title: Changes in cognition following mild stroke.
abstract: The objective of the study was to determine how performance on cognitive assessments administered in the subacute phase of mild stroke change or remain stable over time. A prospective longitudinal cohort pilot study was used to assess the cognitive status of participants with mild stroke (n = 20) at two time points: (1) within 3 weeks post-discharge from the acute care setting following mild stroke, and (2) approximately 6 months post-mild stroke. Participants were given a battery of cognitive assessments at both time points that included the following measures: (1) Short Blessed Test, (2) California Verbal Learning Test (CVLT), (3) Connor's Continuous Performance Task (CPT), and (4) The Delis-Kaplan Executive Function System (DKEFS) Trail Making subtest. The only significant differences between the test administrations was on the CVLT Short Delay Free Recall (p = .027) and Long Delay Free Recall (p = .002) which was likely due to practice effects associated with this measure. The results of the study show that performance on standardised cognitive testing in the early phases of mild stroke remained stable over a 6 month period. These results help justify the necessity and ability to assess cognition immediately post-mild stroke in order to make accurate and appropriate rehabilitation recommendations.
