Abstract
The objective of the present study was to develop norms for the population older than 80years of age for the DTLA. We extend the original normative data to include 149 healthy, community-dwelling, French-speaking adults aged 80years old and older from the same countries. For the total score of the screening test, we calculated the 5th, 15th, 25th, and 50th percentiles for two education groups. The analyses allowed the identification of cutoff and alert scores based on education level. With the present study, solid normative data for the DTLA derived from the performance of 694 healthy, community-dwelling adults, and elderly people are now available to clinicians and researchers.
