| ≤ 6 | Abnormal: possible delirium or dementia |
Formula
One point per correct answer: age, time (nearest hour), address recall (given at start), year, name of place, recognition of two persons, date of birth, start year of WWI, present monarch/head of state, count backwards 20→1. Range 0–10.
Clinical pearls
- Threshold: <7 (≤6) abnormal, as used by the British Geriatrics Society AMTS sheet and the UK National Hip Fracture Database citing Hodkinson 1972; some validation studies prefer ≤7 or ≤8 for higher sensitivity.
- A low score does not distinguish delirium from dementia: use a delirium tool (e.g. 4AT) and collateral history.
- Adapt the historical and head-of-state questions to the local culture; deafness, dysphasia and language barriers falsely lower the score.
