Clinical TrialA psychophysiological study of the development of delirium in coronary care units.
This is a longitudinal investigation of the psychophysiological mechanism for the development of delirium in coronary care units (CCUs). Ten patients satisfying DSM-III-R diagnostic criteria for delirium (group D) and 10 controls (group C) were drawn from patients admitted to CCU. ⋯ That is, from days 2 to 3, EEG findings showed an improvement in consciousness, and eye movement recordings manifested signs of anxiety and tension. These psychophysiological findings can be used to explain the transition from prodromal delirium to obvious delirium, and are supported by clinical features.
