Lack of Correlation of WAIS Digit Span with Clox 1 and the Dementia Rating Scale in MCI

الملخص EN

Individuals with MCI declined in performance over 6 months in the Clock-drawing (Clox 1) and the WAIS Digit Span tests, but not in the Dementia Rating Scale (DRS).

Individual performance on Clox 1 and Digit Span did not correlate after 6 months.

Performance on the Digit Span Test also did not correlate with the DRS, but performance on Clox 1 correlated with the DRS.

Performance in Clox 1 was, therefore, not a predictor of performance in the Digit Span Test.

These findings support the use of a test battery containing the Digit Span test to detect and track cognitive decline in MCI.
