Abstract

OBJECTIVE
Exploration of the questionable Alzheimer disease is important for accurate estimation of prevalence and incidence, understanding the natural history, and evaluation of treatment strategies for the Alzheimer disease. Subjects and
METHODS
We compared neuropsychological test performances among 14 nondemented controls, 14 elderly persons with questionable dementia of the Alzheimer type and 14 elderly persons with mild dementia of the Alzheimer type. The test performances analyzed were the digit span of the Korean Adult Wechsler Intelligence Scale, registration, short term memory and long term memory of the Cognitive Impairment Diagnosing Instrument, and paired association learning and logical memory of the Wechsler Memory Scale.
RESULTS
There was significant difference between questionable dementia of the Alzheimer type and controls in the long-term memory, short-term memory, immediate and delayed recalls of the logical memory, and easy association. But the subjects with questionable and mild dementia of the Alzheimer type scored similarly on all tests except the long-term memory.
CONCLUSION
These findings suggest that questionable Alzheimer disease may be the very early Alzheimer disease.
