The graphical Mini-Cog was developed for rapid cognitive impairment screening in settings where a numerical score (0-5) is not required. The scoring system is the same as in the initial (Borson et al, 2000) proof-of-concept publication (see References). A pilot study conducted at the Cleveland Clinic (cited below) found that this version requires no training or prior exposure to administer and score with high accuracy. The standardized Mini-Cog requires brief training, such as you’ll find at actonalz.org, and should be used for most research and longitudinal, repeated clinical applications.
