| Abstract: | 56 nondemented elderly normal control (NC) Ss were studied at 3 consecutive annual administrations of the California Verbal Learning Test (CVLT). NC Ss with a positive family history for progressive dementia performed significantly worse than individuals with a negative family history for progressive dementia on several quantitative and qualitative indices of the CVLT and were more likely to undergo changes in diagnostic status over time (i.e., develop dementia of the Alzheimer type DAT]). Stepwise discriminant function analyses of critical CVLT indices of the NC Ss and of 25 patients with mild DAT classified 5 NC Ss as DAT patients 1–2 yrs prior to their eventual changes in diagnostic status. Results suggest that specific memory deficits may serve as preclinical cognitive markers for DAT, especially in individuals with risk factors for DAT such as a positive family history.
