A common cognitive profile in elderly fallers and in patients with Parkinson's disease: the prominence of impaired executive function and attention

Exp Aging Res. Oct-Dec 2006;32(4):411-29. doi: 10.1080/03610730600875817.

Abstract

The present study examined the cognitive profile of elderly fallers relative to healthy elderly controls and patients with Parkinson's disease (PD), a positive-control group, using a computerized battery. Fallers performed more poorly than controls on executive function, attention, and motor skills, but performed comparably on memory, information processing and the Mini-Mental State Examination. A similar profile was evident for PD patients. However, unlike PD patients, fallers were abnormally inconsistent in their reaction times. These findings indicate that elderly fallers may have a unique cognitive processing deficit (i.e., variability of response timing) and underscore the importance of executive function and attention as potential targets for fall risk screening and interventions.
