Thanks for posting this question in HCM
I have noted the findings of various investigations.
Please note that all these interpretation of the scans results are done in the context of a solid clinical data. I wish you had mentioned about the exact neurological problem your father had like stroke
, visual problem etc. Apart from this you should also have mentioned if he is a diabetic or he has hypertension
related issues or not and o on.
The investigations suggest that probably had strokes in various areas of brain. The Doppler shows cholesterol deposits.
He needs blood thinners like Aspirin
to prevent it from happening again. His blood pressure and cholesterol should be checked and he will have to be on medicines for the same.
Hope this helps
