- Recall address (42 West Street) at end (1 point)

How the result is read
The result is shown as AMT, out of a maximum of 10.
The calculator reads each total as follows. Where a single answer changes the reading (for example sex, age or one extreme value), the working calculator says so.
| Total | Band | What the calculator says |
|---|---|---|
| 0 to 6 | Impairment likely | Exclude delirium (4AT); investigate reversible causes; consider memory clinic. ≤ 6 suggests cognitive impairment or delirium. |
| 7 | Borderline | Repeat; consider 6-CIT / fuller assessment. |
| 8 to 10 | Normal | No gross cognitive impairment. 8–10 normal. |
