World Alzheimer's Day 2021: The Power of Knowledge

World Alzheimer's Day is an international campaign organised by Alzheimer's Disease International to raise awareness and highlight issues faced by people affected by dementia. It takes place every year on September 21st and is the focus of World Alzheimer's Month.

Dementia is one of the biggest challenges we face, with nearly 50 million people living with dementia worldwide. Yet 2 out of every 3 people globally believe there is little or no understanding of dementia in their countries.The impact of World Alzheimer's Month is growing, but the stigmatisation and misinformation that surrounds dementia remains a global problem. To tackle this challenge, we need to collaborate and share best practice with one another.

In support of this year’s theme – ‘Know dementia, know Alzheimer's’ - Elsevier presents a curated, open access collection of over 70 journal articles and book chapters focused on shining a light on the warning signs of dementia and the importance of a timely diagnosis.

Alzheimer's disease (AD) is by far the most prevalent neurodegenerative disease of aging and is a major burden for patients, caregivers, and the overall health care system. The complexity of AD pathophysiology and the lack of deep understanding of disease mechanisms impeded the development of AD therapy. Currently approved treatments for AD only modestly improve cognitive function but do not modify disease course. The lack of pharmacological approaches has led to the consideration of alternative strategies to prevent or to slow down the progression of AD.

Background: Simulation-based experiences provide learning opportunities into the world of people living with dementia, however limited research into its effectiveness exists. Methods: A quasi-experimental design was used to examine the impact of the virtual dementia tour on empathetic thinking, understanding and person care. Study participants included carers and multi-health professionals (n = 223). Results: Empathetic understanding of symptoms, its impact on the provision of person-centred practice were all scored as neutral.

Given the growing interest in systemic design, there is a demand for designerly approaches that can aid practitioners in catalyzing social systems change. The purpose of this research is to develop an initial portfolio of designerly approaches that acknowledges social structures as a key leverage point for influencing social systems. This article presents learnings from experimentation with a host of designerly approaches for shaping social structures and identifies four design principles to guide systemic design practitioners in doing this work.

Based on the joint HCPMMP parcellation method we developed before, which divides the cortical brain into 360 regions, the concept of ordered core features (OCF) is first proposed to reveal the functional brain connectivity relationship among different cohorts of Alzheimer's disease (AD), late mild cognitive impairment (LMCI), early mild cognitive impairment (EMCI) and healthy controls (HC). A set of core network features that change significantly under the specifically progressive relationship were extracted and used as supervised machine learning classifiers.

Objectives: In the face of the SARS-CoV-2 pandemic, people with dementia and their carers are contending with serious challenges to their health and wellbeing, due to risk of severe illness, limiting of social contact and disruption to usual activities. Many forms of support for people with dementia and their carers, including singing groups, have moved online using videoconferencing. Previous research has demonstrated the benefits of group singing, which include cognitive stimulation, meaningful activity and peer support.

Alzheimer's Disease (AD) is a devastating neurodegenerative disorder of the brain, clinically characterised by cognitive deficits that gradually worsen over time. There is, at present, no established cure, or disease-modifying treatments for AD. As life expectancy increases globally, the number of individuals suffering from the disease is projected to increase substantially. Cumulative evidence indicates that AD neuropathological process is initiated several years, if not decades, before clinical signs are evident in patients, and diagnosis made.

Alzheimer's disease (AD) is the foremost cause of dementia among other neurodegenerative diseases, leading to memory loss and cognitive deficits. AD has gained extensive attention in research for exploring possible interventions. One promising field is natural substances and compounds that could provide a wide range of neuroprotection against AD. This study aimed to investigate the possible effects of melatonin (MEL) and resveratrol (RES) in improving memory deficits in a sporadic mouse model of AD. Memory deficit was induced using AlCl3 and d-galactose for generating an AD mouse model.

Background: Alzheimer's disease (AD) is a progressive neurodegenerative disorder of the brain that ultimately results in the death of neurons and dementia. The prevalence of the disease in the world is increasing rapidly. In recent years, many studies have been done to automatically detect this disease from brain signals. Method: In this paper, the Hjorth parameters are used along with other common features to improve the AD detection accuracy from EEG signals in early stages.

Alzheimer's disease (AD) is the commonest neurodegenerative disorder with a wide array of manifestations, courses, and contributing causes. Despite being clinically characterized a long time ago; no treatment has been developed that could improve the pathology or slow down the disease manifestation- so far. Indian Catechu methanolic extract (ICME) has proved to have multiple beneficial effects that support its use in several disorders- especially those with complex etiology.

In the recent past, biomedical domain has become popular due to digital image processing of accurate and efficient diagnosis of clinical patients using Computer-Aided Diagnosis (CAD). Appropriate and punctual disease identification and treatment arrangement directs to enhance superiority of life and improved life hope in Alzheimer Disease (AD) patients. The cutting-edge approaches that believe multimodal analysis have been shown to be efficient and accurate are improved compared with manual analysis.
