title: Diagnostic testing for headache.
abstract: A careful and complete headache history supplemented by a neurologic and general physical examination, as appropriate, enables the astute physician to diagnose most headaches correctly without diagnostic testing. When indications are present (see Box 1), some headache patients with a normal physical examination require testing even though the yield may be low. Failure to test may result in misdiagnosis of potentially serious and life-threatening causes of headaches, such as brain tumors, chronic meningitis, SAH, and temporal arteritis.
