This test was administered to 70 cognitively normal participants, 62 participants with MCI and 64 participants with dementia. The 2nd edition of the Mini-Mental State Examination (MMSE-2), and the Montreal Cognitive Assessment (MoCA) were collected by certified psychologists. The ACST was performed by a clinician. The diagnosis was made according to DSM-V criteria by an experienced geriatric neurologist blinded to the application score. Content validity, test-retest reliability, interrater reliability, and correlations between application scores and MMSE-2 and MoCA scores were analyzed.
