Objectives: This research addresses dementia and driving cessation, a major life event for affected individuals, and an immense challenge in primary care. In Australia, as with many other countries, it is primarily general practitioners (GPs) who identify changes in cognitive functioning and monitor driving issues with their patients with dementia. Qualitative evidence from studies with family members and other health professionals shows it is a complicated area of practice. However we still know little from GPs about how they manage the challenges with their patients and the strategies that they use to facilitate driving cessation.Methods: Data were collected through five focus groups with 29 GPs at their primary care practices in metropolitan and regional Queensland, Australia. A semi-structured topic guide was used to direct questions addressing decision factors and management strategies. Discussions were audio recorded, transcribed verbatim and thematically analyzed.Results: Regarding the challenges of raising driving cessation, four key themes emerged. These included: (i) Considering the individual; (ii) GP-patient relationships may hinder or help; (iii) Resources to support raising driver retirement; and (iv) Ethical dilemmas and ethical considerations. The impact of discussing driving cessation on GPs is discussed.Conclusions: The findings of this study contribute to further understanding the experiences and needs of primary care physicians related to managing driving retirement with their patients with dementia. Results support a need for programs regarding identification and assessment of fitness to drive, to upskill health professionals and particularly GPs to manage the complex issues around dementia and driving cessation, and explore cost-effective and timely delivery of such support to patients.

The Social Vulnerability Scale (SVS), an informant-report of social vulnerability for older adults, was piloted in a sample of 167 undergraduate students (63 male, 104 female) from the University of Queensland. Participants aged 18A â'A 53 (MA =A 25.53 years, SDA =A 7.83 years) completed the SVS by rating a relative or friend aged â[0/00]50 years (MA =A 71.65 years, SDA =A 12.49 years): either someone with memory problems, stroke, dementia, or other neurological condition (nA =A 85); or a healthy older adult (nA =A 82). Excellent internal consistency and testA â'A retest reliability were demonstrated, and the SVS effectively differentiated healthy older adults from those with a neurological condition based on proxy ratings of social vulnerability. The SVS is a potentially useful adjunct measure of older adults' capacity to reside independently. [ABSTRACT FROM AUTHOR]

Progress in understanding brain/behavior relationships in adult-acquired dysprosody has led to models of cortical hemispheric representation of prosodic processing based on functional (linguistic vs affective) or physical (timing vs pitch) parameters. These explanatory perspectives have not been reconciled, and also a number of neurobehavior syndromes that include dysprosody among their neurological signs have not yet been integrated. In addition to expanding the functional perspective on prosody, some of these syndromes have implicated a significant role of subcortical nuclei in prosodic competence. In this article, two patients with acquired dysprosodic speech following damage to basal ganglia nuclei were evaluated using behavioral, acoustic, cognitive, and radiographic approaches. Selective quantitative measures were performed on each individual's performance to provide detailed verification and clarification of clinical observations, and to test hypotheses regarding prosodic function. These studies, combined with a review of related clinical research findings, exemplify the value of a broader perspective on the neurobehavioral dysfunction underlying acquired adult dysprosodic speech, and lead to a new, proposed conceptual framework for the cerebral representation of prosody.

Objective: To characterize on-the-road, behind-the-wheel driving abilities and related laboratory performances of subjects with mild Alzheimer's disease (AD) and vascular dementia.Design: Prospective, experimental study involving two mild dementia and three age and health control groups. Road test reliability and validity were assessed.Setting: Greater western Los Angeles. Subjects were enrolled from the community by referral and from the Veterans Affairs dementia and diabetes clinics.Participants: Eighty-seven driving subjects were enrolled; 83 completed the study. A sample of eligible dementia clinic subjects consisting of 15 mild AD patients met National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer's Disease and Related Disorders Association probable AD criteria, while 12 met Diagnostic and Statistical Manual of Mental Disorders, Revised Third Edition and Hachinski diagnostic criteria for multi-infarct dementia (vascular dementia). Clinic control subjects consisted of 15 age-matched patients with diabetes and without a history of stroke or dementia. Community controls consisted of 26 healthy, age-matched, older subjects (> 60 years) and 16 young subjects (20 to 35 years).Main Outcome Measures: Drive score from the Sepulveda (Calif) road test and laboratory measures of attention, perception, and memory.Results: The drive scores in the mild AD group (mean, 22.1; SD, 3.8) and in the vascular dementia group (mean, 24.0; SD, 7.8) differed significantly (P < .001 studentized range test) from the drive scores in the diabetic control group (mean, 31.5; SD, 3.9), the older control group (mean, 32.6; SD, 2.8), and the young control group (mean, 33.6; SD, 3.2). Drive score among the three control groups did not vary significantly. Short-term memory (Sternberg), visual tracking, and Folstein Mini-Mental State Examination scores correlated best with drive score, with a cumulative R2 of 0.68. Drive score and number of collisions and moving violations per 1000 miles driven were negatively correlated (r = -0.38; P < .02).Conclusions: Based on this study, type and degree of cognitive impairment are better predictors of driving skills than age or medical diagnosis per se. Specific testing protocols for drivers with potential cognitive impairment may detect unsafe drivers more effectively than using age or medical diagnosis alone as criteria for license restriction or revocation.

Abstract Background There are well-established risk factors, such as lower education, for attrition of study participants. Consequently, the representativeness of the cohort in a longitudinal study may deteriorate over time. Death is a common form of attrition in cohort studies of older people. The aim of this paper is to examine the effects of death and other forms of attrition on risk factor prevalence in the study cohort and the target population over time. Methods Differential associations between a risk factor and death and non-death attrition are considered under various hypothetical conditions. Empirical data from the Australian Longitudinal Study on Women's Health (ALSWH) for participants born in 1921-26 are used to identify associations which occur in practice, and national cross-sectional data from Australian Censuses and National Health Surveys are used to illustrate the evolution of bias over approximately ten years. Results The hypothetical situations illustrate how death and other attrition can theoretically affect changes in bias over time. Between 1996 and 2008, 28.4% of ALSWH participants died, 16.5% withdrew and 10.4% were lost to follow up. There were differential associations with various risk factors, for example, non-English speaking country of birth was associated with non-death attrition but not death whereas being underweight (body mass index < 18.5) was associated with death but not other forms of attrition. Compared to national data, underrepresentation of women with non-English speaking country of birth increased from 3.9% to 7.2% and over-representation of current and ex-smoking increased from 2.6% to 5.8%. Conclusions Deaths occur in both the target population and study cohort, while other forms of attrition occur only in the study cohort. Therefore non-death attrition may cause greater bias than death in longitudinal studies. However although more than a quarter of the oldest participants in the ALSWH died in the 12 years following recruitment, differences from the national population changed only slightly.

Abstract Background Declines in cognitive functioning are a normal part of aging that can affect daily functioning and quality of life. This study will examine the impact of an exercise training program, and a combined exercise and cognitive training program, on the cognitive and physical functioning of older adults. Methods/Design Fit Bodies, Fine Minds is a randomized, controlled trial. Community-dwelling adults, aged between 65 and 75 years, are randomly allocated to one of three groups for 16 weeks. The exercise-only group do three 60-minute exercise sessions per week. The exercise and cognitive training group do two 60-minute exercise sessions and one 60-minute cognitive training session per week. A no-training control group is contacted every 4 weeks. Measures of cognitive functioning, physical fitness and psychological well-being are taken at baseline (0 weeks), post-test (16 weeks) and 6-month follop (40 weeks). Qualitative responses to the program are taken at post-test. Discussion With an increasingly aged population, interventions to improve the functioning and quality of life of older adults are particularly important. Exercise training, either alone or in combination with cognitive training, may be an effective means of optimizing cognitive functioning in older adults. This study will add to the growing evidence base on the effectiveness of these interventions. Trial Registration Australian Clinical Trials Register: ACTRN012607000151437

The article reports on the role of social support in curing the illness of a patient. Research has shown that poorer social networks in older adults can increase the risk of dementia by 60 percent. The positive benefits of companion animals has been long suggested for improving social network. Friends and family may mistakenly believe that not having to care for an animal companion will make life easier for an older adult.

The reported positive outcomes of animal-assisted services have led to an emerging interest in many different aspects of human-animal interactions. The influence of an assistance animal is thought to encompass several psychosocial domains in the life of a person with a significant health impairment. However, little is known about the mechanisms underlying the relationship between Hearing Dogs and their owners. A prospective study design using a written questionnaire method was utilized to survey 58 current and 23 prospective Australian Lions Hearing Dogs owners. The Pet Expectations Inventory (PEI) was used to investigate the anticipated role of Hearing Dogs in waitlisted persons with hearing loss/Deafness, whereas the Lexington Attachment to Pets Scale (LAPS) was completed by current owners to assess emotional attachment. The results revealed a high mean PEI score (M = 73.1, SD = 10.9, Mdn = 73.0, range: 55-91), with prospective owners strongly expecting the role of Hearing Dogs to include companionship/love and security. Furthermore, strong attachment features were evident in the owners' relationships with Hearing Dogs, as demonstrated by a high total LAPS score (M = 81.2, SD = 7.5, range: 63-91). Mean scores for statements within the "people substitution" category were highest (range = 3.6/4.00-3.9/4.00). In this demographically homogenous study cohort, it appeared that the high expectations of potential Hearing Dog owners for their animals to serve supportive roles beyond hearing assistance should be achievable, as evidenced by the strong attachment relationships displayed between Hearing Dogs and their owners.

Objectives: To identify the prevalence of anxiety symptoms using a variety of instruments in an Australian memory clinic sample., Methods: This is an exploratory cross-sectional study using a purposive consecutive series sample of 163 individuals and their carers who attended a Brisbane, Australia, memory clinic in 2012-2015. Descriptive statistics and correlation analyses were performed to explore different approaches to measuring anxiety in the sample, using clinician-rated, self-report and carer-report measures., Results: The mean age of participants was 78 years, nearly 53% were females. Over 70% of participants with mild cognitive impairment (MCI) and dementia ( n  = 163) experienced mild to moderate anxiety per a clinician-rated measure (HAM-A), which moderately correlated with carer-report anxiety (IQAD; r s =.59, p  < .001). Only weak correlations of these measures with self-report anxiety (GAI) were detected., Conclusions: Mild to moderate anxiety symptoms were frequent in memory clinic attendees diagnosed with MCI or dementia using the HAM-A, suggesting experiences of subclinical anxiety symptoms., Clinical Implications: Self- as well as carer-report screening tools should be used in memory clinics in addition to routinely administered neuropsychiatric assessments to support early identification of anxiety symptoms and mapping of available post-diagnostic care pathways for people diagnosed with cognitive impairment.

Objective: To examine the prevalence of dementia and problems associated with ageing in the Torres Strait., Methods: The study was conducted across all 18 island and 5 mainland communities in the Torres Strait and Northern Peninsula Area of Far North Queensland. Participants underwent a comprehensive health assessment and a Geriatrician assessment, which were used to establish consensus diagnoses., Results: A total of 276 Torres Strait residents aged between 45 and 93 participated in the study. The prevalence of dementia in the sample was 14.2%, which was 2.87 times higher than the wider Australian population., Conclusion: Torres Strait Islander peoples share the increased risk of dementia seen in Aboriginal Australians compared to the wider community. This highlights the need for interventions to address this increased dementia risk for Aboriginal and Torres Strait Islander communities., (© 2020 AJA Inc.)

Background: Well-being might be lower among dentistry professionals than other health professionals, and differ by personal, professional and sociodemographic factors. Few studies have considered dentistry academics who have different work roles and functions than clinicians. This exploratory study focused on well-being among dentistry academics and aimed to explore associations with perfectionism, professional factors and sociodemographics., Method: An online survey was carried out with academic staff in Dentistry and Oral Health departments of nine Universities in Australia and New Zealand. Well-being was assessed using the 22-item Psychological General Well-Being Index, with a maximum score of 110 indicating good well-being. Perfectionism was assessed using the 8-item Short Almost Perfect Scale, with a maximum score of 56 and a higher score indicating perfectionism. Twenty items were used to assess professional and 7 items assessed sociodemographic factors. Associations were explored using correlation and multiple linear regression., Results: There was no significant bivariate association between perfectionism and well-being. Multiple linear regression indicated a significant association between hours of undergraduate teaching and psychological well-being, after adjustment for age, gender, income and overall health., Conclusion: This exploratory study showed poor well-being among dentistry academics, particularly in those teaching undergraduate students for more than 6 h/week., (© 2021 Australian Dental Association.)

Background: Giving up driving is a pivotal life event and universal challenge for people living with dementia and their families, and a complex area of clinical practice for health professionals who monitor driving cessation. The best outcomes are for individuals to plan for and eventually cease driving, however with insufficient support programs in place, many avoid the issue until it is reaches a crisis point. This program of research investigates a comprehensive support- and education-based intervention targeted at people living with dementia and their care partners who are managing driving cessation. The primary aim of this research is to determine the effectiveness of the program through a cluster randomized controlled trial., Methods/design: The intervention (CarFreeMe) is an intensive program delivered by a trained health professional that addresses practical and emotional needs relevant to driving cessation. The seven module program is person-centred, covering awareness raising, adjustment, and practical support that is individualized according to geographic location and the particular goals and preferences of participants. A cluster randomized controlled trial will evaluate the effectiveness of the program. Evaluation will take place pre-intervention, immediately following, and three months post-intervention. Clusters are randomized to either intervention or usual treatment. Participants within clusters will be recruited via primary and secondary care clinics, community agencies, service providers, local media, social media, support groups, and word of mouth. The primary outcome measure for persons with dementia and their care partners is lifespace, collected via (i) smartphone GPS technology and (ii) self-reported number of episodes away from home (during the past week). Secondary outcomes include safe alternative transport status, wellbeing, depression, anxiety, and self-efficacy, which will be collected from dyads. Caregiving strain will be collected from care partner/family member only. A process evaluation of the intervention will also be undertaken., Discussion: There is an urgent need for therapeutic approaches to supporting people living with dementia and their families to negotiate the complex decision making involved in deciding to change their approach to driving. The driving cessation intervention may fill an important gap in service delivery to people living with dementia who are adjusting to life without driving., Trial Registration: Australian and New Zealand Clinical Trials Registry ACTRN12618000388213 , 15 March 2018.
