A question for your doctor to answer, I wouldn't presume to get between you and your doctor or therapists. They are the ones with the years of medical education.

BACKGROUND Despite several known risk factors it is still difficult to
foresee who will develop a stroke and who will not. Vascular brain
damage, visualised with MRI, reflects how the brain tolerates the
effects of vascular risk factors and may therefore be relevant in
predicting individual stroke risk. OBJECTIVETo examine whether the
presence of small vessel disease on brain MRI could improve the
prediction of stroke beyond the classic stroke risk factors from the
1991 Framingham Stroke Risk Function. METHODS1007 community-dwelling
elderly people, free of stroke at baseline were included in the study.
Small vessel disease--that is, the presence of silent brain infarcts
(SBI) and white matter lesions (WML), was scored on MRI scans obtained
in 1995-6. 10-Year stroke risk prediction was assessed by the C
statistic and by reclassification adding SBI and WML to a risk model
including the classic stroke risk factors. RESULTSDuring 10-years of
follow-up 99 strokes occurred. Individual stroke risk prediction
significantly improved from 0.73 (95% CI 0.67 to 0.78) to 0.75 (0.69 to
0.80) in men and from 0.69 (0.64 to 0.75) to 0.77 (0.71 to 0.82) in
women after inclusion of SBI and periventricular WML to the stroke risk
factors. Reclassification occurred mainly in the intermediate stroke
risk group (men 26%; women 61% reclassified).
CONCLUSIONS
Assessment of
small vessel disease with MRI beyond the classic stroke risk factors
improved the prediction of subsequent stroke, especially in women with
an intermediate stroke risk. These findings support the use of MRI as a
possible tool for better identifying people at high risk of stroke.
