Diffusion tensor imaging (DTI) allows measuring fractional anisotropy and similar
microstructural indices of the brain white matter. Lower than normal fractional anisotropy as …

Although the diagnosis of Parkinson's disease (PD) is essentially clinical, the
implementation of imaging techniques can improve diagnostic accuracy. While some …

Parkinson's disease (PD) and scans without evidence of dopaminergic deficit (SWEDD) are
two distinct neurological disorders that require different therapeutic approaches; therefore …

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 …

Parkinson's disease (PD) is a neurodegenerative disorder that predominantly affects the
motor system. Diffusion magnetic resonance imaging (MRI) has demonstrated deficits in …

Abstract Purpose of Review The substantia nigra pars compacta (SNc) and its projection to
the striatum undergo profound degeneration in Parkinson's disease (PD). Literature on …

Parkinson's disease (PD) is a progressive neurodegenerative disorder associated with both
underlying genetic factors and neuroimaging findings. Existing neuroimaging studies related …

Background A small proportion of patients with clinical parkinsonism have normal
transporter-single photon emission computed tomography (DaTSPECT) which is commonly …

Cognitive deficits are associated with poor quality of life and increased risk of development
of dementia in people with Parkinson's Disease (PD) with psychosis. However, the pattern of …

Parkinson's disease (PD), a progressive neurodegenerative disorder prevalent among the
elderly, requires a deeper understanding of brain structural changes for improved diagnosis …
