Psychotherapy with Older Adults

Chapter 13 Psychotherapy with Older Adults



Adults older than 85 years are the fastest growing age group in the United States. At least 20% of older adults have a psychiatric disorder. Although most reside at home, 89% of those who live in institutions are in nursing homes. It is projected that the number of those 65 years or older with potentially disabling serious mental illness will double to 15 million in 2030 (SAMHSA, 2004). Mortality rates for younger mentally ill patients will decrease, resulting in many mentally ill individuals living into old age. It is also anticipated that aging baby boomers (born between 1946 and 1964), who number 75 million in the United States, will be at greater risk for substance abuse, anxiety disorders, depression, and posttraumatic stress disorder (PTSD) than the current cohort of elders, and the need for these specialty services will increase (Patterson & Jeste, 1999). The 1999 Surgeon General’s report on mental health stressed the growing prevalence of psychiatric disorders among the elderly and the need for evidence-based services (United States Public Health Service, 1999).


This chapter provides the advanced practice psychiatric nurse (APPN) with the foundation for the provision of psychotherapy with the older adult. The chapter addresses the historical context and the role of the advanced practice nurse (APN); training and certification for APPNs who wish to attain further education in the care of this population; the underlying assumptions and principles for psychotherapy with older adults; diagnostic considerations and goals in selecting therapy approaches for late-life psychiatric disorders; the evidence base for specific therapy modalities; and implementation strategies for cognitive-behavioral therapy (CBT), interpersonal therapy (IPT), psychodynamic therapy (PDT), and life review therapy (LRT) with older adults in a variety of settings. The chapter ends with a case illustrating use of the life review.



Historical Context and the Role of the Advanced Practice Nurse


Historically, older adults with mental health problems have relied on their primary care providers for management of all their health needs, but research has shown consistently that primary care providers are not adequately prepared to diagnose and treat mental health disorders, especially those of older adults. The occurrence of mental illness may be underestimated in nonpsychiatric settings because symptoms may be misattributed to physical disorders, normal aging, and cognitive impairment and because of the lack of age-appropriate diagnostic criteria. Illnesses such as depression are often misdiagnosed or undertreated because the comorbidity of somatic and psychiatric illnesses makes accurate diagnosis more difficult.


There have been significant changes in academic and research interests in aging and the elderly in the past few decades. New scientific findings and hypotheses have addressed illness and the concepts of health promotion and preventive medicine to move studies beyond what aging is to what is possible with aging. Understanding potential in relation to aging is profound, because doing so will enable older people to access latent skills and talents in later life and will challenge younger age groups to think in a different way about what is possible in their later years (Cohen, 2000; Vaillant & Mukamal, 2001). The recognition of potential has resulted in renewed interest in research about psychotherapy options and effectiveness for a population that historically has not been a focus of investigation. The relatively recent inclusion of elderly subjects in psychotherapy research has resulted in an evidence base whose strength varies according to modality and diagnosis.


The nurse who works with older adults with mental illness is challenged to integrate psychiatric nursing skills with knowledge of physiologic disorders, the normal aging process, and sociocultural influences on the elderly and their families. Mental health services are provided to this population in a variety of settings, including general and psychiatric hospitals, nursing homes, assisted-living residential centers, outpatient mental health clinics and offices, integrated services within primary care settings, adult daycare programs, senior centers, and the person’s own home.


The advanced practice geropsychiatric nurse should be proficient at assessing patients’ cognitive, affective, functional, physical, and behavioral statuses, as well as their family dynamics. Geropsychiatric nurses must also be knowledgeable about the effects of psychotropic medication on elderly people, although this is beyond the scope of this chapter. Geropsychiatric nurses who have graduate education in psychiatric nursing may provide individual and group psychotherapy and be employed by agencies to help the entire staff to develop therapeutic programs for seniors with psychiatric or behavioral issues (Bartels et al., 2002).



Training and Certification for Advanced Practice Nurses


Due to the demographic imperative of the aging population, there is increasing awareness of the complexity of the needs of older adults and the need for more advanced practice gerontologic and psychiatric nurses to help meet those needs. Graduate certificate and degree programs in gerontologic or psychiatric nursing are more common than programs that integrate geropsychiatric content and roles. APNs are certified by the American Nurses Credentialing Center as gerontologic clinical nurse specialists (GCNSs) or clinical nurse specialists in adult psychiatric-mental health nursing (PMHNCNSs) or psychiatric-mental health nurse practitioners (PMHNPs) in accordance with the American Nurses’ Association (ANA) Scope and Standards for APNs in each specialty. Geriatric nurse practitioners (GNPs) are credentialed by the American Academy of Nurse Practitioners. There is no national certification examination for geropsychiatric nursing.


GCNSs care for older adults in roles as case managers, consultants, researchers, administrators, and educators. GNPs provide primary care independently and collaboratively, treating acute and chronic illnesses common in the older adult population. Both types of gerontologic APNs practice in a variety of clinical settings, including community programs such as adult daycare, home health agencies, hospitals, long-term care facilities, or private offices. Research findings demonstrate that GNPs and GCNSs improve the care of older adults in a variety of settings (Mezey & Fulmer, 2002).


APPNs work as PMHNCNSs or PMHNPs in settings that include inpatient and emergency psychiatric services, outpatient mental health clinics, psychiatric home care, and substance abuse treatment. An analysis of role delineation studies comparing PMHCNS and PMHNP roles found enough commonalities in these roles that a recommendation was made to develop a single APPN examination that would suffice for all APPNs, rather than using the two separate examinations currently offered (APNA, 2006). Unlike GNPs and GCNSs, all APPNs, PMHCNS, and PMHNPs, are required to achieve competency in psychotherapy.


Some APPNs have expertise in both gerontologic and psychiatric nursing, and although few in numbers, they practice in settings where the elderly receive medical and psychiatric care and have been shown to be effective catalysts for improved clinical outcomes (Kaas & Beattie, 2006). The subspecialty of gerontologic mental health nursing was developed in the 1970s. Core content for this specialty was identified in the 1980s by Beverly Baldwin, but few geropsychiatric programs have been developed (Morris & Mentes, 2006).



Underlying Assumptions and Principles


Effective psychotherapy with the elderly relies on underlying assumptions derived from individual, family collective, and systemic issues, which together provide basic principles for geriatric psychotherapy. Review of the material in this section demonstrates that APPNs are uniquely positioned to provide psychotherapy services for older adults.



Functional Issues for the Individual


Functional disability increases with age. Limitations in activities of daily living increase by decade, ranging from 7% of those between the ages of 65 and 74 years to 25% of those 85 years or older. Strategies to address these limitations can be part of the psychotherapy with elders and their caregivers to decrease excess disability (SAMHSA, 2005). Age may be a source of strength from a lifetime of experience, associated wisdom, flexibility, and more mature coping strategies, from which the elder and APN can share a sense of optimism (Knight, 2004).


The impact of cognitive issues on psychotherapy with older adults is extremely important because research has revealed that cognitive deficits are an integral component of all late-life psychiatric disorders and that they significantly impact functional capacity and disability. Multiple studies have revealed that cognitive impairment does not respond to treatment for other disorders, such as depression, and therefore requires simultaneous treatment (Twamley & Harvey, 2006). Cognitive principles suggest the use of psychotherapy interventions targeting cognitive symptoms and taking functional deficits into account through accommodations, such as using shorter sessions, memory aids, summarization of previous sessions, mnemonic devices, reminders, and note taking.


Visual and auditory limitations are common among older adults and can be accommodated in psychotherapy by using large-print materials, ensuring that personal assistive devices are working properly at each session, clearly articulating, and audiotaping sessions for later review and learning at home. Chronic health problems can impact psychotherapy with the elderly. Eighty percent of those 65 years or older have at least one chronic illness. Living with chronic illness can be a topic of psychotherapy as the APN addresses comorbidity, health management strategies, role-playing doctor visits, and medication management. Mobility is critical to a person’s perception of being healthy. Exercise should be encouraged for its beneficial effect on mobility and for its impact on emotions, depression, and sense of well-being. Mobility limitations may impact the elder’s capacity to get to appointments, which may necessitate home visits, transportation arrangements, or integrated models of health services (Miller, 2004).



Caregiver Issues for the Family


Family caregivers are an important component of therapy. Some family caregivers are supportive, and some have prejudices against psychotherapy. In any event, working with the families of an older adult who is in therapy can be very important to the outcome of therapy. Family caregivers require support themselves. Nurse researchers have contributed to our understanding of the relationship between the demands of the role and caregiver outcomes such as burden (Kolanowski & Piven, 2006). Gaps in this literature include an understanding of differences in issues and interventions for caregivers of elders with disorders other than dementia; more individualized, specific interventions and outcome measures; the inclusion of interventions to strengthen caregivers and health; and a better understanding of positive aspects of caregiving (Kolanowski & Piven, 2006).


Most older adults live at home and are cared for by family and friends. These caregivers are primarily women (77%) and older than 50 years; they are almost evenly divided between adult children (45%) and spouses (49%); and 33% are the sole caregiver. Studies of caregivers for persons with Alzheimer’s disease (AD) have been the most extensive and have revealed that caregiving time is significant, 40 to 100 hours per week of providing difficult personal care, with more than 30% being caregivers for 5 years or longer. Caregivers are significantly affected financially and emotionally, with 66% meeting criteria for significant depression (Alzheimers Association, 2006). Whatever the elder’s disorder, challenging behaviors cause significant distress in caregivers. Caregivers’ quality of life is diminished significantly by physical, emotional, social, and financial burdens that may result in caregiver morbidity. Caregiver breaking points include depletion of time resources, patient misidentifications, paranoia, clinical fluctuations, incontinence, and patient sleep-wake cycle variations (Annerstedt et al., 2000).


The burden of caregiving has usually been described and measured in three ways, including the extent of the workload, the difficulty in performing caregiving, and the perceived impact of caregiving on the caregiver’s life. When looking at the perceived impact of caregiving, the emotional burden is considered along with the impact on resources (Montgomery, 2002). Review of the literature on family burden reveals a number of tools. Research is needed to identify their effectiveness across late-life psychiatric disorders. The Burden Scale may be particularly useful in designing more individualized, targeted interventions because it assesses three dimensions of burden. Objective burden assesses the perceived impact of caregiving on tangible aspects of the caregiver’s life. Subjective demand burden assesses the degree to which the caregiver perceives caregiving to be demanding. Subjective emotional demand assesses the emotional impact of caregiving on the caregiver (Montgomery, 2002).


Goals for family caregiver therapy are derived from the position statement of the American Association for Geriatric Psychiatry regarding principles of care for patients with dementia resulting from AD (Lyketsos et al., 2006). Existing scientific evidence and clinical experience have evolved into a treatment model of therapeutic interventions for AD sufferers and their caregivers. Although recommendations were made to treat the needs of AD caregivers, they also address the treatment needs of those caring for elders with chronic and late-onset mental and somatic disorders. These goals include caregiver education, specific problem-solving skills, resource acquisition, long-range planning, emotional support, and respite.


Caregivers perceive the demands and burdens of caregiving differently throughout the caregiving trajectory and differently from each other. It is therefore important to understand current caregiver burden and tailor intervention strategies to address these needs. For caregivers experiencing objective burden, resource acquisition, respite, and long-range planning are most important. For caregivers experiencing subjective demand burden, caregiver education, specific problem-solving strategies, and emotional support are most critical. For caregivers experiencing subjective stress burden, a support group and individual or family psychotherapy may be most helpful (Montgomery, 2002). Evidence includes a study by Farran and associates (2004), which found that building caregiver skills with an information- and support-oriented group decreased caregiver depression.



Cohort Issues


Among the most important considerations for the APPN conducting psychotherapy with older adults is an understanding of cohort effects, or the impact of having been socialized in certain beliefs, attitudes, personality dimensions, and abilities in another era. For example, the current cohort of elders is different from the future cohort of baby boomers (Knight, 2004). The stigma of psychiatric disorders is a significant issue for the current cohort of older adults. This stigma is expressed in an emphasis on physical symptoms, less discussion of emotions, and a preference for primary care rather than specialized mental health care to discuss personal emotional issues. Although elders prefer primary care, these providers have not demonstrated the expertise in recognition of psychiatric disorders presented in terms of physical symptoms. The empowerment and education of older adults, their families, providers, and the public are required to overcome the barriers imposed by stigma (Miller, 2004; SAMHSA, 2005). Outreach and peer support groups can also be effective (Miller, 2004). Members of this cohort usually have fewer years of formal education, but they have a wealth of wisdom from life experience. Psychotherapy may therefore need to be more concrete by offering suggestions, asking about the elder’s past experiences to explain a current situation, avoiding jargon, incorporating the elder’s wisdom, and sharing the APPN’s insights (Knight, 2004). It is important to understand personal and societal history to comprehend the patient’s experience and frame of reference to be able to formulate a meaningful therapeutic relationship and goals.



Societal Issues


Ageism and bias have contributed to a historically pessimistic perspective on the effectiveness of psychotherapy with the elderly. Stigma is a collective and cohort issue. As more accurate information about aging has evolved and as psychotherapy approaches have developed, clinical psychotherapy practice and research have developed over the past 2 decades. This research is yielding an evidence base to support specific therapy approaches for psychiatric disorders in late adulthood and specific information about adapting psychotherapy approaches for older adults. There is a great need for more qualified, specially trained APPNs to provide mental health care, including psychotherapy, to older adults. Because the treatment response may vary according to the living situation and diagnosis of the older adult, there is a need for more time for psychotherapy sessions (Pinquart & Sorenson, 2001). Existing funding streams and service delivery models need to be adapted to meet the need for long-term, community-based treatment, housing, and support (SAMHSA, 2005). Organizational barriers such as therapy time, transportation, and available providers may not match the needs of the current cohort of elders. Of particular concern is the lack of coordination among agencies and providers in the treatment of late-life psychiatric disorders that are complicated by significant comorbidity issues (Jenkins & Laditha, 1998). APNs, certified in psychiatric-mental health or gerontology can make a significant contribution to the emerging elder mental health crisis.



Common Psychiatric Disorders


Challenges in assessing psychiatric symptoms in the elderly include the masking of symptoms by comorbid disorders and medication, difficulty in obtaining an accurate mental health history, age-related variation in symptom presentation, and denial of symptoms. The following sections provide an overview of the significant late-life psychiatric disorders, assessment strategies, goals for psychotherapy, and treatment considerations and efficacy for each of the following geriatric psychiatric disorders: mood disorders, anxiety, schizophrenia, and dementia.

Depression


Depression, including subsyndromal depression, and other mood disorders are common among the elderly but are not a natural aspect of aging. Although rates of remission are comparable, rates of recurrence are greater for ages 65 to 79 years (Mueller et al., 2004). The Depression and Bipolar Support Alliance has indicated that mood disorders are under-recognized, inadequately treated, and under-serviced in older patients. Under-recognition is a particular problem in primary care, the health care setting most often used by the elderly. Diagnosis is confounded by overlapping symptoms of dementia or comorbid medical conditions, vague somatic complaints or nonclassic symptoms, time and staffing constraints, and the stigma of mood disorders. Doses, recovery rates, and clinicians’ expectations for treatment success are often too low (Charney et al., 2003).


Differences in symptoms of depression in the elderly and young adults include an emphasis on physical (e.g., aches, pains) and cognitive symptoms (e.g., memory), as well as changes in sleep, appetite, and use of pain medication. Psychologically, the elderly are more likely to express an exaggerated sense of helplessness, apathy, and emptiness or loneliness, rather than other emotions (Husain et al., 2005). They may also be quite irritable, masking the underlying sense of despair. Older adults tend to withdraw from their activities. Even though they talk less about suicide, elders have seven times the rate of completed suicides, especially older white males, compared with other groups (Shanmugham et al., 2005). Such differences must be addressed in assessment and psychotherapy interventions (Husain et al., 2005).



Assessment


Chapter 4 describes how to conduct a comprehensive history and psychiatric assessment. Specific assessment tools appropriate for the older adult are highlighted here. Different versions of the Geriatric Depression Scale (GDS) are widely used as a screening tool in practice. Given the prevalence of under-recognition, especially in primary care, efforts have been made to devise a quick, reliable, and valid screen such as the AB Clinician Depression Screen (ABCDS), which was derived from the GDS (Molloy et al., 2006). The Montgomery-Åsberg Depression Rating Scale (MADRS) can be used to measure symptom severity over time and the impact of psychotherapy, and it may be more appropriate than the Hamilton Depression Rating Scale (HAM-D) (1960) and Beck Depression Inventory (BDI), which have many somatic items (Linka et al., 2000). Hopelessness appears to be the factor most predictive of suicide and therefore should trigger an assessment of suicidal ideation (Szanto et al., 2001; Uncapher et al., 1998). The Mood Disorder Questionnaire (MDQ) is a 15-item scale to screen for bipolar disorder that is quick and easy to administer and score (Hirschfeld et al., 2000). The Cornell Scale for Depression in Dementia (CSDD) is the most widely used diagnostic scale for depression in dementia. The Young Mania Rating Scale (YMRS) is an 11-item scale used to assess the severity of mania (Young et al., 1978). Table 13-1 lists screening tools for mood disorders.

It is critical to differentiate depression from delirium and dementia. Depression or apathy with mild cognitive impairment often precedes dementia (Janzing et al., 1999). Delirium is an acute confusional state with changes in consciousness, attention, cognition, and perception that develops within hours or days and that tends to fluctuate over the course of the day. Delirium is usually reversible when the underlying somatic or iatrogenic cause is identified and treated. The onset and progression of depression is more rapid than that of dementia, although onset is more rapid in vascular than Alzheimer’s dementia (AD); memory may or may not be impaired. In depression, speech is more likely to be understood; cognitive losses and disabilities are emphasized; and performance on a mental status examination is inconsistent.



Goals


Because of age-related differences, the treatment foci in late-life depression must include symptom reduction to remission, adherence to the health care regimen, relapse recognition and prevention, reduction of the burden of functional disability, and enhancement of psychosocial factors and quality of life (Folks, 2003). Goals of psychotherapy are to understand illness, learn new or different coping skills and warning signals, and manage the illness or symptoms. Frequent therapy themes include grief, isolation, caretaking burden or stress, finding meaning in life, and balancing resources. As with all late-life psychiatric disorders, APNs need to consider working with the elder’s family.



Treatment


Psychotherapy is considered a viable treatment for elders (Landreville et al., 2001). CBT, reminiscence therapy (RT), brief PDT, and a combination of IPT and medication have the most evidentiary support for the treatment of mild to moderate major depression (Mackin & Arean, 2005). Results of randomized, controlled trials suggest that the combination of pharmacologic and psychotherapy interventions, especially IPT, may be more effective than either intervention alone in treating recurrent major depression (Alexopoulos et al., 2001; Bartels et al., 2003; Reynolds et al., 1999; Steffens, 2005). More research is needed on maintenance therapy, the treatment of subsyndromal depression, and special populations, including minorities and those with mid cognitive impairment (Mackin & Arean, 2005). It has been suggested that CBT and RT have the potential to prevent depression in elders who present with risk factors for depression, including bereavement, sleep disturbance, chronic disorders, prior depression, and female gender (Cole, 2005).


These treatment options can be delivered individually or in groups. Psychotherapy is especially useful in the older adults to avoid adverse events from medications and drug interactions. Medical comorbidities and cognitive impairment require adaptations and can negatively impact therapy effectiveness (Birrer & Vemuri, 2004; Lapid & Rummans, 2003). There is much promise in the results of large clinical trials of different models of depression care, including integrated treatment in primary care, enhanced referral, and depression care managers (DCMs). The outcomes of the Primary Care Research in Substance Abuse and Mental Health for the Elderly (PRISM-E), Improving Mood: Promoting Access to Collaborative Treatment for Late-Life Depression (IMPACT), and Prevention of Suicide in Primary Care Elders: Collaborative Trial (PROSPECT) trials may lead to more effective models of care (Oxman et al., 2005).



Bipolar Disorder


Although 5% to 19% of patients presenting to geriatric psychiatrists have bipolar disorder, there is a paucity of treatment outcome studies (Dunn & Rabins, 1996). Psychopathology can be severe and characterized by incomplete responses, further episodes, and high mortality (Young, 2005a). Bipolar mania in late life usually is milder than in younger patients; can present as mixed, dysphoric, or agitated states; and has a higher probability of irritability. Bipolar depression in late life usually manifests with depressed mood; sleep, appetite, and activity level disturbance; and, cognitive impairments, such as executive dysfunction that may mimic dementia (i.e., pseudo-dementia) (Young, 2005a). Primary bipolar disorder may be early onset (i.e., recurring in later years) or late onset (first episode at age ≥50 years). Older adults with secondary bipolar disorder may not have a family history of bipolar disorder, but secondary mania more commonly has a late onset resulting from neurologic disorders and other general medical conditions and from medication-induced mania.



Assessment


It has been well documented that bipolar disorder is underdiagnosed. The MDQ and YMRS can be used for a more thorough assessment if mood swings, mania, or depression is suspected (Box 13-1). Longitudinal assessment is especially important because depression is more prevalent than mania; depression often precedes mania; mania presents with paranoia, agitation, and delusions; and symptoms overlap with other psychotic and cognitive disorders (Sajatovic et al., 2005). Given the high rates of alcohol abuse and suicide among older adults with bipolar disorder, it is important to screen for both. Diagnostic challenges associated with bipolar disorder in older adults include patient underreporting, vague or nonclassic symptoms, comorbid health conditions, and the fact that depressive and manic symptoms can be induced by somatic conditions and medications.




Treatment


Treatment has primarily focused on medications, including mood stabilizers and atypical antipsychotics (Young, 2005b). There have been no controlled psychotherapy trials in geriatric bipolar disorder. There is some empirical support for IPT and CBT (Scott & Todd, 2002). Education of patients and caregivers about bipolar disorder, treatment adherence, health maintenance, and good sleep practices is recommended (Gildengers et al., 2005). Fielding and colleagues (1999) found that a nursing intervention program enhanced adherence. As with other late-life psychiatric disorders, mental health care, whether inpatient, outpatient, or emergency department, is used less than case management services (Depp et al., 2005).



Anxiety Disorders


Anxiety disorder prevalence data underestimate the clinical significance of subsyndromal anxiety states that require intervention and the fact that anxiety disorders are upstaged by major depressive disorder MDD if co-occurring (Flint, 2005). According to the report of the Surgeon General (1999), anxiety disorders are probably the most commonly occurring psychiatric disorders in the elderly. The overall community prevalence of anxiety disorders is estimated to be 11.4%. Generalized anxiety disorder (GAD) is estimated to have a prevalence of almost 17%. Phobias are the second most prevalent anxiety disorders, with rates of 7.3% for specific phobias, 4.1% for agoraphobia, and 1% for social phobia. The least prevalent anxiety disorders include obsessive-compulsive disorder at 1.5% and panic disorder at 0.5%. However, the prevalence of anxiety symptoms not meeting the threshold of a disorder is estimated to be between 17% and 21% in community samples and greater than 40% among chronically ill samples (Brenes et al., 2005; Mehta et al., 2003).


The incidence of PTSD in elderly persons is the same as or less than that of younger persons. However, it is thought that instruments and criteria for anxiety disorders have not been sufficiently validated in this population and that comorbid depression often obscures clarity about diagnosis of anxiety disorders (Wetherell et al., 2005a). Most research of PTSD in elderly persons has examined individuals who are Holocaust survivors or who were prisoners of war during World War II. In these populations, symptoms of PTSD tend to be chronic, persisting into late life in many cases. In one study, spouses of those who had suffered more traumatic experiences and PTSD symptoms in World War II also had more PTSD symptoms (Bramson et al., 2002). This study speaks to the importance of family work and a systems approach for treatment if one partner has suffered significant trauma.


Some anxiety disorders are more likely to occur during late adulthood. These include GAD, agoraphobia, anxious depression, and anxiety associated with medical illnesses. Major depression with associated anxiety is common in older adults (Beekman et al., 2000). Anxiety usually has an earlier onset. Although treatable, it may be difficult because of greater severity and higher suicidality, yielding poorer outcomes (van Hout et al., 2004). Obsessive-compulsive disorder and panic disorder usually have much earlier onset and tend to be more severe and disabling. There are several risk factors for geriatric anxiety, including gender (female), urban living, history of worrying, poor physical health, low socioeconomic status, high-stress life events, depression, and alcoholism.


Somatic symptoms, such as dyspnea, dizziness, chest pain, irritable bowel, heartburn, tremors, initial insomnia, and hypochondriasis, are predominant in older adults experiencing anxiety disorders. Anxiety disorders may also be expressed as irritability, nervousness, trouble concentrating, worry, and fear. It may be difficult to determine whether the symptoms reflect anxiety or an underlying physical cause, such as endocrine imbalance, pulmonary disease, delirium or dementia, or medication side effects or interactions (Burke et al., 2004; Flint, 2005).




Goals


Treatment goals include rapid management of acute anxiety, clinically meaningful symptom improvement, remission and functional recovery, significant increase in quality of life, significant reduction in inappropriate use of primary care, and relapse prevention (Goodman, 2005). Because anxiety commonly manifests somatically in older adults and pharmacologic relief takes time, it is imperative to make concrete suggestions for the management of acute anxiety. Given the prevalence of GAD, the specific worries of the older adult patient must be a focus of psychotherapy.



Treatment


The research support for the use of many interventions for anxiety in the elderly is not as robust as for depression, but based on success in other populations, these interventions may be effective. Behavioral therapy has been used to confront fears and promote habituation through desensitization. Anxiety symptom management has used relaxation training and biofeedback. Supportive individual and group therapy has involved encouragement, listening, reassurance, redirection, and connections. Cognitive restructuring, interpersonal psychotherapy, and psychoeducation have also been used in the treatment of anxiety disorders (Burke et al., 2004).


Wetherell and colleagues (2005a) conducted a review of evidence-based treatment of geriatric anxiety disorders. The results of this review recognized the potential value of CBT and pharmacologic treatments for late-life anxiety disorders, especially GAD. CBT has had a positive response, although lower than for younger adults. Response to pharmacologic treatment seems more robust. Promising practices include CBT enhancements to counteract cognitive changes, attention to quality of life indicators, cognitive limitations as predictors of response, treatment in primary care settings, and CBT based on intolerance of uncertainty. Limitations include samples and settings, a predominant focus on GAD and use of group interventions, and the lack of knowledge about long-term maintenance of treatment effects. Given elders’ preference for primary care settings, the modular intervention for anxiety in older primary care patients offers hope for future treatment (Wetherell et al., 2005b).



Schizophrenia


Elders with early-onset schizophrenia have had a debilitating chronic disorder most of their lives. The course of the disorder is relatively stable, with some changes in symptom intensity; positive symptoms become less prominent, whereas negative symptoms persist. Severity of movement disorders in older patients is greater than in younger patients. Cognitive decline is similar in patients regardless of age, age of onset, or illness duration (Heaton et al., 1994). Depressive symptoms are common in chronic schizophrenia and are linked to physical, social, and financial distress. Demoralization and relapse are also associated with the clinical symptoms of depression. Depression may be a core symptom cluster, by-product of severe psychosis, or independent symptom (Kasckow et al., 2001).


Late-onset schizophrenia occurs after the age of 45 years and accounts for 20% to 25% of elders with schizophrenia. It differs from early-onset disease in that it is more common in women, is mostly a paranoid subtype, and has less severe symptoms, including less severe negative symptoms, less impairment in learning and abstraction or cognitive flexibility, and less affective blunting or personality deterioration, thereby requiring lower doses of antipsychotics (Rabins & Lavrisha, 2003). Up to 20% of elderly patients with schizophrenia may maintain remission (Jeste & Twamley, 2003).





Treatment


There is strong evidence that psychosocial interventions improve patient outcomes in younger patients, although there is a paucity of research with older adults. The evidence base supports family psychoeducation programs, psychosocial skills training, and CBT, which can be effectively used after psychotic symptoms are under control. CBT is used to reduce distress and functional impairment by changing harmful thoughts or beliefs associated with symptoms. Social skills training is a specific approach that focuses on development and reinforcement of skills that are identified in the assessment and needed to live successfully in the community. Granholm and coworkers (2000, 2005, 2006) have been conducting a research program using a CBSST group intervention integrating CBT and social skills training which teaches coping techniques, social functioning skills, problem solving, and compensatory aids for neurocognitive impairments. Psychotherapy should also address reducing symptoms of depression and anxiety and improving cognitive abilities. If left untreated, these symptoms can be problematic for patients as they try to return to their everyday activities.


People with psychiatric disorders have a number of chronic health problems and are often reluctant to be examined or treated by unfamiliar health care providers. The APN plays an important role in coordinating these services and monitoring health care needs. Primary and preventative health care should be included in the coordination of services. Primary care provider visits may need special attention because of the patient’s reluctance to visit busy offices and clinics. Role-playing sessions may increase the patient’s willingness to keep appointments. Health education needs of elders and their family members should be identified and met.
