109 Possible Causes for Focal Epileptiform Discharges

  • Stroke

    Ictal The presence of focal, rhythmic epileptiform discharges is the most characteristic feature of the scalp EEG in patients with focal seizures, showing spatial correlation[] The most common EEG pathology was focal slowing (30; 43.5%). No epileptiform potentials were found.[] […] tumors increases the possibility of detection of epileptiform discharges) 16.[]

  • Epilepsy

    The cellular neurophysiologic correlate of an interictal focal epileptiform discharge in single cortical neurons is the paroxysmal depolarization shift (PDS).[] (EEG) hallmark of focal-onset seizures is the focal interictal epileptiform spike or sharp wave.[] For a review, see the epilepsy book of Rho, Sankar, and Cavazos. [5] For a more recent review, see Kramer and Cash. [6] Pathophysiology of focal seizures The electroencephalographic[]

  • Neonatal Seizures

    Herein we report a case of a male infant with hyperekplexia. He was born after an uneventful pregnancy to healthy unrelated parents. At 2 days, he began to have frequent episodes of apnea accompanied with generalized tonic posture. Phenobarbital had been prescribed for the suspicion of neonatal seizures.[…][]

  • Hypoxic-Ischemic Brain Injury

    Ictal In the presence of focal seizures, focal rhythmic epileptiform discharges are seen, showing spatial correlation with the area of brain injury from which focal seizures[] […] tumors increases the possibility of detection of epileptiform discharges) 16.[] Epileptiform discharges can coexist with focal slow activity produced by brain tumors, especially slow growth (the least destruction of the brain parenchyma with slow growth[]

  • Hyperventilation

    Children (with HIHARS) who presented with clinical features suggestive of GTCS or focal motor seizures (with or without blank spells) and/or had epileptiform discharges on[]

  • Focal Onset Impaired Awareness Seizure

    DEFINITIONS The hallmark of partial seizures in children and adults is focal epileptiform discharges localized to a portion of one cerebral hemisphere.[]

  • Idiopathic Generalized Epilepsy

    The aim of this work is to investigate focal interictal epileptiform discharges (IEDs) in IGEs, and their relation to clinical variables.[] Focal changes in the electroencephalography (EEG) have been reported in IGEs.[]

  • Early Infantile Epileptic Encephalopathy

    By increasing recording sensitivity, we detected focal epileptiform discharges of slow rhythmic sharp and slow waves building to 30 microV during suppression periods.[]

  • Familial Infantile Myoclonic Epilepsy

    Interictal EEGs in the active phase were either normal or showed focal epileptiform discharges in posterior or central regions.[]

  • Temporal Lobe Epilepsy

    ., abnormally increased paired‐pulse suppression and an abnormally high resistance to generating epileptiform discharges in response to afferent stimulation.[] Ictal EEG usually demonstrates epileptiform activity over the temporal areas. Prognosis and Treatment The course of autosomal dominant focal epilepsy is variable.[] Focal application of the γ‐aminobutyric acid type A (GABA A ) receptor antagonist bicuculline methiodide within the dentate gyrus abolished the abnormally increased paired‐pulse[]
