Blood-Brain Barrier Breach Blamed For Brain-Fog

Move Over, Leaky Gut. Now It’s A Leaky Brain.

…which is not a headline that promises good news, and indeed, the only good news about this currently is “now we know another thing that’s happening, and thus can work towards a treatment for it”.

Back in February (most popular media outlets did not rush to publish this, as it rather goes against the narrative of “remember when COVID was a thing?” as though the numbers haven’t risen since the state of emergency was declared over), a team of Irish researchers made a discovery:

❝For the first time, we have been able to show that leaky blood vessels in the human brain, in tandem with a hyperactive immune system may be the key drivers of brain fog associated with long covid❞

~ Dr. Matthew Campbell (one of the researchers)

Let’s break that down a little, borrowing some context from the paper itself:

  • the leaky blood vessels are breaching the blood-brain-barrier
    • that’s a big deal, because that barrier is our only filter between our brain and Things That Definitely Should Not Go In The Brain™
  • a hyperactive immune system can also be described as chronic inflammation
    • in this case, that includes chronic neuroinflammation which, yes, is also a major driver of dementia

You may be wondering what COVID has to do with this, and well:

  • these blood-brain-barrier breaches were very significantly associated (in lay terms: correlated, but correlated is only really used as an absolute in write-ups) with either acute COVID infection, or Long Covid.
  • checking this in vitro, exposure of brain endothelial cells to serum from patients with Long Covid induced the same expression of inflammatory markers.

How important is this?

As another researcher (not to mention: professor of neurology and head of the school of medicine at Trinity) put it:

❝The findings will now likely change the landscape of how we understand and treat post-viral neurological conditions.

It also confirms that the neurological symptoms of long covid are measurable with real and demonstrable metabolic and vascular changes in the brain.❞

~ Dr. Colin Doherty (see mini-bio above)

Want to stay safe?

Beyond the obvious “get protected when offered boosters/updates” (see also: The Truth About Vaccines), other good practices include the same things most people were doing when the pandemic was big news, especially avoiding enclosed densely-populated places, washing hands frequently, and looking after your immune system.

  • Live Life in Crescendo – by Stephen Covey and Cynthia Covey-Haller

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Stephen Covey is of course best known for his “7 Habits of Highly Effective People“, while the dozen books he wrote afterwards, not including this one, did not get the same acclaim.

    Not including this one, because this one was published posthumously and, notwithstanding the order of the names on the cover, in all likelihood his daughter wrote most of.

    And yet! The very spirit of this book is in defiance of 7 Habits being his “early career” magnum opus. We say “early career”, because he was 57 already when that was published, but it was one of his earlier books.

    In this work the authors lay out the case for how “your most important work is always ahead of you“, and that it is perfectly possible to “live life in crescendo“, and keep on giving whatever it is that we want to give to the world.

    We also learn, mostly through storytelling, of how people are infinitely more important than things, and that it is there that we should put our investments. And that while adversity may not make us stronger, it just means we may need to change our approach, to continue to be productive in whatever way is meaningful to us.

    Bottom line: if ever you wonder how your future could live up to your past (in a good way), this is the book to get you thinking.

  • Potatoes & Anxiety

    ❝My other half considers potatoes a wonder food, except when fried. I don’t. I find, when I am eating potatoes I put on weight; and, when I’m not eating them, I lose it. Also, although I can’t swear to it, potatoes also make me feel a little anxious (someone once told me it could have something to do with where they are on the “glycemic index”). What does the science say?❞

    The glycemic index of potatoes depends on the kind of potato (obviously) and also, less obviously, how it’s prepared. For a given white potato, boiling (which removes a lot of starch) might produce a GI of around 60, while instant mash (basically: potato starch) can be more like 80. For reference, pure glucose is 100. And you probably wouldn’t take that in the same quantity you’d take potato, and expect to feel good!

    So: as for anxiety, it could be, since spiked blood sugars can cause mood swings, including anxiety.

    Outside of the matter of blood sugars, the only reference we could find for potatoes causing anxiety was fried potatoes specifically:

    ❝frequent fried food consumption, especially fried potato consumption, is strongly associated with 12% and 7% higher risk of anxiety and depression, respectively❞

    Source: High fried food consumption impacts anxiety and depression due to lipid metabolism disturbance and neuroinflammation

    …which heavily puts the blame not on the potatoes themselves, but on acrylamide (the orange/brown stuff that is made by the Maillard reaction of cooking starches in the absence of water, e.g. by frying, roasting, etc).

    Here’s a very good overview of that, by the way:

  • Saffron For The Brain (& More)

    Saffron For The Brain (& More)

    In yesterday’s edition of 10almonds, one of the items in the “health news from around the world” section was:

    Clinical trial finds herbal medicine Sailuotong effective for brain health in older people

    But, what is it?

    ❝SaiLuoTong (SLT) is a modern compound Chinese herbal medicine preparation in capsule form containing standardized extracts of Panax ginseng, Ginkgo biloba, and Crocus sativus L❞

    Source: A randomized, double-blind, placebo-controlled, parallel-group 12-week pilot phase II trial of SaiLuoTong (SLT) for cognitive function in older adults with mild cognitive impairment

    We’ve written previously about ginseng and ginkgo biloba:

    So, what’s this about Crocus sativus L.?

    That is the plant better known as saffron. And, for all its wide availability (your local supermarket probably has at least a tiny amount in the spice section), there’s a reason we don’t see much of it:

    ❝Saffron blooms only once a year and should be collected within a very short duration. It is picked during 3–4 weeks in October-November. The method for the cultivation of saffron contributes greatly to its high price. According to some reports, this species is a sterile triploid and so does not produce fertile seeds. Germination can take 1–6 months at 18°C. It takes 3 years for plants to flower from seed.❞

    Source: Crocus sativus L.: A comprehensive review

    That’s fascinating, but what does it do for us?

    Well, in the words of El Midaoui et al. (2022):

    ❝In the frame of a double-blind-placebo-controlled study, 30 mg per day supplementation with saffron for 16 weeks resulted in improved cognitive function in patients suffering from mild to moderate Alzheimer’s disease.

    Moreover, the follow-up of this study in which the authors evaluated the effects of saffron (30 mg/day) for 22 weeks showed that saffron was as effective as donepezil in the treatment of mild-to-moderate Alzheimer’s disease❞

    Read the full review: Saffron (Crocus sativus L.): A Source of Nutrients for Health and for the Treatment of Neuropsychiatric and Age-Related Diseases

    Not just that, but it also has powerful antioxidant and anti-inflammatory properties beyond the brain (though the brain is where research has been most focused, due to its neuroprotective effects).

    See: Antioxidant Properties of Crocus Sativus L. and Its Constituents and Relevance to Neurodegenerative Diseases; Focus on Alzheimer’s and Parkinson’s Disease

    (this, too, is a full research review in its own right; we’re getting a lot of “bang for buck” on papers today)

    And more?

    Yes, and more. Lots more. To bullet-pointify even just the abstract from another research review:

    • Saffron has been suggested to be effective in the treatment of a wide range of disorders including coronary artery diseases, hypertension, stomach disorders, dysmenorrhea and learning and memory impairments.
    • In addition, different studies have indicated that saffron has anti-inflammatory, anti-atherosclerotic, antigenotoxic and cytotoxic activities. (This is all good; the cytotoxic activities are about killing cancer cells)
    • Antitussive effects of stigmas and petals of C. sativus and its components, safranal and crocin have also been demonstrated.
    • The anticonvulsant and anti-Alzheimer properties of saffron extract were shown in human and animal studies.
    • The efficacy of C. sativus in the treatment of mild to moderate depression was also reported in clinical trial.
    • Administration of C. sativus and its constituents increased glutamate and dopamine levels in the brain in a dose-dependent manner.
    • It also interacts with the opioid system to reduce withdrawal syndrome.
    • C. sativus and its components can be considered as promising agents in the treatment of nervous system disorders.

    For more details on any of those items, see:

    The effects of Crocus sativus (saffron) and its constituents on nervous system: a review

    Is it safe?

    The effective dose is 30mg/kg and the LD50 is more than 20g/kg, so yes, it’s very safe. Given the price of it, this also means that if you’re the size of this writer (a little over 70kg, or a little over 150lbs) to poison yourself effectively you’d need to consume about 1.4kg of saffron at a time, which would cost well over $6,000.

    Where can I get it?

    Your local supermarket probably has a tiny amount in the spice section, or you can get better prices buying it in “bulk” online. Here’s an example product on Amazon, for your convenience

    ❝As I get older, I seem to be increasingly prone to skin tags, which appear, seemingly out of nowhere, on my face, chest and back. My dermatologist happily burns them off – but is there anything I can do to prevent them?!❞

    Not a lot! But, potentially something.

    The main risk factor for skin tags is genetic, and you can’t change that in any easy way.

    The other main risk factors are connected to each other:

    Skin folds, and chafing

    Skin tags mostly appear where chafing happens. This can be, for example:

    • Inside joint articulations (especially groin and armpits)
    • Between fat rolls (if you have them)

    So, if you have fat rolls, then losing weight will also reduce the risk of skin tags.

    Additionally, obesity and some often-related problems such as diabetes, hypertension, and an atherogenic lipid profile also increase the risk of skin tags (amongst other more serious things):

    See: Association of Skin Tag with Metabolic Syndrome and its Components

    As for the chafing, this can be reduced in various ways, including:

    • losing weight if (and only if) you are carrying excess weight
    • dressing against chafing (consider your underwear choices, for example)
    • keeping hair in the armpits and groin (it’s part of what it’s there for)

    One of the biggest challenges facing anyone learning to cook more healthily, is keeping it tasty. What to cook when your biggest comfort foods all contain things you “should” avoid?

    Happily for us, Dr. Ahmed is here with a focus on comfort food that’s good for your gut health. It’s incidentally equally good for the heart and good against diabetes… but Dr. Ahmed is a gastroenterologist, so that’s where she’s coming from with these.

    There’s a wide range of 101 recipes here, including many tagged vegetarian, vegan, and/or gluten-free, as appropriate.

    While this is not a vegetarian cookbook, Dr. Ahmed does consider the key components of a good diet to be, in order of quantity that should be consumed:

    1. Fruits and vegetables
    2. Whole grains
    3. Legumes
    4. Pulses
    5. Nuts and seeds

    …and as such, the recipes are mostly plant-based.

    The recipes are from all around the world, and/but the ingredients are mostly things that are almost universal. In the event that something might be hard-to-get, she suggests an appropriate substitution.

    The recipes are straightforward and clear, as well as being beautifully illustrated.

    All in all, a fine addition to anyone’s kitchen!

    ❝I recall that Charles Darwin (of Evolution fame) used to spend a day a month in bed in order to maintain his physical and psychological equilibrium. Do you see merit in the idea?❞

    Well, it certainly sounds wonderful! Granted, it may depend on what you do in bed :p

    Descartes did a lot of his work from bed (and also a surprising amount of it while hiding in an oven, but that’s another story), which was probably not so good for the health.

    As for Darwin, his health was terrible in quite a lot of ways, so he may not be a great model.

    However! Certainly taking a break is well-established as an important and healthful practice:

    ❝I don’t like to admit it but I am getting old. Recently, I had my first “fall” (ominous word!) I was walking across some wet decking and, before I knew what had happened, my feet were shooting forwards, and I crashed to the ground. Luckily I wasn’t seriously damaged. But I was wondering whether you can give us some advice about how best to fall. Maybe there are some good videos on the subject? I would like to be able to practice falling so that it doesn’t come as such a shock when it happens!❞
