Spike-and-wave is a pattern of the electroencephalogram (EEG) typically observed during epileptic seizures. A spike-and-wave discharge is a regular, symmetrical, generalized EEG pattern seen particularly during absence epilepsy, also known as ‘petit mal’ epilepsy.

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.

WebbAn example of a monophonic wave is a simple spike. A biphasic wave starts on one side of the baseline with an up slope and downslope going through the baseline, but then has a second part that crosses the baseline again; the classic epileptiform spike and slow wave discharge is an example of a biphasic wave. Polyphasic waves cross the baseline ... Webb10 apr. 2024 · So XBBs have slow increase and low decrease. Adding this to the "variant soup " => never comes back to zero. XBB.1.16 is crazy because of the sharp exponential increase. This one could do a real new wave. I think it's because of its super immune escape (vaccine+antivirals)

WebbSlow spike and wave (SSW) and Generalized Paroxysmal Fast Activity (GPFA) are seen on the EEG. These are the hallmarks of LGS. Diagnosis of LGS requires an EEG test.
