RESUMO
The Community Screening Interview for Dementia (CSI 'D') was developed as a screening instrument for dementia for use in cross-cultural studies. It consists of two components, a cognitive test for non-literate and literate populations and an informant interview regarding performance in everyday living. The development of the CSI 'D', involving harmonization, translation, back translation and pilot testing, for use in five sites is described. The results demonstrate the adaptability and utility of the CSI 'D' in populations from very different socioeconomic backgrounds. The inclusion of informant data adds significantly to the performance of the CSI 'D' as a dementia screen. The combination of informant and cognitive scores in a discriminant score produces better sensitivity and specificity for dementia than cognitive scores alone. The informant score has a significant independent effect in predicting dementia.

Information on the clinical utility of neuropsychological tests in non-North-American samples is limited. We examined the diagnostic efficacy of the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) neuropsychological battery in Jamaican men and women age 65 and older. A total of 72 elders were diagnosed as normal and 12 were demented based on history, physical, and neurological examination. Independent of this medical examination, participants were tested with the CERAD battery. Normal controls scored significantly better than dementia patients on all tests in the CERAD battery. A discriminant function found that a combination of Word List Learning Sum Recall and Boston Naming Test correctly classified a total of 81% of the cases (83% of the dements and 81% of the normal controls). This study is the first to demonstrate the clinical utility of the CERAD neuropsychological battery in the differential diagnosis of memory disorders of the aged in a non-North-American sample.
