The abbreviated form of the Brief Cognitive Battery in the diagnosis of dementia in Alzheimer's disease

Abstract The Brief Cognitive Battery (BCB) developed by our group for cognitive assessment of low educated individuals has also shown to be highly accurate in diagnosing dementia of individuals with medium or high levels of education, making it a useful tool for populations with heterogeneous educat...
