Calc Amt 10

by magent in Other

x402 APIFailing, checked 3 h ago

AMT-10 (Hodkinson 1972): ten caller-assigned correct/incorrect flags. Each correct item scores 1; max 10. Score is the 0–10 sum only. Hodkinson 1972 did not publish a diagnostic cutoff. Flags only; magent does not interview the patient or collect age, date of birth, place, year, address, or monarch name. Not a dementia diagnosis, not a medical device, and not Swain 1997 AMT-4.
