Did you mean: Generalized Spike-and-Slow-Waves, 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

    The interictal EEG revealed frequent bursts of generalized 100-200 μV, 2-4 Hz spike-and-slow-wave complexes.[] 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[]

  • Epilepsy

    Electroencephalography (EEG) showed progressively slowed background activity and sporadic generalized spike-and-wave discharges.[] waves.[] ) discharges or generalized spike wave and polyspike wave activity.[]

  • Generalized Clonic or Tonic-Clonic Seizures

    , 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.[] […] 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[] 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[]

  • Juvenile Myoclonic Epilepsy

    […] multiple spike and spike slow wave discharges (in an untreated patient).8 The possible factors responsible for the delay in the diagnosis of JME were studied retrospectively[] 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[] 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.[]

  • Benign Adult Familial Myoclonic Epilepsy

    , high-amplitude spike and slow-wave complexes 3.5 Hz, typically 4 s duration.  Absence seizures in JAE are more sporadic.  EEG is slightly faster with generalized spike[] In 1824, Calmeil used the term absence . [2] In 1935, Gibbs, Davis, and Lennox described the association of impaired consciousness and 3-Hz spike-and-slow-wave complexes on[] Ten- to 16-Hz rapid spikes with slow waves occur with myoclonic seizures, photosensitivity is common, and abnormalities may occur in sleep. 3.1.7.[]

  • Early Infantile Epileptic Encephalopathy Type 6

    Four children had generalized spike and slow wave or polyspike and slow wave.[] […] and slow wave pattern of 1.5 to 2 Hz, [and it has] different seizure types.[] During disease progression and increased seizure frequency, however, EEG findings eventually reveal both focal and multifocal anomalies, including generalized spike-and-wave[]

  • West Syndrome

    Lennox-Gastaut Syndrome: LGS is characterized by multiple types of seizures and an abnormal EEG with generalized slow spikewave discharges.[] […] and slow-wave activity ( Gibbs and Gibbs 1952 ).[] Interictal EEG recording during n-REM sleep and wakefulness displayed diffuse and asynchronous high voltage spikes and slow waves suggesting the hypsarrhythmic pattern (Figure[]

  • Idiopathic Generalized Epilepsy

    […] epilepsy K complex lambda mu OIRDA PLEDs phantom spike and wave photic driving photoparoxysmal response photomyogenic artifact poly spike and wave posterior dominant rhythm[] […] 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[] Panayiotopoulos et al. (1994) [21] observed that 51.5% of patients had spike/multiple spike-slow wave discharges.[]

  • Early Infantile Epileptic Encephalopathy Type 3

    EEG demonstrates primarily burst-suppression patterns in the neonatal period, hypsarrhythmia in infancy, and slow generalized spike-wave discharges in early childhood.[] 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[]
