Parkinson's disease (PD) is a heterogeneous neurological disorder with a variety of motor
and non-motor symptoms. The underlying mechanisms of these symptoms are not fully …

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

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 …

Diffusion tensor imaging (DTI) of the substantia nigra has shown promise in detecting and
quantifying neurodegeneration in Parkinson disease (PD). It remains unknown, however …

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

Differentiating Parkinson's disease (PD) from other types of neurodegenerative atypical
parkinsonism (AP) can be challenging, especially in early disease stages. Routine brain …

Parkinson disease (PD) can be considered as a brain multisystemic disease arising from
dysfunction in several neural networks. The principal aim of this study was to assess …

Background Gait impairments are common in Parkinson's Disease (PD) and are likely
caused by degeneration in multiple brain circuits, including the basal ganglia, thalamus and …

Diffusion tensor imaging (DTI) findings from emerging studies of cortical white-matter
integrity in Parkinson's disease (PD) without dementia are inconclusive. When white-matter …
