584 Possible Causes for Epileptiform Activity, Hyperreninemia, Slowing with Polyspike-and-Slow-Waves

  • Hyponatremia

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

  • Traumatic Brain Injury

  • Epilepsy

    It remains unclear whether seizures and epileptiform activity on the EEG are causative or comorbid.[] EEG recordings showed a variety of changes: generalized spike wave and polyspike wave activity, focal discharges, focal or diffuse slowing or were normal.[] 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.[] The cerebral cortex is the only area from which epileptiform activity arises with any frequency.[] Levetiracetam may selectively prevent hypersynchronization of epileptiform burst firing and propagation of seizure activity.[]

  • Temporal Lobe Epilepsy

    However, little is currently known about the modulation of these networks by epileptiform activity, such as interictal spikes and seizures.[] […] complex, polyspikes, runs of rapid spikes, sharp waves, sharp-and-slow-wave complex, slow sharp waves, spikes and spike and slow waves.[] Neurophysiologic findings in NTLE are typically a predominance of lateral temporal interictal epileptiform activity (IEA) and an ictal onset pattern consisting of irregular[]

  • Juvenile Myoclonic Epilepsy

    The electro encephalogram revealed generalised polyspike and wave epileptiform activity with photosensitivity.[] SIGNIFICANCE: These findings implicated the abnormality of thalamomotor cortical network in JME which were associated with the genesis and propagation of epileptiform activity[] Among nonrapid eye movement (NREM) sleep stages, EEG epileptiform activity was maximal during stages III and IV.[]

  • Idiopathic Generalized Epilepsy

    Wicket spikes (WS) are a normal variant EEG pattern that sometimes can be mistaken for epileptiform activity.[] […] and waves with frontocentral predominance Interictal EEG : 4–6 Hz bilateral polyspike and slow wave Responds well to antiseizure drug therapy; seizures become less frequent[] Forty patients out of 249 (16.1%) had increased epileptiform activity during activation procedures.[]

  • Continuous Spike-and-Slow-Waves during Sleep

    Specific cutoff thresholds or measurement methods for epileptiform activity frequency have yet to be defined.[] […] paroxysms of polyspikes or spikes-slow waves.  Ictal EEG  Varies according to seizure type. 16.[] , slow waves or any of the combination e.g.[]

  • Stroke

    The first EEG background activity asymmetry and first EEG with interictal epileptiform activity were independent predictors of poststroke epilepsy during the first year after[] Key words: abnormal EEG, non-epileptiform abnormalities, slow activity.[] Periodic Lateralized Epileptiform Discharges (PLEDs) are EEG abnormalities that signify acute brain dysfunction or unilateral brain lesion, usually destructive in nature,[]

  • Benign Adult Familial Myoclonic Epilepsy

    .  No associated brain pathology  Typically some improvement in neurological status once epileptiform activity has resolved. 40.  Severe myoclonic epilepsy or severe polymorphic[] Following a first unprovoked seizure, unequivocal epileptiform activity shown on EEG can be used to assess the risk of seizure recurrence.[] This is similar to epileptiform activity admixed into vertex waves and sleep spindles, called dyshormia by Niedermeyer (Fig. 1).[]
