Official Title: Cluster Headache (CH), Addictions and Vascular Function
Brief Summary: Cluster headache (CH) is one of the most painful primitive headaches. Developments in neuroimaging have demonstrated activation of the ipsilateral hypothalamic and orexinergic system, which is similar in patients with addictions. CH has strong links to the vascular system but there is no study measuring endothelial function in CH sufferers.
