Did you mean: lt 25 hz, spike and slow waves, Paroxysmal Activity - Spikes, Spike-and-Slow-Wave or Polyspike-and-Slow-Wave Discharges

  • Juvenile Absence Epilepsy

    The discharge is heterogeneous, often asymmetrical and may include irregular spike and slow wave complexes, fast and other paroxysmal activity.[en.wikipedia.org] 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] […] variations between the spike/multispike-slow-wave relationships in generalized discharges of spike-polyspike-slow waves. (3) Predominantly brief discharges (shorter than[medlink.com]

  • Myoclonic-Astatic Epilepsy

    - or polyspike-wave activity at more than 2.5 Hz without generalized paroxysmal fast activity or focal spikes.[jamanetwork.com] EEG showed long sequences of generalised irregular spike and slow waves.[ncbi.nlm.nih.gov] 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[medlink.com]

  • Epilepsy

    At 9 years, video EEG monitoring showed a striking pattern of interictal slow spike-wave and paroxysmal fast activity, maximal over the right, initially unaffected, hemisphere[ncbi.nlm.nih.gov] waves.[ncbi.nlm.nih.gov] ) discharges or generalized spike wave and polyspike wave activity.[brain.oxfordjournals.org]

    This was referred to as posterior paroxysmal activity by Holmes et al.[euroformhealthcare.biz] […] 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] Paroxysmally, rhythmic θ-activity at 4 to 5 Hz appears in the centroparietal areas, as do fast bilateral spike-waves, which may be associated later with variable focal or[neupsykey.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]

  • 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] 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.[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]

  • Idiopathic Generalized Epilepsy

    Generalized spike-wave discharges and diffuse paroxysmal fast activity were categorized as interictal and ictal, based on duration of less than 10 seconds or greater, respectively[ncbi.nlm.nih.gov] […] 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]

B.[bmcneurol.biomedcentral.com] It associates IS with a typical EEG pattern called hypsarrhythmia consisting of random, high-voltage, nonsynchronous spikes and slow waves and developmental delay.[nature.com]
