Yes. Someone can score in the normal MMSE range and still have memory problems.
The Mini-Mental State Examination (MMSE) is a brief screening test, not a complete measure of memory or a definitive diagnosis. In one study, 20 of 44 people with mild dementia—45%—scored normally, defined as 26 or higher. The result shows why ongoing concerns deserve attention even when a screening score looks reassuring.

What does the MMSE actually measure?
The mmse checks several mental abilities, including orientation, attention, memory, language, and constructional skills such as copying a design. Because it combines these areas into one total score, a person may perform well overall while having a specific memory weakness.
The Journal of Neurological Sciences study found that a normal score did not rule out mild dementia. A passing result means the screen did not detect enough difficulty to cross its cutoff; it does not prove that every memory function is intact.
Why can mild problems escape detection?
Brief screening tests can miss subtle problems. In 524 adults over 60 without dementia, MMSE sensitivity for mild cognitive impairment was only 4% at a cutoff of 25 and 45% at a cutoff of 28, according to research published in *Archives of Neurology*.University of California–San Diego research This pattern is consistent with a ceiling effect: people with milder difficulties may score near the top even when important changes exist. A person may also compensate successfully in familiar routines, making problems easier to notice through repeated mistakes than through a short test.
Could the problem be mild cognitive impairment?
Mild cognitive impairment, or MCI, means a person has more memory or thinking difficulty than expected for their age but can still manage normal daily activities. The National Institute on Aging explains that MCI may affect memory, language, judgment, or other thinking skills without causing the broader loss of independence seen in dementia.National Institute on Aging information about MCI A normal MMSE does not settle whether MCI is present. More detailed testing may reveal difficulty learning new information, recalling it later, concentrating, or solving problems even when the person handles ordinary tasks.
What can affect the score or cause memory symptoms?
The MMSE result can be influenced by education and literacy. A 2022 systematic review found that education biased MMSE scores and considered the instrument unreliable for people with low literacy.Systematic review in the *Journal of Geriatric Psychiatry and Neurology* Memory symptoms also do not automatically mean dementia.
Possible causes include medication effects, depression or anxiety, sleep problems, thyroid, kidney, or liver problems, and vitamin B12 deficiency. These possibilities make the person's health history and current symptoms as important as the score.
What should someone do after a normal result?
If memory concerns persist, ask for an evaluation that considers the whole pattern rather than the MMSE alone. The Cochrane review found that MMSE accuracy varies by cutoff and setting and concluded that the test should not be used by itself to confirm or exclude disease.Cochrane review of MMSE accuracy A clinician may review: The National Institute on Aging describes this broader approach to evaluating possible Alzheimer's disease and related symptoms.How Alzheimer's disease is diagnosed A normal MMSE can be useful information, but persistent changes still warrant a fuller assessment.
