Rey verbal learning test is a useful tool for differential diagnosis in the preclinical phase of @entity195 : comparison with mild XXXX and normal aging.

OBJECTIVE: To confirm that performance in verbal learning and memory test (Rey's Auditory Verbal Learning Test-RAVLT) is a helpful early neuropsychological marker of @entity303 of @entity195 (DAT). METHODS: RAVLT was administered as part of a more extensive neuropsychological battery at baseline evaluation in 116 unselected @entity1 referred by @entity2414 ( @entity2414 ). @entity1 were followed longitudinally for 2 years (average interval of 27.7+/-4 months). Seventy @entity1 were included in the study: 27 developed probable DAT; 17 were diagnosed as cognitively normal @entity1 and 26 were diagnosed with @entity73 ( @entity73 ). Remaining @entity1 abandoned or they did not meet the criteria for DAT, @entity73 or control. Performance on RAVLT at the baseline evaluation was compared between groups. RESULTS: @entity1 diagnosed two years later with probable DAT showed lower results, more frequently performed a score of zero at the delayed recall test (Trial 6) and had a percentage of forgetting (difference between Trials 5 and 6) higher than 75%. Score at delayed recall test and percentage of forgetting correlated with functional scales such as MMSE, Geriatric Depression Screening, Informant Questionnaire and Blessed's @entity303 Rating. CONCLUSIONS: RAVLT could help to identify those @entity1 with @entity2414 who would progress to DAT over a few years, and also to differentiate between the preclinical phase of @entity195 , mild @entity73 and normal aging. A score of zero at the delayed recall test or a percentage of forgetting > or =75% in @entity1 with @entity2414 is suggestive of probable DAT in the future.
