How this service works
AMT-4 (Swain 1997): four caller-assigned flags for age, date of birth, place, and year. Each correct item scores 1; max 4. Impaired cognition is indicated when the score is less than 4 (0–3 impaired; 4 not impaired). Flags only; magent does not interview the patient or collect a date of birth, age, place name, or year. Not a dementia diagnosis and not a medical device. Not Hodkinson 1972 AMT-10.
Output
Returns an integer AMT-4 score (0–4) reflecting the sum of the four boolean flags, plus an impairment classification: a score of 0–3 indicates impaired cognition and a score of 4 indicates not impaired. Does not provide a dementia diagnosis and does not represent a medical device output.
Example use cases
ED triage cognitive screening
“I just screened a patient in the emergency department: they got their age right, their date of birth right, and the place right, but they couldn't name the current year. What's their AMT-4 score and does that count as impaired?”
Care home admission assessment
“We assessed a new resident — they correctly identified their age and the current year but were wrong about their date of birth and the place name. Can you compute their Swain AMT-4 score?”
Automated ward round documentation
“For this ward patient, all four AMT-4 items were answered correctly — age, date of birth, place, and year all right. Please calculate the AMT-4 score so I can record it in the notes.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/amt_4When to prefer
Use this endpoint when you need to programmatically score the Swain 1997 four-item AMT (AMT-4) and already have caller-assigned correctness flags for the four items. This is specifically the four-item abbreviated version (not the Hodkinson 1972 AMT-10), making it appropriate for rapid cognitive screening scenarios. Choose this over a full AMT-10 scorer when brevity is required or the clinical protocol specifies AMT-4.
Side effects
- Missing required query parameter (age_correct, dob_correct, place_correct, or year_correct) — likely returns 4xx error
- Non-boolean value passed for a flag — schema validation error
- Network timeout or server error returning 5xx
- Payment failure via x402 protocol resulting in 402 response
