Thank you for posting your query.
The CT brain findings are not something to be concerned about. Atrophy
(shrinkage of brain) is normal with advancing age, and is a natural process, which can not be reversed.
Regarding ischemic changes (lack of blood supply to brain), you should get your risk factors screened for (including BP, sugar, cholesterol
, etc). After consulting a doctor, you may need to take aspirin
to prevent further brain ischemia
Please get back if you require any additional information.
