Sleep and cluster headache: is circadian rhythm a cause?

Takeaway

  • Quality of sleep is compromised in individuals with episodic and chronic cluster headache (ECH/CCH), potentially because onset tends to occur in the early hours of the morning.

  • People with CCH find it difficult to adjust sleep patterns, while those with ECH are less able to cope with decreased sleep duration.

Why this matters

  • Clinicians should advise people with episodic and chronic migraine to adhere to individualized, regimented sleep schedules as it may help to prevent headache.
