  • Early Infantile Epileptic Encephalopathy Type 3

    ., multifocal spike- and sharp-wave discharges, repetitive paroxysmal activity, unusually low-voltage fast activity, and findings consistent with complex partial seizures[graphyonline.com]

  • Generalized Clonic or Tonic-Clonic Seizures

    The EEG shows generalised spike and wave discharges of 3 to 4 Hz and some with photic sensitivity. This is potentially a lifelong epilepsy.[pennsw.com.au]

  • Juvenile Myoclonic Epilepsy

    Interictal electroencephalography (EEG) in JME shows interictal epileptiform discharges such as generalized spikes, polyspikes, bilateral-synchronous 4-6/s spike-wave complexes[go.galegroup.com] Myoclonic jerks appear to be time-locked to generalized 3-5 Hz spike-and wave complexes [8]. Photoparoxysmal response was seen in 40% of patients.[go.galegroup.com]
