Breaking the links between ageism and health: An integrated perspective
Ageing Res Rev. 2024 Feb 1;95:102212. doi: 10.1016/j.arr.2024.102212. Online ahead of print.ABSTRACTAgeism refers to prejudice, stereotypes or discrimination based on a person's actual or perceived chronological age. While ageism can affect people at all stages of the human lifespan, ageism against older adults has emerged as the most pervasive and potentially harmful. Much is now understood about how ageism can impact older people's health and wellbeing via structural, organisational, and provider level biases that threaten the provision of equitable and ethical healthcare. Negative attitudes about age and ageing also con...

Impact of micronutrients and nutraceuticals on cognitive function and performance in Alzheimer's disease
Ageing Res Rev. 2024 Feb 1;95:102210. doi: 10.1016/j.arr.2024.102210. Online ahead of print.ABSTRACTAlzheimer's disease (AD) is a major global health problem today and is the most common form of dementia. AD is characterized by the formation of β-amyloid (Aβ) plaques and neurofibrillary clusters, leading to decreased brain acetylcholine levels in the brain. Another mechanism underlying the pathogenesis of AD is the abnormal phosphorylation of tau protein that accumulates at the level of neurofibrillary aggregates, and the areas most affected by this pathological process are usually the cholinergic neurons in cortical, su...

The proteinopenia hypothesis: Loss of A β < sub > 42 < /sub > and the onset of Alzheimer's Disease
Ageing Res Rev. 2023 Dec;92:102112. doi: 10.1016/j.arr.2023.102112. Epub 2023 Oct 28.ABSTRACTThe dominant protein-lowering strategy in Alzheimer's Disease (AD) has failed to provide a clinically-meaningful treatment for patients. We hypothesize that the loss of functional, soluble Aβ42 during the process of aggregation into amyloid is more detrimental to the brain than the corresponding accrual of insoluble amyloid.PMID:38270185 | DOI:10.1016/j.arr.2023.102112 (Source: Ageing Research Reviews)
