The diagnosis of PD remains still clinical; nevertheless, in the last decades, the rapid evolution of advanced MRI techniques have made it possible to detect structural and, increasingly, functional brain changes in patients with PD. Indeed, functional MRI (fMRI) techniques have offered the opportunity to directly measure the brain’s activity and connectivity in patients with PD both in early and complicated stage of the disease. The aims of the following review are: 1) to present an overview of recent fMRI reports investigating the activity and connectivity of sensorimotor areas in patients with PD using both task-related and resting state fMRI analysis 2) to elucidate potential pathophysiological mechanisms underlying dyskinetic motor complications in the advanced stage of PD
