Diffusion tensor image analysis along the perivascular space (DTI-ALPS) in Parkinson's disease patients with subjective cognitive decline

Introduction

This study aimed to examine diffusion alterations indexed by the diffusion tensor image analysis along the perivascular space (DTI-ALPS) in patients with Parkinson's disease presenting with subjective cognitive decline (PD-SCD), and to investigate their associations with impairments across specific cognitive domains.
