Hello
Thanks for writing to HCM
FLAIR or T2 weighted hyper intensities less than five in number in deep white matter of brain can be ignored.
Mostly it is due to ischemic changes(decreased blood supply) that involves small blood vessels.However
demyelination,lyme disease should also be ruled out with follow up scans.
Hyper intensities more than five in number should be the cause of concern and it need investigations.
You need monitoring of conditions that leads to ischemic changes like
hypertension,altered
lipid profile,
diabetes mellitus.
You need investigations like routine hemogram,RBS,LFT,RFT,Lipid profile,ultrasound of abdomen.
If there is any more physical problems then it should be treated.
Carotid artery changes are also due to hypertension.
Get well soon.
Hope i have answered your query.
Take Care
