What are the characteristics of the paroxysm?

Answer 1

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.

Answer 2

A paroxysm is a sudden onset or intensification of symptoms or a disease, often accompanied by a sharp and distinct peak in severity. It is typically short-lived and may recur intermittently. Paroxysms can vary in nature depending on the underlying condition, such as in the case of paroxysmal pain, coughing, or neurological symptoms.
