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[epilepsydiagnosis.org]
The most common EEG pathology was focal slowing (30; 43.5%). No epileptiform potentials were found.[ncbi.nlm.nih.gov]
[…] tumors increases the possibility of detection of epileptiform discharges) 16.[scielo.br]
Epilepsy
The cellular neurophysiologic correlate of an interictal focal epileptiform discharge in single cortical neurons is the paroxysmal depolarization shift (PDS).[emedicine.medscape.com]
(EEG) hallmark of focal-onset seizures is the focal interictal epileptiform spike or sharp wave.[emedicine.medscape.com]

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.[…][ncbi.nlm.nih.gov]
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[epilepsydiagnosis.org]

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[scielo.br]
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[ncbi.nlm.nih.gov]
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.[mdedge.com]
Idiopathic Generalized Epilepsy
The aim of this work is to investigate focal interictal epileptiform discharges (IEDs) in IGEs, and their relation to clinical variables.[ncbi.nlm.nih.gov]
Focal changes in the electroencephalography (EEG) have been reported in IGEs.[ncbi.nlm.nih.gov]
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.[ncbi.nlm.nih.gov]
Familial Infantile Myoclonic Epilepsy
Interictal EEGs in the active phase were either normal or showed focal epileptiform discharges in posterior or central regions.[pediatricneurologybriefs.com]
Temporal Lobe Epilepsy
., abnormally increased paired‐pulse suppression and an abnormally high resistance to generating epileptiform discharges in response to afferent stimulation.[doi.org]
Ictal EEG usually demonstrates epileptiform activity over the temporal areas. Prognosis and Treatment The course of autosomal dominant focal epilepsy is variable.[doctorstrizhak.com]
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[doi.org]
