    The heart is the engine of our system and the biggest reservoir of mitochondria. If we improve mitochondrial health, we improve heart health. Chronic stress increases heart rate but reduces contractility over time. Reduced contractility results in systemic problems over time - specifically the removal of metabolites from the brain. This is due to the effects of gravity and the location of the subarachnoid space in relation to the heart - although it's the first system to benefit from stress because it initially increases the pressure. But if stress is chronic, over time this leads to reduced heart contractility, even though the heart rate remains high. This reduces vascular pressure and pulsation leading to problems.

    Hypothesis: Alzheimer’s Disease as a Cardiovascular Condition Driven by Heart Contractility and System Coherence
    Alzheimer’s disease (AD) is typically regarded as a neurodegenerative condition characterised by the accumulation of tau proteins and amyloid-beta plaques in the brain. However, I propose that Alzheimer’s may also be understood as a cardiovascular condition, fundamentally driven by heart contractility and the body’s overall system coherence. This hypothesis is based on the role that the heart plays in generating sufficient arterial pressure to push cerebrospinal fluid (CSF) through the brain’s perivascular space (PVS), thereby clearing neurotoxic waste products. The studies attached to this hypothesis-the BALTAZAR study, which explores the effects of caffeine on CSF biomarkers in Alzheimer’s, and the PVS research on CSF flow-are foundational to this argument.
    Key Mechanisms
    1. Heart Contractility and Arterial Pulsations:
    The heart’s contractility is a key driver of arterial pulsatility, which is critical for generating the necessary pressure to push CSF through the glymphatic system in the brain. The PVS study demonstrates that arterial pressure drives CSF flow, which is essential for clearing metabolic waste, including tau and amyloid-beta proteins. Therefore, when heart contractility is weakened, CSF flow diminishes, resulting in the accumulation of waste products that contribute to Alzheimer’s pathology.
    2. Caffeine’s Role in Enhancing Contractility:
    The BALTAZAR study provides evidence that caffeine consumption is associated with improved CSF biomarker profiles in individuals with mild cognitive impairment. Caffeine increases heart contractility and arterial pressure, which, according to the PVS study, would enhance the flow of CSF through the brain. This suggests that caffeine’s protective effects against Alzheimer’s could stem from its ability to maintain or increase heart contractility, facilitating better clearance of neurotoxic proteins from the brain.
    3. System Coherence:
    Heart contractility is not purely a mechanical phenomenon; it is also influenced by the coherence of the mind-body system. In this context, coherence refers to the harmonious functioning of consciousness, the mind, and the body. Consciousness, though separate from the mind and body, can influence their collaboration. When individuals are mentally engaged and consciously aware, heart rate variability (HRV) tends to be high, indicating a coherent system. This coherence can directly enhance heart contractility, thus maintaining effective arterial pressure and CSF flow. Conversely, when coherence is low (due to mental disengagement or stress), heart contractility weakens, exacerbating the risk of neurodegenerative conditions like Alzheimer’s.
    Electromagnetic Considerations
    The heart’s contractility and the body’s overall coherence can be further understood through the lens of electromagnetism. The heart generates a strong electromagnetic field that interacts with the body’s systems, including the brain. In this model:
    - Electricity represents the physical matter of the body.
    - Magnetism represents the energy or mental processes.
    - Electromagnetism represents the conscious coherence that binds the system together.
    Strong heart contractions generate a more coherent and synchronised electromagnetic field, which helps align both mental coherence and physical coherence. If heart contractility is compromised, the body’s electromagnetic field weakens, reducing overall system coherence and potentially accelerating neurodegenerative processes.
    Hypothesis Implications for Alzheimer’s Treatment
    If Alzheimer’s is indeed linked to heart contractility and systemic coherence, future treatments should focus not only on neurological factors but also on improving heart function and enhancing coherence. Such treatments could include:
    1. Pharmacological interventions that improve heart contractility, such as rapamycin (please see attached study) or other cardiovascular agents.
    2. Lifestyle interventions that enhance mental and physical coherence, including meditation, exercise, and heart-rate variability training.
    3. Comprehensive cardiovascular monitoring in Alzheimer’s patients, focusing on contractility and arterial pulsations as key indicators of brain waste clearance efficiency.
    Conclusion
    Alzheimer’s disease should be considered, at least in part, a cardiovascular condition where the failure of heart contractility and system coherence leads to the accumulation of waste products in the brain. By addressing heart health and promoting systemic coherence, we may be able to prevent or slow the progression of Alzheimer’s. The attached research on the PVS system and the effects of caffeine on Alzheimer’s biomarkers provides empirical support for this hypothesis, offering a new lens through which to explore both the causes and treatments of neurodegenerative diseases.

    Hah, you got me to comment.
    What would be the insult that would cause the mitochondria to become a target? I will assume others here have a lot more knowledge than, but I am among those who have tried lots of things and had success, and don't quite know why, but among things I've tried, some I've had to stick to, mostly one thing, and others have faded into the past.
    No seed oils for me, and I have some bias toward the idea that the high omega 6 imbalance, plus any pretense of omega 3 in the form of alpha linolenic acid that converts so slowly to what I have found to be more beneficial DHA/EPA, maybe even DPA... but one element of seed oils I am probably persuaded on, if I am informed correctly, is how the mitochondria isn't very adaptable to metabolizing fats of different saturations. It appears to be somewhat fixed in its electron hand off system, and it can be made to appear at least for a moment that a saturated fat has a predictable chemical formula that runs through cleanly, and as it starts to try generating energy from these polyunsaturated fats, that there are extra and missing hydrogens and oxygens that end up causing it to create more by-products as they produce energy, in the form of free radicals, that then insult the cell.
    If I'm wrong I still can't go back to the seed oils. Avocado, olive, coconut, butter, if there are always trade offs and no elixir of immortality, that is where I am leaning my imbalances for now. My favorite helpful supplements in those days were coenzyme active B vitamins, NAD, alpha lipoic acid, CoQ10, PQQ, all at the end of the day supporting maybe many things, but for my perception of my success in hindsight, metabolic function and clean up. Whatever changed, I still supplement, but not like a junkie, and miss a lot of days. Before if I missed a day I knew and getting the right mix fixed a lot of things. Something changed, and above is my opinion of what it was. If I'm wrong I have still succeeded sufficiently for it to count for me. It is easy for me to imagine mitochondria making more diesel exhaust than clean energy under different situations. If you try it there will be a strange mix of instant relief and nothing at all for 2-5 years. Maybe other microbiome work I did at the time helped in ways I can't as easily tell too. I have not had to maintains any strictness of those protocols and can't quite tell if they helped.

    The microscopy images look weird. I skimmed through the paper and couldn't find the methods part about how they acquired those images/what kind of microscope they used. The DAPI signal looks more than just oversaturated (i.e. more like thresholded and binarized) in 1g, 1i and 31and in 3i I don't quite understand why they used MitoTracker to measure the membrane potential. If I understand that figure correctly they are showing 2D cells, so why didn't they use JC-1 or some other mitochondrial membrane potential dye? I do understand that they wanted to counterstain with TOMM20 (iirc TOMM20 is the name of the gene and TOM20 is the protein btw) but afaik you can't really measure membrane potential using MitoTracker. n=5 for single cells is not great imo and I don't quite understand how they calculate 3j (i.e. how do they determine the fluorescence intensity?). 3k doesn't make any sense whatsoever.
    You need subcellular resolution if you want to determine the mitochondrial membrane potential of individual mitochondria.
    I guess the MitoTracker can tell you which mitochondria are active/don't have a membrane potential, but it's extremely inacurate imo. Just think about incubation time: a short difference in incubation time could make a difference in MitoTracker accumulation. And I think n = 5 are technical replicates (maybe even same well?) and not biological replicates..
    I guess you could say that the ratio of MitoTracker+ & TOM20+ mitochondria / TOM20+ mitochondria can give you an idea of how many active mitochondria you have per cell, but then you need a better resolution to count individual mitochondria, just intensity over the whole cell is a rough estimate.
    The next problem I see is whether 3i is a single slice or stack. And I'd like to see some brightfield images of the cells to see if there are morphological differences.

    If I understand correctly autophagy is critical in this matter, and then one of the best way to induced autophagy is through fasting. Hmm, that means intermittent fasting for example has the potential to repair/replace these mitochondria thus prevent dementia 🤔

    Drugs? Or just do it the natural way through ketosis and/or fasting; promotes mitochondrial biogenesis and autophagy. All our modern diseases are thanks to us being told that we are omnivores, when we are in fact carnivores. A bit like with dogs and cats; they can eat plants/carbs, but just like us, they develop human diseases.

      That makes no sense, Ketosis more than likely induces Senescence, given the body thinks it's in food scarcity mode. Not to mention the long-term effects on Kidney and Heart Function are shown to be overall negative. Fasting might be ok but there's not much data on that so far.
