Moca test sits at the center of this dementia and brain health question.
MoCA test scores measure cognitive function on a 30-point scale, with higher scores indicating better cognitive health. A score of 26 or higher typically indicates normal cognitive function, while scores between 18 and 25 suggest mild cognitive impairment (MCI), and scores below 18 signal the need for further evaluation and safety assessment. For example, if your mother scores a 24 on the MoCA, this falls into the mild cognitive impairment range, which means her cognitive abilities show some decline compared to healthy aging, but she is not necessarily in the early stages of dementia. The Montreal Cognitive Assessment (MoCA) is a brief screening tool that takes about 10 minutes to complete and evaluates multiple cognitive domains including memory, attention, language, and visuospatial skills.
It’s important to understand that while the MoCA can help identify cognitive changes, it is a screening tool only—not a diagnostic instrument. A low score indicates that further evaluation is needed, but the MoCA alone cannot diagnose dementia or any specific condition. As a caregiver, understanding what your loved one’s MoCA score means is the first step toward appropriate next actions. If you notice declining memory or cognitive abilities, talking with your loved one’s doctor about getting tested can help identify what’s happening and what support may be needed.

What Does the MoCA Test Measure and How Is It Scored?
The MoCA evaluates five major cognitive areas: memory (the ability to recall information), attention (the ability to focus and concentrate), language (speaking, understanding, and naming), visuospatial skills (understanding where objects are in space), and executive function (planning and problem-solving). The test includes tasks like repeating words, drawing a clock, copying a cube, and naming animals—activities that seem simple but actually reveal how well someone’s brain is functioning across these different domains. The scoring is straightforward: a perfect score is 30 points, with each task worth a specific number of points.
After administration, the total is calculated, and if the patient has 12 or fewer years of formal education, 1 point is added to the raw score to account for educational differences. This adjustment is important because education level can affect cognitive test performance. For instance, someone with an 8th-grade education who scores 25 on the MoCA would have 1 point added, bringing their adjusted score to 26, which falls into the normal range rather than the MCI range.
Understanding MoCA Score Ranges and What They Mean
The interpretation of MoCA scores follows a clear framework. A score of 26–30 indicates normal cognitive function, which is what most people without memory problems achieve. The average score for cognitively healthy individuals is 27.4 points. A score of 18–25 falls into the mild cognitive impairment (MCI) category, with the average MCI score being 22.1 points. A score of 10–17 indicates moderate cognitive impairment, and any score below 10 suggests severe cognitive impairment. It’s crucial to recognize that scores below 18 carry additional significance.
When someone scores below 18, healthcare providers recommend discussing safety assessment and reviewing medication management—topics that become critical for caregiver planning. For example, if your father scores 17, his doctor should evaluate whether he can safely drive, manage his medications independently, or handle financial decisions. This isn’t an automatic “no”—it’s a conversation starter about what supports he needs. The research backs up the MoCA’s ability to identify cognitive problems. Studies show that people with Alzheimer’s disease average a score of 16.2 points, and the test has 100% sensitivity for detecting Alzheimer’s disease when using a cutoff score of 26. This means if someone has Alzheimer’s, the MoCA will almost certainly catch it. The test also shows 90% sensitivity for detecting mild cognitive impairment, making it a reliable screening tool—though again, not a diagnostic tool.
What Average Scores Tell Us About Cognitive Health
Understanding what “normal” looks like helps put individual scores in context. The average cognitively healthy person scores 27.4 on the MoCA, which gives you a reference point for what typical aging looks like without significant cognitive decline. If your loved one scores 28, they’re performing at an above-average level and likely have no cognitive concerns at this time. If they score 25, they’re slightly below the healthy average but not in the MCI range, which might warrant monitoring but doesn’t necessarily indicate a problem.
Comparing group averages reveals how cognitive impairment progresses. The gap between healthy cognition (27.4) and mild cognitive impairment (22.1) is about 5 points—a noticeable decline. The gap between MCI (22.1) and Alzheimer’s disease (16.2) is another 6 points. This progression underscores why catching cognitive change early matters. Someone with a score of 23 is closer to the Alzheimer’s average than to the healthy average, signaling that further evaluation should happen sooner rather than later.
Preparing for the Test and What Happens During Administration
The MoCA is administered by a qualified healthcare professional—typically a doctor, nurse practitioner, or trained cognitive specialist. The appointment usually lasts 10–15 minutes total, including time for explanation and discussion. Your loved one should plan to be alert and well-rested on test day. Caffeine is fine, but being exhausted or acutely ill can affect performance. If your mother has an early appointment and tends to be groggy in the morning, ask to schedule it later in the day when she’s more alert.
During the test, the healthcare provider will ask your loved one to perform various tasks: recall words that were read aloud at the beginning, name pictures of animals, copy geometric shapes, draw a clock, and answer questions about the current date and place. Some tasks are timed, and the whole process is straightforward—there are no “trick” questions. The environment should be quiet and free from distractions. If your loved one is nervous or anxious, this can actually lower their score, so encouraging a calm approach helps ensure the results are accurate. After the test, the clinician will score it and discuss the results. This is when you, as a caregiver, should ask questions about what the score means specifically for your loved one’s situation, whether further testing is recommended, and what changes you might expect.
Factors That Can Lower Test Scores Without Indicating True Cognitive Decline
One of the most important things caregivers need to understand is that several factors can lower MoCA scores without reflecting actual cognitive problems. Fatigue, anxiety, hearing loss, and language barriers are common culprits. If your father has untreated hearing loss and misses some of the test questions because he couldn’t hear them clearly, his score will be artificially low. Similarly, if English is not his first language, some language-based tasks might be harder, even though his cognitive function is fine. Socioeconomic factors can also affect performance.
Someone who has had limited access to education or healthcare throughout life may score lower on the MoCA in ways that don’t reflect progressive cognitive decline. This is why the educational adjustment exists—to level the playing field somewhat. However, it’s also why a single MoCA score should never be the sole basis for any diagnosis or major decision. Anxiety deserves special mention because it’s common during cognitive testing. Your loved one may worry they’ll “fail” the test, and that anxiety can make it harder to concentrate and remember things, leading to a lower score than their actual abilities warrant. Having a calm, supportive environment and reassuring them that the test is just a screening tool—not a test they can pass or fail—can help reduce anxiety and lead to more accurate results.
What to Do With Your Loved One’s MoCA Results
Once the MoCA has been administered and scored, results should be printed and shared with your loved one’s physician for professional evaluation and interpretation. This is not something to interpret on your own, even with the information in this article. A qualified healthcare professional needs to consider the MoCA score in the context of your loved one’s medical history, current symptoms, medications, and any other health issues they may have.
For example, someone with a recent stroke, a B-12 deficiency, or thyroid disease might score lower on the MoCA, and treating the underlying condition could improve the score. If the score indicates cognitive impairment (below 18), the doctor will typically recommend further evaluation, which may include neuropsychological testing (a more detailed cognitive assessment), brain imaging like an MRI or CT scan, and blood work to check for treatable conditions. These additional tests help determine whether cognitive changes are due to dementia, medication side effects, thyroid problems, vitamin deficiencies, or other reversible causes. Caregiver support information should also be provided at this point, regardless of the underlying cause.
Taking Action After Cognitive Decline Is Identified
If your loved one’s MoCA score suggests cognitive decline, the next step is working with their healthcare team to understand the cause and develop a plan. The score itself doesn’t tell you whether someone has Alzheimer’s disease, vascular dementia, Lewy body dementia, or another condition—or whether the decline is from a reversible cause like depression or medication side effects. That’s why professional diagnosis through comprehensive evaluation is essential.
Once a diagnosis is established, if dementia is confirmed, planning becomes important. This is when caregivers often benefit most from support groups, educational resources, and conversations about future care, safety modifications, legal documents, and financial planning. The MoCA score, while just a number, can be a wake-up call that prompts families to have these conversations earlier, when your loved one may still be able to participate in planning and decision-making.
Conclusion
MoCA test scores explained in simple terms: 26–30 is normal, 18–25 indicates mild cognitive impairment, 10–17 indicates moderate impairment, and below 10 indicates severe impairment. As a caregiver, understanding these ranges helps you know whether further evaluation is needed and what questions to ask your loved one’s doctor. Remember that the MoCA is a screening tool, not a diagnosis, and should always be interpreted by a qualified healthcare professional in the context of your loved one’s complete medical picture.
If your loved one has had an MoCA test or you’re considering whether one would be helpful, use the score as a starting point for conversation with their healthcare provider. Ask what the score means for your loved one specifically, what further evaluation or monitoring might be recommended, and what support is available for you as a caregiver. Catching cognitive changes early—and understanding what they mean—gives you and your loved one more time to plan, adapt, and maintain quality of life together.
