Primary outcome measure(s)
Time to Cognitive Worsening Within Cohorts as Measured by Cognitive Composite or Any of the Individual Composite Components — Baseline up to 7 years Cognitive composite may consist of International Daily Symbol Substitution Test-Medicines (iDSSTm ), International Shopping List Test (ISLT), Continuous Paired Associate Learning Test (CPAL).
Time to cognitive worsening is defined as a change in cognitive composite score or any of the individual composite components, from baseline at 2 consecutive visits.
