Baylor Neurology Case Of The Month presentation suggested a TIA, embolic stroke, or complex partial seizure with apostictal paralysis (though one might also consider a hemiplegic migraine). http://www.bcm.tmc.edu/neurol/challeng/pat27/summary.html
Extractions: Diagnosis: Ischemic stroke secondary to postinfectious focal varicella vasculitis Patient #27 presented with the sudden onset of transient inability to talk accompanied by left-sided weakness. These episodes lasted only 30 to 60 seconds and subsequently resolved (with the exception of the last episode, which left a sustained deficit). The distribution of involvement (face, arm and leg) suggests a subcortical process, though the inability to talk suggests cortical involvement. However, the finding of left-sided weakness associated with a true aphasia would be very unusual unless the person in question was left-handed and the lesion/process involved subcortical as well as cortical structures (in other words, a large stroke). Speech arrest can be seen with sudden neurological deficits in several areas including non-dominant subcortical regions, but the speech arrest is usually transient as in this case. The child's initial clinical presentation suggested a TIA, embolic stroke, or complex partial seizure with a post-ictal paralysis (though one might also consider a hemiplegic migraine). Stroke in the young is often the result of an underlying metabolic abnormality or overwhelming intercurrent illness. Focal seizures may result from structural abnormalities, stroke, or a parasitic infection such as neurocysticercosis, among others. As the child's illness progressed, and results of the laboratory studies and radiographic images became available, the differential diagnosis was narrowed.
Extractions: Durham, NC Aims and Scope Voltage-gated calcium channels control numerous critical cellular functions in neuronal and non-neuronal cells. They are targets of numerous therapeutic agents, ethyl alcohol, arthropod and mollusk toxins and some environmentally relevant toxic metals. Certain rare diseases including Lambert-Eaton Myasthenic Syndrome (LEMS), hereditary ataxias and Familial Hemiplegic Migraine may also be the result of altered calcium channel function. Therefore, it is important to define and identify what is currently known about voltage-gated calcium channels, the role they play in certain rare disorders, and the role that xenobiotics play in their dysfunction. This workshop will bring together neurobiologists, neurotoxicologists and neurologists to explore the state of the science/medicine in this field with the ultimate goal of identifying research gaps, both basic and clinical.

Extractions: MIGRAINE WITH PROLONGED AURA AND MIGRAINOUS INFARCTIONS In the new classification of migraine, Subtype 1.6 indicates complications of migraine. This would include all of the permanent defects discussed in this section. 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 or . 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. Cerebral 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

Extractions: LATEST NEWS Headaches in Parliament Phil Hope, MP for Corby, Northants, last week drew the attention of parliament to the plight of severe headache sufferers in a debate on the National Service Framework for Long Term Medical Conditions with a particular focus on neurological conditions. Mr Hope expressed concern that although primary headache disorders, including migraine, are the most common neurological conditions in the UK there has, as yet, been no confirmation that they will be included in this NSF. He emphasised that migraine is very different and much more debilitating than an ordinary headache and can have a substantial impact on the quality of life of sufferers. Despite its prevalence, affecting 15% of people in the UK, the physical, emotional, social and economic burdens are poorly acknowledged. He called for better education and a reallocation of resources to ensure improved care for sufferers at primary care level. Failure to deliver this can result in sufferers developing other medical conditions such as depression and referrals to already over stretched hospital neurology departments. For the government, Mr David Lamey , Parliamentary Under-Secretary of State for Health, confirmed that this NSF will focus on working age adults, will address issues common to all neurological conditions and that conditions such as headache will be considered. This NSF is scheduled for publication in 2004 with a 10 year implementation programme commencing in 2005.

Extractions: sini Migrain Migrain juga dikenali sebagai hemikrania, perkataan Greek yang membawa maksud sebelah tengkorak. Ia juga dikenali sebagai vascular headache. Sakit kepala yang berlaku berulang, berdenyut-denyut selalunya terjadi sebelah kepala sahaja. Ada juga yang bermula di sebelah kepala sahaja dan kemudiannya melarat kedua-dua belah kepala. Dalam kes yang teruk, migrain menyebabkan pening (nausea), muntah, cirit-birit, pengekalan cecair badan (retention of fluid) dan sensitif kepada bunyi dan cahaya. Jenis-jenis migrain yang utama. 1 - Classic migraine Lebih kurang 10% hingga 15% pesakit migrain mengalami migrain jenis ini. 10 hingga 30 minit sebelum berlakunya migrain, tanda-tanda awal (warning) berlaku. Tanda-tanda ini dikenali sebagai aura atau prodrome dan ia berlaku selama 5 - 15 minit. Tanda-tanda aura ini adalah seperti berikut: terlihat cahaya terang (bright spots), garisan zigzag (zigzag lines), penglihatan berganda (double vision), buta sementara (temporary blindness), kebas (numbness), kepala terasa berpusing (dizziness), pening (drowsiness), sukar bercakap (slurred speech) dan keliru (confusion). Selepas tanda-tanda ini hilang, migrain mula menyerang. Aura dikatakan disebabkan oleh saluran darah yang menghantar darah ke otak dan tisu sekelilingnya mengecil sementara, jadi menghad penghantaran darah ke bahagian tersebut. Ini menyebabkan gangguan pada saraf rasa dan pengawalan motor. Bagaimanapun ada juga yang mengatakan bahawa aura bermula di sistem saraf satu fenomena yang dikenali sebagai spreading depression of the cortex. Ada kajian yang menunjukkan bahawa pengaliran darah hanya bertambah beberapa jam selepas aura terjadi dan sakit kepala bermula.

Extractions: Edition Sponsored by the U.S. Department of Energy Human Genome Program Human Genome News, October-December 1996; 8(2) Migraine Two research groups report results suggesting a common genetic cause for migraine and epilepsy and the availability of an animal model that may be useful for further studies. Both groups used the chromosome 19 physical map and selected clones supplied by the Human Genome Center at Lawrence Livermore National Laboratory (LLNL). Researchers led by Lisa Stubbs at Oak Ridge National Laboratory (ORNL) reported the isolation, mapping, and expression analysis of the chromosome 8 gene found in the mutant "tottering" mice studied extensively as models for human epilepsy and cerebeller ataxia. The mouse region is homologous to a human chromosome 19 region previously implicated in episodic ataxia type 2 and familial hemiplegic migraine (an inherited form of migraine). Now the ORNL studies indicate that mutations in the human gene are indeed the causative factor in both disorders. Tottering mutants may thus represent mouse models of both diseases, according to the authors of the

Extractions: Edition Sponsored by the U.S. Department of Energy Human Genome Program Human Genome News, January 1998; 9:(1-2) Most current tests for human exposure to environmental mutagens are only indicators of genetic damage and cannot predict adverse outcomes for individuals. In the following article, Anthony V. Carrano [Lawrence Livermore National Laboratory (LLNL)] explains that the future of genetic toxicology and mutation research lies in studying genes and individual genetic variation to reveal risk factors that make some people more susceptible to disease. The basic topic addressed by scientists who explore these issues, he notes, is the nature and consequence of genetic change or variation, with the ultimate purpose of predicting or preventing disease. This article is excerpted from a talk by Carrano at the Human Genome Project session at the 1997 Society of Toxicology meeting in Cincinnati, Ohio. Other speakers were J. Craig Venter (The Institute for Genomic Research), Henry Wagner (Johns Hopkins University), and Richard Woychik (now at Case Western Reserve University). The first 6 years of the Human Genome Project are behind us, and now resources can be applied to functional genomic studies, the genomics of the future. Functional genomics will be facilitated by completing the entire human genome sequence as soon as possible and, along the way, sequencing a significant portion of the mouse and other model-organism genomes. We want to determine all transcript structures and gene-expression patterns in the human genome; ultimately, we want to understand the phenotypes resulting from mutations in every one of the open reading frames. Many groups have begun working in this area even before the genome project is completed, and much work reported at recent genome meetings is pointed toward functional genomics.
Extractions: How do I know if I have... A Migraine Headache Tension-type Headaches Cluster Headaches Sinus Headaches A Brain Tumor Although it is not uncommon for children to suffer from headaches, all too often a child's headache complaints are dismissed by parents and pediatricians. This is especially true when an adult in the family also suffers from headache. In these situations there is a tendency to assume that the child is imitating a family member or is just seeking attention. In families where there are no headache sufferers, the child's headache is often attributed to school phobia, stress, or malingering. Migraine is quite common during the childhood years. More than 8 million children and adolescents suffer from migraine resulting in greater than one million lost school days each year. Childhood migraine differs from adult migraine in a number of ways: Prior to puberty boys get migraine as often as girls; after puberty girls suffer from migraine more frequently

Migrainerubriek - Hoofdbrekens En Kopzorgen Na lezing van het proefschrift The molecular basis of familial hemiplegic migrainevan de Leidse moleculair bioloog Roel A. Ophoff zou je geneigd zijn de vraag http://people.zeelandnet.nl/vdwindt/migraine/domino.htm
Extractions: Voorwaarde voor de uitscheiding van serotonine is de instroom van calcium in de hersencellen. Calcium-ionen gaan de hersencel binnen via een kanaal. Als dat kanaaltje door veranderingen van het gen defect is, kan migraine ontstaan, met name die met auraverschijnselen, d.w.z. met stoornissen in het zien en de spraak. De vraag is of bepaalde genen of veranderingen in bepaalde genen mee over-erven. Het antwoord is: ja. Bepaalde genen zijn erfelijk bij een bepaalde aandoening, in dit geval familiaire hemiplegische migraine. De kans dat een vader of moeder met migraine zonen of dochters krijgen die ook migraine krijgen, is duidelijk verhoogd. Maar erfelijkheid (dus aanleg) verklaart niet alles. Ook de omgeving speelt -voor ieder individu verschillend- een rol bij migraine. Denk maar aan voeding, overgevoeligheid voor licht en geluid, stress, enz. Ophoff concludeert dat de genetische component slechts gedeeltelijk bijdraagt aan de oorzaak van migraine. Nader onderzoek (o.a. bij transgene muizen bij wie met het gen is gemanipuleerd) moet helpen het mysterieuze domino-effect van migraine te ontrafelen. En misschien kunnen deze genetische mechanismen ook de oorzaken van andere aandoeningen verklaren. Ophoff: "Vervolgstudie heeft bovendien aangetoond dat dit gen ook een rol moet spelen in de etiologie* van de gewone vormen van migraine." (*etiologie = de leer der ziekte-oorzaken). Dick de Scally

Extractions: Return to Education Index Last update: Feb 20, 2000 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.
