Hypnic headache, a rare nocturnal headache disorder, affects individuals over 55. Lithium treatment showed significant improvement in a patient, suggesting a link to biological rhythm disturbances.

Area of Science:

  • Neurology
  • Sleep Medicine

Background:

  • Hypnic headache is a rare disorder causing nocturnal headaches that awaken patients.
  • It typically affects individuals over 55 and is linked to biological rhythm disturbances.

Observation:

  • A 70-year-old woman experienced intense, diffuse headaches upon waking for 12-14 months.
  • Headaches lasted 15-45 minutes, resolved spontaneously, and lacked associated autonomic or neurological symptoms.
  • Normal neurological exams and cranial CT were noted.

Findings:

  • Treatment with lithium resulted in a marked reduction in headache frequency.
  • This response supports the hypothesis that hypnic headache is related to biological pacemaker dysfunction.

Implications:

  • Hypnic headache, often termed 'alarm clock headache,' requires further investigation into its underlying biological mechanisms.
  • Lithium's efficacy suggests a potential therapeutic avenue for this unusual headache disorder.
