Intensive neurodiagnostic monitoring in psychiatry.
A series of technological advances have made it possible to closely monitor electrophysiological and behavioural manifestations of episodic clinical events over prolonged periods of time, with the ability to review the records at leisure or to submit them to computer analysis. The more promising techniques are time-locked video/EEG monitoring, cable telemetry, radiotelemetry, ambulatory cassette recording, intensive plasma anti-epileptic drug monitoring and continuous neuropsychological monitoring. The greatest promise of these techniques is for the diagnosis, research and management of epilepsy. For psychiatry, they offer additional help in the differential diagnosis of non-epileptic events from epilepsy, the most important of which are psychogenic seizures and episodes of aggression. This paper discusses the potential role of these techniques in the assessment of non-epileptic events and transient cognitive impairment in clinical psychiatry.
