Headache to worry about

The headache to worry about is one that is unique or different from headaches which the patient has suffered in the past. The association with the headache of meningismus or of focal neurologic symptoms of oculoparesis, other cranial nerve palsies, hemiparesis, or loss of consciousness are particularly worrisome, especially if onset is recent and acute. Headaches related to arteritis or vasculitis usually have a slower subacute course but may also produce focal neurologic deficits. For subjects over 50 years old, temporal arteritis is always a consideration and any new type of headache requires testing of the sedimentation rate to rule out this treatable but potentially devastating problem.
