I had a CT Brain and the findings were: The cerebral hemispheres and cerebellum show some diffuse involutional changes consistent with the patient's age and are due to small vessel disease. There is no focal or acute pathology with no area of increased or decreased density to suggest significant pathology and no mass effect with shift in midline structures. The ventricular system is normal and there is normal intracranial calcification. I am 75 years old, but strong dementia in my family. Is my brain deteriorating badly?
