79-485: The combination is used to treat the symptoms of migraine , both to relieve headache (the analgesic) and to treat associated nausea and vomiting (the antiemetic). In addition to its direct anti-emetic effect metoclopramide also stimulates gastric emptying ( prokinetic ), which is often delayed during migraine attacks, and accelerates the absorption of paracetamol. However the improvement in paracetamol absorption has been questioned. The combination of metoclopramide to

158-485: A neuromodulator , may be involved. Released after the progressive cleavage of adenosine triphosphate (ATP), adenosine acts on adenosine receptors to put the body and brain in a low activity state by dilating blood vessels and slowing the heart rate, such as before and during the early stages of sleep. Adenosine levels have been found to be high during migraine attacks. Caffeine's role as an inhibitor of adenosine may explain its effect in reducing migraine. Low levels of

237-454: A serotonin syndrome (a syndrome of changes in mental status, autonomic instability, neuromuscular abnormalities, and gastrointestinal symptoms), whereas scientific studies indicate there is no potential for life-threatening serotonin syndrome in patients taking triptans and SSRI or SNRIs at the same time, although the FDA has officially stated otherwise. Combining triptans with ergot alkaloids

316-436: A 34–51% genetic influence on the likelihood of developing migraine. This genetic relationship is stronger for migraine with aura than for migraine without aura. It is clear from family and populations studies that migraine is a complex disorder , where numerous genetic risk variants exist, and where each variant increases the risk of migraine marginally. It is also known that having several of these risk variants increases

395-402: A castle. Usually the lines are in black and white but some people also see colored lines. Some people lose part of their field of vision known as hemianopsia while others experience blurring. Sensory aura are the second most common type; they occur in 30–40% of people with auras. Often a feeling of pins-and-needles begins on one side in the hand and arm and spreads to the nose–mouth area on

474-451: A continuum of different attack frequencies and associated levels of disability." For those with occasional, episodic migraine, a "proper combination of drugs for prevention and treatment of migraine attacks" can limit the disease's impact on patients' personal and professional lives. But fewer than half of people with migraine seek medical care and more than half go undiagnosed and undertreated. "Responsive prevention and treatment of migraine

553-407: A distinct clinical entity. Disease burden can range from episodic discrete attacks to chronic disease. Migraine is believed to be caused by a mixture of environmental and genetic factors that influence the excitation and inhibition of nerve cells in the brain. An incomplete "vascular hypothesis" postulated that the aura of migraine is produced by vasoconstriction and the headache of migraine

632-474: A headache may be a type of migraine or are at least a precursor to migraine attacks. These episodes of pain may or may not follow a migraine-like prodrome and typically last minutes to hours. They often occur in those with either a personal or family history of typical migraine. Other syndromes that are believed to be precursors include cyclical vomiting syndrome and benign paroxysmal vertigo of childhood . Other conditions that can cause similar symptoms to

711-560: A higher potential for central nervous side effects. Donitriptan and avitriptan were never marketed. The history of triptans began with the proposed existence of then unknown serotonin (5-hydroxytryptamine, 5-HT). In the late 1940s two groups of investigators, one in Italy and the other in the United States, identified a substance that was called serotonin in the US and enteramine in Italy. In

790-525: A life-changing disorder of chronic pain, sensory amplification, and autonomic and affective disruption. This progression, sometimes termed chronification in the migraine literature, is common, affecting 3% of migraineurs in a given year, such that 8% of migraineurs have chronic migraine in any given year." Brain imagery reveals that the electrophysiological changes seen during an attack become permanent in people with chronic migraine; "thus, from an electrophysiological point of view, chronic migraine indeed resembles

869-475: A migraine diagnosis. It is believed that a substantial number of people with the condition remain undiagnosed. The diagnosis of migraine without aura, according to the International Headache Society , can be made according the "5, 4, 3, 2, 1 criteria", which is as follows: If someone experiences two of the following: photophobia, nausea, or inability to work or study for a day, the diagnosis

948-456: A migraine headache include temporal arteritis , cluster headaches , acute glaucoma , meningitis and subarachnoid hemorrhage . Temporal arteritis typically occurs in people over 50 years old and presents with tenderness over the temple , cluster headache presents with one-sided nose stuffiness, tears and severe pain around the orbits , acute glaucoma is associated with vision problems, meningitis with fevers , and subarachnoid hemorrhage with

1027-552: A needle-free injection system that works with air pressure. All triptans are contraindicated in patients with cardiovascular diseases ( coronary spasms , symptomatic coronary artery disease , after a heart attack or stroke , uncontrolled hypertension , Raynaud's disease , peripheral artery disease ). Most triptans are also contraindicated during pregnancy and breastfeeding and for patients younger than 18; but sumatriptan and zolmitriptan nasal sprays are also approved for youths over 12. In spite of expert opinion and evidence to

1106-492: A never-ending migraine attack." Severe migraine ranks in the highest category of disability, according to the World Health Organization, which uses objective metrics to determine disability burden for the authoritative annual Global Burden of Disease report. The report classifies severe migraine alongside severe depression, active psychosis, quadriplegia, and terminal-stage cancer. Migraine with aura appears to be

1185-432: A number of other application forms are marketed: suppositories , a subcutaneous injection, an iontophoretic transdermal patch, which uses low voltage controlled by a pre-programmed microchip to deliver a single dose of sumatriptan through the skin within 30 minutes; a drug-device combination containing sumatriptan powder that is "breath powered" allowing the user to blow sumatriptan powder in to their nostrils; as well as

1264-433: A pharmacological basis. After cloning two distinct genes for 5-HT 1B and 5-HT 1D receptors, a better insight into distribution and expression in different tissues was gained, except in brain tissue where they are overlapping in several areas. Most mammalian species, including humans, have 5-HT 1D binding sites widely distributed throughout the central nervous system . 5-HT 1D receptors are found in all areas of

1343-434: A risk factor for ischemic stroke doubling the risk. Being a young adult, being female, using hormonal birth control , and smoking further increases this risk. There also appears to be an association with cervical artery dissection . Migraine without aura does not appear to be a factor. The relationship with heart problems is inconclusive with a single study supporting an association. Migraine does not appear to increase

1422-542: A role. These hormonal influences seem to play a greater role in migraine without aura. Migraine episodes typically do not occur during the second and third trimesters of pregnancy, or following menopause. Between 12% and 60% of people report foods as triggers. There are many reports that tyramine  – which is naturally present in chocolate, alcoholic beverages, most cheeses, processed meats, and other foods – can trigger migraine symptoms in some individuals. Monosodium glutamate (MSG) has been reported as

1501-535: A trigger for migraine, but a systematic review concluded that "a causal relationship between MSG and headache has not been proven... It would seem premature to conclude that the MSG present in food causes headache". A 2009 review on potential triggers in the indoor and outdoor environment concluded that while there were insufficient studies to confirm environmental factors as causing migraine, "migraineurs worldwide consistently report similar environmental triggers". Migraine

1580-472: A trigger. Common triggers quoted are stress, hunger, and fatigue (these equally contribute to tension headaches ). Psychological stress has been reported as a factor by 50–80% of people. Migraine has also been associated with post-traumatic stress disorder and abuse. Migraine episodes are more likely to occur around menstruation . Other hormonal influences, such as menarche , oral contraceptive use, pregnancy , perimenopause, and menopause , also play

1659-695: A very fast onset. Tension headaches typically occur on both sides, are not pounding, and are less disabling. Those with stable headaches that meet criteria for migraine should not receive neuroimaging to look for other intracranial disease. This requires that other concerning findings such as papilledema (swelling of the optic disc) are not present. People with migraine are not at an increased risk of having another cause for severe headaches. Management of migraine includes prevention of migraine attacks and rescue treatment . There are three main aspects of treatment: trigger avoidance, acute (abortive), and preventive (prophylactic) control. "Migraine exists on

1738-455: Is a key pathophysiological phenomenon in migraine. It is debatable whether sensitization starts in the periphery or in the brain. Cortical spreading depression , or spreading depression according to Leão , is a burst of neuronal activity followed by a period of inactivity, which is seen in those with migraine with aura. There are a number of explanations for its occurrence, including activation of NMDA receptors leading to calcium entering

1817-658: Is a needle-free delivery of injectable sumatriptan that was approved in the US by the FDA in July 2009. Sumatriptan became available as a generic in the US in late 2009. It used to be sold over-the-counter in Romania under the Imigran brand; however, as of August 2014 prescription is required. Zecuity, a sumatriptan transdermal patch, was approved by the US FDA in January 2013. The sumatriptan nasal powder

1896-417: Is another distinguishing feature. Up to one-third of people with migraine experience aura , a premonitory period of sensory disturbance widely accepted to be caused by cortical spreading depression at the onset of a migraine attack. Although primarily considered to be a headache disorder, migraine is highly heterogenous in its clinical presentation and is better thought of as a spectrum disease rather than

1975-452: Is believed to be primarily a neurological disorder, while others believe it to be a neurovascular disorder with blood vessels playing the key role, although evidence does not support this completely. Others believe both are likely important. One theory is related to increased excitability of the cerebral cortex and abnormal control of pain neurons in the trigeminal nucleus of the brainstem . Sensitization of trigeminal pathways

2054-468: Is contraindicated because of the danger of coronary spasms. In a study from Harvard Medical School and the University of Florida College of Medicine involving 47,968 patients and published on 26 February 2018, concomitant use of a selective serotonin reuptake inhibitor or selective norepinephrine reuptake inhibitor for depression with a triptan for migraine did not demonstrate an increased risk of

2133-408: Is different from the other triptans because it is converted to an active N-desmethyl metabolite which has higher affinity for the 5-HT 1D and 5-HT 1B receptors; both substances have a biological half-life of 2 to 3 hours. In studies, newer triptans are mostly compared to sumatriptan. They are better than sumatriptan for their longer half-life in plasma and higher oral bioavailability , but have

2212-440: Is incredibly important" because evidence shows "an increased sensitivity after each successive attack, eventually leading to chronic daily migraine in some individuals." Repeated migraine results in "reorganization of brain circuitry", causing "profound functional as well as structural changes in the brain." "One of the most important problems in clinical migraine is the progression from an intermittent, self-limited inconvenience to

2291-494: Is more likely. In those with four out of five of the following: pulsating headache, duration of 4–72 hours, pain on one side of the head, nausea, or symptoms that interfere with the person's life, the probability that this is a migraine attack is 92%. In those with fewer than three of these symptoms, the probability is 17%. Migraine was first comprehensively classified in 1988. The International Headache Society updated their classification of headaches in 2004. A third version

2370-684: Is most pronounced in migraine without aura. Worldwide, migraine affects nearly 15% or approximately one billion people. In the United States, about 6% of men and 18% of women experience a migraine attack in a given year, with a lifetime risk of about 18% and 43% respectively. In Europe, migraine affects 12–28% of people at some point in their lives with about 6–15% of adult men and 14–35% of adult women getting at least one attack yearly. Rates of migraine are slightly lower in Asia and Africa than in Western countries. Chronic migraine occurs in approximately 1.4–2.2% of

2449-463: Is not in phase with the pulse . In more than 40% of cases, however, the pain may be bilateral (both sides of the head), and neck pain is commonly associated with it. Bilateral pain is particularly common in those who have migraine without aura. Less commonly pain may occur primarily in the back or top of the head. The pain usually lasts 4 to 72 hours in adults; however, in young children frequently lasts less than 1 hour. The frequency of attacks

2528-426: Is produced by vasodilation . However, the vasoconstrictive mechanism has been disproven, and the role of vasodilation in migraine pathophysiology is uncertain. The accepted hypothesis suggests that multiple primary neuronal impairments lead to a series of intracranial and extracranial changes, triggering a physiological cascade that leads to migraine symptomatology. Initial recommended treatment for acute attacks

2607-454: Is unknown. However, it is believed to be related to a mix of environmental and genetic factors. Migraine runs in families in about two-thirds of cases and rarely occur due to a single gene defect. While migraine attacks were once believed to be more common in those of high intelligence, this does not appear to be true. A number of psychological conditions are associated, including depression , anxiety , and bipolar disorder . Success of

2686-436: Is variable, from a few in a lifetime to several a week, with the average being about one a month. The pain is frequently accompanied by nausea, vomiting, sensitivity to light , sensitivity to sound , sensitivity to smells , fatigue, and irritability. Many thus seek a dark and quiet room. In a basilar migraine , a migraine with neurological symptoms related to the brain stem or with neurological symptoms on both sides of

2765-413: Is with over-the-counter analgesics (pain medication) such as ibuprofen and paracetamol (acetaminophen) for headache, antiemetics (anti-nausea medication) for nausea, and the avoidance of migraine triggers. Specific medications such as triptans , ergotamines , or calcitonin gene-related peptide receptor antagonist (CGRP) inhibitors may be used in those experiencing headaches that do not respond to

2844-434: The brainstem and diencephalon ), while other data support the role of peripheral activation (such as via the sensory nerves that surround blood vessels of the head and neck). The potential candidate vessels include dural arteries , pial arteries and extracranial arteries such as those of the scalp . The role of vasodilatation of the extracranial arteries, in particular, is believed to be significant. Adenosine ,

2923-491: The exocytosis complex. Another genetic disorder associated with migraine is CADASIL syndrome or cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy. One meta-analysis found a protective effect from angiotensin converting enzyme polymorphisms on migraine. The TRPM8 gene, which codes for a cation channel , has been linked to migraine. The common forms migraine are Polygenetic , where common variants of numerous genes contributes to

3002-610: The limbic system and hypothalamus as the origin of prodromal symptoms in migraine. Aura is a transient focal neurological phenomenon that occurs before or during the headache. Aura appears gradually over a number of minutes (usually occurring over 5–60 minutes) and generally lasts less than 60 minutes. Symptoms can be visual, sensory or motoric in nature, and many people experience more than one. Visual effects occur most frequently: they occur in up to 99% of cases and in more than 50% of cases are not accompanied by sensory or motor effects. If any symptom remains after 60 minutes,

3081-474: The over-the-counter drug Migraleve (paracetamol and codeine for analgesia, with buclizine as the antiemetic). The role for these products is between just the use of simple analgesics (paracetamol or ibuprofen) and the triptan class of drugs; although the latter are not options during pregnancy. In the elderly although triptans are generally avoided, so too are antiemetics such as metoclopramide due to higher risks of side effects. In Australia and New Zealand,

3160-552: The serotonin syndrome . Pharmacokinetic interactions (for example, mediated by CYP liver enzymes or transporter proteins ) are different for the individual substances; for most triptans, they are mild to absent. Eletriptan blood plasma levels are increased by strong inhibitors of CYP3A4 , and frovatriptan levels by CYP1A2 inhibitors such as fluvoxamine . Their action is attributed to their agonist effects on serotonin 5-HT 1B and 5-HT 1D receptors in blood vessels (causing their constriction ) and nerve endings in

3239-637: The 5-HT 1D/B receptors. These drugs have been available only by prescription (US, Canada and UK), but sumatriptan became available over-the-counter in the UK in June 2006. The brand name of the OTC product in the UK is Imigran Recovery. The patent on Imitrex STATDose expired in December 2006, and injectable sumatriptan became available as a generic formula in August 2008. Sumavel Dosepro

3318-461: The 5-HT receptor to discover a more direct 5-HT agonist with fewer side effects. They continued developing and working on a desirable action on 5-HT by 5-HT 1 receptor activation for an anti-migraine drug. Continued work led to the development of sumatriptan, now known as the first 5-HT 1 agonist, selective for the 5-HT 1D/B receptors and also the 5-HT 1F receptor with less affinity. By 1991 sumatriptan became available in clinical use in

3397-477: The Netherlands and in the US in 1993. However, there was always a debate about its mechanism of action, and it still remains unclear today. Later, Mike Moskowitz proposed a theory about "neuronal extravasation", and this was the first clue that sumatriptan might have a direct neuronal effect in migraine attacks. Sumatriptan became a prototype for other triptans that have been developed for improved selectivity for

3476-559: The accumulated genetic risk of the common variations, into a so-called polygenetic risk , it is possible to assess e.g. the treatment response to triptans. Migraine may be induced by triggers, with some reporting it as an influence in a minority of cases and others the majority. Many things such as fatigue, certain foods, alcohol, and weather have been labeled as triggers; however, the strength and significance of these relationships are uncertain. Most people with migraine report experiencing triggers. Symptoms may start up to 24 hours after

3555-493: The acute headache has settled. Many report a sore feeling in the area where the migraine was, and some report impaired thinking for a few days after the headache has passed. The person may feel tired or "hung over" and have head pain, cognitive difficulties, gastrointestinal symptoms, mood changes, and weakness. According to one summary, "Some people feel unusually refreshed or euphoric after an attack, whereas others note depression and malaise ." The underlying cause of migraine

3634-709: The aura phase and dilated during the pain phase, so a constrictive medication like a triptan is not recommended during the aura. Triptans are effective for the treatment of cluster headache . This has been demonstrated for subcutaneous sumatriptan and intranasal zolmitriptan, the former of which is more effective according to a 2013 Cochrane review . Tablets were not considered appropriate in this review. A single randomized controlled trial found that sumatriptan may be able to prevent altitude sickness . All marketed triptans are available in oral form; some in form of sublingual tablets. Sumatriptan and zolmitriptan are also available as nasal sprays . For sumatriptan,

3713-408: The body, common effects include a sense of the world spinning , light-headedness, and confusion. Nausea occurs in almost 90% of people, and vomiting occurs in about one-third. Other symptoms may include blurred vision , nasal stuffiness, diarrhea, frequent urination, pallor , or sweating. Swelling or tenderness of the scalp may occur as can neck stiffness. Associated symptoms are less common in

3792-648: The brain but they differ in quantity at each area. An important initiator of head pain is suggested to be the activation of trigeminovascular afferent nerves which upon activation releases neuropeptides such as CGRP, substance P and neurokinin A . Also they are thought to promote neurogenic inflammatory response important for sensitization of sensory afferents, and also transmission and generation of head pain centrally. 5-HT 1D has been found responsible for inhibition of neurogenic inflammation upon administration with sumatriptan and other related compounds that act on prejunctional 5-HT 1D receptors. All triptans, like

3871-401: The brain, and sodium dependent cell metabolic activity. Triptans have a wide variety of pharmacokinetic properties. Bioavailability is between 14% and 70%, biological half-life (T 1/2 ) is between 2 and 26 hours. Their good ability to cross the blood–brain barrier and the rather long half life of some triptans may result in lower frequencies of migraine recurrence. Zolmitriptan

3950-428: The brain, and subsequent inhibition of pro-inflammatory neuropeptide release, including CGRP and substance P . Triptans are selective agents for 5-HT 1B and 5-HT 1D and have low or even no affinity for other types of 5-HT receptors. 5-HT receptors are classified into seven different families named 5-HT 1 to 5-HT 7 . All receptors are G protein coupled receptors with seven transmembrane domains with

4029-636: The brain. The first clinically available triptan was sumatriptan , which has been marketed since 1991. Triptans have largely replaced ergotamines , an older class of medications used to relieve migraine and cluster headaches. Triptans are used for the treatment of severe migraine attacks or those that do not respond to NSAIDs or other over-the-counter drugs. Triptans are a mid-line treatment suitable for many migraineurs with typical attacks. They may not work for atypical or unusually severe migraine attacks, transformed migraine, or status migrainosus (continuous migraine). Triptans are highly effective, reducing

4108-453: The cell. After the burst of activity, the blood flow to the cerebral cortex in the area affected is decreased for two to six hours. It is believed that when depolarization travels down the underside of the brain, nerves that sense pain in the head and neck are triggered. The exact mechanism of the head pain which occurs during a migraine episode is unknown. Some evidence supports a primary role for central nervous system structures (such as

Migraine Migraine ( UK : / ˈ m iː ɡ r eɪ n / , US : / ˈ m aɪ -/ ) is a genetically-influenced complex neurological disorder characterized by episodes of moderate-to-severe headache , most often unilateral and generally associated with nausea and light and sound sensitivity . Other characterizing symptoms may include vomiting , cognitive dysfunction , allodynia , and dizziness . Exacerbation or worsening of headache symptoms during physical activity

4266-483: The contrary, the FDA and some other drug governance bodies have stated that monoamine oxidase inhibitors are contraindicated for sumatriptan, zolmitriptan and rizatriptan, and combination with ergot alkaloids such as ergotamine for all substances. At least two triptans (sumatriptan and rizatriptan) have been listed under the unacceptable medication by the Canadian Blood Services as a potential risk to

4345-515: The early 1950s it was confirmed that both substances were the same. In the mid-1950s it was proposed that serotonin had a role as a neurotransmitter in the central nervous system (CNS) of animals. Investigations of the mechanism of action were not very successful as experimental techniques were lacking. Later in the 1960s, studies showed that vasoconstriction caused by 5-HT, noradrenaline and ergotamine could reduce migraine attacks. Patrick P.A. Humphrey among others at Glaxo started researching

4424-677: The elderly. Sometimes, aura occurs without a subsequent headache. This is known in modern classification as a typical aura without headache , or acephalgic migraine in previous classification, or commonly as a silent migraine. However, silent migraine can still produce debilitating symptoms, with visual disturbance, vision loss in half of both eyes, alterations in color perception, and other sensory problems, like sensitivity to light, sound, and odors. It can last from 15 to 30 minutes, usually no longer than 60 minutes, and it can recur or appear as an isolated event. The migraine postdrome could be defined as that constellation of symptoms occurring once

4503-611: The first medication ( Erenumab ) of a new class of drugs specifically designed for migraine prevention called calcitonin gene-related peptide receptor antagonists (CGRPs) was approved by the FDA . As of July 2023, the FDA has approved eight drugs that act on the CGRP system for use in the treatment of migraine. Globally, approximately 15% of people are affected by migraine. In the Global Burden of Disease Study , conducted in 2010, migraine ranked as

In 200 BCE, writings from the Hippocratic school of medicine described the visual aura that can precede the headache and a partial relief occurring through vomiting. Triptan Triptans are a family of tryptamine -based drugs used as abortive medication in the treatment of migraines and cluster headaches . This drug class

4661-443: The headache is unilateral, throbbing, and moderate to severe in intensity. It usually comes on gradually and is aggravated by physical activity during a migraine attack. However, the effects of physical activity on migraine are complex, and some researchers have concluded that, while exercise can trigger migraine attacks, regular exercise may have a prophylactic effect and decrease frequency of attacks. The feeling of pulsating pain

4740-403: The most used triptans for migraines in children. Triptans should be taken as soon as possible after the onset of pain. In case of migraine with aura they are to be taken after the aura and with the onset of pain. If taken too early, they may not have the full effect on symptom reduction, and in case of an aura, they can worsen the aura. It is assumed that blood vessels are constricted during

4819-524: The neurotransmitter serotonin , also known as 5-hydroxytryptamine (5-HT), are also believed to be involved. Calcitonin gene-related peptides (CGRPs) have been found to play a role in the pathogenesis of the pain associated with migraine, as levels of it become elevated during an attack. The diagnosis of a migraine is based on signs and symptoms. Neuroimaging tests are not necessary to diagnose migraine, but may be used to find other causes of headaches in those whose examination and history do not confirm

Comparison of sumatriptan and dihydroergotamine showed that dihydroergotamine has high affinity and sumatriptan has medium affinity for 5-HT 1D . Triptans have at least three modes of action. These antimigraine mechanisms are: Other possibilities of triptans in antimigraine effects are modulation of nitric oxide dependent signal transduction pathways , nitric oxide scavenging in

Each family couples to the same second messenger systems . Subtypes of 5-HT 1 are the 5-HT 1A , 5-HT 1B , 5-HT 1D , 5-HT 1E and 5-HT 1F receptors. All 5-HT 1D receptors are coupled to inhibition of adenylate cyclase . 5-HT 1B and 5-HT 1D receptors have been difficult to distinguish on

5056-783: The over-the-counter pain medications. For people who experience four or more attacks per month, or could otherwise benefit from prevention, prophylactic medication is recommended. Commonly prescribed prophylactic medications include beta blockers like propranolol , anticonvulsants like sodium valproate , antidepressants like amitriptyline , and other off-label classes of medications. Preventive medications inhibit migraine pathophysiology through various mechanisms, such as blocking calcium and sodium channels , blocking gap junctions , and inhibiting matrix metalloproteinases , among other mechanisms. Non-pharmacological preventive therapies include nutritional supplementation, dietary interventions, sleep improvement, and aerobic exercise. In 2018,

5135-679: The pain, duration of the headache, and frequency of attacks are variable. A migraine attack lasting longer than 72 hours is termed status migrainosus. There are four possible phases to a migraine attack, although not all the phases are necessarily experienced: Migraine is associated with major depression , bipolar disorder , anxiety disorders , and obsessive–compulsive disorder . These psychiatric disorders are approximately 2–5 times more common in people without aura, and 3–10 times more common in people with aura. Prodromal or premonitory symptoms occur in about 60% of those with migraine, with an onset that can range from two hours to two days before

5214-423: The paracetamol has been shown to enhance the analgesia relief when used to treat the pain of arthritis . Whilst the individual component drugs may be prescribed individually, as a combination, it is only available as the branded Paramax preparation in the UK. In the UK there are only two other combination analgesics with antiemetics (i.e., anti-nausea) products available: MigraMax ( aspirin with metoclopramide) and

An early description consistent with migraine is contained in the Ebers Papyrus , written around 1500 BCE in ancient Egypt. The word migraine is from the Greek ἡμικρᾱνίᾱ ( hēmikrāníā ), 'pain in half of

5372-459: The predisposition for migraine. These genes can be placed in three categories increasing the risk of migraine in general, specifically migraine with aura, or migraine without aura. Three of these genes, CALCA , CALCB , and HTR1F are already target for migraine specific treatments. Five genes are specific risk to migraine with aura, PALMD , ABO , LRRK2 , CACNA1A and PRRT2 , and 13 genes are specific to migraine without aura. Using

The most common adverse effect is recurrence of migraine. A systematic review found that "rizatriptan 10 mg was the only triptan with a recurrence rate greater than that of placebo". There is a theoretical risk of coronary spasm in patients with established heart disease, and cardiac events after taking triptans may rarely occur. Combination of triptans with other serotonergic drugs such as ergot alkaloids, monoamine oxidase inhibitors, selective serotonin reuptake inhibitors (SSRIs), serotonin–norepinephrine reuptake inhibitors (SNRIs) or St John's wort has been alleged to induce symptoms of

5530-483: The risk by a small to moderate amount. Single gene disorders that result in migraine are rare. One of these is known as familial hemiplegic migraine , a type of migraine with aura, which is inherited in an autosomal dominant fashion. Four genes have been shown to be involved in familial hemiplegic migraine. Three of these genes are involved in ion transport . The fourth is the axonal protein PRRT2 , associated with

People with migraine, particularly women, may develop higher than average numbers of white matter brain lesions of unclear significance. Migraine is common, with around 33% of women and 18% of men affected at some point in their lifetime. Onset can be at any age, but prevalence rises sharply around puberty , and remains high until declining after age 50. Before puberty, boys and girls are equally impacted, with around 5% of children experiencing migraine attacks. From puberty onwards, women experience migraine attacks at greater rates than men. From age 30 to 50, up to 4 times as many women experience migraine attacks as men., this

5688-445: The same side. Numbness usually occurs after the tingling has passed with a loss of position sense . Other symptoms of the aura phase can include speech or language disturbances, world spinning , and less commonly motor problems. Motor symptoms indicate that this is a hemiplegic migraine , and weakness often lasts longer than one hour unlike other auras. Auditory hallucinations or delusions have also been described. Classically

5767-404: The start of pain or the aura. These symptoms may include a wide variety of phenomena, including altered mood, irritability, depression or euphoria , fatigue , craving for certain food(s), stiff muscles (especially in the neck), constipation or diarrhea , and sensitivity to smells or noise. This may occur in those with either migraine with aura or migraine without aura. Neuroimaging indicates

5846-411: The state is known as persistent aura . Visual disturbances often consist of a scintillating scotoma (an area of partial alteration in the field of vision which flickers and may interfere with a person's ability to read or drive). These typically start near the center of vision and then spread out to the sides with zigzagging lines which have been described as looking like fortifications or walls of

5925-506: The surgical migraine treatment by decompression of extracranial sensory nerves adjacent to vessels suggests that people with migraine may have anatomical predisposition for neurovascular compression that may be caused by both intracranial and extracranial vasodilation due to migraine triggers. This, along with the existence of numerous cranial neural interconnections, may explain the multiple cranial nerve involvement and consequent diversity of migraine symptoms. Studies of twins indicate

6004-441: The symptoms or aborting the attack within 30 to 90 minutes in 70–80% of patients. A test measuring a person's skin sensitivity during a migraine may indicate whether the individual will respond to treatment with triptans. Triptans are most effective in those with no skin sensitivity; with skin sensitivity, it is best to take triptans within twenty minutes of the headache's onset. Oral rizatriptan and nasal zolmitriptan are

6083-450: The third-most prevalent disorder in the world. It most often starts at puberty and is worst during middle age. As of 2016 , it is one of the most common causes of disability . Migraine typically presents with self-limited, recurrent severe headache associated with autonomic symptoms. About 15–30% of people living with migraine experience episodes with aura , and they also frequently experience episodes without aura. The severity of

6162-476: Was first commercially introduced in the 1990s. While effective at treating individual headaches, they do not provide preventive treatment and are not considered a cure . They are not effective for the treatment of tension–type headache , except in persons who also experience migraines. Triptans do not relieve other kinds of pain . The drugs of this class act as agonists for serotonin 5-HT 1B and 5-HT 1D receptors at blood vessels and nerve endings in

6241-405: Was published in 2018. According to this classification, migraine is a primary headache disorder along with tension-type headaches and cluster headaches , among others. Migraine is divided into six subclasses (some of which include further subdivisions): The diagnosis of abdominal migraine is controversial. Some evidence indicates that recurrent episodes of abdominal pain in the absence of
