Feedback BAM and Migraine Variants Though BAM is a migraine variant, and therefore technically belongs under the classification of "migraine," a BAM attack can also represent a form of "acute cerebral vascular insufficiency." The other forms of migraine variant are (1) retinal migraine, (2) opthalmoplegic migraine, (3) hemiplegic migraine, (4) facial migraine, and (5) migrainous infarction. Of these, only hemiplegic migraine has been found to be a dominant characteristic in terms of heritability in families. Hemiplegic migraine is also the only form of migraine for which a gene has been located. It is a gene located on chromosome 19 that carries the trait for hemiplegic migraine. Hemiplegia can develop either before or during a migraine. Though Basilar Artery Migraine is certainly a distinct form of migraine variant, BAM patients can exhibit the signs of hemiplegic migraine. The last category of migraine variants listed above, that of migrainous infarction, deserves special note when discussing BAM.
Extractions: Home About New Bookstore ... Feedback The Physiology of BAM The physiology of Basilar Artery Migraine is somewhat unique, and the condition is often difficult to diagnose. Basilar Artery Migraines are a complicated phenomenon involving biochemical, neurogenic, and vascular components. Persons with Basilar Artery Migraine can exhibit symptoms also found in other neurological disorders such as stroke or epilepsy. Patients' reports of Basilar Artery Migraine symptoms, especially in severe cases, can prompt the often arduous process of differential diagnosis to rule out conditions like epilepsy, stroke (cerebral infarct), brain tumor, aneurysm, or other neurological conditions. The Direct Causes of BAM BAM is a result of vasospasm (spasm of the artery or vessel) or vasoconstriction (constriction or narrowing of the artery or vessel) in the area of the vertebrobasilar circulation, most likely usually in the basilar artery itself. Spasm or constriction in the basilar artery necessarily affects the circulation of blood in the entire vertebrobasilar region, as the basilar artery itself is key to providing circulation to the posterior areas of the brain. BAM is a migraine variant that involves ischemia (lack of sufficient blood supply) to parts of the brain supplied by the vertebrobasilar circulatory system.

Whats New In Research 1 A ground breaking discovery the cause of one of the migraines. The cause ofone form of migraine, familial hemiplegic migraine, has been discovered. http://www.migrainetrust.org/research/resrch1.htm
Extractions: - the cause of one of the migraines The cause of one form of migraine, familial hemiplegic migraine, has been discovered. It has been found to be a defective gene which encodes for a calcium channel and has been isolated by a group in Holland led by Professor Rene Frants and Dr Michel Ferrari. Professor Peter Goadsby (Headache Group, Institute of Neurology, Queen Square, London UK), a neurologist who is both a Trustee of the Migraine Trust, and is also collaborating on the project, explains the impact of this discovery for both sufferers and researchers. Familial Hemiplegic Migraine (FHM) is a rare form of migraine, inherited through autosomal dominance, which means that half of the children of an affected parent will get the disorder. As FHM is a form of migraine, it manifests itself as headache, with all the typical things that you might see in migraine; nausea, sensitivity to light, sensitivity to sound, sensitivity to movement. However, the aura part of hemiplegic migraine, instead of being flashing lights or spots in the vision or pins and needles down one side of the body, is a hemiplegia or paralysis down on one side of the body, so the arm and the leg do not work properly, and in many cases become completely paralysed.

Migraine Chapter, Prolonged Aura , B.Todd Troost yet provided useful information on the pathophysiology of complicated migraine.{7476}hemiplegic migraine occurs both sporadically and as a familial syndrome. http://imigraine.net/migraine/prolonged.html
Extractions: Focal symptoms and signs of the aura may persist beyond a headache phase. In the previous classification, this was termed complicated migraine. It is now defined by the IHS classification with two labels with increased specificity. If the aura lasts for longer than one hour but less than one week, the term migraine with prolonged aura is applied. If the signs persist for more than one week or a neuroimaging procedure demonstrates a stroke, a migrainous infarction has occurred. As pointed out previously, mid or later life the aura may not be followed by headache and has been termed migraine accompagnée or migraine associée . Migraine with aura (classic) in early reports was sometimes referred to as "ophthalmic migraine" (to be differentiated from ophthalmoplegic migraine, a subtype of migraine with aura). Migraine with aura is further reviewed under the headings: Cerebral, Ophthalmoplegic, Retinal, Basilar, and Other Varieties. A variety of cerebral symptoms may occur in migraine with aura, including motor, visual, and other sensory defects. As pointed out previously, if the aura lasts for more than one hour , but less than one week, the term migraine with prolonged aura is applied. However, if the signs persist for more than one week, or a neuroimaging procedure shows a stroke the term used is

Untitled To be termed a familial hemiplegic migraine, the sufferer must have symptoms ofhemiparesis or a pins and needles feeling on one side or limb of the body. http://www.msu.edu/user/espino11/familia.htm
Extractions: Familial hemiplegic migraines Familial hemiplegic migraines are associated with severe headache pain and a gradual onset of unilateral weakness or heaviness. To be termed a familial hemiplegic migraine, the sufferer must have symptoms of hemiparesis or a pins and needles feeling on one side or limb of the body. This type of migraine could completely resolve in minutes or last several hours, but the hemiparises will last hours or days beyond the headache itself. It is also very typical that the hemiparesis may being evfen before the headache attack. A complicated hemiplegic attack also occurs, where the weakness may last up to two weeks or may never resolve entirely. A familial hemiplegic migraine is ususally inherited from the mother and the affected side of the body in most instances is associated with dysphasia and other cortical symtoms. Becuase of ischaemic changes in the cerebrum and brainstem, deaths due to familial hemiplegic migraines have been recorded. Back to Main Page

Extractions: The Migraine Gene Overview The familial hemiplegic migraine, FHM, a subtype of migraine with aura, has been mapped to chromosome 19p13. Brain-secifif P/Q-type calcium-channel alpha -subunit gene, CACNA1A is identified in the responsible region of 47 exons covering 300 kb. The familial hemiplegic migraine is the result of a missense mutation in the alpha subunit. In the sequencing of all the exons and their corresponding surroundings, a polymorphic variation is revealed, including a (CA) n -repeat and a (CAG) n -repeat in the 3' untranslated region. In the familial hemiplegic migraine, four missense mutations were discovered in conserved functional domains and one of the mutations has occurred in two different unrelated families of hemiplegic migraines. FHM is a rare autosomal dominant subtype migraine with aura and is associated within some families with progressive cerebellar atrophy and ictal hemiparesis. The cerebellar atrophy was found in FHM is linked to the chromosome 19p13. The region that contains chromosome 19p13 FHM locus is also involved with migraines with or without auras. This adds to the hypothesis that FHM is part of the migraine spectrum involving biological mechanisms and similar genetic factors. Mutations In FHM, several synonymous nucleotide substitutions and polymorphisms were identified by their occurrence in lack of cosegregation with the disease and in unaffected controls. The

WHAT CAUSES MIGRAINE HEADACHES? Researchers have located a single genetic mutation responsible for the very rarefamilial hemiplegic migraine, but a number of genes are likely to be involved http://www.ucdmc.ucdavis.edu/ucdhs/health/a-z/97migraine/doc97causes.html
Extractions: Until recently, the general theory on the migraine process rested solely on the idea that abnormalities of blood vessel (vascular) systems in the head were responsible for migraines. Now, however, experts tend to believe that migraine starts with an underlying central nervous system disorder, which, when triggered by various stimuli, sets off a chain of neurologic and biochemical events, some of which subsequently affect the brain's vascular system. No experimental model fully explains the migraine process. There is certainly a strong genetic component in migraine with or without auras. Researchers have located a single genetic mutation responsible for the very rare familial hemiplegic migraine, but a number of genes are likely to be involved in the great majority of migraine cases. A number of chemicals, structures, nerve pathways, and other players involved in the process are under investigation. Central Nervous Disorder.
