Abstract:
The purpose of this study was to distinguish between patients
with moderate and severe dementia of the Alzheimer type (DAT) using
the Consortium to Establish a Registry for Alzheimer's Disease
(CERAD) Neuropsychological Assessment Battery. Patients from a
southeastern psychiatric setting with either moderate or severe DAT
were administered the CERAD. Results revealed that moderate DAT
patients were more impaired than severe DAT patients on measures of
verbal fluency, immediate and delayed memory, recognition memory,
percent retention, and constructional praxis recognition. Moderate
and severe DAT patients did not differ in their performance on
confrontational naming. These results lend support to the findings
of Welsh et al. (1992) in that, in addition to memory measures,
nonmemory measures can also be used to discriminate between
moderate and severe DAT patients. 62A
