Delirium is a neuropsychiatric disorder characterised by severe cognitive impairment, but its specific neuropsychological profile has not yet been clearly delineated. Psychiatric symptoms of perceptual disturbance, such as hallucinations, illusions and misperceptions, are also common in delirium, suggesting that patients may have deficits in the cognitive systems underlying visual perception.
