Objective . To examine the effect of diabetes treatment on change of measures of specific cognitive domains over 4 years. Research Design and Methods . The sample was drawn from a population-based cohort study in Australia (the PATH Through Life Study) and comprised 1814 individuals aged 65–69 years at first measurement, of whom 211 were diagnosed...

Objective To examine the efficacy of body brain life (BBL), a 12-week online dementia risk reduction intervention. Methods BBL was evaluated in a randomized controlled trial in 176 middle-aged adults with >2 risk factors and <2 protective factors for Alzheimer's disease (AD) assessed on a brief screening instrument. Participants were randomized to...
Article
Without preventative strategies, the burden of dementia is likely to increase rapidly worldwide. Primary prevention approaches involve modifying risk factors before symptoms of cognitive impairment develop. This review systematically assesses Randomised Controlled Trials (RCTs) and reviews of RCTs for their effectiveness in primary prevention. We s...

The Australian National University AD Risk Index (ANU-ADRI, http://anuadri.anu.edu.au) is a self-report risk index developed using an evidence-based medicine approach to measure risk of Alzheimer's disease (AD). We aimed to evaluate the extent to which the ANU-ADRI can predict the risk of AD in older adults and to compare the ANU-ADRI to the dement...

Background Disappointing results from clinical trials of disease-modifying interventions for Alzheimer’s dementia (AD), along with reliable identification of modifiable risk factors in mid life from epidemiological studies, have contributed to calls to invest in risk-reduction interventions. It is also well known that AD-related pathological proces...

Alzheimer’s disease (AD) affects approximately 35 million people worldwide. Increasing evidence suggests that many risk factors for AD are modifiable. AD pathology develops over decades. Hence risk reduction interventions require very long follow-ups to show effects on AD incidence. Focussing on AD risk, instead of diagnosis, provides a more realis...

Most older Australians have at least one chronic health condition. The management of chronic disease is associated with potentially severe economic consequences for patients and their households, partially due to the financial burden associated with out-of-pocket costs for medical and health-related care. A questionnaire was mailed to a cross-secti...

To determine the prevalence of patient-initiated aggression toward general practitioners in Australia. A cross-sectional national survey, conducted during February-May 2010, of 3090 GPs in 19 Divisions of General Practice, purposively sampled to represent urban, rural and remote areas. Proportion of GPs experiencing patient-initiated aggression. Ei...

Patient initiated aggression toward general practice staff can cause distress among staff, however, it is unknown how frequently practice staff experience patient aggression in the workplace. The aim of this study is to determine the national prevalence of patient aggression toward general practice staff. A clustered cross sectional survey involvin...

... The searches produced 527 articles in total for screening (figure 1), of which 340 came from a formal database and 187 came from the grey literature. Of the database articles, 45 were read in full to assess for eligibility, and eight dementia prevention reviews (7,(14)(15)(16)(17)(18)(19)(20) were included. We included four (21-24) (Google search n=3, NICE search n=1) articles from the grey literature. ...
... Metformin (1,1-dimethylbiguanide hydrochloride) has been widely used as blood glucose-lowering by inhibiting gluconeogenesis in treatment of type 2 diabetes mellitus (T2DM) patients for 60 decades 22 . Notably, metformin has been shown to have pleiotropic activities against cancer 23 , inflammatory 24 , and also possesses a neuroprotective activity 25 . Interestingly an in vivo study showed that metformin potentially lowers the risk of severe dengue among diabetes patients that use metformin users when compared to non-users 26 . ...
... In addition, they target mid to late-life adults often at an increased risk of developing dementia (e.g., with existing cognitive decline, a family history of dementia, or cardiovascular comorbidities) [8]. Our research team developed and evaluated the first clinical trial to utilize online educational modules as part of the dementia risk reduction intervention [12]. This study found that including a face-to-face component to accompany online modules did not significantly increase intervention efficacy or adherence. ...
... It assesses 11 risk and 4 protective factors for AD and has been validated on three independent cohorts against the Cardiovascular Risk Factors, Aging, and Dementia index. It has been recognized as a primary risk assessment tool in large-scale AD prevention trials (Anstey et al., 2014) and has been utilized in an online AD risk reduction trial in Australia . This tool, which can be administered by healthcare professionals or researchers, enables the assessment of a person's risk of developing dementia and facilitates the provision of targeted interventions to mitigate that risk. ...
... The questionnaire consisted of multiple-choice and open-ended questions aiming to inform the development of a novel dementia risk reduction intervention. Questions related to technology and online learning were informed by our team's extensive experience with digital components of dementia risk reduction interventions (e.g., [12,42,43]). This experience helped to streamline question response options to keep them concise, while the inclusion of 'other' as an open-ended response ensured comprehensive data collection and minimized the risk of bias or incomplete answers. ...
... Therefore, risk personalization for all known modifiable risk and protective factors needs to be further investigated. In the case of dementia, composite modifiable risk scores such as the LIfestyle for BRAin Health (LIBRA) index 8,17 or the Australian National University Alzheimer's Disease Risk Index (ANU-ADRI 18 ) are also relevant to consider due to the syndrome's multifactor etiology. 19,20 These composite risk scores combine the presence or absence of multiple factors into one numeric value that expresses dementia risk. ...
... Patients with CKD should be prepared to pay a considerable amount of money out of pocket for prescriptions [27] because chronic disease management is expensive [28][29][30]. CKD is associated with poverty and other social determinants of health (SDoH), such as social environmental stressors and psychological factors [31]. Financial problems can be linked to physical health, mental health, satisfaction with social activities and relationships, and a declining quality of life [32]. ...
... Patient aggression in general practice can include acts of incivility (hostility, general rudeness and disrespectful behaviour) and violence (physical and sexual abuse) directed towards clinicians and support staff. 8 General practice receptionists experience disproportionately more acts of patient aggression compared with their clinician and practice colleagues, 8 with anecdotal evidence that the COVID-19 pandemic has exacerbated this phenomenon. 9 Despite recognition that every human should be afforded a safe workplace free from physical or psychological harm, 10 there is presently little understanding of how patient aggression is experienced by general practice receptionists, what the impacts are on this group of workers and what support is provided to them to reduce risks and manage the impacts of such acts directed towards them. ...
... Additionally, those who had fewer years in practice were more likely to experience verbal abuse than those with more experience; in the present study, those who had 6 to 10 years of experience had the highest exposure to verbal violence. [26] In this study, according to the HCWs, the offending persons were mostly the patients and their relatives. This is consistent with the findings of Abed et al [8] and some other studies. ...
