Causal relationships between alzheimer's disease genetics and brain connectivity alterations: a multi-modal mendelian randomization study with transcriptomic validation of 191 rs-fMRI and 635 DTI neuroimaging traits.

Abstract excerpt

Traditional observational magnetic resonance imaging (MRI) studies have revealed changes in brain connectivity in Alzheimer’s disease (AD). However, the findings have been inconsistent due to small sample sizes and potential confounding factors. The genetic effects of AD on the inherent brain activity and connectivity of patients are still not well understood. We utilized summary-level GWAS data for 223,906...
