We explored the relationship between narcolepsy and different types of head
aches. We interviewed 68 patients with idiopathic narcolepsy for the presen
ce of headache symptoms based on the criteria of the International Headache
Society (IHS). Eighty-one percent of the patients reported headaches that
warranted an IHS headache diagnosis. Fifty-four percent of the patients (64
% women, 35% men) had migraine with all IHS criteria fulfilled.
