Condition refractory chronic cluster headache
Treatment 18f-fdg pet
Sponsor Centre Hospitalier Universitaire de Nice
Start date March 2014
End date July 2015
Trial size 20 participants
Trial identifier NCT02081482, 13-AOI-05


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.
