Filter by:Electroencephalography (EEG) records electric activity of the brain using electrodes placed on the scalp. EEG is an important tool in the diagnostic work-up of patients with epilepsy. Specific types of sharp EEG discharges (epileptiform discharges) are associated with patients with epilepsy. The International Federation of Clinical Neurophysiology (IFCN) has recently published a set of six operational criteria for identifying epileptiform discharges. At least four criteria need to be present in order to classify a discharge as epileptiform. These criteria are largely based on expert opinion and have not been validated yet. It is not clear what the sensitivity and specificity of these criteria are, and which combination of these criteria are optimal. Each criterion is based on visual assessment. However, it is not known what the inter-rater agreement of these criteria are. EEG is traditionally inspected in sensor space, i.e. in the recording channels. Advances in signal analysis made possible reconstructing the electric currents in the regions of the brain generating them, and displaying the signals in the source space, instead of the sensor space. The objectives of this study are: to determine the inter-rater agreement of the IFCN criteria by visual analysis in sensor space, to determine the combination of criteria with the best accuracy (sensitivity and specificity) and assess the accuracy of evaluating the discharges in source space. The raters will analyze EEG recordings from 100 patients, from two groups: consecutive patients with epilepsy and consecutive patients with non-epileptic paroxysmal episodes. EEG was recorded during long-term video-EEG monitoring. As reference standard, the investigators used the evaluation of the patients´ habitual clinical episode. The performance of the criteria in sensor-space and the analysis in source space will be compared with the unrestricted expert scorings.
Developed by researchers from the Centers for Disease Control and Prevention (CDC), Project UPLIFT (Using Practice and Learning to Increase Favorable Thoughts) is a group telephone program designed to improve depression for people with epilepsy. Project UPLIFT uses evidence-based approaches of cognitive-behavioral therapy (CBT) and mindfulness-based cognitive therapy to help people manage and prevent symptoms of depression. For people with psychogenic non-epileptic seizures, there are few treatment options for depression that address the relationship between mood and seizures. There is evidence that mindfulness-based therapy and cognitive therapy are both effective for people with non-epileptic seizures, both in treating depression and reducing seizure frequency. In this study, Project UPLIFT will be offered to patients with psychogenic non-epileptic seizures. Project UPLIFT is facilitated by a trained clinician to groups of 4-8 patients over the telephone. The group will meet at a regular time, once a week, for 8 consecutive weeks. Participants will be assigned to one of two groups: an immediate-treatment or a waitlist control group which will begin Project UPLIFT 3 months after enrolling in the study.
