Cognitive behavioural therapy and third-wave approaches for anxiety and related disorders in older people.

BACKGROUND: Cognitive behavioural therapy (CBT) is the most researched psychological therapy for anxiety disorders in adults, and known to be effective in this population. However, it remains unclear whether these results apply to older adults, as most studies include participants between 18 and 55 years of age. This systematic review aims to provide a comprehensive and up-to-date synthesis of the available evidence on CBT and third wave approaches for older adults with anxiety and related disorders. OBJECTIVES: To assess the effects of Cognitive Behavioural Therapy (CT, BT, CBT and third-wave CBT interventions) on severity of anxiety symptoms compared with minimal management (not providing therapy) for anxiety and related disorders in older adults, aged 55 years or over. To assess the effects of CBT and related therapies on severity of anxiety symptoms compared with other psychological therapies for anxiety and related disorders in older adults, aged 55 years or over. SEARCH METHODS: We searched the Cochrane Common Mental Disorders Controlled studies Register (CCMDCTR), CENTRAL, Ovid MEDLINE, Ovid Embase and Ovid PsycINFO to 21 July 2022. These searches were updated on 2 February 2024. We also searched the international studies registries, including Clinicalstudies.gov and the WHO International Clinical Trials Registry Platform (ICTRP), to identify additional ongoing and unpublished studies. These sources were manually searched for studies up to 12 February 2024. SELECTION CRITERIA: We included randomised controlled trials (RCTs) in older adults (≥ 55 years) with an anxiety disorder, or a related disorder, including obsessive compulsive disorder (OCD), acute stress disorder and post-traumatic stress disorder (PTSD), that compared CBT to either minimal management or an active (non-CBT) psychological therapy. Eligible studies had to have an anxiety-related outcome. DATA COLLECTION AND ANALYSIS: Several authors independently screened all titles identified by the searches. All full texts were screened for eligibility according to our prespecified selection criteria. Data were extracted and the risk of bias was assessed using the Cochrane tool for RCTs. The certainty of evidence was evaluated using GRADE. Meta-analyses were performed for outcomes with quantitative data from more than one study. MAIN RESULTS: We included 21 RCTs on 1234 older people allocated to either CBT or control conditions. Ten studies focused on generalised anxiety disorder; others mostly included a mix of clinical diagnoses. Nineteen studies focused on the comparison between CBT and minimal management. Key issues relating to risk of bias were lack of blinding of participants and personnel, and participants dropping out of studies, potentially due to treatment preference and allocation. CBT may result in a small-to-moderate reduction of anxiety post-treatment (SMD -0.51, 95% CI -0.66 to -0.36, low-certainty evidence). However, compared to this benefit with CBT immediately after treatment, at three to six months post-treatment, there was little to no difference between CBT and minimal management (SMD -0.29, 95% CI -0.59 to 0.01, low-certainty evidence). CBT may have little or no effect on clinical recovery/ improvement post-treatment compared to minimal management, but the evidence is very uncertain (RR 1.56, 95% CI 1.20 to 2.03, very low-certainty evidence). Results indicate that five people would need to receive treatment for one additional person to benefit (NNTB = 5). Compared to minimal management, CBT may result in a reduction of comorbid depression symptoms post-treatment (SMD -0.57, 95% CI -0.74 to -0.40, low-certainty evidence). There was no difference in dropout rates post-treatment, although the certainty of the evidence was low (RR 1.19, 95% CI 0.80 to 1.78). Two studies reported adverse events, both of which related to medication in the control groups (very low-certainty evidence, no quantitative estimate). Only two studies compared CBT to other psychological therapies, both of which only included participants with post-traumatic stress disorder. Low-certainty evidence showed no difference in anxiety severity post-treatment and at four to six months post-treatment, symptoms of depression post-treatment, and dropout rates post-treatment. Other outcomes and time points are reported in the results section of the manuscript. AUTHORS' CONCLUSIONS: CBT may be more effective than minimal management in reducing anxiety and symptoms of worry and depression post-treatment in older adults with anxiety disorders. The evidence is less certain longer-term and for other outcomes including clinical recovery/improvement. There is not enough evidence to determine whether CBT is more effective than alternative psychological therapies for anxiety in older adults.

Temporal dynamics of depression, cognitive performance and sleep in older persons with depressive symptoms and cognitive impairments: a series of eight single-subject studies.

OBJECTIVES: To investigate the presence, nature and direction of the daily temporal association between depressive symptoms, cognitive performance and sleep in older individuals. DESIGN, SETTING, PARTICIPANTS: Single-subject study design in eight older adults with cognitive impairments and depressive symptoms. MEASUREMENTS: For 63 consecutive days, depressive symptoms, working memory performance and night-time sleep duration were daily assessed with an electronic diary and actigraphy. The temporal associations of depressive symptoms, working memory and total sleep time were evaluated for each participant separately with time-series analysis (vector autoregressive modeling). RESULTS: For seven out of eight participants we found a temporal association between depressive symptoms and/or sleep and/or working memory performance. More depressive symptoms were preceded by longer sleep duration in one person (r = 0.39; p < .001), by longer or shorter sleep duration than usual in one other person (B = 0.49; p < .001), by worse working memory in one person (B = -0.45; p = .007), and by better working memory performance in one other person (B = 0.35; p = .009). Worse working memory performance was preceded by longer sleep duration (r = -.35; p = .005) in one person, by shorter or longer sleep duration in three other persons (B = -0.76; p = .005, B = -0.61; p < .001; B = -0.34; p = .002), and by more depressive symptoms in one person (B = -0.25; p = .009). CONCLUSION: The presence, nature and direction of the temporal associations between depressive symptoms, cognitive performance and sleep differed between individuals. Knowledge of personal temporal associations may be valuable for the development of personalized intervention strategies in order to maintain their health, quality of life, functional outcomes and independence.

Anxiety in Late-Life Depression: Determinants of the Course of Anxiety and Complete Remission.

OBJECTIVE: Studies on the course of depression often ignore comorbid anxiety disorders or anxiety symptoms. We explored predictors of complete remission (no depression nor anxiety diagnoses at follow-up) and of the course of comorbid anxiety symptoms. We additionally tested the hypothesis that the course of anxiety disorders and symptoms in depressed patients is explained by negative life-events in the presence of high neuroticism or a low sense of mastery. METHODS: An observational study of 270 patients (≥60 years) diagnosed with major depressive disorder and 2-year follow-up data, who participated in the Netherlands Study of Depression in Older persons (NESDO). Sociodemographic, somatic, psychiatric, and treatment variables were first explored as possible predictors. A multiple logistic regression analysis was used to examine their predictive value concerning complete remission. Subsequently, negative life-events, personality and their interaction were tested as potential predictors. Linear Mixed Models were used to assess whether the personality traits modified the effect of early and recent life-events, and time and their interactions on the course of the anxiety symptoms. RESULTS: A total of 135 of 270 patients achieved complete remission. Depressed patients with a comorbid anxiety disorder at baseline less often achieved complete remission: 38 of 103 (37.0%) versus 97 of 167 (58.1%). The severity of depressive and anxiety symptomatology, the presence of a comorbid anxiety disorder, and a poorer physical health at baseline predicted nonremission. In line with our hypothesis, a less favorable course of self-reported anxiety symptoms was associated with more recent negative life-events, but only among patients with a high level of neuroticism or a low level of mastery. CONCLUSION: Comorbid anxiety in depression as a negative impact on complete remission at 2-year follow-up. The course of anxiety severity seems dependent on the interaction of personality traits and life-events.

The relationship between depression and executive function and the impact of vascular disease burden in younger and older adults.

Background: depression is associated with worse executive function, but underlying mechanisms might differ by age. Aims: to investigate whether vascular disease burden affects the association between depression and executive dysfunction differentially by age. Method: among 83,613 participants of Lifelines (population-based cohort study), linear regression analyses were applied to examine the association between executive function (Ruff Figural Fluency test, dependent variable) and depression according to DSM-IV criteria (Mini International Neuropsychiatric Interview, independent variable). Results: adjusted for demographic characteristics, major depressive disorder was associated with a lower level of executive function in both younger and older adults. Minor depressive disorder was only associated with worse executive function in younger adults. Adding vascular disease burden to the final model with major depressive disorder, reduced this strength of this association by 5.9% in younger and 5.0% in older adults. Conclusions: major depression was associated with worse executive function across the lifespan, but minor depression only in younger adults. The impact of vascular burden on the association did not differ between younger and older adults. Therefore, vascular risk reduction is important in both age groups.

The importance of personality and life-events in anxious depression: from trait to state anxiety.

OBJECTIVES: Anxious depression is associated with severe impairment and bad prognoses. We hypothesize that recent life-events are associated with more anxiety in late-life depression and that this is conditional upon the level of certain personality traits. METHOD: Baseline data of the Netherlands Study of Depression in Older Persons (NESDO) were used. In 333 patients (≥60 years) suffering from a major depressive disorder, anxiety was assessed with the BAI, personality traits with the NEO-FFI and the Mastery Scale, and life-events with the Brugha questionnaire. Multiple linear regression analyses were applied with anxiety severity as dependent and life-events and personality traits as independent variables. RESULTS: 147 patients (44.1%) had recently experienced one or more life-events. The presence of a life-event is not associated with anxiety (p = .161) or depression severity (p = .440). However, certain personality traits interacted with life-events in explaining anxiety severity. Stratified analyses showed that life-events were associated with higher anxiety levels in case of high levels of neuroticism and openness and low levels of conscientiousness or mastery. CONCLUSIONS: In the face of a life-event, personality traits may play a central role in increased anxiety levels in late-life depression.

Defining anxious depression in later life: a scaring heterogeneity in results.

BACKGROUND: Anxiety in depression is challenging as it results in more functional impairment and a worse prognosis. No consensus exists on the definition of anxious depression. METHODS: In 359 older patients with major depressive disorder, we examined the agreement between anxious depression based on different combinations of comorbid anxiety disorders and anxious depression based on high level of anxiety symptoms measured by self-report questionnaires. RESULTS: Agreement between the definitions of anxious depression was poor, as indicated by κ statistics ranging between 0.06 and 0.23. CONCLUSION: Accepted criteria for anxious depression classify completely different patients as being anxious depressed. This may explain inconsistent results of previous studies on anxious depression. Moreover, progress in this research field is hampered, as studies using different definitions cannot be pooled in meta-analyses.

[Acute neuropsychiatry: a confused patient and a puzzled doctor]. / Acute neuropsychiatrie: verwarring bij patiënt en specialist.

BACKGROUND: Anti-NMDA-receptor-encephalitis is a progressive autoimmune disease with significant mortality if left untreated. CASE DESCRIPTION: A 58-year-old man without previous psychiatric or neurologic history presented at the emergency department after brief loss of consciousness at work. Within a few hours, the patient developed acute neuropsychiatric symptoms, including altered levels of consciousness, aggression, incoherence, change in behaviour, and psychomotor agitation. Initially, additional blood, cerebrospinal fluid and EEG tests showed no abnormalities. Over the course of the following days, catatonia, orofacial dyskinesia and autonomic-function disorder developed, eventually with respiratory insufficiency, necessitating transfer to the intensive-care unit. At this stage, the EEG did show abnormalities, and cerebrospinal fluid analysis showed marginal pleocytosis. The patient was treated with intravenous methylprednisolone and immunoglobins. Anti-NMDA-receptor antibodies were present in the blood and cerebrospinal fluid. Screening for malignancy identified small-cell lung carcinoma, for which the patient was treated with cytostatic agents. CONCLUSION: Acute neuropsychiatric symptoms in a middle-aged patient with no psychiatric medical history are suggestive of an underlying somatic cause. Timely recognition and treatment of anti-NMDA-receptor encephalitis is essential to improve the prognosis.

When a patient with depression is feeling sleepy, be aware of sleep apnoea.

A 67-year-old man was referred to an outpatient clinic of geriatric psychiatry because of persistent symptoms of depression and anxiety, accompanied by sleepiness. The latter had been evaluated multiple times in the general practice over several years; each time it was considered to be a symptom of depression. After referral, the patient was diagnosed with severe obstructive sleep apnoea (OSA), comorbid to a depressive and anxiety disorder. Retrospectively, we conclude that affective symptoms accompanying OSA and sleepiness were wrongfully interpreted as depression, but after having led to problems at work, they have triggered psychiatric comorbidity. Treatment of OSA in addition to the psychiatric disorders resulted in a full recovery over time. The delayed diagnosis of OSA has certainly diminished the patient's quality of life and might have precipitated the depressive disorder. Moreover, OSA poses patients at an increased risk of cardiovascular disease, hypertension, stroke and traffic accidents.

Well-being, physical functioning, and use of health services in the elderly with PTSD and subthreshold PTSD.

OBJECTIVE: To measure the impact of PTSD and subthreshold PTSD on daily life functioning, well-being and health care use in a community based-sample of the elderly population in the Netherlands. METHODS: Consequences of PTSD were investigated in an elderly community-based population (LASA study) by comparing three groups: subjects with PTSD, with subthreshold PTSD, and a reference group. Indicators of well-being (loneliness, self-perceived health and satisfaction with life), disability (days spent in bed and disability days) and use of health care (general practitioners, medical specialists, psychiatrists, mental health care, social workers and professional home care) were investigated. RESULTS: In comparison to the reference group, subjects with PTSD or subthreshold PTSD spent more days in bed due to illness and had more disability days, even when corrected for concurring other diseases or functional limitations. They were less satisfied with life in general, used health care for predominantly somatic care and evaluated the care they received to be inadequate. Psychotropic drugs, if prescribed, were predominantly benzodiazepines and seldom antidepressants. CONCLUSIONS: The findings strongly suggest that elderly with either PTSD or subthreshold PTSD suffer grave impairments in daily life, are less satisfied with life and do not receive optimum treatment. Especially elderly with PTSD frequently visit medical specialists but are rarely treated by psychiatrists or other mental health professionals, nor do they receive antidepressant treatment from their GP. Lack of adequate treatment may be the cause of dissatisfaction with the care they receive.

Prevalence and risk factors of posttraumatic stress disorder in older adults.

BACKGROUND: Posttraumatic stress disorder (PTSD) has scarcely been researched in the elderly. There is no population-based information on prevalence and risk factors in older persons. Patients with PTSD are often not recognized or incorrectly diagnosed. As the disorder has great implications for the quality of life, a correct diagnosis and treatment are crucial. Increased knowledge on vulnerability factors for PTSD can facilitate diagnostic procedures and health management in the elderly. METHODS: PTSD cases were found following a two-phase sampling procedure: a random selection of 1,721 subjects were screened and in 422 subjects a psychiatric diagnostic interview was administered. Prevalence of PTSD and subthreshold PTSD were calculated. Vulnerability factors regarding demographics, physical health, personality, social factors, recent distress and adverse events in early childhood were assessed. RESULTS: 6-month prevalence of PTSD and of subthreshold PTSD was 0.9 and 13.1%, respectively. The strongest vulnerability factors for both PTSD and subthreshold PTSD were neuroticism and adverse events in early childhood. CONCLUSIONS: This is the first population-based study on PTSD in older persons. With a 6-month prevalence of almost 1% the disease is not rare. Comparisons with younger populations suggest some accumulation of cases among older people reflecting the chronic risk factors, which are found in this study: neuroticism and adverse events in early childhood.
