Clinical treatment reverses attentional deficits in congestive heart failure

BACKGROUND: Congestive heart failure (CHF) is associated with cognitive deficits, particularly of memory and attention. The present study aims to clarify whether clinical treatment can reverse the attentional deficits of patients with CHF. METHODS: A convenience sample of 50 patients with CHF functional class IV and 30 elderly controls were recruited from a teaching hospital in Brazil. Participants received a clinical and cognitive examination that included the Mini-Mental State Examination (MMSE), Cambridge Cognitive Examination of the Elderly (CAMCOG), Digit Span, Digit-Symbol Substitution, and Letter Cancellation test. The cognitive performance of CHF patients was reassessed 6 weeks after the introduction of clinical treatment. RESULTS: Twenty-seven CHF subjects had MMSE<24, compared to only 10 of the controls (p = 0.07). CHF patients also had lower CAMCOG scores (mean = 71.8) than controls (mean = 82.0; p < 0.01). Digit Span, Digit Symbol and Letter Cancellation scores were lower for patients with CHF than controls (p < 0.01). Similarly patients with CHF took longer to complete the Trail Making A (p = 0.07) and B (p < 0.01). CAMCOG scores and left ventricular ejection fraction were moderately correlated (rho = 0.4, p < 0.01). Nineteen patients were lost for follow-up (11 deceased). Clinical treatment was associated with significant improvement of cognitive scores, particularly on the Digit Symbol (p < 0.01) and Letter Cancellation Tests (p < 0.01). Digit Span, Digit Symbol, Letter Cancellation and Trail Making scores of treated CHF patients and controls were similar (p > 0.10). CONCLUSIONS: CHF is associated with deficits in attention and psychomotor speed. These deficits improve with clinical treatment

Can physical activity improve the mental health of older adults?

The world population is aging rapidly. Whilst this dramatic demographic change is a desirable and welcome phenomenon, particularly in view of people's increasing longevity, it's social, financial and health consequences can not be ignored. In addition to an increase of many age related physical illnesses, this demographic change will also lead to an increase of a number of mental health problems in older adults and in particular of dementia and depression. Therefore, any health promotion approach that could facilitate introduction of effective primary, secondary and even tertiary prevention strategies in old age psychiatry would be of significant importance. This paper explores physical activity as one of possible health promotion strategies and evaluates the existing evidence that supports its positive effect on cognitive impairment and depression in later life

The Kimberley assessment of depression of older Indigenous Australians: prevalence of depressive disorders, risk factors and validation of the KICA-dep scale

This study aimed to develop a culturally acceptable and valid scale to assess depressive symptoms in older Indigenous Australians, to determine the prevalence of depressive disorders in the older Kimberley community, and to investigate the sociodemographic, lifestyle and clinical factors associated with depression in this population. Methods Cross-sectional survey of adults aged 45 years or over from six remote Indigenous communities in the Kimberley and 30% of those living in Derby, Western Australia. The 11 linguistic and culturally sensitive items of the Kimberley Indigenous Cognitive Assessment of Depression (KICA-dep) scale were derived from the signs and symptoms required to establish the diagnosis of a depressive episode according to the DSM-IV-TR and ICD-10 criteria, and their frequency was rated on a 4-point scale ranging from ‘never’ to ‘all the time’ (range of scores: 0 to 33). The diagnosis of depressive disorder was established after a face-to-face assessment with a consultant psychiatrist. Other measures included sociodemographic and lifestyle factors, and clinical history. Results The study included 250 participants aged 46 to 89 years (mean±SD = 60.9±10.7), of whom 143 (57.2%) were women. The internal reliability of the KICA-dep was 0.88 and the cut-point 7/8 (non-case/case) was associated with 78% sensitivity and 82% specificity for the diagnosis of a depressive disorder. The point-prevalence of a depressive disorder in this population was 7.7%; 4.0% for men and 10.4% for women. Heart problems were associated with increased odds of depression (odds ratio = 3.3, 95% confidence interval = 1.2,8.8). Conclusions The KICA-dep has robust psychometric properties and can be used with confidence as a screening tool for depression among older Indigenous Australians. Depressive disorders are common in this population, possibly because of increased stressors and health morbidities

Reducing depression during the menopausal transition: Study protocol for a randomised controlled trial

Background: The menopausal transition (MT) is a biological inevitability for all ageing women that can be associated with changes in mood, including depressive symptoms. There is tentative evidence that women who develop depression during the MT have greater risk of subsequent depressive episodes, as well as increased health morbidity and mortality. Thus, preventing depression during the MT could enhance both current and the future health and well-being of women. This study aims to test the efficacy of a client-centred health promotion intervention to decrease the 12-month incidence of clinically significant symptoms of depression among women undergoing the MT.Methods/Design: This randomised controlled trial will recruit 300 women undergoing the MT living in the Perth metropolitan area. They will be free of clinically significant symptoms of depression and of psychotic or bipolar disorders. Consenting participants will be stratified for the presence of subsyndromal symptoms of depression and then randomly assigned to the intervention or control group. The intervention will consist of eight telephone health promotion sessions that will provide training in problem solving and education about the MT, healthy ageing, depression and anxiety, and management of chronic health symptoms and problems. The primary outcome of interest is the onset of a major depressive episode according the DSM-IV-TR criteria during the 12-month follow-up or of clinically significant symptoms of depression, as established by a score of 15 or greater on the Patient Health Questionnaire (PHQ-9). Secondary outcomes of interest include changes in the severity of symptoms of depression and anxiety (Hospital Anxiety and Depression Scale, HADS), quality of life (Short Form Health Survey, SF-12), and lifestyle.Discussion: Current evidence shows that depressive symptoms and disorders are leading causes of disability worldwide, and that they are relatively common during the MT. This study will use a multifaceted health promotion intervention with the aim of preventing depression in these women. If successful, the results of this trial will have implications for the management of women undergoing the MT.

Australian older adults\u27 views on using social media for reducing social isolation and loneliness in hearing impaired older adults: A community conversation

Objective(s): The objective of this study was to conduct a community conversation to identify the views of the community members when designing an online community using Facebook to support the psychosocial well-being of hearing-impaired older adults. Methods: A community conversation was held with 40 older adults aged more than 60 years. The participants were divided into groups of five and asked to discuss three open-ended questions. The researchers facilitated the discussions. Results: The overwhelming response from this group was that they did not use Facebook or social media as a tool for social connection and did not see the benefits of social media applications. They preferred phone calls or in-person events to maintain their social relationships. Conclusions: Implications for areas of future research and interventions that target loneliness in older adults are discussed

Affective disorders, psychosis and dementia in a community sample of older men with and without Parkinson's disease

Background: Dementia and affective and psychotic symptoms are commonly associated with Parkinson's disease, but information about their prevalence and incidence in community representative samples remains sparse. Methods: We recruited a community-representative sample 38173 older men aged 65-85 years in 1996 and used data linkage to ascertain the presence of PD, affective disorders, psychotic disorders and dementia. Diagnoses followed the International Classification of Disease coding system. Age was recorded in years. Follow up data were available until December 2011. Results: The mean age of participants was 72.5 years and 333 men (0.9%) had PD at study entry. Affective and psychotic disorders and dementia were more frequent in men with than without PD (respective odds ratios: 6.3 [95%CI = 4.7, 8.4]; 14.2 [95%CI = 8.4, 24.0] and 18.2 [95%CI = 13.4, 24.6]). Incidence rate ratios of affective and psychotic disorders were higher among men with than without PD, although ratios decreased with increasing age. The ageadjusted hazard ratio (HR) of an affective episode associated with PD was 5.0 (95%CI = 4.2, 5.9). PD was associated with an age-adjusted HR of 8.6 (95%CI = 6.1, 12.0) for psychotic disorders and 6.1 (95%CI = 5.5, 6.8) for dementia. PD and dementia increased the HR of depressive and psychotic disorders. Conclusions: PD increases the risk of affective and psychotic disorders, as well as dementia, among community dwelling older men. The risk of a recorded diagnosis of affective and psychotic disorders decreases with increasing age

Mortality in a cohort of remote-living aboriginal Australians and associated factors

Objectives: We aimed to describe mortality in a cohort of remote-living Aboriginal Australians using electronic record linkage. Methods: Between 2004 and 2006, 363 Aboriginal people living in remote Western Australia (WA) completed a questionnaire assessing medical history and behavioural risk factors. We obtained mortality records for the cohort from the WA Data Linkage System and compared them to data for the general population. We used Cox proportional hazards regression to identify predictors of mortality over a 9-year follow-up period. Results: The leading causes of mortality were diabetes, renal failure, and ischaemic heart disease. Diabetes and renal failure accounted for 28% of all deaths. This differed from both the Australian population as a whole, and the general Indigenous Australian population. The presence of chronic disease did not predict mortality, nor did behaviours such as smoking. Only age, male sex, poor mobility, and cognitive impairment were risk factors. Conclusions: To reduce premature mortality, public health practitioners should prioritise the prevention and treatment of diabetes and renal disease in Aboriginal people in remote WA. This will require a sustained and holistic approach

Prevalence of mental disorders among older Australians: Contrasting evidence from the 2020–2021 National Study of Mental Health and Wellbeing among men and women and the Health In Men Data Linkage Study

Objective: To determine the prevalence of common mental disorders among older Australians included in the Health In Men Data Linkage Study and compare those with the results of the 2020–2021 National Study of Mental Health and Wellbeing (NSMHW). Method: We used longitudinal record linkage to estimate the prevalence of mental disorders from age 65 years in a random sample of 38173 Australian men aged 65–85 years living in the Perth metropolitan region. Outcome was the proportion of participants affected by depressive episodes or dysthymia, bipolar disorder, anxiety disorder, psychotic disorder and alcohol use disorder. Results: Prevalence estimates for participants aged 65–69, 70–74, 75–79, 80–84 and ≥85 years were 0.9%, 2.0%, 3.6%, 5.8% and 12.6% for depressive, 0.2%, 0.3%, 0.4%, 0.4% and 0.7% for bipolar, 0.1%, 0.5%, 1.3%, 2.2%, 6.9% for anxiety, 0.2%, 0.4%, 0.5%, 0.4% and 0.6% for psychotic and 1.2%, 1.7%, 2.1%, 2.2% and 4.2% for alcohol use disorders. Conclusions: In contrast to the NSMHW, our data indicate that the prevalence of depressive and anxiety disorders increases with age, particularly among the older old. We conclude that the NSMHW should not be relied upon to guide planning or policies to address the mental health needs of older Australians

Homocysteine, grey matter and cognitive function in adults with cardiovascular disease

Background: Elevated total plasma homocysteine (tHcy) has been associated with cognitive impairment, vascular disease and brain atrophy. Methods: We investigated 150 volunteers to determine if the association between high tHcy and cerebral grey matter volume and cognitive function is independent of cardiovascular disease. Results: Participants with high tHcy (≥15 μmol/L) showed a widespread relative loss of grey matter compared with people with normal tHcy, although differences between the groups were minimal once the analyses were adjusted for age, gender, diabetes, hypertension, smoking and prevalent cardiovascular disease. Individuals with high tHcy had worse cognitive scores across a range of domains and less total grey matter volume, although these differences were not significant in the adjusted models. Conclusions: Our results suggest that the association between high tHcy and loss of cerebral grey matter volume and decline in cognitive function is largely explained by increasing age and cardiovascular diseases and indicate that the relationship is not causal

Falls, Depression and antidepressants in Later Life: A Large Primary Care Appraisal

Background: Depression and falls are common and co-exist for older people. Safe management of each of these conditions is important to quality of life. Methods: A cross-sectional survey was used to examine medication use associated with injurious and non-injurious falls in 21,900 community-dwelling adults, aged 60 years or over from 383 Australian general practices recruited for the DEPS-GP Project. Falls and injury from falls, medication use, depressive symptoms (Primary Health Questionnaire (PHQ-9)), clinical morbidity, suicidal ideation and intent, health status (SF-12 Health Survey), demographic and lifestyle information was reported in a standardised survey. Findings: Respondents were 71.8 years (sd 7.7) of age and 58.4% were women. 24% 11% and 8% reported falls, fall related injury, and sought medical attention respectively. Antidepressant use (odds ratio, OR: 1.46; 95% confidence interval, 95%CI: 1.25, 1.70), questionable depression (5–14 on PHQ OR: 1.32, 95%CI: 1.13, 1.53) and clinically significant symptoms of depression (15 or more on PHQ OR: 1.70, 95%CI: 1.14, 1.50) were independently associated with multiple falls. SSRI use was associated with the highest risk of multiple falls (OR: 1.66, 95%CI: 1.36, 2.02) amongst all psychotropic medications. Similar associations were observed for injurious falls. Over 60% of those with four accumulated risk factors had multiple falls in the previous year (OR: 3.40, 95%CI: 1.79, 6.45); adjusted for other demographic and health factors. Interpretation: Antidepressant use (particularly SSRIs) was strongly associated with falls regardless of presence of depressive symptoms. Strategies to prevent falls should become a routine part of the management of older people with depression
