Possin KL, et al. - This cross-sectional study was performed to validate the 10-minute, tablet-based University of California, San Francisco (UCSF) Brain Health Assessment (BHA) for the purpose of a better detection, diagnosis and differential diagnoses of neurocognitive disorders. For detecting dementia and mild cognitive impairment (MCI), including MCI due to diverse etiologies, the BHA had excellent combined sensitivity and specificity. The subtests provided efficient, valid measures of neurocognition that were critical in making a differential diagnosis.
