Migraine Without Aura

Description

Repeated, periodic attacks of one-sided throbbing headache made worse by activity and lasting 4-72 hours. The headache is accompanied by nausea, vomiting, photophobia, and/or phonophobia.

There is often an early warning phase involving mood swings, food cravings, excess energy, and cognitive impairment for several hours prior to the onset of headache. Once the headache has resolved, it is typically followed by several hours of fatigue, cognitive impairment, allodynia, and/or depressed mood.

Migraine is often thought of a severe headache. While this is true for many, not all migraine attacks involve severe pain. In fact, it is possible to experience ancephalgic (silent) migraine attacks in which there is no pain at all. It is the accompanying symptoms that distinguish migraine from other types of headache disorders.
