A 57-year-old male with no family history was diagnosed with semantic dementia. He also showed some unusual cognitive features such as episodic memory and executive dysfunctions, spatial disorientation, and dyscalculia. Rapidly progressive cognitive and physical decline occurred. About 1.5 years later, he developed clinical features of a corticobasal syndrome. He died at the age of 60. Brain autopsy revealed numerous 4R-tau-positive lesions in the frontal, parietal and temporal lobes, basal ganglia, and brainstem. Neuronal loss was severe in the temporal cortex. Such association of semantic dementia with tauopathy and corticobasal syndrome is highly unusual. These findings are discussed in the light of current knowledge about frontotemporal lobar degeneration. [ABSTRACT FROM AUTHOR]

- Abstract
Supplemental digital content is available in the text.Weight gain is a major health problem among psychiatric populations. It implicates several receptors and hormones involved in energy balance and metabolism. Phosphoenolpyruvate carboxykinase 1 is a rate-controlling enzyme involved in gluconeogenesis, glyceroneogenesis and cataplerosis and has been related to obesity and diabetes phenotypes in animals and humans. The aim of this study was to investigate the association of phosphoenolpyruvate carboxykinase 1polymorphisms with metabolic traits in psychiatric patients treated with psychotropic drugs inducing weight gain and in general population samples. One polymorphism (rs11552145G > A) significantly associated with body mass index in the psychiatric discovery sample (n = 478) was replicated in 2 other psychiatric samples (n1= 168, n2= 188), with AA-genotype carriers having lower body mass index as compared to G-allelecarriers. Stronger associations were found among women younger than 45 years carrying AA-genotype as compared to G-allelecarriers (−2.25 kg/m2, n = 151, P= 0.009) and in the discovery sample (−2.20 kg/m2, n = 423, P= 0.0004). In the discovery sample for which metabolic parameters were available, AA-genotype showed lower waist circumference (−6.86 cm, P= 0.008) and triglycerides levels (−5.58 mg/100 mL, P< 0.002) when compared to G-allelecarriers. Finally, waist-to-hip ratio was associated with rs6070157(proxy of rs11552145, r2= 0.99) in a population-based sample (N = 123,865, P= 0.022). Our results suggest an association of rs11552145G > Apolymorphism with metabolic-related traits, especially in psychiatric populations and in women younger than 45 years.

- Abstract
Metabolic syndrome (MetS) associated with psychiatric disorders and psychotropic treatments represents a major health issue. 11-Hydroxysteroid dehydrogenase type 1 (11-HSD1) is an enzyme that catalyzes tissue regeneration of active cortisol from cortisone. Elevated enzymatic activity of 11-HSD1 may lead to the development of MetS.

IMPORTANCE: There is a high prevalence of obesity in psychiatric patients, possibly leading to metabolic complications and reducing life expectancy. The CREB-regulated transcription coactivator 1 (CRTC1) gene is involved in energy balance and obesity in animal models, but its role in human obesity is unknown. OBJECTIVE: To determine whether polymorphisms within the CRTC1 gene are associated with adiposity markers in psychiatric patients and the general population. DESIGN, SETTING, AND PARTICIPANTS: Retrospective and prospective data analysis and population-based samples at Lausanne and Geneva university hospitals in Switzerland and a private clinic in Lausanne, Switzerland. The effect of 3 CRTC1 polymorphisms on body mass index (BMI) and/or fat mass was investigated in a discovery cohort of psychiatric outpatients taking weight gain-inducing psychotropic drugs (sample 1, n = 152). The CRTC1 variant that was significantly associated with BMI and survived Bonferroni corrections for multiple comparison was then replicated in 2 independent psychiatric samples (sample 2, n = 174 and sample 3, n = 118) and 2 white population-based samples (sample 4, n = 5338 and sample 5, n = 123 865). INTERVENTION: Noninterventional studies. MAIN OUTCOME AND MEASURE: Difference in BMI and/or fat mass between CRTC1 genotype groups. RESULTS: Among the CRTC1 variants tested in the first psychiatric sample, only rs3746266A>G was associated with BMI (P
adjusted = .003). In the 3 psychiatric samples, carriers of the rs3746266 G allele had a lower BMI than noncarriers (AA genotype) (sample 1, P = .001; sample 2, P = .05; and sample 3, P = .0003). In the combined analysis, excluding patients taking other weight gain-inducing drugs, G allele carriers (n = 98) had a 1.81-kg/m² lower BMI than noncarriers (n = 226; P < .0001). The strongest association was observed in women younger than 45 years, with a 3.87-kg/m² lower BMI in G allele carriers (n = 25) compared with noncarriers (n = 48; P < .0001), explaining 9%of BMI variance. In the population-based samples, the T allele of rs6510997C>T (a proxy of the rs3746266 G allele; r2 = 0.7)was associated with lower BMI (sample 5, n = 123 865; P = .01) and fat mass (sample 4, n = 5338; P = .03). The strongest association with fat mass was observed in premenopausal women (n = 1192; P = .02). CONCLUSIONS AND RELEVANCE: These findings suggest that CRTC1 contributes to the genetics of human obesity in psychiatric patients and the general population. Identification of high-risk subjects could contribute to a better individualization of the pharmacological treatment in psychiatry. [ABSTRACT FROM AUTHOR]- Published

Abstract: Different factors influence ADL performance among nursing home (NH) residents in long term care. The aim was to investigate which factors were associated with a significant change of ADL performance in NH residents, and whether or not these factors were gender-specific. The design was a survival analysis. The 10,199 participants resided in ninety Swiss NHs. Their ADL performance had been assessed by the Resident Assessment Instrument Minimum Data Set (RAI-MDS) in the period from 1997 to 2007. Relevant change in ADL performance was defined as 2 levels of change on the ADL scale between two successive assessments. The occurrence of either an improvement or a degradation of the ADL status) was analyzed using the Cox proportional hazard model. The analysis included a total of 10,199 NH residents. Each resident received between 2 and 23 assessments. Poor balance, incontinence, impaired cognition, a low BMI, impaired vision, no daily contact with proxies, impaired hearing and the presence of depression were, by hierarchical order, significant risk factors for NH residents to experience a degradation of ADL performance. Residents, who were incontinent, cognitively impaired or had a high BMI were significantly less likely to improve their ADL abilities. Male residents with cancer were prone to see their ADL improve. The year of NH entry was significantly associated with either degradation or improvement of ADL performance. Measures aiming at improving balance and continence, promoting physical activity, providing appropriate nourishment and cognitive enhancement are important for ADL performance in NH residents.

The purpose of the present study was to probe sensitivity to potentially misleading negative feedback on cognitive tasks as a possible mechanism of cognitive impairment in elderly patients with mild depression. A total of 22 mildly depressed elderly subjects were compared to 22 healthy controls, using a computerized Tower-of-London task. Failure and magnitude of failure were significantly worse after negative but not positive feedback. Depression predicted failure after negative feedback but not the magnitude of failure. Neither failure nor magnitude of failure increased as a consequence of repeated negative feedback. Altered sensitivity to negative feedback occurs in mild late-life unipolar depression and may represent a subtle context-specific phenomenon. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: Previous studies reported that the severity of cognitive deficits in euthymic patients with bipolar disorder (BD) increases with the duration of illness and postulated that progressive neuronal loss or shrinkage and white matter changes may be at the origin of this phenomenon. To explore this issue, the authors performed a case-control study including detailed neuropsychological and magnetic resonance imaging analyses in 17 euthymic elderly patients with BD and 17 healthy individuals. Methods: Neuropsychological evaluation concerned working memory, episodic memory, processing speed, and executive functions. Volumetric estimates of the amygdala, bippocampus, entorhinal cortex, and anterior cingulate cortex were obtained using both voxel-based and region of interest morphometric methods. Periventricular and deep white matter were assessed semiquantitatively. Differences in cognitive performances and structural data between BD and comparison groups were analyzed using paired t-test or analysis of variance. Wilcoxon test was used in the absence of normal distribution. Results: Compared with healthy individuals, patients with BD obtained significantly lower performances in processing speed, working memory, and episodic memory but not in executive functions. Morphometric analyses did not show significant volumetric or white matter differences between the two groups. Conclusions: Our results revealed impairment in verbal memory, working memory, and processing speed in euthymic older adults with BD. These cognitive deficits are comparable both in terms of affected functions and size effects to those previously reported in younger cohorts with BD. Both this observation and the absence of structural brain abnormalities in our cohort do not support a progressively evolving neurotoxic effect in BD. [ABSTRACT FROM AUTHOR]

The progressive development of Alzheimer disease (AD)-related lesions, such as neurofibrillary tangles (NFT), amyloid deposits and synaptic loss, and the occurrence of microvascular and small macrovascular pathology within the cerebral cortex are conspicuous neuropathologic features of brain aging. Recent neuropathologic studies strongly suggested that the clinical diagnosis of dementia depends more on the severity and topography of pathological changes than on the presence of a qualitative marker. However, several methodological problems, such as selection biases, case–control design, density-based measures and masking effects, of concomitant pathologies persisted. In recent years, we performed several clinicopathologic studies using stereological counting of AD lesions. In order to define the cognitive impact of lacunes and microvascular lesions, we also analyzed pure vascular cases without substantial AD pathology. Our data revealed that total NFT numbers in the CA1 field, cortical microinfarcts and subcortical gray matter lacunes were the stronger determinants of dementia. In contrast, the contribution of periventricular and subcortical white matter demyelinations had a modest cognitive effect even in rare cases with isolated microvascular pathology. Importantly, in cases with pure AD pathology, more than 50% of Clinical Dementia Rating scale variability was not explained by NFT, amyloid deposits and neuronal loss in the hippocampal formation. In cases with microvascular pathology or lacunes, this percentage was even lower. The present review summarizes our data in this field and discusses their relevance within the theoretical framework of the functional neuropathology of brain aging and with particular reference to the current efforts to develop standardized neuropathological criteria for mixed dementia.

Background: In recent years, there has been a growing interest in the investigation of very old individuals. However, various challenges arise when collecting data from this age group. Given potential health and cognitive impairments and the difficulty of retrieving accurate self-reported data, involving individuals knowledgeable of the target person as proxy respondents are an invaluable solution. The primary goal of this study is to explore the association between proxy-centenarian relationship and item nonresponse, a pivotal data quality measure. Data and methods: We used data from the phone study conducted within SWISS100, a study on centenarians in Switzerland, focusing on a subsample of 94 centenarians and 75 proxy respondents. We compared characteristics of centenarians who provided self-reports with those interviewed through proxy respondents using descriptive analyses, and Firth's regression models to investigate the association of different types of proxies (children, other relatives, and non-relatives) with item nonresponse. Results: We noted differences between centenarians participating themselves in interviews and those represented by proxies, observing higher proportions of men and private home residents in the self-report group. There was a low prevalence of item nonresponse among proxy respondents. Proxy type significantly impacted item nonresponse, particularly with non-relatives showing notably higher unanswered question rates. A robust association between non-relatives as proxies and increased item nonresponse persisted even when controlling for potential confounding factors. Discussion and conclusions: This study enhances the understanding of data quality, particularly item nonresponse, and highlights the impact of the proxy-centenarian relationship when studying the oldest-old. The findings stress the importance of carefully choosing proxy respondents, preferably children, to improve data quality and inclusivity for those individuals hard to reach or to interview. Future research should investigate various data quality indicators and rely on larger samples to enhance the representation and methodological rigour in the study of the oldest-old.

• Fixation frequency and scanpath length increase with self-rated unpleasantness. • Fixation frequency and scanpath length increase with self-rated arousal. • Fixation frequency and scanpath length decrease within series of similar pictures. • The decrease in eye movements within series of similar pictures is age-dependent. • Women exhibit a more exploratory scanning behavior than men do. How top-down and bottom-up factors combine to determine eye movements during affective picture viewing is far from being completely understood. We investigated how observers' fixation frequency and scanpath length – two indices of information seeking and intake – are related to self-reported valence (pleasantness) and arousal and depend on gender, age, and repeated exposure during affective picture viewing. We tracked the eye movements of 157 younger, middle-aged, and older adults when viewing 14 picture series each consisting of six thematically and affectively similar pictures. Participants' valence and arousal ratings were registered for each series. Fixation frequency and scanpath length increased with self-rated unpleasantness and arousal and decreased across the six pictures within series. This decrease was age- and arousal-dependent. Compared to men, women exhibited a more exploratory scanning behavior. These findings suggest that observers' affective appraisal, gender and age and repeated exposure to affective visual stimuli influence visual information seeking and intake. [ABSTRACT FROM AUTHOR]

Introduction Optimal medication management is one of the basic conditions necessary for home-dwelling older adults living with multiple chronic conditions (OAMCC) to be able to remain at home and preserve their quality of life. Currently, the reasons for such high numbers of emergency department visits and the very significant rate of hospitalisations for OAMCC, due to medication-related problems (MRPs), is poorly explored. This study aims to reveal the current state of the medication management practices of polymedicated, home-dwelling OAMCC and to make proposals for improving clinical and medication pathways through an innovative and integrated model for supporting medication management and preventing adverse health outcomes. Methods and analysis A mixed-methods study will address the medication management of polymedicated, home-dwelling OAMCC. Its explanatory sequential design will involve two major phases conducted sequentially over time. The quantitative phase will consist of retrospectively exploiting the last 5 years of electronic patient records from a local hospital (N ≈ 50 000) in order to identify the different profiles—made up of patient-related, medication-related and environment-related factors—of the polymedicated, home-dwelling OAMCC at risk of hospitalisation, emergency department visits, hospital readmission (notably for MRPs), institutionalisation or early death. The qualitative study will involve: (a) obtaining and understanding the medication management practices and experiences of the identified profiles extracted from the hospital data of OAMCC who will be interviewed at home (N ≈ 30); (b) collecting and analysing the perspectives of the formal and informal caregivers involved in medication management at home in order to cross-reference perspectives about this important dimension of care at home. Finally, the mixed-methods findings will enable the development of an innovative, integrated model of medication management based on the Agency for Clinical Innovation framework and Bodenheimer and Sinsky’s quadruple aim. Ethics and dissemination Ethical approval has been obtained from the Human Research Ethics Committee of the Canton Vaud (2018-02196). Findings will be disseminated in peer-reviewed journals, professional conferences and other knowledge transfer activities with primary healthcare providers, hospital care units, informal caregivers’ and patients’ associations.

- Abstract
Background: Vocally disruptive behavior (VDB) in the elderly is a common condition, especially in people with dementia, but difficult to treat. It may occur in as many as 40% of nursing home residents. This study is a review of the existing literature on this condition. Method: The literature review was conducted using PubMed (particularly Medline and the Cochrane database) and reference lists from relevant publications in English, French, and German. Results: Most studies are small and no conclusive prevalence data are available. Many biological and psychosocial treatments have been advocated, but most studies are little more than anecdotal case reports. It is evident that VDB can have deleterious consequences on others and the patients themselves, although no studies specifically examine the range or the pervasiveness of VDB. Etiopathogenic research on VDB is still in its infancy. Conclusions: Most aspects surrounding VDB are insufficiently understood. The heterogeneity and multiple contributive factors regarding VDB suggest quite convincingly that a panoply of different interventions tailored to the individual's needs will be required to overcome VDB and the suffering related to it

- Abstract
With the increase in aging all over the world, and the elderly population nearly tripling from 524 million (8% of the world's population) in 2010 to 1.5 billion (16% of the world's population) in 2050, we will face new challenges and opportunities in providing healthcare. In 2050, it is estimated that Europe will see an increase of 70% in elderly population aged over 65 years, and 170% in those aged over 80 years (World Health Organization (WHO), 2011). It is vital to respond to the needs of this emerging population and the consequent rise in chronic diseases, especially dementia and mental health disorders, which will overload the healthcare system, as well as raise health and social costs, and demand new policies from national governments (World Health Organization, 2012). We urgently need to know how to organize healthcare for elderly people in the years to come

- Abstract
Background: Mild cognitive impairment (MCI) has been defined as a transitional state between normal aging and dementia. In many cases, MCI represents an early stage of developing cognitive impairment. Patients diagnosed with MCI do not meet the criteria for dementia as their general intellect and everyday activities are preserved, although minor changes in instrumental activities of daily living (ADL) may occur. However, they may exhibit significant behavioral and psychological signs and symptoms (BPS), also frequently observed in patients with Alzheimer's disease (AD). Hence, we wondered to what extent specific BPS are associated with cognitive decline in participants with MCI or AD. Methods: Our sample consisted of 164 participants, including 46 patients with amnestic (single or multi-domain) MCI and 54 patients with AD, as well as 64 control participants without cognitive disorders. Global cognitive performance, BPS, and ADL were assessed using validated clinical methods at baseline and at two-year follow-up. Results: The BPS variability over the follow-up period was more pronounced in the MCI group than in patients with AD: some BPS improve, others occur newly or worsen, while others still remain unchanged. Moreover, specific changes in BPS were associated with a rapid deterioration of the global cognitive level in MCI patients. In particular, an increase of euphoria, eating disorders, and aberrant motor behavior, as well as worsened sleep quality, predicted a decline in cognitive functioning. Conclusions: Our findings confirm a higher variability of BPS over time in the MCI group than in AD patients. Moreover, our results provide evidence of associations between specific BPS and cognitive decline in the MCI group that might suggest a risk of conversion of individuals with amnestic MCI to AD

Summary The aim of this study is to describe the patterns of prescription of benzodiazepine‐receptor agonists in hospitalised patients in four psychogeriatric units in Switzerland. This is a retrospective cross‐sectional study that included patients aged 65 years or more hospitalised in one of the four psychogeriatric units of a university hospital in Switzerland during 2019. The presence, type and dose of benzodiazepine‐receptor agonists was assessed at admission and at discharge. Three‐hundred and eighty‐six patients (214 women, 78.2 ± 8.1 years) were included in the study; 33.4% of patients had at least one benzodiazepine‐receptor agonist at admission and 22.5% at discharge. The relative reduction of benzodiazepine‐receptor agonists prescription in standardised dose was 78%. Age was found to be a protective factor against benzodiazepine‐receptor agonists prescription at admission (adjusted odds ratio 0.94, confidence interval 0.91–0.98), and diagnosis of substance abuse was found to be a risk factor (adjusted odds ratio 4.43, confidence interval 1.42–17.02). Longer hospital stays (> 14 days) were associated with higher reduction of benzodiazepine‐receptor agonists. The prevalence of a prescription of benzodiazepine‐receptor agonists at admission was high, but during the psychogeriatric hospitalisation benzodiazepine‐receptor agonists prescription decreased both in absolute and relative terms.

Weight gain, blood lipids and/or glucose dysregulation can follow aripiprazole treatment onset. Whether aripiprazole dosage is associated with an increase in these metabolic parameters remains uncertain. The present study investigates aripiprazole dose associations with weight change, blood glucose, lipids, and blood pressure. 422 patients taking aripiprazole for a minimum of three weeks to one year were selected from PsyMetab and PsyClin cohorts. Associations between aripiprazole dose and metabolic outcomes were examined using linear mixed-effect models. Aripiprazole dose was associated with weight change when considering its interaction with treatment duration (interaction term: −0.10, p < 0.001). This interaction resulted in greater weight gain for high versus low doses at the beginning of the treatment, this result being overturned at approximately five months, with greater weight increase for low versus high doses thereafter. LDL and HDL cholesterol levels were associated with aripiprazole dose over five months independently of treatment duration, with an average of 0.06 and 0.02 mmol/l increase for each 5 mg increment, respectively (p = 0.033 and p = 0.016, respectively). Furthermore, mean dose increases were associated with greater odds (+30 % per 5 mg increase) of clinically relevant weight gain (i.e., ≥7 %) over one year (p = 0.025). Aripiprazole dose was associated with one-year weight changes when considering its interaction with treatment duration. Increasing its dose could lead to metabolic worsening over the first five months of treatment, during which minimum effective doses should be particularly preferred. [ABSTRACT FROM AUTHOR]

Background: Neuropsychiatric symptoms (NPS) are common in older people, may occur early in the development of dementia disorders, and have been associated with faster cognitive decline. Here, our objectives were to investigate whether plasma levels of neurofilament light chain (NfL), glial fibrillary acid protein (GFAP), and tau phosphorylated at threonine 181 (pTau181) are associated with current NPS and predict future NPS in non-demented older people. Furthermore, we tested whether the presence of NPS combined with plasma biomarkers are useful to predict Alzheimer's disease (AD) pathology and cognitive decline. Methods: One hundred and fifty-one participants with normal cognition (n = 76) or mild cognitive impairment (n = 75) were examined in a longitudinal brain aging study at the Memory Centers, University Hospital of Lausanne, Switzerland. Plasma levels of NfL, GFAP, and pTau181 along with CSF biomarkers of AD pathology were measured at baseline. NPS were assessed through the Neuropsychiatric Inventory Questionnaire (NPI-Q), along with the cognitive and functional performance at baseline and follow-up (mean: 20 months). Different regression and ROC analyses were used to address the associations of interest. Results: None of the three plasma biomarker was associated with NPS at baseline. Higher GFAP levels were associated with the presence of NPS at follow-up (OR = 2.8, p =.002) and both, higher NfL and higher GFAP with an increase in the NPI-Q severity score over time (β = 0.25, p =.034 and β = 0.30, p =.013, respectively). Adding NPS and the plasma biomarkers to a reference model improved the prediction of future NPS (AUC 0.72 to 0.88, p =.002) and AD pathology (AUC 0.78 to 0.87, p =.010), but not of cognitive decline (AUC 0.79 to 0.85, p =.081). Conclusion: Plasma NfL and GFAP are both associated with future NPS and NPS severity change. Considering the presence of NPS along with blood-based AD-biomarkers may improve the prediction of clinical progression of NPS over time and inform clinical decision-making in non-demented older people.

Background: Given the increasing number of people achieving exceptionally long lifespans, there is an urgent need for a better understanding of mental health in centenarians. This study aimed to understand the prevalence of mental health conditions—depressive symptoms, anxiety, sleep disturbances, disinhibition, and aberrant motor behaviour—among centenarians in Switzerland. Methods: Data were collected from N = 169 participants via telephone interviews or paper questionnaires, either directly from centenarians or through proxy informants. Half the data were collected during a period when protective measures were imposed due to the COVID‐19 pandemic, and half were collected after the measures were lifted. Results: Mental health conditions were prevalent in our sample, particularly depressive symptoms (44.51%) and anxiety (42.17%). Significant positive associations were found between depressive symptoms and anxiety, and between disinhibition and aberrant motor behaviour. Furthermore, we identified statistical predictors for the occurrence of mental health conditions. Notably, institutionalised living increased the odds of depressive symptomatology, while those with higher education levels or an absence of cognitive impairment experienced more sleep disturbances. Finally, cognitive impairment was linked to increased disinhibition and aberrant motor behaviour. Conclusions: The high prevalence of mental health conditions underscores the need for proactive mental health care strategies in advanced old age. Moreover, it is vital to consider the interconnected nature of mental health conditions and to prioritise vulnerable groups, such as centenarians in institutional settings. [ABSTRACT FROM AUTHOR]

Elevated cortisol levels have been associated with poorer cognitive performance in cross-sectional studies; this may be both a factor contributing to neurodegeneration and cognitive decline and a result of developing brain pathologies. However, it is still unclear (1) whether cortisol measures predict later cognitive decline and (2) whether cortisol changes over the years might be associated with cognitive changes. We analyzed data from CoLaus/PsyCoLaus, a prospective population-based study. Salivary cortisol (4 different measures on 1 day) and neuropsychological assessments were performed at a first visit and a follow-up visit 5 years later in 625 dementia-free participants aged ≥65 years. Salivary cortisol levels at waking and 30 minutes after waking, as well as longitudinal changes in cortisol 30 minutes after waking, cortisol awakening response, and cortisol AM-PM difference were associated with decline in global cognition. After controlling for potential confounders, only longitudinal changes in cortisol 30 minutes after waking remained associated with cognitive decline. These mostly negative findings indicate absent or subtle association between salivary cortisol and cognitive decline. [ABSTRACT FROM AUTHOR]

Background: Metabolic side effects of psychotropic medications are a major drawback to patients' successful treatment. Using an epigenome-wide approach, we aimed to investigate DNA methylation changes occurring secondary to psychotropic treatment and evaluate associations between 1-month metabolic changes and both baseline and 1-month changes in DNA methylation levels. Seventy-nine patients starting a weight gain inducing psychotropic treatment were selected from the PsyMetab study cohort. Epigenome-wide DNA methylation was measured at baseline and after 1 month of treatment, using the Illumina Methylation EPIC BeadChip. Results: A global methylation increase was noted after the first month of treatment, which was more pronounced (p < 2.2 × 10–16) in patients whose weight remained stable (< 2.5% weight increase). Epigenome-wide significant methylation changes (p < 9 × 10−8) were observed at 52 loci in the whole cohort. When restricting the analysis to patients who underwent important early weight gain (≥ 5% weight increase), one locus (cg12209987) showed a significant increase in methylation levels (p = 3.8 × 10–8), which was also associated with increased weight gain in the whole cohort (p = 0.004). Epigenome-wide association analyses failed to identify a significant link between metabolic changes and methylation data. Nevertheless, among the strongest associations, a potential causal effect of the baseline methylation level of cg11622362 on glycemia was revealed by a two-sample Mendelian randomization analysis (n = 3841 for instrument-exposure association; n = 314,916 for instrument-outcome association). Conclusion: These findings provide new insights into the mechanisms of psychotropic drug-induced weight gain, revealing important epigenetic alterations upon treatment, some of which may play a mediatory role.

SUMMARY: Research on the relationship between obstructive sleep apnea and cognitive functioning has yielded conflicting results, particularly in the older population, and moderators of this association have rarely been studied. Here we investigated the cross‐sectional association between obstructive sleep apnea and cognitive functioning as well as the moderating effect of age, sex, apolipoprotein E4, and obesity on this association among community‐dwelling older people. We analysed data from 496 participants (71.4 ± 4.4 years; 45.6% men) of the HypnoLaus study who underwent polysomnography and a battery of neuropsychological tests. The sample was categorised as no‐to‐mild obstructive sleep apnea (apnea–hypopnea index 0–14.9/h; reference), moderate obstructive sleep apnea (apnea–hypopnea index 15.0–29.9/h), or severe obstructive sleep apnea (apnea–hypopnea index ≥30/h). Regression and moderation analyses were performed with adjustment for confounders. Apolipoprotein E4 and obesity moderated the association between severe obstructive sleep apnea and processing speed, whereas no moderating effects were found for age and sex. In apolipoprotein E4 carriers only, severe obstructive sleep apnea was associated with lower performance in Stroop condition 1 (B = 3.13, p = 0.024). In obese participants only, severe obstructive sleep apnea was associated with lower performance in Stroop condition 1 (B = 3.02, p = 0.025) and Stroop condition 2 (B = 3.30, p = 0.034). Severe obstructive sleep apnea was also associated with lower executive function in the whole sample according to Stroop condition 3 (B = 3.44, p = 0.020) and Stroop interference score (B = 0.24, p = 0.006). Our findings support associations of severe obstructive sleep apnea (but not moderate obstructive sleep apnea) with lower performance in processing speed and executive function in the older general population. Apolipoprotein E4 and obesity appear to be vulnerability factors that strengthen the association between severe obstructive sleep apnea and lower performance in processing speed.

The current evidence of a relationship between periodic leg movements during sleep (PLMS) and cognitive functioning is limited and inconsistent. This cross-sectional study assessed associations between PLMS and cognitive functioning among community-dwelling older adults. We included community-dwelling older adults who underwent a polysomnography and a cognitive assessment. The PLMS index (PLMI) and PLMS arousal index (PLMAI) were categorized into tertiles: PLMI <5/h (reference), 5–29.9/h, ≥30/h; and PLMAI <1/h (reference), 1–4.9/h, ≥5/h. The cognitive assessment consisted of ten scores covering the main cognitive domains: global cognition, processing speed, executive function, language, episodic verbal memory, and visuospatial function. Associations between PLMI, PLMAI, and cognitive scores were assessed using regression unadjusted and adjusted models. A total of 579 individuals without dementia were included (mean age: 71.5 ± 4.4 years; men 45.4%). The number of participants in the high-PLMI categories, 5–29.9/h and ≥30/h, was 185 (32.0%) and 171 (29.5%), respectively. Participants in the high-PLMI categories showed no significant difference compared to the reference group regarding their cognitive performance according to the unadjusted and adjusted models. Similarly, we found no association between PLMAI severity and cognitive functioning. This study shows no cross-sectional association between PLMS severity and cognitive functioning among community-dwelling older adults. However, given the paucity of data in this field, further studies are needed to clarify the relationship between PLMS and cognitive functioning. • Little is known about the link between PLMS and cognition. • We tested associations between PLMS and cognition in community-dwelling older adults. • In this cross-sectional study, PLMS were not associated with cognitive functioning. • Further studies are needed to clarify the potential link between PLMS and cognition.

We analyzed the psychometric properties of the Structured Interview for the Five-Factor Model (SIFFM) in a French-speaking Swiss sample and compared the French version to the original English version. A community-based sample of 260 participants (183 women and 77 men, aged 20 to 88 years, Mage = 46.23, SDage = 16.37) were assessed using the SIFFM and the NEO-FFI-R. Forty of the participants agreed to be filmed or to be assessed by two investigators simultaneously. The internal consistency coefficients of the five dimensions of SIFFM ranged from .63 to .84. Anexploratory factor analysis within the confirmatory factor analysis framework showed that the structure of the French version of the SIFFM was in line with the structure suggested by the Five-Factor Model. Except for the modesty and dutifulness subscales, each facet scale had its highest factor loading on the factor representing the targeted domain. Moreover, a principal axis joint factor analysis of the SIFFM and NEO-FFI-R domains suggested that the convergent validity between the two instruments was adequate. Furthermore, the interrater reliability coefficients for the SIFFM scores were high. The French version of the SIFFM shows acceptable psychometric properties, comparable to those of the English version, and may be an informative assessment method and an alternative to self-report measures.

Abstract: Employing a naturalistic multiple case study approach, we investigated the current clinical practice in the treatment and care of VDB among a convenience sample of 85 patients cared for in specialized old age psychiatric clinics and nursing homes in French and German-speaking Switzerland. We wished to clinically characterize VDB patients, to identify common approaches used to treat VDB in everyday practice, and to explore how the efficiency of the interventions employed was judged by the responsible carers. Data were collected by means of a questionnaire. Most patients with VDB in this study had dementia, of whom 75% had at least one current or premorbid psychiatric disorder and 25% had premorbid personality disorder. A majority of patients received multiple psychosocial care interventions that were often judged to be effective, but the potential of psychosocial interventions is underused. Many patients did not receive psychotropic medication specifically targeted at VDB, but about 70% of all prescriptions were judged to have positive effects. Premorbid psychiatric and personality disorders or traits are likely candidates to be entered into the etiopathogenic equation of VDB and set a new frame for approaches used to treat these underlying disorders.

Objective: Childhood maltreatment is associated with late-life depression. Preliminary evidence indicates that personality characteristics, in particular neuroticism and extroversion, and an anxious attachment style mediate this association. The objective is to evaluate 3 models, in which personality and attachment are considered mediators between childhood maltreatment and late-life depression in a socioeconomically disadvantaged Brazilian population. Methods: This study included participants (n = 260) from socioeconomically disadvantaged neighborhoods of Porto Alegre, Brazil, who completed measures of childhood maltreatment (Childhood Trauma Questionnaire – CTQ), personality characteristics (NEO-Five Factor Inventory), attachment styles (Relationship Scales Questionnaire), and geriatric depression (Mini-International Neuropsychiatric Interview-Plus). General multiple and sequential mediation analyses were used to test for possible associations. Results: Attachment anxiety but not attachment avoidance is a mediator between childhood maltreatment and geriatric depression. Neuroticism is a full mediator. At that, attachment anxiety was found to be a predictor of neuroticism. Finally, sequential mediation analysis shows a path from childhood maltreatment to geriatric depression through attachment anxiety and neuroticism. Conclusions: The results suggest a pathway from childhood maltreatment to anxious attachment, which in turn predicts higher neuroticism that itself may favor late-life depression. This hypothesis could have implications for older adults living in low socioeconomic settings in that treating the high-risk group of maltreated children may help prevent late-life depression.

Background The clinical courses of psychogeriatric inpatients presenting behavioral and psychological symptoms of dementia, between their admission and discharge, have been poorly documented. Based upon our previously elaborated profiles of psychogeriatric patients, this study aimed to describe these courses and to explore whether changing clinical profiles could predict living arrangements at discharge. Methods Retrospective data were collected on 397 patients with dementia and hospitalized from 2011 to 2014 in French-speaking Switzerland. Patients were classified on admission and at discharge using four clinical profiles ( BPSD-affective , BPSD-functional , BPSD-somatic , and BPSD-psychotic ). Multinomial logistic regression analyses were used to identify predictors of living arrangements at discharge. Age, gender, marital status, living arrangements on admission, and clinical profile on admission and discharge, were used as potential predictors. Results Of the patients classified as BPSD-functional or BPSD-affective on admission, 70.18% and 73.48%, respectively, had the same classification at discharge. However, 45.74% of patients classified as BPSD-somatic on admission were discharged with a BPSD-functional profile, and 46.15% of inpatients classified as BPSD-psychotic on admission were discharged as BPSD-affective (χ 2 (9) = 128.8299; p < 0.000). At discharge, 64.99% of all patients were admitted to a nursing home. The significant predictors of return to home were: being male (OR = 0.96; 95% CI: 0.93–0.99) and BPSD-affective profile (OR = 1.95; 95% CI: 1.08–3.54. Significant predictors of transfer to acute care or death were: BPSD-somatic (OR = 12.98; 95% CI: 1.96–85.91) or BPSD-psychotic profile (OR = 13.53; 95% CI: 1.65–111.05). Discussion This study provides new information concerning the clinical course of older psychogeriatric inpatients using profiles derived from clinically sensitive profiles. [ABSTRACT FROM AUTHOR]

The wish to die (WTD) in persons near the end of life is a clinically important, ethically and practically complex phenomenon as demonstrated by the intense debates on assisted dying legislation around the world. Despite global aging and increasing institutionalization in old age, WTD among residents of long-term care facilities (LTCF) is underexplored. We aimed to assess the prevalence of WTD and identify its predictors in older LTCF residents. Multisite cross-sectional observational study. 31 LTCF in the 3 major linguistic regions of Switzerland, including residents 75 years or older, admitted to the LTCF 4 to 10 months before the study, without severe cognitive impairment. Between February 2013 and June 2017, trained research staff interviewed residents to assess WTD using 2 validated instruments and collected information on potential predictors, including depressive symptoms, anxiety, demoralization, feeling to be a burden, spiritual distress, symptom burden, multimorbidity, and drug use. Demographic data were obtained by chart review. Descriptive statistics as well as univariate and multivariate regression analyses were performed. From 427 eligible residents, 101 were excluded, 46 refused, and 280 were included in the study (acceptance rate 85.9%). In general, residents readily and openly addressed the topic of WTD. The prevalence of WTD was 16.0% and 16.2% according to the 2 instruments, with all but 1 of the residents expressing a passive WTD. The strongest independent predictors for a WTD were depressive symptoms (OR 7.45 and 5.77 for the 2 WTD assessment instruments) and demoralization (OR 2.62 and 3.66). The WTD is a relevant concern affecting approximately 1 in 6 LTCF residents. Further research is needed to investigate which interventions could best address the potentially modifiable factors that were associated with the WTD in this specific setting and population.

Study objectives: Insomnia disorders as well as cardiometabolic disorders are highly prevalent in the psychiatric population compared to the general population. We aimed to investigate their association and evolution over time in a Swiss psychiatric cohort. Methods: Data for 2861 patients (8954 observations) were obtained from two prospective cohorts (PsyMetab and PsyClin) with metabolic parameters monitored routinely during psychotropic treatment. Insomnia disorders were based on the presence of ICD-10 "F51.0" diagnosis (non-organic insomnia), the prescription of sedatives before bedtime or the discharge letter. Metabolic syndrome was defined using the International Diabetes Federation definition, while the 10-year risk of cardiovascular event or death was assessed using the Framingham Risk Score and the Systematic Coronary Risk Estimation, respectively. Results: Insomnia disorders were observed in 30% of the cohort, who were older, predominantly female, used more psychotropic drugs carrying risk of high weight gain (olanzapine, clozapine, valproate) and were more prone to suffer from schizoaffective or bipolar disorders. Multivariate analyses showed that patients with high body mass index (OR = 2.02, 95%CI [1.51–2.72] for each ten-kg/m2 increase), central obesity (OR = 2.20, [1.63–2.96]), hypertension (OR = 1.86, [1.23–2.81]), hyperglycemia (OR = 3.70, [2.16–6.33]), high density lipoprotein hypocholesterolemia in women (OR = 1.51, [1.17–1.95]), metabolic syndrome (OR = 1.84, [1.16–2.92]) and higher 10-year risk of death from cardiovascular diseases (OR = 1.34, [1.17–1.53]) were more likely to have insomnia disorders. Time and insomnia disorders were associated with a deterioration of cardiometabolic parameters. Conclusions: Insomnia disorders are significantly associated with metabolic worsening and risk of death from cardiovascular diseases in psychiatric patients. [ABSTRACT FROM AUTHOR]

Abstract: Brain aging is characterized by the formation of neurofibrillary tangles (NFT) and senile plaques (SP) in both cognitively intact individuals and patients with Alzheimer''s disease (AD). The ubiquitous presence of these lesions and the steady increase of the prevalence of dementia up to 85 years have strongly supported a continuum between normal brain aging and AD. In this context, the study of nonagenarians and centenarians could provide key informations about the characteristics of extreme aging. We provide here a detailed review of currently available neuropathological data in very old individuals and critically discuss the patterns of NFT, SP and neuronal loss distribution as a function of age. In younger cohorts, NFTs are usually restricted to hippocampal formation, whereas clinical signs of dementia appear when temporal neocortex is involved. SPs would not be a specific marker of cognitive impairment as no correlation was found between their quantitative distribution and AD severity. The low rate of AD lesions even in severe AD as well as the weakness of clinicopathological correlations reported in the oldest-old indicate that AD pathology is not a mandatory phenomenon of increasing chronological age. Our recent stereological observations of hippocampal microvasculature in oldest-old cases challenge the traditional lesional model by revealing that mean capillary diameters is an important structural determinant of cognition in this age group.
