A study that has followed the health of over 13,000 people since 1994 concludes that people with migraine have a higher chance of experiencing a major depressive episode in their lifetime than people without migraine. The Canadian study collected health information about the subjects every two years, including the presence of migraine and/or major depression.
Just over 7,000 participants had never had a major depressive incident when the study began. After 12 years of follow-up data, the researchers found the incidence of major depressive episodes amongst all these participants was 14.8%. But for migraineurs, the incidence was 22.2%.
“Migraine may contribute to the development of major depressive episodes or these two conditions may have shared causal determinants,” said Geeta Modgill from the Department of Community Health Sciences, University of Calgary. “Development of specialized interventions and services for this population may be warranted.”
