A new study published in JAMA Network Open suggests that a relatively healthy cardiovascular system may actually increase the likelihood of experiencing migraines. Researchers found that individuals with lower cardiovascular risk scores were more prone to developing or having active migraines, a finding that was particularly significant for women.
Migraine is a disabling neurological disorder, often accompanied by nausea, vomiting, and heightened sensitivity to light and sound. It is especially prevalent among women under 50, who represent the largest group affected by this condition. The study’s findings shed new light on the complex relationship between vascular health and migraine occurrence.
Cardiovascular Health and Migraine Link
Led by researchers from the Netherlands, the study explored the connection between cardiovascular health and migraine activity in a large cohort of 140,915 participants. The data indicated that as cardiovascular risk scores, based on the Systematic Coronary Risk Evaluation 2 (SCORE2) system, increased, the likelihood of experiencing prevalent or incident migraines decreased. The analysis also showed that women with migraine had a lower cardiovascular risk than their male counterparts.
Specifically, the research revealed that among the participants, the prevalence of migraine dropped significantly as cardiovascular risk increased, suggesting that individuals with healthier vascular systems might be more susceptible to developing migraines. The odds of developing a new migraine also decreased with higher cardiovascular risk scores.
Findings and Gender Differences
Although both men and women were found to have a similar association between cardiovascular risk and migraine status, the link was notably stronger among women. The researchers emphasized that this relationship was not solely due to age, confirming that vascular health might play a significant role in the development of migraines, especially in women.
Previous studies had suggested that women with higher cardiovascular disease (CVD) risk might have a lower likelihood of active migraines. However, the present study challenges that idea by showing an inverse relationship between migraine occurrence and lower cardiovascular risk, particularly for women.
Understanding the Broader Implications
The findings highlight the need for further investigation into the dual impact of both cardiovascular and migraine health, with an emphasis on the female population. Migraines and cardiovascular disease (CVD) often share common risk factors, and both are major health concerns, particularly among women. In the U.S., over 60 million women are living with CVD, a population that also faces higher migraine prevalence.
The study suggests that despite migraine being a significant marker for cardiovascular risk, a healthier vascular system may increase vulnerability to migraines. The research concludes that traditional cardiovascular risk assessments, such as SCORE2, may not fully account for the complex relationship between these two conditions.
As further studies are planned, researchers stress that women should remain a primary focus when exploring the intersection of cardiovascular health and migraines. These findings open new avenues for understanding how the two health issues might be linked and the potential for developing more effective treatments.
In Conclusion
This study provides fresh insights into the relationship between cardiovascular health and migraine occurrence, particularly for women. The complex interplay between these two factors underscores the need for more targeted research to better understand their association and to improve treatment options for those affected by both conditions.
