Topic: Brain imaging, connectivity and assessment
Objective The aim of this study was to evaluate the short-term stability and reliability of a brief computerized cognitive battery in established dementia types. Method Patients were administered the computerized battery twice with administrations approximately 2 hours apart, with intervening conventional neuropsychological tests. Patients were classified clinically, via consensus conference, as healthy controls (n = 23), mild cognitive impairment (n = 20), Alzheimer's disease (n = 52), dementia with Lewy Bodies ([DLB], n = 10), or frontotemporal dementia (n = 9). Results Minimal practice effects were evident across Cog-State test administrations. Small magnitude improvements were seen across all groups on a working memory task, and healthy controls showed a mild practice effect on the accuracy of associative learning. Conclusions In established dementia, administration of the CogState tasks appears sensitive to cognitive impairment in dementia. Repeat administration also provided acceptable stability and test-retest reliability with minimal practice effects at short test-retest intervals despite intervening cognitive challenges.

How this study scored 43/100
Published in a peer-reviewed journal. Scored zero for study design, effect reported and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 25 of the 58 points we could judge it on, which is 43 out of 100.
