30 Possible Causes for Generalized Polyspikes, lt 25 hz spike and slow waves, Spike-and-Slow-Wave or Polyspike-and-Slow-Wave Discharges

Did you mean: Generalized Polyspikes, lt 25 hz, spike and slow waves, Spike-and-Slow-Wave or Polyspike-and-Slow-Wave Discharges

  • 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.[] […] variations between the spike/multispike-slow-wave relationships in generalized discharges of spike-polyspike-slow waves. (3) Predominantly brief discharges (shorter than[] The EEG has generalized spike or polyspike slow-wave complexes. JAE is a lifelong disorder, although seizures can be controlled in 70% to 80% of patients.[]

  • Myoclonic-Astatic Epilepsy

    EEG showed long sequences of generalised irregular spike and slow waves.[] Myoclonic-atonic seizures with falls are the defining symptoms. • EEG shows frequent generalized discharges of spike/polyspike-slow wave at varying frequencies of 2.5 to 3[] Analysis of the ictal EEGs showed that all attacks corresponded to the generalized spike or polyspikes-and-wave complexes.[]

  • 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[] Generalized tonic-clonic seizures, photosensitivity and generalized polyspike-wave discharges provoked by eye closure are features of both epileptic syndromes.[] Each SWD was divided into six distinct temporal phases: spike onset, spike peak, slow-wave onset, slow-wave ascending, slow-wave peak, and slow-wave descending phases.[]

  • Epilepsy

    Generalized polyspike-slow wave in EEG was common to see in myoclonic seizure and can help to make the classification.[] waves.[] ) discharges or generalized spike wave and polyspike wave activity.[]

  • 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[] […] spike-and-wave, or generalized polyspike-and-wave complexes.[] EEG: Usually normal background, with generalized spike and wave or generalised polyspike and wave.[]

  • 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[] We randomly selected 10 generalized spike/polyspike and wave complexes (GSW) for each BAFME patient and measured the duration of them.[] Electroencephalograms showed generalized spikes or polyspikes and wave complexes, and some patients exhibited photosensitivities.[]

  • West Syndrome

    […] and slow-wave activity ( Gibbs and Gibbs 1952 ).[] The generalized tonic seizures began with bi-frontal polyspikes on EEG. Our diagnosis was lissencephaly presenting with West syndrome and generalized tonic seizures.[] Interictal EEG displays diffuse and asynchronous high voltage spikes and slow waves suggesting the hypsarrhythmic pattern. B.[]

  • Idiopathic Generalized Epilepsy

    These patients had no family history of epilepsy, normal neurological evaluation, normal neuroimaging, interictal EEG showing generalized spike- and polyspike-wave discharges[] […] 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[] EEG usually shows bilateral, synchronous generalized spike-and-wave (GSW) or polyspike-and-wave discharges with a normal background.[]

  • Early Infantile Epileptic Encephalopathy Type 3

    West Syndrome (WS) aka as infantile spasms with hypsarrhythmia, EEG abnormality with asynchronous very high amplitude, irregular, continuous multifocal spike an slow wave[] .  Inter-Ictal EEG  Initial -20% show normal BG with photoparoxysmal discharges of spikes/ polyspikes-slow waves.  Within 1 year, EEG - abnormal slow BG with frequent asymmetrical[] Developmental delay 37 (100.0) Tone abnormalities 18 (48.6) Microcephaly 10 (27.0) Hemiplegia 2 (5.4) Visual defects 4 (10.8) Hearing deficit 1 (2.7) Neuroimaging Normal 9 (24.3) Generalized[]

  • Lennox-Gastaut Syndrome

    Interictal EEG may demonstrate the following characteristics: A slow background that can be constant or transient Awake – Diffuse slow spike wave Non-REM sleep – Discharges[] Interictal EEG showed findings characteristic of LGS: generalized slow spike-wave complexes, multifocal sharp waves, generalized polyspikes and paroxysmal fast activity during[] polyspikes or fast rhythms during sleep (required especially when daily tonic seizures are obscure), and (3) diffuse slow (  2.5 Hz) spike-wave complex on EEG.[]
