Factors independently linked to dementia on regression analysis included advanced age (OR: 1.182, 95% CI: 1.075–1.299; p = 0.001), female sex (OR: 30.895, 95% CI: 5.039–189.422; p = 0.001), presence of diabetes (OR: 5.188, 95% CI: 1.180–22.811; p = 0.03), elevated pulmonary artery systolic pressure at presentation (OR: 1.109, 95% CI: 1.034–1.299; p = 0.0304) and a lower serum albumin (OR: 0.148, 95% CI: 0.026–0.849; p = 0.03). The gene discussed is ALB; the disease is dementia.
