Delirium is a cognitive disorder characterized by deficits in attention, arousal, consciousness, memory, orientation, perception, speech, and language. It is a common and serious problem among older persons at every healthcare interface.

This book will be of interest to professionals working in geriatrics, geriatric psychiatry, general psychiatry, or neurology, internists, intensive care unit specialists, and all who care for the elderly in hospitals or the community.
