Extractions: Migraine is a complex, heterogeneous, and disabling neurological disease of unknown origin that shows strong familial aggregation, affecting 18% of females and 6% of males in the general population. The International Headache Society distinguishes between two types of migraine: migraine without aura (MO) and migraine with aura (MA). MA headache attacks occur in up to 30% of patients with migraine and are preceded or accompanied by transient focal neurological symptoms (aura), i. e. reversible visual, sensory, motor and/or aphasic symptoms. The only nosologic entity genetically well characterised is familial hemiplegic migraine (FHM). For this rare kind of autosomal dominant MO migraine 3 loci have been identified: on 19p13, on 1q21-q23 and on 1q31. A recent study identified a locus on 4q24 in which a common form of MA segregates as autosomal dominant trait and significant evidence of linkage was also found in chromosome Xq. We present clinical and molecular data from a large four-generation Italian family in which, migraine without aura (MO) segregates as an autosomal dominant trait. After exclusion of the known loci for autosomal dominant familial hemiplegic migraine and migraine with aura, we performed a genomewide analysis using 428 fluorescent-labelled microsatellite markers. We obtained significant evidence of linkage between the MO phenotype and the marker D14S978 on chromosome 14q22.1 (maximum LOD score of 3.70, at

Extractions: The presence of fetal DNA in maternal plasma has been explored only recently and data about factors affecting its release and clearance into and from maternal circulation are scarce. Increased fetal DNA levels in maternal plasma were observed in pathological placental conditions associated with hypertension and preeclampsia. The presence of abnormal patterns of fetal DNA before the manifestation of clinical signs can signal the risk of developing these pathologies, allowing us to adopt preventive strategies.
Migraine Variants down. Complicated migraine is accompanied by a neurological deficit.Familial hemiplegic migraine is an example of this. Complicated http://www.neuro.nwu.edu/meded/headache/migraine_variants.htm
Extractions: Referal to our headache specialist (at Northwestern in Chicago, IL, USA): About 10% of the population has Migraine. There are many variants, of which the most common are described below. Fortification spectra, as might be seen in Migraine with aura. Scotoma with aspects of a fortification. Classic migraine : Migraine headache with aura (loss of vision or other visual symptoms, paresthesias, motor dysfunction) precedes the throbbing headache. 15-20% of migraines are classic (Russell and Olesen, 1996). Migraine with aura may be the first sign of CADASIL Common migraine : Migraine headache without aura. About 80% of migraines are of this type (Russell and Olesen, 1996). Vertebrobasilar migraine headache accompanied by dizziness or ataxia, hearing symptoms (other than phonophobia), nausea and vomiting, and sometimes loss of consciousness. This is rather common as about 1/3 of all persons with migraine experience true vertigo. Acephalgic migraine : Aura without headache. This diagnosis is generally made when persons who have headache and aura, also have aura without headache. Acephalgic migraines are generally thought to occur only about 1% of the time, but this is a hard number to pin down.

This is a 28 yr-old female with recurrent, frequent hemicranial throbbing headaches with nausea and a family history of similar headaches with hemiparesis. Headaches are hormonally related and examination is normal. Discuss lesion localization on the basis of the physical examination. 5th cranial nerve, vascular Discuss underlying pathogenesis on the basis of clinical course. Recurrent, episodic suggests vascular; also suggests channelopathy Indicate one likely clinical diagnosis. List (or classify) alternative diagnoses. Migraine (familial hemiplegic migraine) Other causes of headache include cluster headaches, tension headaches, raised intracranial pressure, inflammation of meninges/blood vessels. Cluster headaches occur as unilateral headaches occurring in clusters for example occurring daily for 30 minutes for a period of 6 weeks every year and are associated with tearing of one eye and running nose on the side of the headache Tension headaches occur as nonthrobbing headaches occurring intermittently associated with tightness in muscles (e.g. of neck) without nausea, precipitated by stress, with tenderness (pain on palpation) of muscles.

Extractions: RECENT PROGRESS IN DOMINANT ATAXIA RESEARCH By Dr. Ewout Brunt Groningen, Netherlands In this presentation, I will summarize existing data on dominant ataxia: I will highlight last years contribution in spinocerebellar ataxia (SCA) research before mentioning our own studies in the University of Groningen. Dominant ataxia differs from Friedreich's ataxia in that, whereas in FA too little frataxin causes a loss of function, the dominant inherited ataxias or SCA's are supposed to be caused by a gain of function. Of every gene, two copies are present. In dominant ataxia only one gene is changed, has a mutation, while the other gene is normal. Therefore, in SCA, two different products of the same gene are expressed in the body. Until now, all dominant ataxias share the same type of mutation; an abnormal expansion of a CAG-trinucleotide repeat in the coding region of the gene. The letters CAG stand for 'cytosine', 'adenine' and 'guanine', indicating the nucleic acid elements that make up the DNA strand. One copy of CAG in the DNA produces one building stone, i.e. one glutamine amino-acid, of a protein.

Extractions: Frova was released in the United States in June, 2002. Frova is very well tolerated. The long (26 hours) half-life is advantageous for those with prolonged migraines. Mean maximal blood concentrations are seen approximately 2 to 4 hours after a dose of Frova. Frova has been particularly useful for those with slower-onset moderate or moderate to severe migraines. Frova is most useful for migraines that are of slower-onset; if one awakens with a very severe migraine with severe nausea, Frova may not be the optimal choice. It is common for migraineurs to experience prolonged moderate or moderate to severe migraines. Menstrual migraines are often of long duration. Frova, with its extended duration of action, is an ideal triptan for these patients. As with any migraine abortive, early intervention with the medication is best. Frova is an outstanding first-line choice as a migraine abortive medication.

Health Report - 12/1/1997: Genes And Migraines We call it familial hemiplegic migraine. So like all other migraines youhave the headache but on top of that you have the onesided paresis. http://www.abc.net.au/rn/talks/8.30/helthrpt/stories/s360.htm
Extractions: Ann Blair-Gould: Between 10% and 12% of the population of most countries suffers from migraines, and the statistics show that it tends to occur in families although migraines are not inherited in the simple predictable manner; and that it occurs much more often in women, about 2-and-a-half-times more often than in men. So when I recently read that scientists at Leiden University here in The Netherlands had come up with a new model of how we think migraines come about, I went off to see what I could find out. I spoke there to Professor Rune Frants, who is originally from Finland, and who is head of the Department of Human Genetics at Leiden. I asked him first what we've known about what causes migraines up till now.

Extractions: Una O'Connor, who successfully studied for her Leaving Cert last year recounts her experiences and offers tips to all students with migraine on how to get through a stressful year. My headaches began when I was 13 years old. At first they were few and far between but by the time I was in my Junior Cert year, they became worse and more frequent. I went to my doctor and was diagnosed with migraine. The biggest problem was long hours of study, sitting over a desk resulting in neck strain and the stress of school and exams. I then chose to do transition year and decided to stop my medication, as this year would be stress free. I was disappointed to find my migraine attacks continued. During this year I tried many alternative treatments, which included acupuncture, allergy testing, specialised diets and relaxation therapy all of which were unhelpful. I found that cranial sacral therapy was the only alternative treatment that provided pain relief. As I began fifth year the pressure of stress and study further aggravated my first attack of hemiplegic migraine.
