Cognitive impairment is common among patients with stroke and early recognition can optimize patient care.
To determine the validity of computerized cognitive testing in an adult population with acute ischemic stroke.
Validation study comparing computerized vs paper-pencil assessments at two time points three months apart in a stroke unit.
Correlation analyses between computerized (using CogState Brief Battery) and paper-pencil testing (using the Montreal Cognitive Assessment) both at study entry and follow-up visits.
We found moderate to strong significant correlations between the two instruments at study entry and follow-up sessions. Executive dysfunctions were the main cognitive changes. Test-retest correlations were strong.
CONCLUSION AND RELEVANCE
The CogState Brief Battery is a valid alternative for clinicians who wish to measure cognitive skills following acute ischemic stroke. Limitations of computerized testing are discussed.
