Key clinical point: Ketogenic diet (KD) significantly improved sleep complaints in patients with migraine, irrespective of migraine improvements and anthropometric modifications.
Major finding: Migraine intensity, headache frequency, and the severity of headache-related disability improved significantly after 3 months of KD therapy (all P < .001) along with a significant decrease in the rate of insomnia (before vs after treatment: 60% vs 40%; P < .001) and number of patients experiencing poor sleep (reduced to half at follow-up; P < .001). The modifications in sleep features showed no correlation with migraine improvements and anthropometric changes.
Study details: This study included 70 patients with migraine who received KD as a preventive therapy for migraine.
Disclosures: This study did not receive any funding. The authors declared no conflicts of interest.
