According to the National Institute of Health's National Institute on Neurological Disorders and Stroke, the pain of a migraine headache is often described as an intense pulsing or throbbing in one area of the head. The International Headache Society diagnoses migraine by pain level and number of attacks, and additional symptoms like nausea, vomiting, sensitivity to light and sound. More than 10 percent of people worldwide experience migraine, and it is thee times more common in women than men.
Chronic migraine is defined as a headache that occurs on 15 or more days per month for at least three months. According to the National Headache Foundation, studies have shown that nearly 80 percent of patients with chronic migraine have depression. Raising awareness of the prevalence of chronic migraine and exposing its extensive impact on productivity are critical to highlighting the need for more research in order to support the millions who suffer daily.
