Cerebral Metabolism in Patients With Refractory Chronic Cluster Headache Treated by Occipital Nerve Stimulation
This trial is active, not recruiting.
|Condition||refractory chronic cluster headache|
|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.
