⚡Cluster headache is considered one of the most painful conditions known.
⏰The typical picture is unilateral headache attacks lasting 15 to 180 minutes, associated with cranial autonomic symptoms, parasympathetic hyperactivity and sympathetic hypo-activity.
🌦️Triggers for cluster attacks include alcohol, strong smells, sleep, circadian disruption, and weather changes.
🥵 Cranial autonomic features include ptosis, conjunctival injection, lacrimation, rhinorrhoea, nasal stuffiness, eyelid and facial swelling, aural fullness, facial sweating, and redness.
👬This is one of the few primary headaches that predominantly affects men, with a male-to-female ratio of approximately 2.5:1.
