    Resting State fMRI: A Valuable Tool for Studying Cognitive Dysfunction in PD by Kai Li, Wen Su, Shu-Hua Li, Ying Jin, Hai-Bo Chen

    Published 2018-01-01
    “…In this review, we summarize rs-fMRI studies on cognitive function in PD and discuss the strong potential of rs-fMRI in this area. rs-fMRI can help reveal the pathophysiology of cognitive symptoms in PD, facilitate early identification of PD patients with cognitive impairment, distinguish PD dementia from dementia with Lewy bodies, and monitor and guide treatment for cognitive impairment in PD. …”
