Active clinical trials for "Headache"

We hypothesised that intravenous infusion of PGI2 induced headache or migraine and cranial vasodilatation in migraineurs.

There is a well-documented but poorly understood relationship between headache disorders (e.g. migraine, cluster headaches, awakening headaches, etc.) and sleep disorders. One hypothesis includes an underlying disorder known as obstructive sleep apnea (OSA) with low overnight oxygen saturations and possibly elevated carbon dioxide levels which result in awakening headache. Bruxism, or grinding of the teeth, has also been anecdotally associated with headache. The converse of these arguments is that the patient may have a primary headache disorder, for example migraine, leading to disordered sleep patterns or insomnia. The true relationship between the two, as alluded above, is unknown. The actual prevalence of the two disorders occurring simultaneously is not known. There have been several small, retrospective studies which have attempted to evaluate this relationship. One of these studies evaluated those patients diagnosed with OSA who were given the standard of care therapy - continuous positive airway pressure (CPAP) - and found that headaches among these patients were improved after using CPAP. Again, this was a small, retrospective study. We propose a study whereby patients who are referred for polysomnography (PSG, or "sleep study") are consented, then surveyed on the presence or absence of headache. A brief questionnaire is followed up with a more detailed questionnaire to characterize whether this headache that the patient has is truly a headache disorder. Following the survey and PSG, the patient's sleep study parameters are evaluated to see whether there are certain correlations between what has been recorded and the particular headache disorder present. Lastly, if the patient was diagnosed with OSA and fitted with a CPAP device, the patient will be queried several weeks later to evaluate whether there was improvement or cessation of the headache disorder.

This study explores lumbar puncture operators stress associated with their performance of the procedure, across three experience levels: Experts, Intermediates, and Novices. The study will investigate the association of this potential stress to patient experienced stress and patient related outcomes of the lumbar puncture procedure.

Cervical epidural steroid injections The hanging drop (HD) technique is commonly used for identifying the cervical epidural space. The hanging drop (HD) technique is using the negative pressure in the epidural space. The subject of debate whether the epidural space exhibits negative pressure. In a previous study, EP might be influenced by body position No report or peer-reviewed literature to demonstrate the cervical epidural pressure (CEP) now. The hypothesis of this study There is a difference in the cervical epidural pressure between in the prone and sitting positions To evaluate this hypothesis, CEPs in the prone and sitting groups were measured and compared in the two groups. Using a closed pressure measurement system Under fluoroscopic guidance.

The purpose of this study is to develop a clinical decision rule for patients seen in the pediatric emergency department for possible intracranial pathology. This a prospective study evaluating patients presenting with headache and migraine. The study is observational and does not impact patient care.

Our main approach in this research is to collect MR data using both a "Routine" and "Fast" brain protocol on the 3 Tesla Siemens Skyra scanner using a 20-Channel Head/Neck Coil to determine if the "Fast" protocol can collect data in less time without compromising patient care.

Description of modalities concerning the patient care of headaches sensible to indometacine.

Headache is the most common complaint to neurologists. In the 80´s and 90's few papers, with limited number of patients, have proposed the association between nasal septum contact and headache. The International Classification of Headaches Disorders proposed specific diagnostic criteria for this entity. With the major use of CT scans, the contact between nasal mucosa and septum is daily observed in many patients without complaint of headache. The purpose of this study is to determine if there is any correlation between nasal and septum mucosa contact and the prevalence of headache. The investigators hypothesized that no correlation will be found using CT scans in a large series of patients.

This study is designed to collect normative data on cervical isometric strength and range of motion to supplement an existing normative data base.

Cluster headache attacks do not occur randomly throughout the day, but have a clear circadian rhythmicity. The aim of this study is to investigate circadian changes of the brain, the autonomic nervous system and pain processing systems.
