TL;DR: A novel bi-tensor diffusion analysis model was used to indicate that all forms of parkinsonism had elevated free-water in the substantia nigra, and both multiple system atrophy and progressive supranuclear palsy, but not Parkinson's disease, showed a broad network of elevatedFree-water and altered free- water corrected fractional anisotropy that included the basal ganglia, thalamus, and cerebellum.

TL;DR: Significant differences in brain activity were observed between essential tremor and Parkinson's disease, and functional connectivity analyses during the task evidenced reduced cerebellar-cortical functional connectivity in patients withessential tremor compared with controls and Parkinson’s disease.

TL;DR: Results provide the first evidence that fMRI activation is abnormal in the basal ganglia, cerebellum, and cerebrum in MSAp, and that a key distinguishing feature between MSA p and PD is the extensive and widespread volume loss throughout the brain in M SAp.

TL;DR: Findings show widespread changes in functional brain activity in CD and most importantly that dystonic symptoms relate to disrupted activity in the somatosensory cortex and cerebellum.

TL;DR: It is found that PSP and PD share reduced functional activity of the basal ganglia and cortical motor areas, but this is more pronounced in PSP than in PD.
