Delirium, or acute confusional state, is a syndrome that presents as severe confusion and disorientation, developing with relatively rapid onset and fluctuating in intensity. It is a syndrome which occurs more frequently in people in their later years. Delirium represents an organically caused decline from a previously-attained baseline level of cognitive function. It is typified by fluctuating course, attentional deficits and generalized severe disorganization of behavior. It typically involves other cognitive deficits, changes in arousal, perceptual deficits, altered sleep-wake cycle, and psychotic features such as hallucinations and delusions. Delirium itself is not a disease, but rather a clinical syndrome, which result from an underlying disease, from medications administered during treatment of that disease in a critical phase, from a new problem with mentation or from varying combinations of two or more of these factors. It is a corollary of the criteria that a diagnosis of delirium cannot be made without a previous assessment, or knowledge, of the affected person's baseline level of cognitive function. In other words, a mentally disabled or demented person who is operating at their own baseline level of mental ability would be expected to appear delirious without a baseline mental functional status against which to compare.
