Recent high-profile claims about cognitive test performance have prompted medical professionals to clarify the distinction between screening tools and intelligence assessments. The Montreal Cognitive Assessment, a 30-point screening instrument developed in 2005, is specifically designed to detect signs of cognitive decline and dementia risk—not to measure intelligence levels.

A perfect score of 30/30 indicates normal brain function in healthy adults, which is the intended outcome for individuals without cognitive impairment. Medical experts emphasize that achieving a perfect score represents typical functioning rather than exceptional intellectual capacity.
Cognitive scientists stress that comprehensive intelligence testing requires specialized neuropsychological evaluations administered by trained professionals, distinct from brief screening protocols used in routine clinical practice. Read the full article on GMJ Newsroom.
