P023. Reasons for headache investigation and findings in an experimental headache center

Background Warning symptoms or “red flags” are useful in targeting which patients with headache require investigation. Many red flags, even with normal neurological examination, are the cause of neuroimaging (CT or MRI) overutilization, in addition to patient reassurance. Optimizing headache neuroimaging practices should be a major priority. The aim of our study was to evaluate the investigation rate in patients referred for the first time in the period from 2011 to 2013 to our Headache Center (HC) conducted by a general practitioner particularly an expert in headache management, and to correlate the reasons of investigation with neuroradiological findings.
