BACKGROUND The term, "triphasic wave" originally described an EEG pattern believed to be a marker for a specific stage of hepatic coma. For 4 decades, the diagnostic and prognostic specificity of the pattern remains controversial. Its pathophysiology also continues to be elusive. METHODS EEG recordings were obtained in three patients known or suspected to have primary generalized epilepsy. In...

Simultaneous video-EEG monitoring has allowed pseudoseizures to be effectively diagnosed. Discussing the results of the monitoring with the patient is the 1st step in treatment. We outline a protocol for presenting the diagnosis of pseudoseizure with the goal of conveying to the patient the importance of knowing the nonepileptic nature of the spells and the need for psychiatric follow-up. The p...

PURPOSE Video ambulatory EEG (V-AEEG) is a new technique which could add increased capacity for long term EEG monitoring to overstretched inpatient video telemetry (IPVT) services. We compare V-AEEG and IPVT for diagnostic efficacy, recording quality, patient acceptability and technologist time required. METHODS Forty-one V-AEEG and 64 IPVT adult patients were included. Patients were investig...

Abstract Recent advances in computer technology have made it possible to perform prolonged digital continuous video EEG monitoring of many critically ill patients simultaneously. Recent studies using continuous EEG monitoring (cEEG) have found that these patients, especially those with coma, acute brain injury, or prior clinical seizures, often have nonconvulsive seizures (NCSz), and that these...
