Longitudinal Tracking of Patients Diagnosed With Neurodegenerative Movement Disorders
Study Details
Study Description
Brief Summary
The purpose of this protocol is to create an active natural history cohort of patients with degenerative movement disorders, tracked in a clinical setting with clinical rating scales and neuroimaging. The overarching rationale is that neurodegenerative diseases may be heterogeneous, complex disorders. A new way of performing clinical trials in these patients may be in order and this protocol aims to build a longitudinally tracked clinical trial-ready cohort of patients. The purpose of this protocol is to establish an active natural history cohort of patients with neurodegenerative movement disorders who are deeply phenotyped and "clinical trial ready" across Mass General Brigham.
After a thorough clinical diagnostic evaluation (this may include clinically indicated testing, for example MRI, FDG-PET, MIBG scan, polysomnography, genetic testing, autonomic function tests, inflammatory tests, skin biopsy) the investigators aim to achieve this through:
-
Longitudinal tracking of clinical progression through use of clinical scales including at the present time: UMSARS, BARS, MoCA and UPSIT, PROM, MDS-NMS, UPDRS, and SARA
-
Longitudinal tracking of disease progression through use of neuroimaging including at the present time: TSPO-PET and 3D MRI (see section 1.3)
This is a pilot study designed to track patients with neurodegenerative movement disorders across Mass General Brigham through MRI and PET imaging modalities and clinical measures. Figure 5 represents the study design in detail. In short, subjects will be asked to visit Mass General Brigham every 6-9 months over the course of 18 months for imaging and clinical evaluation.

Outcome Measures
Primary Outcome Measures
- association between change in PET and clinical measures [18 months]
For the longitudinal evaluation, the investigators will estimate the association between the change in the PET and the change in the clinical and morphometric outcome measures using a mixed model with both the baseline PET uptake and the rate of change in PET uptake as predictors. This approach will allow the investigators to estimate both how between and within subject changes in PET impact the outcomes of interest. The investigators will use a p<0.05, corrected for multiple comparisons.
