Article Synopsis
- An international survey was conducted to identify common sites of cluster headache pain, focusing on pain locations beyond the officially recognized areas of orbital, supraorbital, and temporal regions.
- The study utilized an internet-based questionnaire, collecting data from 1,589 participants, and compared these findings with previous research, cephalic dermatome maps, and brain maps related to pain processing.
- Results indicated that most participants report pain primarily in orbital, periorbital, and temporal areas, while exploring the link between pain locations and other features of cluster headaches, as well as their neurological underpinnings.
Objective: To validate the diagnoses and to investigate epidemiological data from an international, non-clinic-based, and large (n = 1604) survey of participants with cluster headache.
Background: There are several limitations in current epidemiological data in cluster headache including a lack of large non-clinic-based studies. There is also limited information on several aspects of cluster headache, such as pediatric incidence.
Objective: To use 1) newly generated data, 2) existing evidence, and 3) expert opinion to create and validate a new cluster headache screening tool.
Methods: In phase 1 of the study, we performed a prospective study of an English translation of an Italian screen on 95 participants (45 with cluster headache, 17 with other trigeminal autonomic cephalalgias, 30 with migraine, and 3 with trigeminal neuralgia). In phase 2, we performed a systematic review in PubMed of all studies until September 2019 with diagnostic screening tools for cluster headache.
Objective: To determine the pain intensity of cluster headache through a large survey by comparing it to other painful disorders. Furthermore, to investigate the relationship between maximal pain, autonomic, and other clinical symptoms, as well as demographic attributes of cluster headache.
Background: The pain of cluster headache is anecdotally considered to be one of the worst pains in existence.
Objective: To assess the effectiveness and adverse effects of acute cluster headache medications in a large international sample, including recommended treatments such as oxygen, commonly used medications such as opioids, and emerging medications such as intranasal ketamine. Particular focus is paid to a large subset of respondents 65 years of age or older.
Background: Large international surveys of cluster headache are rare, as are examinations of treatments and side effects in older cluster headache patients.
