Reminiscence, or the process of thinking or telling about past experience, is thought to serve social, instrumental, and integrative functions. Our paper investigated these functions in Alzheimer's disease (AD). Twenty-six participants with a clinical diagnosis of probable mild AD and 28 control older adults filled in a French adaptation of the Reminiscence Functions Scale. Eight specific functions were assessed: death preparation, identity, problem-solving, teaching/informing, conversation, boredom reduction, bitterness revival, and intimacy maintenance. Both older adults and AD participants reported reminiscence about their past to prepare themselves for the idea of their own mortality. All participants also reported reminiscence "to reduce boredom" and "for something to do". However, reminiscence for death preparation and boredom reduction was reported more by AD participants than by older adults. In all participants, the death preparation function of reminiscence was significantly correlated with depression. Individuals with AD seem to reminiscence to cope with thoughts about their own mortality. This helps them to see that they have lived a full life and can therefore accept death more calmly. Individuals with AD also seem to cope with boredom by using reminiscence, probably as a tool to fill time or simply to create ease of conversation. [ABSTRACT FROM AUTHOR]

The 2008-2012 French Alzheimer plan has proposed measures to improve care for dementia patients in a more personalized and graduate approach owing to patients and caregivers needs. A key measure of the plan is the nationwide implementation of the MAIA (French acronym for Maison pour l'Autonomie et l'Intégration des malades d'Alzheimer). The main goal is to implement a process of integration through a network of partners involved in elderly care, assistance, or support. The MAIA model comprises tools and mechanisms necessary to improve the integrated care process; in particular, case management for elderly in complex situations. The purpose of this paper is to describe the main measures from the national plan that aim to improve care for dementia patients with an emphasis on the MAIA measure. We summarize initial results of case management activity in one MAIA in the South West of France and we present two vignettes of cases benefiting from case management in order to demonstrate the nature of intervention. The French Alzheimer plan has promoted several non-pharmacological strategies for dementia patients. Implementation of both integrated care and case management represent a challenging perspective for the elderly and health professionals. [ABSTRACT FROM AUTHOR]

BACKGROUND: Embodied conversational agents (ECA) are possible enablers of assistive technologies, in particular for older adults with cognitive impairment. Yet, dedicated interaction management techniques addressing the specificities of this public are needed. OBJECTIVES: We assess whether the interaction management framework of the LOUISE (Lovely User Interface for Servicing Elders) ECA has the potential to overcome the user interface constraints linked to cognitive impairment. METHODS: LOUISE supports key target-specific features: personalization; attention management; context reminders; image and video displays; a conversation manager for task-oriented interactions; and the foundations for a domain-specific XML-based language for task-oriented assistive scenarios. LOUISE's usability and acceptance were evaluated at the Broca geriatric hospital in Paris. with a group of 14 older adults with either mild cognitive impairment (MCI) or Alzheimer's disease (AD) through four simple but realistic assistive scenarios: drinking, taking medicine, measuring blood pressure and choosing the lunch menu. RESULTS: Most of our participants were able to interact with the ECA, succeeded in completing the proposed tasks and enjoyed our design. CONCLUSION: The field usability evaluation of LOUISE's interaction management framework suggests that this suite of interaction techniques can be effective in enabling interfaces for users with MCI or AD.

Postmortem neuropathological examination of the brain is essential in neurodegenerative diseases, to ensure accurate diagnosis, to obtain an a posteriori critical assessment of the adequacy of clinical care, and to validate new biomarkers, but is only rarely performed. The purpose of this study was to assess factors limiting brain donation, such as reluctance of physicians to seek donation consent, opposition from patients and families, and organizational constraints. We conducted a survey across French memory clinics and major neuropathological centers. Few postmortem examinations were performed annually, as less than one third of the centers had performed at least five autopsies, and 41% had performed none. The main limiting factor was the lack of donation requests made by physicians, as half of them never approach patients for brain donation. Reasons for not seeking donation consent often include discomfort broaching the subject and lack of awareness of the medical and scientific benefit of postmortems (77%), organizational constraints (61%), and overestimation of families' negative reaction (51%). Family refusals represented a second major obstacle, and were often caused by misconceptions. Identifying and addressing these biases early could help improve physicians' rate of making requests and the public's awareness about the importance of brain donation. [ABSTRACT FROM AUTHOR]

We selected twenty genes from the "Top Results" list on the AlzGene database website and assessed their association with risk of developing Alzheimer's disease (AD) in a large, genome-wide association study (using 526 SNPs from 2,032 AD cases and 5,328 controls) performed in France. The APOE, CLU, PICALM, and CR1 loci were excluded, since they had already been extensively analyzed. Ten genes/loci (TFAM, SORL1, CHRNB2, SORCS1, DAPK1, MTHFR, GWA 14q32.13, BDNF, NEDD9, and CH25H) showed weak nominal association with AD risk, in line with previous studies. In the remaining ten genes/loci (TNK1, ACE, CST3, IL1B, hCG2039140, PRNP, GAB2, LOC651924, IL1A, and TF), no single nucleotide polymorphisms were associated in our dataset. Of the genes showing nominal association in our cohorts, TFAM and CHRNB2 appear particularly interesting and warrant further genetic and functional follow-up analyses. [ABSTRACT FROM AUTHOR]
