Cognitive tests (MMSE vs MoCA) for tracking Alzheimer's
Key points
- Both MMSE and MoCA are reliable for tracking cognitive change in Alzheimer's, with moderate correlation over time.
- The MoCA is more sensitive to early MCI, while the MMSE is widely used across all stages.
- A single score is not a diagnosis; always interpret in context of daily function and other causes.
- Track scores over time (every 6–12 months) to see trends, not just one number.
- Nearly 40% of people may have stable MMSE scores over two years, so functional decline is equally important.
- Cultural and educational factors affect scores; ask about adjusted norms.
General caregiving information, not medical advice. Check medications and major care changes with your clinician.
Step-by-step
Ask the clinician which test they use and why. In a research clinic, both MMSE and MoCA may be given. Ask: 'Which test are you using today, and what does a typical score look like for someone at my loved one's stage?' This helps you understand the baseline.
Request a copy of the test results after each visit. Write down the date, the test name, and the total score. Keep a simple log—e.g., 'Jan 2025: MMSE 24, MoCA 18.' This gives you a concrete record to spot trends over months.
If the test is the MMSE, note that a score below 24 is often considered impaired, but this is not a hard cutoff. Ask the clinician: 'Given my loved one's education and background, what is a meaningful change for them?' For example, a drop of 3 points in one year may be significant.
If the test is the MoCA, understand that a score below 26 is often considered abnormal for MCI, but again, context matters. The MoCA includes a clock-drawing test—if your loved one struggles with that, it may point to executive function issues that affect planning and organizing tasks at home.
Track changes in daily function alongside test scores. Use a simple checklist: Can they still manage finances? Drive safely? Prepare meals? If test scores decline but daily function stays stable, the clinician may adjust the diagnosis (e.g., MCI vs. dementia).
Bring a list of your observations to the appointment. For example: 'In the last three months, Mom has gotten lost twice in the grocery store, and she forgot to pay a bill.' This gives the clinician real-world context for the test numbers.
If the test shows no change but you see decline at home, ask for a referral to a neuropsychologist for more detailed testing. The office-based tests are a snapshot; a full battery can detect subtle changes in specific domains like language or visuospatial skills.
Use the test results to plan care. For example, if the MoCA shows declining executive function, you might start simplifying daily routines, using visual cues like a whiteboard for schedules, or limiting driving. Discuss these changes with the clinician.
What not to do
Do not rely on a single test score to judge your loved one's abilities. A bad day due to fatigue, infection, or stress can lower the score. Instead, look at the trend over multiple visits and combine it with your daily observations.
Do not compare your loved one's score to a friend's or a neighbor's. The tests are not standardized for everyone—education, language, and cultural background affect scores. A score of 22 might be normal for someone with less education but concerning for a college graduate.
Do not assume a stable score means no progression. In the study mentioned, nearly 40% of people had unchanged MMSE scores over two years, yet their daily function may have declined. Always pair test scores with functional assessment.
Do not use the test as a 'pass/fail' for your loved one. The purpose is to track change, not to label them. If they score low, it does not mean they are 'failing'—it means the disease is progressing, and you need to adjust support.
Do not skip the appointment because the test feels stressful. Some people resist because they feel anxious or embarrassed. Explain that the test helps the doctor help them, and offer to sit with them during the test if allowed.
Practical tools
Score Tracking Sheet
Create a simple table with columns: Date, Test (MMSE/MoCA), Score, and Notes (e.g., 'tired today,' 'new medication'). Keep it in a notebook or a notes app. Bring it to every appointment. This turns abstract numbers into a clear story.
Phrases to Say to the Clinician
Use these exact questions: 'What does this score mean for daily life?' 'How does this compare to last time?' 'Is there a different test that might be more sensitive for my loved one's stage?' 'Should we consider a full neuropsychological evaluation?' These open up a conversation beyond the number.
Daily Function Checklist
Print or write a short list of 5–10 activities: managing medications, using the phone, preparing a meal, driving, handling finances, remembering appointments. Rate each as 'independent,' 'needs help,' or 'unable.' Update monthly. Compare this to test scores to see if they align.
Clock-Drawing Test Practice
If the MoCA includes a clock-drawing test, you can practice at home in a low-pressure way. Ask your loved one to draw a clock showing a specific time (e.g., 10 minutes past 11). Note if they can place the numbers correctly and draw the hands. This is a quick check of visuospatial and executive function.

Discuss with your clinician
Ask your doctor: 'Is the MoCA or MMSE more appropriate for my loved one's stage and background? Should we consider a different test like the SLUMS?'
Discuss: 'What is the expected rate of decline for someone at this stage? How do we interpret a stable score over a year?'
Inquire: 'Are there any medications or clinical trials that might slow decline, and how would these tests help us monitor that?'
Ask: 'Should we consider a full neuropsychological evaluation to get a more detailed picture of strengths and weaknesses?'
Discuss: 'How do we rule out reversible causes like vitamin deficiency or depression that could affect test scores?'
