[Chronic pain, a clumsy body language]. / La douleur chronique, un langage malhabile du corps.

Early psychological factors, including childhood traumas and personality, play a crucial role in the emergence and persistence of painful symptoms and appears to be frequent in patients with nociplastic pain. Patient care involves validating the reality of their pain and identifying various facets of their suffering, taking into account their individual history and context. A multimodal therapeutic approach, within a bio-psycho-social model, emphasizing psychotherapeutic care, is recommended.

Les facteurs psychologiques précoces, notamment les traumatismes infantiles et la personnalité, jouent un rôle primordial dans l'émergence et la pérennisation des symptômes douloureux, et sont très fréquemment retrouvés chez les patients atteints de douleurs nociplastiques. La prise en charge des patients passe par la validation de la réalité de leur douleur et l'identification des diverses facettes de leur souffrance, en tenant compte de l'histoire et du contexte individuel. Une approche thérapeutique multimodale, dans un modèle de type biopsychosocial et privilégiant la prise en soins psychothérapeutique, est recommandée.

Chronic pain and long-term dementia risk in older adults: Results from a 24-year longitudinal study.

INTRODUCTION: Chronic pain (CP) was associated with cognitive impairment in previous studies. However, the longitudinal association between CP and dementia remains under debate. We aimed to assess the prospective link between CP and long-term dementia risk in a population-based cohort of older participants, considering covariables linked to CP and cognitive functioning. METHODS: The study sample was selected from the PAQUID study, an ongoing cohort of older community-dwellers aged 65 years and over at baseline; Information regarding CP and analgesics consumption was collected using questionnaires. Dementia was clinically assessed every 2 years. The population was divided into 4 groups according to CP and analgesic drugs intake (CP+/A+, CP+/A-, CP-/A+, CP-/A-). An illness-death model was used to estimate the link between CP and incident dementia risk controlled for sex, educational level, comorbidities, depression, antidepressant drugs and analgesics. RESULTS: Five hundred ninety three participants (364 women) who completed a CP questionnaire, were included. They were followed-up over 24 years (mean follow-up: 11.3 years, SD 7.3). A total of 223 participants (32.5%) had CP, among them 88 (38.6%) took analgesic drugs. Compared to CP-/A- group, CP+/A+ participants had a higher risk of developing dementia in the univariate model (hazard ratio (HR) = 1.73, 95%CI:1.18-2.56; p = 0.0051). However, these results did not persist in the multivariate models (aHR = 1.23, 95%CI:0.88-1.73; p = 0.23). No significant risk for dementia were observed in CP-/A+ and CP+/A- (HR = 1.30, 95%CI:0.84-2.01; p = 0.23 and HR = 1.36, 95%CI:0.95-1.96; p = 0.09, respectively). CONCLUSION: Our results failed to show a significant relationship between the presence of CP and long-term dementia risk, suggesting that the cognitive decline associated with CP observed in the literature does not appear to be related to Alzheimer's disease or related disorders.

Association between executive function and the evolution of behavioral disorders in Alzheimer's disease.

OBJECTIVE: This study was aimed at evaluating the association between cognitive functioning and the occurrence of behavioral and psychological symptoms of dementia (BPSD) in patients with Alzheimer's disease (AD). METHODS/DESIGN: The population is derived from the PACO cohort, including 237 patients with prodromal or mild AD. A neuropsychological tests battery exploring verbal and visual memory, language, attention, and executive functions was performed at baseline. BPSD were assessed at 6-, 12-, and 18-month follow-up with neuropsychiatric inventory (NPI). RESULTS: Lower baseline performance on Stroop test interference score was associated with higher subsequent overall NPI scores (P = .006), subscores of anxiety/depression (P = .03), and apathy inventory (P = .01). Conversely, other executive functions, verbal or visual memory, and language performances were not associated with a higher risk of BPSD. CONCLUSION: Our results suggest that poorer inhibition performance would be associated with a higher risk of 18-month BPSD occurrence, including anxiety, depression, and apathy. A better knowledge of the predictive factors of the BPSDs would make it possible to better identify the patients at risk, to propose preventive strategies and an earlier adapted care.

Retrieving autobiographical experience of painful events in a phantom limb: brain concomitants in a case report.

We report the case of a patient who had an important experience with painful events, allowing the investigation of brain concomitants to painful (P) memories in fMRI. The patient had to recall P events that were contrasted with non-painful (NP) memories. Painful memories of the right lower limb activated the left paracentral lobule,fronto-insular operculum and superior parietal cortex. Additionally, whilst the recall of non-painful events activated the hippocampus, the recall of painful events did not enhance the hippocampal signal to significant levels. These suggest that brain activations differ for the autobiographical recall of painful and non-painful memories.

Attentional focus on subjective interoceptive experience in patients with fibromyalgia.

OBJECTIVES: The hypervigilance model of pain perception states that patients with fibromyalgia (FM) have an enhanced sensitivity to aversive and non-aversive stimuli. Few studies have focused on enhanced interoceptive sensitivity in FM. Therefore, the aim of the present study was to investigate spontaneous sensations (SPS) in FM. DESIGN: SPS are those tingling, tickly and other kind of sensations usually perceived on the skin during periods of rest and without any external trigger. Therefore, we have investigated SPS by requiring participants to focus attention on each hand. METHODS: Eighteen patients with a diagnosis of FM and 18 matched healthy participants had to direct their gaze toward the hand tested for a period of 10s. Subsequently, they had to map and report the intensity, the number and the qualitative properties of sensations arising spontaneously. Finally, participants had to fill out questionnaires assessing cognitive and affective status that may influence the interoceptive sensations feedback. RESULTS: Patients with FM perceived SPS as significantly more intense than controls did. Additionally, SPS were perceived by the FM group as occupying an overall larger area on the hand than those reported by controls. Importantly, entering scores of pain and catastrophism as covariates produced a relative effect on the feeling of SPS. CONCLUSIONS: The outcome of this study supports the generalized hypervigilance model, suggesting that patients with FM have a perceptual style of amplification of non-aversive interoceptive stimulation, modulated by pain and catastrophizing. This is discussed in relationship to interoceptive awareness.

[Chronic pain: emotional and cognitive consequences]. / Douleur chronique: son retentissement émotionnel et cognitif.

Chronic pain which had become a major public health problem, is always accompanied with emotional and cognitive disorders. These comorbidities are circular and auto generated as in low back pain or in somatoform pain as fibromyalgia. Cerebral imagery of pain show the superposition of emotional and cognitive circuits especially in frontal regions from where come the descending control of pain. Therefore common areas regulate the three functions. Consequences on semiology and treatment of chronic pain are discussed.

Metabolic syndrome is associated with poor memory and executive performance in elderly community residents: the PROOF study.

OBJECTIVE: Aging is associated with a loss of cognitive performance and an increasing occurrence of cardiovascular events. Moreover, cardiovascular risk factors are linked to cognitive impairment and dementia. Whereas individual components of metabolic syndrome (Met S) have been reported to be linked to cognitive decline and dementia, there are very few studies on Met S as a whole. The present study aims to assess the relationship between Met S and its components and cognitive functioning in a cohort of elderly non-demented community residents. DESIGN: Population-based cohort study (PROOF study). Cross-sectional analysis. PARTICIPANTS: Dementia-free community-dwellers aged 65. MEASURES: The PROOF participants underwent an extensive neuropsychological battery at baseline. Summary cognitive measures including memory, attention, and executive performance were created by converting the individual test results to Z scores and computing the average scores within each domain. Each of the three cognitive scores was individually compared between groups as a function of Met S. The cognitive scores and the covariates which were significant in univariate analyses were then included in logistic regression models. RESULTS: A significant association was observed between the presence of metabolic syndrome, poor memory, and executive function even after adjusting for confounding factors (memory: odds ratio: 1.77, p = 0.008; executive functions: odds ratio: 1.91, p = 0.002). CONCLUSIONS: Our study showed that in a sample of elderly community dwellers, Met S was associated with poor memory and executive performance. These results underline the importance of detecting and managing metabolic syndrome components to prevent cognitive impairment and dementia.

Initial and long-term evaluation of patients with Alzheimer's after hospitalization in cognitive and behavioural units: the EVITAL study design.

BACKGROUND: Alzheimer's disease and related disorders are characterized by cognitive impairment associated with behavioral and psychological symptoms of dementia. These symptoms have significant consequences for both the patient and his family environment. While risk factors for behavioral disorders have been identified in several studies, few studies have focused on the evolution of these disorders. Moreover, it is important to identify factors linked to the long-term evolution of behavioral disorders, as well as patients' and caregivers' quality of life. Our purpose is to present the methodology of the EVITAL study, which primary objective is to determine the factors associated with the evolution of behavioral disorders among patients with Alzheimer's disease and related disorders during the year following their hospitalization in cognitive and behavioral units. Secondary objectives were 1) to assess the factors related to the evolution of behavioral disorders during hospitalization in cognitive and behavioral units; 2) to identify the factors linked to patients' and caregivers' quality of life, as well as caregivers' burden; 3) to assess the factors associated with rehospitalization of the patients for behavioral disorders in the year following their hospitalization in cognitive and behavioral units. METHOD/DESIGN: A multicenter, prospective cohort of patients with Alzheimer's disease and related disorders as well as behavioral disorders who are hospitalized in cognitive and behavioral units. The patients will be included in the study for a period of 24 months and followed-up for 12 months. Socio-demographic and environmental data, behavioral disorders, medications, patients and caregivers quality of life as well as caregivers burden will be assessed throughout hospitalization in cognitive and behavioral units. Follow-up will be performed at months 3, 6 and 12 after hospitalization. Socio-demographic and environmental data, behavioral disorders, medications, patients and caregivers quality of life, unplanned rehospitalization as well as caregivers burden will also be assessed at each follow-up interview. DISCUSSION: The present study should help better identify the factors associated with reduction or stabilization of the behavioral and psychological symptoms of dementia in patients with Alzheimer's disease. It could therefore help clinicians to better manage these symptoms. TRIAL REGISTRATION: Clinical Trials NCT01901263. Registered July 9, 2013.

Personality, Alzheimer's disease and behavioural and cognitive symptoms of dementia: the PACO prospective cohort study protocol.

BACKGROUND: Alzheimer's disease is characterised by a loss of cognitive function and behavioural problems as set out in the term "Behavioural and Psychological Symptoms of Dementia". These behavioural symptoms have heavy consequences for the patients and their families. A greater understanding of behavioural symptoms risk factors would allow better detection of those patients, a better understanding of crisis situations and better management of these patients. Some retrospective studies or simple observations suggested that personality could play a role in the occurrence of behavioural symptoms. Finally, performance in social cognition like facial recognition and perspective taking could be linked to certain personality traits and the subsequent risks of behavioural symptoms. We propose to clarify this through a prospective, multicentre, multidisciplinary study. Main Objective: -To assess the effect of personality and life events on the risk of developing behavioural symptoms. Secondary Objectives: -To evaluate, at the time of inclusion, the connection between personality and performance in social cognition tests; -To evaluate the correlation between performance in social cognition at inclusion and the risks of occurrence of behavioural symptoms; -To evaluate the correlation between regional cerebral atrophy, using brain Magnetic Resonance Imaging at baseline, and the risk of behavioural symptoms. METHODS/DESIGN: Study type and Population: Prospective multicentre cohort study with 252 patients with Alzheimer's disease at prodromal or mild dementia stage. The inclusion period will be of 18 months and the patients will be followed during 18 months. The initial evaluation will include: a clinical and neuropsychological examination, collection of behavioural symptoms data (Neuropsychiatric-Inventory scale) and their risk factors, a personality study using both a dimensional (personality traits) and categorical approach, an inventory of life events, social cognition tests and an Magnetic Resonance Imaging. Patients will be followed every 6 months (clinical examination and collection of behavioural symptoms data and risk factors) during 18 months. DISCUSSION: This study aims at better identifying the patients with Alzheimer's disease at high risk of developing behavioural symptoms, to anticipate, detect and quickly treat these disorders and so, prevent serious consequences for the patient and his caregivers.

A whole-grain-rich diet reduces urinary excretion of markers of protein catabolism and gut microbiota metabolism in healthy men after one week.

Epidemiological studies consistently find that diets rich in whole-grain (WG) cereals lead to decreased risk of disease compared with refined grain (RG)-based diets. Aside from a greater amount of fiber and micronutrients, possible mechanisms for why WGs may be beneficial for health remain speculative. In an exploratory, randomized, researcher-blinded, crossover trial, we measured metabolic profile differences between healthy participants eating a diet based on WGs compared with a diet based on RGs. Seventeen healthy adult participants (11 female, 6 male) consumed a controlled diet based on either WG-rich or RG-rich foods for 2 wk, followed by the other diet after a 5-wk washout period. Both diets were the same except for the use of WG (150 g/d) or RG foods. The metabolic profiles of plasma, urine, and fecal water were measured using (1)H-nuclear magnetic resonance spectroscopy and gas chromatography-mass spectrometry (plasma only). After 1 wk of intervention, the WG diet led to decreases in urinary excretion of metabolites related to protein catabolism (urea, methylguanadine), lipid (carnitine and acylcarnitines) and gut microbial (4-hydroxyphenylacetate, trimethylacetate, dimethylacetate) metabolism in men compared with the same time point during the RG intervention. There were no differences between the interventions after 2 wk. Urinary urea, carnitine, and acylcarnitine were lower at wk 1 of the WG intervention relative to the RG intervention in all participants. Fecal water short-chain fatty acids acetate and butyrate were relatively greater after the WG diet compared to the RG diet. Although based on a small population and for a short time period, these observations suggest that a WG diet may affect protein metabolism.

Impaired emotional processing in a patient with a left posterior insula-SII lesion.

The present case-report investigated the influence of a lesion in the left posterior insula-SII cortices on the processing of emotions. MB and 16 normal controls explicitly rated the valence and the intensity of both facial expressions and emotional words. In addition, they had to perform a number comparison task and a lexical decision task without focusing their attention on emotional components of stimuli. MB identified the valence of emotional words as well as the control group. Nevertheless, she provided higher intensity scores for disgusted words and her responses in the lexical decision task were significantly delayed for these stimuli. In addition, MB's response times were not differently influenced by the presence of irrelevant emotional faces. However, she explicitly identified fewer facial expressions of disgust and she assessed them as significantly less intense. This pattern of results contributes to highlight the psychological and behavioral disorders observed after a left posterior insular stroke.

[Functional imaging of pain: from the somatic response to emotions]. / L'imagerie fonctionnelle de la douleur : de la réponse somatique à l'émotion.

Functional brain imaging in subjects experiencing pain (real, observed or imagined) has led to considerable progress in our understanding of the role of the brain andpsyche in pain integration and control, as well as some forms of somatoform pain with no anatomical basis. This research is challenging not only the dichotomy between the soma and psyche, but also the concept of psychosomatic pain.

Executive Profile of the Logopenic Variant of Primary Progressive Aphasia: Comparison with the Semantic and Non-Fluent Variants and Alzheimer's Disease.

The logopenic variant of primary progressive aphasia (lvPPA) shows different features from the non-fluent (nfvPPA) and semantic (svPPA) variants of PPA. Although language impairments remain the core symptoms, studies have highlighted the presence of executive disorders at the onset of the disease. Nevertheless, the results are contradictory, particularly in lvPPA. The aim of this study was to explore the executive profile of lvPPA. We compared executive functioning in lvPPA with the other two variants of PPA, Alzheimer's disease (AD) and a cognitively healthy group. In total, 70 patients with PPA, 32 patients with AD, and 41 healthy controls were included. They underwent a comprehensive executive battery assessing short-term and working memory, inhibition, flexibility, planning, and initiation. The analyses showed significant differences between the lvPPA group and the control group, except on visuospatial spans and the Stroop test, and between the lvPPA group and the other PPA groups and the AD group for several tasks. Thus, this research highlighted the existence of an executive dysfunction from the onset of the disease in lvPPA but also in the other two variants of PPA.

Psychiatric disorders, personality traits, and childhood traumatic events predicting incidence and persistence of chronic pain: results from the CoLaus|PsyCoLaus study.

ABSTRACT: Chronic pain (CP) is often accompanied by mental disorders (MDs). However, little is known concerning the long-term effect of MDs, personality traits, and early-life traumatic events (ETEs) on CP course. Accordingly, we aimed to prospectively assess the associations of major depressive disorders (MDDs), anxiety disorders, personality traits, and ETEs with the incidence and the persistence of CP in middle-aged and older community dwellers. Data stemmed from the 3 first follow-up evaluations of CoLaus|PsyCoLaus, a prospective cohort conducted in the general population of Lausanne (Switzerland). Diagnostic criteria for MDs and ETEs were elicited using semistructured interviews. CP and personality traits were assessed by self-rating questionnaires. Follow-up intervals were subdivided into 2 groups: those without (n = 2280) and those with (n = 1841) CP initially. The associations between the psychological variables and the occurrence or persistence of CP 5 years later were assessed using serially adjusted logistic regression models. Higher neuroticism (odds ratio [95% confidence interval] 1.21 [1.08; 1.36]) and extraversion (1.18 [1.06; 1.32]) were associated with higher 5-year CP incidence, whereas current (2.14 [1.34; 3.44]) and remitted MDD (1.29 [1.00; 1.66]) as well as lower extraversion (0.83 [0.74; 0.94]) were associated with persistence of CP. By contrast, ETEs and anxiety disorders were not associated with the incidence or persistence of CP. Our results suggest that personality traits are associated with both CP occurrence and persistence, whereas the MDDs may be more associated with CP persistence. Both personality and MDD are accessible to psychotherapy, and MDD is also accessible to pharmacotherapy. Hence, these therapeutic measures might decrease the risk of CP and its persistence.

Diabetes, impaired fasting glucose, and cognitive decline in a population of elderly community residents.

BACKGROUND AND AIMS: Diabetes and impaired fasting glucose, as well as cognitive impairment, are common in the elderly. Although several cross-sectional studies have demonstrated the influence of diabetes on cognitive impairment, only a few longitudinal studies have assessed the relationship between diabetes, impaired fasting glucose and cognitive decline in non-demented elderly community dwellers, by means of extensive neuropsychological batteries. The present study assesses the relationship between baseline diabetes, impaired fasting glucose (IFG) and 2- year evolution of memory, attention and executive performance in a sample of non-demented elderly subjects. DESIGN: Population-based cohort study [(PROgnostic indicator OF cardiovascular and cerebrovascular events (PROOF)]. PARTICIPANTS: One hundred and sixty-three community dwellers aged 65 years without dementia at recruitment. MAIN OUTCOME MEASURES: Memory, attention and executive performance. RESULTS: A significant association was observed between baseline diabetes mellitus and a higher 2-year decline in the Trial Making Test B and Stroop test exploring attention and executive function. This effect remained significant after adjusting for age, gender, education, anxiety and depressive symptoms, as well as other cardiovascular risk factors (F=2.41; p=0.007). Instead, no relationship was observed between IFG and cognitive decline. CONCLUSIONS: Our study showed that, in a sample of elderly non-demented community dwellers, diabetes mellitus (but not IFG) is associated with a higher decline in selective attention and executive functioning. These results emphasize the importance of detecting and man- aging diabetes and impaired fasting glucose, in order to prevent cognitive impairment and dementia.

Processing of Facial Expressions of Emotions and Pain in Alzheimer's Disease.

BACKGROUND: Alzheimer's disease (AD) is a neurodegenerative pathology that disrupts processing of facial expressions of emotion. The impairment was demonstrated for negative emotions in tasks of matching, discriminating, and labeling facial expressions but no study has included the expression of pain in its protocol. OBJECTIVE: The objective was to study the processing of emotional facial expressions in AD with a particular interest in pain expression. METHODS: Twenty-seven controls, 15 mild AD patients, and 15 moderate AD patients had to perform four emotional tasks: identification of facial expressions, matching pain expressions, discriminating the intensity of pain expressions, and judging pain intensity. RESULTS: Some emotions were less efficiently recognized by AD patients compared to controls (p < 0.001), specifically fear from the mild stage (p < 0.05), pain and disgust from the moderate stage (p < 0.05 and p < 0.001 respectively). The Exploratory Factor Analysis showed that recognition of pain and recognition of other discreet emotions were underpinned by two different latent factors. Performances on pain expression matching task and pain intensity discrimination task did not differ by group. (p = 0.334 and p = 0.787 respectively). Finally, moderate AD patients judged the pain less intensively than the Control group for both, moderate, and severe pain intensity (p < 0.001). CONCLUSION: Our data suggest that AD disrupts the recognition of pain expression along with recognition of fear and disgust. Additionally, AD patients seem to underestimate pain intensity compared to controls. The self-rated pain scales should be adapted to the pain processing deficit of AD patients.

Association between depressive symptoms and long-term heart rate variability in older women: Findings from a population-based cohort.

INTRODUCTION: Cross-sectional studies highlighted changes in autonomic nervous system (ANS) activity in geriatric depression. However, few longitudinal studies assessed this link which remains still debated. We examined the longitudinal association between lifetime depression history, current depressive disorders, and the evolution of ANS activity in older community women. METHODS: The present data stemmed from the PROOF study, a population-based cohort of 1011 community-dwellers followed-up at 2-year intervals for 10 years. Only data from female participants was analyzed (n = 508, mean age 68.5 ± 0.88 years), as very few men had depression in our population. Depressive symptoms and depression history were collected at baseline. Participants were classified in four groups according to presence or absence of history of depression (HD) or current depressive symptomatology (CD): HD+/CD+, HD-/CD+, HD+/CD- and HD-/CD-. ANS activity was assessed during the follow-up through 24-h heart rate variability (HRV). Longitudinal associations between depressive status and HRV indices during the follow-up were investigated using multivariate linear mixed models. RESULTS: Compared to HD-/CD- group, women belonging to HD-/CD+ group had greater baseline parasympathetic tone, as measured by lower LF index and LF/HF balance. The longitudinal analysis exhibited a significant enhancement of LF/HF balance with time, measuring an increase of sympathetic tone in HD-/CD+ group. CONCLUSION: Our findings suggest that late-onset depressive symptoms may be associated with subsequent autonomic dysregulation in older women. These results highlight the importance of detecting and managing depressive symptoms to limit their consequences on ANS functioning, and the risk of cardiovascular events.

Stress, Personality, Attachment, and Coping Strategies During the COVID-19 Pandemic: The STERACOVID Prospective Cohort Study Protocol.

Background: Due to the lockdown linked to the COVID-19 pandemic, the French National Authority for Health has recommended reinforced follow-up of psychiatric patients, with particular attention to people over 65 years. Cross-sectional studies reported an increased risk of anxiety, depression, and suicide during this period. Older people with psychiatric disorders are at higher risk of developing severe COVID-19 and worsening their psychiatric symptoms. Objective: The main objective is to evaluate the link between coping strategies and the onset of post-traumatic stress disorder (PTSD) after lockdown. The secondary objective is to assess the psychological factors influencing lockdown experiences such as personality, attachment type, or coping strategies. Method/Design: this is a multicenter cohort study including 117 patients followed up by phone in two French geriatric psychiatry units. Sociodemographic variables, psychiatric diagnoses, lockdown conditions, coping strategies, anxiety, and depressive symptoms reported during the first lockdown will be collected retrospectively from the medical file. A first prospective assessment including personality traits, attachment type, and traumatic life events will be conducted at 12 months (T1). Follow-up visits assessing anxious-depressive symptoms and PTSD will be made 18 (T2) and 24 months (T3) after the first lockdown. The primary outcome measure is PTSD symptoms. Secondary outcomes measures are coping strategies, generalized anxiety, anxiety about the COVID-19 pandemic, and quality of life. Discussion: This study aims to determine if the type of coping strategies usually employed have an impact on the onset of PTSD after a lockdown period. It will also determine if these coping strategies are influenced by other factors such as sociodemographic variables, lockdown conditions, particular personality traits, attachment type, and traumatic life events. This study could help identify factors associated with a poorer experience of lockdowns and pandemic crisis in elderly patients followed in a psychiatric center, and guide support in future similar situations.

Anxiety, depression and coping evolution during the Covid-19 pandemic in older people with psychiatric diseases / Anxiété, dépression et évolution du coping durant la pandémie de Covid-19 dans une population de patients âgés avec troubles psychiatriques

Introduction: Lockdown over the Covid-19 pandemic might have had a major impact on people's mental health. The present longitudinal study was aimed to explore the impact of the two first lockdowns on anxious and depressive symptoms of older subjects suffering from psychiatric disorders and to highlight their strategies to cope with the stress induced by these lockdowns. Methods: Twenty-one outpatients from psychogeriatric units benefited from a follow-up visit phone. They filled out questionnaires assessing their anxious (GAD-7) and depressive (Mini-GDS) symptomatology and a questionnaire about their coping strategies (Brief COPE). Results: The depressive symptomatology significantly decreased between the 1st lockdown and the second assessment 9 months later with a GDS score significantly decreasing from 1.7 ± 1.2 to 0.9 ± 1.0. Conversely, anxiety remained stable with a mean GAD-7 score from 6.2 ± 5.1 to 6.3 ± 4.4. Furthermore, coping strategies were correlated with both depressive symptomatology and anxiety. At the same time, coping strategies focused on emotional support, acceptance, selfdistraction, and expression of feeling during the first lockdown had shifted 9 months later towards positive reframing and problem-solving strategies (active coping and planification) with a significant increase of active coping. Conclusion: The study showed that during the Covid-19 pandemic and its lockdown, older subjects with psychiatric disorders were able to engage coping strategies and to mitigate their depressive symptomatology and these coping strategies were flexible according to the context.

Contexte: Le confinement durant la pandémie de Covid-19 a eu un impact majeur sur la santé mentale. Cette étude longitudinale réalisée durant la pandémie avait pour objectif d'évaluer l'impact des deux premiers confinements sur les symptômes anxieux et dépressifs de sujets âgés avec troubles psychiatriques, et de mettre en évidence leurs stratégies d'adaptation pour faire face au stress. Méthodes: Vingt et un patients de psychogériatrie ont bénéficié d'un suivi en téléconsultation. Ils ont renseigné des questionnaires mesurant leur symptomatologie anxieuse (GAD 7) et dépressive (Mini-GDS), et leurs stratégies de coping. Résultats: La symptomatologie dépressive a significativement diminué entre le premier confinement et l'évaluation réalisée neuf mois plus tard (avec respectivement : scores à la Mini-GDS à 1,7 = 1,2 et 0,9 ± 1,0, p = 0,01). En revanche, le niveau d'anxiété ne s'est pas modifié (avec respectivement score GAD7 à 6,2 ± 5,1 et 6,3 ± 6,4, p = 0,4). Par ailleurs, des corrélations significatives entre certaines stratégies de coping, la dépression et l'anxiété ont été observées. Les stratégies de coping centrées sur le soutien émotionnel lors du premier confinement ont évolué vers des stratégies orientées sur la résolution de problème neuf mois plus tard. Ainsi, l'étude a montré que durant cette période de confinement et de pandémie de Covid-19, des sujets âgés ont pu mobiliser des stratégies de coping et atténuer leur symptomatologie dépressive et que ces stratégies ont été modulables selon le contexte.

Anxiety symptoms during COVID-19 in older adults with psychiatric disorders.

Objective: During the COVID-19 pandemic, older people and patients with psychiatric disorders had an increased risk of being isolated. The French National Authority for Health has recommended a reinforced follow-up of these patients. Cross-sectional studies reported an increased risk of developing anxiety and depression during pandemic. The aim of our study was to identify factors associated with higher anxiety during the pandemic in older patients with psychiatric disorders. Methods: STERACOVID is a multicenter cohort study with 117 patients followed-up by phone in two French geriatric psychiatry units. In this work, we used cross-sectional data from a prospective follow-up conducted between January and May 2021. Results: We found that coping strategies, personality, and living conditions were associated with general anxiety (GA) level during the pandemic period. Higher GA was associated with less positive thinking coping strategy, more avoidance strategies, a lower level of extraversion, a higher level of neuroticism, more time spent watching the news, a higher feeling of loneliness, and a lack of physical contact. Findings: Our study identified factors associated with a poorer experience of pandemic crisis. Special attention should be paid to patients with a high level of neuroticism and a high feeling of loneliness. Support could aim to help patients use more functional strategies: reducing avoidance strategies and increasing positive thinking. Finally, reducing time watching news could also be an interesting prevention perspective. Clinical trial registration: clinicaltrials.gov, identifier NCT04760795.
