NCT02081482

Brief Summary

The occipital nerve stimulation (ONS) is used to treat patients with refractory primary chronic headache but its mechanism of action (MoA) remains unknown. Different hypothesis have been suggested in particular a specific action on cerebral generators involved in different types of primary headaches or a non specific action on pain modulatory network. The aim of this study, using the chronic cluster headache as a model, is to determine the changes in cerebral metabolism induced by ONS to precise its MoA in the treatment of primary chronic headache.
