Giant cell arteritis (GCA), also called temporal arteritis, is an inflammatory autoimmune disease of large blood vessels. [ 4 ] [ 7 ] Symptoms may include headache , pain over the temples, flu-like symptoms , double vision , and difficulty opening the mouth. [ 3 ]
Takayasu arteritis (TA) is a large-vessel, idiopathic, granulomatous arteritis that primarily affects the aorta, significant branches of it, and (less frequently) the pulmonary arteries. [6] The disease's symptoms can range from catastrophic neurological impairment to an asymptomatic condition brought on by impalpable pulses or bruits . [ 7 ]
Temporal arteritis is an inflammatory disease of medium-sized blood vessels that happens especially with advancing age. AAION occurs in about 15-20 percent of patients with temporal arteritis. Damage to the blood vessels supplying the optic nerves leads to insufficient blood supply ( ischemia ) to the nerve and subsequent optic nerve fiber death.
The most definitive diagnostic modality is a biopsy of the affected blood vessel however brain biopsy has a low yield, with up to 30-50% of biopsies being normal in suspected cases. [5] This is due to some cases having an irregular distribution of vessel involvement (making biopsy technically difficult) or larger vessels being unable to be ...
This form of ischemic optic neuropathy is generally categorized as two types: arteritic AION (or AAION), in which the loss of vision is the result of an inflammatory disease of arteries in the head called temporal arteritis, and non-arteritic AION (abbreviated as NAION, NAAION, [1] or sometimes simply as AION), which is due to non-inflammatory ...
Temporal arteritis, the second type of giant cell arteritis, is also a chronic, inflammatory disease involving mid- to large-sized arteries. [8] Temporal arteritis has a higher incidence in people of Scandinavian descent. [8] However, the incidence rate differs based on population, region and races. [8]
BvFTD, which results from damage to the frontal lobes of the brain, mainly causes problems with behaviour and personality. PPA, when damage occurs to the temporal lobes on either side of the head ...
About 15% of people who are diagnosed with polymyalgia rheumatica also have temporal arteritis, and about 50% of people with temporal arteritis have polymyalgia rheumatica. Some symptoms of temporal arteritis include headaches , scalp tenderness, jaw or facial soreness, distorted vision , or aching in the limbs caused by decreased blood flow ...
