Parkinson's disease and Alzheimer's disease: a Mendelian randomization study.

ABSTRACT:

Background

Alzheimer's disease (AD) and Parkinson's disease (PD) are the top two common neurodegenerative diseases in elderly. Recent studies found the α-synuclein have a key role in AD. Although many clinical and pathological features between AD and PD are shared, the genetic association between them remains unclear, especially whether α-synuclein in PD genetically alters AD risk.

Results

We did not obtain any significant result (OR = 0.918, 95% CI: 0.782-1.076, P = 0.291) in MR analysis between PD and AD risk. In MR between α-synuclein in PD with AD risk, we only extracted rs356182 as the IV through a strict screening process. The result indicated a significant association based on IVW method (OR = 0.638, 95% CI: 0.485-0.838, P = 1.20E-03). In order to examine the robustne
