[|Human|] Hi- I am trying to gather as much information to send to my Foster sister on Atherosclerosis of brain arteries. Her Father has some plaque build up of one or more arteries of the brain, but I do not know which are affected. I explained some to her this afternoon, but I am trying to get more explicit information to give to her, to prevent a stroke in her father. She has durable power of attorney for him. They just did a CATT scan, as he gave them a bad scare on Friday night, but he has pneumonia. The CATT Scan did show he has atherosclerosis of at least one brain artery. He fell off a ladder helping a neighbor a few weeks ago and broke his pelvis and some lumbar vertebrates.
[|AI|]  Hi, thanks for using Chat Doctor Stroke prevention involves controlling risk factors such as high blood pressure, diabetes, high cholesterol, smoking. By controlling these factors the risk of a stroke is reduced. This means that all of the above should be maintained within normal range. Different blood vessels are involved in supplying different aspects of the brain and signs and symptoms of stroke would vary somewhat according to the area affected. I hope this helps
