    their surroundings, and reality, experience, and
    identity may disintegrate
  • Historically, both somatoform and dissociative
    disorders used to be categorized as hysterical
    neurosis
  • in psychoanalytic theory neurotic disorders
    result from underlying unconscious conflicts,
    anxiety that resulted from those conflicts and
    ego defense mechanisms

Somatoform Disorders
  • Somatization disorder
  • Briquets syndrome (100 years ago)
  • patients have a history of many physical
    complaints that can not be explained by a medical
    condition, the complaints are not intentionally
    produced
  • 20 of patients in primary care setting
  • develops during adolescence (majority women)
  • may be connected to Antisocial personality
    disorder
  • difficult to treat (reassurance, stress
    reduction, more adoptive methods of interacting
    with family are encouraged)

7
Somatoform Disorders
  • Conversion Disorder

    conversion, and primary/secondary gain
  • Detachment from the trauma and negative
    reinforcement seem critical
  • Different from factitious disorder (intentional)
