Abstract

Delirium is a common disorder in hospitalized elderly patients. It is a complex neuropsychiatric syndrome with disturbance of consciousness, attention, cognition, and perception. Treatment is based on identification and correction of the underlying cause together with symptomatic treatment. Decreased cholinergic activity is often considered to be one of the essential features in the pathophysiology of delirium. Therefore, correction of this cholinergic deficiency appears to be a promising approach. In this article we describe the pathophysiology of delirium, the pharmacological properties of rivastigmine, and the use of rivastigmine in the prevention and symptomatic treatment of delirium.
