Background:Given the rate of the undiagnosed cases of dementia and the consequences of inappropriate care, understanding the factors that explain the use of medical and health care in dementia is a critical concern. Our objective was to identify the psychosocial and medical determinants of use of care in dementia.Methods:The study sample consisted of 308 participants: the persons with dementia (n = 99) selected from three French population-based cohorts (i.e. PAQUID, 3C, AMI), their family caregivers (primary, n = 96, and secondary, n = 51), and their general practitioners (n = 62). Use of care in dementia was considered according to two indicators: (1) recourse to secondary care, (2) number of community and health services used.Results:Multiple logistic models including sociodemographics and psychosocial variables revealed that the determinants of nonuse of care are similar both for the recourse to secondary care and for the number of community and health services used: lack of education and the contribution of the people with dementia to the decisions regarding their own care and dementia care services in the community area. In addition, satisfaction of the primary caregiver with the services used by his/her relative is associated with non-recourse to secondary care.Conclusions:Taken together, these results highlight the predominant role of psychosocial factors in the use of care in dementia and the importance of addressing this issue through an integrative approach including psychological, social, medical, and family dimensions.

Background Hearing loss in older adults is suspected to play a role in social isolation, depression, disability, lower quality of life, and risk of dementia. Such suspected associations still need to be consolidated with additional research. With a particularly long follow-up, this study assessed the relationship between hearing status and four major adverse health events: death, dementia, depression, and disability. Methods Prospective community-based study of 3,777 participants aged ≥65 followed up for 25 years. At baseline, 1,289 reported hearing problems and 2,290 reported no trouble. The risk of occurrence of the negative outcomes, including death, dementia, depressive symptoms, disability in activities of daily living (ADL), and instrumental ADL (IADL), was assessed with Cox proportional hazards models. Results Adjusting for numerous confounders, an increased risk of disability and dementia was found for participants reporting hearing problems. An increased risk of depression was found in men reporting hearing problems. In additional exploratory analyses, such associations were not found in those participants using hearing aids. Mortality was not associated with self-reported hearing loss. Conclusions Our study confirms the strong link between hearing status and the risk of disability, dementia, and depression. These results highlight the importance of assessing the consequences of treating hearing loss in elders in further studies.

Objectives To investigate the association between hearing loss, hearing aid use, and cognitive decline. Design Prospective population-based study. Setting Data gathered from the Personnes Agees QUID study, a cohort study begun in 1989–90. Participants Individuals aged 65 and older (N = 3,670). Measurements At baseline, hearing loss was determined using a questionnaire assessing self-perceived hearing loss; 137 subjects reported major hearing loss, 1,139 reported moderate problems (difficulty following the conversation when several persons talk at the same time or in a noisy background), and 2,394 reported no hearing trouble. Cognitive decline was measured using the Mini-Mental State Examination (MMSE), administered at follow-up visits over 25 years. Results Self-reported hearing loss was significantly associated with lower baseline MMSE score (β = −0.69, P < .001) and greater decline during the 25-year follow-up period (β = −0.04, P = .01) independent of age, sex, and education. A difference in the rate of change in MMSE score over the 25-year follow-up was observed between participants with hearing loss not using hearing aids and controls (β = −0.06, P < .001). In contrast, subjects with hearing loss using a hearing aid had no difference in cognitive decline (β = 0.07, P = .08) from controls. Conclusion Self-reported hearing loss is associated with accelerated cognitive decline in older adults; hearing aid use attenuates such decline.

Objectives Based on seemingly contradictory results in the existing literature, the objective of our study was to investigate whether older individuals suffering from chronic psychiatric disorders show a more rapid decline in cognitive performances than their non-psychiatric counterparts, or if the pattern of decline through older age is similar in both groups. Method A total of 820 older adults were selected from the Ageing Multidisciplinary Investigation (AMI) cohort study, which studies health-related issues of people over 65 years old living in rural areas. Among them, 30 suffer from chronic psychiatric disorders. Cognition was assessed with four neuropsychological tests: the Mini-Mental State Examination, the Digit Symbol Substitution Test, the Free and Cued Selective Reminding test and the Isaacs Set Test. Linear mixed models were used to compare the evolution of cognitive performances in the two groups between baseline and the four-year follow-up. Results Despite lower performances at baseline, the pattern of cognitive decline of the psychiatric group is similar to that of the control group. Conclusion As suggested by this study conducted in rural communities, community-dwelling people suffering from chronic psychiatric disorders should not be considered at greater risk of age-related accelerated cognitive decline than the non-psychiatric older population.

General practitioners (GPs) play a major role in the assessment of dementia but it is still unrecognized in primary care and its management is heterogeneous. Our objective is to describe the usual practices, and their determinants, of French GPs in this field.GPs' characteristics and practices when facing cognitive decline were collected through a telephone interview and a postal questionnaire. A descriptive analysis of all study variables was conducted. The study of quantitative explanatory variables was done by testing the equality of means and the choice of qualitative variables was based on the chi-square independence test or Fischer test.Hundred two GPs completed the study. GPs were in majority men, working in urban areas. Mean age was 54.4 years old. GPs' feeling of confidence and self-perception of follow-up of national recommendations is linked with their practices. Performing a clinical interview to assess cognitive impairment is linked with good communication skills. GPs feel less confident to give information about resources for dementia. The main reason alleged for underdiagnosis is the limited effectiveness of drug therapy.This study underlines the importance of GPs' feeling of confidence when managing cognitively impaired patients with dementia, and the need of increasing training in the field of dementia, which could improve the awareness of GPs about diagnosis and available resources.

Although ambulatory data collection techniques have been used in elderly populations, their feasibility and validity amongst elderly individuals with cognitive impairment and amongst couples remains unexplored. The main objective of this study is to examine the validity of Ecological Momentary Assessment (EMA) in elderly persons with or without cognitive impairment and their spouses. The sample included 58 retired farmers (mean 77.3 years, standard deviation [SD] 5.5) with or without cognitive impairment, recruited within a French cohort and 60 spouses (mean 73.4 years, SD 6.9). The presence of cognitive impairment determining by a panel of specialized neurologists permitted to define two groups: “The Cognitive Impairment Group” and “The Control Group”. EMA procedures consisted of repeated telephone interviews five times per day during four days for each spouse. Our results demonstrate the validity of EMA procedures through a 92.1% level of compliance, the absence of fatigue effects, and the lack of evidence for major reactivity to the methods. However, the specificity of our sample may explain the acceptance (42%) and response (75%) rates and may reduce the generalizability of the results to the general population of elderly individuals. Finally, the validation of such techniques may contribute to future research examining community-dwelling elderly individuals and their spouses. Copyright © 2013 John Wiley & Sons, Ltd.

Objective The objective of this study was to explore the associations of individual characteristics of both older people with dementia and family caregivers with the nutritional status of older people with dementia. Methods This cross-sectional study comprising 56 community-dwelling older persons with dementia and 56 family caregivers was conducted at home by a psychogerontologist working for a community gerontological center. Older people with dementia were assessed with Mini mental state examination, Instrumental Activities of Daily Living, Activities of Daily Living (ADL), and NeuroPsychiatric Inventory (NPI) and family caregivers with the Burden Interview (Zarit scale), the State-Trait Anxiety Inventory, the Center for Epidemiologic Studies Depression Scale, and the emotional impact measure of NPI. For both, nutritional status was evaluated using the Mini Nutritional Assessment (MNA). Results Among older people with dementia, 58.9% were at risk of malnutrition and 23.2% presented a poor nutritional status, and among the family caregivers, 32.1% and 5.4%, respectively. The MNA score of older people with dementia was strongly and inversely associated with the ADL score and was strongly and positively associated with the MNA score of family caregiver. These two factors significantly explained 32% of variation of MNA score of older people with dementia. Conclusions These findings confirm the value of investigating nutritional deficiencies in dementia within the caregiving dyad and suggest that the functional status of older people with dementia and the nutritional status of family caregivers should be carefully assessed.

Les relations entre alimentation et vieillissement cerebral sont complexes : en amont, une alimentation equilibree pourrait retarder le declin cognitif ; en aval, la demence retentit sur le statut nutritionnel de la personne âgee et de son aidant. L’alimentation apporte de nombreux nutriments qui pourraient ralentir le vieillissement cerebral. Les fruits et legumes sont riches en antioxydants (vitamines C et E, carotenoides, polyphenols) et vitamines du groupe B. Les poissons gras apportent des acides gras omega 3 a longue chaine indispensables pour le fonctionnement cerebral. Il est difficile d’attribuer specifiquement a un aliment ou un nutriment donne des effets protecteurs, car ils sont associes dans l’alimentation. Le regime dit « mediterraneen » est associe a un moindre risque de declin cognitif et de survenue d’une maladie d’Alzheimer. De nombreux facteurs physio-pathologiques, cognitifs, fonctionnels et psycho-comportementaux s’intriquent pour entrainer une alteration de l’etat nutritionnel de la personne atteinte de demence et de son aidant. Un mauvais etat nutritionnel de l’aide est associe a une symptomatologie depressive et a un fardeau eleve chez l’aidant. L’alteration de l’etat nutritionnel de la personne atteinte de demence doit etre consideree dans une approche multifactorielle des interactions entre l’aidant et l’aide autour de l’alimentation.

UNLABELLED The DMS 48 is a visual recognition memory test designed to detect memory changes in early Alzheimer's disease (AD). The aim of this study was to produce normative scores for this test and to assess its psychometric properties in the detection of AD by comparison with a widely used test of verbal episodic memory: the story recall task of the Wechsler memory scale. Methods. Data were collected in a sample of 1002 agricultural retirees, aged 65 years and over, included in the AMI study, a population-based cohort conducted in Southwestern France. The sample used to establish normative data included 750 non-demented elderly while the sample used to study the properties of the test to detect AD included 751 participants whose 34 with AD. To assess AD detection accuracy, DMS 48 was compared to the Wechsler story recall task. Results. Age, sex, and education were significantly associated with DMS 48 performances. Therefore, normative scores were calculated according to sex, age, and educational level, and described by percentiles. Regarding the test properties for AD detection, DMS 48 presented a good balance between sensitivity (Se) and specificity (Sp) both for immediate (Se=70.6%; Sp=79.6%) and delayed recall (Se=79.4%; Sp=72.9%). It also showed high negative predictive values, around 98.5% for both recalls. Detection values were roughly similar to that of Wechsler story recall task. CONCLUSION The DMS 48 seems to be as reliable as the Wechsler story recall task with similar detection properties. The DMS 48 is a test easy to administer in clinical situations and could be a helpful tool for AD screening.

The objective of this study is to compare cognitive decline of elderly people after entering an institution with that of elders living in the community with similar clinical conditions.The Personnes Agées QUID (PAQUID) cohort is a prospective population-based study which included, at baseline, 3777 community-dwelling people aged 65 years and older. Participants were followed-up for 22 years. Among those who were nondemented and living at home at baseline, 2 groups were compared: participants who entered a nursing home during study follow-up (n = 558) and those who remained living at home (n = 3117). Cognitive decline was assessed with Mini-Mental State Examination (MMSE), Benton visual retention test, and verbal fluency Isaacs Set Test.After controlling for numerous potential confounders, including baseline MMSE and instrumental activities of daily living scores, incident dementia, depressive symptoms, and chronic diseases, nursing home placement was significantly associated with a lower score on MMSE between the last visit before and after institutionalization (difference of 2.8 points, P.0001) and greater further cognitive decline after institutionalization (difference of 0.7 point per year, P.0001). Similar results were found for the Benton memory test. In a second series of analysis in which the persons who became demented over the study follow-up were excluded, the results remained unchanged.The present study suggests that institutionalized elderly people present a greater cognitive decline than persons remaining in the community. The reasons of that decline remain unclear and may be related to physical and psychological effects of institutionalization in elderly people.
