Background: The increasing prevalence of Alzheimer's disease (AD) and other aging-related dementias as the population ages will have a dramatic impact on both provision of health care and the economy if nothing is done to prevent or delay the onset of AD or to slow its progression.
Methods: A comprehensive review of the literature in several promising areas of inquiry, other than those representing Food and Drug Administration (FDA)-approved AD- or dementia-specific pharmacologic therapies, that may impact the risk or progression of AD and related dementias was undertaken.
Results: Results highlight a number of factors associated with AD and dementia. These include education and occupation, cognitive and leisure activities, exercise, cholesterol and statins, and head trauma.
Conclusions: Factors associated with AD and dementia may have potential as strategies useful in preventing or delaying AD and dementia or slowing its progression. Further research is needed to determine the validity and strength of the associations and to ascertain causality.

Background: Emerging research found air pollution may be associated with incident Alzheimer's disease (AD) and other dementias. However, few studies have examined these associations at the global scale. This study aimed to assess the dynamic associations between ambient air pollution and the burden of AD and other dementias worldwide.

Our understanding of Alzheimer's disease (AD) has transformed from a purely neuronal perspective to one that acknowledges the involvement of glial cells. Despite remarkable progress in unraveling the biology of microglia, astrocytes and vascular elements, the exploration of oligodendrocytes in AD is still in its early stages. Contrary to the traditional notion of oligodendrocytes as passive bystanders in AD pathology, emerging evidence indicates their active participation in and reaction to amyloid and tau pathology.

DOPA Decarboxylase (DDC) has been proposed as a cerebrospinal fluid (CSF) biomarker with increased concentrations in Lewy body disorders (LBDs) and highest levels in patients receiving dopaminergic treatment. Here we evaluate plasma DDC, measured by proximity extension assay, and the effect of dopaminergic treatment in three independent LBD (with a focus on dementia with Lewy bodies (DLB) and Parkinson's disease (PD)) cohorts: an autopsy-confirmed cohort (n = 71), a large multicenter, cross-dementia cohort (n = 1498) and a longitudinal cohort with detailed treatment information (n = 66, median follow-up time[IQR] = 4[4, 4] years). Plasma DDC was not altered between different LBDs and other disease groups or controls in absence of treatment.

Alzheimer's disease (AD) is a common neurodegenerative disease characterized by progressive memory loss and cognitive decline. The processes underlying the pathophysiology of AD are still not fully understood despite a great deal of research. Since mitochondrial dysfunction affects cellular energy metabolism, oxidative stress, and neuronal survival, it is becoming increasingly clear that it plays a major role in the development of AD.
