So since my Mom at 95 still living at home and doing good, dad died at 91 with Parkinsons dementia, at least Parkinsons is not genetic, Maybe my dementia chances are not that great.
But after your stroke how much is your doctor working on preventing dementia in you? They've done nothing for your recovery, are they at least working on preventing your dementia?

Abstract
Background: offspring of long-lived individuals have lower risk for dementia. We examined the relation between parental longevity and
cognition and subclinical markers of brain ageing in community-dwelling adult offspring.
Methods: offspring
participants with both parents in the Framingham Heart Study, aged ≥55
years and dementia-free underwent baseline
and repeat neuropsychological (NP) testing and
brain magnetic resonance imaging (MRI). Parental longevity was defined
as having
at least one parent survive to age ≥85 years. To
test the association between parental longevity and measures of
cognition
and brain volumes, we used multivariable linear and
logistic regression adjusting for age, sex, education and time to NP
testing
or brain MRI.
Results: of 728 offspring (mean age 66 years, 54% women), 407 (56%) had ≥1 parent achieve longevity. In cross-sectional analysis,
parental longevity was associated with better scores on attention (beta 0.21 ± 0.08, P = 0.006) and a lower odds of extensive white matter hyperintensity on brain MRI (odds ratio 0.59, 95% CI: 0.38, 0.92, P
= 0.019). The association with white matter hyperintensity was no
longer significant in models adjusted for cardiovascular
risk factors and disease. In longitudinal analysis
(6.7 ± 1.7 years later), offspring with parental longevity had slower
decline
in attention (0.18 ± 0.08, P = 0.038), executive function (beta 0.19 ± 0.09, P = 0.031) and visual memory (beta −0.18 ± 0.08, P = 0.023), and less increase in temporal horn volume (beta −0.25 ± 0.09, P = 0.005). The associations persisted in fully adjusted models.
Conclusion: parental longevity is associated with better brain ageing in middle-aged offspring.
