Bill Payment Subtest is Valid Screen For All-Cause Dementia

The Neuropsychological Assessment Battery Bill Payment subtest is a valid screening utility for all-cause dementia, a new study found. The study included 270 women and men who completed Bill Payment during outpatient neuropsychological evaluation. 71 patients were cognitively normal (CN), 160 patients had mild cognitive impairment (MCI), and 39 patients had dementia. Researchers found:

  • At a cutoff of 17, Bill Payment had strong sensitivity and specificity for dementia vs CN cases.
  • A cutoff of 15 distinguished dementia from MCI, whereas a cutoff of 16 distinguished dementia from functionality unimpaired cases (MCI + CN) with greater sensitivity and similar specificity.
  • Sensitivity attenuated in MCI vs CN cases.
  • Individuals who were independent in money management had higher scores vs assisted and dependent cases.
