Early-life adversity predicting the incidence of multisite chronic pain in the general population.

Introduction: Adverse childhood events (ACEs) have been linked to widespread chronic pain (CP) in various cross-sectional studies, mainly in clinical populations. However, the independent role of different ACEs on the development of different types of CP remains elusive. Accordingly, we aimed to prospectively assess the associations between specific types of ACEs with the development of multisite CP in a large population-based cohort.

How do theory of mind and formal language skills impact metaphoric reference comprehension during children's school-age years.

Prior research has shown that school-aged children's metaphor comprehension becomes adultlike progressively. This has given rise to claims that the development of metaphor comprehension is due to children's evolving abilities with respect to theory of mind (ToM) or to formal language. The present work investigates the extent to which children's growing sophistication with metaphor is attributable to each of these.

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

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.

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.

Impaired Facial Emotion Recognition and Gaze Direction Detection in Mild Alzheimer's Disease: Results from the PACO Study.

Background: Facial emotion recognition (FER) and gaze direction (GD) identification are core components of social cognition, possibly impaired in many psychiatric or neurological conditions. Regarding Alzheimer's disease (AD), current knowledge is controversial.

Objective: The aim of this study was to explore FER and GD identification in mild AD compared to healthy controls.

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.

Comparative diagnosis interest of NfL and pNfH in CSF and plasma in a context of FTD-ALS spectrum.

Objective: The 'Frontotemporal dementia-Amyotrophic lateral sclerosis Spectrum' (FAS) encompasses different phenotypes, including cognitive disorders (frontotemporal dementia, FTD) and/or motor impairments (amyotrophic lateral sclerosis, ALS). The aim of this study was to apprehend the specific uses of neurofilaments light chain (NfL) and phosphorylated neurofilaments heavy chain (pNfH) in a context of FAS.

Methods: First, NfL and pNfH were measured in 39 paired cerebrospinal fluid (CSF) and plasma samples of FAS and primary psychiatric disorders (PPD) patients, considered as controls.

Does Cognitive Functioning Predict Chronic Pain in Older Adult? Results From the CoLaus|PsyCoLaus Longitudinal Study.

Chronic pain (CP) and cognitive impairment are common in older adults. CP was found to be associated with cognitive impairment in many cross-sectional studies. However, their cross-sectional design precluded inference on temporality.

How do patients with Alzheimer's disease imagine their pain?

Introduction: Pain is underdiagnosed and undertreated in patients with Alzheimer's disease (AD). Pain management is of major importance in this population to limit behavioural and functional consequences. Our study aimed to assess the capacity of AD patients to represent pain using a questionnaire exploring daily painful situations and to determine the most appropriate pain scale assessment.

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.

Neuroticism-Withdrawal and Neuroticism-Volatility Differently Influence the Risk of Neuropsychiatric Symptoms in Alzheimer's Disease.

Background: Neuroticism is recognized as the personality domain that is most strongly associated with behavioral and psychological symptoms (BPS) of Alzheimer's disease (AD). Two sub-components of neuroticism have been recently isolated. Neuroticism-withdrawal (N-withdrawal) refers to the tendency to internalize negative emotion, whereas neuroticism-volatility (N-volatility) reflect the predisposition to externalize negative emotions.

Personality Traits are Related to Selective Cognitive Impairment in Early Alzheimer's Disease.

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.

Does Personality Predict Behavioral and Psychological Symptoms of Dementia? Results from PACO Prospective Study.

Background: Premorbid personality could play a role in the onset of behavioral and psychological symptoms (BPS) in Alzheimer's disease (AD) but prospective studies are lacking.

Objective: The present study aimed at prospectively assessing the influence of premorbid personality traits on BPS evolution in a population of patients with prodromal or mild AD.

Methods: We used a multicenter prospective cohort study of 237 patients followed-up for 18 months.

Personality Modulates the Efficacy of Art Intervention on Chronic Pain in a Population of Patients with Alzheimer's Disease.

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.

Can Musical or Painting Interventions Improve Chronic Pain, Mood, Quality of Life, and Cognition in Patients with Mild Alzheimer's Disease? Evidence from a Randomized Controlled Trial.

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.

One-Year Evolution of Behavioral and Psychological Symptoms of Dementia in Patients Initially Hospitalized in Cognitive Behavioral Units: The EVITAL Prospective Cohort.

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.

Psychiatric manifestations of treatable hereditary metabolic disorders in adults.

Detecting psychiatric disorders of secondary origin is a crucial concern for the psychiatrist. But how can this reliably be done among a large number of conditions, most of which have a very low prevalence? Metabolic screening undertaken in a population of subjects with psychosis demonstrated the presence of treatable metabolic disorders in a significant number of cases. The nature of the symptoms that should alert the clinician is also a fundamental issue and is not limited to psychosis.
