The choice of 3-item recall as the memory test was based on research showing that this element in the Mini-Mental State Examination (MMSE) is the first to be impaired in early Alzheimer’s disease. in 2000 by combining a short memory test and an executive clock drawing test (CDT). The Mini-Cog (MC) is a short screening tool for clinically important cognitive impairment, originally developed by Borson et al. The MMC versions are promising and deserve further study as screening tools for cognitive impairment in larger and more fully characterized samples. Two alternate distractor tasks may successfully replace CDT in the Mini-Cog. In literate individuals, the acceptability and feasibility of CDT and both alternate distractors were similarly high (5/6). Both MMC versions correlated with DSRS in healthy adults and patients (rho 0.6-0.7, ). Literacy was associated with CDT (chi-square strength 0.9, ). Data were collected from 63 participants (, 67% nonliterate). Spearman’s rho, Mann-Whitney, and chi-square tests were used to evaluate group differences and associations between measures. Family members rated the acceptability and feasibility of the Mini-Cog versions using a 6-point scale and completed a proxy-rated cognitive staging tool, the Dementia Severity Rating Scale (DSRS).

We replaced the CDT with two tasks of everyday life: a serial subtraction task or a multistep performance task. Participants were adults (≥60 years) with no neurological diagnosis, with known cognitive impairment due to stroke, Parkinsonism, traumatic brain injury, or Alzheimer’s disease, and whose family members were able to read and write. We developed a modification of the Mini-Cog (MMC) for use with nonliterate and literate individuals. However, CDT requires at least basic literacy and cultural exposure to analog clocks, conditions not met in many population groups around the world.
The Mini-Cog, a rapid, valid, and reliable screening tool for cognitive impairment, consists of 3-word recall and an executive clock drawing test (CDT).
