The investigator sought to determine which neuropsychological tests are more likely to predict an individual’s cognitive decline (i.e., normal to mild cognitive impairment, mild cognitive impairment to Alzheimer’s disease) two years prior to conversion. A sample of non-decliners (N=109) compared to those who declined (N=24) in cognitive status (i.e., mild cognitive impairment or Alzheimer’s disease) with a mean age of 61.44 (SD=11.29) was examined. Results indicate the Rey-Osterrieth Complex Figure Test, Retention Trial (RCFT Retention; OR=0.93, p=0.005) is a significant predictor of conversion to MCI and the Buschke Delay (OR=0.54, p=0.017) is a significant predictor of conversion to AD. Due to group sample size difference, additional analyses were conducted utilizing a subsample of demographically matched non-decliners. Results indicate the RCFT Retention is a significant predictor of conversion to MCI (OR=0.94, p=0.019) and AD (OR=0.90, p=0.048) and Buschke Delay (OR=0.68, p=0.027) is a significant predictor of conversion to AD. Given the results of this dissertation, it may be important for clinicians/researchers to monitor these measures for the purpose of predicting cognitive decline.
