INTRODUCTION
In the United States, an estimated 5.3 million people have Alzheimer’s disease today1; that number is projected to grow to 13.2 million by 20502. In the UK, approximately 700 000 people have some form of dementia, and that number is expected to top 1 million by 20253. Most dementia patients will eventually need some form of care, and informal caregivers (usually family members) provide most of that care. It is estimated that there are about 9 million informal caregivers in the United States1 and 4 million in England3. Family caregiving, although it allows dementia patients to stay in their homes with their loved ones longer and is less financially costly than nursing home care, places an immense strain on the caregivers.
Caregiving is difficult work, and dementia caregiving is partic-ularly stressful4. Dementia family caregivers have higher rates of nearly every form of psychiatric and psychological distress, espe-cially depression – several studies that used psychiatric interviews to evaluate caregivers found that rates of major depressive disorder were around 30% – considerably higher than anticipated in the gen-eral adult population5. Caregivers also report more physical health problems than non-caregivers, and numerous studies have found that compromised immune system function, changes in blood pressure and disrupted HPA axis function are common6. Although these indi-cators of stress are well documented, the development and careful evaluation of theoretically grounded interventions to address these problems and symptoms have been slow. Recent studies have begun to use better methodology and to show significant decreases in care-giver stress and depression. This chapter will describe assessment of caregiver distress, then review evidence-based treatments (EBTs) and other promising approaches emerging in the field today.
Dementia caregiving is stressful for many reasons. Caregivers are watching the inevitable decline of a loved one, often their significant other. They are often elderly themselves and face their own declining health. Family caregivers shoulder the intense burden of daily care activities, ranging from taking over the care recipient’s finances to feeding and toileting. The constantly increasing level of care required over the course of a progressive illness like Alzheimer’s disease deprives caregivers of time for their own activities and opportunities for social support, and can even compromise their jobs and their abil-ity to meet obligations to other family members. Yet many caregivers also feel there are positive aspects of caregiving that tremendously benefit their lives7.
The ‘stress process’ model has guided our understanding of care-giving for almost 20 years9. This model describes how caregivers use resources (both internal and external) to respond to the demands of their caregiving situation and other life circumstances (e.g. job, spouse, children). This process takes place within a sociocultural con-text. Perceived stress is a function of the extent to which demands exceed resources and the requisite coping skills to manage these demands are no longer adequate to the tasks at hand.
One must also take into account such ‘individual difference’ variables as age, gender, ethnicity, relationship and socioeconomic status, which interact with objective stressors and resources and play important roles in determining which caregivers develop physical and/or emotional problems in response to their situations. For example, spousal caregivers are particularly susceptible to depression and stress10. Being female and being married to the care recipient tend to be related to lower levels of both physical health and psychological well-being11. A caregiver’s age is also significant: younger caregivers and non-spouses are more likely to experience role strain, which is usually magnified by lack of resources and perceived intensity of caregiving-related stressors11.
Cultural diversity is another important dimension that adds heuris-tic value to the stress process model. Many studies find that cultural differences affect multiple aspects of caregiving. Racial/ethnic groups vary greatly in how they perceive objective and subjective stressors, the knowledge they have and the use they make of resources, and the kinds of coping skills they prefer to employ to help them manage their situations11–14 .i For example, Caucasian/white caregivers are
iThere is great divergence in empirical findings on cultural differences, and to date there have been only a small number of studies on Asian-American and Hispanic caregivers. In order to give equal balance to each ethnic group and resolve hetero-geneous or conflicting results, we rely here on available meta-analyses and reviews rather than individual studies. Note also that the terms ‘Asian-American’ and ‘His-panic’ refer to very heterogeneous groups in terms of language, cultural heritage and socioeconomic status. These terms are used in this chapter because they are current designations used in the US Census; however, for clinical purposes, information about specific sub-groups is needed to work effectively – rather than relying on broad gen-eralizations that may or may not be accurate or apply to the individual caregiver in your office.
more likely to be married to the care recipient and report higher lev-els of caregiver stress, burden and depression than African-American caregivers14. They tend to use more formal support, such as attending support groups and receiving help from professionals, than non-white caregivers. However, Caucasian/white caregivers also tend to report lower levels of confidence and mastery and less positive appraisal of caregiving compared to ethnic minority caregivers11,13,14.
African-American caregivers often report more role strain, such as more cognitive and physical impairment of the care recipient and a higher number of caregiving tasks, than white caregivers11.Their use of religious coping and their sharing of caregiving responsibili-ties with extended family and non-family members seem to buffer the impact of objective stressors. They express lower subjective burden, higher levels of mastery and greater satisfaction, and fewer depres-sive symptoms than white or Asian caregivers12,13.
Asian-American and Hispanic/Latino caregivers may have lan-guage limitations, strong beliefs in filial obligation and low levels of both acculturation and health literacy. Combined, these factors make caregiving more stressful. Such caregivers are often reluctant to admit their distress openly, relying instead on more indirect means of expression. For example, Chinese-American caregivers tend to present with a high level of somatic complaints; Mexican-American caregivers often present with depression and guilt13. Those who have limited knowledge of English for both reading and writing also have less accurate information about dementia and less access to the health-care system in general and use fewer formal support services than do their Caucasian/white counterparts11.
While cultural beliefs and practices, such as strong family ties and religiosity, can buffer and protect caregivers from negative health outcomes of caregiving, other cultural premises such as filial obli-gation, the priority of family needs over individual needs, and face saving carry special hazards. Many ethnic minority caregivers regard it as shameful or a ‘loss of face’ to admit caregiving-related distress. They are likely to under-report care recipients’ behavioural and other problems, and to be reluctant to use formal services for elderly family members. Asian-Americans and Hispanics, in particular, may have low levels of acculturation, language barriers, and inadequate health literacy, which may lead to cultural isolation and inability to access services that are currently available in the US health-care system.
ASSESSMENT OF FAMILY CAREGIVERS
Current psychiatric practice emphasizes assessment and treatment of the patient with dementia15. We recommend a dyadic focus in which caregivers are also assessed and treated. Dementia family caregivers (across all racial and ethnic groups studied to date) are at risk of poor physical health and increased mortality, depression, anxiety, anger, frustration and feelings of grief and loss. A clinician should first assess a caregiver for serious difficulty in one or more areas; any diagnosable psychiatric disorders should be treated promptly with either pharmacotherapy or psychotherapy.
Existing guidelines suggest a variety of approaches for assess-ing the psychosocial and psychiatric status of the dementia family caregiver15. We suggest reviewing the Family Caregiver Alliance’s recommendations on domains to assess16,17. An easily downloaded ‘kit’ of these resources, including actual measures and the ‘Care-givers Count Too!’ toolkit for practitioners18, is available free from its website. These provide materials needed to follow up problem areas with detailed assessment and begin directing caregivers towards treatment.
Key Domains to Assess
First: Assess the caregiver’s knowledgeofdementia. A crucial part of understanding the disease process is knowledge of what to expect as a caregiver. Practitioners should assess medical knowledge of the dementing illness and familiarity with problems caregivers com-monly face. It is helpful to have brochures on hand to send home with caregivers, and to have a list of specific websites, such as the Family Caregiver Alliance (www.caregiver.org), Alzheimer’s Disease Edu-cation and Referral Center (ADEAR, sponsored by the National Insti-tute on Aging in the US) (www.nia.nih.gov/Alzheimers/), National Alliance for Caregiving (www.caregiving.org), and the national web-site of the Alzheimer’s Association in the US (www.alz.org). Several of these groups provide free, downloadable materials about dementia, managing caregiver stress and handling common behaviour prob-lems, in multiple languages besides English. Local chapters of many of these organizations also offer free support groups.
Second: Assess basicsafetyneedsof both caregiver and care recip-ient. Driving, for instance, is a common safety concern, and care-givers are often grateful for physicians’ insistence that care recipients give up their car keys permanently. Other environmental issues – can the care recipient be safely left alone and for how long? Does he/she smoke? – are also essential points to cover. Hints of abuse by either the caregiver or care recipient are also important targets that must be followed up with referrals to Adult Protective Services or similar agencies whose role is to investigate such claims and seek remedies for the situation.
Third: Assess caregivers’ emotionalandphysicalwell-being.Sev-eral measures are available starting with the brief ‘Caregiver Self-Assessment Questionnaire’19 developed by the American Medical Association as a screening tool for caregiver stress. It is free and downloadable from the AMA website.
The new 16-item Risk Appraisal Measure (RAM) was developed specifically for culturally diverse dementia caregivers and designed to provide a clear view of what treatments are indicated for a par-ticular caregiver20. Short enough to be administered to the caregiver in the waiting room, it addresses depression, burden, self-care and health, social support and patient problem behaviours. It also assesses safety, focusing on risks associated with both caregiver behaviours (those suggesting an abuse risk) and care recipient behaviours (e.g. continued driving). Caregivers’ answers indicate areas for further assessment or treatment. The RAM is available free of charge and can be obtained in English or Spanish from the study authors.
Other common areas to assess are depressive symptoms and extent of perceived burden. Depressive symptoms can be evaluated quickly and reliably using the CES-D scale21 or the Geriatric Depression Scale22. The CES-D measures the frequency of occurrence of com-mon symptoms of depression in the past week. The CES-D is not copyrighted and is available free of charge from numerous online sources.
The Geriatric Depression Scale is widely used in the US and other countries as a screen for depression. It was designed to tap psycho-logical aspects of depression. Its simple ‘yes/no’ response format makes it easy to use with low-literacy caregivers. It is available free of charge and can be downloaded in many languages from the website: www.stanford.edu/?yesavage/GDS.xhtml.
Perceived burden can be assessed using the Zarit Burden Inventory23. Many other scales exist to assess this and other relevant domains, but due to space constraints we cannot describe them all; see citations 15 and 16 for details.
