View clinical trials related to Cluster Headache.
Filter by:The objective of this study is to survey patients with cluster headache about treatment effectiveness and their views on treatments. Participants will complete one brief questionnaire online.
The study is an investigator-initiated, prospective, randomized, placebo-controlled, double blind clinical trial that aims to investigate the effect of transcutaneous electrical nerve stimulation (TENS) and occipital nerve stimulation (ONS) on attack frequency and severity in patients with chronic cluster headache (CH). Study outline Month 1: Baseline. Establishment of a baseline profile of the participants CH attacks (severity, duration, medicine utilization etc), health-related quality of life (QoL) and symptoms of anxiety and depression. No active treatment. Follow-up visit after 30 days. Months 2-4: TENS period. All participants will receive TENS-treatment. Clinical follow-up visit by the end of month four. Months 5-7: Double-blinded, randomized experimental period. All participants will have an ONS-system (lead, impulse generator) implanted and will be randomized 1:1 to receive either 1) burst (paresthesia-free) ONS or 2) placebo (deactivated ONS system). Clinical follow-up visit by the end of month seven. Months 8-10: Open label period. All participants will receive tonic (conventional, paresthesia-inducing) ONS. Clinical follow-up visit by the end of month ten. During every study phase each participant will fill out a weekly electronic headache registration as well as answering questionnaires regarding health-related quality of life and symptoms of anxiety and depression before every follow-up visit.
This study investigates molecular and physical biomarkers of headaches in order to better understand mechanisms of these diseases. There are 3 main parts: 1. Use of capsaicin (active ingredient in hot chili peppers) to trigger release of calcitonin gene related peptide - the hypothesis is that this will be different in headache subjects compared to controls (and if so might be used to predict how these patients will respond to certain medications that modulate calcitonin gene-related peptide). Subjects will be given capsaicin as a cream applied to the forehead or the inner nostril, or a hot sauce that is ingested. 2. Use of capsaicin to trigger eye watering - the hypothesis is that oxygen gas will slow down the amount of eye watering. Cluster headache patients respond very powerfully to oxygen gas but to very little else. The mechanism for oxygen is unknown but in rodents there is data that it works on the parasympathetic / lacrimal gland system. This study translates rodent data into humans in a non-invasive way to confirm the mechanism of this very effective treatment. 3. Use of ice water to trigger headaches - brain freeze causes a very short-lived but intense headache that may cause similar biomarker release as other headache disorders. This may be a useful human model for other headache disorders.
Monitor the safety and performance of the Pulsante Microstimulator System.
The primary objective of the study is to demonstrate the safety and efficacy of SPG stimulation with the ATI Neurostimulation System when used to treat acute cluster attacks in chronic cluster headache patients.
