Background: Inflammation and altered lipid dyshomeostasis have been implicated in the pathogenesis of Alzheimer's disease and vascular dementia.
Objective: To determine if there are any associations between dietary patterns, plasma lipid profiles, and inflammatory potential in a vascular dementia cohort.
Methods: One hundred fifty participants (36 subjects with Vascular Dementia and 114 healthy controls) from two Australian teaching hospitals completed a cross-sectional survey examining their dietary and lifestyle patterns.
Objective: WeiNaoKang (or SaiLuoTong) is an herbal formula consisting of ginkgo, ginseng, and saffron. Our objective was to investigate if WeiNaoKang could improve cognitive function and cerebral perfusion in patients suffering from vascular dementia.
Methods: A 16-week randomized double-blind, placebo-controlled trial was carried out in the setting of a memory disorder clinic at a single center.
Plasma biomarkers for Parkinson's disease (PD) diagnosis that carry predictive value for cognitive impairment are valuable. We explored the relationship of Mini-Mental State Examination (MMSE) score with plasma biomarkers in PD patients and compared results to vascular dementia (VaD) and normal controls. The predictive accuracy of an individual biomarker on cognitive impairment was evaluated using area under the receiver operating characteristic curve (AUROC), and multivariate logistic regression was applied to evaluate predictive accuracy of biomarkers on cognitive impairment; 178 subjects (41 PD, 31 VaD and 106 normal controls) were included.

We investigated whether combining plasma levels of α-synuclein, anti-α-synuclein, and/or their ratios to amyloid beta-40 correlated with clinical diagnosis. The inclusion of amyloid beta-40 (Aβ40) is novel.

Recently, the notion that small vessel VaD is caused solely by vascular pathology has been challenged by new evidence of concomitant breakdown of the blood-brain barrier and dysregulation of neuroinflammation in the white matter.
Methods: We examined selected inflammatory cytokines and chemokines in the plasma from patients with small vessel VaD (n = 41) and from age-matched controls (n = 131) using multiplex bead-based assays.
Unlabelled: Fall prevention and management of behavioural and psychological symptoms of dementia (BPSD) in long-term care (LTC) facility is a major challenge. The objective of this systematic review is to assess the evidence of digital technology in their management. All studies of English-language excluding case-reports were eligible for review.

Objectives: We aimed to compare the impact of initial government policies on this vulnerable older population between the UK and Australia during the first wave of attack.
Methods: We searched websites of governments in the UK and Australia and media outlets.

Methods: A retrospective observational cohort study of patients admitted to a single r-TACP unit between 1 January 2014 and 31 December 2017 was carried out. Baseline patient characteristics and discharge outcomes were analyzed.
Objective: The study aimed to survey hospital staff knowledge of the application of the Mental Health Act 2007 (NSW) (MHA) and the Guardianship Act 1987 (NSW) (GA) in the care and treatment of older persons in a teaching hospital in Sydney. Method Over a two-month period in 2017, a survey questionnaire was distributed to staff involved in older persons' care across the hospital.
Results: The majority of the hospital staff demonstrated basic theoretical knowledge of both the GA (76%) and of the MHA (84.
In this mini-review, we summarize recent findings relating to the prion-like propagation of α-synuclein (α-syn) and the development of novel therapeutic strategies to target synucleinopathy in Parkinson's disease (PD). We link the Braak's staging hypothesis of PD with the recent evidence from in-vivo and in-vitro studies for the prion-like cell-to-cell propagation of α-syn (via exocytosis and endocytosis). The classical accumulation of aggregated α-syn in PD may result from an increased production or a failure in the mechanisms of clearance of α-syn.

Despite these known effects, any impact of delirium on the emotional well-being of stroke survivors is unclear. Methods A post hoc analysis was performed on our prospective cohort study of 156 stroke patients.

In this study, we show that α-syn can be taken up by primary human cortical neurons, astrocytes and skin-derived fibroblasts in vitro. Our findings that brain and peripheral cells exposed to α-syn can lead to impaired mitochondrial function, leading to cellular degeneration and cell death, provides additional evidence for the involvement of mitochondrial dysfunction as a mechanism of toxicity of α-syn in human cells.

However, it is well established that PD can generate symptoms of constipation and other gastrointestinal problems and α-syn containing lesions have been identified in intestinal nerve cells. In this study, we show that α-syn can be taken up and accumulate in primary human foetal enteric neurons from the gastrointestinal tract and can be transferred between foetal enteric neurons.

Genes found to be associated with PD through investigating genetic polymorphisms or via the whole genome association studies suggest that such genes could also contribute to an increased risk of PD in the general population. Some environmental factors have been found to be associated with genetic factors in at-risk patients, further implicating the role of gene-environment interactions in sporadic PD.

Between May 28, 2009 and January 30, 2010, we assessed aged care inpatients for risk of falls using the standard STRATIFY fall screening tool and the 2-item self-reported questionnaire developed for this study. The participants were then followed up, with the primary outcome being the occurrence of falls.
