Migraine is a chronic neurological disorder characterized by recurrent attacks of moderate to severe headache. A migraine headache has a throbbing or pulsating pain, usually on only one side of the head or unilateral lasting from 2 to 72 hours. Symptoms that are associated with this kind of headache are nausea, vomiting, and extreme sensitivity to light (photophobia) and sound (phonophobia). Migraine headaches, which are often misdiagnosed as sinus or tension headaches, are severe enough to interfere with sleep, work, and other everyday activities. They may occur as often as several times per week or as rarely as once or twice a year.
Most people with migraine headaches perceive a transient visual, sensory, language, or motor disturbance which signals that the headache will soon occur which is called an aura, but sometimes they feel the aura but won't have a migraine.
Approximately 30 million people in the US are suffering from migraine. Though it can affect teens and kids, it is most common among people with the age range of 25 to 55. Women are more prevalent to have migraine than men.
