Comparative validity of informant tools for assessing pre-stroke cognitive impairment.

ABSTRACT:

Objectives

Various informant-based questionnaires are used in clinical practice to screen for pre-stroke cognitive problems. However, there is no guidance on which tool should be preferred. We compared the validity of the two most commonly used informant-based tools.

We described criterion validity by evaluating associations between test scores and
