Datasheet for the computing of the probability to be demented.
Feuille de calcul de la probabilité de démence.
The objective of this datasheet is to propose a screening instrument for dementia based on a reduced number of neuropsychological tests. Seven neuropsychological tests and the MMSE subscores were considered. The most discriminant combination of tests included the MMSE and the subscores "orientation to time" and "recall three objects," the Benton Visual Retention Test, and Isaacs' Set Test of verbal fluency.
To compute the probability to be demented, the following variables are needed:
If these tests are missing, the corresponding missing indicators (Immse, Ibvrt, Iist) must be set to 1.
Then, the probability to be demented is computed by using the formula:
Pr(demented) is > 0.005 then
the subject is screened positive.
