"The Castle of Remembrance": New insights from a cognitive training programme for autobiographical memory in...

Autobiographical memory deficits are prominent from the early stages of Alzheimer's disease (AD) and result in a loss of personal identity. Nevertheless, standardised methods of autobiographical memory stimulation for the neuropsychological rehabilitation of patients with AD remain underdeveloped. Our aim was to evaluate the impact of a new cognitive training programme for autobiographical memory (REMau) on both the episodic and semantic components of autobiographical memory performance across lifetime periods, as well as on mood. Pre/post evaluations were conducted on two groups of patients with early to moderate AD, assigned to one of two different training activities: either the REMau or a cognitive training programme focused on collective semantic memory. Statistical comparisons showed significant improvement of episodic and semantic autobiographical memory performance in the REMau group, which was more pronounced for the semantic component, as well as improved mood. By contrast, deleterious pre/post differences were observed in the other group. Most interestingly, this study showed that the REMau programme boosted autobiographical memory from the reminiscence bump period, which is considered crucial for the construction and maintenance of personal identity. We discuss the theoretical and practical implications of these results for the reduction of autobiographical memory deficits in AD.
