Background The objectives of this study were to investigate progressive cortical thinning and
volume loss in Parkinson's disease (PD) patients with different longitudinal patterns of …

The aim of this study was to investigate patterns of cortical atrophy associated with mild
cognitive impairment in a large sample of nondemented Parkinson's disease (PD) patients …

Dementia is a frequent and disabling complication of Parkinson's disease (PD). Clinicians
and researchers lack a biomarker capable of tracking the structural and functional changes …

The aim of this study was to investigate the progression of cortical thinning and gray‐matter
(GM) volume loss in early Parkinson's disease (PD). MRI and neuropsychological …

Background Clinical variability in the Parkinson's disease phenotype suggests the existence
of disease subtypes. We investigated whether distinct anatomical patterns of atrophy can be …

Background Cortical neural correlates of ongoing cognitive decline in Parkinson's disease
(PD) have been suggested; however, the role of subcortical structures in longitudinal …

Background: Cognitive dysfunction is common in Parkinson's disease (PD), and along with
PD with dementia (PDD), the concept of mild cognitive impairment in PD (PD‐MCI) has been …

ABSTRACT A challenge in Parkinson's disease (PD) is to identify biomarkers of early
cognitive change because functioning in some domains may be more prognostic of …

Background Brain structure abnormalities throughout the course of Parkinson's disease
have yet to be fully elucidated. Objective Using a multicenter approach and harmonized …

Background The aim of this work was to investigate the cortical and white matter changes
that underlie cognitive impairment in patients with incident Parkinson's disease (PD) disease …
