Standardized Italian norms for the Freedman version of the Clock Drawing Test have been established, requiring age adjustments for specific conditions.
Standardized norms for the Freedman version of the CDT were collected in a large sample of healthy individuals. No adjustments were required for scores on the free-drawn condition, whereas raw scores on the predrawn and examiner-drawn conditions and the total score needed adjustments to account for age effects. The availability of standardized norms for this version of the CDT could increase the use of this comprehensive tool in the detection of dementia.
