Moyamoya Disease and the Risk of Parkinson's Disease.

ABSTRACT:

Objectives

Moyamoya disease (MMD) is a rare cerebrovascular disorder characterized by the progressive narrowing of arteries at the base of the brain, forming abnormal collateral vascular networks. While vascular parkinsonism is noted in MMD, its link to Parkinson's disease (PD) has not been explored. We aimed to determine whether the risk of PD is increased in patients with MMD and to identify the potential role of the RNF213 gene.

Methods

We report two cases of PD with a history of MMD associated with the Arg4810Lys variant of RNF213. Using the Korean National Health Insurance Service database, we studied the association between MMD and subsequent PD risk using Cox proportional hazards regression analysis. Moreover, we explored the interaction between α-synuclein and RNF213
