I am concerned that there is a large amount of misinformation online about Giant Cell Arteritis and even doctors are confused about exactly what this illness entails.
Giant Cell Arteritis causes inflammation of large and medium sized arteries of the body. If the temporal arteries are affected, this is specifically called 'temporal arteritis'. Inflammation of the temporal arteries can cause total blindness but if prednisone is administered, the loss of sight can be recoverable in some instances. If anti-inflammatory medication does not reduce the inflammation sufficiently, the arteries can be damaged, and the stroke, heart attack and dementia risk can be increased. There are some videos on youtube under the Vasculitis Foundation channel which have been produced by professionals and give some sound advice.
