Furthermore, these measured DAT-SPECT SBRs were found to inversely correlate with the MDS research criteria for prodromal disease likelihood ratio (LR) scores [80,81] in the GBA1-NMC group; whereas rs-fMRI FC levels were associated positively with LR scores in the LRRK2-NMC group. Here, GBA1 is linked to nut midline carcinoma.
