Eeg with epileptiform discharges
WebThe purpose of this study was to analyze the clinical aspects in 130 patients presenting periodic lateralized epileptiform discharges (PLEDs) in their EEG and to compare these results with those found in the literature. Etiology, neurologic deficit, seizure occurrence, and evolution were studied in each patient by historical review. WebNov 30, 2024 · 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 1A).

WebOct 11, 2006 · The EEG is examined for a specific epileptiform abnormality, the interictal spike or sharp wave. For a transient to be deemed as a specific interictal epileptiform discharge, several criteria ( 2) must be fulfilled ( Table 2 ). These discharges may be either generalized or focal in distribution ( Figs. 1 and 2 ). WebSpike-and-wave discharge (SWD) pattern detection in electroencephalography (EEG) is a crucial signal processing problem in epilepsy applications. It is particularly important for overcoming time-consuming, difficult, and error-prone manual analysis of long-term EEG recordings. This paper presents a new method to detect SWD, with a low computational …
