Differential characteristics of the aging process and the vascular cognitive impairment in the organization of memory retrieval

VCI patients show a reduced efficiency of retrieval and recall organization while, age-associated cognitive changes consist of a modification of the serial position effects. In particular, VCI patients, as distinct from same-age normal cases, can perform an only partial utilization of the inherent structure of the memory task with a very limited efficiency of relearning which is not sufficiently supported by the facilitating factors due to task repetition.
