Introduction: The process of aging is essentially defined by a decline in various physical and mental processes that take place within the human body. Healthy aging is not only accompanied by a decline in cognitive processing, but also motor function, in particular an increase in the slowness of movements and a loss of coordination. Functional brain imaging has indicated that age-related change...

Basic principles of the neurobiology of aging were reviewed within selected topic areas chosen for their potential relevance to epileptogenesis in the aging brain. The availability of National Institute on Aging-supported aged mouse and rat strains and other biological resources for studies of aging and age-associated diseases was presented, and general principles of animal use in gerontologica...

The increased risk for neurodegenerative and neuropsychiatric disorders associated with extended lifespan has long suggested mechanistic links between chronological age and brain-related disorders, including depression, Recent characterizations of age-dependent gene expression changes now show that aging of the human brain engages a specific set of biological pathways along a continuous lifelon...

Aging is the biggest risk factor for idiopathic Alzheimer's disease (AD). Recently, the National Institutes of Health released AD research recommendations that include: appreciating normal brain aging, expanding data-driven research, using open-access resources, and evaluating experimental reproducibility. Transcriptome data sets for aging and AD in humans and animal models are available in NIH...

Objective(s): Ceftriaxone (Cef), a beta-lactam antibiotic, is accompanied by antioxidant and anti-inflammatory properties. It has been shown that Cef has beneficial effects on Alzheimer’s disease. In the current investigation, the effect of Cef in a mice model of aging was investigated. Materials and Methods: Forty male mice were equally...

Introduction: Several reports show a relationship between health equity, and health status and longevity of individuals. In this study, effects of food deprivation, inequality and social instability were investigated on the formation of lipofuscin pigment in Balb/C mice by histopathological and biochemical methods. Methods: Thirty-six male mice were divided into 6 groups, then different kind...

Gene expression studies suggest that aging of the human brain is determined by a complex interplay of molecular events, although both its region- and cell-type-specific consequences remain poorly understood. Here, we extensively characterized aging-altered gene expression changes across ten human brain regions from 480 individuals ranging in age from 16 to 106 years. We show that astrocyte- and...

Remarkable and continued growth in the field of brain aging research has been fueled by a confluence of factors. Developments in molecular biology, imaging, and genetics coupled with the imperative caused by the aging of the population has created fertile ground for improved understanding of the interaction between brain function and behavior. Aging changes in neurochemical systems may account ...

The number of the elderly across the globe will approximate 2.1 billion by 2050. Juxtaposed against this burgeoning segment of the population is evidence that nonpathological aging is associated with an increased risk for cognitive decline in a variety of domains, changes that can cause mild disability even before the onset of dementia. Given that pharmacological treatments that mitigate dement...

Aging is a complex process that differentially impacts multiple cognitive, sensory, neuronal and molecular processes. Technological innovations now allow for parallel investigation of circuit function, structure composition in the brain awake behaving adult mice. Thus, mice have become critical tool to better understand how aging brain. However, more granular systems-based approach, which consi...
