<unk>  <unk> , also called temporal<unk> , is an inflammatory autoimmune disease of large blood vessels. Symptoms may include headache, pain over the temples, flu-like symptoms, double vision, and difficulty opening the mouth. Complication can include blockage of the artery to the eye with resulting blindness, aortic dissection, and aortic aneurysm.<unk>  is frequently associated with polymyalgia rheumatica. The cause is unknown. The underlying mechanism involves inflammation of the small blood vessels that supply the walls of larger arteries. This mainly affects arteries around the head and neck, though some in the chest may also be affected. Diagnosis is suspected based on symptoms, blood tests, and medical imaging, and confirmed by biopsy of the temporal artery. However, in about 10% of people the temporal artery is normal. Treatment is typical with high doses of steroids such as prednisone or prednisolone. Once symptoms have resolved, the dose is decreased by about 15% per month. Once a low dose is reached, the taper is slowed further over the subsequent year. Other medications that may be recommended include bisphosphonates to prevent bone loss and a proton-pump inhibitor to prevent stomach problems. It affects about 1 in 15,000 people over the age of 50 per year. The condition mostly occurs in those over the age of 50, being most common among those in their 70s. Females are more often affected than males. Those of northern European descent are more commonly affected. Life expectancy is typically normal. The first description of the condition occurred in 1890.
