antagonists might help; one study found naltrexone helpful in reducing self-injurious behavior
Conclusions: impulsivity prominent in patients with BPD, but different pathophysiologic underpinnings of this behavior likely exist; multiple classes of medicine decrease impulsive symptoms and other symptoms in patients with BPD; combination with psychotherapy beneficial; reduction of impulsivity not correlated with changes in mood symptoms, so medication effect not likely secondary to treating comorbid mood disorders

Educational Objectives

The goal of this program is to educate the listener about the diagnosis and treatment of personality disorders. After hearing and assimilating this program, the clinician will be better able to:
1. Identify patients with antisocial personality disorder and differentiate it from shyness or being inhibited.
2. Discuss the course and outcome of antisocial personality disorder.
3. Describe the roles of psychopharmacology and psychotherapy in the treatment of antisocial personality disorder.
4. Assess the role of impulsivity in borderline personality disorder (BPD).
5. Select medications that might attenuate impulsivity in patients with BPD.
