Genetically speaking race does not exist so this line of research doesn't really make sense
. And if we had a
great stroke association sponsoring research we wouldn't be wasting time and money on irrelevant questions.

Abstract
BACKGROUND AND PURPOSE:
It
is unknown whether blacks' elevated risk of dementia is because of
racial differences in acute stroke, the impact of stroke on cognitive
health, or other factors. We investigated whether racial differences in
cognitive decline are explained by differences in the frequency or
impact of incident stroke between blacks and whites, controlling for
baseline cognition.
METHODS:
Among
4908 black and white participants aged ≥65 years free of stroke and
cognitive impairment in the nationally representative Health and
Retirement Study with linked Medicare data (1998-2010), we examined
longitudinal changes in global cognition (modified version of the
Telephone Interview for Cognitive Status) by race, before and after
adjusting for time-dependent incident stroke followed by a
race-by-incident stroke interaction term, using linear mixed-effects
models that included fixed effects of participant demographics, clinical
factors, and cognition, and random effects for intercept and slope for
time.
RESULTS:
We
identified 34 of 453 (7.5%) blacks and 300 of 4455 (6.7%) whites with
incident stroke over a mean (SD) of 4.1 (1.9) years of follow-up
(P=0.53). Blacks had greater cognitive decline than whites (adjusted
difference in modified version of the Telephone Interview for Cognitive
Status score, 1.47 points; 95% confidence interval, 1.21 to 1.73
points). With further adjustment for cumulative incidence of stroke, the
black-white difference in cognitive decline persisted. Incident stroke
was associated with a decrease in global cognition (1.21 points;
P<0.001) corresponding to ≈7.9 years of cognitive aging. The effect
of incident stroke on cognition did not statistically differ by race
(P=0.52).
CONCLUSIONS:
In
this population-based cohort of older adults,
incident stroke did not
explain black-white differences in cognitive decline or impact cognition
differently by race.
This is a BS question that contributes nothing to treatment. Can you spell d-I-f-f-e-r-e-n-c-e-s in e-d-u-c-a-t-I-o-n-a-l o-p-p-o-r-t-u-n-I-t-I-e-s which predicts cognitive decline?
ReplyDeleteYeah, I know these researchers just jumped at the first difference and never stopped to think.
