†In a pooled cohort of Parkinson’s Disease patients at baseline, higher hs-cTnI was associated with a lower score on the MoCA (beta -0.173, 95% CI -0.300; -0.079). This association was not significant after full adjustments (per ng/L increase in troponin, beta -0.047 lower score on MoCA, 95% CI -0.160; 0.066). This evidence concerns the gene TNNI3 and Parkinson disease.
