Abstract: Mild cognitive impairment (MCI) is characterized by a decline in cognition greater than expected given age and education level. Multiple screening instruments aim to detect subtle cognitive deficits associated with MCI. However, there are inconsistencies in the sensitivity and specificity of the instruments and tasks most reliable for identification of MCI. The present study aims to identify which tasks, task combinations and/or question items best discriminate MCI from healthy older adults (HOA). Ten participants with ages ranging from 55 to 82 were administered the Montreal Cognitive Assessment (MoCA), the Mini Mental State Examination (MMSE), and Arizona Battery for Communication Disorders (ABCD. Results revealed the MoCA accurately screened for MCI in three out of four participants. However, the MoCA misdiagnosed two HOA. While individuals with MCI consistently scored lower than HOA on the MMSE, all ten participants scored within normal limits. Analysis of the findings revealed the subtests from the ABCD with the greatest sensitivity for identifying MCI included: repetition, reading comprehension- sentences, mental status, story retelling-immediate, generative naming, and confrontation naming.
