Cause of Temporal Arteritis
While no one knows for certain why the condition occurs, it is believed that temporal arteritis may be caused by abnormalities in the immune system and certain genetic factors. There are also some risk factors for the disease, including being over 50 years old and having a history of polymyalgia rheumatica.
Temporal arteritis is a condition that results in the swelling of arteries in the head, neck, and arms. The temporal arteries (which are located on the temples on each side of the head) are most often affected. No one knows the exact cause of this disorder. However, research scientists believe the causes of the condition may have something to do with the immune system and genetic factors.
Research has shown that people with certain risk factors are more likely than others to develop the disorder. A risk factor is anything that increases a person's chance of developing a disease.
Specific risk factors for temporal arteritis include:
- Age over 50
- History of polymyalgia rheumatica (PMR).
People with known risk factors and those who are concerned about temporal arteritis should ask their doctor about the symptoms to watch for and how often to have checkups. Untreated, temporal arteritis can lead to serious complications, including permanent vision loss and stroke.
