Aging and Disease
|November 15, 2011
Summary
Brain aging alters metabolism, increasing susceptibility to neurological diseases like Alzheimer's and ischemia. Caloric restriction may offer therapeutic benefits by mitigating these age-related metabolic changes.
Area of Science:
- Neuroscience
- Gerontology
- Metabolic Research
Background:
- Aging nervous system exhibits metabolic changes affecting neuronal and glial function.
- Key age-related alterations include vascular reactivity, substrate transport, oxidative stress, and calcium signaling.
- These metabolic shifts increase vulnerability to age-related brain diseases.
Purpose of the Study:
- To examine metabolic changes during brain aging.
- To understand how these changes influence susceptibility to ischemia and cognitive decline.
- To explore potential treatments, such as caloric restriction.
Main Methods:
- Review of existing literature on brain aging and metabolism.
- Analysis of age-related metabolic alterations in neurons, glia, and vasculature.
- Discussion of primary aging theories (mitochondrial, calcium, oxidative stress).
Main Results:
- Metabolic alterations with aging contribute to increased risk for conditions like cerebral ischemia, cognitive impairment, and Alzheimer's disease.
- Specific changes include impaired vascular function, reduced substrate transport, increased reactive oxygen species, and altered calcium homeostasis.
- These findings align with established theories of brain aging.
Conclusions:
- Age-related metabolic dysregulation significantly impacts brain health and disease susceptibility.
- Caloric restriction emerges as a promising therapeutic strategy to counteract detrimental aging processes.
- Further research into the mechanisms of caloric restriction is warranted for neuroprotection.

01:23Alzheimer Disease ll: Pathophysiology
Alzheimer disease involves structural changes in the brain that begin long before symptoms appear. The most distinctive features are extracellular neuritic plaques and intracellular neurofibrillary tangles.Neuritic plaques form in the cerebral cortex and around blood vessels. These plaques contain a dense core of beta-amyloid (Aβ)—a toxic protein fragment that clumps outside neurons. The core is surrounded by damaged neuronal extensions, as well as reactive astrocytes and microglia. Abnormal...
01:29Alzheimer Disease l: Introduction
Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...
01:19Role of Hippocampus in Memory
The hippocampus, a critical brain structure, plays an essential role in memory processing, particularly in the formation and retrieval of memory. This small, seahorse-shaped region is located within the medial temporal lobe, with one hippocampus in each brain hemisphere. Experimental studies involving lesions in the hippocampi of rats have demonstrated significant impairments in tasks such as object recognition and maze navigation, indicating the hippocampus involvement in both recognition and...
01:03Long-term Depression
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

01:26Alzheimer's Disease: Overview
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ and tau...
