Abstract: Weight loss, together with psychological and behavioural symptoms and problems of mobility, is one of the principal manifestations of Alzheimer's disease (AD). Weight loss may be associated with protein and energy malnutrition leading to severe complications (alteration of the immune system, muscular atrophy, loss of independence). Various explanations have been proposed such as atrophy of the mesial temporal cortex, biological disturbances, or feeding behaviours; however, none has been proven. Prevention of weight loss in AD is a major issue. It requires regular follow-up and must be an integral part of the care plan. The aim of this article is to review the present state of scientific knowledge on weight loss associated with AD. We will consider four points: the natural history of weight loss, its known etiological factors, its consequences and the various management options.

Abstract: OBJECTIVE: To determine the role of persistent apathy in rapid loss of autonomy in Instrumental Activities of Daily Living (IADL) in women with Alzheimer s disease (AD), taking into account the grade of cognitive decline. METHODS: The study was conducted on 272 women from the French REAL cohort. At inclusion patients had a Mini-Mental State Examination (MMSE) score between 10-26. A rapid functional decline was defined as a yearly drop of 4 points or more on the 14-point IADL Lawton scale. Persistent apathy was defined as a frequency score equal to 3 or 4 on the Neuro-Psychiatric Inventory at the three consecutive 6-monthly assessments. RESULTS: 27.6% of women had rapid functional decline in 1 year and 22.1% of them had persistent apathy. A logistic regression analysis showed that, in addition to cognitive decline, persistent apathy plays a role in rapid functional decline in 1 year. For example, for a 3-point decline in MMSE in 1 year, the probability of a rapid loss in IADL is 0.45 for women with persistent apathy compared with 0.28 for those without persistent apathy. CONCLUSIONS: In this study, a rapid loss in IADL score was partly explained by persistent apathy.

Abstract: BACKGROUND/AIMS: To determine patterns of loss of abilities in instrumental activities of daily living (IADL) in community-dwelling women with Alzheimer's disease (AD). METHODS: Sixteen French university hospitals included 471 consecutive women with mild to moderately severe AD (Mini-Mental State Examination scores between 10 and 26) from April 2000 to June 2002 in the noninterventional REAL cohort. At inclusion, 6 and 12 months, IADL were assessed with the Lawton scale. Patterns of loss of abilities in the 8 IADL of the Lawton scale were described using Lawton binary grading. RESULTS: At inclusion, 56.7% of the patients shared the same pattern of loss of abilities and 84.3% had this pattern or variants of it. Frequencies of the 8 incapacities were: 80.7% to do the grocery shopping, 76.0% to take medication, 72.2% to prepare meals, 41.4% to travel on public transportation even when assisted, 40.6% to manage purchases, 30.1% to launder small items, 14.2% to participate in some housekeeping tasks and 11.0% to answer the telephone. CONCLUSION: In this study including 471 community-dwelling women with AD of the French REAL cohort, the loss of the 8 IADL, assessed with the Lawton binary grading, was homogeneous for more than four fifths of the patients.

Abstract: BACKGROUND: Apathy and depression are the most common neuropsychiatric features in Alzheimer's disease (AD). The clinical and functional specific correlates of these syndromes are not well known independently from cognitive deficits and other behavioral disturbances. MATERIAL AND METHODS: Six hundred and eighty-six patients diagnosed with possible or probable AD were included in a prospective multicenter study (REAL-FR). They had an assessment of their cognitive and functional status. Neuropsychiatric symptoms were assessed with the Neuropsychiatric Inventory (NPI) and caregiver's burden was measured with Zarit's Burden Scale. RESULTS: A majority of patients at any stage of the disease presented with one or several behavioral and psychological disturbances. Apathy concerned 43% of patients and, with or without depression, was associated with more pronounced deficits in global cognition, everyday life and instrumental abilities, nutritional status and with a higher burden level. A high level of psychotropic prescription, especially with antidepressant, was observed in patients with apathy. In a multivariate analysis taking into account the cognitive and functional variables of AD, apathy and depression were the only significant predictors of psychotropic prescription. CONCLUSION: Some negative neuropsychiatric symptoms such as apathy and depression have a specific relation with functional and therapeutic outcomes of AD, independently from cognitive status. Further studies are needed to establish if apathy represents a particularly severe phenotype of AD.

Abstract: Alzheimer's disease is characterised by a progressive loss of autonomy in activities of daily living. Many patients lose this autonomy rapidly with dramatic consequences for the patients and their relatives, and for health and social services. The aim of this study was to determine, in a large French cohort of community-living Alzheimer patients (REAL.FR), the factors underpinning different rates of loss of autonomy. Six hundred and eighty seven patients were recruited to this French cohort. Autonomy in activities of daily living was estimated with the IADL scale (Lawton). Patients were divided into three groups according to loss of autonomy during the first one-year follow-up period. Patients with a decrease in the IADL score had worse ADAS-cog score (Alzheimer's Disease Assessment Scale, cognitive subscale), Mini-Mental State Examination (MMSE), and Clinical Dementia Rating Scale scores. Up to a point, a marked decrease in the IADL score was less frequent among patients with a better ADAS-cog score (p < 0.10, bilateral test). At one-year evaluation, patients with a marked decline in autonomy were characterised by a greater decrease in Mini-Mental State score, faster progression of behavioural disturbance, and more hospitalisations. Further prospective studies, using established models, are needed to isolate the factors associated with a high rate of loss of autonomy in activities of daily living in Alzheimer patients.

Abstract: Behavioral and Psychological Symptoms are major and frequent manifestations of Alzheimer's Disease (AD). The aim of the present study was to evaluate neuropsychiatric symptoms in the PHRC REAL.FR cohort (for Réseau sur la maladie d'Alzheimer Français) after one year of evolution. Four hundred and eighty two patients with mild and moderate AD were assessed. A majority of them had significant symptoms at inclusion (85.3 % of subjects with mild AD, 89.7% of patients with a moderate AD). Patients with mild AD had a significant increase of the Neuropsychiatric Inventory (NPI) frequency x severity scores for apathy and aberrant motor behavior. Patients with moderate AD had a significant increase of NPI disinhibition, aberrant motor behavior and sleep disorders scores. The variation of NPI total score at one year correlated positively with change in Zarit's caregiver burden score, independently of global cognitive evolution. After one year, a group of 54 patients were institutionalized in nursing home or long term care unit. When compared to non institutionalized patients, the institutionalized group was characterized at base line by a lower MMSE score, a higher Zarit caregiver burden score, and a higher NPI agitation and disinhibition scores.

Abstract: Behavioral and Psychological Signs and Symptoms of Dementia (BPSD) are important manifestations of Alzheimer's Disease (AD) and other forms of dementia, because they are associate with care-giver distress, increase the likelihood of institutionalization, and may be associated with more rapid cognitive decline In this study (REAL.FR for Réseau sur la maladie d'Alzheimer Français) we prospectively used the Neuropsychiatric Inventory NPI to examine BPSD. 255 AD patients with a Mini-Mental State Examination (MMSE) score between 11 and 20 and 244 AD patients with a MMSE between 21 and 30 were examined. Factor analysis was carried out leading to three different syndromes according to the level of cognitive impairment. BPSD were detected in 92.5% of the patients with a MMSE between 11 and 20, and in 84% of the patients with a MMSE between 21 and 30. Apathy was the most common abnormality, followed by anxiety and dysphoria. These results in a French cohort of patients with AD underline the importance of the evaluation and finally of the treatment of BPSD.

Abstract: Weight loss is common in elderly people with dementia, particularly those with Alzheimer' disease (AD), and feeding difficulties are major issues in their care in the later stages of the disease. In this study (REAL FR for Réseau sur la maladie d'Alzheimer Français) we prospectively used the Mini Nutritional Assessment (MNA) to examine the nutritional status of 479 subjects. Three groups of patients were studied: group 1 = 22 patients with undernutrition (MNA = 17), group 2 = 166 patients with risk of undernutrition (17 < MNA < 24), and group 3 = 291 patients without undernutrition (MNA = 24). Correlations with behavioral and psychological signs and symptoms of dementia (Neuropsychiatric Inventory NPI), with caregiver distress (Zarit), and with the Mini Mental State Examination (MMSE) were studied. Undernutrition is more frequently associated with low MMSE (p < 0.001), high behavioural disturbances (p < 0.001) and high distress of caregivers (p < 0.001). Risk of undernutrition is also associated with NPI (p < 0.001) and Zarit (p < 0.001). These first results in a French cohort of patients with AD underline the importance of the evaluation of nutritional status and finally the follow-up of eating behavior, cognitive status and the quality of life of the caregivers.

Abstract: PURPOSE: Twice out off three, patients with Alzheimer's disease (AD) are aged 80 and older. Very old patients are more frail, have social precariousness and have often polypathology. Few data are available about these elderly patients. The aim of our study was to analyse characteristics of AD patients aged 80 and older. MATERIAL AND METHODS: This is a prospective, multicentric French study (REAL.FR) of a cohort of ambulatory AD patients, with Mini-Mental State values between 10 and 26. Clinical and social data at inclusion of patients aged 80 and older and patients younger were compared. RESULTS: Six hundred eighty nine patients (488 women, 201 men) were included between April 2000 and June 2002. The mean age was 77.8 +/- 6.9 years. Two hundred sixty four patients (38%) were aged 80 and older. Those patients were more dependant for Activities of Daily Living (ADL) than younger patients (ADL score of Katz: 5.2 +/- 1.07 et 5.6 +/- 0.74 respectively; p < 0.001 and IADL (Instrumental Activities of Daily Living) score of Lawton: 7.3 +/- 3.57 et 9.3 +/- 1.57 respectively; p < 0.001). Duration of evolution of the disease were comparable between older and younger patients. CONCLUSION: In our cohort, AD patients aged 80 and older had a weakest autonomy for the ADL than younger patients with the same stage of the disease. Results has implications on care. Following the cohort will permit to specify evolution of data.

Abstract: BACKGROUND: Cognitive impairment is associated with functional impairment in patients with Alzheimer's disease (AD). Behavioural disturbance is very common in these patients. Nevertheless, there has been very little research into the relations between behavioural disturbance and functional status in AD. The purpose of this study is to investigate the relationship between behavioural disturbance and functional status after taking account of cognitive impairment. MATERIAL AND METHODS: 579 patients were prospectively evaluated at 16 French hospitals, all referents for AD, and were diagnosed with possible or probable AD. These patients were assessed with NeuroPsychiatric Inventory (NPI), cognitive subscales of the Alzheimer's Disease Assessment Scale (ADAS-cog), Clinical Dementia Rating scale (CDR) and Instrumental Activities of Daily Living scale (IADL). RESULTS: The number of men with available data for IADL total score was too small to make any analysis. 'Group A' gathered 256 women for whom the relation between autonomy for Activities of Daily Living (ADL) and the other variables were determined. 'Group B', pooled 85 women for whom relations found were verified. Linear regression was used for the analysis. With age, cognitive impairment allows us to explain best (38%) the loss of autonomy for ADL. CONCLUSION: The role of behavioural disturbances in the loss of autonomy for ADL was not determinant in our study, whereas cognitive impairment and age were better able to determine the loss of autonomy for ADL. Further study is needed to explain the decline of functional status in AD patients.
