How to Use This Calculator
- Enter scores for orientation, registration, attention, recall, and language tasks.
- Select the screening tool being used (MMSE, MoCA, or Mini-Cog) to apply correct scoring.
- Review the Total Score against the validated cut-off for the chosen instrument.
- Check domain-specific performance to identify whether impairment is in memory, attention, or language.
- Use the result to guide referral for full neuropsychological evaluation.
What each input means
- Word recall (0-3)
- Number of words correctly recalled from a 3-word list after a delay.
- Clock Drawing
- All numbers present and hands pointing to correct time.
- Orientation score (0-10)
- Time orientation (5) + place orientation (5). Knowing date, day, month, season, year, floor, city, state, country, hospital.
- Attention/calculation (0-5)
- Serial 7s (count back from 100 by 7) or spell WORLD backwards. Score 0-5.
- Language (0-3)
- Naming (2 items) + repetition (1 item). Score 0-3.
- Registration (0-3)
- Immediate word registration — number of words repeated correctly on first trial.
- Age
- Patient age. Dementia prevalence increases with age.
- Years of education
- Total years of formal education. Lower education may affect test performance.
What each result means
- Mini-Cog score (0-5)
- Total Mini-Cog: <= 2 = positive screen for cognitive impairment, >= 3 = negative screen.
- Positive screen (0/1)
- 1 = screen positive (impairment likely), 0 = screen negative.
- Estimated MMSE (0-30)
- Approximate MMSE equivalent: 24-30 normal, 19-23 mild, 10-18 moderate, 0-9 severe.
- Severity (0-3)
- 0 = Normal, 1 = Mild impairment, 2 = Moderate, 3 = Severe.
- Dementia probability
- Estimated probability of dementia given Mini-Cog results, age, and education.
- Recommend full assessment
- 1 = Full neuropsychological assessment recommended, 0 = routine monitoring sufficient.
- Functional cognitive age
- Estimated functional cognitive age based on screening results.
