chronic, in which persons experience attacks on a daily basis for a year or more, and episodic, in which the headaches do not occur for months or years.
Paroxysmal hemicrania (PH) is a rare form of headache. Paroxysmal hemicrania usually begins in adulthood, and affected persons experience severe throbbing, claw-like, or boring pain .
Chronic paroxysmal hemicrania (CPH) is also known as Sjaastad syndrome
Episodic paroxysmal hemicrania occurs in both sexes, with a slight female preponderance (1.3:1). The age of onset is variable; studies show EPH onset is 12-51 years.
Episodic paroxysmal hemicrania (EPH), a more rare form of the disorder, is characterized by bouts of frequent, daily attacks with the same clinical features of CPH, but separated by relatively long periods without headache.
The main feature of chronic paroxysmal hemicrania is frequent attacks of strictly one-sided severe pain localized in or around the eye or temple regions, lasting from 2-45 minutes in duration, and occurring 2-40 times per day.
Episodic paroxysmal hemicrania involves attacks of severe pain in the eye or temple area that last about one to 30 minutes, with a frequency of three or more events per day, and clear intervals between bouts of attacks that may last from months to years.
A neurologist is the primary consultant for PH treatment. An ophthalmologist is also important to evaluate any eye disorders such as glaucoma.
Chronic PH involves headaches that are one-sided, severe, affecting the eye or temple area, and lasting two to 45 minutes, occurring more than five times per day.
The nonsteroidal anti-inflammatory drug (NSAID) indomethacin often provides complete relief from symptoms. Other less effective NSAIDs, calcium-channel blocking drugs (such as verapamil), and corticosteroids may be used to treat the disorder.
