New Studies: CPAP for Sleep Apnea and Obesity Interventions Ease Migraine
When used regularly (87 percent of the time), CPAP not only reduced apnea episodes and improved overall sleep quality, but also resulted in fewer migraines over the study period, In another study, investigators reported that six months after bariatric surgery, the mean number of headache days per month fell from 11 to 6.7, pain severity was reduced, and the number of patients reporting moderate-to-severe disability decreased from 50 percent before surgery to 12.5 percent after surgery.
Two new studies offer preliminary evidence supporting interventional approaches for migraine. In one, continuous positive airway pressure therapy, an increasingly common treatment for sleep apnea, appeared to reduce migraine symptoms in some patients, Swiss researchers reported. In another, a US research team found that severely obese patients with migraines who underwent gastric bypass or banding surgery had fewer and less severe episodes.
Although encouraging, both studies, which were published in the Mar. 29 issue of Neurology, involved small groups of patients. Larger trials are needed to corroborate the findings, the researchers said.
