[Practical application of the CERAD test battery as a neuropsychological dementia screening test].

The CERAD neuropsychological test battery is becoming the standard measure for screening cognitive deficits associated with dementia. The seven subtests of the CERAD battery (Mini-Mental State Examination or MMSE, verbal fluency, Modified Boston Naming Test or MBNT, construction ability, learning of word lists, recall, and recognition), a short test of crystallized intelligence (vocabulary test or WST), and a simple test of visuo-motor tracking (number relation test-G or ZVT-G) were applied to 30 healthy control subjects, 49 depressed patients, and 98 mildly to severely demented patients. All subtests of the CERAD battery separated controls from mildly demented patients. Overall, depressed patients scored between controls and mildly demented patients. Score differences between depressed patients and mildly demented patients were significant for MMSE, learning and recall of the word list, verbal fluency, and MBNT. This paper contains a profile sheet for the CERAD battery developed according to published norms that allows rapid transformation of test results into a scaled graphical representation.
