BACKGROUND AND PURPOSE: The main aims of this study were to evaluate: the diffusion, use and perception of the usefulness of the 2004 EFNS guidelines on neurophysiological testing in non-acute headache patients; the frequency with which the different neurophysiological tests were recommended in non-acute migraine patients by physicians aware or unaware of the guidelines; and the appropriateness of the reasons given for recommending neurophysiological tests. METHODS: One hundred and fifty physicians selected amongst the members of the Italian societies of general practitioner (GPs), neurologists and headache specialists were contacted via e-mail and invited to fill in a questionnaire specially created for the study. RESULTS: Ninety-two percent of the headache specialists, 8.6% of the neurologists and 0% of the GPs were already aware of the EFNS guidelines. A significantly higher proportion of headache specialists had not recommended any neurophysiological tests to the migraine patients they had seen in the previous 3 months, whereas these tests had frequently been prescribed by the GPs and neurologists. Overall, 80%, 42% and 42.6% of the reasons given by headache specialists, neurologists and GPs, respectively, for recommending neurophysiological testing in their migraine patients were appropriate (P < 0.01). CONCLUSIONS: The diffusion of the EFNS guidelines on neurophysiological tests and neuroimaging procedures was found to be very limited amongst neurologists and GPs. The physicians aware of the EFNS guidelines recommended neurophysiological tests to migraine patients less frequently and more appropriately than physicians who were not aware of them. The most frequent misconceptions regarding neurophysiological tests concerned their perceived capacity to discriminate between migraine and secondary headaches or between migraine and other primary headaches.

Animal models of human disease have been extremely helpful both in advancing the understanding of brain disorders and in developing new therapeutic approaches. Models for studying headache mechanisms, particularly those directed at migraine, have been developed and exploited efficiently in the last decade, leading to better understanding of the potential mechanisms of the disorder and of the action for antimigraine treatments. Model systems employed have focused on the pain-producing cranial structures, the large vessels and dura mater, in order to provide reproducible physiological measures that could be subject to pharmacological exploration. A wide range of methods using both in vivo and in vitro approaches are now employed; these range from manipulation of the mouse genome in order to produce animals with human disease-producing mutations, through sensitive immunohistochemical methods to vascular, neurovascular and electrophysiological studies. No one model system in experimental animals can explain all the features of migraine; however, the systems available have begun to offer ways to dissect migraine's component parts to allow a better understanding of the problem and the development of new treatment strategies.
