Interaction of caregiver-expressed emotions and neuropsychiatric symptoms in persons with dementia: a longitudinal cohort study.

ABSTRACT:

Objectives

Neuropsychiatric symptoms (NPS) have a major impact in persons with dementia (PwD). The interaction between the caregiver and the person with dementia may be related to the emergence of NPS. The concept of expressed emotion (EE) is used to capture this dyadic interaction. The aim of the present study is to examine longitudinally the association between EE in caregivers and NPS in PwD living at home.

Design

A longitudinal cohort study with 2 years of follow-up.

Setting

PwD and their informal caregivers living at home in the south of the Netherlands.

Participants

112 dyads of PwD and their caregivers from the MAAstricht Study of BEhavior in Dementia.

Main outcome measures

EE was measured at baseline with the Five-Minute Speech Sample and was used to classify caregivers in a low-EE or high-EE group. Associations between EE and neuropsychiatric subsyndromes (hyperactivity, mood and psychosis) measured with the Neuropsychiatric Inventory (NPI) were analysed over time.

Results

Seventy-six (67.9%) caregivers were classified in the low-EE group and 36 (32.1%) in the high-EE group. There was no difference between the EE groups in mean NPI scores over time. In the high-EE group, hyperactivity occurred more frequently than in the low-EE group at baseline (p=0.013) and at the other time points, but the mean difference was not always significant. There were no differences for the mood and psychosis subsyndromes. PwD with caregivers scoring high on the EE subcategory critical comments had an increased risk of institutionalisation (OR 6.07 (95% CI 1.14 to 32.14, p=0.034)) in comparison with caregivers scoring low on critical comments.

Conclusions

High EE in informal caregivers is associated with hyperactivity symptoms in PwD. This association is likely to be bidirectional. Future studies investigating this association and possible interventions to reduce EE are needed.

Project description:ObjectiveTo test whether the Tailored Activity Program (TAP) reduces dementia-related neuropsychiatric behaviors, promotes activity engagement, and enhances caregiver well-being.DesignProspective, two-group (treatment, wait-list control), randomized, controlled pilot study with 4 months as main trial endpoint. At 4 months, controls received the TAP intervention and were reassessed 4 months later.SettingPatients' homes.ParticipantsSixty dementia patients and family caregivers.InterventionThe eight-session occupational therapy intervention involved neuropsychological and functional testing, selection, and customization of activities to match capabilities identified in testing, and instruction to caregivers in use of activities.MeasurementsBehavioral occurrences, activity engagement, and quality of life in dementia patients; objective and subjective burden and skill enhancement in caregivers.ResultsAt 4 months, compared with controls, intervention caregivers reported reduced frequency of problem behaviors, and specifically for shadowing and repetitive questioning, and greater activity engagement including the ability to keep busy. Fewer intervention caregivers reported agitation or argumentation. Caregiver benefits included fewer hours doing things and being on duty, greater mastery, self-efficacy, and skill enhancement. Wait-list control participants following intervention showed similar benefits for reductions in behavioral frequency and caregiver hours doing things for the patient and mastery. Caregivers with depressed symptoms derived treatment benefits similar to nondepressed caregivers.ConclusionsTailoring activities to the capabilities of dementia patients and training families in activity use resulted in clinically relevant benefits for patients and caregivers. Treatment minimized trigger behaviors for nursing home placement and reduced objective caregiver burden. Noteworthy is that depressed caregivers effectively engaged in and benefited from the intervention.

Project description:BackgroundNeuropsychiatric symptoms (NPS) have been reported to be useful in predicting incident dementia among cognitively normal older persons. However, the literature has not been conclusive on the differential utilities of the various NPS in predicting the subtypes of dementia. This study compared the risks of Alzheimer's and non-Alzheimer's dementia associated with the various NPS, among cognitively normal older persons.MethodsThis cohort study included 12,452 participants from the Alzheimer's Disease Centers across USA, who were ≥ 60 years and had normal cognition at baseline. Participants completed the Neuropsychiatric Inventory-Questionnaire at baseline and were followed up almost annually for incident dementia (median follow-up = 4.7 years). Symptom clusters of NPS-as identified from exploratory and confirmatory factor-analyses-were included in the Cox regression to investigate their associations with incident dementia.ResultsThe various NPS showed independent yet differential associations with incident dementia. Although psychotic symptoms were rarely endorsed by the participants, they predicted much higher risk of dementia (HR 3.6, 95% CI 2.0-6.4) than affective symptoms (HR 1.5, 95% CI 1.2-1.8) or agitation symptoms (HR 1.6, 95% CI 1.3-2.1). Psychotic symptoms predicted all dementia subtypes, while affective and agitation symptoms differentially predicted some subtypes. Across dementia subtypes, psychotic symptoms had relatively higher risk estimates than affective or agitation symptoms, with the risk estimates being particularly high in non-Alzheimer's dementia.ConclusionsAmong cognitively normal individuals, the presence of NPS may warrant greater clinical vigilance as precursors to dementia and its subtypes. The findings highlight the need for further research to enrich our understanding on the neurobiological links between various NPS and dementia subtypes. They may also change the clinical approach in managing late-life psychotic symptoms, requiring a greater emphasis on dementia surveillance in the diagnostic criteria of late-life psychotic disorders.

Project description:IMPORTANCE:Neuropsychiatric behaviors of persons with dementia, including agitation, aggression, and rejection of care, are almost universal; occur throughout the disease process; and have negative consequences for both persons with dementia and their caregivers. Nonpharmacological approaches are now recognized as first-line treatment to address these behaviors. One promising approach is activity tailored to the person's interests, abilities, and physical and social environment. An evidence-based program, New Ways for Better Days: Tailoring Activities for Persons With Dementia and Their Caregivers (TAP), draws on occupational therapy principles (person-environment-occupation fit, activity analysis) to meaningfully engage persons with dementia. OBJECTIVE:This case report describes the TAP protocol and clinical reasoning processes underlying use of tailored activities as a therapeutic modality to address dementia-related neuropsychiatric behaviors. DESIGN:This is a case study of an African-American woman in her 60s caring for her father, age 92, who has severe dementia and multiple behaviors. OUTCOMES AND MEASURES:Primary outcomes in this case report include the person with dementia's engagement in an activity and the reported neuropsychiatric behaviors. In addition, the caregiver's confidence in using activities is reported. These and other measures from the TAP protocol are described in full. RESULTS:After working with an occupational therapist for eight sessions, the person with dementia's engagement in activity increased by 50% and his frequency of vocal disturbance decreased, and the caregiver felt more confident in using activities with her father. CONCLUSION AND RELEVANCE:This case report illustrates how occupational therapists working with families of persons with dementia can use the TAP protocol to help them manage neuropsychiatric behaviors by tailoring activities. WHAT THIS ARTICLE ADDS:Occupational therapists are uniquely qualified to systematically assess the cognitive functioning of persons with dementia, caregivers, and home environments and to integrate this information to derive and implement activities tailored to the person's capacities and context, thereby reducing neuropsychiatric behaviors and increasing engagement in meaningful activity.
