University Hospital, Bordeaux
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.

Condition Intervention
Cluster Headache Other: Neurological clinical examination Other: Psychological clinical examination Other: Questionnaires Other: Blood sample Other: Endothelial function measurement

Study Type: Observational [Patient Registry]
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 12 Months
Official Title: Cluster Headache (CH), Addictions and Vascular Function

Estimated Enrollment: 150
Study Start Date: June 2014
Estimated Study Completion Date: June 2017
Estimated Primary Completion Date: June 2017 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Patient with Cluster headache
Prospective follow-up of patient with Cluster headache
Other: Neurological clinical examination
Diagnostic and description of cluster headache
Other: Psychological clinical examination
Scale and questionnaires
Other: Questionnaires
Psychopathological and cognitive questionnaires
Other: Blood sample
Blood sample for DNA collection
Other: Endothelial function measurement
Endothelial function will be measured with a noninvasive Peripheral Arterial Tone (PAT) signal technology using the EndoPAT device

Detailed Description:

Several studies have shown an association between Cluster headache (CH) and smoking. However, no data exists on the link between CH and other addictions, and impact of these addictions on clinical characteristics of the disease. In addition, despite the strong biological link between CH and the vascular system, systematic investigations about vascular functions in CH patients are lacking.

This will be a prospective cohort study of 150 patients with CH, conducted in the Headache Center in Bordeaux, France.
