APOE and dementia: Similar to other dementia subtypes, TBI (OR with 95% CI for midlife 6.82 [1.69–27.48] and for late-life OR 6.98 [3.25–14.97]) and APOE e4/e4 genotypes (OR with 95% CI for midlife 3.08 [1.93–4.90] and for late-life OR 4.23 [3.31–5.40]) were among the top risk factors with high odds ratios.
