both sexes seen at the University of Nigeria Teaching Hospital, Enugu, were interviewed. The Mini Mental State Examination (MMSE) of Folstein, Folstein, and McHugh was used to assess cognitive function in each subject at a single instance. The results obtained were analyzed using SPSS version 11.3 (Chicago, IL). Consent was obtained from each person and
approval obtained from the hospitalfs ethics review board. Results: A cut.off score of .17 was obtained for normal cognitive function in this population using the MMSE. Minimum
score obtained was 12, while the maximum score was 30. A mean (2SD) of 24.84 (7.94) was obtained on analysis of the overall MMSE scores of the 135 individuals. Cognitive impairment was identified in 5.93% (8/135) of the subjects examined. These persons thus represent otherwise normal functional individuals with unrecognized mild cognitive impairment who may be at risk of developing overt dementia in future. Conclusion: The concept of mild cognitive impairment needs further large.scale studies in Nigerians with possible multi.centre participation to fully elucidate the scope of the problem. Strategies for the appropriate management of dementia need to be strengthened.
