Hypnic Headache in Childhood?: A Case Report

Hypnic headache is a rare, primary headache disorder of the elderly, initially described by Raskin in 1988 (1). Based on a series of reports over the past 16 years (1–19), the disorder was included in the 2004 Classification of Headache Disorders of the International Headache Society (IHS) (20). IHS criteria for hypnic headache require headaches of short duration which occur exclusively during sleep without autonomic accompaniments. The pain is generally dull in nature and regularly awakens sufferers during sleep. Though the overwhelming majority of cases occur in the elderly, to date the youngest reported age at onset of hypnic headache was 36 years (21). Herein, we report a 9-year-old fulfilling the diagnostic criteria for hypnic headache.
