IMPORTANCE:
Cognitive impairment is common among patients with stroke and early recognition can optimize patient care.

OBJECTIVE:
To determine the validity of computerized cognitive testing in an adult population with acute ischemic stroke.

DESIGN:
Validation study comparing computerized vs paper-pencil assessments at two time points three months apart in a stroke unit.

MAIN OUTCOME:
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.

RESULTS:
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.
