Summary: Headache disorders are among the most prevalent medical conditions worldwide. The diagnosis of headache disorders is based on medical history taking. Digital solutions such as natural language processing (NLP) may be of aid to understand the linguistic aspects of headache attack and headache related disability descriptions by patients. Participants will provide a written description of their heada...

Summary: This study collects data from migraine and cluster headache patients during a three-month study. Contextual data (e.g. location or smartphone usage) and physiological variables will be used to assist machine learning algorithms in making predictions on activity, stress and sleep in patients with migraine or cluster headache.

Summary: The purpose of this study is to evaluate the efficacy of eptinezumab in participants with episodic Cluster Headache (eCH)

Summary: Management of postdural puncture headache (PDPH) has always been challenging for anesthesiologists. PDPH not only increases the misery of the patient, but the length of stay and overall cost of treatment in the hospital also increases. Although the epidural blood patch ( EBP ) is an effective way of treating the problem, the procedure itself could cause another inadvertent dural puncture (DP). Mor...

Summary: This study intends to investigate the use of high-dose Vitamin D3 plus a multivitamin in the prevention of cluster headache attacks. Participants can be enrolled anywhere in the United States that has access to one of our participating labs (for blood work - anticipated to be available in most of the USA). The study may include: Screening: Participants may be interviewed, examined, fill out survey...

Summary: The purpose of this study is to investigate the incidence of intravascular injection during trigeminal nerve blocks.

Summary: 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 pa...

Summary: The main purpose of this study is to evaluate the efficacy of erenumab in participants with chronic cluster headache.

Summary: The purpose of this research is to explore the efficacy of rimegepant as a preventative therapy for cluster headache.

Summary: The Will Erwin Headache Research Center Study of Cluster Headache and Trigeminal Neuralgia is a prospective, multicenter, observational research network for subjects with Cluster Headache and/or Trigeminal Neuralgia.

Background: After no official research in humans in the last 40 years, research and therapeutic uses of the serotonergic psychedelic lysergic acid diethylamide (LSD) are now re-recognized and include its use in brain research, alcoholism, anxiety associated with terminal illness, and treatment of headache disorders. Specifically, LSD has been reported to abort attacks, to decrease frequency and intensity of a...

Summary: Cluster headache is a primary headache disorder characterized by attacks of unilateral headache of short duration and severe pain intensity. There is an unmet need to understand the underlying disease mechanisms that will ultimately lead to the development of disease-specific medicines. Until now, it has been suggested that the calcitonin gene-related peptide (CGRP) plays a major role in the initi...
