Abstract
Aim: to compare the two new executive function tests of the revised Cambridge Cognitive Examination (CAMCOG‐R), a bedside measure of cognitive function, with existing neuropsychological assessments of executive function in elderly stroke survivors. Methods: we assessed 83 stroke survivors at 1 and 3 months post‐stroke with the new CAMCOG‐R, the Weigl colour form sorting test and Raven's coloured progressive matrices. We assessed functional recovery with the Barthel index and depression with the self‐report 15‐item geriatric depression scale. We used descriptive statistics, Pearson correlation coefficients, paired t‐tests and principal axis factor analyses to interpret the data. Results: the new CAMCOG‐R executive functioning tests showed moderate correlation with the Weigl and Raven tests (PPPConclusion: although the new executive tests of the CAMCOG‐R compared reasonably well with the Weigl and Raven neuropsychological tests, the extra time taken to administer the CAMCOG‐R may not be justified. The new CAMCOG‐R executive function tests were vulnerable to the effects of depression. Finally, the executive function tests might have provided more of a global measure of cognitive function, raising doubts about their construct validity in our patient population.
