Sums the seven MoCA domains (visuospatial/executive, naming, attention,
language, abstraction, delayed recall and orientation) to a total of 0-30. A
total below 26 indicates cognitive impairment. One point is conventionally
added for participants with 12 or fewer years of formal education (total
capped at 30); apply that adjustment to the orientation item (or the total)
before or after scoring as appropriate for your protocol.
Arguments
- items
Named numeric responses giving the points earned on each domain (e.g.
delayed_recall = 3,orientation = 6), or an unnamed vector in the instrument's item order.- ...
Passed to
scoreInstrument().
Value
A ClinicalScore with the total (0-30) and the impairment stratum (normal / mild / moderate-severe impairment).
Examples
scoreMoCA(stats::setNames(c(5, 3, 6, 3, 2, 5, 6),
getInstrument("moca")@items))
#> ClinicalScore [moca]
#> total = 30 (normal)
#> items used: 7, missing = error
