Detection of Interictal Epileptiform Discharges in Eeg
The diagnosis of epilepsy heavily depends on the detection of epileptiform discharges in interictal EEG, the EEG in between two seizures. By visual analysis a physician wants to detect these epileptiform discharges (spikes). Due to the wide variety of morphologies of epileptiform discharges, and their similarity to waves that are part of normal EEG or to artifacts, this detection is far from st...
متن کاملAutomatic Detection of Epileptiform Discharges in the EEG
The diagnosis of epilepsy generally includes a visual inspection of EEG recorded data by the Neurologist, with the purpose of checking the occurrence of transient waveforms called interictal epileptiform discharges. These waveforms have short duration (less than 100 ms), so the inspection process is usually time-consuming, particularly for ambulatory long-term EEG records. Therefore, an automat...
متن کاملfNIRS-EEG study of focal interictal epileptiform discharges.
Functional near-infrared spectroscopy (fNIRS) acquired with electroencephalography (EEG) is a relatively new non-invasive neuroimaging technique with potential for long term monitoring of the epileptic brain. Simultaneous EEG-fNIRS recording allows the spatio-temporal reconstruction of the hemodynamic response in terms of the concentration changes in oxy-hemoglobin (HbO) and deoxy-hemoglobin (H...
متن کاملA comparison between averaged spikes and individual visually-analyzed spikes in rolandic epileptiform discharges.
PURPOSE This study compared some morphological features of individual rolandic epileptiform discharges, used to obtain an averaged estimate, with those of the resulting estimate. METHOD Twenty-four averaged discharges from EEGs of 24 children showing rolandic spikes were compared with 480 individual discharges used in the averaging. The analysis was based on the occurrence of tangential dipol...
متن کاملThe influence of subclinical epileptiform EEG discharges on driving behaviour.
EEG and driving behaviour were monitored in 6 patients with subclinical focal and generalised epileptiform EEG discharges during 420 km of actual motorway driving in a suitably instrumented vehicle. Evidence of impaired driving performance during subclinical discharges was significant in 3 subjects (P less than 0.025 or less than 0.05) and was suggestive (P less than 0.1) in 1. The two patients...
