Abstract
- Objectives To develop and validate a picture-based memory impairment screen ( PMIS) for the detection of dementia. Design Cross-sectional. Setting Outpatient clinics, Baby Memorial Hospital, Kozhikode city in the southern Indian state of Kerala. Participants Three hundred four community-residing adults aged 55 to 94 with a mean education level of 8 years; 65 were diagnosed with dementia. Measurements PMIS: a culture-fair picture-based cognitive screen designed to be administered by nonspecialists. Diagnostic accuracy estimates (sensitivity, specificity, positive and negative predictive power) of PMIS cut-scores in detecting dementia (range 0-8). Results PMIS scores were worse in participants with dementia (1.5) than in controls (7.7, P < .001). At the optimal cut-score of 5, PMIS had a sensitivity of 95.4% (95% confidence interval ( CI) = 90.3-100.0%) and a specificity of 99.2% (95% CI = 98.0-100.0%) for detecting dementia. In the 167 participants with <10 years of education, PMIS scores of five or less had a sensitivity of 97.8% (95% CI = 93.6-100.0%) and specificity of 99.2% (95% CI = 97.6-100.0%). The PMIS had better specificity than the Mini- Mental State Examination in detecting dementia, especially in older adults with low education. Conclusion The PMIS is a brief and reliable screen for dementia in elderly populations with variable literacy rates. [ABSTRACT FROM AUTHOR]
