People who get migraines are more likely to have depression than people who don't get migraines, according to a new study in the journal Headache.
And the findings also suggest that people with depression have a higher risk of migraine, Reuters reported, though a cause-and-effect relationship can't yet be teased out from the findings.
Regardless, the results show that "something is going on here," study researcher Geeta Modgill, who worked at the University of Calgary while conducting the research, told Reuters.
The research involved health data from 15,254 people who participated in the Canadian National Population Health Survey, and who were followed up biennially for 12 years, Medical News Today reported.
Researchers found that the people who suffered from migraines had a 60 percent increased risk of depression, compared with people who don't have migraines, and that people with depression have a 40 percent increased risk of having migraines, compared with people who don't have depression, according to Medical News Today.
The finding comes on the heels of past research suggesting that migraines and depression are genetically linked, TIME reported on a 2010 Neurology study suggesting that people with migraines may be genetically predisposed to have depressive symptoms.
Migraines are common, with 18 percent of American women and 6 percent of American men experiencing migraine, according to the Migraine Research Foundation.
A migraine is a severe type of headache that has symptoms including throbbing head pain, light sensitivity, nausea and even vomiting. Some people get an aura, which is a vision disturbance, before the migraine occurs, according to the National Institutes of Health.
