The BNA-Long Form consists of 24 subtests within separate domains: Attention, Memory, Language, Visuospatial Function, Executive Function, and Praxis. The BNA-Short Form consists of 13 subtests within the domains of Attention, Memory, Naming, Visuospatial Function and Executive Function. In addition to individual domain indices, a Grand Total score was calculated for both BNA versions.<\/jats:p><\/jats:sec><jats:sec id=\"S0317167100003930_abs2\"><jats:title>Objective:<\/jats:title><jats:p>To standardize the administration and scoring and validate the BNA for detection of dementia.<\/jats:p><\/jats:sec><jats:sec id=\"S0317167100003930_abs3\"><jats:title>Methods:<\/jats:title><jats:p>Standardized normative data were obtained on 115 healthy subjects ranging in age from 50 to 95.

Grand Total indices of both BNA versions showed significant, positive correlations with the MMSE. Both BNA versions had superior sensitivity to dementia relative to the MMSE (.93 versus .79).
