Migraine & White Matter Hyperintensities

Recent high-quality research shows NO association between migraine and white matter hyperintensities
Multiple large-scale studies from 2023-2025 consistently show no association between migraine and white matter hyperintensities on brain MRI. These findings contradict older, smaller studies that suggested a possible connection between migraine and these specific brain imaging findings.

Evidence Against Migraine-White Matter Hyperintensity Association

The table below summarizes major research studies that found no association between migraine and white matter hyperintensities (small bright spots that can appear on brain MRI scans). These studies used advanced methodologies and large patient populations to provide reliable evidence.

Study & Year Study Type Number of Participants Key Finding What This Means
1000BRAINS Study
(2024)
View Study 		Long-term population study
3.7 years follow-up 		1,062 participants
(45% women, avg age 61)		 No increased white matter spots
No progression of white matter hyperintensities in migraine patients		 Migraine doesn't cause or worsen white matter hyperintensities over time
Northern Manhattan Study
(2023)
View Study 		Diverse community study
Multi-ethnic population 		546 participants
(65% Hispanic, avg age 71)		 No association found
No difference in white matter hyperintensities between migraine and non-migraine groups		 Results apply across different ethnic groups and older adults
Genetic Analysis Study
(2024)
View Study 		Mendelian randomization
Genetic approach 		589,356 participants
(Large genetic database)		 No causal relationship
Genetics show migraine doesn't cause white matter hyperintensities		 Strong evidence against migraine causing white matter hyperintensities
HUNT MRI Study
(Norway)
View Study 		Population-based imaging
Multiple assessment methods 		862 participants
(General population)		 No migraine association
While tension headaches showed connection, migraine did not		 Migraine is different from other headache types regarding white matter hyperintensities
Meta-Analysis Study
(2023)
View Study 		Systematic review & meta-analysis
Multiple studies analyzed 		Multiple cohorts
(Comprehensive review)		 Conflicting results across studies
Migraine characteristics found unrelated to white matter hyperintensities		 Large-scale analysis shows inconsistent evidence for any meaningful association
Migraine Subtype Study
(2021)
View Study 		Controlled comparison
No vascular risk factors 		92 migraine patients
24 controls		 No significant differences
No difference between migraine types or frequency		 Neither migraine severity nor type affects white matter hyperintensities
REFORM DTI Study
(2025)
View Study 		Cross-sectional case-control
Diffusion tensor imaging 		293 migraine patients
154 controls		 No significant differences
No differences in white matter microstructural integrity across all migraine subtypes		 Migraine does not result in microstructural alterations within cerebral white matter
UK Biobank Study
(2025)
View Study 		Large cross-sectional cohort
Middle-aged and older individuals 		3,431 migraine patients
26,969 controls		 Reduced white matter hyperintensities
Migraine associated with significantly decreased WMH burden, especially in under-65 age group		 Migraine may actually be protective against white matter hyperintensities in middle-aged individuals
Veterans TBI Study
(2024)
View Study 		Cross-sectional veteran cohort
Mild traumatic brain injury 		83 veterans
(67 with migraine-like headache)		 No association found
No relationship between migraine-like headache and white matter hyperintensities		 Even in TBI population, migraine-like headaches don't increase white matter hyperintensities
Clinical Implications: The current evidence does not support an association between migraine and white matter hyperintensities. If white matter hyperintensities are identified on brain imaging, they should not be attributed to migraine history. These findings are common in the general population and appear unrelated to migraine status.
Why This Matters: When WMHs are found on brain imaging, dismissing them as migraine-related may delay recognition of treatable vascular risk factors, early Alzheimer's disease pathology, cerebral amyloid angiopathy, or hereditary small vessel diseases. Proper evaluation of WMH patterns can guide targeted interventions, from blood pressure optimization to amyloid-modifying therapies, potentially improving patient outcomes through early, mechanism-specific treatment approaches.
