question: i was having headaches and had an MRI of the brain. The neurologist looked at the disk and said I have small vessel changes and premature hardening of the arteries ( I am just 51). My blood pressure is good and I do not smoke. I exercise, eat fairly healthy. I was surprised to learn I have this. He told me to take a low dose aspirin daily. Should I be concerned since I m healthy and just 51 ?
