Giant Cell Arteritis
Giant Cell Arteritis (GCA) is an autoimmune disease that affects the medium and large arteries in the head and neck regions. It is characterized by inflamed blood vessels, leading to a narrowing of the artery, which can result in reduced blood flow and decreased oxygen levels in the affected areas. GCA can cause a range of symptoms, such as headaches, vision changes, jaw pain, and muscle aches. If left untreated, GCA can lead to permanent physical damage and even blindness. Treatment usually involves corticosteroids, biologic medications, and other immunosuppressive medications. Early diagnosis is important to manage the disease and prevent complications.
