INTRODUCTION: Nonpharmacological therapies (NPTs) can improve the quality of life (QoL) of people with Alzheimer's disease (AD) and their carers. The objective of this study was to evaluate the best evidence on the effects of NPTs in AD and related disorders (ADRD) by performing a systematic review and meta-analysis of the entire field. METHODS: Existing reviews and major electronic databases were searched for randomized controlled trials (RCTs). The deadline for study inclusion was September 15, 2008. Intervention categories and outcome domains were predefined by consensus. Two researchers working together detected 1,313 candidate studies of which 179 RCTs belonging to 26 intervention categories were selected. Cognitive deterioration had to be documented in all participants, and degenerative etiology (indicating dementia) had to be present or presumed in at least 80% of the subjects. Evidence tables, meta-analysis and summaries of results were elaborated by the first author and reviewed by author subgroups. Methods for rating level of evidence and grading practice recommendations were adapted from the Oxford Center for Evidence-Based Medicine. RESULTS: Grade A treatment recommendation was achieved for institutionalization delay (multicomponent interventions for the caregiver, CG). Grade B recommendation was reached for the person with dementia (PWD) for: improvement in cognition (cognitive training, cognitive stimulation, multicomponent interventions for the PWD); activities of daily living (ADL) (ADL training, multicomponent interventions for the PWD); behavior (cognitive stimulation, multicomponent interventions for the PWD, behavioral interventions, professional CG training); mood (multicomponent interventions for the PWD); QoL (multicomponent interventions for PWD and CG) and restraint prevention (professional CG training); for the CG, grade B was also reached for: CG mood (CG education, CG support, multicomponent interventions for the CG); CG psychological well-being (cognitive stimulation, multicomponent interventions for the CG); CG QoL (multicomponent interventions for PWD and CG). CONCLUSION: NPTs emerge as a useful, versatile and potentially cost-effective approach to improve outcomes and QoL in ADRD for both the PWD and CG

Prior research has yielded discrepant findings regarding change in caregiver burden or depressive symptoms after institutionalization of persons with dementia. However, earlier studies often included small postplacement samples. In samples of 1,610 and 1,116 dementia caregivers with up to 6 months' and 12 months' postplacement data, respectively, this study identified predictors of change in caregiver burden and depressive symptoms following nursing home admission. Descriptive analyses found that caregivers reported significant and considerable decreases in burden in the 6- and 12-month postplacement panels. A number of variables predicted increased burden and depressive symptoms in the 6- and 12-month postplacement panels. Preplacement measures of burden and depressive symptoms, site (Florida), overnight hospital use, and spousal relationship appear to result in impaired caregiver well-being following nursing home admission. Incorporating more specific measures of stress, considering the influence of health-related transitions, and coordinating clinical strategies that balance caregivers' needs for placement with sustainability of at-home care are important challenges for future research.

OBJECTIVE:Does psychosocial intervention for caregivers whose spouses with Alzheimer disease (AD) are taking donepezil delay nursing home (NH) placement or death of patients? DESIGN/METHODS:Randomized controlled trial with 2 years of active treatment and up to 8.5 years of follow-up (mean: 5.4 years, SD: 2.4). SETTING/METHODS:Outpatients of research clinics in Australia, the United Kingdom, and the United States. PARTICIPANTS/METHODS:One hundred and fifty-five persons with AD and their spouses. INTERVENTION/METHODS:Five sessions of individual and family counseling (+ prn ad hoc counseling) or usual care. MEASUREMENTS/METHODS:Time to institutionalization and death using Cox proportional hazards methods. RESULTS:Over a mean of 5.4 years (SD: 2.4), there were no differences in NH placement or mortality by intervention group, but there were by country, with Australian patients admitted to NHs earlier than U.S. than U.K. patients. CONCLUSION/CONCLUSIONS:Earlier NH admission of Australian compared to U.K. and U.S. subjects may be due to differences in health care, NH systems, availability, and affordability.

This article describes the clinical findings of a study designed to assess the benefit of counseling for couples, one of whom is in the early stage of Alzheimer's disease (AD). We previously reported our findings based on the first 12 couples that enrolled in the study. Based on the treatment of 30 additional couples, we have refined our treatment strategy to include concepts of Gestalt Therapy and Transactional Analysis and identified prevalent issues of concern to this cohort. The study design has remained as described in the earlier article (Epstein et al., 2006), and has proven to be appropriate to meet the goals of this intervention as indicated by our clinical experience and feedback from the participating couples. Case vignettes demonstrate how to conduct the sessions so that the experience of each member of the dyad is validated, while acknowledging the differential impact of the disease on them.

BACKGROUND: Dementia is a major public health problem with enormous costs to society and major consequences for both patients and their relatives. Family members of persons with dementia provide much of the care for older adults with dementia in the community. Caring for a demented relative is not easy and fraught with emotional strain, distress, and physical exhaustion. Family caregivers of dementia patients have an extremely high risk developing affective disorders such as major depression and anxiety disorder. Family meetings appear to be among the most powerful psychosocial interventions to reduce depression in caregivers.An American landmark study reported substantial beneficial effects of a multifaceted intervention where family meetings had a central place on depression in family caregivers as well as on delay of institutionalization of patients. These effects were not replicated in other countries yet. We perform the first trial comparing only structured family meetings with significant others versus usual care among primary family caregivers of community dwelling demented patients and measure the effectiveness on both depression and anxiety in the primary caregiver, both on disorder and symptom levels. METHODS/DESIGN: In this randomized controlled trial effectiveness as well as cost-effectiveness of family meetings is evaluated. The intervention group receives four family meetings with family and close friends of the primary family caregiver of a community dwelling patient with a clinical diagnosis of dementia. Dyads of patients and their primary caregiver are followed up to one year after baseline assessment. The main outcome measures are the incidence of anxiety and depressive disorders assessed with the Mini-International Neuropsychiatric Interview (MINI) and the severity of anxiety and depressive symptoms in caregivers is measured by validated self report instruments: the Centre for Epidemiologic Studies Depression Scale (CES-D) for depression and the anxiety scales of the Hospital Anxiety and Depression scales (HADS) for anxiety. The economic evaluation is performed from a societal perspective. DISCUSSION: By evaluating the effectiveness of only structured family meetings organized in the Netherlands, this study will contribute to the existing literature about the value of psychosocial interventions for dementia caregivers. TRIAL REGISTRATION: Dutch Trial Registry ISRCTN90163486

OBJECTIVES: To determine whether counseling and support reduce the burden and depressive symptoms of spouse caregivers of patients with Alzheimer's disease (AD) during the transition to institutionalization. DESIGN: A randomized, controlled trial of an enhanced counseling and support program for spouse caregivers of persons with AD. Structured interviews were conducted with spouse caregivers at baseline, every 4 months during Year 1, and every 6 months thereafter for up to 16 years. SETTING: Outpatient research clinic in the New York City metropolitan area. PARTICIPANTS: Referred volunteer sample of 406 spouse caregivers of community-dwelling patients with AD enrolled over a 9.5-year period. INTERVENTION: Enhanced counseling and support consisting of six sessions of individual and family counseling, support group participation, and continuous availability of ad hoc telephone counseling. MEASUREMENTS: Outcome measures included burden (modified Zarit Burden Interview) and depressive symptoms (Geriatric Depression Scale). RESULTS: Burden and depressive symptoms were significantly lower for caregivers in the treatment group than for controls receiving usual care at the time of and after institutionalization. Nursing home admission itself significantly reduced burden and depressive symptoms in the intervention and control groups. CONCLUSION: Institutionalization alone can reduce caregiver burden and depressive symptoms, but enhanced counseling provides additional long-term benefits. The results offer some of the first clinical evidence of the benefits of enhanced counseling during the transition to institutionalization for caregivers of people with AD

OBJECTIVE: To evaluate the effectiveness of a combination of cholinesterase inhibitor therapy for patients with Alzheimer disease (AD) and psychosocial intervention, for their spouse caregivers compared with drug treatment alone in three countries simultaneously. DESIGN: Randomized controlled trial. Structured questionnaires were administered at baseline and at regular follow-up intervals for 24 months by independent raters blind to group assignment. SETTING: Outpatient research clinics in New York City, U.S., Manchester, U.K. and Sydney, Australia. PARTICIPANTS: Volunteer sample of 158 spouse caregivers of community dwelling patients with AD. INTERVENTIONS: Five sessions of individual and family counseling within 3 months of enrollment and continuous availability of ad hoc telephone counseling were provided for half the caregivers. Donepezil was prescribed for all patients. MAIN OUTCOME MEASURE: Depressive symptoms of spouse caregivers measured at intake and follow-up assessments for 24 months using Beck Depression Inventory (revised). RESULTS: Depression scores of caregivers who received counseling decreased over time, whereas the depression scores for caregivers who did not receive counseling increased. The benefit of the psychosocial intervention was significant after controlling for site, gender and country was not accounted for by antidepressant use and increased over 2 years even though the individual and family counseling sessions occurred in the first 3 months. CONCLUSION: Effective counseling and support interventions can reduce symptoms of depression in caregivers when patients are taking donepezil. Harmonized multinational psychosocial interventions are feasible. Combined drug and supportive care approaches to the management of people with AD should be a priority
