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

Did you mean: 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.[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] […] seen in children, are characterized by a sudden and brief absence of consciousness lasting up to 20 seconds, with intense neuroelectrical activities in the brain, called spike-and-slow[dovemed.com]

  • Epilepsy

    waves.[ncbi.nlm.nih.gov] ) discharges or generalized spike wave and polyspike wave activity.[brain.oxfordjournals.org] Cigdem Inan Akman, Nonconvulsive Status Epilepticus and Continuous Spike and Slow Wave of Sleep in Children, Seminars in Pediatric Neurology, 17, 3, (155), (2010).[doi.org]

  • Absence Seizure

    Ictal - EEG is of slow (less than 2.5 Hz) spike and slow wave.[en.wikipedia.org] 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[emedicine.com] The discharge is heterogeneous, often asymmetrical and may include irregular spike and slow wave complexes, fast and other paroxysmal activity.[en.wikipedia.org]

  • Myoclonic-Astatic Epilepsy

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

  • 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]

  • 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] 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[reference.medscape.com] 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.[euroformhealthcare.biz]

  • Tonic-Clonic Seizure

    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] […] 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]

  • 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] […] an epileptic encephalopathy—[it’s] very, very difficult to control the condition—that’s characterized by an abnormal pattern on the EEG [electroencephalogram] with a slow spike[neurologylive.com]

  • West Syndrome

    […] and slow-wave activity ( Gibbs and Gibbs 1952 ).[medlink.com] Interictal EEG displays diffuse and asynchronous high voltage spikes and slow waves suggesting the hypsarrhythmic pattern. 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]
