Cognitive data

NPA comprised the formal Dutch translation of the CNS Vital Signs (CNS VS) computerized test battery (see Table S1 for a description of the seven tests that were used): Verbal Memory test (VEM), Visual Memory test (VIM), Symbol Digit Coding test (SDC), Shifting Attention test (SAT), Continuous Performance test (CPT), Stroop test I and Stroop test III. The local software application of CNS VS was used on a notebook computer. Three paper‐and‐pencil tests were administered: a Letter fluency task [40] and, from 2015 onwards, a Digit Span task (Forward and Backward) [41].
