Abstract:
Hypnic headache is a rare short-lasting headache occurring exclusively during sleep in the elderly population. First described in 1988 by Raskin, this headache syndrome was adopted by the International Classification of Headache Disorders in 2004 within the "other primary headache" group (code 4.5).
