worried woman doing finances(BlackDoctor.org) — Families with at least one person suffering from migraines spend about 70 percent more each year on medical costs than other families, according to a new study.

Most of these costs pile up at the pharmacy counter or in outpatient care, according to Paul Stang, Ph.D., of Galt Associates Inc. and colleagues, writing in the American Journal of Managed Care.

Even family members without migraines have higher medical costs when they live with a migraine sufferer, suggesting that the illness contributes to overall unhealthy stress levels in the household.

“The results suggest that migraine, even under treatment, is associated with a substantial impact on the health care costs for other families individually and as a unit,” Stang says.

The differences in cost remained the same even after taking into account other health conditions that might have affected migraine patients, Stang added.
