Answer

Attacks of cluster headache (CH) are typically short and occur with a clear periodicity, particularly during sleep or early morning hours, usually corresponding with onset of rapid eye movement (REM) sleep. [5, 9] Unlike migraine, CH is not preceded by aura and is not usually accompanied by symptoms such as nausea, vomiting, photophobia, or osmophobia. Typically, a patient experiences 1-2 cluster periods per year, each lasting 2 weeks to 3 months.
