SLUMS: Saint Louis University Mental Status Examination

What this assessment is

The Saint Louis University Mental Status Examination, or SLUMS, is an 11-question screen for possible cognitive impairment in older adults.

It samples orientation, memory, attention, calculation, language, executive ability, and visual-spatial performance. The result ranges from 0 to 30.

Higher scores indicate better performance.

SLUMS is a screening examination. It does not diagnose mild neurocognitive disorder, dementia, or a specific disease.

Who it was designed for

Saint Louis University describes SLUMS for adults aged 60 and older.

The original validation involved older veterans. The measure has since been studied in other groups, but its performance and suitable thresholds can change with the population.

Education is part of the published interpretation. The form uses one set of score ranges for people who completed high school and another for people who did not.

Language also matters. The official SLUMS guidance warns against using the original English form for people with limited English proficiency and provides separate translations.

How it is administered

A trained health or social-service professional asks the 11 questions and scores the responses during the session.

The assessment includes paper-based and drawing tasks. Official guidance says it is not suitable for telephone or virtual administration.

Hearing, vision, movement, speech, language, literacy, fatigue, pain, anxiety, and acute illness can affect performance. Record any barrier before interpreting the total.

Use the complete standard form. No verified general rule supports estimating a SLUMS score from missing questions.

What it measures

SLUMS samples several cognitive domains within one brief examination:

• orientation and attention
• immediate and delayed memory
• calculation
• language
• executive function
• visual-spatial ability

It gives a wider performance sample than a very short orientation test, but it is still not a full neuropsychological assessment.

The 6CIT is shorter and uses weighted errors. MoCA 8.1 also has a 30-point total but uses different tasks and an education-point adjustment.

Do not compare the numbers as if they were the same scale.

How scoring works

Points across the 11 questions add to a total from 0 to 30.

Higher totals indicate better performance on the tasks. The questions do not all carry the same number of points.

Use the scoring key for the current form. Do not assign equal points to every question, replace a missing response with zero, or create a partial total.

Record whether the person completed high school. That information selects the published interpretation ranges, but it does not change the arithmetic total.

How to interpret a SLUMS score

For people with a high-school education, the official form uses:

• 27 to 30: normal range
• 21 to 26: mild neurocognitive disorder range
• 1 to 20: dementia range

For people with less than a high-school education, it uses:

• 25 to 30: normal range
• 20 to 24: mild neurocognitive disorder range
• 1 to 19: dementia range

These are labels printed on a screening form. They do not make a diagnosis.

The current form starts its lowest ranges at 1 even though a total of 0 is mathematically possible. It does not provide a separate classification for 0. Do not silently invent one.

Review any low result with history, daily function, direct observation, informant evidence, health conditions, medicines, and further assessment.

What the score cannot tell you

SLUMS cannot identify the cause of low performance or distinguish a progressive disorder from delirium or another temporary problem.

It cannot establish decision-making capacity. It also cannot show that every cognitive area is intact when the total falls in a higher range.

Practice can affect repeated scores. Official guidance advises against repeating the test more than once a year in most situations unless rapid change is suspected.

Do not use a small score change as proof of improvement or decline without considering testing conditions and clinical context.

Evidence and limitations

The original SLUMS study compared the examination with the Mini-Mental State Examination in older veterans and reported stronger detection of mild impairment in that sample.

The sample was not every older adult. Age, education, language, culture, sensory function, and health can change performance.

The test also depends on standard in-person administration. A translated, remote, shortened, or modified form may not have the same score meaning.

Keep the language, education group, testing conditions, and form version with the result.
