The major complication of dopaminergic therapy in Parkinson’s disease (PD) is dyskinesia which affects patients' quality of life. The pathogenesis of levodopa-induced dyskinesia (LID) remains unclear. In this study, we aimed to investigate striatum-thalamus alterations in PD patients with and without LID using advanced diffusion magnetic resonance imaging (dMRI) techniques (DTI, DKI, NODDI and MAP).
