Wisdom is a personality trait comprising seven components: self-reflection, pro-social behaviors, emotional regulation, acceptance of diverse perspectives, decisiveness, social advising, and spirituality. Wisdom, a potentially modifiable trait, is strongly associated with well-being. We have published a validated 28-item San Diego Wisdom Scale, the SD-WISE-28. Brief scales are necessary for use in large population-based studies and in clinical practice. The present study aimed to create an abbreviated 7-item version of the SD-WISE.

Participants included 2093 people, aged 20-82 years, recruited and surveyed through the online crowdsourcing platform Amazon Mechanical Turk. The participants’ mean age was 46 years, with 55% women. Participants completed the SD-WISE-28 as well as validation scales for various positive and negative constructs. Psychometric analyses (factor analysis and item response theory) were used to select one item from each of the seven SD-WISE-28 subscales.

We selected a combination of items that produced acceptable unidimensional model fit and good reliability (ω = 0.74). Item statistics suggested that all seven items were strong indicators of wisdom, although the association was weakest for spirituality. Analyses indicated that the 28-item and 7-item SD-WISE are both very highly correlated (r = 0.92) and produce a nearly identical pattern of correlations with demographic and validity variables.

The SD-WISE-7, and its derived Jeste-Thomas Wisdom Index (JTWI) score, balances reliability and brevity for research applications.

The primary aim was to systematically review the literature regarding the effectiveness of clozapine in reducing symptoms of primary psychotic and bipolar disorders in older adults. The secondary aim was to describe other reported patient and caregiver outcomes of clozapine treatment in older adults.

MEDLINE, Embase, PsychINFO, ProQuest, and PubMed databases were searched according to PRISMA guidelines for original empirical research examining the effectiveness of clozapine in adults aged 65 years or more with primary psychotic and bipolar disorders. Identified studies were assessed for methodological quality using the QualSyst tool.

1121 records were screened, of which 7 studies met the inclusion criteria. In total, 128 subjects participated in the included studies (111 of whom were from a single study), with an age range of 65–86 years, and diagnoses including schizophrenia, schizoaffective disorder, bipolar disorder, and delusional disorder. Indications for clozapine use included treatment resistance and inability to tolerate other treatments. While six out of seven studies reported some improvement on the primary measure of psychopathology after treatment with clozapine, the group effects were modest and based on low-level evidence. Additional reported outcomes included discharge destination, death, and relapse. Most of the included studies were only of adequate methodological quality, with significant risks of bias identified.

Clozapine may have positive effects for primary psychotic and bipolar illnesses in some older adults, but the group effects reported were modest and based on low-level evidence studies with methodological limitations. Based on these findings, clinical decision-making about whether or not to trial clozapine should involve an individualized analysis of potential benefits and risks in collaboration with patients and their families and caregivers.

To perform a meta-analysis of clinical studies on the differences in treatment or research decision-making capacity among patients with Mild Cognitive Impairment (MCI), Alzheimer’s disease (AD), and healthy comparisons (HCs).

A systematic search was conducted on Medline/Pubmed, CINAHL, PsycINFO, Web of Science, and Scopus. Standardized mean differences and random-effects model were used in all cases.

The United States, France, Japan, and China.

Four hundred and ten patients with MCI, 149 with AD, and 368 HCs were included.

The studies we included in the analysis assessed decisional capacity to consent by the MacArthur Competence Assessment Tool for Treatment (MAcCAT-T), MacArthur Competence Assessment Tool for Clinical Research (MacCAT-CR), Capacity to Consent to Treatment Instrument (CCTI), and University of California Brief Assessment of Capacity to Consent (UBACC).

We identified 109 potentially eligible studies from 1672 records, and 7 papers were included in the meta-analysis. The meta-analysis showed that there was significant impairment in a decision-making capacity in MCI patients compared to the HCs group in terms of Understanding (SMD = −1.04, 95% CI: −1.31 to −0.77, P < 0.001; I2 = 52%, P = 0.07), Appreciation (SMD = −0.51, 95% CI: −0.66 to −0.36, P < 0.001; I2 = 0%, P = 0.97), and Reasoning (SMD = −0.62, 95% CI: −0.77, −0.47, P < 0.001; I2=0%, P =0.46). MCI patients scored significantly higher in Understanding (SMD = 1.50, 95% CI: 0.91, 2.09, P = 0.01, I2 = 78%, P = 0.00001) compared to patients affected by AD.

Patients affected by MCI are at higher risk of impaired capacity to consent to treatment and research compared to HCs, despite being at lower risk compared to patients affected by AD. Clinicians and researchers need to carefully evaluate decisional capacity in MCI patients providing informed consent.

Work in occupations with higher levels of occupational stress can bring mental health costs. Many older adults worldwide are continuing to work past traditional retirement age, raising the question whether older adults experience depression, anxiety, or burnout at the same or greater levels as younger workers, and whether there are differences by age in these levels over time.

Longitudinal survey of 1161 currently employed US clergy followed every 6–12 months for up to 66 months.

Depression was measured with the 8-item Patient Health Questionnaire (PHQ-8). Anxiety was measured using the anxiety component of the Hospital Anxiety and Depression Scale (HADS). Burnout symptoms were assessed using the three components of the Maslach Burnout Inventory: emotional exhaustion (EE), depersonalization (DP), and sense of personal accomplishment (PA).

Older participants had lower scores of depression, anxiety, EE, and DP and higher levels of PA over time compared to younger adults. Levels of EE decreased for older working adults, while not significantly changing over time for those younger. DP symptoms decreased over time among those 55 years or older but increased among those 25–54 years.

Older working adults may have higher levels of resilience and be able to balance personal life with their occupation as well as may engage in certain behaviors that increase social support and, for clergy, spiritual well-being that may decrease stress in a way that allows these older adults to appear to tolerate working longer without poorer mental health outcomes.

Patients with geriatric depression exhibit a spectrum of symptoms ranging from mild to severe cognitive impairment which could potentially lead to the development of Alzheimer’s disease (AD). The aim of the study is to assess the alterations of the default mode network (DMN) in remitted geriatric depression (RGD) patients and whether it could serve as an underlying neuropathological mechanism associated with the risk of progression of AD.

Cross-sectional study.

A total of 154 participants, comprising 66 RGD subjects (which included 27 patients with comorbid amnestic mild cognitive impairment [aMCI] and 39 without aMCI [RGD]), 45 aMCI subjects without a history of depression (aMCI), and 43 matched healthy comparisons (HC), were recruited.

All participants completed neuropsychological tests and underwent resting-state functional magnetic resonance imaging (fMRI). Posterior cingulate cortex (PCC)-seeded DMN functional connectivity (FC) along with cognitive function were compared among the four groups, and correlation analyses were conducted.

In contrast to HC, RGD, aMCI, and RGD-aMCI subjects showed significant impairment across all domains of cognitive functions except for attention. Furthermore, compared with HC, there was a similar and significant decrease in PCC-seed FC in the bilateral medial superior frontal gyrus (M-SFG) in the RGD, aMCI, and RGD-aMCI groups.

The aberrations in rsFC of the DMN were associated with cognitive deficits in RGD patients and might potentially reflect an underlying neuropathological mechanism for the increased risk of developing AD. Therefore, altered connectivity in the DMN could serve as a potential neural marker for the conversion of geriatric depression to AD.

To examine if smaller size at birth, an indicator of growth restriction in utero, is associated with lower cognition in late life, and whether this may be mediated by impaired early life brain development and/or adverse cardiometabolic programming.

Longitudinal follow-up of a birth cohort.

CSI Holdsworth Memorial Hospital (HMH), Mysore South India.

721 men and women (55–80 years) whose size at birth was recorded at HMH. Approximately 20 years earlier, a subset (n = 522) of them had assessments for cardiometabolic disorders in mid-life.

Standardized measurement of cognitive function, depression, sociodemographic, and lifestyle factors; blood tests and assessments for cardiometabolic disorders

Participants who were heavier at birth had higher composite cognitive scores (0.12 SD per SD birth weight [95% CI 0.05, 0.19] p = 0.001) in late life. Other lifecourse factors independently positively related to cognition were maternal educational level and participants’ own educational level, adult leg length, body mass index, and socioeconomic position, and negatively were diabetes in mid-life and current depression and stroke. The association of birth weight with cognition was independent cardiometabolic risk factors and was attenuated after adjustment for all lifecourse factors (0.08 SD per SD birth weight [95% CI −0.01, 0.18] p = 0.07).

The findings are consistent with positive effects of early life environmental factors (better fetal growth, education, and childhood socioeconomic status) on brain development resulting in greater long-term cognitive function. The results do not support a pathway linking poorer fetal development with reduced late life cognitive function through cardiometabolic programming.

Rates of suicide in older adults may be higher than reported due to poor understandings of presentation of suicide ideation in this group. The objectives of this paper were to (i) review current measurement tools designed for older adults to detect suicide ideation and (ii) assess their psychometric properties.

We used a systematic review approach to identify measurement tools developed specifically for older adults without cognitive decline or impairment.

Ten articles that reported on a total of seven different measurement tools were identified. These included tools that focused on resiliency to suicide and those that measured risk of suicide behavior. There was wide variation across the articles: some were adaptations of existing scales to suit older populations, others were developed by authors; they varied in length from four to 69 items; a range of settings was used, and there was a mix of self-report and clinician-administered measures. Most displayed good psychometric properties, with both approaches showing similar quality. Limitations in terms of samples, settings, and measurement design are discussed.

The case for specific measures for older adults is clear from this review. There appear to be unique factors that should be considered in understanding suicide ideation and behavior among older adults that may not be directly assessed in non-specific measurements. However, there is a need to expand the diversity of individuals included in measurement development to ensure they are appropriate across gender, culture and minority status, and for the views of professionals to be considered.

The Cognitive Abilities Screening Instrument (CASI) is a screening test of global cognitive function used in research and clinical settings. However, the CASI was developed using face validity and has not been investigated via empirical tests such as factor analyses. Thus, we aimed to develop and test a parsimonious conceptualization of the CASI rooted in cognitive aging literature reflective of crystallized and fluid abilities.

Secondary data analysis implementing confirmatory factor analyses where we tested the proposed two-factor solution, an alternate one-factor solution, and conducted a χ2 difference test to determine which model had a significantly better fit.

N/A.

Data came from 3,491 men from the Kuakini Honolulu-Asia Aging Study.

The Cognitive Abilities Screening Instrument.

Findings demonstrated that both models fit the data; however, the two-factor model had a significantly better fit than the one-factor model. Criterion validity tests indicated that participant age was negatively associated with both factors and that education was positively associated with both factors. Further tests demonstrated that fluid abilities were significantly and negatively associated with a later-life dementia diagnosis.

We encourage investigators to use the two-factor model of the CASI as it could shed light on underlying cognitive processes, which may be more informative than using a global measure of cognition.

We aimed to evaluate the prevalence, clinical determinants, and consequences (falls and hospitalization) of frailty in older adults with mental illness.

Retrospective clinical cohort study.

We collected the data in a specialized psychogeriatric ward, in Boston, USA, between July 2018 and June 2019.

Two hundred and fourty-four inpatients aged 65 years old and over.

Psychiatric diagnosis was based on a multi-professional consensus meeting according to DSM-5 criteria. Frailty was assessed according to two common instruments, that is, the FRAIL questionnaire and the deficit accumulation model (aka Frailty Index [FI]). Multiple linear regression analyses were conducted to evaluate the association between frailty and sample demographics (age, female sex, and non-Caucasian ethnicity) and clinical characteristics (dementia, number of clinical diseases, current infection, number of psychotropic, and non-psychotropic medications in use). Multiple regression between frailty assessments and either falls or number of hospital admissions in the last 6 and 12 months, respectively, were analyzed and adjusted for covariates.

Prevalence of frailty was high, that is, 83.6% according to the FI and 55.3% according to the FRAIL questionnaire. Age, the number of clinical (somatic) diseases, and the number of non-psychotropic medications were independently associated with frailty identified by the FRAIL. Dementia, current infection, the number of clinical (somatic) diseases, and the number of non-psychotropic medications were independently associated with frailty according to the FI. Falls were significantly associated with both frailty instruments. However, we found only a significant association for the number of hospital admissions with the FI.

Frailty is highly prevalent among geriatric psychiatry inpatients. The FRAIL questionnaire and the FI may capture different forms of frailty dimensions, being the former probably more associated with the phenotype model and the latter more associated with multimorbidity.

We examined differences across three groups in Israel to test the double jeopardy versus the intersection escape hypotheses-which evaluate whether being older and belonging to an underrepresented group serves as a double burden, exposing older minorities to higher levels of perceived ageism or on the contrary, older age serves as a protective factor, especially for underrepresented groups.

A cross-sectional, nationally representative sample, consisting of three groups: Veteran Israelis, Israeli Arabs and immigrants from the Former Soviet Union. The latter two groups represent underrepresented (minority) populations in Israel.

Community-dwelling Israelis over the age of 50.

The sample was composed of 1570 participants.

To examine the double jeopardy versus the intersectional escape hypothesis, self-perceptions of aging (SPA) and perceived age-based discrimination in the healthcare system were examined as outcome variables.

Among Israeli Arabs, being older was related to better SPA, whereas among the immigrants being older was related to worse SPA. As immigrants became older, they were more likely to report ageist experiences. Israeli Arabs reported higher levels of ageist experiences, regardless of their age.

The findings point to certain groups that require education about ageism and the aging processes and might require further protection from the experiences of ageism. The findings also point to the relevance of different theoretical paradigms that advocate for the consideration of culture and group membership in the understanding of the experiences of ageism.

To investigate global and momentary effects of a tablet-based non-pharmacological intervention for nursing home residents living with dementia.

Cluster-randomized controlled trial.

Ten nursing homes in Germany were randomly allocated to the tablet-based intervention (TBI, 5 units) or conventional activity sessions (CAS, 5 units).

N = 162 residents with dementia.

Participants received regular TBI (n = 80) with stimulating activities developed to engage people with dementia or CAS (n = 82) for 8 weeks.

Apathy Evaluation Scale (AES-I, primary outcome), Quality of Life in Alzheimer’s Disease scale, QUALIDEM scale, Neuropsychiatric Inventory, Geriatric Depression Scale, and psychotropic medication (secondary outcomes). Momentary quality of life was assessed before and after each activity session. Participants and staff were blinded until the collection of baseline data was completed. Data were analyzed with linear mixed-effects models.

Levels of apathy decreased slightly in both groups (mean decrease in AES-I of .61 points, 95% CI −3.54, 2.33 for TBI and .36 points, 95% CI −3.27, 2.55 for CAS). Group difference in change of apathy was not statistically significant (β = .25; 95% CI 3.89, 4.38, p = .91). This corresponds to a standardized effect size (Cohen’s d) of .02. A reduction of psychotropic medication was found for TBI compared to CAS. Further analyses revealed a post-intervention improvement in QUALIDEM scores across both groups and short-term improvements of momentary quality of life in the CAS group.

Our findings suggest that interventions involving tailored activities have a beneficial impact on global and momentary quality of life in nursing home residents with dementia. Although we found no clear advantage of TBI compared to CAS, tablet computers can support delivery of non-pharmacological interventions in nursing homes and facilitate regular assessments of fluctuating momentary states.

(1) To investigate if gut microbiota can be a predictor of remission in geriatric depression and to identify features of the gut microbiota that is associated with remission. (2) To determine if changes in gut microbiota occur with remission in geriatric depression.

Secondary analysis of a parent randomized placebo-controlled trial (NCT02466958).

Los Angeles, CA, USA (2016-2018)

Seventeen subjects with major depressive disorder, over 60 years of age, 41.2% female.

Levomilacipran (LVM) or placebo.

Remission was defined by Hamilton Depression Rating Scale score of 6 or less at 12 weeks. 16S-ribosomal RNA sequencing based fecal microbiota composition and diversity were measured at baseline and 12 weeks. Differences in fecal microbiota were evaluated between remitters and non-remitters as well as between baseline and post-treatment samples. LVM and placebo groups were combined in all the analyses.

Baseline microbiota showed no community level α-diversity or β-diversity differences between remitters and non-remitters. At the individual taxa level, a random forest classifier created with nine genera from the baseline microbiota was highly accurate in predicting remission (AUC = .857). Of these, baseline enrichment of Faecalibacterium, Agathobacter and Roseburia relative to a reference frame was associated with treatment outcome of remission. Differential abundance analysis revealed significant genus level changes from baseline to post-treatment in remitters, but not in non-remitters.

This is the first study demonstrating fecal microbiota as a potential predictor of treatment response in geriatric depression. Our findings need to be confirmed in larger prospective studies.

The relationship between wisdom and fluid intelligence (Gf) is poorly understood, particularly in older adults. We empirically tested the magnitude of the correlation between wisdom and Gf to help determine the extent of overlap between these two constructs.

Cross-sectional study with preregistered hypotheses and well-powered analytic plan (https://osf.io/h3pjx).

Memory and Aging Center at the University of California San Francisco, located in the USA.

141 healthy older adults (mean age = 76 years; 56% female).

Wisdom was quantified using a well-validated self-report-based scale (San Diego Wisdom Scale or SD-WISE). Gf was assessed via composite measures of processing speed (Gf-PS) and executive functioning (Gf-EF). The relationships of SD-WISE scores to Gf-PS and Gf-EF were tested in bivariate correlational analyses and multiple regression models adjusted for demographics (age, sex, and education). Exploratory analyses evaluated the relationships between SD-WISE and age, episodic memory performance, and dorsolateral and ventromedial prefrontal cortical volumes on magnetic resonance imaging.

Wisdom showed a small, positive association with Gf-EF (r = 0.181 [95% CI 0.016, 0.336], p = .031), which was reduced to nonsignificance upon controlling for demographics, and no association with Gf-PS (r = 0.019 [95% CI −0.179, 0.216], p = .854). Wisdom demonstrated a small, negative correlation with age (r = −0.197 [95% CI −0.351, −0.033], p = .019), but was not significantly related to episodic memory or prefrontal volumes.

Our findings indicate that most of the variance in wisdom (>95%) is unaccounted for by Gf. The independence of wisdom from cognitive functions that reliably show age-associated declines suggests that it may hold unique potential to bolster decision-making, interpersonal functioning, and other everyday activities in older adults.

This systematic review aims to identify published randomized controlled trials (RCTs) that evaluated the use of anticonvulsants for the prevention and/or treatment of delirium among older adults.

A comprehensive search of databases: MEDLINE ALL (Ovid), Embase (Ovid), PsycINFO (Ovid), Web of Science Core Collection and Cochrane Central Register of Controlled was conducted.

The search identified four RCTs that evaluated the use of anticonvulsants among older adults with delirium. One RCT evaluated the perioperative use of gabapentin among individuals undergoing spinal surgery and the development of postoperative delirium. One RCT evaluated the relationship between the use of perioperative gabapentin and the development of postoperative delirium among individuals undergoing spinal surgery and hip and knee arthroplasty. Two post-hoc analyses of RCTs evaluated the use of gabapentin and pregabalin among individuals undergoing total knee arthroplasty (TKA) and total hip arthroplasty (THA). The perioperative use of gabapentin reduced the incidence of postoperative delirium among older adults undergoing spinal surgery. The perioperative use of gabapentin did not reduce the rates, severity or duration of postoperative delirium among older adults who were undergoing spine and hip and knee arthroplasty. The perioperative use of gabapentin did not reduce the incidence or duration of postoperative delirium among older adults undergoing elective TKA. The perioperative use of pregabalin did not reduce the incidence of postoperative delirium among older adults undergoing elective THA. Gabapentin and pregabalin were well tolerated among the individuals enrolled in these trials. There were no RCTs identified that evaluated the use of other anticonvulsants for the prevention and/or treatment of delirium among older adults.

Based on current evidence, the routine use of anticonvulsants for the prevention and/or treatment of delirium among older adults cannot be recommended.

Purposeful adults may experience greater cognitive resilience because sense of purpose may help buffer against the effects of depressive symptoms and loneliness. We also evaluated whether these associations differed by race.

This study uses a wave of self-report data from the SPAN study of psychosocial aging.

Participants come from a representative sample of older adults in St. Louis.

Participants (N = 595) ages range from 65 to 78 (Mage = 71.46), with 18.3% of participants identifying as Black/African-American.

Sense of purpose was assessed with the Life Engagement Test, depressive symptoms with the Beck Depression Inventory-II, loneliness with the UCLA Loneliness Scale, and subjective cognitive decline with the AD-8.

Correlational analyses supported predictions that sense of purpose was negatively related to subjective cognitive decline, whereas depressive symptoms and loneliness were positively related (|r|s > .30, ps < .001). For loneliness, but not depression, this association was moderated by sense of purpose (b = −0.43, p < .001). A relatively high sense of purpose attenuated associations between loneliness and subjective cognitive decline. A three-way race × purpose × loneliness interaction (b = −0.25, p = .021) revealed that the buffering effects of sense of purpose on subjective cognitive decline were stronger for Black adults.

This study provided partial support for the buffering hypothesis, showing that sense of purpose may help mitigate the cognitive decrements associated with loneliness. Future research needs to consider how purpose-promoting programs may support healthy cognitive aging, particularly among Black older adults and those who experience greater social isolation.

Wisdom researchers acknowledge the complex nature of this ancient construct, although they are yet to agree on its core components. A key question in the literature is whether Openness and Humour are aspects of wisdom or whether Openness is an antecedent of wisdom with Humour as a consequence.

Using structural equation modelling, we evaluated data from 457 online respondents aged 16–87 years (M age = 35.19, SD = 17.45). We analyzed a model with Openness as a precursor to Wisdom (conceptualised as a latent mediator variable using parcels of the SAWS Experience, Reminiscence/Reflection, and Emotional Regulation items), with Humor as outcome. We compared this model with a model using Wisdom as a latent mediator variable using parcels of the Three-Dimensional Wisdom Scale-12 (3D-WS-12).

A model using Self-Assessed Wisdom Scale (SAWS)-9 latent mediator variable with Openness as precursor to wisdom and Humour as a consequence was good fit for the data and displayed full mediation. Similarly, a model using the 3D-WS-12 as latent mediator variable to measure wisdom and with Openness as a precursor to wisdom and Humour as a consequence also fits the data with full mediation.

These findings provide empirical support for theoretical suggestions in the literature that Openness is a precursor to wisdom and that Humour is a consequence of wisdom using two of the most common self-report measures of wisdom. An improved understanding of the nature of wisdom and especially of its potential precursors can also be of use in future efforts to facilitate the development of wisdom.

Depression is prevalent among older persons, which seriously threatens their life satisfaction. This study aimed to explore the internal mechanisms by which depression influences life satisfaction among the elderly, as well as the mediating and moderating effects of ostracism and economic income, respectively, in a sample of rural older adults across China.

This was a cross-sectional survey conducted as part of the project “Thousands of People and Hundreds of Villages (2019).”

Participants were rural older adults from 31 provincial-level administrative units across China.

The sample composed of 1,754 participants aged 60 years and over.

Depression was assessed with the depression subscale of the Depression Anxiety Stress Scales, life satisfaction with the Satisfaction with Life Scale, ostracism with the Ostracism Experience Scale (OES), and economic income and other control variables with related demographic scales. Moderation and mediation analyses were performed using the regression-based approach as conducted by Hayes (2013).

Depression negatively predicted life satisfaction among the elderly. Ostracism played a partially mediating role between depression and life satisfaction. Economic income moderated the effect of depression and ostracism on life satisfaction: High economic income weakened the negative effect of depression on life satisfaction and enhanced the negative effect of ostracism on life satisfaction.

Improving depressed elderly people’s interpersonal relationships and financial support could improve their life satisfaction.

To examine the direct and indirect effects of age, APOE ϵ4 genotype, amyloid positivity, and volumetric reductions in AD-prone brain regions as it relates to semantic intrusion errors reflecting proactive semantic interference (PSI) and the failure to recover from proactive semantic interference (frPSI) on the Loewenstein-Acevedo Scales of Semantic Interference and Learning (LASSI-L), a cognitive stress test that has been consistently more predictive of preclinical and prodromal Alzheimer’s disease (AD) than traditional list-learning tests.

Cross-sectional study.

1Florida Alzheimer’s Disease Research Center baseline study.

Two-hundred and twelve participants with Mini-Mental State Examination (MMSE) score above 16 and a broad array of cognitive diagnoses ranging from cognitively normal (CN) to dementia, of whom 58% were female, mean age of 72.1 (SD 7.9).

Participants underwent extensive clinical and neuropsychological evaluations, MR and amyloid Positron Emission Tomography/Computer/Computer Tomography (PET/CT) imaging, and analyses of APOE ϵ4 genotype. Confirmatory path analyses were conducted in the structural equation modeling framework that estimated multiple equations simultaneously while controlling for important covariates such as sex, education, language of evaluation, and global cognitive impairment.

Both amyloid positivity and decreased brain volumes in AD-prone regions were directly related to LASSI-L Cued B1 and Cued B2 intrusions (sensitive to PSI and frPSI effects) even after controlling for covariates. APOE ϵ4 status did not evidence direct effects on these LASSI-L cognitive markers, but rather exerted their effects on amyloid positivity, which in turn related to PSI and frPSI. Similarly, age did not have a direct relationship with LASSI-L scores, but exerted its effects indirectly through amyloid positivity and volumes of AD-prone brain regions.

Our study provides insight into the relationships among age, APOE ϵ4, amyloid, and brain volumetric reductions as it relates to semantic intrusion errors. The investigation expands our understanding of the underpinnings of PSI and frPSI intrusions in a large cohort.

Informal carers play an essential role in the care of individuals with Parkinson’s disease (PD). This role, however, is often fraught with difficulties, including emotional, physical, and financial. Coping styles and relationship quality have been hypothesized to influence the impact of stressors. The aim of this study is to examine the relationship between carers’ coping style, relationship quality, and carer burden.

Cross-sectional.

Thirty-nine PD patient carer dyads were included in the study.

Participants completed self-rated questionnaires including the Dyadic Adjustment Scale, Zarit Burden Interview, and Brief Coping Orientation to Problems Experienced Inventory.

Correlational analyses found significant and positive correlation between carer burden and all three coping styles (problem-focused, emotion-focused, and dysfunctional). There was also a moderate association between carers’ perceived relationship quality and satisfaction and carer burden. Regression analyses found that carer’s gender, severity of PD, relationship quality, emotion-focused, and dysfunctional coping styles did not predict carer burden. Conversely, problem-focused coping style predicted carer burden.

The results highlight that there is no perfect way to react and care for a loved one and serves as important information for practitioners who design and implement interventions.

Depression is common in persons experiencing mild cognitive impairment (MCI), with 32% (95% Cl 27, 37) overall experiencing depression. Persons with MCI who have depression have more cognitive changes compared to those without depression. To understand how we can detect depressive symptoms in persons with MCI, we undertook a systematic review to identify tools that were validated compared with a reference standard.

We searched MEDLINE, EMBASE, PsycINFO, and Cochrane from inception to April 25, 2021, and conducted a gray literature search. Title/abstract and full-text screening were completed in duplicate. Demographic information, reference standards, prevalence, and diagnostic accuracy measures were then extracted from included articles (PROSPERO CRD: CRD42016052120).

Across databases, 8,748 abstracts were generated after removing duplicates. Six hundred and sixty-five records underwent full-text screening, with six articles included for data extraction. Nine tools were identified compared to a reference standard, with multiple demonstrating a sensitivity of 100% (Brief Assessment Schedule Depression Cards, Beck Depression Inventory-II, Cornell Scale for Depression in Dementia, Zung Self-Rated Depression Scale, and the Neuropsychiatric Inventory). The second highest sensitivity reported was 89% (Patient Health Questionnaire-9). Too few studies were available for a meta-analysis.

Multiple depression detection tools have been examined amongst MCI outpatients, with several showing high sensitivity. However, this evidence is only present in single studies, with little demonstration of how differing MCI types affect accuracy. More research is needed to confirm the accuracy of these tools amongst persons with MCI. At this time, several tools could be suitable for use in cognitive clinics.
