Hello
Thanks for writing to HCM
Ischemia or early infarction in the left external capsule and bilateral periventricular
white matter low attenuation is due to chronic microvascular ischemic changes resulting from involvement of small blood vessels.
Ischemic changes resulting from blood vessels changes in diseases like
hypertension,
diabetes mellitus,dyslipidemia.
So,your grand mother need monitoring of conditions that leads to ischemic changes like hypertension,altered
lipid profile,diabetes mellitus so that further progression of disease can be halted.
She need investigations like routine hemogram,RBS,LFT,RFT,Lipid profile,ultrasound of abdomen.
Proper treatment depend upon findings.
Hope i have answered your query.
Take Care
