Pathological laughter in an adolescent girl was identified as an obsessive-compulsive phenomenon, not a psychotic disorder. Treatment with medication and therapy led to significant improvement.

Area of Science:

  • Psychiatry
  • Neuroscience
  • Clinical Psychology

Background:

  • Pathological laughter is typically associated with organic and functional psychotic disorders.
  • Its significance in other psychiatric conditions has been largely overlooked.
  • This case explores pathological laughter in a different clinical context.

Observation:

  • A case report details an adolescent girl presenting with pathological laughter.
  • The laughter was characterized as irrational and ego-dystonic, with resistance to the symptom.

Findings:

  • The patient's condition may be linked to a family history of obsessive-compulsive disorder, paternal smiling habits, and personal history of trauma and abuse.
  • Selective serotonin reuptake inhibitors and behavioral therapy resulted in positive outcomes.

Implications:

  • Pathological laughter can manifest as an obsessive-compulsive phenomenon.
  • Detailed assessment is crucial to avoid misdiagnosing pathological laughter as a psychotic disorder.
