Temporal arteritis, also known as giant cell arteritis, is an inflammatory condition that affects the blood vessels, particularly those in the head and neck. It primarily occurs in older adults and can lead to serious complications, including vision loss if not treated promptly. Symptoms often include headaches, scalp tenderness, and jaw pain. Diagnosis typically involves blood tests to check for inflammation and imaging studies. Treatment usually consists of high doses of corticosteroids to reduce inflammation and prevent complications. Early detection and management are crucial for preserving vision and overall health.
