It mainly involves the extracranial branches of the carotid artery in patients over 50 years of age.

Any elderly person over 50 years of age with unexplained fever, lethargy, wasting, anemia, hematoma >50 mm/h; newly occurred headache, visual disturbance (blackout, blurred vision, diplopia, blindness); or other signs of insufficient cranial artery supply, such as intermittent arterial disturbance of the masticatory muscles, tinnitus, vertigo, etc.; or PMR syndrome, etc. should suspect this disease and urgently undergo further investigations, such as temporal arteriography, temporal artery biopsy, and other tests. The disease should be suspected and further investigations, such as temporal arteriography and temporal artery biopsy, should be performed as soon as possible to confirm the diagnosis. If conditions do not allow, glucocorticoid therapy can be tried after excluding other rheumatic diseases and other conditions.
