Will Alzheimer be helped by Mitochondrial Biogenesis

This briefing document summarizes the key themes and findings presented in the provided review article on Alzheimer's disease (AD). The article, published in the European Journal of Neurology in 2018, offers a comprehensive overview of AD, including its epidemiology, genetics, pathogenesis, pathology, clinical presentation, diagnosis, and treatment strategies, while also looking ahead to future research directions.
Key Facts and Ideas:
Global Health Concern: Alzheimer's disease is a growing global health concern with "huge implications for individuals and society." (p. 59) It is the "most common cause of dementia," which is defined as "acquired progressive cognitive impairment sufficient to impact on activities of daily living." (p. 59) Current estimates suggest that "44 million people live with dementia worldwide at present." (p. 59)
Increasing Prevalence and Cost: The prevalence of dementia is expected to rise significantly in coming years, particularly in Western countries where it is the single biggest cause of disability. The estimated cost of dementia in the US alone "may exceed US$600 billion [2]." (p. 59)
Epidemiology and Risk Factors: While the exact causes are complex, AD is influenced by a combination of genetic and environmental factors. "Typical' late onset AD is likely to be driven by a complex interplay between genetic and environmental factors." (p. 59) "Epidemiological evidence suggests education and physical exercise may protect against AD, whereas mid-life hypertension and diabetes adversely influence risk [1]." (p. 60)
Genetics: Genetic factors play a significant role in AD, particularly in the less common early-onset familial forms. "Whilst the vast majority of AD occurs on an apparently sporadic basis, mutations in three genes – amyloid precursor protein (APP), presenilin 1 (PSEN1) and presenilin 2 (PSEN2) – cause a rare (<0.5%) familial form of AD (FAD)." (p. 59) The APOE gene is identified as a "single biggest genetic risk for sporadic AD." (p. 59)
Pathology: The hallmark pathological features of AD are the accumulation of amyloid plaques and neurofibrillary tangles in the brain. "The cardinal features of Alzheimer pathology are amyloid plaques and neurofibrillary tangles (NFTs)." (p. 60) Amyloid plaques are composed of aggregates of the β-amyloid (Aβ) peptide, while neurofibrillary tangles are composed of hyperphosphorylated tau protein. Other pathological processes include "neuronal loss and synaptic dysfunction." (p. 60)
Pathogenesis (Amyloid Hypothesis): The article discusses the prevailing "amyloid hypothesis," which proposes that the accumulation and oligomerization of Aβ is a primary driver of the disease process, leading to synaptic dysfunction, tau pathology, and neuronal death. "The amyloid hypothesis, the prevalent theory of AD pathogenesis, suggests that accumulation of pathological forms of Aβ produced by sequential cleavage of the APP by the β- and γ-secretases initiates the primary pathological process, driving through an imbalance between Aβ production and Aβ clearance." (p. 61)
Clinical Features: The most common presentation of AD is with "insidious progressive problems centered on episodic memory." (p. 63) As the disease progresses, individuals experience difficulties with "multi-tasking and loss of condition." (p. 63) Behavioral changes, including depression and apathy, are also common.
Diagnostic Approach: The diagnosis of AD is primarily clinical, based on a detailed history and neurological examination. Cognitive assessments are crucial. While the definitive diagnosis still relies on neuropathological examination post-mortem, "recent diagnostic criteria from both the National Institute on Aging (NIA) and the International Working Group (IWG-2) now incorporate early (amyloid) and late (tau) biomarkers to improve diagnostic sensitivity and specificity." (p. 63) Neuroimaging (MRI and PET) and CSF analysis play an increasing role in supporting the diagnosis and identifying biomarkers.
Biomarkers: Biomarkers, including those measured in CSF (Aβ and tau) and through PET imaging (amyloid and tau), are becoming increasingly important for earlier and more accurate diagnosis, particularly in the preclinical and prodromal stages. "Tau PET imaging, using tracers such as AV1451, is a recent development which is currently only used for research purposes [57]." (p. 64)
Differential Diagnosis: It is important to differentiate AD from other causes of dementia and cognitive impairment, such as vascular dementia, Lewy body dementia, and frontotemporal dementia.
Treatment and Management: Current treatments for AD are primarily symptomatic and aim to manage cognitive and behavioral symptoms. "Disease-modifying treatments, i.e. those proven to alter the underlying disease pathology or disease course, are not yet available." (p. 64) Acetylcholinesterase inhibitors (AChEIs) and memantine are the mainstay of symptomatic treatment. Non-pharmacological approaches, including cognitive stimulation and exercise, are also important components of management.
Future Prospects: Future research is focused on developing disease-modifying therapies that target the underlying pathology, such as amyloid and tau. This includes "antibody-based approaches to amyloid clearance [67]." (p. 67) There is a strong emphasis on identifying individuals at risk and intervening earlier in the disease process, including in the preclinical stage. "The identification of novel drug targets are already leading to the identification of novel drug targets." (p. 67) Personalized medicine approaches, utilizing genetic and biomarker information, are also seen as a key future direction.
Conclusion
The review article highlights the significant progress made in understanding Alzheimer's disease, particularly regarding its genetic and pathological basis. However, it also underscores the urgent need for effective disease-modifying treatments and improved diagnostic tools, especially for early and accurate identification of individuals at risk. The future of AD research lies in a deeper understanding of the complex interplay of factors contributing to the disease, the development of targeted therapies, and the implementation of strategies for early intervention and personalized medicine.

2024 Stats on CVD & Impact of Nutrition (especially Mediterranean Diet)

In this episode, we will review first the stats linked to CVD & strokes and how these ailments impact your lives. Moreover, as an expert in nutrition, we will cover how key nutrition compounds might change your health for the better.
What are the major cardiovascular diseases and their impact in the United States?
Cardiovascular disease (CVD) encompasses a range of conditions, including heart disease and stroke. In 2021, CVD was the underlying cause of death for over 931,000 people in the United States, claiming more lives than all forms of cancer and chronic lower respiratory disease combined. Nearly half of US adults (48.6%) had some form of CVD between 2017 and 2020. The economic burden is substantial, with direct and indirect costs totaling over $422 billion between 2019 and 2020.
What are some key statistics regarding coronary heart disease (CHD) and stroke in the US?
In 2021, coronary heart disease was the leading cause of CVD deaths, accounting for 40.3% of these fatalities. On average, someone in the United States experiences a heart attack approximately every 40 seconds. Stroke was responsible for 17.5% of CVD deaths in 2021, with someone dying from a stroke every 3 minutes and 14 seconds on average. While the death rate attributable to CHD declined by 15.0% between 2011 and 2021, the actual number of deaths remained relatively stable. Conversely, the age-adjusted stroke death rate increased by 8.4% and the actual number of stroke deaths rose by 26.3% during the same period.
How does the American Heart Association (AHA) contribute to addressing cardiovascular diseases?
The American Heart Association is a significant non-profit, non-governmental funder of cardiovascular and cerebrovascular research in the United States. They utilize donations to support research projects, with applications reviewed by volunteer scientists and healthcare professionals. The AHA has funded over $5 billion in research since 1949, and their supported research has contributed to 10 Nobel Prizes.
What are the key risk factors for heart disease and stroke, as identified by the AHA?
The AHA tracks eight key health factors and behaviors, known as "Life's Essential 8," that increase the risk for heart disease and stroke. These include not smoking, physical activity, a healthy diet, maintaining a healthy body weight, getting sufficient sleep, and controlling cholesterol, blood pressure, and blood sugar levels.
What are some statistics related to these risk factors in the US?
Smoking remains a major risk factor, contributing to a significant number of deaths globally and in the US, including from secondhand smoke exposure. Physical inactivity is prevalent, with only 24.2% of US adults meeting aerobic activity guidelines in 2020. Diet scores using the AHA's metric are generally low across demographic groups. Overweight and obesity affect a large proportion of US adults (41.8% prevalence between 2017 and 2020). High cholesterol, insufficient sleep, diabetes (diagnosed and undiagnosed), and high blood pressure are also common issues among US adults.
What does "eating the rainbow" mean in the context of healthy eating?
"Eating the rainbow" is a healthy eating tip that encourages consuming a wide variety of colorful fruits and vegetables. The different colors in produce are due to specific phytonutrients, which are natural compounds that offer protective benefits to plants and may help prevent lifestyle diseases and support overall health in humans. Eating a diverse range of colors ensures intake of a broad spectrum of these beneficial nutrients, which are more powerful for health when obtained from whole foods rather than supplements.
What are some examples of beneficial phytonutrients found in different colored fruits and vegetables and their potential health benefits?
Red foods contain phytochemicals like lycopene and ellagic acid, linked to reduced risk of certain cancers (like prostate and esophageal) and heart disease. Yellow and orange foods are rich in vitamin C and carotenoids (like beta-carotene, lutein, and zeaxanthin), important for immune function, vision health (protecting against cataracts and macular degeneration), and reducing stroke risk. Green vegetables provide lutein, isothiocyanates, isoflavones, folate, and vitamin K, supporting immune function, detoxification, energy levels, cognitive health, and bone health. Purple and blue foods are high in anthocyanins and resveratrol, associated with reduced risk of cancer and heart disease, cognitive support, decreased inflammation, and improved skin health. White and brown produce, such as cauliflower, garlic, onions, and mushrooms, contain compounds like sulforaphane, allicin, quercetin, and phytonutrients that may protect against certain cancers and support bone and heart health.
What are the potential health benefits associated with following a Mediterranean diet?
Research suggests that adhering to a Mediterranean diet, which emphasizes whole, nutrient-dense foods like fruits, vegetables, whole grains, legumes, healthy fats, and lean proteins, can offer numerous health advantages. These include improved sleep quality, reduced inflammation (potentially protecting against conditions like heart disease and COVID-19), increased lifespan, a lower risk of heart disease (particularly in women), reduced dementia risk, lower odds of developing prostate cancer, potential benefits for vision as you age (reducing the risk of progressing from early to late age-related macular degeneration), and a boost to mental health, including reduced stress and improved mood.

Review of Magnesium's Role in Health and Disease
Sources Reviewed:
"Dietary magnesium intake and the risk of cardiovascular disease, type 2 diabetes, and all-cause mortality: a dose–response meta-analysis of prospective cohort studies" (Fang et al., 2016)
"Magnesium" - Linus Pauling Institute Micronutrient Information Center
"Magnesium, Oxidative Stress, Inflammation, and Cardiovascular Disease" (Volpe, 2020)
"The Integral Role of Magnesium in Muscle Integrity & Aging" (Rueda-Ruzafa et al., 2023)
Summary:
These sources collectively highlight the crucial role of magnesium in numerous physiological processes and its association with various health outcomes. Magnesium acts as a cofactor for hundreds of enzymes involved in energy production, DNA synthesis, muscle contraction, nerve function, and blood glucose control. Evidence suggests that both dietary intake and supplementation of magnesium may have protective effects against cardiovascular disease (specifically heart failure and stroke), type 2 diabetes, and all-cause mortality. Magnesium deficiency is linked to increased oxidative stress, inflammation, and metabolic derangements, which contribute to the pathogenesis of chronic diseases. While assessing magnesium status can be challenging, maintaining adequate intake through diet and considering supplementation under medical guidance are important for overall health, particularly in the context of aging and chronic disease prevention and management.
Conclusion:
Magnesium is a critical nutrient with far-reaching effects on human health. The reviewed sources provide compelling evidence for the association between adequate magnesium intake and a reduced risk of several chronic diseases, particularly cardiovascular disease and type 2 diabetes. Magnesium's involvement in fundamental cellular processes, its role in mitigating oxidative stress and inflammation, and its importance for muscle health underscore the need for maintaining sufficient magnesium levels throughout the lifespan. While dietary strategies should be the primary approach, magnesium supplementation may be a valuable adjunct in specific situations under medical guidance. Further research is warranted to fully elucidate the optimal levels of magnesium intake and the therapeutic potential of magnesium supplementation for various health conditions.
