Abstract

Delirium is acute onset & fluctuating disturbance in mental state that causes patient appear confused, disoriented or with difficulty to focus and with decline in cognitive function (memory, orientation, speech), circadian disturbance and behavior of patient either agitated or sleepy,in other words sudden confusion. Delirium, also known as acute confusional state, is an organically-caused decline from a previously baseline level of mental function that develops over a short period of time (hours to days). Delirium is not a disease itself, but a syndrome encompassing disturbances in attention, consciousness, and cognition. It may also involve other neurological deficits, like psychomotor disturbances (e.g. hyperactive, hypoactive, or mixed), impaired sleep-wake cycle, emotional disturbances, and perceptual disturbances (e.g. hallucinations and delusions).
