Existing data suggest that Alzheimer's disease is preventable

Area of Science:

• Neuroscience
• Gerontology
• Metabolic Research

Background:

• Alzheimer's disease (AD) is linked to aging, characterized by oxidative stress, metabolic dysfunction, and protein aggregation (amyloid beta, tau).
• Age-related diseases like cardiovascular disease, cancer, and diabetes are influenced by food intake levels.
• Dietary restriction (DR) shows significant benefits in animal models, extending lifespan and reducing disease incidence.

Purpose of the Study:

• To propose dietary restriction (DR) as a preventative strategy for Alzheimer's disease (AD).
• To highlight the potential of DR in mitigating age-related neurodegeneration and promoting successful aging.

Main Methods:

• Review of existing data on dietary restriction (DR) and its effects on aging and age-related diseases.
• Analysis of cellular and molecular changes in AD pathogenesis and their parallels with other aging processes.
• Examination of DR's impact on oxidative stress, energy metabolism, and neuronal resilience.

Main Results:

• DR reduces cellular oxidative stress and improves energy homeostasis.
• DR has demonstrated profound benefits in extending lifespan and reducing age-related diseases in animal studies.
• Emerging evidence suggests DR enhances neuronal resistance to insults relevant to AD pathogenesis.

Conclusions:

• Dietary restriction (DR) presents a promising, widely applicable preventative approach for age-related disorders, including Alzheimer's disease (AD).
• Further research is needed to confirm the extent to which DR can reduce AD incidence in humans.
• Implementing DR may be a prudent strategy for mitigating neurodegenerative disorders and supporting healthy aging.
