  • Lennox-Gastaut Syndrome

    Interictal EEG showed findings characteristic of LGS: generalized slow spike-wave complexes, multifocal sharp waves, generalized polyspikes and paroxysmal fast activity during[ncbi.nlm.nih.gov] In fact, 10/24 cases showed normal sleep transients with presence of symmetric vertex sharp waves in stage 1 non-REM sleep and also symmetric and well structured sleep spindles[omicsonline.org] Also during sleep interictal background activity may be normal.[omicsonline.org]

  • Rolandic Epilepsy

    Differential diagnosis Occipital spikes, like other focal spikes, can exist without clinical epilepsy. They can also be noted in children with visual impairment.[emedicine.com] Differential diagnosis Differential diagnosis includes other idiopathic focal childhood epilepsies (benign childhood occipital epilepsy, Panayiotopoulos type and Gastaut type[orpha.net] spikes (Gastaut type).[emedicine.com]

  • Idiopathic Generalized Epilepsy

    The EEG signature of IGE is bisynchronous, symmetric, and generalized spike-wave complex; although focal, irregular, and so called "fragments" of discharges are not uncommon[ncbi.nlm.nih.gov] Other characteristic EEG features include polyspikes, polyspike-wave discharges, occipital intermittent rhythmic delta activity, and photoparoxysmal response.[ncbi.nlm.nih.gov]

  • Generalized Clonic or Tonic-Clonic Seizures

    ‘Contrary to popular folk belief, nothing should be placed in the mouth during the seizure. Severe injury could occur.’ Generalized tonic clonic seizures (grand mal seizures) are the most common and best known type of generalized seizure. They begin with stiffening of the limbs (the tonic phase), followed by jerking[…][epilepsynw.org]
