Obsessive Compulsive Disorder Disease

BASICS

DESCRIPTION
Psychiatric condition classified as an anxiety disorder in Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) and characterized by recurrent, intrusive thoughts (obsessions) and ritualistic behaviors (compulsions)
  • Obsessions and compulsions consume more than an hour per day and cause occupational/social impairment
  • Patients know thoughts (obsessions) come from their own minds and are not imposed from outside (as in thought insertion). Thoughts are not associated with another disorder (for example, thought of food if an eating disorder is present).
  • Compulsions are ritualistic behaviors designed to relieve the anxiety of obsessions
  • Common obsessive themes:
    • Violence, such as harming a beloved child
    • Doubt, such as whether doors or windows locked or iron turned off
    • Blasphemous thoughts, such as in a devoutly religious person
    • Contamination, dirt or disease
    • Symmetry or orderliness
  • Common rituals or compulsions:
    • Hand washing
    • Checking
    • Counting
    • Hoarding
    • Repeaters - such as dressing rituals
  • System(s) affected: Nervous
  • Genetics: Positive family history in about 20% of cases, no mode of transmission identified
  • Incidence/Prevalence in USA: 2.5% lifetime prevalence, 1.5-2.1% one year prevalence
  • Predominant age: Mean age 20. 1/3 cases present by age 15, new cases after age 50 rare, 80% of cases before age 35
  • Predominant sex: Male = Female (males tend to present at a younger age)
SIGNS AND SYMPTOMS
  • Obsessions and/or compulsions that consume more than an hour a day and cause significant distress or impairment
  • Obsessions (thoughts) are recurrent; patient attempts to ignore or neutralize thoughts with another thought or action
  • Neither obsessions nor compulsions are related to another mental disorder
  • Compulsions (actions) are repetitive, purposeful behaviors in response to thoughts in attempt to neutralize the thought – such as checking in response to doubt (locks, doors, windows, or driving back over a route to check for any possible damage inadvertently done while driving one’s car)
  • Repeated handwashing or ritualistic handwashing in response to fear of contamination
  • 80–90% of patients have obsessions and compulsions
  • 10–19% are pure obsessional
  • 5% perform rituals until they “feel right” and may not have an identifiable obsession
CAUSES
Dysregulation of neurotransmitter, serotonin
RISK FACTORS
Greater concordance in monozygotic twins family history as above
