Neuropsychological test performance among healthy persons in northern India: development of normative data.

Accurate identification of neurocognitive impairment associated with HIV infection (and other CNS-involved conditions) is dependent upon utilization of appropriate normative neuropsychological test performance data from healthy individuals with a similar background, culture, and characteristics of the target individual or group to be tested. In India, regional differences in language, culture, and availability of resources can significantly affect performance on neuropsychological testing. This study developed age- and education-adjusted normative data for commonly used neuropsychological test scores for use in northern India.
