Causal associations between hypertension and abnormal brain cortical structures: Insights from a bidirectional Mendelian randomization study
Year: 2024
Type: article
Study design: Observational Study
Abstract: Background: Observational studies suggest that hypertension affects brain cortical structure. However, the potential causal association has yet to be entirely determined. Thus, we aim to assess the causality between hypertension and abnormal cortical structure. Methods: We conducted a bidirectional Mendelian randomization (MR) study to estimate their relationship. Genome-wide association study summary statistics of hypertension (n = 484,598) and brain cortical (surface area and thickness) (n = 51,665) were derived from publicly available databases. Sensitivity analyses were applied to ensure the robustness of the results. Results: = 1.08E-06]. Moreover, we found several nominally associated gyri, including cuneus, isthmus cingulate, middle temporal, para hippocampal, posterior cingulate, superior temporal, and medial orbitofrontal, influence the incidence of hypertension. Conclusion: Our study showed causal relationships between hypertension and changes in specific brain cortical, providing new evidence for the heart-brain axis theory.
