Perspectives of old-age and dementia researchers on communication with policymakers and public research funding decision-makers: an international cross-sectional survey.

Introduction: Society commonly believes that research knowledge is complementary to public decision-making. This study aimed to understand the perspectives and implications of dementia researchers communicating with policymakers and public research decision-makers (public officials).

Methods: This study uses 24 questions from an anonymous, online survey, which was received by 392 members of nine European, Latin American, and United States medical researcher associations/networks in the fields of age-related neurological degeneration and dementia medicine.

Assessment and management of frailty in individuals living with dementia: expert recommendations for clinical practice.

Frailty complicates the care of individuals with dementia, increasing their vulnerability to adverse outcomes. This Personal View presents expert recommendations for managing frailty in individuals with dementia, aimed at health-care providers, particularly those in primary care. We conducted a rapid literature review followed by a consensus process involving 18 international experts on dementia and frailty.

Plasma phosphorylated tau and neuropsychiatric symptoms in dementia with Lewy bodies.

Introduction: Neuropsychiatric symptoms (NPSs) are common in dementia with Lewy bodies (DLB) but their neurobiological mechanisms are poorly understood.

Methods: NPSs and cognition were assessed annually in participants (DLB n = 222; Alzheimer's disease [AD] n = 125) from the European DLB (E-DLB) Consortium, and plasma phosphorylated tau-181 (p-tau181) and p-tau231 concentrations were measured at baseline.

Results: Hallucinations, delusions, and depression were more common in DLB than in AD and, in a subgroup with longitudinal follow-up, persistent hallucinations and NPSs were associated with lower p-tau181 and p-tau231 in DLB.

Proteomic signatures of Alzheimer's disease and Lewy body dementias: A comparative analysis.

Introduction: We aimed to identify unique proteomic signatures of Alzheimer's disease (AD), dementia with Lewy bodies (DLB), and Parkinson's disease dementia (PDD).

Methods: We conducted a comparative proteomic analysis of 33 post mortem brains from AD, DLB, and PDD individuals without dementia focusing on prefrontal, cingulate, and parietal cortices, using weighted gene co-expression network analyses with differential enrichment analysis.

Results: Network modules revealed hub proteins common to all dementias.

The SLaM Brain Health Clinic: remote biomarker enhanced memory clinic for people with mild cognitive impairment within a National Health Service mental health trust.

Background: The novel South London and Maudsley Brain Health Clinic (SLaM BHC) leverages advances in remote consultations and biomarkers to provide a timely, cost-efficient and accurate diagnosis in mild cognitive impairment (MCI).

Aims: To describe the organisation, patient cohort and acceptability of the remote diagnostic and interventional procedures.

Method: We describe the recruitment, consultation set-up, the clinical and biomarker programme, and the two online group interventions for cognitive wellbeing and lifestyle change.

Temporal Muscle Thickness Predicts Mortality and Disability in Older Adults Diagnosed with Mild Dementia.

Background: Sarcopenia contributes to increased hospitalizations, cognitive impairment, falls, and all-cause mortality. Current diagnostic methods, like body Magnetic Resonance Imaging and dual-energy X-ray absorptiometry, are costly and impractical. Notably, there is no standardized approach for assessing sarcopenia in dementia clinics.

Telomere length and cognitive changes in 7,877 older UK adults of European ancestry.

Background: Telomere length (TL) has been linked to cognitive function, decline and dementia. This study aimed to explore whether both measured TL and genetic disposition for TL predict dimensions of cognitive performance in a longitudinal sample of older UK adults.

Methods: We analysed data from PROTECT study participants aged ≥50 years without a dementia diagnosis, who had completed longitudinal cognitive testing.

Functional and connectivity correlates associated with Parkinson's disease psychosis: a systematic review.

Neural underpinnings of Parkinson's disease psychosis remain unclear to this day with relatively few studies and reviews available. Using a systematic review approach, here, we aimed to qualitatively synthesize evidence from studies investigating Parkinson's psychosis-specific alterations in brain structure, function or chemistry using different neuroimaging modalities. PubMed, Web of Science and Embase databases were searched for functional MRI (task-based and resting state), diffusion tensor imaging, PET and single-photon emission computed tomography studies comparing Parkinson's disease psychosis patients with Parkinson's patients without psychosis.

Progress in the Treatment of Alzheimer's Disease Is Needed - Position Statement of European Alzheimer's Disease Consortium (EADC) Investigators.

β-amyloid-targeting antibodies represent the first generation of effective causal treatment of Alzheimer's disease (AD) and can be considered historical research milestones. Their effect sizes, side effects, implementation challenges and costs, however, have stimulated debates about their overall value. In this position statement academic clinicians of the European Alzheimer's Disease Consortium (EADC) discuss the critical relevance of introducing these new treatments in clinical care now.

Regulatory considerations for developing remote measurement technologies for Alzheimer's disease research.

The Remote Assessment of Disease and Relapse – Alzheimer’s Disease (RADAR-AD) consortium evaluated remote measurement technologies (RMTs) for assessing functional status in AD. The consortium engaged with the European Medicines Agency (EMA) to obtain feedback on identification of meaningful functional domains, selection of RMTs and clinical study design to assess the feasibility of using RMTs in AD clinical studies. We summarized the feedback and the lessons learned to guide future projects.

Sports-related concussion not associated with long-term cognitive or behavioural deficits: the PROTECT-TBI study.

Background: The cognitive effects of sports-related concussion (SRC) have been the subject of vigorous debate but there has been little research into long-term outcomes in non-athlete populations.

Methods: This cohort study of UK community-dwelling adults (aged 50-90 years) was conducted between November 2015 and November 2020, with up to 4 years annual follow-up (n=15 214). Lifetime history of concussions was collected at baseline using the Brain Injury Screening Questionnaire.

A randomized, placebo-controlled trial of purified anthocyanins on cognitive function in individuals at elevated risk for dementia: Analysis of inflammatory biomarkers toward personalized interventions.

Background: Dementia poses a significant global health challenge. Anthocyanins neutralize free radicals, modulate signaling pathways, inhibit pro-inflammatory genes, and suppress cytokine production and may thus have positive cognitive effects in people at increased risk of dementia. We aim to investigate the effects of purified anthocyanins on cognitive function in people at increased risk of dementia according to their inflammation status based on blood-based inflammatory biomarkers.

A Randomised, Double-Blind, Placebo-Controlled, Cross-Over Clinical Trial to Evaluate the Biological Effects and Safety of a Polyphenol Supplement on Healthy Ageing.

DailyColors™ is a supplement made up of several phytonutrients that aims to replicate elements from the Mediterranean diet. These include fruit, berry and vegetable extracts that are rich in key phytochemicals such as Quercetin, Catechins, Phloretin, Ellagic Acid, and Anthocyanins. Here, we determined the effects of DailyColors™ on the blood biomarkers associated with the diverse mechanisms implicated in ageing and age-related diseases, including mitochondrial function, inflammation, and oxidative stress, as well as on saliva's DNA methylation pattern.

Limited evidence of a shared genetic relationship between C-reactive protein levels and cognitive function in older UK adults of European ancestry.

Introduction: Previous studies have shown associations between cognitive function and C-reactive protein (CRP) levels in older adults. Few studies have considered the extent to which a genetic predisposition for higher CRP levels contributes to this association.

Methods: Data was analyzed from 7,817 UK participants aged >50 years as part of the PROTECT study, within which adults without dementia completed a comprehensive neuropsychological battery.

Parkinson's disease psychosis associated with accelerated multidomain cognitive decline.

Background: Cognitive deficits are associated with poor quality of life and increased risk of development of dementia in patients with Parkinson's disease (PD) psychosis. The trajectory of cognitive decline in PD psychosis remains however unclear.

Objective: We examined this using data from the Parkinson's Progression Markers Initiative study.

Distinct grey and white matter changes are associated with the phenomenology of visual hallucinations in Lewy Body Disease.

Visual hallucinations in Lewy body disease (LBD) can be differentiated based on phenomenology into minor phenomena (MVH) and complex hallucinations (CVH). MVH include a variety of phenomena, such as illusions, presence and passage hallucinations occurring at early stages of LBD. The neural mechanisms of visual hallucinations are largely unknown.
