Cluster headache (CH) is a rare, excruciating primary headache disorder. A genetic basis has been suggested by family and twin studies, but the mode of transmission seems to vary and the amount of heritability is unclear. The number of genetic association studies investigating variants implicated in the pathophysiology of CH is limited. The HCRTR2 1246G > A and the ADH4 925A > G polymorphisms have been associated with CH. The former has been confirmed and may affect the hypothalamic hypocretin system. The aim of the present study was to investigate the possible link between SPINK 1 gene and cluster headache.
We hypothesized that LF stimulation of the SPG would increase parasympathetic outflow, activate sensory afferents and provoke a cluster-like attack.
It has previously been shown that nitroglycerine induces cluster headache attacks in episodic cluster headache patients (ECH patients) in bouts but not in remission phase. Furthermore, plasma concentrations of calcitonin gene-related peptide (CGRP) have been shown to be significantly higher during, but not before and after, an attack. The attack appears around 20-40 min after nitroglycerine infusion with vasodilatation. During this latency period preceding the attack, no increase in CGRP plasma concentrations is seen. CGRP induces migraine attacks in 65% of migraine patients, and CGRP antagonists as well as monoclonal antibodies against CGRP are effective in migraine treatment. Based on the above the investigators hypothesize the following: 1. Provoking ECH patients in bout with CGRP triggers cluster headache attacks 2. Provoking ECH patients in remission with CGRP does not trigger cluster headache attacks 3. Provoking chronic cluster headache patients with CGRP triggers cluster headache attacks more often than in ECH patients.
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.
This study evaluates the effectiveness of physiotherapy program in the treatment of cluster headaches. Half of participants will receive a program of physiotherapy and usual drugs, while the other will receive an exercise program and usual drugs.
Monitor the safety and performance of the Pulsante Microstimulator System.
The main purpose of this study is to evaluate the efficacy of the study drug known as galcanezumab in participants with chronic cluster headache.
The main purpose of this study is to evaluate the efficacy and safety of the study drug known as Galcanezumab in participants with episodic cluster headaches.
This is an open label, investigator-sponsored, pilot study. Subjects agreeing to participate in the study and meeting the eligibility criteria assessed at the screening visit will be enrolled in the study. The length of time between screening and treatment will last between 0 days to a maximum of 12 weeks. Subjects who enter the screening phase during a cluster headache episode and meet the study eligibility criteria can immediately enter the treatment phase and may opt to treat their cluster headache episode in the clinic. Subjects who are not in a cluster headache episode, who meet initial screening eligibility criteria, can remain in the screening phase for up to 12 weeks until their next cluster episode begins. Upon initiation of a cluster headache episode, subjects will enter the treatment period. Subjects will be trained on the proper use of the hand-held dispenser containing carbon dioxide (CO2 )calibrated to deliver 0.5 standard liters per minute (SLPM). This dispenser will be provided for use in the clinic or home. Subjects will be instructed to use the nasal CO2 dispenser, 10 seconds/nostril, as needed up to 6 times to treat one attack. Each dose must be separated by 3-5 minutes. Subjects should treat only one attack in a 24-hour period. Subjects may treat up to three cluster headache attacks during the treatment phase of this study. One hour after the first dose, subjects can choose to treat with investigator-approved rescue medication. Subjects will be asked to complete an online diary after the completion of the dosing. Diary assessments will collect pain severity, nasal CO2 usage, acute medication usage, satisfaction of treatment, number of cluster attacks, and unusual symptoms. Subjects will be contacted by phone within 3 days of the first use of the nasal CO2 dispenser to assess adverse events (AEs) and medication usage. A total of 25 subjects will enter the treatment period and be instructed to treat up to 3 cluster headaches with nasal CO2. Within 7 days of treating their last cluster headache episode, subjects will return for an end of study visit.
