Anodal Transcranial Direct Stimulation (tDCS) for the Treatment of Chronic Cluster Headache (ANODECCH)
Anodal Transcranial Direct Stimulation (tDCS) of the Anterior Cingulate Gyrus for the Treatment of Chronic Cluster Headache: a Pilot Trial.
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.
Study Overview
Detailed Description
Cluster headache affects 0.1%-0.25% of the general population, but its prevalence may be underestimated. It is a primary headache disorder with a higher prevalence in young males, characterized by attacks of severe unilateral periorbital/temporal pain with autonomic symptoms (ie lacrimation, nasal congestion, eyelid edema, Horner's…) and agitation, lasting 15 to 180 minutes and occurring periodically in bouts (clusters) in about 90% of patients (episodic cluster headache or ECH, ICHD-III criteria 3.1.1).In 10% of patients there is no sustained spontaneous remission for long periods, which defines chronic cluster headache (CCH, ICHD-III criteria 3.1.2).
The pathophysiology of cluster headache is not completely understood, but neuroimaging studies clearly suggest that activation of the ipsilateral postero-ventral hypothalamus plays a seminal role during the attack. Recent findings suggest that prefrontal areas may be dysfunctioning in cluster headache patients. The investigator shave shown in CCH patients that the beneficial effects of ONS are associated with activation of the subgenual anterior cingulate cortex, an area responsible for descending pain-control. Transcranial direct current stimulation (tDCS) allows activating the underlying cortex and connected subcortical structures under the anode or inhibiting them under the cathode. tDCS was used as a therapeutic strategy in various neurological disorders, chronic pain disorders and depression. Because of its non-invasiveness, It is of particular interest in primary headaches where various brain areas are known to function abnormally even between headache attacks. It has been tested in migraine but not in cluster headache.
In a recent study, the investigators have shown that anodal tDCS over the visual cortex is able to modify visual evoked potentials in healthy volunteers and migraineurs, and after a 2-month treatment of 2 weekly sessions to significantly decrease attack frequency in episodic migraine.
CCH patients will have to apply the neurostimulation outside of an attack every day for 20 minutes during 4 to 8 weeks.
Adherence to the treatment will be evaluated by monitoring the time during which the device is switched on via an in-built software.

Sponge-electrodes (5 x 7 cm) will be postioned at Fz (anode) and over the spinous process of C7 (cathode). Stimulation intensity will be set to 2 mA. A first group of CCH patients will have to apply the neurostimulation outside of an attack every day for 20 minutes during 4 weeks. A second group will use the tDCS device everyday for 8 weeks. Adherence to the treatment will be evaluated by monitoring the time during which the device is switched on via an in-built software.
