Active clinical trials for "Headache"

Studying Pituitary adenylate cyclase-activating peptide 27 (PACAP27) effects on extra- and intracerebral arteries assessed by MRA on healthy volunteers.

Healthy participants vill randomly be allocated in a 2:1 order to receive 1 mg levcromakalim or placebo (isotonic saline) for 20 min. The investigator here examine the effect of levcromakalim infusion on the MMA and the MCA circumference over several hours using a high resolution MRA technique in a randomized, double-blind placebo-controlled design in healthy volunteers. The investigator hypothesized that levcromakalim induces dilatation of cranial arteries.

The objective of this study is to compare the effectiveness of a personalized patient education program to the current hospital education and evaluate its impact using patient satisfaction scores. The investigators hypothesize that a personalized patient education intervention will increase patient's understanding of their diagnosis and satisfaction with the care as reflected in the survey results.

Adenosine is a nucleoside that plays a role in both vascular and nociceptive systems, and it has been proposed that adenosine may cause headache in particularly sensitive subjects. Thus, considerable evidence implied that adenosine plays a role in migraine pathophysiology, it is still unknown if intravenous adenosine infusion provokes migraine attacks in healthy subject or in migraine patients. Furthermore, adenosine's effects on the cerebral hemodynamic remains unknown. This study aims to clarify a possible coherence between adenosine and headache/migraine. In general, the study will contribute to a greater understanding of migraine pathogenesis and possibly lead to development of specific migraine treatment.

Cervicogenic headache (CgH) is a distinct form of headache and accounts for 17.8% of all headaches and the prevalence rate is between 0.4% and 20%. A guide to health and safety in the office handbook by common wealth of Australia (2008) suggested the ergonomic guidance and interventions for preventing and treating musculoskeletal disorder (MSD) injuries in the office workers. Also, It has been estimated that 34% of US citizens receive some sort of physiotherapy for CgH each year. However, no studies have compared and investigated the combined and individual effects of workstation ergonomics, physiotherapy and patient education for improving cervicogenic headache and work ability in office workers.

Background: Tension Type Headache (TTH) is highly frequent and is of great socio-economic importance. Andersen et al. 2008 has shown that maximal muscle strength is reduced in women with trapezius myalgia. It is shown that specific strength training leads to prolonged pain relief. Aim:Test: To investigate the impact of TTH on shoulder, and neck muscle strength in patients with TTH compared to healthy controls. Intervention: To investigate the effect of specific strength training on patients with TTH compared with control group, receiving training in ergonomics. Method: Test part. 60 tension headache patients, 30 healthy. Muscle testing of neck and shoulder. Testing conducted by blinded research assistant. Intervention group: 60 patients with tension headache randomly assigned to the intervention group or control group. Intervention with specific strength training program runs for 10 weeks. The control group will be trained in ergonomics. 3 months follow up.

Postdural puncture headache (PDPH) is defined, according to the International Headache Society, as any headache develops within 5 days after a lumbar puncture. It worsens within 15 minutes after sitting or standing and improves within 15 minutes after lying. For preventing PDPH, there are some uncomfortable practices for patients (fluid supplementation and bed rest) and expensive for hospital (time spend for information and management of fluid intake). Patients are usually advised by nurses. If "bed rest" is not effective in prevention of PDPH, "fluid supplementation" is not an advice based on any evidence but only on routine. By this trial, the investigators want to evaluate the scientific value of this advice, in the standard patient care. The primary objective of this study is to compare oral hyperhydration (2 liters during 2 hours after lumbar puncture - the most common routine according to an internal pilot survey) versus no advice about the fluid intake to prevent the PDPH. The second objective is to observe the day of apparition of PDPH, between day 0 and day 5.

Cervical spine manipulation (CSM) is utilized by many health care practitioners in the management of patients with neck pain and headache. How CSM works is not understood however, most researchers agree that there is likely a combination of mechanical, neurophysiological and placebo effects. This study will test for possible neurophysiological effects by examining for changes in a person's ability to reposition their head and neck in space, and maintain their balance following CSM.

A pharmacokinetic drug interaction study of erenumab and an oral contraceptive containing progestin and estrogen.

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: Provoking ECH patients in bout with CGRP triggers cluster headache attacks Provoking ECH patients in remission with CGRP does not trigger cluster headache attacks Provoking chronic cluster headache patients with CGRP triggers cluster headache attacks more often than in ECH patients.
