Diffusion Tensor Imaging Reflects Degree of Motor Symptoms

In a recent publication in Movement Disorders, Zhang, et al. used PPMI data and found that diffusion tensor imaging (DTI) detected neural fiber abnormalities in people with Parkinson's disease (PD) and that the degree of deviation from normal neural fiber integrity is associated with the severity of motor symptoms in patients.

SWEDDs and Nonmotor Symptoms Publication

In a recent paper in Movement Disorders, researchers sought to better understand SWEDDs compared to people with Parkinson's and healthy controls (HCs) by comparing the nonmotor symptoms for each group using the PPMI baseline data. Certain symptoms, like orthostatic hypotension, were found to be more common in SWEDDs than in PD participants.
