Digital Cognitive Evaluation May Be More Reliable Than Montreal Cognitive Assessment
A clinical validation study published in Neurological Sciences and Neurosurgery suggests a new digital cognitive evaluation (Cognivue Clarity; Cognivue, Rochester, NY) had better test-retest reliability than the Montreal Cognitive Assessment (MoCA).
The results showed a statistically significant positive correlation between overall scores on the digital assessment and MoCA (r=0.38; P<.001). Test-retest reliability was higher with digital assessment (87.3%) compared with MoCA (73.1%) in participants who had no cognitive impairment at enrollment in the study.
“The study further demonstrates that Cognivue’s technology is the most reliable, non-biased, objective assessment of cognitive function decline,” said Fred Ma, MD, PhD, chief medical officer and senior vice president, Cognivue. “It further reinforces the findings of prior studies of the world’s first FDA-cleared computerized test of cognitive function and affirms the technology’s use in today’s evolving healthcare environments.”
The validation study involved 100 participants age 55 or more who completed 2 testing sessions 1 to 2 weeks apart using both Cognivue Clarity and MoCA. Correlation analyses were performed for overall scores on each neuropsychologic test and retest reliability was assessed via regression analyses.
Regression analyses of test-retest reliability demonstrated a statistically significant regression fit for each test (Cognivue Clarity: R2=0.439, r=0.663; MoCA: R2=0.378, r=0.615) with Cognivue Clarity revealing a tighter and more linear pattern than observed with MoCA.
