Hello
Increased T2 signals in periventricular and subcortical white matter of brain may be due to ischemic changes resulting from involvement of small blood vessels(vasculitis),
demyelination,sequela of remote head trauma etc.
Ischemic changes resulting from blood vessels changes in diseases like
hypertension,
diabetes mellitus,dyslipidemia.
So,you 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.
You need investigations like routine hemogram,RBS,LFT,RFT,Lipid profile,ultrasound of abdomen.
Temporal lobes are normal.
Proper treatment depend upon findings.
You also need follow up scan.
