Abstract

Dementia is a syndrome characterized by progressive irreversible generalized cognitive decline that must include memory impairment (American Psychiatric Association [APA], 2000). Most symptoms of dementia begin in old age, with varied estimates of its prevalence due to different methodologies and analytic strategies employed, diverse types of assessments used, and disparate screening assessment cut-off points applied. The incidence of dementia is strongly correlated with age; a recent study suggests that 5% of adults over the age of 71 and perhaps 37.4% over 90 have dementia (Plassman, Langa, Fisher, et al., 2007).
