Background:
Given inconsistent evidence regarding the migraine-Alzheimer's disease association, this Mendelian randomization (MR) study examines their potential causal relationship.
Methods:
GWAS summary statistics for migraine and Alzheimer's disease were acquired from the IEU Open GWAS repository. We implemented a multi-stage MR framework comprising (1) univariate analysis, (2) independent replication, (3) multivariable MR, (4) meta-analysis to evaluate migraine-AD causality.
Results:
Univariate results showed OR = 13.43, 95% CI: 2.86-63.16, P < 0.01; replication Mendelian randomization results were OR = 12.64, 2.89-55.38, P < 0.01 with OR = 1.13, 95% CI: 1.06-1.21, P < 0.01, meta-analysis results were OR = 1.14, 95% CI: 1.07- 1.22, P < 0.01. Multivariate Mendelian randomization results were OR = 18.90, 95% CI: 1.69-210.88, P < 0.01.
Conclusion:
Considering the observed epidemiological correlations and shared pathophysiological mechanisms between migraine and Alzheimer's disease (AD), we propose that chronic migraine may increase the susceptibility to AD through complex biological interactions. This hypothesis is reinforced by our Mendelian randomization (MR) findings, which support a causal relationship. Therefore, early and effective intervention in migraine management could serve as a promising strategy to mitigate the future risk of AD onset.
Insights
This study suggests a causal link between migraine and Alzheimer's disease (AD). Effective migraine management may reduce the risk of developing AD.
Area of Science:
- Neuroscience
- Genetics
- Epidemiology
Background:
- The association between migraine and Alzheimer's disease (AD) lacks consistent evidence.
- Migraine and AD share potential pathophysiological mechanisms.
Purpose of the Study:
- To investigate the potential causal relationship between migraine and Alzheimer's disease using Mendelian randomization (MR).
Main Methods:
- Utilized GWAS summary statistics for migraine and AD from the IEU Open GWAS repository.
- Implemented a multi-stage MR framework: univariate analysis, independent replication, multivariable MR, and meta-analysis.
Main Results:
- Mendelian randomization analyses indicated a significant association between migraine and increased Alzheimer's disease risk (e.g., OR = 1.14, 95% CI: 1.07-1.22).
- Multivariable MR results further supported a causal link (OR = 18.90, 95% CI: 1.69-210.88).
Conclusions:
- Findings support a causal relationship where chronic migraine may increase susceptibility to Alzheimer's disease.
- Early and effective migraine management could be a strategy to mitigate future AD risk.
