Stroke Risk Higher in Young Adults with Migraines, Other Factors
Updated June 01, 2025
Young adults under 50 face a significantly elevated risk of stroke from migraine with aura and other nontraditional stroke risk factors, according to research in the journal Stroke. The study highlights the increasing rate of cryptogenic strokes—those with no known cause—in this age group.
Jukka Putaala, head of the stroke unit at Helsinki University Hospital, emphasized the importance of assessing both traditional and nontraditional risk factors for effective stroke prevention in younger individuals. “Careful and routine assessment…is critical,” putaala said. He also advocated for thorough post-stroke screenings.
The research team analyzed data from over 1,000 adults aged 18-49 in Europe. half had experienced a cryptogenic ischemic stroke, while the other half had no stroke history. The study examined traditional risk factors (high blood pressure, smoking), nontraditional factors (blood clots, migraine with aura, chronic kidney disease), and female-specific factors (gestational diabetes, pregnancy complications).researchers also considered patent foramen ovale (PFO), a heart defect.
The analysis revealed that traditional risk factors were more strongly linked to stroke in individuals without a PFO. Conversely, nontraditional risk factors showed a stronger association with stroke in participants with a PFO.
Specifically, among those without a PFO, each additional traditional risk factor increased stroke risk by 41%, while each nontraditional risk factor increased it by 70%. Risk factors specific to women also independently increased stroke risk by 70%.
In participants with a PFO, traditional risk factors increased stroke risk by 18%. Though, after adjusting for demographics, nontraditional risk factors more than doubled the odds of an ischemic stroke.
The study also assessed population-attributable risk, which gauges the impact of eliminating a specific risk factor. For strokes without a PFO, traditional risk factors accounted for about 65% of cases, nontraditional factors for 27%, and female-specific factors for nearly 19%. In strokes linked to PFO, the contributions were 34%, 49%, and 22%, respectively.
“We were surprised by the role of non-traditional risk factors, especially migraine headaches, which seems to be one of the leading risk factors in the growth of strokes in younger adults,” Putaala said.
notably, migraine with aura emerged as a leading nontraditional risk factor, with a population-attributable risk of about 46% for strokes among people with a PFO and about 23% for those without.
Tracy E.Madsen, chair of the American Heart Association’s Clinical Cardiology/Stroke Women’s Health science Committee, noted the study’s value in presenting data by sex and age group. She highlighted the importance of recognizing migraine with aura and pregnancy complications as significant stroke risk contributors in younger women.
“This study is helpful as the authors present data by sex and age group…Recognizing specific risks that affect women and those not commonly seen,such as migraine with aura and pregnancy complications as significant contributors to stroke risk in younger women,could change our approach to screening for these risks and educating our patients throughout their lives,” Madsen said.
Limitations of the study include its observational nature and reliance on patient-reported risk factors. The predominantly white European descent of participants also limits the findings’ generalizability.
What’s next
Future research should focus on developing tailored risk assessment and management strategies,especially for young women with a history of migraine headaches and other nontraditional risk factors,to improve stroke prevention efforts.
