Predictors of Intracranial Pathologic Findings in Patients Who Seek Emergency Care Because of Headache

Abstract

Abnormal results from neurologic examination are the best clinical parameters to predict structural intracranial pathology; however, in patients 55 years or older with headache of acute onset located in the occipitonuchal region that has associated symptoms, computed tomographic scan of the head is justified as part of their clinical evaluation independently of the findings of the neurologic examination.
