    Sex-Related Differences of Resting-State Brain Activity in Parkinson’s Disease

    R. Li, W. Li, Y. Liu (Beijing, China)

    Objective: To investigate sex-related differences of resting-state functional magnetic resonance imaging (rs-fMRI) metrics in early-stage, untreated Parkinson’s disease (PD) patients. Background: Sex plays an important role in the heterogeneity of PD, but its effects…
