Taken together with our previous study of DLB and PD [8], in terms of the correlation between the NRCSN-SBR, the present study demonstrated that the five, neurodegenerative diseases causing parkinsonism can be divided into two, distinct groups (significant in PD and CBS and non-significant in DLB, PSP, and MSA-P). Here, CBS is linked to neurodegenerative disease.
