Chronic pain (CP) was associated with impaired cognitive performance in several cross-sectional studies conducted in older adults; however, fewer longitudinal studies assessed this link that remains still debated. With a prospective design, the present analysis was aimed at evaluating the relationship between CP and the change in several tests assessing memory, attention, verbal fluency, and processing speed. The study population was selected from the PAQUID study, a cohort of community dwellers aged 65 years and older; 693 subjects receiving a pain assessment were included. Chronic pain was evaluated using a questionnaire administered at 3-year follow-up. Cognitive performances were assessed every 2 to 3 years between 3 and 15 years assessing general cognition (Mini-Mental State Examination), verbal and visual memory (word paired-associate test and Benton test), attention and speed processing (Wechsler Digit Symbol Substitution Test and Zazzo's Cancellation Task), and language skills and executive functions (Isaacs Set Test). The link between CP and the change in cognitive function was assessed with latent process mixed models controlled for age, sex, education, comorbidities, depression, and analgesic drugs. The association between CP and each of the cognitive scores was then tested with the same procedure. A significant relationship was observed between CP and poorer 15-year scores on global cognitive performance (P = 0.004), and specifically, the Digit Symbol Substitution Test (P = 0.002) was associated with a higher slope of decline (P = 0.02). Chronic pain is associated with a higher cognitive decline, particularly in processing speed. This result reinforces the importance of actively treating CP with pharmacological and nonpharmacological strategies to prevent its consequences, including cognitive consequences.

International audience; BACKGROUND: People with dementia (PWD) and their caregivers are populations highly vulnerable to COVID-19 pandemic and its consequences. A better knowledge of the living conditions during the first lockdown is necessary to prevent the risk of poor mental health (PMH) in this population. OBJECTIVE: The present study aimed to compare the mental health of caregivers of PWD living at home or in nursing-homes and to identify specific factors influencing their mental health. METHODS: We conducted an anonymous cross-sectional online survey in France from March 17 to May 11, 2020. Three hundred and eighty-nine caregivers accompanying a PWD living at home (HC) and 159 accompanying a PWD living in a nursing home (NHC) participated in the study. Caregivers' mental health including anxiety, depression, stress, and burden was assessed with self-reported standardized scales. RESULTS: Half of the caregivers exhibited PMH, including depression, anxiety, or self-reported stress. Similar PMH rates were provided whatever the PWD place of residence. Regarding HC, our results also highlighted a number of risk factors for PMH, including the fact that caregiver live with PWD, to give increased support to PWD, and to feel more isolated for managing PWD since lockdown. CONCLUSION: PMH was observed for caregivers of PWD during lockdown, whatever PWD living place, suggesting that concern for PWD may explain more of caregiver distress than increased material tasks. In the future, it will be necessary to pay attention to caregivers after the crisis by estimating the longer-term impact on their mental health.

Numerous neuropsychological studies have investigated the effect of music on patients with Alzheimer's disease. Findings suggest that music can improve behavioral symptoms, but its potential effects on cognitive abilities of patients still require more investigation. In this 2 × 2 crossover study, we measured the impact of learning an individualized song on autobiographical memory recall and other cognitive abilities in 12 patients with mild to moderate Alzheimer's disease. For each patient, one favorite song of the patient and one autobiographical memory with positive valence were associated to create a new personalized song. This song was taught to the patient by a speech and language therapy student throughout 10 sessions. This training period and a non-training period were proposed in a counterbalanced order between participants. We tested participants' autobiographical recall and general cognitive abilities at three time points: at the start of the experiment, at crossover, and at the end of the experiment. After excluding one outlier, results showed a significant improvement in the retrieval of the autobiographical memory and in general cognitive abilities after song training compared to the non-training period. Overall, our findings suggest that the use of personalized songs may be a useful and motivating tool for addressing the decline of autobiographical memory and of cognitive functions in general in persons with Alzheimer's disease.

BACKGROUND The 2008-2012 French Alzheimer's Plan has provided hospital Cognitive and Behavioral Units (CBU) to improve the management of patients with productive behavioral and psychological symptoms of dementia (BPSD). Little is known concerning the behavioral outcome of these patients after discharge. OBJECTIVE The present study investigated the long-term evolution of BPSD over one year after CBU discharge. METHODS The EVITAL cohort included 221 participants admitted to the CBUs of 3 French hospitals. BPSD were collected using the Neuropsychiatric Inventory (NPI) at admission and 3, 6, and 12 months after hospitalization. The global NPI score evolution was assessed using a linear mixed-effect model. A four-factor model of the NPI including behavioral dyscontrol, psychosis, mood, and agitation subscores was also analyzed. RESULTS Our analysis focused on 148 patients followed up during 12 months and evaluated at each visit. The global NPI score was 48.5 (SD 21.7) at baseline, 28.8 (SD 18.7) at 3-month, 23.2 (SD 16.4) at 6-month and 20.9 (SD 15.9) at 12-month follow-up. The score significantly decreased from baseline to follow-up (F = 109.3 p

Background A link between personality traits and cognitive performance has been shown in normal adults and elderly individuals. Very few studies have evaluated this link in Alzheimer's disease (AD). Objective To better understand cognitive performance as regards to personality traits, our study was aimed to evaluate the role of premorbid personality on cognitive functioning in a population of patients presenting prodromal or mild AD. Methods 181 elderly with prodromal or mild AD participated in a cross-sectional, prospective cohort study. The participants completed a personality inventory and a neuropsychological battery exploring memory, attention, executive function, language, and praxis. Cognitive performance were compared according to the level of each personality trait, using multivariate MANOVA models. Results A higher level of neuroticism was associated with lower performance at similarities test (D = 9.49, p = 0.003), delayed Free and Cued Selective Reminding test (D = 5.22, p = 0.02), and digit span score (D = 7.99, p = 0.006). A higher level of openness was related to better performance at similarities (D = 4.33, p = 0.04), letter fluency (D = 11.45, p = 0.001), and category fluency test (D = 5.85, p = 0.02). Neuroticism interfered negatively with cognitive functioning at the prodromal stage; the association between openness and cognitive function was observed at both prodromal and mild AD stage. Conclusion These results suggest that personality traits, in particular neuroticism and openness, modulate cognitive abilities in patients with early AD. These results encourage the development of stress management programs to prevent its negative effects on cognitive aging.

Objective: The present report aims to evaluate whether singing intervention can bring an immediate benefit that is greater than the one provided by painting intervention on pain and well-being. Methods: Fifty-nine mild patients with Alzheimer disease were randomized to a 12-week singing (n = 31) or painting group (n = 28). In the present analysis, the immediate evolution of pain and well-being was compared across sessions between the 2 groups using mixed-effects models. Results: We observed a significant improvement in well-being for both singing and painting groups immediately after sessions, compared to the assessment before the sessions. We did not observe this improvement across the sessions for pain intensity measurement. Discussion: Our results revealed that both painting and singing interventions provide an immediate benefit on the patients’ well-being.

Background Alzheimer's disease (AD) mainly occurs in elderly individuals. Comorbidities and chronic pain are frequent in this population. Previous studies revealed that personality modulates both chronic pain (CP) andADoccurrence and evolution. Moreover, as pain treatments can induce side-effects, non-drugs treatments, such as art interventions, are interesting alternative therapies for decreasing CP in these patients. Objective Our aim was to assess the potential role of personality traits on art intervention efficacy for reducing CP in a population of patients with mild AD. Methods Design: multicenter randomized controlled trial. Fifty mild AD patients underwent a 12-week art intervention including singing and painting groups. Personality was assessed with the Big Five Inventory before the sessions. CP was measured with Numeric Rating Scale (NRS) [Usual pain (NRS-U) and most Intense pain (NRS-I)], Simple Visual Scale [Usual pain (SVS-U) and most Intense pain (SVS-I)] and Brief Pain Inventory (BPI) before and after the sessions. The influence of personality traits on CP evolution before and after art intervention was assessed with multiple linear regression models. Results A positive association was observed between neuroticism and the evolution of three CP measures including NRS-U (B = 0.34, p = 0.01), SVS-U (B = 0.20, p = 0.04), and BPI-U (B = 0.46, p = 0.02) evolution. No significant relationship was observed between neuroticism and NRS-I, SVS-I and BPI-R evolution. Conclusions Our findings suggest that neuroticism can decrease the efficacy of group art intervention on pain in patients with mild AD. Individual therapies could be more appropriate for these patients. These results emphasize the interest of taking into account patients' personality before proposing them to participate to a group therapy.

BACKGROUND Previous studies showed that a third of patients living at home entered an institution after hospitalization in Cognitive and Behavioral Units (CBUs). OBJECTIVE The main objective of this study was to identify predictors of discharge destination for these patients. The secondary objective was to estimate whether institutionalization can have an impact on a patient's long-term prognosis. METHODS The study population was selected from the EVITAL study and included 140 participants living at home before hospitalization in CBUs. Factors favoring nursing-home admission were investigated and the impact of discharge destinations (i.e., home or nursing home) on patients' prognosis was examined. RESULTS Institutionalized patients were more likely to be women (F = 4.7; p = 0.03), with a higher dementia severity (F = 9.82; p = 0.007), often living alone (F = 19.69; p = 0.001), with a caregiver other than spouse (F = 8.93; p = 0.003), and with a higher patient quality of life (QoL) according to the caregiver (F = 11.73; p = 0.001). When using multivariate logistic linear regressions, we showed a relationship between marital status (OR = 0.19, 95% CI: 0.08-0.43, p

BACKGROUND Among non-pharmacological therapies, musical intervention is often used for patients with Alzheimer's disease (AD) and patients presenting chronic pain. However, their efficacy is still under debate. OBJECTIVE Our aim was to determine the efficacy of choral singing versus painting sessions on chronic pain, mood, quality of life, and cognition in AD patients. METHODS In this multicenter randomized controlled trial, 59 mild AD patients were randomized to a 12-week singing (SG; n = 31) or painting group (PG; n = 28). Chronic pain, anxiety, depression, and quality of life were assessed before, after, and 1 month after the sessions. Cognitive abilities were assessed before and after interventions. The evolution of these different measures was assessed with mixed linear models. The primary data analysis was by intention-to-treat, and completed by a 'per protocol' approach. RESULTS Both singing and painting interventions led to significant pain reduction (Time effect: F = 4.71; p = 0.01), reduced anxiety (Time effect: F = 10.74; p
