New data highlights the importance of understanding baseline cognitive assessment benchmarks. According to research published in the Journal of the American Geriatrics Society, approximately 90 percent of healthy adults aged 65-80 score 26 or higher on the Montreal Cognitive Assessment—well within the normal cognition range.
The MoCA’s scoring distribution demonstrates that perfect and near-perfect scores are relatively common among cognitively intact individuals. Scores of 26-30 indicate normal cognition, while scores between 18-25 suggest mild cognitive impairment, and those below 10 indicate severe impairment. This statistical perspective underscores that the assessment functions as a dementia screening tool rather than an intelligence measure.
Understanding these baseline benchmarks helps patients and healthcare providers interpret results accurately, avoiding misinterpretation of normal cognitive function as exceptional ability. Read the full article on GMJ Newsroom.
