Screening for cognitive impairment in the older adult.

Screening for cognitive impairment in the older adult is an often overlooked element of health promotion. Health care providers may assume that existing deficits will be apparent on routine medical encounters. Frequently, however, patients who are functionally impaired can present a convincing facade of normalcy. Objective screening is necessary to recognize decline. This article briefly reviews normal age-related changes in cognition and suggested screening tools as well as differential diagnoses, highlighting reversible aspects of impairment. Additionally, potential corrective measures are considered where appropriate. This evaluation will become even more significant as the geriatric population steadily increases.
