18 Possible Causes for Alpha Slowing - 4-6 Hz Spikes - Myoclonus on Photic Stimulation Stage 2, lt 25 hz spike and slow waves

Did you mean: Alpha Slowing - 4-6 Hz Spikes - Myoclonus on Photic Stimulation Stage 2, lt 25 hz, 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] EEG shows classical generalized 3 Hz spike-and-slow-wave discharges.[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]

  • 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]

  • Myoclonic-Astatic Epilepsy

    EEG showed long sequences of generalised irregular spike and slow waves.[ncbi.nlm.nih.gov] The interictal EEG revealed frequent bursts of generalized 100-200 μV, 2-4 Hz spike-and-slow-wave complexes.[ncbi.nlm.nih.gov] . • EEG shows frequent generalized discharges of spike/polyspike-slow wave at varying frequencies of 2.5 to 3 Hz or higher. • Differential diagnosis is often demanding and[medlink.com]

  • 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]

  • 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]

  • 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] […] comorbidities Epilepsy with tonic-clonic seizures alone 14–20 years Tonic-clonic seizures shortly after awakening or during relaxation Fast spikes during tonic phase; bursts of spikes[amboss.com]

  • Unverricht-Lundborg Syndrome

    Later in infancy, the burst-suppression pattern is replaced by continuous multifocal spikes and slow waves of large amplitude or hypsarrhythmia, as is seen in infantile spasm[emedicine.medscape.com] Generalised spike-and-slow-wave complexes without seizures in schizophrenia.[frontiersin.org]

  • Organic Brain Syndrome

    Abstract This study addresses the prevalence of organic brain syndrome (OBS) among long-term toluene-exposed rotagravure workers who are still working. The prevalence of OBS in 22 workers exposed to toluene for a minimum of 12 years and 19 unexposed control subjects, matched for age and employment status,[…][ncbi.nlm.nih.gov]
