Background:
Neuropsychological assessment plays a crucial role in the assessment of cognitive decline in older age. In India, there is a dearth of culturally appropriate standardized measure to assess cognitive functions in early dementia. The aim of the study was to examine clinical validity of NIMHANS Neuropsychological Battery for Elderly (NNB-E) in identifying early dementia.
Objectives:
To examine validity (discriminant and concurrent) of NIMHANS Neuropsychological Battery for Elderly (NNB-E).
Results:
Participants with AD showed significantly poorer performance on every test including memory and non-memory domains. However, tests of episodic and semantic memory were particularly sensitive in discriminating between normal and AD groups. Further scores on various subtests in the NNB-E were positively associated with scores on HMSE and negatively associated with Clinical Dementia Rating and Everyday Abilities Scale for India (EASI) scores.
Conclusions:
NNB-E was able to differentiate normal controls from AD patients, and it can therefore be an ecologically valid tool for Indian older adults.
