Cognitive Assessment
Use when asked to administer, score, or explain a Cognitive Assessment — screening with the MMSE (Mini-Mental State Examination) — grounded in FormExamples/form-examples; distinct from confusion-assessment-method's acute-delirium focus.
Cognitive function screening using the MMSE (Mini-Mental State Examination) with functional impact assessment.
Scoring
Instrument: MMSE. Range 0–30.
- 24–30 — normal cognition.
- 18–23 — mild cognitive impairment.
- 0–17 — severe cognitive impairment.
What it covers
Demographics; referral information; orientation (time and place); registration; attention and calculation; recall; language; repetition and commands; visuospatial ability; and functional history.
Cognitive assessment vs. confusion assessment
The MMSE screens for chronic, stable cognitive impairment (dementia- spectrum); Confusion Assessment Method screens specifically for acute, fluctuating delirium. A patient can score low on the MMSE due to baseline dementia while also being screened separately for a superimposed acute delirium — the two questions and instruments aren't interchangeable.
Common pitfalls
- Using the MMSE score in isolation to diagnose dementia — it's a screening tool; a low score prompts further evaluation, not a standalone diagnosis.
- Not accounting for education level and language — MMSE performance is influenced by educational background and whether the test is administered in the patient's first language; scores need that context to interpret correctly.
- Confusing chronic cognitive impairment with acute confusion — see Confusion Assessment Method; conflating the two can miss a treatable acute cause (delirium) behind an apparent cognitive decline.
