Patients in the ADRC clinical cohort are assessed annually within the ADRC clinic to monitor cognitive ability.  While most cognitive tests have been performed consistently over time, some tests have been implemented, discontinued, or modified over the years to incorporate changes to the NACC data collection process.  The figures below provide a graphical depiction of the neuropsychological tests conducted annually at the ADRC clinic. In each case, a small white line over the bars indicates that a test was changed or modified.  Hover over the different color bars for the corresponding test category. For more information on changes to particular tests please contact the DMSC using the information on the Contact Us page.
