P3‐061: Familiarity‐based recognition in multidomain amnestic and nonamnestic cognitive impaired patients: A follow‐up retest

Familiarity-based recognition in the young, healthy elderly, mild cognitive impaired and Alzheimer's patients

This study investigates the possible existence of deficits in familiarity in five samples of participants spanning a broad range of ages and cognitive states. Five groups of 16 participants with a diagnosis of multi-domain cognitive impairment with a slight or no deficit in memory, 16 multi-domain amnestic, and 16 Alzheimer's disease patients were compared in a recognition test with equivalent samples of old and young healthy participants. In one of the tests, participants studied words extracted from a restricted set of letters of the alphabet that were later mixed with new words from a different set. The unconscious use of the fluency produced by the repeated use of the set of letters was…
