BACKGROUND AND PURPOSE: Parkinson disease (PD) is characterized by basal ganglia
abnormalities. However, there are neurodegenerative changes in PD that extend beyond …

Background and purpose This study employs magnetic resonance imaging (MRI) diffusion
tensor imaging to compare diffusion measures in the brains of patients with Parkinson's …

BACKGROUND AND PURPOSE: Diffusion tensor imaging (DTI) offers a unique window on
the connectivity changes, extending beyond the basal ganglia, which accompany the …

The spectrum of cognitive symptoms in Parkinson's disease (PD) can span various domains,
including executive function, language, attention, memory, and visuospatial skills. These …

BACKGROUND AND PURPOSE: Widespread cerebral changes are observed in advanced
stages of Parkinson disease (PD), suggesting that PD is a multisystem disorder. We …

Background Neuroimaging studies help us better understand the pathophysiology and
symptoms of Parkinson's disease (PD). In several of these studies, diffusion tensor imaging …

Objectives: We performed a systematic review to assess alterations in measures of diffusion
tensor imaging (DTI) in parkinsonian syndromes, exploring the potential role of DTI in …

Objective To investigate whether white matter microstructural changes can be used as a
predictor of worsening of motor features or cognitive decline in patients with Parkinson's …

The contribution of various brain areas to the overall progression of Parkinson's disease
remains to be determined. In this study, we apply MRI diffusion tensor imaging to investigate …

Objective To determine the differences in motor pathways and selected non-motor pathways
of the basal ganglia in Parkinson's disease (PD) patients compared to healthy controls …
