Background
The change of microvascular function over the course of Parkinson's disease (PD) remains unclear.
Objective
We aimed to ascertain regional cerebrovascular reactivity (CVR) changes in the patients with PD at baseline (V0) and during a 2‐year follow‐up period (V1). We further investigated whether alterations in CVR were linked to cognitive decline and brain functional connectivity (FC)...
Background
Cerebrovascular dysfunction in Parkinson's disease (PD) is heterogeneous and may contribute to disease pathophysiology or progression. There is a need to understand the mechanisms by which cerebrovascular dysfunction is altered in participants with PD.
Objectives
The objective of this study is to test the hypothesis that participants with PD exhibit a significant reduction in the ability...
