Thornton 1 . EEG - correlated fMRI and Post - operative Outcome in Focal Epilepsy
Background: The main challenge in assessing patients with epilepsy for resective surgery is localising seizure onset. Frequently, identification of the irritative and seizure onset zones requires invasive EEG. EEG-correlated fMRI (EEG-fMRI) is a novel imaging technique which may provide localising information with regard to these regions. In patients with focal epilepsy, interictal epileptiform...
متن کاملPostoperative EEG and seizure outcome in temporal lobe epilepsy surgery.
OBJECTIVE To assess the prognostic value of scalp electroencephalogram (EEG) after epilepsy surgery, we investigated whether postoperative EEG abnormalities (interictal epileptiform discharges, IED; interictal slow activity, ISA) were associated with seizure outcome and other patient characteristics after resective surgery in patients with temporal lobe epilepsy (TLE). METHODS Sixty-two patie...
متن کاملNetwork analysis of EEG related functional MRI changes due to medication withdrawal in focal epilepsy
Anti-epileptic drugs (AEDs) have a global effect on the neurophysiology of the brain which is most likely reflected in functional brain activity recorded with EEG and fMRI. These effects may cause substantial inter-subject variability in studies where EEG correlated functional MRI (EEG-fMRI) is used to determine the epileptogenic zone in patients who are candidate for epilepsy surgery. In the p...
متن کاملEEG-triggered functional MRI in patients with pharmacoresistant epilepsy.
Functional magnetic resonance imaging (fMRI) triggered by scalp electroencephalography (EEG) recordings has become a promising new tool for noninvasive epileptic focus localization. Studies to date have shown that it can be used safely and that highly localized information can be obtained. So far, no reports using comprehensive clinical information and/or long-term follow-up after epilepsy surg...
متن کاملevaluation of partial epilepsy in iran: role of video-eeg, eeg, and mri with epilepsy protocol.
background: we evaluated the diagnostic value of electroencephalography (eeg), video-eeg monitoring (vem) and magnetic resonance imaging (mri) of the brain with epilepsy protocol in patients with complex partial epilepsy. methods: forty-two consecutive patients underwent complete neurological examination, eeg, and mri with a modified epilepsy protocol. a subset of these patients (n = 29) also u...
