10 Silent Warning Signs You're Going To Get Dementia
"If we really want to start slowing down that rate of degeneration,
we need to understand what causes the degeneration so we can reduce those
factors. That is our lifestyle. These are the things that we can affect; those are the things
that we have influence over. And the earlier that you can catch any of these at the very,
very subtle stages, the more likely that you can do something about it relatively simply.
Hello, Health Champions. Today I want to talk about the 10 earliest signs that you might be
moving in the direction of dementia and why is it so critical that we catch these signs
and symptoms early while they're silent because dementia is not reversible. So
if we wait till we have full-blown dementia, there's not a whole lot we can do about it.
But as we talk our way through these signs and symptoms, the first thing I want you to
know is don't panic because every one of us is going to have some of these signs
and symptoms to some degree. The main thing that we want to get out of this is to start
understanding that the brain controls absolutely everything in your body, and therefore any
imbalance at all is going to be a sign of a brain imbalance and some degree of brain degeneration.
But the key to understand here is that some of these are perfectly normal. For example,
if you're right-handed, you will typically have a little bit stronger left brain and a little bit
weaker right brain. So we all have some imbalances to start with. The key is to understand which ones
are normal and which ones really matter. So once we understand that the brain controls
everything and we can start understanding what these signs and symptoms matter,
now we can catch them very, very early and we can do something to prevent dementia.
So at the very basic level, dementia means that there is neural degeneration, that the brain
cells, the neural tissue, the tissue that sends and processes signals just isn't working as well
as it used to. And one way to think about this is a light bulb, that if you start off with a light
bulb that has 100 watts, you can really brighten a room. But then if there's a dimmer that starts
turning the power down on this light bulb and then we go down to 40 or even 25 or 10 watts,
now that light bulb isn't burning so brightly and we're going to cast some shadows on the room. And
the same thing holds true with dementia, that the brain just isn't working as well as it used to.
So let's just look at it very, very simply. That if we have this much brain function,
if we have this many watts of output from the brain, then we have good brain function. If
the function starts declining, then we have reduced brain function, and at some level
we're going to get down to a level where it's not working well enough and we have
dementia. And then at the bottom of the scale here from side to side we have
time. So this would be the beginning of life and the end of it would be the end of life.
Now the thing to understand though is that from birth up until about 20-25 years old we're pretty
much home free. The growth and development of the brain is just part of a natural growth. But
then from 25 years and onwards, now the brain will decline. We're going to lose brain neurons, we're
going to lose connections, and what's important is that we don't lose things so quickly because the
slope, the rate of degeneration, is the key factor here. So if we had a quick degeneration, now we
might start having some decline. We might have some memory loss, we might lose some coordination,
we might have less quality of life at about halfway into life or even earlier. And then at
about three-quarters or so into life, we would see dementias, different degrees of dementia,
and this is what we see in the general population that are heading for dementia.
So it would be a whole lot better if we slow down the rate of decline here. And now you can see
that the time where we would start getting some decline, maybe some brain fog, maybe some lessened
energy or some other degenerative disease, it would move forward in time several years,
maybe a decade or two. And the time that we would hit dementia would move toward the very,
very end of life. And this is what we typically see in the population,
that the vast majority of people have some degree of dementia toward the very end of their life.
But what if we could reduce that rate of decline even more, the rate of degeneration,
so that we can live out our lives and never hit that level of decline, much less dementia,
so that we could have good function all the way throughout life? And this is not
impossible because there are people who get into their 90s and centenarians even
who have good brain function, are clear and sharp to the very end.
But if we really want to start slowing down that rate of degeneration,
we need to understand what causes the degeneration so we can reduce those
factors. And these causes include things like genetic factors, environmental toxins,
oxidative stress, and chronic inflammation. And then there's also some clinical findings
like protein aggregates, mitochondrial dysfunction, apoptosis, and autoimmunity.
And these last ones here, protein aggregates,
those are the little protein buildups that they find in the brains of Alzheimer's people,
for example. Mitochondrial dysfunction is critical because mitochondria are little mini
organs inside your cells that make most of your energy. So as we have a decline in mitochondria,
we have less energy, so of course then that light bulb would start burning a little dimmer.
Apoptosis is programmed cell death, so all cells are supposed to die. There's a turnover of cells,
but if there's a problem, if there's a dysfunction to the timing of this programmed cell death,
now we can have it happen at the wrong time or too early. And autoimmunity is when your
immune system attacks itself and that, of course, can speed up the degeneration.
But if we look at this big list, then the genetic factors are the most important. But we have
to understand what genetic factors mean because most people think that's just your DNA. When we
talk about genetics, most people talk about the genetics that you get when you are conceived and
that you have unchanged throughout life. But that's just your genetic makeup. What
we're talking about is genetic expression because that's the bigger part of these genetic factors.
And the expression of your DNA comes down to lifestyle, which is in this yellow square here.
So the environmental toxins—these are hundreds of thousands of different chemicals that we can
potentially get exposed to that our ancestors didn't have—that's a huge load on the body,
on your DNA, on your genetic makeup. Then we have oxidative stress, which is,
again, part environmental toxins can cause oxidative stress, but then there are many,
many other factors like smoking and processed foods and sugar can
also increase this oxidative stress. And, of course, chronic inflammation,
which we talk a lot about, which is part of metabolic syndrome and also from autoimmunity.
But then all the rest of the list here that people very often talk about as the causes of dementia,
they are really just secondary. They're the result of the stuff in
yellow here. So the yellow is where we need to focus because that is our lifestyle. These are
the things that we can affect; those are the things that we have influence over.
And I like to talk about the Triad of Health. So your health, you can think of it as a triangle
where you have some chemical factors, you have some structural factors, and you have some
emotional factors. So chemical, those are the nutritional aspects, the quality of the things
that you put in, but also other chemicals that get in the way like toxins, for example. Structure has
to do with posture and movement and exercise and flexibility and so forth, and this is why it's
critical that we maintain some movement, we maintain some physical activity. And emotion,
that is basically how good you feel. That's positive emotions on the upside like joy and
purpose and happiness, and stress or anything that feels bad on the downside. So there's a
positive and a negative aspect to all of these three, and they're like three sides of a table.
And all of these three will affect the environmental toxins,
your level of oxidative stress, your chronic inflammation. That is where that comes from.
And when we add it all up, then this becomes a body burden. This is like the chronic load
that your body has to deal with whenever it's going through your daily life. And
the higher your body burden is, the more the load is on the lifestyle factors,
and the more difficult it is for your body to express those genetic factors favorably.
The first sign would be some kind of change in your special senses like smell, for example. So
if you start having difficulty in distinguishing different smells that you used to be able to,
that could very well be that you're getting a little bit of brain degeneration. You
could also have noticed that things that you do recognize but they're more dull,
they don't have that lively fragrance anymore. And then we have taste, of course,
which is a combination of taste buds and smell. So when your smell starts to decrease,
now the food starts losing some of that interesting flavor also.
Another important special sense is vision when you look at things, but it's not what people
would usually associate with vision. It's not your visual acuity, whether you need glasses
or not. This would have more to do with a lack of depth perception because that has
to do with brain processing. It could have to do with your peripheral vision, as your brain
doesn't have the same capacity to process. Then it starts to focus more right in front of you,
and you lose some of that periphery. And it could also be that you're seeing fairly well,
but that you have a hard time interpreting and making meaning out of what you're seeing.
And the next special sense is hearing, and it is inevitable with increased age
that you're going to be losing some of those high frequencies. You're going to
hear more of the lower frequency band. But even if you hear well, you might
have trouble understanding speech; it doesn't sound as clear and it doesn't
make as much sense anymore. And it could also be that you're not as good at determining the
direction of the sound anymore because all of that, of course, is brain processing.
And the last special sense is touch. And here it could be that you start noticing a reduced
sensitivity to pain, and it could also be that you're losing some of your tactile senses,
the fine touch. And it could also be less sensitive to temperatures.
Now, all the special senses have to do with processing incoming information,
but the next one, number two, has to do with motor function. So now it's the type
of information that the brain sends out, and this has a lot to do with movement. And one thing that
you're probably familiar with is posture. As we get older, then people tend to have a hunched
posture or a stooped posture, but again, this is not inevitable. If we work on our posture,
if we maintain movement and we practice posture, then it doesn't have to become that way.
Another thing you might notice is if your hands turn in because part of a stress response is that
we get in a defense posture. We roll our shoulders in, we pull our shoulders up, the hands turn in,
and it's the brain that's supposed to turn that off. So the better the brain is working,
the quicker we can return to normal and get our arms into a normal posture,
which is where the hands are parallel to the body.
Another important aspect is gait and arm swing. And here you can really kind of get
detailed on looking at this. One thing that often happens is shorter steps,
and then oftentimes when it gets more severe, elderly people start to shuffle. But it could
also be simply asymmetrical, and this is something that you could look for. And it's interesting,
if you look around you, you hardly ever see anyone walk with arm swing that is the same
on both sides. So however much the right and left arm are swinging forward and back,
it should be symmetrical. Whichever side has the lesser arm swing is typically the
weaker side of the brain. But if you just start walking and practicing, now you're reinforcing,
you're reviving these pathways, and you're building up that aspect again.
Another motor function is balance because your brain has to process millions and millions of
pieces of information every second for you to stand still when we only have two
feet to stand on. And this could be that you notice you're a little clumsy maybe or that
you have more frequent falls or maybe that you're just feeling a little bit unsteady.
And closely related to that is coordination, which is your ability to move your body relative
to other objects in space. And this could be something as simple as catching a ball or even
maybe start buttoning a shirt. If those movements start to feel difficult, that could be a sign
of early brain degeneration. And the earlier that you can catch any of these at the very,
very subtle stages, the more likely that you can do something about it relatively simply.
Another aspect of motor function is also facial expressions and
facial asymmetry. So the brain tells all the little muscles what to do,
and the health of the brain sets the basic tone. So if you have more muscle tone on
one side of the face than the other, if you notice, for example, that one side is drooped,
then that can be a sign of degeneration. It could be that you notice that you or someone
else is less expressive, that their face doesn't have as much expression anymore, and maybe you
see that you or someone is developing more of a crooked smile or some other facial expression.
Sign number three is handwriting. So if you used to write really neatly and then
it starts to look more sloppy, then that can be a sign of brain degeneration because you
don't have that same level of control. And, of course, I'll have to mention that doctors are,
of course, exempt from this rule because we are trained to write very, very sloppy. So
what we're talking about is more recent changes; it's not something you've done all your life. But
if you notice that it gets more shaky and less controlled, then that may not be a good thing.
And another very specific case is called micrographia, and this is particularly associated
with Parkinson's disease. And this is where you notice if someone is starting to write very,
very slow and very, very small. It's like they're taking great care to write, but everything becomes
really tiny. And this is for three reasons. With Parkinson's, you have less speed of your motions,
so you have to focus harder on controlling them, and you're also getting more muscle stiffness
because the brain sets the muscle tone, meaning it decides how much to turn it on and off at any
given moment. And with Parkinson's, you get muscle stiffness because it doesn't know how to turn it
off. And, of course, with Parkinson's, you also have less control, less coordinated movements.
Number four is speech changes, and here again we're talking about very subtle changes. That
could be something like just a weaker voice or a softer voice where someone used to be
very expressive and now it pulls back a little bit. It could be slurring of words, it doesn't
sound as clear as it used to, or it could be hesitation as if people are constantly searching
for words. If they stop mid-sentence, it's like they have to plan out what they're doing.
Number five is difficulty swallowing, and this might seem strange to some people,
but swallowing is a pretty complicated thing. A lot of things we take for granted have many,
many different steps to them. And, of course, the brain controls all of this. This would be if you
have difficulty swallowing in the absence of some other noticeable fact, like when you don't have a
sore throat or you don't have a swelling. In some cases where people have a neck problem,
like they have a growth on their spine or they have an enlarged thyroid or something,
that could affect your ability to swallow. But if you have trouble even
when there's nothing that they can find, then that could be a neurological thing.
Number six is tremors, which is a form of mild shaking, repetitive shaking. And this one we
need to understand a little bit because here we're talking about some mild and
temporary shaking initially. And this would be mostly noticed in your hands and fingers,
and it would be at rest, meaning you're just kind of sitting there and it starts
shaking. So this is not like you're doing a hard workout and you've exhausted a muscle,
and then you go reach for something and you shake. That's normal. But if it's mild and
temporary and you're at rest, then that could be a sign that your brain isn't working quite right.
And related to that, I want to mention something called a twitching eyelid or a blepharospasm,
which it's called, and that's where your eyelids start twitching. And it might twitch for a few
minutes or half a day or off and on, but then it goes away. So I wouldn't say that that's normal,
but everyone has had that at some point, and it doesn't mean nothing. It means that
there was an imbalance in your brain and nervous system, but it was temporary. So
we don't want to worry too much about all the little things that come and go.
Number seven is less stamina, and here we're talking about different types. We're talking
about physical endurance because if you're working out, if you're moving physically,
if you're exercising, the brain still has to drive that activity. But then, of course,
if you're sitting still and you're working on something cognitive, something mental,
then that's another type of endurance. But they both go back to the brain; they depend on the
brain. And, of course, one aspect of that would be focus. So if you notice that you don't have the
same endurance in terms of focus and getting things done, then that could also be a sign.
Sign number eight is decreased reflexes, so this could be a slower reaction time in general,
or it could be more specific, like we have slower responses to visual or
auditory cues. Like something shows up in our visual field,
we see or we hear something, and it just takes a little bit longer to react.
Sign number nine is spatial confusion, and this is when you don't have a great sense of direction
anymore. And before you panic, let me just say that I don't feel like I have a great sense of
direction, and it's gotten way, way worse since we got all these automatic navigation devices
in our cars and on our phones that tell us every moment where we're supposed to go. But what we're
talking about here is more of a change, that if there is an area that you're supposed to
know and all of a sudden you have difficulty navigating even though it should be familiar.
And another one could be that you have spatial confusion in an area,
in an environment, in a room that should be very familiar.
And sign number ten is a change in emotional affect, and that's another word for emotional
expression. There are some people who tend to have a very flat affect. That means that they don't
show much emotion with their facial expressions or their voice. So when you have flat affect,
then you have less vocal intonation. So it's normal in speech to have your voice
go up and down. Part of this is culture, part of its habit, part is personality,
but we express emotions by varying our vocal intonation. And as the brain becomes a little
weaker, a little slower, then very often we can lose some of that variation and get more of a
flat affect. So we're not expressing emotions that well or not demonstrating it to others.
And one way we do this is with our voices, and another way
is with facial expression. So if both of those start going a little more flat,
that could be a sign that your brain is not as bright anymore.
So if it's a very early gradual degeneration, we would probably be more likely to see a flat
affect. But in later stages, we could actually see the exact opposite because now the brain is
supposed to inhibit certain spontaneous outbursts. And if the brain isn't strong enough to inhibit,
to control that anymore, now we can see the opposite with exaggerated vocal intonation and
vocal expression and facial expressions, and we can see things like outbursts.
So I hope you see how the brain is really what controls everything. There are no accidents. If
you stumble, if you have sloppy handwriting, if you are out of balance, it all means something.
It's not accident. And if you want to learn how to make things better, how to start addressing these
things at an early stage, then I have lots and lots of videos on this. It's pretty much what we
