Robert Shapiro, a professor of neurology, says that while cluster headaches are about as common as multiple sclerosis with a similar disability level, as of 2013, the US National Institutes of Health had spent $1.872 billion on research into multiple sclerosis in one decade, but less than $2 million on cluster headache research in 25 years.

CPH occurs roughly in 1 in 50,000 people, while cluster headaches are comparatively more common and are found in 1 in 1000 people. [5] Cluster headaches occur primarily in men, while CPH is more commonly diagnosed in women. [6] The female to male ratio of diagnosed patients can range anywhere from 1.6:1 to 2.36:1. [5]
Cluster headaches are a rare type of headache that cause bursts of intense pain around the eye. Each burst lasts about 15 minutes, but an attack can last between one and three hours.
More women than men experience migraines. In Europe and North America, 5–9% of men experience migraines, while 12–25% of women experience migraines. [78] Cluster headaches are relatively uncommon. They affect only 1–3 per thousand people in the world. Cluster headaches affect approximately three times as many men as women. [79]
Headaches disorders are surprisingly common. Experts discuss new research and why women typically have more headaches — including migraine attacks — than men.
Lilly's (LLY) CGRP antibody, Emgality, becomes the first and only medicine approved to treat episodic cluster headache in adults.
The factor that allows hemicrania continua and its exacerbations to be differentiated from migraine and cluster headache is that hemicrania continua is characterized by complete response to therapeutic doses (25–300 mg) of indomethacin. The positive response to this drug is, in fact, a fundamental sine qua non criterion used in differential ...
After migraine, the most common type of vascular headache is the "toxic" headache produced by fever. Other kinds of vascular headaches include cluster headaches , which are very severe recurrent short lasting headaches, often located through or around either eye and often wake the patients up at the same time every night.
