[|Human|] CT head without contrast showed atrophy and changes of chronic ischemic white matter disease. I have noticed swelling in several places on my head which is slightly painful to touch and when I lay with the back of my head on a hard surface. I am 70 years old, have PKD, controlled blood presure. What is there to be concerned about? Linda Bench
[|AI|]  Hi, 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. Best wishes, Chat Doctor. Ly/
