Temporal Arteritis - Causes

What causes temporal arteritis?

Temporal arteritis is believed to be an autoimmune disorder in which the immune system mistakenly attacks normal cells of the large and medium arteries in the head. In temporal arteritis, inflammation caused by this attack affects the flow of blood through the arteries and the ability to adequately supply oxygen and nutrients to the brain and head areas. Temporal arteritis can also affect other arteries throughout the body.

The cause of temporal arteritis is not known. However, the aging process probably plays a role in developing temporal arteritis, as most people with the disorder are older than age 50.

What are the risk factors for temporal arteritis?

A number of factors increase the risk of developing temporal arteritis. Not all people who are at risk for temporal arteritis will develop the condition. Risk factors include:

Advanced age
Family history of temporal arteritis
Female gender
Polymyalgia rheumatica (inflammatory disorder causing pain and stiffness in the neck, shoulder and hip areas)
