what causes blood vessel damage
In addition, blood vessel damage in 59 people with mild memory problems who were included in the study were signs that they were at risk for Alzheimer's disease, the researchers added. Brickman noted that these areas of blood vessel damage are seen in most patients with Alzheimer's disease.
Like other vessels, they, too, can be damaged by high blood pressure: Eye blood vessel damage (retinopathy). High blood pressure can damage the vessels supplying blood to your retina, causing retinopathy. This condition can lead to bleeding in the eye, blurred vision and complete loss of vision. If you also have both diabetes and high blood pressure, you're at an even greater risk.
Vasculitis (vas-kyu-LI-tis) is a condition that involves inflammation in the blood vessels. The condition occurs if your immune system attacks your blood vessels by mistake. This may happen as the result of an infection, a medicine, or another disease or condition. âInflammationâ refers to the bodyâs response to injury, including injury to the blood vessels.
In some cases, the retina becomes swollen. Over time, high blood pressure can cause damage to the retinaâs blood vessels, limit the retinaâs function, and put pressure on the optic nerve, causing vision problems. This condition is called hypertensive retinopathy (HR). Advertisement.
