Problem-solving therapy reduces subjective burden levels in caregivers of family members with mild cognitive impairment or early-stage dementia: Secondary analysis of a randomized clinical trial.

ABSTRACT: OBJECTIVES:Interventions addressing burden have limited impact among long-term family caregivers. We examined whether problem-solving therapy (PST) would reduce burden levels of caregivers of individuals diagnosed with mild cognitive impairment (MCI) or early-stage dementia (AD). METHODS:Caregivers (N = 73) randomly received PST or nutritional training (NT). Burden measures were assessed over 1-year post-intervention. RESULTS:Relative to NT, caregivers receiving PST endorsed improved perceived burden levels over time, regardless of the type of caregiver. Distress over the care recipient's dementia-related behaviors remained low over time among MCI caregivers receiving PST, while these burden levels among MCI caregivers receiving NT rose over time. AD caregivers receiving PST endorsed reductions in these burden levels over time, while AD caregivers in the NT group endorsed higher burden levels over time. CONCLUSION:PST, taught early in the caregiving trajectory, improves subjective burden levels among caregivers of family members with relatively mild cognitive deficits.

Project description:BACKGROUND:Subjective cognitive decline (SCD) and anxiety symptoms both predict neurocognitive disorders, but the two correlate strongly with each other. It is unclear whether they reflect two independent disease processes in the development of neurocognitive disorders and hence deserve separate attention. This cohort study examined whether SCD and anxiety symptoms demonstrate independent risks of mild cognitive disorder and dementia (MCI/dementia). METHODS:The study included 14,066 participants aged ??50?years and diagnosed with normal cognition at baseline, recruited from Alzheimer's Disease Centers across the USA. The participants were evaluated for SCD and anxiety symptoms at baseline and followed up almost annually for incident MCI/dementia (median follow-up 4.5?years; interquartile range 2.2-7.7?years). SCD and anxiety symptoms were included in Cox regression to investigate their independent risks of MCI/dementia. RESULTS:SCD and anxiety symptoms demonstrated independent risks of MCI/dementia, with HR 1.9 (95% CI 1.7-2.1) and 1.3 (95% CI 1.2-1.5), respectively. Co-occurring SCD and anxiety symptoms demonstrated the highest risk (HR 2.4, 95% CI 1.9-2.9)-participants in this group had a 25% probability of developing MCI/dementia by 3.1?years (95% 2.4-3.7), compared to 8.2?years among those without SCD or anxiety (95% CI 7.9-8.6). The results remained robust even in the sensitivity analyses that took into account symptom severity and consistency of symptoms in the first 2 annual visits. CONCLUSIONS:The findings suggest that clinicians should not dismiss one over the other when patients present with both SCD and anxiety and that both constructs may potentially be useful to identify high-risk populations for preventive interventions and trials. The findings also point to the need for further research to clarify on the neurobiological distinctions between SCD and anxiety symptoms, which may potentially enrich our understanding on the pathogenesis of neurocognitive disorders.

Project description:BackgroundIn cognitively normal individuals, subjective cognitive decline (SCD) has been reported to predict MCI and dementia (MCI/dementia). However, prior studies mostly captured SCD at single time-points without considering the longitudinal course of SCD. This study examined whether the trajectories of SCD provide any added information-beyond one-time assessments of SCD-on the risk of MCI/dementia.MethodsThis cohort study included 5661 participants from the Alzheimer's Disease Centers across the USA, who were ≥ 50 years and had normal cognition in the first-four annual visits (year 1 to year 4). The participants were evaluated for SCD in the first-four annual visits (year 1 to year 4), and followed-up almost annually (year 4 up to year 14) for incident MCI/dementia. SCD trajectories (as identified from latent-class-growth-curve-analysis) were included in Cox regression to estimate their risks of MCI/dementia, with analyses further stratified by age (< 75 years versus ≥ 75 years; based on median-split).ResultsCompared to those without SCD (in the first-four annual visits), Intermittent SCD (i.e., reported in 1-2 of the first-four annual visits) predicted a higher risk (HR 1.4) and Persistent SCD (i.e., reported in 3-4 of the first-four annual visits) predicted the highest risk (HR 2.2), with the results remaining significant even after adjusting for baseline SCD. Age-stratified analysis revealed that the risk associated with Intermittent SCD was only present in older individuals, while risk related to Persistent SCD was consistently present across the younger and older age groups. Age compounded the effects of the trajectories, whereby older individuals with Persistent SCD had > 75% probability of developing MCI/dementia by 10 years, in contrast to < 25% probability by 10 years in younger individuals with No SCD.ConclusionsThe findings demonstrate the utility of SCD trajectories-especially when used in combination with age strata-in identifying high-risk populations for preventive interventions and trials. They also suggest a potential modification in the current SCD criteria, with the inclusion of "persistent SCD over several years" as a feature of SCD plus.

Project description:OBJECTIVES:Family caregivers of hospice patients have multiple needs as they try to cope during a stressful time. Translatable interventions effective in improving caregiver outcomes are greatly needed. Our objective was to assess the impact of a problem-solving intervention (called Problem-Solving Intervention to Support Caregivers in End-of-Life Care Settings [PISCES]) to support hospice caregivers on caregiver quality of life and anxiety, and compare its effectiveness delivered face to face and via videoconferencing. DESIGN:In this 4-year randomized clinical trial, caregivers were randomly assigned to a group receiving standard care with added "friendly calls" (attention control [AC] group), a group receiving standard care and PISCES delivered face to face (F2F), or a group receiving standard care and PISCES delivered via videoconferencing (VC). SETTING:Home hospice. PARTICIPANTS:A total of 514 caregivers participated (172 in AC, 171 in F2F, and 171 in VC). Caregivers were predominantly female (75%); mean age was 60.3 years. INTERVENTION:PISCES includes a structured curriculum delivered in three sessions and motivates caregivers to adopt a positive attitude, define problems by obtaining facts, set goals, and generate and evaluate solutions. MEASUREMENTS:Quality of life was measured by the Caregiver Quality of Life Index-Revised; anxiety was measured by the Generalized Anxiety Disorder 7-Item. Other measures included the Caregiver Reaction Assessment scale, demographic data, and an exit interview. RESULTS:Compared with AC, caregivers in the F2F condition had postintervention reduced anxiety (-1.31 [95% confidence interval [CI]?=?-2.11 to .50]; p?=?.004) and improved social (.57 [95% CI?=?.19-.95]; p?=?.01), financial (.57 [95% CI?=?.21-.93]; p?=?.004), and physical quality of life (.53 [95% CI?=?.19-.87]; p?=?.01). There were no differences in caregivers in the VC condition compared with the AC condition. CONCLUSION:The PISCES intervention improves caregiver outcomes and is effective when delivered in person. How to integrate technology to reduce the intervention delivery cost warrants further investigation.

Project description:Background: The recent COVID-19 pandemic is not only a major healthcare problem in itself, but also poses enormous social challenges. Though nursing homes increasingly receive attention, the majority of people with cognitive decline and dementia live at home. We aimed to explore the psychosocial effects of corona measures in memory clinic (pre-)dementia patients and their caregivers. Methods: Between April 28th and July 13th 2020, n = 389 patients of Alzheimer center Amsterdam [n = 121 symptomatic (age = 69 ± 6, 33%F, MMSE = 23 ± 5), n = 268 cognitively normal (age = 66 ± 8, 40% F, MMSE = 29 ± 1)] completed a survey on psychosocial effects of the corona measures. Questions related to social isolation, worries for faster cognitive decline, behavioral problems and discontinuation of care. In addition, n = 147 caregivers of symptomatic patients completed a similar survey with additional questions on caregiver burden. Results: Social isolation was experienced by n = 42 (35%) symptomatic and n = 67 (25%) cognitively normal patients and two third of patients [n = 129 (66%); n = 58 (75%) symptomatic, n = 71 (61%) cognitively normal] reported that care was discontinued. Worries for faster cognitive decline were existed in symptomatic patients [n = 44 (44%)] and caregivers [n = 73 (53%)], but were also reported by a subgroup of cognitively normal patients [n = 27 (14%)]. Both patients [n = 56 (46%) symptomatic, n = 102 (38%) cognitively normal] and caregivers [n = 72 (48%)] reported an increase in psychological symptoms. More than three quarter of caregivers [n = 111(76%)] reported an increase in patients' behavioral problems. A higher caregiver burden was experienced by n = 69 (56%) of caregivers and n = 43 (29%) of them reported that a need for more support. Discontinuation of care (OR = 3.3 [1.3-7.9]), psychological (OR = 4.0 [1.6-9.9]) and behavioral problems (OR = 3.0 [1.0-9.0]) strongly related to experiencing a higher caregiver burden. Lastly, social isolation (OR = 3.2 [1.2-8.1]) and psychological symptoms (OR = 8.1 [2.8-23.7]) were red flags for worries for faster cognitive decline. Conclusion: Not only symptomatic patients, but also cognitively normal patients express worries for faster cognitive decline and psychological symptoms. Moreover, we identified patients who are at risk of adverse outcomes of the corona measures, i.e., discontinued care, social isolation, psychological and behavioral problems. This underlines the need for health care professionals to provide ways to warrant the continuation of care and support (informal) networks surrounding patients and caregivers to mitigate the higher risk of negative psychosocial effects.

Project description:BACKGROUND:Discrimination between early-stage dementia and other cognitive impairment diagnoses is central to enable appropriate interventions. Previous studies indicate that dual-task testing may be useful in such differentiation. The objective of this study was to investigate whether dual-task test outcomes discriminate between groups of individuals with dementia disorder, mild cognitive impairment, subjective cognitive impairment, and healthy controls. METHODS:A total of 464 individuals (mean age 71?years, 47% women) were included in the study, of which 298 were patients undergoing memory assessment and 166 were cognitively healthy controls. Patients were grouped according to the diagnosis received: dementia disorder, mild cognitive impairment, or subjective cognitive impairment. Data collection included participants' demographic characteristics. The patients' cognitive test results and diagnoses were collected from their medical records. Healthy controls underwent the same cognitive tests as the patients. The mobility test Timed Up-and-Go (TUG single-task) and two dual-task tests including TUG (TUGdt) were carried out: TUGdt naming animals and TUGdt months backwards. The outcomes registered were: time scores for TUG single-task and both TUGdt tests, TUGdt costs (relative time difference between TUG single-task and TUGdt), number of different animals named, number of months recited in correct order, number of animals per 10?s, and number of months per 10?s. Logistic regression models examined associations between TUG outcomes pairwise between groups. RESULTS:The TUGdt outcomes "animals/10?s" and "months/10?s" discriminated significantly (p <?0.001) between individuals with an early-stage dementia diagnosis, mild cognitive impairment, subjective cognitive impairment, and healthy controls. The TUGdt outcome "animals/10?s" showed an odds ratio of 3.3 (95% confidence interval 2.0-5.4) for the groups dementia disorders vs. mild cognitive impairment. TUGdt cost outcomes, however, did not discriminate between any of the groups. CONCLUSIONS:The novel TUGdt outcomes "words per time unit", i.e. "animals/10?s" and "months/10?s", demonstrate high levels of discrimination between all investigated groups. Thus, the TUGdt tests in the current study could be useful as complementary tools in diagnostic assessments. Future studies will be focused on the predictive value of TUGdt outcomes concerning dementia risk for individuals with mild cognitive impairment or subjective cognitive impairment.

Project description:BackgroundIt is estimated that more than 57 million people have dementia worldwide, and it is one of the leading causes of care dependency in old age. Relatives and other informal caregivers are the most important support for individuals with dementia, but caring for a loved one with dementia may burden the caregiver. Caregiver burden may have adverse outcomes for both the informal caregiver and the care recipient, including decreased quality of life. Caregiver burden is associated with several factors concerning the informal caregiver, the care recipient, and relational and other contextual factors. The aim of this study was to explore which factors are associated with informal caregivers' subjective burden when caring for individuals living at home with dementia.MethodsThis study was a cross-sectional survey among informal caregivers of home-dwelling individuals with dementia in all five geographical regions of Norway. There were 540 informal caregivers who participated, 415 of whom were included in the regression analyses. Caregivers' subjective burden was assessed with the Relatives' Stress Scale. Covariates included were classified into four levels: individual (twofold: informal caregiver and person with dementia), relational, community, and time. Linear multivariable regression analyses were used to identify associations between subjective burden and included factors.ResultsSeveral covariates were statistically significantly associated with subjective burden at the four levels. These covariates included self-rated health, mental distress, age, coping through resignation and denial, emotional and instrumental support, substance use, and humor at the informal caregiver level; behavioral and psychological symptoms of dementia, dementia severity, and degree of disability at the care recipient level; the extent of care, being the primary caregiver, and previous relationship satisfaction at the relational context level; and informal caregivers spending time with friends, leisure activities, social restriction, and knowledge of available health services at the community context level.ConclusionsInformal caregivers' mental distress and care recipients' neuropsychiatric symptoms were the factors with the strongest association with subjective burden.
