WebIn LGS, interictal EEG reveals the hallmark pattern of diffuse, slow spike waves characterized by bursts of irregular and generalized spikes or sharp waves. These are followed for 35 to 400 milliseconds by symmetrical or asymmetrical sinusoidal slow waves with a frequency of 1.5 to 2.5 Hz and a 200- to 800-microvolt amplitude. 5 WebSlow spike-wave activity in EEG and associated clinical features: often called 'Lennox' or "Lennox-Gastaut' syndrome Clinical features were studied in 83 patients with slow spike …

WebNov 30, 2024 · Epileptiform Discharges. The best-known biomarker of hyperexcitability in humans is the epileptiform discharge, which is defined as a paroxysmal EEG graphoelement (spike or sharp wave) with a duration of 20–200 ms that is clearly distinct from ongoing background EEG activity followed by slow waves (Noachtar and Remi, 2009) (Figure … WebOct 11, 2006 · EEG showing generalized spike and wave discharge at 3–4 Hz.
