Slow spike and wave
WebbSlow spike waves may occur during seizure or between seizures, or may occur in absence of any observable clinical changes which helps distinguish pattern from extended 3-Hz spike-wave discharges. [citation needed] Ocular abnormality [ edit] Ocular abnormalities affect around 90% of children. Webb21 okt. 2011 · Figure 1: Human electroencephalogram (EEG) recording of an absence seizure consisting of slow (about 3 Hz) oscillations with spike-and-wave patterns. The EEG was taken from a 24-hour recording of a 10 year-old child with no treatment (original data from Destexhe, 1992). The term spike-and-wave refers to a pattern of the …

WebbDuring slow sleep, bursts of more synchronous polyspikes and waves often appear. In West syndrome, spasms, hypsarrhythmia, and cognitive deterioration occur together. … Webb11 okt. 2006 · Generalized spike–wave discharges often fragment and become more irregular in rate during sleep. Some IEDs are activated by sleep. The rate of occurrence of slow spike and wave discharges, centrotemporal spikes, and 3 Hz spike and wave discharges increases during slow wave sleep.
WebbEpilepsy with continuous spike waves during slow-wave sleep (CSWS) has a heterogeneous clinical presentation and presents in childhood, often associated with … 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. SSW and GPFA usually emerge between ages 3-5 years but can begin later in childhood. SSW and GPFA, which occur between seizures, worsen seizures, development, and behavior … WebbEpilepsy features include seizure onset usually between ages three and six years, focal epilepsy with language and/or global developmental regression, and electroencephalogram (EEG) showing continuous spike-and-wave discharges in sleep or very active centrotemporal discharges.

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.
