DOCK3 and supranuclear palsy, progressive, 1: Moreover, taking into consideration that the correlation coefficients (rs) of the clinical scores related to cognitive and motor function were quite similar between CBS (MoCA, rs = −0.41; MMSE, rs = −0.41; PSPRS Gait/Midline, rs = 0.41; UPDRS-III, rs = 0.36) and PSP-RS (MoCA, rs = −0.39; MMSE, rs = −0.33; PSPRS Gait/Midline, rs = 0.49; UPDRS-III, rs = 0.41) and because the overlap in CBS and PSP-RS between clinical symptoms including cognitive and motor function is well-known, the SuStaIn stage could reflect exactly the disease severity of cognitive function.
