Area of Science:

  • Neurology
  • Psychiatry

Background:

  • Narcolepsy is a chronic neurological disorder affecting sleep-wake cycles.
  • Hypnagogic and hypnapompic hallucinations are common symptoms of narcolepsy.

Observation:

  • Two patients presented with complex, realistic, daytime sexual hallucinations.
  • These hallucinations led to significant personal and professional conflicts, including legal issues.

Findings:

  • Both patients were initially convinced of the hallucinations' reality.
  • Diagnostic evaluations, including sleep studies and HLA typing, confirmed narcolepsy.
  • The hallucinations were later recognized as non-psychotic by the patients.

Implications:

  • Undiagnosed narcolepsy with severe hallucinations may be misdiagnosed as psychosis.
