ETIOLOGY
GENETIC FACTOR:
Cluster A personality disorders are more common in the
biological relatives of patients with schizophrenia than in
control groups
Antisocial personality disorder is associated with alcohol use
disorders
Depression is common in the family backgrounds of patients
with borderline personality disorder
A strong association is found between histrionic personality
disorder and somatization disorder
Patients with avoidant personality disorder often have high
anxiety levels
Patients with obsessive-compulsive personality disorder show
some signs associated with depression
BIOLOGICAL FACTORS:
Persons who exhibit impulsive traits also often show high levels of
testosterone, 17-estradiol, and estrone.
Low platelet MAO levels associated with more social activity.
Levels of 5-hydroxyindoleacetic acid (5-HIAA), a metabolite of
serotonin, are low in persons who attempt suicide and in patients
who are impulsive and aggressive.
 Slow-wave activity on EEGs in antisocial and borderline.
PSYCHODYNIMIC FACTORS:
Freudian explanations of arrested development at oral, anal,
and genital stages leading to dependent, obsessional, and
histrionic personalities; borderline personality organization.

primitive defense mechanisms such as splitting and
projective identification.
