Migraine headaches increase stroke risk

Nontraditional risk factors such as migraine and autoimmune diseases have a significantly greater effect on stroke risk in young adults than traditional risk factors such as hypertension, high cholesterol, and tobacco use, new research showed.

The findings may offer insight into the increased incidence of stroke in adults under age 45, which has more than doubled in the past 20 years in high-income countries, while incidence in those over 45 has decreased.

The findings were published online on March 26, 2024, in Circulation: Cardiovascular Quality and Outcomes.

Migraine, the most common nontraditional risk factor for stroke in this younger age group, was found in 20% of men (odds ratio [OR], 3.9) and 35% of women (OR, 3.3).

Other notable nontraditional risk factors included heart valve disease in both men and women (OR, 3.1 and OR, 4.2, respectively); renal failure in men (OR, 8.9); and autoimmune diseases in women (OR, 8.8).
