The effects of peripheral occipital nerve stimulation for the treatment of patients suffering from chronic migraine: a single center experience.

About 1% of patients suffering from chronic migraine do not respond to medications and require more invasive treatments. Occipital nerve stimulation (ONS) is one of these new therapeutic options. The aim of this data review is to evaluate the clinical impact of ONS and whether the neuropsychological aspects of anxiety and depression can be considered as predictors of therapeutic effects.
