Abstract: |
Delirium is a common problem in hospitalized patients and occurs for a variety of reasons. The main component of delirium is a state of disordered attention and arousal with altered cognition, such as impairment in thinking, memory, expressive or receptive language, visuospatial functioning, and executive functioning. It presents clinically in a variety of ways grouped into three categories: hyperactive, mixed, or hypoactive delirium. The etiology is usually multifactorial and a systematic approach to its diagnosis and management is required. The treatment is directed at the underlying cause and clinical symptoms, and should include pharmacological and nonpharmacological interventions. © 2014 Elsevier Inc. All rights reserved. |
