Did you mean: 3-4 Hz Spikes, Genetic, Heterogeneity, Multifocal Independent Spikes

  • Benign Adult Familial Myoclonic Epilepsy

    Abstract Benign adult familial myoclonic epilepsy (BAFME) has been mapped to chromosome 8q24; however, genetic heterogeneity has been recently suggested.[ncbi.nlm.nih.gov] Childhood absence epilepsy with tonic-clonic seizures and electroencephalogram 3-4-Hz spike and multispike-slow wave complexes: linkage to chromosome 8q24.[reference.medscape.com] This observation would confirm that BAFME is a worldwide, genetically heterogeneous condition, probably with Japanese families linked to 8q24 and European families to 2p11.1[ncbi.nlm.nih.gov]

  • Juvenile Myoclonic Epilepsy

    Abstract Juvenile myoclonic epilepsy (JME) is a clinically and genetically heterogenous, generalized epilepsy syndrome usually starting in adolescence.[ncbi.nlm.nih.gov] Interictal electroencephalography (EEG) in JME shows interictal epileptiform discharges such as generalized spikes, polyspikes, bilateral-synchronous 4-6/s spike-wave complexes[go.galegroup.com] BACKGROUND: Juvenile myoclonic epilepsy (JME), is an early-onset inherited generalized epilepsy which displays genetic heterogeneity, with at least 10 known loci.[ncbi.nlm.nih.gov]

  • Epilepsy

    Progressive myoclonic epilepsies (PME) are a clinically and genetically heterogeneous group of rare diseases characterized by myoclonic seizures, tonic-clonic seizures, and[ncbi.nlm.nih.gov] […] to 8 years of age, in an otherwise apparently healthy child. 3 The classic electroencephalogram (EEG) shows generalized spike-wave bursts (of 3 Hz) with normal background[doi.org] This observation along with our previous findings of hot water genetic loci at 10q21.3-q22.3 (OMIM: 613339) and 4q24-q28 (OMIM: 613340), indicates unanticipated genetic heterogeneity[ncbi.nlm.nih.gov]

  • Idiopathic Generalized Epilepsy

    The lack of significant association evidence of single variants with disease in this two-stage approach emphasizes the high genetic heterogeneity of epilepsy disorders, suggests[ncbi.nlm.nih.gov] 4 Hz spikes and waves in all regions of the brain 1 st -line : valproic acid Avoid triggers : sleep deprivation, alcohol, drugs, flickering lights 60% are seizure -free under[amboss.com] […] etiology, where heterogeneous combinations of genetic factors determine the disease phenotype.[ncbi.nlm.nih.gov]

  • Myoclonic-Astatic Epilepsy

    In a clinical setting, the occurrence of periodic clusters and independent focal or multifocal accentuations of generalized spike-and-wave complexes in interictal EEG may[ncbi.nlm.nih.gov] […] influences and clues for genetic heterogeneity, and discuss strategies that may be helpful in elucidating the etiology of MAE in light of current genetic techniques.[ncbi.nlm.nih.gov] […] presence of generalized spike- or polyspike-wave EEG discharges at 2-3 Hz, without focal spike discharges; and (4) exclusion of severe and benign myoclonic epilepsy (SME,[ncbi.nlm.nih.gov]

  • West Syndrome

    Other patterns, such as multifocal independent spike discharges (MISD), are present in the remainder.[ncbi.nlm.nih.gov] West syndrome is genetically heterogeneous, and its genetic causes have not been fully elucidated.[ncbi.nlm.nih.gov] This disorder is genetically heterogeneous, with up to a fifth of cases resulting from mutations in the CDKL5 gene.[genedx.com]

  • Generalized Clonic or Tonic-Clonic Seizures

    Genetic Heterogeneity of Progressive Myoclonic EpilepsyProgressive myoclonic epilepsy refers to a clinically and genetically heterogeneous group of neurodegenerative disorders[mendelian.co] The EEG shows generalised spike and wave discharges of 3 to 4 Hz and some with photic sensitivity. This is potentially a lifelong epilepsy.[pennsw.com.au] Genetic Heterogeneity of Mosaic Variegated Aneuploidy SyndromeSee also MVA2 ( OMIM ), caused by mutation in the CEP57 gene ( OMIM ) on chromosome 11q21, and MVA3 ( OMIM ),[mendelian.co]

  • Juvenile Absence Epilepsy

    Página 112 - JC (1998) Autosomal dominant nocturnal frontal-lobe epilepsy: genetic heterogeneity and evidence for a second locus at 15q24. Am. J. Hum.[books.google.es] Diagnostic methods Diagnosis relies on the clinical features and on electroencephalogram (EEG) recorded awake and during sleep, that displays a generalized 3-4 Hz spike-and-slow-wave[orpha.net] Generalized 3-4 Hz spike or polyspike slow-wave complexes. Neuro Imaging: Not usually required. Mainly from other IGEs such as CAE or Juvenile Myoclonic Epilepsy (JME).[pennsw.com.au]

  • Encephalopathy

    SUMMARY: Neonatal encephalopathy is a heterogeneous disorder that is characterized by alterations in mental status, hypotonia, seizures, and abnormalities in feeding and respiration[ncbi.nlm.nih.gov] Posterior reversible encephalopathy syndrome (PRES) is a rare neurologic condition that manifests with heterogeneous clinical findings, including altered mental status, seizure[ncbi.nlm.nih.gov] LESSONS: HE may cause highly heterogeneous clinical features, particularly MRI findings.[ncbi.nlm.nih.gov]

  • Lennox-Gastaut Syndrome
