Abstract:
Here we report an investigation on the serial position effect (SPE) in elderly patients with early dementia due to different etiologies. The Rey's 15 words test has been used to evaluate whether different types of dementia show different patterns of immediate and delayed recall and of learning process. Ninety-four patients were recruited from the Geriatric Clinic of Padua. We evaluated the primacy effect (PE), the recency effect (RE) and the learning process within the sample. Our results indicate that different etiologies have different patterns of anterograde memory impairment.
