SLUMS and Mini-Cog are brief cognitive screening tests, but SLUMS samples more thinking skills and is designed to detect mild cognitive impairment and dementia, while Mini-Cog is shorter and focuses on recall and clock drawing. The better choice depends on whether the priority is a broader screen or a quick initial check. Neither test diagnoses dementia. An abnormal result means the person needs a fuller cognitive and medical evaluation.

What does each test measure?
SLUMS is a 30-point screen for adults age 60 and older. It includes 11 tasks covering orientation, delayed recall, calculation, animal naming, number span, clock drawing, shape recognition, and story recall. Saint Louis University describes it as a tool for identifying mild cognitive impairment and dementia and tracking change over time.
Saint Louis University's SLUMS information Mini-Cog uses only two components: remembering three words after a delay and completing a scored clock-drawing task. It generally takes about three minutes, making it practical when time is limited. The Alzheimer's Association's cognitive assessment information The central difference is breadth. SLUMS tests several cognitive abilities, while Mini-Cog provides a compact signal from memory and clock performance.
How are the scores interpreted?
Mini-Cog produces a score from 0 to 5. Recalled words contribute 0 to 3 points, and the clock contributes either 0 or 2 points. A score of 0 to 2 indicates a higher likelihood of clinically important cognitive impairment, according to the Mini-Cog scoring guidance. Mini-Cog scoring guidance SLUMS uses a 30-point scale, but its interpretation also considers education.
For people with a high-school education, scores of 27–30 are categorized as normal, 21–26 as mild neurocognitive disorder, and 1–20 as dementia. For people with less education, the listed SLUMS ranges are 25–30 for normal, 20–24 for mild neurocognitive disorder, and 1–19 for dementia. These categories are screening interpretations, not diagnoses. Saint Louis University's SLUMS form.
Why does clock drawing differ between the tests?
Both tests ask a person to draw a clock, but they use the result differently. SLUMS separately scores details such as placing the hour markers and showing the requested time.
Mini-Cog treats the clock as a simpler normal-or-abnormal item. That design keeps the test brief, but it provides less detail about the person's performance on the clock task. A person can therefore receive useful information from either test, but the results should not be compared as if their scores used the same scale or measured the same amount of cognitive ability.
Which test is more useful for mild cognitive concerns?
SLUMS is the more directly relevant option when the question involves possible mild cognitive impairment. Its design includes broader tasks, and its score categories distinguish mild neurocognitive disorder from the lower range associated with dementia. Mini-Cog's conventional cutoff was developed mainly to detect dementia.
Its developer states that evidence is insufficient to recommend Mini-Cog specifically as a screen for mild cognitive impairment. Mini-Cog instrument development information That does not make Mini-Cog unhelpful. A brief screen can identify people who need further assessment, especially when a longer set of tasks is impractical. The result should guide follow-up rather than settle the question.
What limitations should families and clinicians consider?
The person's language, education, and familiarity with the testing format can affect performance. Saint Louis University states that the original English SLUMS is not designed for people with limited English proficiency or for phone or virtual delivery. Mini-Cog also warns that unfamiliarity with an analog clock or limited literacy can reduce performance even when cognition is normal.
These limitations matter when interpreting a low score. Practical questions before screening include: If screening raises concern, arrange a fuller cognitive and medical examination. Neither SLUMS nor Mini-Cog alone can diagnose dementia.
- Is the person comfortable using the test language?
- Do the education-based SLUMS categories apply?
- Can the person see, hear, write, and follow the instructions?
- Will an abnormal result lead to a qualified professional evaluation?
Frequently Asked Questions
Can a person have a low screening score without dementia?
Yes. Both tests have limitations that can affect performance, and neither result diagnoses dementia. An abnormal screen requires further evaluation.
Do SLUMS and Mini-Cog use comparable scores?
No. SLUMS uses a 30-point, education-adjusted scale, while Mini-Cog uses a 0–5 scale based on word recall and clock performance.
