Symptoms of GCA typically include headaches, pain in the jaw or tongue muscles when eating or talking and tenderness of the scalp over the temples.
Causes and Risk Factors
The cause of this disorder is not known. Because it almost always occurs in people over the age of 50 (the average age of persons with GCA is about 70), it may be related to the aging process. Genetic factors may also be involved. GCA occurs twice as often in women as in men.
