MoCA Score Interpretation and Cutoff Scores — Questions and Answers
Question 1: What is the standard cutoff score indicating normal cognitive function on the MoCA?
- 20/30 or above
- 24/30 or above
- 26/30 or above (Correct answer)
- 28/30 or above
Correct answer: 26/30 or above
A score of 26/30 or above is considered within the normal range on the MoCA, as established in the original validation study by Nasreddine et al. (2005). Scores below 26 may indicate MCI or dementia and warrant further evaluation.
Question 2: For an examinee with 12 or fewer years of formal education, how should the MoCA total score be adjusted?
- Subtract 1 point as a penalty for lower cognitive reserve
- Add 1 point to the raw score to correct for educational bias (Correct answer)
- No adjustment is made — the raw score stands as administered
- Multiply the raw score by an education correction factor
Correct answer: Add 1 point to the raw score to correct for educational bias
Standard MoCA guidelines instruct the examiner to add 1 point to the total raw score for any examinee who has completed 12 or fewer years of formal education. This corrects for the well-documented effect of lower educational attainment on cognitive test performance independent of impairment.
Question 3: In the original MoCA validation study (Nasreddine et al., 2005), what sensitivity did the MoCA demonstrate for detecting Mild Cognitive Impairment at the 26/30 cutoff?
- Approximately 55%
- Approximately 72%
- Approximately 90% (Correct answer)
- 100%
Correct answer: Approximately 90%
The MoCA demonstrated approximately 90% sensitivity for detecting MCI in the original validation study, compared to only 18% sensitivity for the MMSE at its standard cutoff. This high sensitivity for MCI is one of the primary clinical advantages of the MoCA over older screening tools.
Question 4: What is the maximum possible total score on the MoCA?
- 25
- 28
- 30 (Correct answer)
- 35
Correct answer: 30
The MoCA has a total of 30 points distributed across eight domains: Visuospatial/Executive (5), Naming (3), Attention (6), Language (3), Abstraction (2), Delayed Recall (5), and Orientation (6). The Memory learning trials are unscored.
Question 5: A MoCA total score of 18–25 (after education correction) is most consistent with which level of cognitive status?
- Normal cognition
- Subjective cognitive decline only
- Mild impairment (often associated with mild dementia or moderate MCI) (Correct answer)
- Severe dementia
Correct answer: Mild impairment (often associated with mild dementia or moderate MCI)
MoCA scores of 18–25 are generally associated with mild cognitive impairment or mild dementia. Commonly cited bands are: ≥26 = normal; 18–25 = mild impairment; 10–17 = moderate impairment; <10 = severe impairment. These are guidelines, not diagnoses — clinical judgment and further evaluation are always required.
Question 6: Which of the following statements about MoCA score interpretation is CORRECT?
- A single MoCA score below 26 is sufficient to diagnose dementia
- The MoCA is a screening tool; abnormal scores require further comprehensive evaluation before diagnosis (Correct answer)
- MoCA scores are unaffected by cultural, linguistic, or educational background
- The MoCA can only be administered and interpreted by licensed neurologists
Correct answer: The MoCA is a screening tool; abnormal scores require further comprehensive evaluation before diagnosis
The MoCA is a screening tool, not a diagnostic instrument. A score below 26 identifies individuals who may have cognitive impairment and warrant comprehensive neuropsychological evaluation, but it does not constitute a diagnosis. Scores are also influenced by cultural, linguistic, and educational factors.
