The pathophysiology of Parkinson's disease tremor
2022, Journal of the Neurological SciencesCitation Excerpt :First, early PET studies show that VIM-DBS which resulted in PD tremor suppression was associated with decreased blood flow in the contralateral cerebellum [77] and ipsilateral sensorimotor cortex [77,78]. Furthermore, it was shown that PD tremor is covariant with regional hypermetabolism in a network consisting of cerebellum, thalamus (VLp) and motor cortex [79], Finally, FDG-PET of tremor-dominant PD patients showed tremor-related activity of the putamen and a cerebello-thalamo-cortical network, which was reduced after VIM-DBS [80]. In addition, structural MRI studies using voxel-based morphometry show that tremor-dominant PD patients have reduced grey matter volume in the cerebellum [81] and increased grey matter in the posterior VL of the thalamus [82].
Altered thalamic glucose metabolism in cerebellar projections in Parkinson's disease
2018, Basal GangliaCitation Excerpt :One key finding in this context is the bilateral appearance of the metabolic increase. In this regard, the study of Kassubek et al. [5] solely studied 8 patients, whereas we included 27 parkinsonian patients in the study, which might have led to a higher statistical power. Next to the missing sub-scores, also the neuropsychological data, which were not available, might have implications onto the metabolic rates in the individual patients and should be integrated in future studies.
