12 Weeks To Measurably Boost Your Brain

This is Dr. Majid Fotuhi. From humble beginnings (being smuggled out of Iran in 1980 to avoid death in the war), he went on (after teaching himself English, French, and German, hedging his bets as he didn’t know for sure where life would lead him) to get his MD from Harvard Medical School and his PhD in neuroscience from Johns Hopkins University. Since then, he’s had a decades-long illustrious career in neurology and neurophysiology.

What does he want us to know?

The Brain Fitness Program

This is not, by the way, something he’s selling. Rather, it was a landmark 12-week study in which 127 people aged 60–80, of which 63% female, all with a diagnosis of mild cognitive impairment, underwent an interventional trial—in other words, a 12-week brain fitness course.

After it, 84% of the participants showed statistically significant improvements in cognitive function.

Not only that, but of those who underwent MRI testing before and after (not possible for everyone due to practical limitations), 71% showed either no further deterioration of the hippocampus, or actual growth above the baseline volume of the hippocampus (that’s good, and it means functionally the memory center of the brain has been rejuvenated).

You can read a little more about the study here:

A Personalized 12-week “Brain Fitness Program” for Improving Cognitive Function and Increasing the Volume of Hippocampus in Elderly with Mild Cognitive Impairment

As for what the program consisted of, and what Dr. Fotuhi thus recommends for everyone…

Cognitive stimulation

This is critical, so we’re going to spend most time on this one—the others we can give just a quick note and a pointer.

In the study this came in several forms and had the benefit of neurofeedback technology, but he says we can replicate most of the effects by simply doing something cognitively stimulating. Whatever challenges your brain is good, but for maximum effect, it should involve the language faculties of the brain, since these are what tend to get hit most by age-related cognitive decline, and are also what tends to have the biggest impact on life when lost.

If you lose your keys, that’s an inconvenience, but if you can’t communicate what is distressing you, or understand what someone is explaining to you, that’s many times worse—and that kind of thing is a common reality for many people with dementia.

To keep the lights brightly lit in that part of the brain: language-learning is good, at whatever level suits you personally. In other words: there’s a difference between entry-level Duolingo Spanish, and critically analysing Rumi’s poetry in the original Persian, so go with whatever is challenging and/but accessible for you—just like you wouldn’t go to the gym for the first time and try to deadlift 500lbs, but you also probably wouldn’t do curls with the same 1lb weights every day for 10 years.

In other words: progressive overloading is key, for the brain as well as for muscles. Start easy, but if you’re breezing through everything, it’s time to step it up.

If for some reason you’re really set against the idea of learning another language, though, check out:

Mediterranean diet

Shocking nobody, this is once again recommended. You might like to check out the brain-healthy “MIND” tweak to it, here:

Omega-3 supplementation

Nothing complicated here. The brain needs a healthy balance of these fatty acids to function properly, and most people have an incorrect balance (too little omega-3 for the omega-6 present):

What Omega-3 Fatty Acids Really Do For Us ← scroll to “against cognitive decline”

Increasing fitness

There’s a good rule of thumb: what’s healthy for your heart, is healthy for your brain. This is because, like every other organ in your body, the brain does not function well without good circulation bringing plenty of oxygen and nutrients, which means good cardiovascular health is necessary. The brain is extra sensitive to this because it’s a demanding organ in terms of how much stuff it needs delivering via blood, and also because of the (necessary; we’d die quickly and horribly without it) impediment of the blood-brain barrier, and the possibility of beta-amyloid plaques and similar woes (they will build up if circulation isn’t good).

Practising mindfulness medication

This is also straightforward, but not to be underestimated or skipped over:

Lastly…

Dr. Fotuhi wants us to consider looking after our brain the same way we look after our teeth. No, he doesn’t want us to brush our brain, but he does want us to take small measurable actions multiple times per day, every day.

You can’t just spend the day doing nothing but brushing your teeth for the entirety of January the 1st and then expect them to be healthy for the rest of the year; it doesn’t work like that—and it doesn’t work like that for the brain, either.

So, make the habits, and keep them going

Take care!

    Beyond “Make Your Bed”—life lessons from experience

    Beyond “Make Your Bed”—life lessons from experience

    This is Admiral William H. McRaven, a former United States Navy four-star admiral who served as the ninth commander of the United States Special Operations Command.

    So, for those of us whose day-to-day lives don’t involve coordinating military operations, what does he have to offer?

    Quick note: 10almonds’ mission statement is “to make health and productivity crazy simple”.

    We tend to focus on the health side of this, and in the category of productivity, it’s often what most benefits our mental health.

    We’re writing less for career-driven technopreneurs in the 25–35 age bracket and more for people with a more holistic view of productivity and “a good life well-lived”.

    So today’s main feature is more in that vein!

    Start each day with an accomplishment

    McRaven famously gave a speech (and wrote a book) that began with the advice, “make your bed”. The idea here doesn’t have to be literal (if you’ll pardon the pun). Indeed, if you’re partnered, then depending on schedules and habits, it could be you can’t (sensibly) make your bed first thing because your partner is still in it. But! What you can do is start the day with an accomplishment—however small. A short exercise routine is a great example!

    Success in life requires teamwork

    We’re none of us an island (except in the bathtub). The point is… Nobody can do everything alone. Self-sufficiency is an illusion. You can make your own coffee, but could you have made the coffee machine, or even the cup? How about, grown the coffee? Transported it? So don’t be afraid to reach out for (and acknowledge!) help from others. Teamwork really does make the dream work.

    It’s what’s inside that counts

    It’s a common trap to fall into, getting caught up the outside appearance of success, rather than what actually matters the most. We need to remember this when it comes to our own choices, as well as assessing what others might bring to the table!

    A setback is only permanent if you let it be

    No, a positive attitude won’t reverse a lifelong degenerative illness, for example. But what we can do, is take life as comes, and press on with the reality, rather than getting caught up in the “should be”.

    Use failure to your advantage

    Learn. That’s all. Learn, and improve.

    Be daring in life

    To borrow from another military force, the SAS has the motto “Who dares, wins”. Caution has it place, but if we’ve made reasonable preparations*, sometimes being bold is the best (or only!) way forward.

    *Meanwhile the Parachute Regiment, from which come 80% of all SAS soldiers, has the motto “Utrinque paratus”, “prepared on all sides”.

    Keep courage close

    This is about not backing down when we know what’s right and we know what we need to do. Life can be scary! But if we don’t overcome our fears, they can become self-realizing.

    Writer’s note: a good example of this is an advice I sometimes gave during my much more exciting (military) life of some decades ago, and it pertains to getting into a knife-fight (top advice for civilians: don’t).

    But, if you’re in one, you need to not be afraid of getting cut.

    Because if you’re not afraid of getting cut, you will probably get cut.

    But if you are afraid of getting cut, you will definitely get cut.

    Hopefully your life doesn’t involve knives outside of the kitchen (mine doesn’t, these days, and I like it), but the lesson applies to other things too.

    Sometimes the only way out is through.

    Be your best at your worst

    Sometimes life is really, really hard. But if we allow those moments to drive us forwards, they’re also a place we can find more strength than we ever knew we had.

    Keep on swimming

    It’s said that the majority in life is about showing up—and often it is. But you have to keep showing up, day after day. So make what you’re doing sustainable for you, and keep on keeping on.

  • How Useful Are Our Dreams

    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.

    What’s In A Dream?

    We were recently asked:

    ❝I have a question or a suggestion for coverage in your “Psychology Sunday”. Dreams: their relevance, meanings ( if any) interpretations? I just wondered what the modern psychological opinions are about dreams in general.❞

    ~ 10almonds subscriber

    There are two main schools of thought, and one main effort to reconcile those two. The third one hasn’t quite caught on so far as to be considered a “school of thought” yet though.

    The Top-Down Model (Psychoanalysts)

    Psychoanalysts broadly follow the theories of Freud, or at least evolved from there. Freud was demonstrably wrong about very many things. Most of his theories have been debunked and ditched—hence the charitable “or at least evolved from there” phrasing when it comes to modern psychoanalytic schools of thought. Perhaps another day, we’ll go into all the ways Freud went wrong. However, for today, one thing he wasn’t bad at…

    According to Freud, our dreams reveal our subconscious desires and fears, sometimes directly and sometimes dressed in metaphor.

    Examples of literal representations might be:

    • sex dreams (revealing our subconscious desires; perhaps consciously we had not thought about that person that way, or had not considered that sex act desirable)
    • getting killed and dying (revealing our subconscious fear of death, not something most people give a lot of conscious thought to most of the time)

    Examples of metaphorical representations might be:

    • dreams of childhood (revealing our subconscious desires to feel safe and nurtured, or perhaps something else depending on the nature of the dream; maybe a return to innocence, or a clean slate)
    • dreams of being pursued (revealing our subconscious fear of bad consequences of our actions/inactions, for example, responsibilities to which we have not attended, debts are a good example for many people; or social contact where the ball was left in our court and we dropped it, that kind of thing)

    One can read all kinds of guides to dream symbology, and learn such arcane lore as “if you dream of your teeth crumbling, you have financial worries”, but the truth is that “this thing means that other thing” symbolic equations are not only highly personal, but also incredibly culture-bound.

    For example:

    • To one person, bees could be a symbol of feeling plagued by uncountable small threats; to another, they could be a symbol of abundance, or of teamwork
    • One culture’s “crow as an omen of death” is another culture’s “crow as a symbol of wisdom”
      • For that matter, in some cultures, white means purity; in others, it means death.

    Even such classically Freudian things as dreaming of one’s mother and/or father (in whatever context) will be strongly informed by one’s own waking-world relationship (or lack thereof) with same. Even in Freud’s own psychoanalysis, the “mother” for the sake of such analysis was the person who nurtured, and the “father” was the person who drew the nurturer’s attention away, so they could be switched gender roles, or even different people entirely than one’s parents.

    The only real way to know what, if anything, your dreams are trying to tell you, is to ask yourself. You can do that…

    The idea with lucid dreaming is that since any dream character is a facet of your subconscious generated by your own mind, by talking to that character you can ask questions directly of your subconscious (the popular 2010 movie “Inception” was actually quite accurate in this regard, by the way).

    To read more about how to do this kind of self-therapy through lucid dreaming, you might want to check out this book we reviewed previously; it is the go-to book of lucid dreaming enthusiasts, and will honestly give you everything you need in one go:

    Lucid Dreaming: A Concise Guide to Awakening in Your Dreams and in Your Life – by Dr. Stephen LaBerge

    The Bottom-Up Model (Neuroscientists)

    This will take a lot less writing, because it’s practically a null hypothesis (i.e., the simplest default assumption before considering any additional evidence that might support or refute it; usually some variant of “nothing unusual going on here”).

    The Bottom-Up model holds that our brains run regular maintenance cycles during REM sleep (a biological equivalent of defragging a computer), and the brain interprets these pieces of information flying by and, because of the mind’s tendency to look for patterns, fills in the rest (much like how modern generative AI can “expand” a source image to create more of the same and fill in the blanks), resulting in the often narratively wacky, but ultimately random, vivid hallucinations that we call dreams.

    The Hybrid Model (per Cartwright, 2012)

    This is really just one woman’s vision, but it’s an incredibly compelling one, that takes the Bottom-Up model and asks “what if we did all that bio-stuff, and then our subconscious mind influenced the interpretation of the random patterns, to create dreams that are subjectively meaningful, and thus do indeed represent our subconscious?

    It’s best explained in her own words, though, so it’s time for another book recommendation (we’ve reviewed this one before, too):

  • Air Purifiers & Sleep

    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.

    It’s Q&A Day at 10almonds!

    Have a question or a request? We love to hear from you!

    In cases where we’ve already covered something, we might link to what we wrote before, but will always be happy to revisit any of our topics again in the future too—there’s always more to say!

    As ever: if the question/request can be answered briefly, we’ll do it here in our Q&A Thursday edition. If not, we’ll make a main feature of it shortly afterwards!

    So, no question/request too big or small

    ❝I’ve read that air pollution has a negative effect on sleep quality and duration. Since I live next to a busy road, I was wondering whether I should invest in an air purifier. What are 10Almonds’s views?❞

    Going straight to the science, there are two questions here:

    • Does air pollution negatively affect sleep quality and duration?
    • Does the use of an air purify actually improve the air quality in the way(s) necessary to make a difference?

    We thought we’d have to tackle these questions separately, but we did find one study that addressed your question directly. It was a small study (n=30 if you believe the abstract; n=29 if you read the paper itself—one person dropped out); the results were modest but clear:

    ❝The purifier filter was associated with increased total sleep time for an average of 12 min per night, and increased total time in bed for an average of 19 min per night relative to the placebo.

    There were several sleep and mood outcomes for which no changes were observed, and time awake after sleep onset was higher for the purifier filter. Air quality was better during the high-efficiency particulate air filter condition.

    These findings offer positive indications that environmental interventions that improve air quality can have benefits for sleep outcomes in healthy populations who are not exhibiting clinical sleep disturbances.❞

    Source: Can air purification improve sleep quality? A 2-week randomised-controlled crossover pilot study in healthy adults

    In the above-linked paper’s introduction, it does establish the deleterious effect of air pollution on a wide variety of health metrics, including sleep, this latter evidenced per Caddick et al. (2018): A review of the environmental parameters necessary for an optimal sleep environment

    Now, you may be wondering: is an extra 12 minutes per night worth it?

    That’s your choice to make, but we would argue that it is. We can make many choices in our lives that affect our health slightly for the better or the worse. If we make a stack of choices in a particular direction, the effects will also stack, if not outright compound.

    So in the case of sleep, it might be (arbitrary numbers for the sake of illustration):

    • Get good exercise earlier in the day (+3%)
    • Get good food earlier in the day (+2.5%)
    • Practice mindfulness/meditation before bed (+2.5%)
    • Have a nice dark room (+5%)
    • Have fresh bedding (+2.5%)
    • Have an air purifier running (+3%)

    Now, those numbers are, as we said, arbitrary*, but remember that percentages don’t add up; they compound. So that “+3%” starts being a lot more meaningful than if it were just by itself.

    Don’t have an air purifier and want one?

    We don’t sell them, but here’s an example on Amazon, for your convenience

    *Confession: the figure of 3% for the air purifier wasn’t entirely arbitrary; it was based on 100(12/405) = 80/27 ≈ 3, wherein the 405 figure was an approximation of the average total time (in minutes) spent sleeping with placebo, based on a peep at their results graph. There are several ways the average could be reasonably calculated, but 6h45 (i.e., 405 minutes) was an approximate average of those reasonable approximate averages.

    So, 12 minutes is a 3% improvement on that.

    Take care!

    Good For The Eyes; Good For The Brain

    We’ve written before about omega-3 fatty acids, covering the basics and some lesser-known things:

    What Omega-3 Fatty Acids Really Do For Us

    …and while we discussed its well-established benefits against cognitive decline (which is to be expected, because omega-3 is good against inflammation, and a large part of age-related neurodegeneration is heavily related to neuroinflammation), there’s a part of the brain we didn’t talk about in that article: the eyes.

    We did, however, talk in another article about supplements that benefit the eyes and [the rest of the] brain, and the important links between the two, to the point that an examination of the levels of lutein in the retina can inform clinicians about the levels of lutein in the brain as a whole, and strongly predict Alzheimer’s disease (because Alzheimer’s patients have significantly less lutein), here:

    Brain Food? The Eyes Have It!

    Now, let’s tie these two ideas together

    In a recent (June 2024) meta-analysis of high-quality observational studies from the US and around the world, involving nearly a quarter of a million people over 40 (n=241,151), researchers found that a higher intake of omega-3 is significantly linked to a lower risk of macular degeneration.

    To put it in numbers, the highest intake of omega-3s was associated with an 18% reduced risk of early stage macular degeneration.

    They also looked at a breakdown of what kinds of omega-3, and found that taking a blend DHA and EPA worked best of all, although of people who only took one kind, DHA was the best “single type” option.

    You can read the paper in full, here:

    Association between fatty acid intake and age-related macular degeneration: a meta-analysis

    A word about trans-fatty acids (TFAs)

    It was another feature of the same study that, while looking at fatty acids in general, they also found that higher consumption of trans-fatty acids was associated with a higher risk of advanced age-related macular degeneration.

    Specifically, the highest intake of TFAs was associated with a more than 2x increased risk.

    There are two main dietary sources of trans-fatty acids:

    • Processed foods that were made with TFAs; these have now been banned in a lot of places, but only quite recently, and the ban is on the processing, not the sale, so if you buy processed foods that contain ingredients that were processed before 2021 (not uncommon, given the long life of many processed foods), the chances of them having TFAs is higher.
    • Most animal products. Most notably from mammals and their milk, so beef, pork, lamb, milk, cheese, and yes even yogurt. Poultry and fish technically do also contain TFAs in most cases, but the levels are much lower.

    Back to the omega-3 fatty acids…

    If you’re wondering where to get good quality omega-3, well, we listed some of the best dietary sources in our main omega-3 article (linked at the top of today’s).

    However, if you want to supplement, here’s an example product on Amazon that’s high in DHA and EPA, following the science of what we shared today 😎

  • Get Better Sleep: Beyond “Sleep Hygiene”

    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.

    Better Sleep, Better Life!

    This is Arianna Huffington. Yes, that Huffington, of the Huffington Post. But! She’s also the CEO of Thrive Global, a behavior change tech company with the mission of changing the way we work and live—in particular, by challenging the idea that burnout is the required price of success.

    The power of better sleep

    Sleep is a very important, but most often neglected, part of good health. Here are some of Huffington’s top insights from her tech company Thrive, and as per her “Sleep Revolution” initiative.

    Follow your circadian rhythm

    Are you a night owl or a morning lark? Whichever it is, roll with it, and plan around that if your lifestyle allows for such. While it is possible to change from one to the other, we do have a predisposition towards one or the other, and will generally function best when not fighting it.

    This came about, by the way, because we evolved to have half of us awake in the mornings and half in the evenings, to keep us all safe. Socially we’ve marched onwards from that point in evolutionary history, but our bodies are about a hundred generations behind the times, and that’s just what we have to work with!

    Don’t be afraid (or ashamed!) to take naps

    Naps, done right, can be very good for the health—especially if we had a bad night’s sleep the previous night.

    Thrive found that workers are more productive when they have nap rooms, and (following on a little from the previous point) are allowed to sleep in or work from home.

    See also: How To Nap Like A Pro (No More “Sleep Hangovers”!)

    Make sure you have personal space available in bed

    The correlation between relationship satisfaction and sleeping close to one’s partner has been found to be so high that it’s even proportional: the further away a couple sleeps from each other, the less happy they are. But…

    Partners who got good sleep the previous night, will be more likely to want intimacy on any given night—at a rate of an extra 14% per extra hour of sleep the previous night. So, there’s a trade-off, as having more room in bed tends to result in better sleep. Time to get a bigger bed?

    What gets measured, gets done

    This goes for sleep, too! Not only does dream-journaling in the morning cue your subconscious to prepare to dream well the following night, but also, sleep trackers and sleep monitoring apps go a very long way to improving sleep quality, even if no extra steps are consciously taken to “score better”.

    We’ve previously reviewed some of the most popular sleep apps; you can check out for yourself how they measured up:

    We talked about Dr. Wendy Suzuki’s research in the category of exercise and brain-benefits in our main feature the other day. But she has more to say than we can fit into an article!

    This book chronicles her discoveries, through her work in memory and neuroplasticity, to her discoveries about exercise, and her dive into broader neurology-based mental health. So what does neurology-based mental health look like?

    The answer is: mitigating brain-busters such as stress and anxiety, revitalizing a fatigued brain, boosting creativity, and other such benefits.

    Does she argue that exercise is a cure-all? No, not quite. Sometimes there are other things she’s recommending (such as in her chapter on challenging the neurobiology of the stress response, or her chapter on meditation and the brain).

    The writing style is mostly casual, interspersed with occasional mini-lectures (complete with diagrams and other illustrations), and is very readable and informative throughout.

    Bottom line: if you’d like the more in-depth details of Dr. Suzuki’s work, this book is a very accessible way to get 320 pages of that!
