WebbWhat does it mean when an EEG shows spikes, sharp, or slow waves? First it’s important to realize that it may mean something very different for each person. Some waveforms or activity on an EEG are normal, while others may be within normal limits for some people but not others. Spikes or sharp waves are terms commonly seen in EEG reports. WebbSpike and wave discharges (SWDs) are the electrographic hallmark of absence seizures and the major diagnostic criterion for childhood absence epilepsy (CAE). In a widely …

Webb11 jan. 2024 · Spike wave epileptiform discharges (and seizures) may occur in any severe encephalopathy, but are said to be more common than in uraemic encephalopathy and in insulin coma. In hypoglycaemia there may be generalised slow activity or focal/lateralised δ rhythms, and these may be associated with focal neurological deficits. WebbThis epilepsy is also known as CSWS or epilepsy with continuous spike-wave during slow wave sleep. This syndrome is a very rare form of epilepsy, affecting 1 out of 200 (0.5%) children with epilepsy. CSWS may start in children between 2 and 12 years of age, most often between 4 and 5 years of age. the panorama jersey

WebbDescription Lennox-Gastaut syndrome is a severe condition characterized by recurrent seizures (epilepsy) that begin early in life. Affected individuals have multiple types of seizures, a particular pattern of brain activity (called slow spike-and-wave) measured by a test called an electroencephalogram (EEG), and impaired mental abilities.
