The third edition of Migraine Clinical Trials Guidelines is now available in the IHS journal Cephalalgia, which is published by SAGE. The new guidelines represent an expert consensus summary, and recommend a contemporary, standardized, and evidence-based approach to investigators conducting and reporting randomised, controlled migraine clinical trials. Migraine clinical research has increased exponentially since the last set of guidelines was published. Clinical researchers and pharmaceutical companies have accumulated further experience, and the trend is towards large, multi-national and multi-centre studies. Given these developments, it was timely to bring the guidelines up to date. The IHS stresses that it endorses adherence to the guidelines unless there is scientific justification to deviate from them. They represent research practice parameters and are the highest level in the hierarchy of evidence-based recommendations in the absence of published standards of research practice.  Headache News 2012-01-24T20:23:00+00:00 http://www.headachecare.net/migraine/more/276/ http://www.headachecare.net/migraine/more/276/#When:08:21:01Z Kids who have a concussion or other traumatic brain injury are more likely to develop headaches for up to a year afterward than children who have had a bodily injury, according to a new study. While not entirely surprising, the results point to a difficult long-term problem for kids and their parents because adequate treatments are lacking, researchers say. “It’s an issue because they may have problems with sleep, and the headaches can make it harder to concentrate,” said lead author Dr. Heidi Blume at Seattle Children’s Research Institute.

The research, published in the journal Headache, also hints that the relationship may go both ways, and people with clinical depression could have a higher risk of developing migraines, but that finding could have been due to chance, the researchers say. Nonetheless, lead author Geeta Modgill, who was at the University of Calgary while conducting the work, told Reuters Health that migraine and depression sufferers should know the signs of both ailments since each might be at a higher risk for the other condition.

About 30 percent of people with recurrent migraines have sensory disturbances shortly before their headache hits, known as aura, but these are usually visual, such as flashes of light or blind spots. Tingling sensations or numbness, or difficulty speaking or understanding language, may also appear. But the study, conducted by Matthew Robbins and colleagues at the Montefiore Headache Center in New York, found that a small number of people described smelling scents in conjunction with their headaches.

New invasive procedures, such as hypothalamic deep brain stimulation and bilateral occipital nerve stimulation, may help patients with chronic refractory headache. This is one of the conclusions reached by Charly Gaul and co-authors from the Department of Neurology at the University Medical Center Essen in the current issue of Deutsches Ärzteblatt International. Cluster headache is the most common trigemino-autonomic headache, affecting some 120,000 people in Germany. Typically, patients suffer unilateral short attacks, which are accompanied by restlessness. The causes of cluster headache are not clear. Men are affected more often than women, with a ratio of 3.5:1.

Earlier this summer, the FDA said it wanted to see an even greater rate of migraine improvement for patients in the study using the device compared with those in a control group. The new European device treats migraines by stimulating nerves at the base of the head with electrical pulses, which seems to block pain signals from reaching the brain, St. Jude said. There are currently few treatments for people who suffer serious recurring migraine headaches. The therapy for this condition involves delivering mild electrical pulses to the occipital nerves that are located just beneath the skin at the back of the head. A small electrical lead or leads are placed under the skin and are connected to the neurostimulator, which produces the stimulation.  Headache News 2011-09-14T08:50:00+00:00 http://www.headachecare.net/migraine/more/271/ http://www.headachecare.net/migraine/more/271/#When:06:37:00Z A painkilling, anti-inflammatory drug may help prevent headaches in Muslims fasting from dawn to dusk for Ramadan, according to a study from Israel—where a “Yom Kippur headache” is also known. About four in every ten people who abstain from food and water all day during the month-long Ramadan period get headaches, said the study, published in the journal Headache. This year, Ramadan began on August 1. “Religious fasting is associated with headache,” wrote lead researcher Michael Drescher, from Hartford Hospital in Connecticut, the United States, referring to Ramadan and Judaism’s Yom Kippur, when people fast for 25 hours.

Compounds in foods and beverages (chocolate, wine, citrus, etc) considered as migraine triggers include tyramine, phenylethylamine and possibly histamine and phenolic compounds. Avoiding those triggers may significantly reduce the frequency of migraines in some patients. However, only a small percentage of patients in one study became headache-free simply by excluding those foods, epidemiological studies are pointing out that genetic factors may be an underlying cause. Discrepancies in the way people are reacting to wine intake, and whether or not it triggers migraine, may be potentially explained by genetic polymorphisms in specific enzymes related to metabolism Alcoholic drinks are a migraine trigger in about one third of patients with migraine in retrospective studies on trigger factors. Many population studies show that patients with migraine consume alcohol in a smaller percentage than the general population. Research has shown a decreased prevalence of headache with increasing number of alcohol units consumed. The classification criteria of alcohol-related headaches remain problematic. An excellent paper from The Headache Center in Empoli, Italy by Panconesi A et al (Curr Pain Headache Rep (2011) )15:177-184 summarizes the scientific data relating to alcohol and migraine headaches. The factors that trigger an attack of migraine, or of other headaches as well, are poorly understood.  Headache News 2011-06-15T01:29:00+00:00 http://www.headachecare.net/migraine/more/269/ http://www.headachecare.net/migraine/more/269/#When:07:50:01Z The discovery of a gene for migraine holds great promise in the quest for new approaches—possibly even a pill—for preventing the disease, says a panel of experts presenting data at the annual scientific meeting of the American Headache Society. So far, there is no therapy that prevents an attack. Guy A. Rouleau, MD, whose Canadian and British research team was first to sequence the gene for migraine last fall, says for the first time since the discovery of the triptans in the 1980s, investigators seeking to develop new migraine therapies are excited about the possibility of preventive drugs for migraine. Triptans act by constricting blood vessels in the brain which in turn inhibit pain receptors which can block migraine in some patients. They are e not considered preventative therapies. “We may be moving toward developing about a pill that would block the brain’s pain channel that reacts to stimulation and causes pain in migraine,” says Dr. Rouleau. ‘Sequencing the gene not only allows us to understand the disease – it also opens understanding of the pain pathways that trigger migraine pain.” Dr. Rouleau is director of the CHU Sainte-Justine Research Center and Full Professor in the Department of Medicine of the Université de Montréal Headache News 2011-06-02T07:50:01+00:00 http://www.headachecare.net/migraine/more/268/ http://www.headachecare.net/migraine/more/268/#When:07:13:01Z For the first time, researchers have shown why precision-tinted lenses reduce headaches for migraine sufferers, a finding that could help improve treatment options for patients battling the debilitating ailment. Jie Huang of Michigan State University’s Department of Radiology used functional magnetic resonance imaging, or fMRI, to reveal how precision-tinted lenses normalize brain activity in patients with migraine headaches, preventing such attacks. Huang’s research appears in the current edition of the journal Cephalalgia, published by SAGE. While tinted lenses are increasingly used for migraine sufferers, until now the science behind the effects was unclear. The team led by Huang showed how colored glasses - tuned specifically to each migraine sufferer - work by normalizing the activity in the brain’s visual cortex, which is responsible for processing visual information and is located in the back of the brain.
