869 Possible Causes for Epileptiform Activity, Hyperreninemia, Spike-and-Slow-Waves

  • Epilepsy

    It remains unclear whether seizures and epileptiform activity on the EEG are causative or comorbid.[] […] predominance, and multifocal spike-and-slow waves.[] Through an accurate Video-EEG polygraphic analysis, we demonstrated that seizures are related to an abnormal increase of epileptiform activity after eye-closure or loss of[]

  • Generalized Clonic or Tonic-Clonic Seizures

    epileptiform activity.[] , 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.[] The cerebral cortex is the only area from which epileptiform activity arises with any frequency.[]

  • Epilepsy with Continuous Spike-and-Slow-Waves during Sleep

    Specific cutoff thresholds or measurement methods for epileptiform activity frequency have yet to be defined.[] الصفحة 36 - Yagi K (1989): Clinical relevance of continuous spike-waves during slow wave sleep.[] Electrical status epilepticus during slow sleep (ESES) was proposed by Tassinari et al. in 1971 for a particular EEG pattern characterized by diffuse spike-waves occurring[]

  • Continuous Spike-and-Slow-Waves during Sleep

    Specific cutoff thresholds or measurement methods for epileptiform activity frequency have yet to be defined.[] Key words: epilepsy with continuous spike-waves during slow wave sleep, EEG, sleep.[] epileptiform activity on the patient are unclear.[]

  • Juvenile Myoclonic Epilepsy

    The electro encephalogram revealed generalised polyspike and wave epileptiform activity with photosensitivity.[] The spike-peak and slow-wave onset phases did not show a consistently dominant outflow region.[] SIGNIFICANCE: These findings implicated the abnormality of thalamomotor cortical network in JME which were associated with the genesis and propagation of epileptiform activity[]

  • Idiopathic Generalized Epilepsy

    Wicket spikes (WS) are a normal variant EEG pattern that sometimes can be mistaken for epileptiform activity.[] Panayiotopoulos et al. (1994) [21] observed that 51.5% of patients had spike/multiple spike-slow wave discharges.[] […] during tonic phase; bursts of spikes and slow waves during clonic phase 70% are seizure -free under treatment In some cases, no medical therapy is necessary avoid triggers[]

  • Temporal Lobe Epilepsy

    However, little is currently known about the modulation of these networks by epileptiform activity, such as interictal spikes and seizures.[] Video electroencephalography showed that the seizure was associated with a high-amplitude spike and slow wave, originating from the right anterior temporal region and extending[] […] complex, polyspikes, runs of rapid spikes, sharp waves, sharp-and-slow-wave complex, slow sharp waves, spikes and spike and slow waves.[]

  • Rolandic Epilepsy

    This impairment could be correlated with the amount of nocturnal epileptiform activity.[] In an EEG, characteristically high spikes with deflections in two directions (biphasic spikes) followed by slow waves can be found above the middle temporal lobe (centrotemporal[] The stimulus was delivered to the first finger of the right hand using a tendon hammer, which evoked a single spike followed by a slow wave, showing the maximal amplitude[]

  • Panayiotopoulos Syndrome

    EEG revealed an abnormal pattern with recurrent multifocal epileptiform activity over the bilateral occipital and frontal regions during sleep.[] An outpatient EEG 6 months later showed abundant multifocal, predominantly posterior, as well as irregular generalized spike-and-slow-wave discharges on normal background[] During non-rapid eye movement (NREM) sleep, the EEG showed epileptiform activity of continuous spike-wave greater than 85% ( Fig 2 ).[]

  • Hyponatremia

    In this setting, release of both antidiuretic hormone (ADH) (increases renal permeability to water) and renin (increases renal sodium retention) occurs.[]
