Personality Disorders in a Hospital Setting
Personality The totality of emotional and behavioral traits characterizing a person’s day-to- day living. Relatively stable and predictable under ordinary conditions
Personality Disorders Inflexible, maladaptive, exaggerated traits Pattern of behavior deeply ingrained and maladaptive in perceiving self, others, environment
DSM-IV-TR Axis I Major mental disorder Axis II Personality disorders Cluster A, B, C
Cluster A Paranoid Schizoid Schizotypal
Cluster B Antisocial Borderline Histrionic Narcissistic
Cluster C Avoidant Dependent Obsessive-compulsive Not Otherwise Specified (NOS)
Personality Disorder Classification Controversial, Problematic Diagnostic unreliability Preferential personality (co-existing conditions?) Shared characteristics (excessive number of PDs) Heterogeneity Inconsistent, unstable, arbitrary boundaries Inadequate literature coverage Too frequent use of NOS category
Proposal 1 Dimensional profile: narrative description of case, not only diagnostic classification, identifying fundamental maladaptive personality traits underlying its functioning
Proposal 2 Integrate the various personality disorders into Axis I diagnostic classification: e.g., depressive personality disorder will change to dysthymia, early onset.
Factors in behavior Genetic, temperamental, biological, psychological factors determine reaction of an individual towards others and environment throughout life and help form a pattern of behaviors typical for the individual.
Defense Mechanisms Unconscious mental processes that the ego (self) employs to free itself from conscious anxiety generated during interactions with others, its own instincts, reality, conscience Used to avoid an increase in conscious anxiety and/or depression
Defense Mechanism Types Fantasy Dissociation Denial Isolation Projection Splitting Passive-Aggressive Acting out Projective identification
Fantasy Fear of intimacy Schizoid behavior Aloofness Loneliness Creating imaginary life, companions Fears should be recognized in a reassuring, non-confrontational, not insistent manner.
Denial - Dissociation Unconscious covers-up for anxiety/other unpleasant emotions (e.g., fear) via exhibiting histrionic superficiality. Makes little of problems. May not remember important events of life and medical history. Caution to not make them more defensive Caution in not accepting histrionics at face value Allow to ventilate feelings and anxiety
Isolation Obsessive-compulsive Orderly Relates well Tells unnecessary details about self in cool collected manner Responds well to precise, systematic, rational information. Wants punctuality. Demands interest from physician, others. Often intelligent, able to control own care.
Projection Attribution of own feelings to others Fault-finding Prejudicial Hyper-vigilant Distrustful Avoid confrontation. Normal but concerned approach. May be useful to establish alliance and expose him/her to interpretations of other reasons for suspiciousness.
Splitting Divides people into good and bad Some staff members may be idealized Some staff members disparaged Disruptive behavior Gentle confrontation – no one is totally good or bad.
Passive-Aggression Anger turned against self (masochism) Shows as self-demeaning or self- destructive behavior (wrist-cutting) Hostility may be part of provocative behavior Often viewed as sadistic Allow ventilation of anger.
Acting Out (I) Tantrums Expression of ambivalent feelings conscious or unconscious Assaults without motivation, at times sudden Different types of abuse (physical, sexual, adults, children) At times no apparent guilt feelings Homicide may take place in uncontrolled aggression
Acting Out (II) Interviewer must be calm, good listener. Realize patient lost control and is agitated. How can I help if you keep screaming or being so upset?
Projective Identification Mainly present in Borderline Personality Disorder Aspect of self projected onto other. Coercion of the other to identify with the projected aspect. Projector and recipient feel some kind of union.
Paranoid Personality Disorder (I) Frequency – 0.5-2.5% Referrals from spouse, family, employer More frequent in men Higher in immigrants Higher in deaf Appears serious, humorless, suspicious Speech logical but with false premises Prejudice, projection, ideas of reference
Paranoid Personality Disorder (II) Fear of exploitation Jealous Disdains weak and impaired Businesslike, efficient Questions trustworthiness of friends A chronic condition that poses difficulty in living with spouse, friends, co-workers.
Schizoid Personality Disorder (I) About 7.5% of population Social withdrawal Discomfort in relating to people Introversion Constricted affect Isolated Lonely Prefers solitary job, also at night
Schizoid Personality Disorder (II) Avoids eye contact Fearful Short answers Minimal spontaneous speech Flattened affect Unable to relate Lives in fantasy world Repressed intimacy and sexuality
Schizoid Personality Disorder (III) Unable to express anger Pseudo-philosophizes Excessive day-dreaming Good patients in hospital who, absorbed in self, need protection from other patients (dyscontrolled or paranoid). If staff is able to establish rapport, they will uncover a plethora of day-dreaming.
Schizotypal Personality Disorder 3% of general population Odd, strange magical thinking Ideas of reference Illusions Peculiarity of thinking, behavior, appearance 10% commit suicide
Antisocial Personality Disorder (I) 3% male – 1 % female Nonconforming Antisocial Criminal behavior Callous Remorseless Prone to lying, irritability, rage Conduct disorder in childhood
Antisocial Personality Disorder (II) May have a veneer of normality, seductiveness Must be dealt with firmness and by establishing clear staff-patient rapport.

Borderline Personality Disorder (II) Proclivity to move into psychosis under intense stress Always in a state of crisis Argumentative, depressed No feelings Micropsychotic episodes Unpredictable Behavior
Borderline Personality Disorder (III) Repetitive self-destructive acts Self-mutilation- expresses anger Do well in hospital setting because of attention received, avoiding intrafamilial problems. Limits posed to behavior (self- destructive acts) in a supervised protected environment. Suicide attempts frequent.
Histrionic Personality Disorder (I) 2-3% of general population More frequent in women Found especially in mental institutional settings Colorful Extroverted Dramatic behavior Excitable Flamboyant
Histrionic Personality Disorder (II) Attention-seeking Frequently somatize Use drugs/alcohol Gesturing Eager to express and communicate in colorful way Some tangentiality and forgetfulness Magnify importance of events
Histrionic Personality Disorder (III) Mood swings and tears to make point Seductive, flirtatious, inconsistent Sensation seeking May get into trouble with law
Narcissistic Personality Disorder (I) 1% of general population Larger number in clinical setting Exaggerated sense of self-importance Enraged by criticism or completely ignores it Ambitious Continuous search for recognition Needs reassurance
Narcissistic Personality Disorder (II) Superficial relationships No empathy Cunning and exploitative Fragile self-esteem May become depressed Often rejected because of behavior Need structured firmness, clear understanding of procedures.

Avoidant Personality Disorder (II) Misperceives interviewing statements Needs and wants companionship May express fears of rejection Phobic avoidance Should be approached with friendly acceptance, made to feel wanted and appreciated.
Dependent Personality Disorder (I) Lack of self-confidence Relies on others Does not assume responsibility Passive, pessimistic, suggestible Lack emotional endurance Submissive Fear of expressing sexual/aggressive feelings
Dependent Personality Disorder (II) Unable to make decisions on their own Subject to abuse by others Patient should be told what has to be done. Should undergo behavior and assertiveness therapy/training.
Obsessive-Compulsive Personality Disorder (I) Perfectionist Obsessed with orderliness Obsessive thoughts Affect constricted Stiff, formal, rigid, stubborn Anal stage of development Want to be in control Detailed answers when interviewed
Obsessive-Compulsive Personality Disorder (II) Rationalization Intellectualizations Doing-undoing/ritualistic behavior Should be dealt with in matter-of-fact, rigid routine and a formal relationship.
Personality Disorder NOS Passive-aggressive Depressive Sado-masochistic Sadistic
Personality Changes due to a General Medical Condition Significant changes of habitual pattern of premorbid behavior ICD-10 Personality and Behavioral Disease due to: Brain disease Brain damage Brain dysfunction Post-encephalopathy Syndrome Post-concussion Syndrome
Personality Changes due to a Medical Condition ( I) Head trauma Cerebrovascular disease Cerebral tumor Epilepsy (partial complex epilepsy) Huntington’s Disease Multiple Sclerosis Endocrine disorders
Personality Changes due to a Medical Condition ( II) Heavy metal poisoning (manganese, mercury) Neurosyphillis Acquired Immune Deficiency Syndrome (AIDS)
Organic Personality Disorder Diagnostic Criteria (I) Alteration of habitual pattern of behavior Emotions, impulses and needs are affected Defective cognitive function consequences of actions/planning
Organic Personality Disorder Diagnostic Criteria (II) Perseverance in goal-directed activity reduced Unable to postpone gratification Emotional lability Euphoria, inappropriate jocularity Sudden shift from cheerfulness to irritability Outbursts of anger and aggression
Organic Personality Disorder Diagnostic Criteria (III) Apathy Impulsive actions w/ caring for consequences (stealing, sexual exposure/ advances, etc.) Suspiciousness Paranoid ideation, preoccupation (extreme) with religious or abstract themes Circumstantiality, viscosity
Organic Personality Disorder Diagnostic Criteria (IV) Alters sexual behavior Possibly violent behaviors, especially if intoxicated
Anabolic steroids (used to maximize muscle strength) may cause a persistent alteration of personality and behavior.
In dementia there is a global deterioration in intellectual and behavioral capacities. Personality changes in brain tumor, multiple sclerosis, Huntington’s Disease may evolve into dementia.
In general medical conditions personality changes show with: Cognitive disorder with significant memory loss, confusion, at times eventuating in dementia. Changes persist if cause persists. Trauma followed by coma. Delirium due to vascular accident
Personality changes in chronic intoxication, medical illness, drug therapy (levodopa for Parkinson’s Disease) may be reversed if cause is eliminated. Some patients need custodial care. Caution! Behavioral Dyscontrol
Neuroimaging Studies MRI CT scans PET-SPECT Minimal cortical atrophy, dilatation of lateral ventricles, hypermetabolism of basal ganglia
Schizotypal Personality Disorder Cluster A Larger ventricles (lateral) Smaller caudate and left hippocampus Larger hippocampus (R) Reduced prefrontal regions Decrease perfusion basal ganglia and thalamus
Borderline Personality Disorder (BPD) Cluster B Disinhibited aggression and affective instability associated with deficient top-down control of negative emotions
BPD: Impulsive aggression due to high level of anger ASPD: Aggressive behavior associated with less anger-stimulation and/or gain
Emotional Modulation Circuit (II) OFC (orbital frontal cortex) ACC ( anterior cingulate cortex) OFC and ACC interact to modulate response of amygdala
BPD Structural and Functional Studies Smaller total frontal lobe volumes Reduction in gray matter volume Reduction in neural density (reduction of acetylaspartate in DLPFC [dorsolateral prefrontal cortex]) Questionable volume reduction of amygdala Decrease in volume of ACC and hippocampus Hyperactive amygdala? 5-HT diminished in aggressive impulsivityy
ASPD 20% may be psychopaths Frontal regions in emotional tasks may function insufficiently (relatively speaking), even though there is increased activation Questionable volume of amygdala Affective memory tasks slow Decreased activity in amygdala, hippocampus, parahippocampus, ventral striatum, anterior-posterior cingulate gyrus
Fear-Anxiety Cluster C Top-down control of subcortical network responding to fear and connected with memory Larger ACC ↔ higher score of Harm- Avoidance (HC)
