Findings raise questions about migraine and sleep


 

AT SLEEP 2022

More questions than answers

Commenting on the study, Donald Bliwise, PhD, professor of neurology at Emory Sleep Center, Atlanta, said the study findings shouldn’t change how clinicians approach migraine in relation to sleep.

“It’s a case series, it’s retrospective,” said Dr. Bliwise, who was not involved in the study. “It’s the largest study that I know of that has ever looked at the diagnosis of migraine in relation to polysomnographic measures of sleep, but it’s imprecise to the extent that migraine is a clinical diagnosis, so not everyone that carries the diagnosis of migraine has the diagnosis made by a neurologist.”

The study raises more questions than it answers, he said, “but that’s not necessarily a bad thing. I think we need more prospective studies.” Those studies should be more granular in how they analyze sleep in migraine patients “Since migraine is an intermittent event, and sleep quality and length, and percentage of REM sleep and even sleep apnea can vary from night to night, it would be fascinating to look at headaches over a month in relation to sleep over a month.”

Dr. Gruenthal and Dr. Bliwise have no disclosures. The Association of Migraine Disorders provided funding for the study.
