Pietro Mazzoni, MD, PhD

Assistant Professor of Neurology
Co-Director, Motor Performance Laboratory 

Dr. Mazzoni studies the motor manifestations of Huntington's disease using quantitative analysis of reaching and pointing hand movements in the Motor Performance Laboratory and in the Functional MRI Center. The goal of his research is to understand how the brain degeneration caused by HD leads to impairments of movement and motor learning. This research may lead to various future applications, including: 1) establishing the earliest manifestations of HD, so that the effects of potentially neuroprotective treatments may be measured before the disease has caused significant impairment; 2) guiding the choice of structures to be targeted by possible neurosurgical treatments, analogous to deep brain stimulation for Parkinson's disease; 3) developing rehabilitation techniques specifically helpful to people with HD. Dr. Mazzoni's lab website can be visited at Motor Performance Laboratory.
