Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

AIM: To assess synaptic density and to investigate the potential relationship of regional synaptic loss with motor and non-motor symptoms and with disease progression in the human brain in vivo in patients with PD.

DESIGN: We will include 30 PD patients and 20 healthy controls. All subjects will undergo a clinical examination, with comprehensive assessment of motor and non-motor symptoms, and imaging evaluation consisting of 11C-UCB-J PET-CT and 18F-FE-PE2I PET-MR at baseline and after 2 years.
