Migraine and vascular disease biomarkers: A population-based case-control study

Area of Science:

• Neurology
• Vascular Biology
• Epidemiology

Background:

• The link between migraine and stroke is not fully understood, with endothelial activation proposed as a mechanism.
• This study investigates the association between migraine and vascular disease biomarkers in a community setting.

Purpose of the Study:

• To evaluate the association of migraine (with and without aura) with specific vascular biomarkers.
• To explore potential sex differences in these associations.
• To determine if aura characteristics (duration, frequency) correlate with biomarker levels.

Main Methods:

• The study involved 300 women and 117 men aged 30-60 from the Dutch CAMERA 1 study.
• Participants included those with migraine with aura (MA), migraine without aura (MO), and headache-free controls.
• Plasma levels of fibrinogen, Factor II, D-dimer, hs-CRP, and von Willebrand factor antigen were measured and compared between groups.

Main Results:

• Migraineurs showed elevated levels of fibrinogen and hs-CRP compared to controls.
• Migraine with aura (MA) and migraine without aura (MO) were associated with higher fibrinogen; MA was also linked to higher Factor II and hs-CRP.
• Elevated fibrinogen and Factor II were observed in women with MA but not men.
• In migraineurs, years and number of aura attacks, but not headache, predicted elevated biomarker levels.

Conclusions:

• Elevated vascular biomarkers are associated with migraine, particularly MA.
• The duration and frequency of aura attacks are linked to increased levels of vascular biomarkers.
• Findings suggest a potential role for vascular mechanisms, including endothelial activation, in migraine pathophysiology.
