Regression-Based Normative Data for Independent and Cognitively Active Spanish Older Adults: Digit Span, Letters and Numbers, Trail Making Test and Symbol Digit Modalities Test.

We provide a friendly calculator for use in neuropsychological assessment in cognitively active Spanish people aged 55 or older.
