A Pilot Program of Improved Methods for Community-Based Screening for Dementia

The authors examined the effectiveness of a voluntary memory impairment-screening program for community-dwelling older persons, assessing three factors: appropriateness of screening instrument, reliability of complaints of cognitive difficulties, and adherence to screening recommendations. Two cognitive screening instruments, the Mini-Mental State Exam (MMSE) and the Seven-Minute Screen (7MS) were compared in 59 participants. Twenty-nine percent showed signs of impairment on the 7MS. Results suggested that the 7MS and the MMSE may have different sensitivities and specificities for the detection of early dementia. Failure on the 7MS was not predicted by cognitive or functional complaints. The study identified and addressed factors affecting compliance with screening recommendations.
