The minor allele of the dopamine receptor D1 (DRD1, rs4532) polymorphism showed potential association (p = 0.022) with an increased risk of NPM at 12 weeks post-stroke in the elderly, both in the additive (OR, 2.94; 95% CI, 1.17–7.37) and dominant models (OR, 2.93; 95% CI, 1.04–8.23) but did not reach statistical significance after Bonferonni correction. Here, DRD1 is linked to Stroke.
