What MoCA score range indicates mild cognitive impairment?

• A. <18/30
• B. 18-25/30
• C. 26-30/30
• D. 10-17/30

Answer: (B)

On the Montreal Cognitive Assessment, mild cognitive impairment is indicated by a score in the mid-range below normal but not severely impaired. Specifically, scores between 18 and 25 out of 30 suggest mild cognitive impairment. This range reflects measurable cognitive difficulties—across domains like memory, attention, and executive function—while still allowing independence in daily activities, which is the hallmark that distinguishes MCI from dementia. A score of 26–30 is considered normal cognition, showing no substantial impairment, and scores below 18 point to more significant cognitive decline. The 18–25 band is used because it balances sensitivity and specificity for detecting subtle cognitive changes that warrant further evaluation. (Note: clinicians may adjust thresholds for education level, but the 18–25 range commonly flags MCI.)
