Temporal arteritis, also known as giant cell arteritis, is a condition where the arteries become inflamed and damaged.
It primarily affects the large and medium-sized arteries in the head, particularly the temporal artery located on the sides of the forehead. This condition can cause serious complications if left untreated, including vision loss and stroke. To understand temporal arteritis, it’s important to know the causes and symptoms.
Causes of Temporal Arteritis
The exact cause of temporal arteritis is unknown, but the immune system may play a role.
It is believed that the condition may be triggered by an autoimmune response, where the body’s immune system mistakenly attacks healthy tissues, including the temporal artery. Genetic and environmental factors may also contribute to the development of temporal arteritis.
Symptoms of Temporal Arteritis
Temporal arteritis can cause a wide range of symptoms that can mimic other conditions. The signs and symptoms may develop gradually or appear suddenly and can include:.
- Headaches, particularly in the temples
- Tenderness and pain in the scalp
- Jaw pain or pain when chewing
- Fever or unexplained weight loss
- Visual disturbances or sudden permanent loss of vision in one eye
- Fatigue or malaise
- Muscle aches and stiffness, especially in the neck, shoulders, and hips
Diagnosing Temporal Arteritis
Diagnosing temporal arteritis can be challenging because the symptoms can be vague and can mimic many other conditions. A physical exam and blood tests can help confirm the diagnosis.
A temporal artery biopsy may also be performed to look for signs of inflammation.
Treatment of Temporal Arteritis
Temporal arteritis is treated with medications to reduce inflammation and prevent damage to the arteries. Corticosteroids such as prednisone are usually prescribed and may need to be taken for several years to prevent a relapse.

Other medications such as methotrexate and tocilizumab may also be used in combination with corticosteroids to help reduce inflammation. Prompt treatment is essential to prevent any complications.
Preventing Temporal Arteritis
There are no proven ways to prevent temporal arteritis, but maintaining a healthy lifestyle may help reduce the risk. Eating a nutritious diet, exercising regularly, and avoiding smoking are all important for overall health and well-being.
Complications of Temporal Arteritis
Temporal arteritis can cause serious complications if left untreated. The inflammation can lead to scarring and narrowing of the arteries, reducing blood flow to the affected organs.
The most serious complication is vision loss, which can be sudden and permanent in some cases. Stroke and aneurysm are also possible complications.
Prognosis of Temporal Arteritis
With prompt treatment, the prognosis for temporal arteritis is generally good. Most people will recover with few or no complications. However, some people may experience a relapse of the condition even after treatment.
Long-term use of corticosteroids can also cause side effects, so regular monitoring by a healthcare provider is important.
Conclusion
Temporal arteritis is a serious condition that can have debilitating complications if left untreated. Knowing the causes and symptoms is essential for prompt diagnosis and treatment.
If you are experiencing any of the symptoms of temporal arteritis, seek medical attention immediately.
