Cholinergic System Changes in Dopa‐Unresponsive Freezing of Gait in Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Freezing of gait (FoG) is a debilitating mobility disturbance that becomes increasingly resistant to dopaminergic pharmacotherapies with advancing Parkinson's disease (PD). The pathophysiology underlying the response of FoG to dopaminergic treatment is poorly understood.

Positron Emission Tomography Imaging in Clinical Trials for Parkinson's Disease: Applications of Metabolic Brain Network Approach

open access: yesMovement Disorders, EarlyView.
ABSTRACT Neuroimaging with positron emission tomography (PET) has been instrumental in elucidating neurobiological mechanisms behind therapeutical trials in Parkinson's disease (PD). A variety of medical and neurosurgical interventions have been evaluated using many radioligands that reveal molecular basis for target engagement and brain responses in ...
