Summary
Resveratrol, a plant compound, may combat ageing and neurodegenerative diseases by activating the longevity gene SirT1. This review explores resveratrol
Area of Science:
- Gerontology and Neuroscience
- Pharmacology and Therapeutics
Background:
- Aging is a natural process characterized by accumulated cellular damage and metabolic byproducts.
- Neurodegenerative diseases, including Alzheimer's and Parkinson's, pose significant challenges due to their irreversible nature and lack of effective treatments.
- The search for anti-aging interventions and treatments for age-related diseases is a critical area of research.
Purpose of the Study:
- To review the pathogenesis of major age-related neurodegenerative diseases.
- To explore the therapeutic potential of resveratrol, a plant polyphenol, in mitigating aging and neurodegeneration.
- To discuss the roles of diet and stem cell therapy in managing aging and associated diseases.
Main Methods:
- Literature review of studies on aging, neurodegeneration, and resveratrol.
- Analysis of the molecular mechanisms underlying resveratrol's beneficial effects, including SirT1 activation.
- Synthesis of information on the therapeutic strategies for age-related neurodegenerative conditions.
Main Results:
- Resveratrol (3,5,4'-trihydroxystilbene) has demonstrated lifespan-extending properties and protective effects against age-related diseases in various species.
- The anti-aging and therapeutic benefits of resveratrol are linked to the activation of the longevity gene, SirT1.
- Neurodegenerative diseases like Alzheimer's, Parkinson's, and cerebrovascular disease share common pathways influenced by aging.
Conclusions:
- Resveratrol shows significant promise as an anti-aging agent and a potential therapeutic compound for neurodegenerative diseases.
- Dietary interventions and stem cell therapy are also discussed as complementary approaches to address aging and its associated health burdens.
- Further research into the mechanisms and applications of resveratrol, diet, and stem cells is crucial for understanding and managing the aging process.

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...
01:26Aging
Aging is a complex biological phenomenon influenced by various processes that affect cellular and systemic functions. Several prominent theories attempt to explain its mechanisms, highlighting cellular limitations, oxidative damage, and hormonal changes as central factors in aging.
Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...

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...
01:26Alzheimer'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...

01:22Dementia l: Introduction
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
01:19The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
