Neuropsychiatric and cognitive profile of patients with DSM-IV delirium referred to an old age psychiatry consultation-liaison service

Abstract

Delirium is a complex neuropsychiatric syndrome with generalized cognitive impairment and disproportionate inattention. Sleep-wake cycle and motor-activity disturbances are also common. Comorbid dementia results in a similar phenomenological pattern but with greater cognitive impairment and later referral.
