Longitudinal Structural Brain Alterations in Parkinson’s Disease Patients with Freezing of Gait (2708)

The main objective of this study is to investigate the cortical and subcortical grey matter (GM) changes in Parkinson’s disease (PD) patients with freezing of gait (FoG) over one and two years of follow-up. We also investigated GM features of PD patients developing FoG (PD-FoG-converters) within two years.
