Repeated Measurement of Microglia-Dendritic Spine Interactions Using Multi-Photon Imaging.

In recent decades, mounting evidence has shown that microglia play a vital role in maintaining synapses throughout life. This maintenance is done via numerous microglial processes, which are long, thin, and highly motile protrusions from the cell body that monitor their environment. However, due to the brevity of the contacts and the potentially transient nature of synaptic structures, establishing the underlying dynamics of this relationship has proven difficult.

Association between chronic pain and risk of incident dementia: findings from a prospective cohort.

Background: Chronic musculoskeletal pain has been linked to dementia; however, chronic pain typically occurs in multiple sites; therefore, this study was to investigate whether greater number of chronic pain sites is associated with a higher risk of dementia and its subtypes.

Methods: Participants (N = 356,383) in the UK Biobank who were dementia-free at baseline were included. Pain in the hip, knee, back, and neck/shoulder or 'all over the body' and its duration were assessed.

Parkinsonian Hand or Clinician's Eye? Finger Tap Bradykinesia Interrater Reliability for 21 Movement Disorder Experts.

Background: Bradykinesia is considered the fundamental motor feature of Parkinson's disease (PD). It is central to diagnosis, monitoring, and research outcomes. However, as a clinical sign determined purely by visual judgement, the reliability of humans to detect and measure bradykinesia remains unclear.

Examination of the Feasibility, Acceptability, and Efficacy of the Online Personalised Training in Memory Strategies for Everyday Program for Older Adults: Single-Arm Pre-Post Trial.

Background: Memory strategy training for older adults helps maintain and improve cognitive health but is traditionally offered face-to-face, which is resource intensive, limits accessibility, and is challenging during a pandemic. Web-based interventions, such as the Online Personalised Training in Memory Strategies for Everyday (OPTIMiSE) program, may overcome such barriers.

Objective: We report on OPTIMiSE's feasibility, acceptability, and efficacy.

Instruments measuring change in cognitive function in multiple sclerosis: A systematic review.

Background: Multiple sclerosis (MS) is a chronic demyelinating/neurodegenerative disease associated with change in cognitive function (CF) over time. This systematic review aims to describe the instruments used to measure change in CF over time in people with MS (PwMS).

Methods: PubMed, OVID, Web of Science, and Scopus databases were searched in English until May 2021.

Personal and relational changes following deep brain stimulation for treatment-resistant depression: A prospective qualitative study with patients and caregivers.

Objective: Deep brain stimulation (DBS) and whether it alters patient personality is a much-debated topic within academic literature, yet rarely explored with those directly involved. This study qualitatively examined how DBS for treatment-resistant depression impacts patient personality, self-concept, and relationships from the perspectives of both patients and caregivers.

Methods: A prospective qualitative design was used.

The use of virtual reality in screening for preclinical Alzheimer's disease: A scoping review protocol.

Introduction: Preclinical Alzheimer's disease (AD) represents the earliest phase of AD, often years before the onset of mild cognitive impairment (MCI). There is a pressing focus on identifying individuals in the preclinical AD phase to alter the trajectory or impact of the disease potentially. Increasingly, Virtual Reality (VR) technology is being used to support a diagnosis of AD.

'Surrounding yourself with beauty': exploring the health promotion potential of a rural garden appreciation group.

Gardening has the potential to enhance health and well-being, through increased physical activity and social connectedness. However, while much is known about the benefits of garden activities, less is known about the potential health implications of more passive forms of engagement with gardens, for example, viewing gardens. In addition, much garden research is undertaken in urban settings, leaving little known about potential health impacts for rural populations.

The Drivers of Conversations About Dementia Risk Reduction: A Qualitative Study.

Dementia prevention is an area of health where public knowledge remains limited. A growing number of education initiatives are attempting to rectify this, but they tend to reach audiences of limited size and diversity, limiting intervention-associated health equity. However, initiative participants tend to discuss these initiatives and the information they contain with members of their social network, increasing the number and diversity of people receiving dementia risk reduction information.

Cluster-randomised trial of the Effectiveness of Quality Incentive Payments in General Practice (EQuIP-GP): Prescribing of medicines outcomes.

Background: The Effectiveness of Quality Incentive Payments in General Practice (EQuIP-GP) study investigated whether targeted financial incentives promoting access to a preferred general practitioner, post-hospitalisation follow-up and longer consultations, increase patient-perceived relational continuity in primary care. Secondary outcomes included the use of medicines.

Objective: To evaluate whether introducing a general practice-level service model incorporating enrolment and continuous and graded quality improvement incentives influenced the total prescriptions written and potentially inappropriate prescribing of medicines.

Seeing Neurodegeneration in a New Light Using Genetically Encoded Fluorescent Biosensors and iPSCs.

Neurodegenerative diseases present a progressive loss of neuronal structure and function, leading to cell death and irrecoverable brain atrophy. Most have disease-modifying therapies, in part because the mechanisms of neurodegeneration are yet to be defined, preventing the development of targeted therapies. To overcome this, there is a need for tools that enable a quantitative assessment of how cellular mechanisms and diverse environmental conditions contribute to disease.

Developing the Occupational Communion Scale: Belonging-Based Social Connections Are Vital for Work Engagement, Self-Efficacy, and Positive Affect in Aged Care Workforces.

Background And Objectives: A multifaceted construct called occupational communion (OC), defined as a sense of belonging based on social interaction at work, has been proposed to understand why care workers were positively engaged in their jobs over time, even though they were very demanding. Rich qualitative data on the multiple aspects of OC in care work exist, but a valid measure does not.

Research Design And Methods: We applied a mixed-method systematic scale development process to measure OC.

Modifiable Risk Factors for Dementia Among Migrants, Refugees and Asylum Seekers in Australia: A Systematic Review.

While the prevalence of non-communicable disease risk factors is understood to be higher among migrants than for people born in host nations, little is known about the dementia risk profile of migrants, refugees and asylum seekers. This systematic review examines published literature to understand what is currently reported about 12 identified modifiable risk factors for dementia among migrants, refugees, and asylum seekers residing in Australia. Three literature databases (PubMed/CINAHL/MEDLINE) were systematically searched to find articles reporting excessive alcohol consumption, traumatic brain injury, air pollution, lack of education, hypertension, hearing impairment, smoking, obesity, depression, physical inactivity, diabetes, and limited social contact in Australia's migrant, refugee and asylum seeker population samples.

Clinicians' implicit and explicit attitudes about the legitimacy of functional neurological disorders correlate with referral decisions.

Objectives: Uncertainty regarding the legitimacy of functional neurological disorder (FND) remains among some health care professionals. Despite treatment guidelines and consensus recommendations, variability in clinical practice referral decisions persists. Evidence from other conditions suggests such clinical decision making is impacted by practitioners' implicit and explicit attitudes.

Leading mediators of sex differences in the incidence of dementia in community-dwelling adults in the UK Biobank: a retrospective cohort study.

Background: Little is known regarding whether sex assigned at birth modifies the association between several predictive factors for dementia and the risk of dementia itself.

Methods: Our retrospective cohort study included 214,670 men and 214,670 women matched by age at baseline from the UK Biobank. Baseline data were collected between 2006 and 2010, and incident dementia was ascertained using hospital inpatient or death records until January 2021.

Real-time automated detection of older adults' hand gestures in home and clinical settings.

Unlabelled: There is an urgent need, accelerated by the COVID-19 pandemic, for methods that allow clinicians and neuroscientists to remotely evaluate hand movements. This would help detect and monitor degenerative brain disorders that are particularly prevalent in older adults. With the wide accessibility of computer cameras, a vision-based real-time hand gesture detection method would facilitate online assessments in home and clinical settings.

Let families decide: Barriers and enablers to participation in family-assisted therapy for older people in transition care.

Objective: To understand the barriers and enablers to participation in family-assisted therapy for older people in Transition Care.

Methods: A qualitative study, underpinned by interpretive description, was conducted at two public health services in Melbourne, Australia. Participants included patients in Transition Care, or their family members, who either participated in or chose not to participate in a family-assisted therapy trial.

Characteristics and value of 'meaningful activity' for people living with dementia in residential aged care facilities: "You're still part of the world, not just existing".

Most residential aged care facilities support residents to participate in activities and the importance of activities that are suited to individual preferences and abilities is widely acknowledged. Participating in activities, including those considered to be 'meaningful' has the potential to improve residents' quality of life. However, what makes activities meaningful for people living with dementia in residential aged care facilities is unclear.

Temporal changes in the microglial proteome of male and female mice after a diffuse brain injury using label-free quantitative proteomics.

Traumatic brain injury (TBI) triggers neuroinflammatory cascades mediated by microglia, which promotes tissue repair in the short-term. These cascades may exacerbate TBI-induced tissue damage and symptoms in the months to years post-injury. However, the progression of the microglial function across time post-injury and whether this differs between biological sexes is not well understood.

Ozone modified hypothalamic signaling enhancing thermogenesis in the TDP-43 transgenic model of Amyotrophic Lateral Sclerosis.

Amyotrophic lateral sclerosis (ALS), a devastating progressive neurodegenerative disease, has no effective treatment. Recent evidence supports a strong metabolic component in ALS pathogenesis. Indeed, metabolic abnormalities in ALS correlate to disease susceptibility and progression, raising additional therapeutic targets against ALS.

Lysosomal alterations and decreased electrophysiological activity in CLN3 disease patient-derived cortical neurons.

CLN3 disease is a lysosomal storage disorder associated with fatal neurodegeneration that is caused by mutations in CLN3, with most affected individuals carrying at least one allele with a 966 bp deletion. Using CRISPR/Cas9, we corrected the 966 bp deletion mutation in human induced pluripotent stem cells (iPSCs) of a compound heterozygous patient (CLN3 Δ 966 bp and E295K). We differentiated these isogenic iPSCs, and iPSCs from an unrelated healthy control donor, to neurons and identified disease-related changes relating to protein synthesis, trafficking and degradation, and in neuronal activity, which were not apparent in CLN3-corrected or healthy control neurons.

Developing a shortened version of the dementia knowledge assessment scale (DKAS-TC) with a sample in Taiwan: an item response theory approach.

Background: The 25-item Dementia Knowledge Assessment Scale (DKAS2) is a widely used tool for measuring knowledge of dementia. To increase the applicability of the Chinese-language version of the tool (DKAS-TC) for the general public, this study aimed to develop a shortened version using the item response theory (IRT) approach.

Methods: A total of 401 participants voluntarily completed a Chinese-language version of the DKAS2 questionnaire (DKAS-TC) at the start of dementia awareness training courses in 2020 and 2021.
