Filter by:The purpose of this study is to evaluate the effect of topiramate on cerebrovascular reactivity and mean flow velocity to photic stimulation in migraineurs.
The purpose of this study is to investigate the efficacy of e-TNS with the Cefaly® device as an acute treatment for a migraine attack. This open clinical trial will study the acute treatment of migraine using the Cefaly® device, prior to development of a sham-controlled trial.
Opioids are commonly used to treat migraine in North American Emergency Departments. We are comparing efficacy and adverse events of hydromorphone, an opioid, to that of prochlorperazine, a dopamine antagonist with known efficacy in migraine. Prochlorperazine will be combined with diphenhydramine to prevent adverse events.
A prospective, double-blind, randomized, sham-controlled, multicentre investigation.
The purpose of this study is to determine the effects of antihistamine (Clemastin) on migraines triggered by pituitary adenylate cyclase activating peptide-38 (PACAP38) as well as on biochemical markers for mast cell degranulation in migraine patients. Also, to investigate the occurrence of migraine in migraine patients after infusion of PACAP38 in lower dosages than previously investigated. As this has never been done before it is unknown how a lower dose of PACAP38 will affect 1) the incidence of migraine attacks, 2) the accompanying symptoms, 3) head pain characteristics, and 4) debut and duration of migraine attacks. Our three hypotheses are: 1. Pre-treatment with Clemastin reduces PACAP38 sensitivity and inhibits development of migraine in migraine patients. 2. Clemastin inhibits the increase in plasma concentration of TNF-alpha, histamine and tryptase after PACAP38-infusion. 3. PACAP38 in lower dosages (4, 6 and 8 pmol/kg/min) induces migraine in migraine patients.
Ketorolac is an evidence-based, first-line acute migraine therapy that is commonly used in the pediatric population; however, it is typically administered by the intravenous (IV) or intramuscular (IM) routes, both of which require a painful and distressing needle stick to administer. The intranasal (IN) route is a painless and effective way of administering analgesics, including ketorolac: IN ketorolac has been shown to be an effective analgesic in adults for painful conditions, including acute migraine headaches. However, IN ketorolac has been understudied in children, and it is not known how effective it is compared to IV ketorolac, which is currently the most common way of administering ketorolac to children. If IN ketorolac is shown to be no less effective than IV ketorolac, IN ketorolac may be a viable and painless alternative to effectively treat acute migraine headaches in children. Therefore, our primary aim is to demonstrate that IN ketorolac is non-inferior to IV ketorolac for reducing pain in children with acute migraine headaches.
According to the peripheral trigger theory of migraine headaches, nociceptive inputs from irritated or compressed cranial nerve branches can lead to neurovascular changes in the brain that cause migraine headaches. Advanced treatments aimed at deactivating the peripheral trigger points can be administered to patients who have failed medical management of migraines. Those accepted advanced treatments include botulinum toxin A injection in order to temporarily paralyze muscles causing nerve compression, and surgery to release those compression points permanently. An advantage of surgery is the ability to release non-muscular causes of nerve compression, such as fascial bands or intersecting arteries. Botulinum toxin A injection into trigger sites has been shown in multiple studies to be effective at reducing the frequency and severity of migraine headaches, and is a very commonly administered treatment for refractory migraines. It is approved by the FDA for the treatment of chronic migraines. Similarly, surgical decompression of trigger sites has previously been shown to have superior clinical outcomes to medical management, through a randomized, blinded controlled-trial performed at Case Western Reserve in 2009. Patients either received actual decompression of the trigger sites, or sham surgery (exposure and visualization of the trigger sites, without decompression). At one-year follow-up, the group who underwent actual surgery demonstrated a statistically higher proportion with significant improvement in their migraines (83.7% vs. 57.7%, p=0.014), and with complete elimination of their migraines (57.1% vs. 3.8%, p<0.001). Several other reports have confirmed the good clinical outcomes of surgery demonstrated in this trial, and surgical decompression is now commonly performed by several surgeons around the United States. Prognostic factors predicting the success of surgical decompression in migraine headache treatment include older age of migraine onset, visual symptoms/aura, and 4-site decompression. Factors predicting failure of surgery include excessive operative blood loss, and surgery on only one or two trigger sites. One criticism of the studies on peripheral trigger decompression surgery for migraines has been that most of the results have originated from the same institution (Case Western Reserve), and from the same author (Guyuron). While several studies at other institutions have demonstrated positive outcomes of peripheral trigger decompression, these have only included a small number of patients. In addition, the sham surgery randomized-controlled trial has been criticized for not clarifying any prior treatments that patients had undergone before peripheral trigger deactivation, and for not showing how medication use patterns changed after surgery. Another criticism of that study was the fact that patients were examined by neurologists before the study but not after the study, and that surgery was performed on some patients with episodic migraines, who are known to not benefit from botulinum toxin. It is unclear what migraine types are most likely to benefit from surgical decompression. The investigators' goal is to perform a multi-center, prospective trial to demonstrate the effectiveness of peripheral trigger decompression in the treatment of migraine headaches, which would address the criticisms mentioned above. The main aim is to demonstrate that the positive results demonstrated by Guyuron et al are reproducible at other institutions and by other surgeons using similar techniques on different patient populations.
The presented study aims to compare effectivity of propranolol with effectivity of venlafaxine in escalating dose in subjects with vestibular migraine (VM) over a period of 12 weeks. The study population consisted of subjects diagnosed definite VM according to criteria of Bárány Society and Migraine Classification Subcommittee of the International Headache Society (IHS). Effectivity of therapy was measured by Dizziness Handicap Inventory (DHI), number of vertiginous attack of last month and visual analogue scale (VAS) reported dizziness related Quality of Life (QOL). Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) were also used to determine psychiatric improvement played role in response to therapy in venlafaxine treatment arm.
Migraine in adolescents is common and effective and safe preventive treatments are needed. This is a pilot randomized controlled trial of melatonin versus placebo for migraine prevention in adolescents 12-17 years old.
The main objective of this study was to assess the safety and efficacy of the Cefaly® e-TNS device as a prophylactic treatment of chronic migraine in adult patients.
