OBJECTIVE: To review systematically studies investigating the convergent,
criterion, and predictive validity of multi-domain cognitive screening
instruments in the first four weeks after stroke.
DATA SOURCES: Electronic
databases (Pubmed, PsycINFO, CINAHL, Embase) were searched until June 2014.
REVIEW METHODS: Studies concerning screening for cognitive dysfunction in stroke
patients using multi-domain instruments, within four weeks postinfarct or
haemorrhagic stroke, using tests taking no longer than one hour. Convergent,
criterion, and predictive validity were examined. RESULTS:
A total of 51 studies
investigating 16 cognitive screening instruments were identified. None of the
instruments covered all of the most affected cognitive domains. Only one study
investigated the convergent validity of a multi-domain test during the (sub)acute
phase after stroke. A total of 15 studies examined the criterion validity of
cognitive measurements during the acute phase after stroke.
The Montreal
Cognitive Assessment and Higher Cortical Function Deficit Test had good criterion
validity. A total of 24 studies examined the predictive ability of multi-domain
cognitive instruments applied in the acute phase after stroke.
The Cognistat,
Montreal Cognitive Assessment, and Functional Independence Measure-cognitive
showed good predictive validity. The Mini-Mental State Examination is the most
widely used cognitive screening instrument, but shows insufficient criterion
validity. CONCLUSION: None of the existing instruments fulfils all criteria. The
Montreal Cognitive Assessment is the best candidate at present, provided items
measuring speed of information processing are added, and further studies
investigating the optimal cut-offs are conducted.
