CHRONIC PAROXYSMAL HEMICRANIA Meaning and
Definition
-
Chronic Paroxysmal Hemicrania (CPH) is a medical condition characterized by recurring episodes of severe, debilitating headaches. It is classified as a primary headache disorder and falls under the category of trigeminal autonomic cephalalgias. CPH is relatively rare, with prevalence rates estimated to be less than 1% in the general population.
The defining feature of CPH is the presence of unilateral, short-lasting headache attacks, usually occurring multiple times throughout the day. These attacks typically last from a few minutes to a couple of hours and are accompanied by intense pain on one side of the head, usually around the temple or eye area. Individuals with CPH may also experience autonomic symptoms ipsilateral to the headache, such as tearing, nasal congestion, and eyelid swelling.
Unlike some other headache conditions, CPH exhibits a strict response to indomethacin, a nonsteroidal anti-inflammatory drug. If a patient experiences a significant reduction in headache frequency and intensity with indomethacin, it is highly suggestive of CPH diagnosis. However, it is important to exclude secondary causes of headache before initiating treatment.
While the exact cause of CPH remains unknown, it is believed to involve an abnormal activation of the trigeminal autonomic reflex, which leads to the characteristic symptoms. Treatment for CPH often involves a daily regimen of indomethacin to prevent or reduce the frequency and severity of attacks. In cases where indomethacin is not tolerated or ineffective, other medications such as verapamil or topiramate may be prescribed.
