Anodal Transcranial Direct Stimulation (tDCS) for the Treatment of Chronic Cluster Headache

Cluster headache is a primary headache that chiefly affects young men, and is less common than migraine. This disease can have devastating consequences due to the pain intensity (it is also called \"suicide headache\"), to the side effects of the drug preventive therapies, and to the resistance of some subtypes of the headache to all existing medications. Recent studies suggest that cluster headache could be associated with a decrease of the activity of frontal areas involved in descending pain control, in particular the subgenual anterior cingulate cortex. The aim of this pilot study is to activate these areas with a non-invasive neurostimulation technique, called transcranial direct current stimulation, as a preventive treatment for cluster headache sufferers.
