Headache is one of the most common neurological disorders. About 50% of the adult population suffer from headaches at least once per year, among those individuals, 30% or more reported migraine.
Up to 4% of all headaches are chronic (i.e. more than 15 days per month).
In 2013, the Global Burden of Disease Study found headache disorders to be the third highest cause worldwide of years lost to disability (YLD) with migraine (on its own) being sixth on the list.
Headache disorders have a significant impact on an individual’s personal and social life as well as employment and career aspirations. Headaches are commonly associated with co-morbid anxiety and depression which could in part be caused by pain and burden of the disorder.
