title: [Headache: physical exam or CT?].
abstract: The life time prevalence of headache is more than 90% in the general population. The majority of patients presenting to physicians suffer from migraine. A simple clinical predictive score based on five questions will allow clinicians to confirm this diagnosis and will prevent further investigations. In all other circumstances, evidence is not sufficient to develop prediction rules to exclude secondary headache. However, neuroimaging should be performed in patients with a unexplained abnormal finding on the neurological examination.
