Abstract
The current study examined potential gender differences in the associations between informal caregiving, poor mental health, and subjective cognitive decline (SCD). Data were obtained from the U.S. Behavioral Risk Factor Surveillance System (N = 16,042; 9,410 women, 6,632 men). Multivariate linear and logistic regression models were used to obtain adjusted βs and odds ratios (ORs), and 95% confidence intervals (CIs) depicting the association between informal caregiving, poor mental health, and SCD overall and by gender. Caregiving was positively associated with poor mental health among men (adjusted β = 2.60; 95% CI [2.59, 2.62]) and women (adjusted β = 0.40; 95% CI [0.23, 0.57]). Poor mental health was positively associated with SCD among men (adjusted OR = 1.05; 95% CI [1.02, 1.08]) and women (adjusted OR = 1.07; 95% CI [1.04, 1.10]). Poor mental health may be associated with SCD, irrespective of gender, and additional studies are needed that will identify key variables influencing SCD among male and female informal caregivers.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17072190. [PMID: 32218278 PMCID: PMC7177542 DOI: 10.3390/ijerph17072190] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Revised: 03/17/2020] [Accepted: 03/21/2020] [Indexed: 01/19/2023]
Abstract
The role of informal caregiver of cancer patients is considered a situation of chronic stress that could have impact on cognitive functioning. Our aim was to evaluate differences in perceived stress, subjective memory complaints, self-esteem, and resilience between caregivers and non-caregivers, as well as the possible mediational role of burden in caregivers. The sample was composed of 60 participants divided into two groups: (1) Primary informal caregivers of a relative with cancer (CCG) (n = 34); and (2) non-caregiver control subjects (Non-CG) (n = 26). All participants were evaluated through a battery of tests: Socio-demographic questionnaire, subjective memory complaints questionnaire (MFE-30), Rosenberg Self-Esteem Scale, resilience (CD-RISC-10), and perceived stress scale (PSS). The CCG group also completed the Zarit burden interview. Results indicated that CCG displayed higher scores than Non-CG in MFE-30 (p = 0.000) and PSS (p = 0.005). In the CCG group, Pearson correlations indicated that PSS showed a negative relationship with resilience (p = 0.000) and self-esteem (p = 0.002) and positive correlation with caregiver’s burden (p = 0.015). In conclusion, CCG displayed higher number of subjective memory complaints and higher perceived stress than Non-CG, whereas no significant differences were obtained on self-esteem and resilience. These results could aid in designing new intervention strategies aimed to diminish stress, burden, or cognitive effects in informal caregivers of cancer patients.

Abstract
Introduction: Caring for a family member with a long-term illness is a significant source of chronic stress that might significantly accelerate the cognitive ageing of informal caregivers. Nevertheless, the absence of a defined theoretical body of literature on the neuropsychology of this population makes it difficult to understand what the characteristic neuropsychological deficits of these caregivers are.Aims: The main aim of this study is to carry out a systematic review of studies of cognitive deficits present in informal caregivers of people with several chronic pathologies, and analyse the effects of cognitive-behavioural interventions on caregivers' cognition.Methods: The scientific literature was reviewed following the PRISMA quality criteria for reviews using the following digital databases: PubMEd, PsycINFO, and Dialnet.Results: Identification of 2046 abstracts and retrieval of 211 full texts led to the inclusion of 38 papers. The studies showed heterogeneous results, but most of the cross-sectional studies reviewed that employed neuropsychological assessments concluded that informal caregivers reported a generalized cognitive deterioration, especially memory dysfunctions (i.e. learning verbal, visuospatial, and digit information). Moreover, they also presented low selective attention and capacity for inhibition, along with slow processing speed. Longitudinal studies confirmed that caregivers whose care situation was more prolonged showed a marked deterioration in their overall cognitive state, memory, processing speed, and vocabulary richness. However, although the patient's death does not seem to reverse the neuropsychological alterations in caregivers, cognitive-behavioural interventions that employ techniques to reduce stress levels, cognitive biases, and inadequate adaptation schemas seem to improve some of the aforementioned cognitive abilities.Conclusions: Results from this synthesis and critical analysis of neuropsychological deficits in informal caregivers offer guidelines for diagnosing caregivers' cognitive status by including a test battery covering all the domains considered relevant. Finally, given the ability of cognitive behavioural interventions to improve cognition in caregivers, further studies on their long-term effects on caregivers are warranted.Chronic stress entails an acceleration of the cognitive ageingCross-sectional studies concluded that informal caregivers reported a generalized cognitive deteriorationCognitive-behavioural interventions seem to improve cognitive abilities of caregivers.

Abstract
Dementia is a common and debilitating syndrome with enormous impact on individuals and societies. Preventing disease onset or progression would translate to public health and societal benefits. In this review, we discuss the latest evidence on interventions that may show promise for the prevention of cognitive decline. We appraise existing evidence primarily drawn from randomized controlled trials, systematic reviews, and meta-analyses, but also highlight observational studies in humans and relevant work in model organisms. Overall, there is currently limited evidence to support a cause-effect relationship between any preventive strategy and the development or progression of dementia. However, studies to date suggest that a multifactorial intervention comprising regular exercise and healthy diet, along with the amelioration of vascular risk factors, psychosocial stress, and major depressive episodes may be most promising for the prevention of cognitive decline. We discuss the challenges, future directions, and implications of this line of research.

A systematic review of the psychobiological burden of informal caregiving for patients with dementia: Focus on cognitive and biological markers of chronic stress.

Abstract
As the physiological impact of chronic stress is difficult to study in humans, naturalistic stressors are invaluable sources of information in this area. This review systematically evaluates the research literature examining biomarkers of chronic stress, including neurocognition, in informal dementia caregivers. We identified 151 papers for inclusion in the final review, including papers examining differences between caregivers and controls as well as interventions aimed at counteracting the biological burden of chronic caregiving stress. Results indicate that cortisol was increased in caregivers in a majority of studies examining this biomarker. There was mixed evidence for differences in epinephrine, norepinephrine and other cardiovascular markers. There was a high level of heterogeneity in immune system measures. Caregivers performed more poorly on attention and executive functioning tests. There was mixed evidence for memory performance. Interventions to reduce stress improved cognition but had mixed effects on cortisol. Risk of bias was generally low to moderate. Given the rising need for family caregivers worldwide, the implications of these findings can no longer be neglected.

Abstract
PURPOSE OF REVIEW The number of informal caregivers providing assistance to adults is increasing commensurate with our aging society. Sleep disturbances are prevalent in caregivers and associated with negative physical, medical, and functional outcomes. Here, we describe the predisposing, precipitating, and perpetuating factors contributing to the development of sleep problems in caregivers, and discuss three understudied caregiving populations that have clinical importance and unique circumstances influencing sleep quality and health. RECENT FINDINGS There is clear evidence supporting the interaction between sleep loss, caregiving stress, and vulnerability to chronic disease. Telehealth and telemedicine sleep interventions for caregivers combined with assistive technologies targeting care-receivers have potential to be more individualized, affordable, and widely accessible than traditional in-person insomnia treatment approaches. Limited data exist describing the etiology and treatment of sleep problems in caregivers of veterans, medical patients newly discharged from the hospital, and developmentally disabled adults. SUMMARY There is a growing literature describing the general determinants of sleep disturbances in caregivers, the health consequences of these disturbances, and intervention strategies for treating them. Identifying effective sleep treatments suited to more specialized caregiving situations and increasing intervention access will help caregivers continue to provide quality care while protecting their own health and well-being.

Abstract
Objetivo: La incidencia y prevalencia de enfermedades de larga duración como el cáncer se ha incrementado en los últimos años. En este contexto, nuestro principal objetivo será el análisis de las principales consecuencias que la exposición a una situación de estrés crónico, como es el cuidado de un paciente oncológico, tiene sobre la salud psicosocial y la función cognitiva del cuidador informal y su relación con variables moduladoras. Método: Se realizó una revisión bibliográfica en las bases de datos PubMed y PsychINFO sobre las consecuencias de la situación de cuidado en pacientes crónicos. Resultados: Diversos estudios sugieren que la condición de cuidador de un paciente oncológico puede considerarse una situación estresante que conlleva consecuencias tanto a nivel de salud física como psicosocial del cuidador además de un deterioro en su funcionamiento cognitivo que pueden estar modulados por diferentes variables. Conclusión: Estos datos sugieren la importancia de implementar programas de intervención que amortigüen las consecuencias deletéreas de la labor de cuidado.
