Hypnic headaches are benign primary headaches that affect the elderly, with an average age of onset at 63 ± 11 years.[1] They are moderate, throbbing, bilateral or unilateral headaches that wake the sufferer from sleep once or multiple times a night.[2] They typically begin a few hours after sleep begins and can last from 15–180 min.[3] There is normally no nausea, photophobia, phonophobia or autonomic symptoms associated with the headache. They commonly occur at the same time every night possibly linking the headaches with circadian rhythm, but polysomnography has recently revealed that the onset of hypnic headaches may be associated with REM sleep.[1]
