In order to discuss Hemiplegic Migraine, we have to understand that Migraine attacks are episodic manifestations of a genetic neurological disease. Migraine can present in a variety of ways. Hemiplegic Migraine is a rare form of Migraine, made more confusing by there being two variations: Familial Hemiplegic Migraine (FHM) and Sporadic Hemiplegic Migraine (SHM). Both FHM and SHM often begin in childhood and cease during adult years. Diagnosing FHM and SHM can be difficult as the symptoms are also indicative of vascular disease. and can be thought to be stroke, epilepsy, or other conditions. A full neurological work up and careful review of medical history and symptoms are necessary to rule out other causes and confirm a diagnosis of FHM or SHM. Family medical history is especially helpful in diagnosing FHM. FHM and SHM share the same symptoms, which will vary among different Migraineurs. The difference between the two is that FHM can be traced back in the family history and has been linked to mutations of specific genes on chromosomes 1 and 19. SHM is FHM without the familial connection and that particular genetic mutation.

Extractions: The authors describe 4 patients with sporadic hemiplegic migraine (SHM) who were responsive only to oral or intravenous verapamil not to other common migraine therapies. The authors had previously reported a successful response to intravenous verapamil in familial hemiplegic migraine (FHM); this study confirms the efficacy of this agent. If new genetic studies have revealed de novo mutation of CACN1A1 in patients with SHM, then it may be part of the spectrum of FHM syndrome. Neuronal calcium channel dysfunction may underlie the pathogenesis of both forms of hemiplegic migraine; the calcium-channel blocker verapamil is an effective treatment for both disorders.

Genes And Migraine hemiplegic migraine The inherited or familial form of hemiplegic migraine isa rare In these families, hemiplegic migraine has an autosomal dominant http://www.headachedrugs.com/archives/genes_migraine.html
Extractions: Many migraineurs have other family members who also suffer with migraine headache. Mom used to have migraine headaches with her menstrual cycle, grandmother once had "sick" headaches, and brother has "sinus" headaches which are less severe but sound strangely similar to migraine if you ask questions about symptoms and triggers. For years scientists have argued whether disorders such as migraine that tend to run in families do so because of shared genes or the shared environment. People often assume that any disorder that occurs in several family members must be genetic. However, families tend to share similar diets, exposures and lifestyles, all of which might be involved in making someone susceptible to a specific disorder. A combination of genetic and environmental factors seems to be the best overall explanation for most common disorders, including migraine. Nevertheless, the fact that you occasionally find large families with many members suffering from migraine suggest a stronger genetic basis for those particular families. As it turns out, a definite inheritance pattern has been found in a few families who suffer with a severe form of migraine called hemiplegic migraine.
Extractions: Abstract Recent reports suggest that Botulinum toxin type A may help patients suffering from chronic pain disorders. We report a unique case of a 47 year old woman with hemiplegic migraine responding to botulinum toxin type A injections. There is increasing evidence that botulinum toxin type A may be a useful treatment for severe headaches and migraines. To our knowledge this is the first case report of its successful use in sporadic hemiplegic migraine. Case report A 44 year old woman was referred to a tertiary neuropsychiatric centre by her GP with disabling headaches. At the age of 41 she developed episodes of severe headache for the first time which gradually increased in severity. There was no family history of migraine. Episodes would start with nausea for 30 to 60 minutes followed by a pain in her forehead which could be right or left sided and occasionally bilateral and which spread gradually to the back of her head and down her neck. She also had mild photophobia, phonophobia and prostration. She often would notice "a cloudy film" over her vision but no classic migrainous visual disturbances. She described headaches as "horrendous" like "a tightening band" around her head. They occurred at any time of the day but often were present when she awakened. Simple analgesics were largely ineffective in reducing the pain.

Extractions: Timothy C. Hain, MD Please read our Return to Index Search this site Page last modified: November 1, 2004 This disorder is an autosomal domininant condition characterized by migraine, hemiparesis, and in some families, progressive cerebellar atrophy. FHM1 is associated with a mutation in the a-1 a subunit gene for calcium channels. Four different missence mutations have been identified. Mutations in this subunit have also been identified in one of the episodic ataxias , and in one of the spinocerebellar atrophies (SCA-6). FHM2 is associated with a mutaiton in the ATPase gene. It has recently been suggested that both of these mutations render the brain more susceptible to glutamate release (Moskowitz et al, 2004). FHM1 and FHM2 are characterized by enhanced susceptibility and sustained attacks of visual, somatosensory and aphasic auras as well as by prolonged motor weakness or paralysis. Photophobia, phonophobia, nausea and vomiting are also common symptoms. Motor weakness is uncommon in classic migraine (migraine with aura). Moskowitz and others.

This MRI shows prominent atrophy (shrinkage) of the midline (called the vermis). The main goal of this page is to serve as a repository for recent information about inherited cerebellar degenerations. It is not comprehensive, but we hope that it might be of some use to individuals searching for information about these rare conditions on the web. We highly recommend also using the OMIM database , which can be accessed on the web. A large number of the genetic ataxias can be tested for using contemporary methodology. An example of a lab that does this is Athena Most of the information here concerns inherited conditions, as there is considerable new data derived from researchers using a nearly complete map of the human genome (your tax dollar is doing some good !), and improvements in the technology of molecular biology. It seems quite feasible that within the next decade, we may be able to determine the gene that is damaged in most inherited cerebellar degenerations. As these data become known, it may also be possible to target specific therapies, probably over the next 2 decades. In other words, stay tuned, but we aren't there yet. There are numerous non-genetic causes of cerebellar disease.

Extractions: unregistered posted 11-05-2002 08:31 PM Dear Colleagues: We are currently looking for genes involved in familial hemiplegic migraine (FHM). We are interested in forming collaborations with clinicians/researchers with access to large Mendelian families with FHM. We would prefer to study families with greater than ten affecteds but families with six or more affecteds will be considered. We look forward to hearing from you. Please respond directly to:
