The objectives of the present investigation were to determine whether subgroups of Cognitively-Impaired-Not-Demented (CIND) individuals with distinct neuropsychological profiles exist in two independent samples, and whether subgroup membership is related to diagnostic outcome over periods of 2 to 5 years. A series of cluster analyses was performed on ipsative factor z-scores derived from principal component analyses. Five subgroups were identified in the Base Sample (n = 461): Verbal… CONTINUE READING
