Guardianship Before and Following Hospitalization.

When ethics committees are consulted about patients who have or need court-appointed guardians, they lack empirical evidence about several common issues, including the relationship between guardianship and prolonged, potentially medically unnecessary hospitalizations for patients. To provide information about this issue, we conducted quantitative and qualitative analyses using a retrospective cohort from Veterans Healthcare Administration. To examine the relationship between guardianship appointment and hospital length of stay, we first compared 116 persons hospitalized prior to guardianship appointment to a comparison group (n = 348) 3:1 matched for age, diagnosis, date of admission, and comorbidity. We then compared 91 persons hospitalized in the year following guardianship appointment to a second matched comparison group (n = 273). Mean length of stay was 30.75 days (SD = 46.70) amongst those admitted prior to guardianship, which was higher than the comparison group (M = 7.74, SD = 9.71, F = 20.75, p < .001). Length of stay was lower following guardianship appointment (11.65, SD = 12.02, t = 15.16, p < .001); while higher than the comparison group (M = 7.60, SD = 8.46), differences were not associated with guardianship status. In a separate analysis involving 35 individuals who were hospitalized both prior to and following guardianship, length of stay was longer in the year prior (M = 23.00, SD = 37.55) versus after guardianship (M = 10.37, SD = 10.89, F = 4.35, p = .045). In qualitative analyses, four themes associated with lengths of stay exceeding 45 days prior to guardianship appointment were: administrative issues, family conflict, neuropsychiatric comorbidity, and medical complications. Our results suggest that persons who are admitted to hospitals, and subsequently require a guardian, experience extended lengths of stay for multiple complex reasons. Once a guardian has been appointed, however, differences in hospital lengths of stay between patients with and without guardians are reduced.

Cost Utility of cognition-enhancing interventions for individuals with first-episode psychosis: a naturalistic evaluation.

BACKGROUND: Although effective treatments are available to address the cognitive deficits experienced by individuals with first-episode psychosis, provision of such treatments within Coordinated Specialty Care (CSC) programs is rare. One factor that may contribute to this is uncertainty about the cost implications of providing cognitive-enhancing treatments within the American mental healthcare system. The aim of this study is to complete a naturalistic evaluation of the cost utility of incorporating two different cognitive-enhancing interventions within an American CSC program. METHODS: Participants included 66, predominately white (75.38%), individuals with first-episode psychosis (19 women and 47 men) with a mean age of 22.71 years. Quality adjusted life years (QALYs) and cost of care were tracked among these individuals during their participation in a CSC program. These data were compared among three groups of participants during their first six months of care: (i) individuals who participated in metacognitive remediation therapy (MCR), (ii) individuals who participated in computerized cognitive remediation (CCR), and (iii) individuals who participated in no cognitive-enhancing intervention. RESULTS: Participation in MCR, but not CCR, was associated with larger gains in QALYs than participation in no cognitive-enhancing intervention within a CSC program. Moreover, data support the cost utility of MCR as compared to CCR or no-cognitive enhancing intervention within a CSC program. Conversely, CCR did not appear to be a cost-effective addition to CSC services. CONCLUSIONS: Our results highlight the potential cost utility of incorporating MCR within CSC programs for individuals with first-episode psychosis. However, given study limitations, these results should be interpreted cautiously until replicated by large, randomized controlled trials.

Social participation predicts cognitive functioning in aging adults over time: comparisons with physical health, depression, and physical activity.

OBJECTIVES: Several risk and protective factors are associated with changes in cognitive functioning in aging adults - including physical health, depression, physical activity, and social activities - though the findings for participation in social activities are mixed. This study investigated the longitudinal association between social participation and two domains of cognitive functioning, memory and executive function. A primary goal of our analyses was to determine whether social participation predicted cognitive functioning over-and-above physical health, depression, and physical activity in a sample with adequate power to detect unique effects. METHOD: The sample included aging adults (N = 19,832) who participated in a large, multi-national study and provided data across six years; split into two random subsamples. Unique associations between the predictors of interest and cognitive functioning over time and within occasion were assessed in a latent curve growth model. RESULTS: Social participation predicted both domains of cognitive functioning at each occasion, and the relative magnitude of this effect was comparable to physical health, depression, and physical activity level. In addition, social participation at the first time point predicted change in cognitive functioning over time. The substantive results in the initial sample were replicated in the second independent subsample. CONCLUSION: Overall, the magnitude of the association of social participation is comparable to other well-established predictors of cognitive functioning, providing evidence that social participation plays an important role in cognitive functioning and successful aging.

Body Mass and Physical Activity Uniquely Predict Change in Cognition for Aging Adults.

BACKGROUND: Physical activity and body mass predict cognition in the elderly. However, mixed evidence suggests that obesity is associated with poorer cognition, while also protecting against cognitive decline in older age. PURPOSE: We investigated whether body mass independently predicted cognition in older age and whether these associations changed over time. METHODS: A latent curve structural equation modeling approach was used to analyze data from a sample of aging adults (N = 8442) split into two independent subsamples, collected over 6 years. RESULTS: Lower baseline Body Mass Index (BMI) and higher physical activity independently predicted greater baseline cognition (p < 0.001). Decreases in BMI and physical activity independently predicted greater decline in the slope of cognition (p < 0.001). CONCLUSIONS: Our results support the obesity paradox in cognitive aging, with lower baseline body mass predicting better cognition, but less decline over time protecting against cognitive decline. We discuss how weight loss in the elderly may serve as a useful indicator of co-occurring cognitive decline, and we discuss implications for health care professionals.

The Early Psychosis Intervention Center (EPICENTER): development and six-month outcomes of an American first-episode psychosis clinical service.

BACKGROUND: There is growing evidence that specialized clinical services targeted toward individuals early in the course of a psychotic illness may be effective in reducing both the clinical and economic burden associated with these illnesses. Unfortunately, the United States has lagged behind other countries in the delivery of specialized, multi-component care to individuals early in the course of a psychotic illness. A key factor contributing to this lag is the limited available data demonstrating the clinical benefits and cost-effectiveness of early intervention for psychosis among individuals served by the American mental health system. Thus, the goal of this study is to present clinical and cost outcome data with regard to a first-episode psychosis treatment center within the American mental health system: the Early Psychosis Intervention Center (EPICENTER). METHODS: Sixty-eight consecutively enrolled individuals with first-episode psychosis completed assessments of symptomatology, social functioning, educational/vocational functioning, cognitive functioning, substance use, and service utilization upon enrollment in EPICENTER and after 6 months of EPICENTER care. All participants were provided with access to a multi-component treatment package comprised of cognitive behavioral therapy, family psychoeducation, and metacognitive remediation. RESULTS: Over the first 6 months of EPICENTER care, participants experienced improvements in symptomatology, social functioning, educational/vocational functioning, cognitive functioning, and substance abuse. The average cost of care during the first 6 months of EPICENTER participation was lower than the average cost during the 6-months prior to joining EPICENTER. These savings occurred despite the additional costs associated with the receipt of EPICENTER care and were driven primarily by reductions in the utilization of inpatient psychiatric services and contacts with the legal system. CONCLUSIONS: The results of our study suggest that multi-component interventions for first-episode psychosis provided in the US mental health system may be both clinically-beneficial and cost-effective. Although additional research is needed, these findings provide preliminary support for the growing delivery of specialized multi-component interventions for first-episode psychosis within the United States.

Help Me Understand: Providing Palliative Care to Individuals With Serious Mental Illness.

Individuals with serious mental illness (SMI) have shortened life expectancy with increased risk of developing comorbid medical illnesses. They might have difficulty accessing care and can be lost to follow-up due to complex socioeconomic factors, placing them at greater risk of dying from chronic or undiagnosed conditions. This, in combination with stigma associated with SMI, can result in lower quality end-of-life care. Interdisciplinary palliative care teams are in a unique position to lend assistance to those with SMI given their expertise in serious illness communication, values-based care, and psychosocial support. However, palliative care teams might be unfamiliar with the hallmark features of the various SMI diagnoses. Consequently, recognizing and managing exacerbations of SMI while delivering concurrent palliative or end-of-life care can feel challenging. The goal of this narrative review is to describe the benefits of providing palliative care to individuals with SMI with concrete suggestions for communication and use of recovery-oriented language in the treatment of individuals with SMI. The salient features of 3 SMI diagnoses-Bipolar Disorders, Major Depressive Disorder, and Schizophrenia-are outlined through case examples. Recommendations for working with individuals who have SMI and other life-limiting illness are provided, including strategies to effectively manage SMI exacerbations.

Episodic Memory and Executive Function Are Differentially Affected by Retests but Similarly Affected by Age in a Longitudinal Study of Normally-Aging Older Adults.

Episodic memory and executive function are two cognitive domains that have been studied extensively in older adults and have been shown to decline in normally-aging older individuals. However, one of the problems with characterizing cognitive changes in longitudinal studies has been separating effects attributable to normal aging from effects created by repeated testing or practice. In the present study, 166 people aged 65 and older were enrolled over several years and tested at least 3 times at variable intervals (M = 3.2 yrs). The cognitive measures were composite scores. Each composite was made up of five neuropsychological tests, previously identified through factor analysis. For one pair of composite scores, variance attributable to age was removed from each subtest through regression analyses before z-scores were computed, creating two age-corrected composites. A second pair of composites were not age-corrected. Using linear mixed-effects models, we first explored retest effects for each cognitive domain, independent of age, using the age-corrected composites. We then modeled aging effects using the age-uncorrected composites after subtracting out retest effects. Results indicated significant retest effects for memory but not for executive function, such that memory performance improved across the three testing sessions. When these practice effects were removed from the age-uncorrected data, effects of aging were evident for both executive and memory function with significant declines over time. We also explored several individual difference variables including sex, IQ, and age at the initial testing session and across time. Although sex and IQ affected performance on both cognitive factors at the initial test, neither was related to practice effects, although young-older adults tended to benefit from practice to a greater extent than old-older adults. In addition, people with higher IQs showed slower age-related declines in memory, but no advantages in executive function. These findings suggest that (a) aging affects both memory and executive function similarly, (b) higher IQ, possibly reflecting cognitive reserve, may slow age-related declines in memory, and (c) practice through repeated testing enhances performance in memory particularly in younger-older adults, and may therefore mask aging effects if not taken into account.

Differences between young and older adults in unity and diversity of executive functions.

Miyake and colleagues (2000) identified three independent but correlated components of executive function in young adults - set shifting, inhibition, and updating. The present study compared the factor structure in young adults to two groups of older adults (ages 60-73 and 74-98). A three-factor model of shifting, inhibition and updating was confirmed in young adults, but the factors were weakly or uncorrelated. In both older groups, a two-factor solution was indicated, updating/inhibition and shifting, which were moderately correlated in young-older adults, and strongly correlated in the old-older group. A nested factors model in the oldest group revealed a common factor, which loaded on all but one of the tests, and a shifting-specific factor. We concluded that in young adulthood, shifting, updating and inhibition may operate relatively independently. As people age and processing becomes less efficient, they may rely increasingly on general executive control processes, reallocating their limited resources to optimize performance.

End-of-Life Care for Persons Under Guardianship.

CONTEXT: Guardians are surrogate decision makers appointed by a court when other health care decision-makers are unable, unwilling, or unavailable to make decisions. Prior studies suggest that persons under guardianship may experience delays in transitions of care. OBJECTIVES: To compare quality of end-of-life care for persons under guardianship to a matched group on objective indicators and to identify narrative themes characterizing potential obstacles to quality end-of-life care. METHODS: One hundred sixty-seven persons under guardianship who died between 2003 and 2019 within the Veterans Healthcare Administration in Massachusetts and Connecticut matched on a 1:1 basis to persons without guardians. The groups were compared on treatment specialty at death, days of hospice and intensive care unit care, and receipt of palliative care consultation. Additionally, patient narratives for those under guardianship with extended lengths in intensive care unit were subjected to qualitative analysis. RESULTS: Overall, <1% were under guardianship. Within this sample of persons who died within the Veterans Health Administration, persons under guardianship were as likely as patients in the comparison group to receive palliative care consultation (odds ratio [CI] = 0.93 [.590-1.46], P = .359), but were more likely to have ethics consultation (odds ratio [CI] = 0.25 [0.66-0.92], P = .036) and have longer lengths of ICU admission (ß = -.34, t = -2.70, P = .009). Qualitative findings suggest that issues related to family conflict, fluctuating medical course, and limitations in guardian authority may underlie extended lengths of stay. CONCLUSION: Guardianship appears to be rare, and as a rule, those under guardianship have equal access to hospice and palliative care within Veterans Health Administration. Guardianship may be associated with health-care challenges in a small number of cases, and this may drive perceptions of adverse outcomes.

Working memory predicts subsequent episodic memory decline during healthy cognitive aging: evidence from a cross-lagged panel design.

Aging adults experience declines in working memory and episodic memory, however, it is unclear how these declines operate over time. Decreased working memory may be associated with early changes in episodic memory, by reducing older adults' ability to meaningfully integrate new information into pre-existing schemas and recall information without the assistance of cues. Given the increased prevalence of Alzheimer's disease, and concerns based on subjective memory changes, it is important to understand how these processes interact over time. To assess the relationship between working memory and episodic memory during healthy cognitive aging, we performed neuropsychological assessments at multiple time points in a sample of 310 community-dwelling older adults. Using a cross-lagged panel design, we demonstrated that the lagged associations between working memory and later episodic free recall were 50% larger than the lagged associations between episodic recall and later working memory, suggesting working memory may be a useful metric of future episodic memory decline.

Self-reference and emotional memory effects in older adults at increased genetic risk of Alzheimer's disease.

The present study investigated whether cognitively healthy older adults who are carriers of the ε4 allele of apolipoprotein E, the most prevalent genetic risk factor for late-onset Alzheimer's disease, benefit from self-referential processing and emotional processing to the same degree as noncarriers of this gene. Participants encoded emotional and nonemotional narratives using a baseline-orienting task, semantic elaboration, or imagination-based self-referential processing and then completed a recognition memory test. Both groups of older adults showed enhanced recognition memory for narrative information following self-referential processing relative to semantic elaboration, and the magnitude of this memory effect was not affected by ε4 status. However, older adult ε4 carriers did not show an emotional enhancement effect, whereas older adult ε4 noncarriers did. These results indicate that whereas the self-reference effect is not attenuated in cognitively healthy older adults ε4 carriers, deficits in emotional memory may be an early cognitive marker of abnormal decline.

Social cognition and the course of social functioning in first-episode psychosis.

BACKGROUND: Social functioning deficits greatly affect individuals with psychotic disorders resulting in decreased ability to maintain relationships, jobs and pursuit of educational goals. Deficits in social cognition have been hypothesized to be an important contributor to these deficits in social functioning. In particular, 5 domains of social cognition have been suggested to be relevant in the study of psychotic disorders: (1) attributional style, (2) emotion recognition, (3) social knowledge, (4) social perception and (5) theory of mind. Yet, to date, no study has simultaneously investigated the association between these 5 domains of social cognition and social functioning. METHODS: We investigated the cross-section and longitudinal association between social cognition and social functioning among 71 individuals with first-episode psychosis. RESULTS: We found modest cross-sectional associations between social cognition and social functioning that were often in the unexpected direction (ie, greater social cognition associated with worse social functioning). Social cognition at baseline was not associated with the longitudinal course of social functioning. CONCLUSIONS: These unexpected findings fail to align with previous research that has documented a more robust relationship between these 2 constructs, and raise critical questions with regard to the nature of the association between social cognition and social functioning among individuals with first-episode psychosis.

An uncontrolled trial of multi-component care for first-episode psychosis: Effects on social cognition.

Growing evidence suggests that specialized, multi-component treatment programmes produce improvements in numerous outcomes among individuals with first-episode psychosis. However, these programmes often lack interventions specifically designed to address deficits in social cognition. This raises questions about the effectiveness of such programmes in addressing deficits in social cognition that accompany psychotic disorders. We investigated the effect of participation in a multi-component treatment programme on social cognition among 71 individuals with first-episode psychosis. Participants experienced gains in emotion processing, social knowledge, social perception and theory of mind. However, after controlling for multiple comparisons, these improvements were limited to theory of mind and recognition of social cues in low emotion interactions. Although our findings should be interpreted cautiously, they raise the possibility that individuals participating in multi-component treatment programmes for first-episode psychosis without interventions specifically targeting social cognition may still experience gains in social cognition.

Meta-cognitive skills training enhances computerized cognitive remediation outcomes among individuals with first-episode psychosis.

AIM: Meta-cognitive skills training (MST) is a frequent component of cognitive remediation programmes for individuals with psychosis. However, no study has investigated whether incorporating such activities produces increased clinical benefits compared with computerized cognitive remediation alone. METHODS: Individuals with first-episode psychosis who completed computerized cognitive remediation with concurrent meta-cognitive skills training (CCR + MST) were compared with a historical control group who received computerized cognitive remediation alone (CCR) and did not differ from the CCR + MST group with regard to pre-intervention cognition, diagnosis, age, duration of psychotic illness or sex. Participants completed assessments of cognition and real-world functioning before and after 6 months of treatment. RESULTS: Individual receiving CCR + MST experience greater gains in cognition and real-world functioning than individuals who received CCR. CONCLUSIONS: MST may be an important component within cognitive remediation programmes for first-episode psychosis.

A dyadic approach to health, cognition, and quality of life in aging adults.

Married couples evidence interdependence in their psychological and physical wellbeing across the life span. This is particularly true in aging populations that experience declines in physical health and cognitive ability. This study investigated the effects of partners' physical health and cognition on quality of life (QoL) in a series of bivariate latent curve growth models. The sample included aging married couples (N = 8,187) who participated in the Survey of Health, Ageing, and Retirement in Europe (SHARE) study and provided data across 6 years. Results indicated that husbands' and wives' baseline levels and rates of change in QoL covaried significantly over time. In addition, husbands' and wives' physical health and cognition predicted their partners' baseline level of QoL above and beyond their own health and cognition, and these effects were of equivalent size for both men and women. The findings suggest that as couples age, husbands' and wives' QoL, cognition, and health are predictive of their partners' QoL.

Clinical correlates of distorted auditory perception in first-episode psychosis.

AIM: Auditory hallucinations are hypothesized to be based in distorted sensory perceptions, with increasingly distorted perceptions of reality possibly prompting the first psychotic phase of schizophrenia spectrum disorders. Our goal was to examine the association between distorted auditory perceptions and psychotic symptomatology, social functioning and quality of life among individuals with first-episode psychosis. METHODS: Forty individuals with first-episode psychosis completed assessments of distorted auditory perception, psychotic symptomatology, social functioning and quality of life. RESULTS: Both negative (greater symptomatology) and positive clinical correlates (better quality of life) were associated with greater distorted auditory perceptions. CONCLUSIONS: Our findings suggest that distorted auditory perceptions are associated with both positive and negative clinical correlates among individuals with first-episode psychosis. These results highlight the potential clinical importance of balancing the goal of symptomatic reduction with the need to maintain healthy coping strategies that may be biologically and psychologically entwined with the symptoms of psychosis, themselves.

A randomized controlled trial of cognitive remediation and d-cycloserine for individuals with bipolar disorder.

BACKGROUND: Cognitive remediation (CR) has shown significant promise in addressing the cognitive deficits that accompany serious mental illness. However, this intervention does not appear to completely ameliorate the cognitive deficits that accompany these illnesses. D-cycloserine (DCS), an NMDA receptor partial agonist, has been shown to enhance the therapeutic benefits of learning-based psychosocial interventions for psychiatric disorders. Thus, the goal of this study is to examine the utility of combining cognitive remediation and d-cycloserine in the treatment of cognitive deficits among individuals with bipolar disorder. METHODS/DESIGN: Approximately forty individuals with bipolar disorder will be recruited to participate in this study. Participants will be randomized to one of two study arms: CR + DCS or CR + placebo. The primary outcome for this study is change in cognitive functioning. We will also examine several secondary outcomes, including the rate of change of cognitive functioning, social functioning, and symptomatology. DISCUSSION: Cognitive deficits are a rate-limiting factor in functional recovery among individuals with bipolar disorder. Unfortunately, treatment options for these deficits are limited. The results of the proposed study may reveal a valuable intervention strategy (i.e., CR with concurrent DCS) to improve cognitive functioning among individuals with bipolar disorder. Ultimately, this treatment strategy may prove useful in addressing the cognitive deficits that are ubiquitous across serious mental illnesses. TRIAL REGISTRATION: ClinicalTrials.gov NCT01934972.
