MoCA vs MMSE vs Mini-Cog: which cognitive test, and what the scores mean
How the MoCA, MMSE and Mini-Cog work, typical cut-off scores, how long each takes, and their limits for people with less schooling or in other languages.
Quick answer
The MMSE (30 points, about 10 minutes) is the classic screen for dementia. The MoCA (30 points, about 10 to 15 minutes) adds executive and attention tasks and is more sensitive to mild cognitive impairment; 26 or above is the usual normal cut-off. The Mini-Cog (3-word recall plus a clock drawing, about 3 minutes) is a quick first check. All three are screening tools, not diagnoses.
What is a normal MoCA score?
A MoCA score of 26 to 30 is usually treated as normal, with one point added for people with 12 years of schooling or fewer. Lower scores suggest the need for a fuller assessment, not a diagnosis.
What is a normal MMSE score?
On the 30-point MMSE, scores of 24 or above are often treated as normal. Cut-offs vary with age, education and language, so results need a clinician's interpretation.
Side-by-side
| Mini-Cog | MMSE | MoCA | |
|---|---|---|---|
| Time | About 3 min | About 10 min | 10 to 15 min |
| Score | 0 to 5 | 0 to 30 | 0 to 30 |
| Covers | Recall, clock drawing | Orientation, recall, attention, language, copying | Adds executive function, attention, abstraction, delayed recall |
| Best at | Quick first check | Moderate dementia | Mild cognitive impairment |
| Licence | Free for clinical use | Copyrighted | Requires training and certification |
The limits of paper tests
- Education bias: people with little formal schooling can score low without any impairment.
- Language: translations do not always keep task difficulty the same.
- Ceiling effects: the MMSE can miss mild changes in well-educated people.
- Scoring by hand: clock drawing and figure copying vary between assessors.
What a digital assessment adds
A tablet-based assessment can pick the right version of each task for the person's schooling and language, time each answer, score drawings by written rules that show their working, and keep a record that can be compared over time. The clinician still reviews every score and makes the decision.
Frequently asked questions
The MoCA is designed to be given by a trained person. An online version needs a certified assessor to run and score it.
No. The MMSE is copyrighted and needs a licence. The Mini-Cog is free for clinical use.
The MoCA is more sensitive to MCI than the MMSE because it includes executive and attention tasks.
No. A low score is a reason for a full assessment by a doctor, who also checks for other causes.
