Filter by:Migraine has been described as one of the most common neurological diseases, with high social and economic impact. Despite the high prevalence, the pathophysiology of migraine is still unknown, several studies have been developed in order to advance the understanding of the pathophysiological mechanisms of the disease which are not yet entirely elucidated. The aim of this study is to observe the effects of transcranial direct current stimulation (tDCS), applied in the visual cortex, on neurophysiological and clinical measures (frequency, intensity, duration of attacks and severity of pain) in migraine patients.
Patients who report that exposure to bright light or strenuous physical activity will induce migraine aura will be provoked using one or both of these methods. Followingly the patients will be examined by functional MRI. Íf the patients develop migraine headache, MR angiography will be performed as well. The primary study hypothesis is that the functional MRI signal will show features similar to those of the electrophysiological phenomenon of cortical spreading depression.
This study will examine the combined effects of a continuous oral contraceptive (OC) regimen with supplemental estradiol therapy on headache severity and occurrence in subjects with documented Menstrually Associated Migraines (MAMs). The subjects enrolling in the study will have cyclic menses either due to spontaneous ovulation or use of cyclic hormonal contraception (pill, patch, or ring). Enrolled subjects will start a continuous OC regimen following two baseline menstrual cycles. If breakthrough bleeding/spotting (BTB/BTS) occurs, the subject will institute a 4-day hormone-free interval (HFI). In an attempt to prevent/lessen the severity of headache during the HFI, subjects will be randomized to oral estradiol or placebo during this period. If no BTB/BTS occurs after 80 days of continuous pills, the subject will institute a 4-day HFI during which they will be randomized into estradiol or placebo groups. The purpose of this research study is to examine the effects of continuous oral contraceptive pills and oral estradiol on headaches that occur around the time of your period. Many woman take continuous oral contraceptive pills (OC) and when OCs are stopped they may get headaches. This study will examine if taking estradiol around the time of the period will affect the headache, and how it will be affected. This study is a prospective trial. A subject's participation will last approximately 32 weeks.
Migraine in children and adolescents can be associated with low serum levels of coenzyme q10, the key-enzyme of mitochondrial energy production.During migraine attacks inflammation is an important issue. Based on a double-blind placebo-controlled trial with coenzyme q10 in adults it is hypothesized that daily supplementation of coenzyme q10 as well as different antioxidative phytochemicals (from berries) and specific minerals and vitamins are able to reduce the "days with migraine" as primary parameter (open clinical trial).
This is a double-blinded placebo study, examining the efficacy of Sumatriptan with Naprosyn in the treatment of migraine with aura.
The following study is being conducted to explore the safety and effectiveness of a new chemical entity called NXN-188 in subjects with a history of migraine with aura. In this study subjects will treat two attacks of migraine with aura during the aura phase - once with placebo and once with NXN-188.
Migraine headache occurs frequently in women more than men and is associated with symptoms not only of significant pain but also of symptoms typically including of photophobia, phonophobia, nausea and vomiting. Many migraine patients report difficulty in cognition from lack of concentration, difficulty in word finding or inability to remember. Many of these cognitive symptoms seem to be independent of the pain intensity and may occur completely separately from the headache pain but can be disabling. It is likely that the frequency and importance of cognitive symptoms associated with migraine are underreported. The Mental Efficacy Workload Test (MEWT) is a computerized battery that is designed to be an efficient and accurate measure of cognition during migraine headache. Treximet is a new migraine treatment recently FDA approved for the treatment for the relief of acute migraine that may be effective for the cognitive symptoms for migraine patients who have a history of cognitive dysfunction during a migraine headache. The primary efficacy parameter is to evaluate the effectiveness of treatment with Treximet versus placebo in patients with acute migraine headache measuring neuropsychological function using the MEWT during the migraine and comparing that score with a prior MEWT score when the patient had no migraine symptoms. A double blind, placebo-controlled, crossover study was chosen so that each patient may be her or his own control. It is the intent of this study to determine the type and intensity of cognitive dysfunction associated with migraine headache and to what extent that Treximet may relieve the cognitive dysfunction in a safe and effective manner.
We hypothesised that intravenous infusion of PGI2 induced headache or migraine and cranial vasodilatation in migraineurs.
The purpose of this study is to evaluate the use of nutritional supplementation and dietary management for the reduction in frequency, duration, and intensity of migraine headache pain.
: Headaches are a common complaint presenting to the emergency department (ED), accounting for 1-2% of all ED visits, with migraines as the second most common primary headache syndrome. Patients that ultimately present to the ED have failed outpatient therapy and exhibit severe and persistent symptoms. Treatment options have been traditionally with a parenteral opiod, generally Demerol. Unfortunately, patients with chronic painful conditions like migraines have been prone to dependency. In 1986, a nonopioid, compazine was noted serendipitously to relieve migraine headache pain. 1 Nonopioid regimens have evolved as standard therapy in the treatment of migrainne headache in the ED. Today, there are a number of nonopioid treatment options, but not without their own individual concerns. Ergotamine and dihydroergotamine are effective, but commonly cause nausea and vomiting. Sumatriptan is expensive has recurrence rate, is ineffective in about 20-30%, and is contra-indicated in patients with cardiac disease. Metoclopramide, a dopamine receptor antagonist, commonly used as an anti-emetic agent, has been widely studied for use with acute migraines. Its side effects include drowsiness and dystonic reactions. Compazine has been successfully used to treat migraine headaches for the past several decades, and has been accepted as standard treatment of headaches in the ED. 2 Its side effect profile includes extrapyramidal effects, dysphoria, drowsiness and akathisias. The ideal medication for treating headaches would have no addictive properties, few side effects, quick onset, be highly effective and have a low rate of recurrence. Somatostatin is known to have an inhibitory effect on a number of neuropetides, which have been implicated in migraine. Native somatostatin is an unstable compound and is broken down in minutes, but octreotide, a somatostatin analogue has a longer half life. Intravenous somatostatin has been shown to be as effective as ergotamine in the acute treatment of cluster headache. 3 The analgesic effect of octreotide with headaches associated with growth hormone secreting tumor has been established. 4 Five somatostatin receptors have been cloned with octreotide acting predominantely on sst2 and sst5. The distribution of sst2 within the central nervous system strongly suggests that this particular somatostatin receptor has a role in cranial nociception, being highly expressed in the trigeminal nucleus caudalis and periaqueductal grey. Kapicioglu et.al performed a double blind study comparing octreotide to placebo in treating migraine. They found there to be a significantly greater relief of pain with octreotide at 2 and 6 hours compared to placebo (76% vs 25%, p<0.02). They noted that 47% of those in the octreotide group had complete relief compared to no patients in the placebo group. They went on to note that those patients in the octreotide group had earlier relief of symptoms and no side effects. The only minor adverse event related to the administration of octreotide was a local reaction in 3 patients (18%). In a study performed recently in Netherlands, no clinically relevant changes in vital signs, routine chemistry, and urinalysis were observed with octreotide use. Electrocardiogram analyses showed no newly occurring or worsening of known cardiac abnormalities 2 and 24 h after injection with octreotide. 5 Levy et. al also compared octreotide to placebo in a double blinded study but found no difference. This was a poorly designed study, in that the patients treated themselves at home with an injection of either placebo or octreotide for 2 episodes of headache and recorded their level of pain relief at 2 hours. Matharu et. al also performed a double blind study comparing octreotide to placebo, but looking at cluster headaches rather than migraines. They found there to be a significant improvement with the use of octreotide over placebo (52% vs 36%). At Darnall Army Community Hospital the cost of 100 mcg Octreotide and10 mg Compazine, is $10.46, $2.02-8.00, respectively.
