I came across the following brief article in medscape;
AMSTERDAM — Patients with migraine, especially chronic migraine, are at increased risk for sleep disturbances, including sleep apnea (SA), a new study suggests.
About 37% of patients with migraine responding to a survey were deemed to be at high risk for SA, which is much higher than estimates in the general population.
And because over 75% of migraine respondents with SA were diagnosed by a physician, “it may be worthwhile to start asking our patients about this,” said Dawn C. Buse, PhD, a licensed clinical psychologist and associate professor, Department of Neurology, Albert Einstein College of Medicine of Yeshiva University, New York City.
“We haven’t tested this yet, but the hope is that if sleep apnea is associated with more frequent headaches, treating sleep apnea might benefit headache.”
Dr Buse, who is also director of behavioral medicine for the Montefiore Headache Center in New York City, presented the new results from the Chronic Migraine Epidemiology and Outcomes (CaMEO) study at the Congress of the European Academy of Neurology (EAN) 2017.
Both depression and anxiety have a bidirectional relationship with migraine, Dr Buse told delegates. Such a relationship also exists in sleep disorders; sleep disorders can aggravate migraine and migraines can worsen sleep disorders.
Researchers recruited participants from an online panel by using quota sampling. Survey invitations were sent to 16,763 CaMEO study respondents, of whom 12,810 provided valid data.
Richard Katesmark comments; Anyone who works with headache & migraine will know that sleep problems ofter coexist. Identifying as association between breathing issues at night ( which effect sleep quality ) & migraine is therefore no real surprise. Here at our surrey headache & migraine centres sleep issues are always looked into and addressed.
