Background Approximately one third of recently diagnosed Parkinson's disease (PD)
patients experience cognitive decline. The nucleus basalis of Meynert (NBM) degenerates …

Abstract Cognitive impairment affects approximately 20%–50% of patients with Parkinson's
disease (PD), with a higher prevalence as the disease advances. The nucleus basalis of …

Currently, no reliable predictors of cognitive impairment in Parkinson's disease exist. We
hypothesized that microstructural changes at grey matter T1-weighted MRI and diffusion …

Background Cognitive impairment in Parkinson's disease (PD) involves the cholinergic
system and cholinergic neurons, especially the nucleus basalis of Meynert (NBM/Ch4) …

Objectives Cholinergic dysfunction plays a prominent role in cognitive impairment in
Parkinson's disease (PD). The aim of this study was to assess the relationship of baseline …

Objective A major contributor to dementia in Parkinson disease (PD) is degeneration of the
cholinergic basal forebrain. This study determined whether cholinergic nucleus 4 (Ch4) …

Abstract See Gratwicke and Foltynie (doi: 10.1093/brain/awx333) for a scientific commentary
on this article. Cognitive impairments are a prevalent and disabling non-motor complication …

Introduction We aimed to assess associations between multimodal neuroimaging measures
of cholinergic basal forebrain (CBF) integrity and cognition in Parkinson's disease (PD) …

Abstract Background and Purpose The circuitry underlying heterogenous cognitive profiles
in Parkinson's disease (PD) remains unclear. The purpose of this study is to investigate …
