Cognitive, behavioral, and functional outcomes of suspected mild traumatic brain injury in community-dwelling older persons without mild cognitive impairment or dementia.

Introduction: Traumatic brain injury (TBI) is associated with greater risk and earlier onset of dementia. This study investigated whether later-life changes in subjective cognition and behavior - potential markers of AD - could be observed in cognitively unimpaired older persons with a history of suspected mild TBI (smTBI) earlier in life and whether changes in cognition and behavior mediated the link between smTBI and daily function.

Methods: Data for 1392 participants from the Canadian Platform for Research Online to Investigate Health, Quality of Life, Cognition, Behaviour, Function, and Caregiving in Aging (CAN-PROTECT) were analyzed.

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.
