We found a significant correlation between low SUVr values in the thalamus at baseline and MOCA worsening from “2-yrs” to “6-yrs” follow-up visits in the early-iPD group (r = 0.996; P = 0.034).

GBA-PD patients showed a significantly lower DAT SUVr in the bilateral ventral striatum than HC and iPD.

Fig 3. Baseline: GBA-PD patients showed a significantly lower DAT SUVr in the bilateral ventral striatum than HC and early-iPD and late-iPD. The GBA-PD group showed a significantly lower 123I-FP-CIT SUVr in the whole contralateral putamen, anterior and motor putamen, globus pallidus, hippocampus, and amygdala than the early-iPD group.

[longi] From baseline to “2-years” follow-up, we found that the GBA-PD showed a global SUVr rate of change (i.e., mean rate of change of all considered ROIs) equal to 0.11, early-iPD equal to 0.09, and late-iPD equal to 0.16 (Fig. 4). The late-iPD group showed the highest global SUVr rate of change. Of note, we found that the early-iPD and late-iPD groups significantly increased their SUVr rate of change, namely significant SUVr reductions over time, in the ventral striatum in comparison with the GBA-PD group at “2-years” (early-iPD vs. GBA-PD P = 0.024; late-iPD vs. GBA-PD P < 0.001). 더 빠른 진행 X

The linear regression model revealed that low SUVr values in the caudate nucleus (motor division) at baseline were associated with UPDRS-III motor scores worsening from “2-years” to “6-years” follow-up visits in the whole PD patients (B = 6.46; P = 0.021) and in the late-iPD group (B = 10.26; P = 0.009). In the whole PD group (385 patients).

Longi: GBA-PD = “cortical thinning of posterior regions, frontal and orbitofrontal cortices; similar pattern of subcortical, hippocampal, and amygdala volume loss (vs. iPD), whereas the pattern of subcortical GM volume (caudate, pallidum, putamen, thalamus, hippo, amygdala) atrophy ( was similar in the two PD group
