SD, standard deviation; WASI-V, Weschler Abbreviated Scale of Intelligence Vocabulary (Wechsler, 1999). A maximum score of 80 can be obtained, with a higher score indicating better performance.

A maximum score of 30 can be obtained, with a higher score indicating better performance. GDS, Geriatric Depression Scale. A maximum score of 30 can be obtained, with a higher score indicating greater symptoms of depression.
