The diagnose standard of probable Alzheimer disease is the same as the standard of the National Institute of Neurological and Communicative Diseases and Stroke-Alzheimer Disease and Related Disorders Association.
Results
The results of the MCI discrimination rates are as follows: AVLT-II (51%) >AVLT-I (31%) > complex figure test-II (27%)…
