CPAP therapy for obstructive sleep apnea may improve migraines

I often get referrals from headache specialists because they know that sleep disorders and headaches often exist together. In particular, obstructive sleep apnea (OSA) has been associated with headache upon awakening. But any sleep disorder that breaks up sleep could increase risk of regular headaches. This article describes a study showing that CPAP use may improve migraines. In particular, regular CPAP use for OSA decreased the frequency of migraine attacks, their duration, and intensity. CPAP also lowered medication use and lost days from work.
