TSPO and Cognitive impairment: Whole-brain TSPO binding potential was similar in patients with and without cognitive impairment (mean BPND −0.046 [95% CI: −0.105; 0.013] vs −0.047 [95% CI: −0.108; 0.014], p = 0.98), and there were no differences in individual ROIs (Figure 1, Supplemental Table 2, Supplemental Figures 2 and 3).
