Intracortical electroencephalography in acute brain injury.

Objective: Continuous electroencephalography (EEG) is used in patients with neurological injury to detect electrographic seizures and clinically important changes in brain function. Scalp EEG has poor spatial resolution, is often contaminated by artifact, and frequently demonstrates activity that is suspicious for but not diagnostic of ictal activity. We hypothesized that bedside placement of an intracortical multicontact electrode would allow for improved monitoring of cortical potentials in critically ill neurological patients.

Autosomal dominant inheritance of centrotemporal sharp waves in rolandic epilepsy families.

Purpose: Centrotemporal sharp (CTS) waves, the electroencephalogram (EEG) hallmark of rolandic epilepsy, are found in approximately 4% of the childhood population. The inheritance of CTS is presumed autosomal dominant but this is controversial. Previous studies have varied considerably in methodology, especially in the control of bias and confounding.

Continuous EEG monitoring in the intensive care unit: technical and staffing considerations.

Continuous EEG monitoring in the intensive care unit (ICU) is superficially similar to that which occurs in the epilepsy monitoring unit, but it also presents unique technical challenges. ICU monitoring imposes an expectation of reliability on EEG recording equipment exceeding that which may be demanded by other settings; performance requirements may also differ. Reliable network connectivity between ICUs and other hospital locations is necessary, as is provision for off-site EEG review and display.

Continuous EEG monitoring in the intensive care unit.

It is now feasible and desirable to continuously monitor brain function with EEG in critically ill patients. Nonconvulsive seizures are more common than previously recognized and may contribute to impaired mental status and brain injury. Alerting stimuli commonly elicit periodic or ictal-appearing EEG patterns.
