Summary
Lifestyle medicine interventions like diet and exercise can significantly reduce dementia risk. This review highlights evidence-based strategies for cognitive health and aging well.
Area of Science:
- Gerontology
- Public Health
- Neurology
Background:
- Dementia and cognitive decline represent escalating global health concerns.
- Lifestyle medicine, encompassing diet, exercise, sleep, social connection, stress management, and substance avoidance, offers potential mitigation strategies.
- Traditional research methods like randomized controlled trials (RCTs) have limitations in assessing long-term lifestyle intervention effects.
Purpose of the Study:
- To evaluate the impact of lifestyle factors on dementia and cognitive decline using the HEALM framework.
- To integrate diverse evidence sources for a comprehensive assessment of lifestyle interventions.
- To inform public health strategies for addressing cognitive aging.
Main Methods:
- Development of the Hierarchies of Evidence Applied to Lifestyle Medicine (HEALM) framework by the American College of Lifestyle Medicine (ACLM) and True Health Initiative (THI).
- Utilizing the Evidence Threshold Pathway Mapping (ETPM) approach to inform the HEALM framework.
- Review and synthesis of evidence on lifestyle interventions' effects on cognitive health.
Main Results:
- Strong evidence supports plant-based nutrition, physical activity, restorative sleep, and avoiding risky substances for cognitive health.
- Social connections show potential in mitigating cognitive decline.
- Findings for stress management remain inconclusive, requiring further investigation.
Conclusions:
- Lifestyle interventions are crucial for promoting cognitive health and managing dementia risk.
- Integrating evidence-based lifestyle strategies into public health initiatives can combat the rising dementia burden.
- Continued research is essential to further elucidate the role of lifestyle in cognitive well-being and aging.

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.

01:30Cognitive Development During Adulthood
58
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

01:26Alzheimer's Disease: Overview
448
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...

01:22Alzheimer's Disease: Treatment
165
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
98
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.
