142 Possible Causes for lt 25 hz spike and slow waves, Spike-and-Slow-Waves

Did you mean: lt 25 hz, spike and slow waves, Spike-and-Slow-Waves

  • Juvenile Absence Epilepsy

    All patients had minimum twice EEG recordings and all had typical 3-Hz generalized spike and slow-wave discharges at least on one EEG.[ncbi.nlm.nih.gov] There may be generalized spike-and-wave, fragments of generalized spike-and-wave, or polyspike-and-wave. Caution .[medlink.com] 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]

  • Myoclonic-Astatic Epilepsy

    EEG showed long sequences of generalised irregular spike and slow waves.[ncbi.nlm.nih.gov] At age four, a video-EEG-recording showed frequent head nodding (atonic seizures) and myoclonic astatic seizures associated with diffuse spikes or polyspikes and waves.[ncbi.nlm.nih.gov] Furthermore, data of spike-wave complexes ranging in frequency 4-7 Hz tend to accompany photosensitivity. Parietal theta and background slowing are also present in EEG.[symptoma.com]

  • Generalized Clonic or Tonic-Clonic Seizures

    […] generalized high-amplitude, poly spike discharges." [2] The clonic phase EEG will show "high amplitude activity that is typically interrrupted by slow waves to create a spike-and-slow-wave[en.wikipedia.org] , poly spike discharges." [2] The clonic phase EEG will show "high amplitude activity that is typically interrrupted by slow waves to create a spike-and-slow-wave pattern.[en.wikipedia.org] According to "Harrisons Manual of Medicine," the EEG during the tonic phase will show a "progressive increase in low-voltage fast wave activity, followed by generalized high-amplitude[en.wikipedia.org]

  • Juvenile Myoclonic Epilepsy

    We applied dipole modeling and brain distributed source analysis to find current sources comprising spikes and slow waves of polyspike and wave complexes (PSWC) in patients[ncbi.nlm.nih.gov] The spike-peak and slow-wave onset phases did not show a consistently dominant outflow region.[ncbi.nlm.nih.gov] The discharge is frequently short and fragmented, the spike and slow wave complexes show interdischarge frequency variations with multiple spikes and other characteristics[neurologyindia.com]

  • Epilepsy

    waves.[ncbi.nlm.nih.gov] […] and slow waves); (d) occurrence at any age in childhood and adulthood; (e) frequently demonstrable aetiology (tumor, vascular); and (f) no progressive evolution of the syndrome[medlink.com] Electroencephalography showed spike-slow waves and slow waves with mixed asynchronized spike waves originating from the frontal lobe during the sleep stage.[ncbi.nlm.nih.gov]

  • Benign Adult Familial Myoclonic Epilepsy

    […] and slow-wave complexes at 3 Hz associated with myoclonus.  Interictal EEG is variable and ranges from normal to background slowing and generalized spike and slow-wave activity[slideshare.net] The onset may be difficult to discern, and postictal EEG slowing may be noted. Slow spike-and-wave discharges (2.5 Hz).[reference.medscape.com] Slow spike and wave with fast activity in sleep. Eleven-year-om gm with LGS.[euroformhealthcare.biz]

  • West Syndrome

    […] and slow-wave activity ( Gibbs and Gibbs 1952 ).[medlink.com] Ictal EEG shows a myoclonic jerk of the upper limbs, synchronous with the generalized discharges of 4 Hz spike-wave.[bmcneurol.biomedcentral.com] Interictal The background EEG is often highly disorganized with high voltage irregular slow waves intermixed with multifocal spikes and polyspikes, this is termed 'hypsarrhythmia[epilepsydiagnosis.org]

  • Focal Epilepsy - Speech Disorder - Mental Retardation

    […] and slow-wave discharge indicated by EEG and the discharge index during slow wave sleep 85%; d. local lesions or extensive spike and slow waves in waking state indicated[jitm.hk] Key words: epilepsy with continuous spike-waves during slow wave sleep, EEG, sleep.[scielo.br] We also learned that Joshua not only had ESES on his EEG, but that Joshua had near continuous spike and slow wave activity 85% of the time he was asleep every night for the[complexchild.org]

  • Idiopathic Generalized Epilepsy

    […] and slow waves during clonic phase 70% are seizure -free under treatment In some cases, no medical therapy is necessary avoid triggers Epilepsy with myoclonic-atonic seizures[amboss.com] Panayiotopoulos et al. (1994) [21] observed that 51.5% of patients had spike/multiple spike-slow wave discharges.[annalsofian.org] […] and wave photic driving photoparoxysmal response photomyogenic artifact poly spike and wave posterior dominant rhythm POSTs RMTTD sawtooth waves SIRPIDs sleep spindles slow[eegatlas-online.com]

  • Early Infantile Epileptic Encephalopathy Type 6

    […] and slow wave pattern of 1.5 to 2 Hz, [and it has] different seizure types.[neurologylive.com] Four children had generalized spike and slow wave or polyspike and slow wave.[neurology.org] At onset, EEG is usually normal but later spikes or poly spike-waves with a slowing of background activity are noted as well as multifocal discharges.[orpha.net]
