The recent positive results of phase III clinical trials evaluating the efficacy of anti-amyloid antibodies in Alzheimer's disease may give hope for an approbation in clinical practice soon. Indeed, lecanemab showed cognitive efficacy but also on functional status, quality of life and caregiver burden in the phase III CLARITY study. Aducanumab has already received marketing authorization in the United States in 2021 for the treatment of Alzheimer's disease. However, these clinical trials include mostly young participants without significant comorbidities who are not fully representative of the real elderly population. It is therefore necessary to examine the potential use of these treatments in routine care in the elderly population and to identify potential barriers to their use. The presence of cerebral microbleeds and anticoagulation, two frequent conditions in the elderly, could limit the use of anti-amyloid immunotherapy in the geriatric population. In this population, another limitation would be the unusually long diagnosis delays given that the anti-amyloid therapies target the earliest stages of the disease. However, the results of the phase III trials and in particular the subgroup analyses seem indicate a superior cognitive efficacy in elderly subjects, especially those over 75. European recommendations on the future use of these treatments are therefore awaited to clarify this situation, which will probably require a precise analysis of the benefit-risk balance. Age alone cannot be a contraindication to the administration of these treatments.

Introduction: Presbycusis is the physiological decrease in hearing due to advancing age and begins well before the sixth decade. These recommendations recall the principles of early diagnosis of presbycusis and the means of optimal rehabilitation as soon as the first symptoms appear.

Material and methods: The recommendations are based on a systematic analysis of the literature carried out by a multidisciplinary group of ENT physicians, audiologists, geriatricians and hearing specialists from all over France. They are classified as grade A, B, C or professional agreement according to a decreasing level of scientific evidence.

Results: The diagnosis of presbycusis is more difficult at the beginning of its evolution but a certain number of tools are available for its early diagnosis and its face-to-face or remote management.

Conclusion: In the case of a clinical profile suggestive of presbycusis in a young subject, especially if there are several family cases, it is recommended to propose a genetic investigation. Free-field speech audiometry in noise is recommended to measure intelligibility in a realistic environment. Questionnaires in addition to audiometric tests would allow the best assessment of the patient's disability. Hearing rehabilitation with a hearing aid or cochlear implant may slow or prevent cognitive decline. Combined auditory and cognitive rehabilitation should be offered regardless of the time since the hearing was fitting. It is recommended to integrate programs accessible via smartphones, tablets or the Internet, that include different training domains to complement face-to-face sessions.

Impaired awareness increases dependency of patients suffering from Alzheimer's Disease (AD) and caregivers' burden but remains insufficiently evaluated in clinical practice. The numerous conceptualisations of this symptomatology (anosognosia, denial, insight…) have only a slight impact on the three main assessment methodologies which are: the patient-caregiver discrepancy; the clinician rating of patients' awareness of illness; and the prediction of performance discrepancy methods. Nevertheless, most of evaluating tools are not validated yet, in particular regarding the clinician rating, leading to contrasted results. Most of recent studies reported positive correlations with apathy and AD severity, and negative relationships with depressive symptoms. Therefore, impaired awareness seems to be mainly influenced by patient's depression and apathy. We discuss these correlates and shared aspects of apathy and impaired awareness from neuroanatomical, clinical and conceptual viewpoints. We also highlight the relevance and limits of quantitative and qualitative assessment methods, in particular phenomenological.

Background: In the context of the pandemic Covid-19, the Hospitalization A Home (HAH) of the Assistance Publique - Hôpitaux de Paris (APHP) has implemented a new organisation with emergency interventions to meet the needs of residents in palliative care in nursing home. The objective of the study was to describe their clinical characteristics, the modalities of the intervention and their care pathways during the HAH intervention.

Methods: This is a descriptive study on the emergency intervention of the HAH in 74 nursing home in the area of Ile-de-France during one month (April 2020) with a sample of 132 residents. The data collection included the socio-demographic and clinical characteristics of residents and on data about nursing home included.

Results: Emergency intervention of the HAH in nursing home involved very elderly residents with severe functional disabilities and with signs of respiratory failure linked to the Covid 19. The intervention took place mainly during the day and the week with a territorial heterogeneity and with a double medical validation between the prescribers and the HAH physician. Seventy per cent of the residents died at their living place. Among nursing home included, they were of medium size, mainly with private status and a large majority had already collaborated with the APHP's HAH.

Discussion/conclusion: Emergency intervention of the HAH in nursing home was feasible and responded to an unmeet need for palliative care residents. These results should allow the ongoing development of this new organization for elderly population living in private homes.

Introduction: Lumbar puncture (LP) is an essential diagnostic procedure, which raises major concerns in older adults. Some patients may be denied LP because of the fear of complications in healthcare teams which are not familiar with the procedure. The objectives of our work were to analyze the perspectives and the experiences regarding scheduled LP in cognitively impaired older adults, as well as in their relatives, and the healthcare teams from geriatric day hospitals.

Methods: We conducted a qualitative, observational and multicentric study, based on semi-directive interviews of patients aged over 70 years with cognitive complaints undergoing a scheduled LP in a day hospital. Patients were interviewed before and after LP. Their relatives and the involved healthcare teams were also interviewed to analyze their expectations and perspectives regarding the procedure. The full interviews were transcribed and analyzed using interpretative phenomenological analysis.

Results: Ten patients (mean age 80.2 ± 7.2), five relatives and four healthcare teams were included. The goals and operating procedure of LP were poorly understood by several patients. Some individuals feared irreversible neurological consequences or LP-related pain, which was often overestimated with regards to the post-LP interviews. The patients' major expectation was to establish an accurate and early diagnosis of their cognitive disorder to provide optimal care plan. Relatives reported similar fears of major adverse events. They also expected an accurate diagnosis with biomarkers. The perspectives and experiences of the healthcare teams were heterogeneous, according to their level of practice of LP, but seemed in line with current scientific guidelines.

Conclusion: This study highlighted the existence of false beliefs and poor knowledge regarding the LP procedure and its associated risks. The post-LP patients' feedbacks were better than their expectations, especially in day hospitals with solid experience in LP. Better patient information may be a key to improve our practice.

Introduction: Presbycusis is the physiological decrease in hearing due to advancing age and begins well before the sixth decade. These recommendations recall the principles of early diagnosis of presbycusis and the means of optimal rehabilitation as soon as the first symptoms appear.

Material and methods: The recommendations are based on a systematic analysis of the literature carried out by a multidisciplinary group of doctors and audioprosthetists from all over France. They are graded A, B, C or expert opinion according to decreasing level of scientific evidence.

Results: The diagnosis of presbycusis is more difficult at the beginning of its evolution but a certain number of tools are available for its early diagnosis and its management in face-to-face or even distance learning.

Conclusion: In case of a clinical profile suggestive of presbycusis in a young subject, especially if there are several family cases, it is recommended to propose a genetic investigation. It is recommended to perform free-field speech audiometry in noise to measure intelligibility in an environment as close as possible to reality. Questionnaires can be used in addition to audiometry to best assess the patient's disability. It is recommended that hearing rehabilitation with a hearing aid or cochlear implant may slow or prevent cognitive decline. Combined auditory and cognitive rehabilitation should be offered regardless of the time elapsed since the fitting. It is recommended to integrate programs accessible via smartphones, tablets or the Internet, integrating different training domains in addition to face-to-face sessions.

The aim of this study was to determine the relationship between sarcopenia and calf and neck circumferences. One hundred seventy-seven community-dwelling elderly individuals (over 65 years old) were recruited. A questionnaire was applied via face-to-face interview and the MNA-SF was used to assess nutritional status. In addition, some anthropometric measurements and handgrip strength were assessed by dieticians to determine sarcopenia. Sarcopenia was defined according to the European consensus definition of the EWGSOP-2 criteria. Neck (p<0.001), calf (p=0.001), and waist circumference (p<0.001) were significantly higher in nonsarcopenic elderly women but in men. According to ROC analyses, neck (AUC: 74.7%), calf circumferences (AUC: 74.3%), and BMI (AUC: 80.4%) are possible predictors of sarcopenia in elderly women. This is the first study to demonstrate that neck circumference can be useful for predicting sarcopenia in community-dwelling women over 65 years old. These findings may contribute to the development of new strategies to screen for sarcopenia.

Introduction: Early geriatric rehabilitation programs are potential means to prevent acute hospitalisation-associated functional decline.

Methods: The objectives were to measure the impact of an interdisciplinary rehabilitation program on patients' administrative in hospital data and on functional trajectories. With a before-and-after design, we compared all patients admitted from January to August 2018 into the Acute Care for Elders (ACE) unit of an Academic hospital in Switzerland who received this type of program to those admitted during the same period in 2016 and 2017. We considered vulnerable patients aged 75 or older. Functional independency level was assessed at baseline, admission, and discharge according to Katz's basic activities daily living (BADL).

Results: In total, 378/1,073 patients (mean age 86.6 ± 6.4; 74.6% women; 84% admitted from the emergency department) were prospectively admitted into the ACE unit in 2018. With an adherence rate of 74.0% to functional therapies and compared to the prior years, the program reduced transfers to rehabilitation settings (28.5 vs. 24.3%, p=0.04) and increased direct discharges to home (46.8 vs. 42.4%, p=0.04). Rates of early-unplanned readmission were similar. Between admission to discharge, 89.9% of the patients engaged in the program remained functionally stable or enhanced. Whatever the BADL score at the admission, 46.5% improved their status for at least one BADL. Even though no clinical determinant was identified, patients who engaged ≥ 5 sessions of functional therapy per week were more likely to improve their functional level (OR = 3.05; 95% CI 1.76-5.27).

Conclusion: This real-life study demonstrates arguments to implement early interdisciplinary rehabilitation program in ACE units in particular to prevent functional decline in vulnerable patients. These findings support consideration regarding the interest of switching from the traditional disease-centred approach in acute care for older patients to a modern one, that also put the emphasis on maintaining functional capacities.

Introduction: Dementia with Lewy bodies (DLB) is characterized by neurocognitive disorders associated with core clinical features including hallucinations. There is currently no cure but a combination of symptomatic treatments: clozapine is commonly used in DLB-related psychosis. Pimavanserin is a serotonin 5HT-2A receptor inverse agonist that has recently been shown to reduce psychosis related to dementia. Trazodone is a serotonin reuptake inhibitor and a 5-HT2 receptor antagonist: it is effective in the treatment of the frontal syndrome and is commonly used in frontotemporal degeneration.

Patients and methods: We describe three patients with DLB, hospitalized in the cognitive-behavioral unit of the University Hospitals of Strasbourg, who presented with major visual hallucinations, delusion, and an orbitofrontal syndrome including disinhibition, agitation, and irritability. The 3 patients were intolerant of low-dose Clozapine (neutropenia for one, somnolence for the other and Pisa syndrome and falls for the last one). We evaluated the Neuropsychiatric Inventory (NPI) before and after the introduction of both treatments.

Results: Given their psychotic and frontal symptoms, we used Pimavanserin and Trazodone simultaneously. After 4 to 6 weeks of treatment, a marked improvement was observed in all 3 patients, with a decrease of the NPI scores from a mean of 88 to 38.

Discussion and conclusion: To our knowledge, there is no previously described combination of these two treatments in DLB. A clinical trial combining these two molecules against pervasive behavioral disorders in DLB would be interesting in view of these preliminary results.

Jacques Brel, a French-speaking Belgian popular singer, carries a fatalistic look in his song Les Vieux [The Adged] that makes echoes to the implacable judgment of Charles de Gaulle "Old age is a shipwreck". Old age is synonymous with weakening, exhaustion and even decay. This image must be overcome to face a more nuanced reality, where autonomy is favored; we must developp the care of the frailest people (accessibility of places, geriatric care, home services, medicalized material…). The law is concerned with maintaining or restoring the rights of the most vulnerable people. The presence of cognitive disorders does not necessarily deprive the person of his ability to express himself. Thus, the judge has the obligation to adjust the protective measure to the capacities of the protected person; he/she ensures that his/her opinion is respected. In order to protect without diminishing, the guardianship judge relies in particular on the detailed medical certificate but also on the hearing of the person. It would not be possible for the judge to decide on such delicate issues as home care without the most reliable and concrete information.
