You very likely want this testing. As a result of your stroke you have these chances of getting dementia.
Your chances of getting dementia.
2. Then this study came out and seems to have a range from 17-66%. December 2013.
Then your doctor can prescribe the protocols to prevent such dementia. Your doctor will have none, having done nothing in the last 7 years. Do you prefer your doctor being incompetent in not knowing or not doing? I assume I have this since my doctor told me I had lots of white matter hyperintensities from small strokes. Of course he showed my no scan. And I'm now 13 years out and I believe I'm showing no signs of dementia.

Using diffusion tensor imaging segmentation, an advanced MRI brain
scan analysis, researchers were able to assess microstructural brain
damage to predict dementia in patients with cerebral small vessel
disease and lacunar strokes.
According to the study published in
Stroke, the diffusion
tensor imaging segmentation (DSEG) technique, acting as a marker of
cerebral small vessel disease (SVD) severity, is sensitive enough to
distinguish from a single imaging modality
whether an individual will develop dementia within a 5-year period, according to the study.
“Following a group of
patients with SVD
over 5 years, we predicted who would develop difficulties with
executive functions (planning, organizing information and flexible
thinking) or go on to develop vascular dementia,”
Rebecca A. Charlton, PhD,
of the department of psychology at Goldsmiths, University of London,
told Healio. “We know that vascular disease can impact the brain, and
through accumulated damage affect cognitive function. This research
shows that existing damage in the brain and additional damage over time
lead to specific problems in executive functions; memory abilities were
spared.”
The researchers found that dementia risk increased according to
baseline DSEG- (HR = 3.331; 95% CI, 2.076-5.343) and change in DSEG- (HR
= 3.905;
P < .001).
Furthermore, DSEG in patients with SVD and lacunar strokes was significantly related to cognitive decline (
P < .001), with a balanced classification rate of 75.95% (area under the curve, 0.839).
“A key concern for patients is the long-term trajectory
of their illness. This is particularly true when cognitive abilities are
at risk of decline,” Charlton said. “While this research is not yet
ready for use in clinical practice, it shows promise that it may be
possible to predict individual trajectories. Such individualized
healthcare will allow for early, targeted treatment to slow disease
progression.”
Researchers analyzed 99 patients with SVD (mean age, 68 years; 66%
men) who underwent annual DSEG for 3 years and cognitive assessment for 5
years, using DSEG- as a measure of SVD severity. Additionally, a Cox
regression identified which DSEG measures and vascular risk factors were
associated with an increased risk for dementia, according to the study.
“Importantly, this new technique, DSEG, relies on just
one readily available MRI scan. Previous research predicting cognitive
decline and dementia generally use several scans and/or several
different clinical tests. By using just one scan, the patient can spend
less time in the MRI scanner, and the results are equally accurate.” – by Scott Buzby
