Both headache and sleep disturbance are common symptoms in clinical practice. When considering the relationship between headache and sleep disturbance, chronic daily headache, especially morning headache, is an indicator of nonspecific sleep disturbance.
The relationship between sleep and headache is classified as follows : sleep–triggered or sleep–related headaches, sleep duration induced headache, sleep phase–related headaches, sleep–relieved headaches, dreams and headache and effects of headaches on sleep (Jennum & Jensen, 2002).
Primary sleep disorders such as narcolepsy, parasomnia, restless legs syndrome may coexist in patients with migraine. Cluster headache suggests association with obstructive sleep apnea. Morning headache is important as a symptom of sleep apnea headache.
Headache and sleep disorders are interrelated, both of which can adversely affect the quality of life of patients. Therefore, clinicians need to recognize the pathophysiology and interrelationship of headache and sleep disorders, respectively, and to evaluate and treat headache and sleep disorders properly.
