"What we discovered was that chronic morning headache was not only a manifestation of sleep apnea," said lead study author Maurice M. Ohayon, MD, PhD, the director of the Stanford Sleep Epidemiology Research Center. "This will affect the debate about chronic morning headache in terms of treatment."
Although depression and anxiety were the most commonly associated conditions, the researchers did find links to sleep disorders such as insomnia and sleep apnea. Chronic morning headache was also common among people with hypertension, musculoskeletal diseases, and those who took anti-anxiety drugs or had more than six alcoholic drinks a day.
"People with chronic morning headache must see a physician to be evaluated for anxiety and depression and other diseases," Dr. Ohayon said. "And physicians must think of depression and anxiety when they see people with this complaint. Many studies show that antidepressants will have an impact, so people no longer have to suffer from morning headaches."
