Dementia and Alzheimer's Disease: a Multifaceted View
From an early age, I was taught that physical ailments took precedence over any emotional/ mental issues that could be occurring. For example, my parents always took us to our doctor’s appointments whenever we were sick and whenever we needed checkups. If there was a physical symptom present (coughing, runny nose, body aches, etc), it was an immediate onset of questions and concerns. Emotionally, stress was acknowledged and was taken care of by giving space or sustenance to help us cope with it. However, things that couldn’t necessarily be pinpointed were depression, anxiety, ADD/ ADHD, bipolar disorder, etc, which all run prevalently in my family. These were issues that were not in any way degraded: they were simply issues that were presented as “American” beliefs, or things that did not exist when my mom lived in Mexico on her little ranch or when my dad lived in the city a couple of hours away from her. My understanding of the brain was very limited until high school, when I was exposed to several different ideas about how the brain works and how it functions to monitor other parts of the body. The brain was and continues to be a fascinating entity that encompasses all aspects of who we are as people, what biological elements influence our stability, why we think the way we do and how all of these things come together to aid us in staying alive. In an ayurvedic perspective, the brain would be the root that spans into every crack and crevice of the human body. To better comprehend the fullest picture that we possibly can, we have to go past the biological and dive into the social and psychological scopes.
Brain disorders/diseases in particular are typically categorized in 5 different groups. Neurological disorders, storage disorders, personality/ mood disorders, developmental disorders and prion diseases. The classification of these conditions dates back to Ancient Greece, where it is believed that Hippocrates had the first official ranking for mental illnesses, including melancholia, mania and phobias. Since then, the groupings and types of ailments linked to them have changed, and they continue to be updated periodically as more information and data are collected. Neurological disorders include, but are not limited to, Myasthenia, Gravis, Multiple Sclerosis, ALS, AD, Parkinson’s disease, Huntington’s disease and Dementia. These disorders often affect motor function, the psychological and/ or cognitive mind as well as the emotions. Storage disorders include Tay-Sachs or Gaucher. They are considered to be metabolic disorders that result in degradation of certain lysosomal enzymes meant to digest the larger and more harmful molecules inside cells. Personality/ mood disorders are disorders that include the more common ones we typically hear about, such as schizophrenia, paranoia, obsessive compulsive disorder, depression and bipolar disorder. These are mental disorders that are characteristic of unhealthy patterns of thinking, functioning and behaving. Developmental disorders are disorders like autism, spectrum disorders and Prader-Willi. In psychiatry, this category of disorders is defined as appearing in childhood and is characterized by delay in development of one or more psychological functions (i.e. language). Finally, prion diseases include Creutz-feldt-Jakob, otherwise known as spongiform encephalopathy. These diseases are rare, neurodegenerative disorders that can lead to death.
A neurocognitive disorder we will deconstruct is dementia, along with a specific type of it: Alzheimer's disease. Dementia is generally defined as the deterioration of intellectual abilities due to disease. Memory is affected along with judgement and concentration. Dementia also comes with personality changes and emotional instability and can be caused by strokes, diabetes, Huntington’s and Parkinson’s disease, and Korsakoff’s syndrome (severe amnesia). Biologically, there is damage to brain cells in dementia, which interferes with their ability to communicate with one another. As the brain cells get damaged, they become less able to reproduce and multiply to replenish the cells that have already died off. Due to this loss, parts of the brain begin to shrink and more issues begin to arise as a result. The brain as an entity has specific deficits in neurotransmitters like norepinephrine, serotonin, and acetylcholine, that also obstruct its ability to fully function. In psychology, there is a distinction between that scientific aspect, being the brain itself, and the emotional/ cognitive aspect: the mind. The brain is the tangible part, the one that is divided into the forebrain, the midbrain and the hindbrain. The mind is the intangible aspect that has three components to it as well: the conscious, the subconscious and the unconscious. Psychologically, people who have dementia are progressively experiencing changes in function such as memory, language, attention, visual perception, problem solving and concentration. These difficulties affect their sense of identity, how they behave, their mood, their overall well being and alter their social relationships. Once diagnosed, the “people centered” ideal to help individuals with dementia cope with their disorder can either amplify their symptoms or make their condition more manageable. It all depends on their conscious awareness of the disease, how they address their emotional distresses and what support system they have in place to aid them in their stages. The psychological view intertwines with humanism, the social theory that emphasizes common human needs and aims to seek rational ways to solve these human problems. In contrast, the biological view focuses on what can be measured, observed or seen inside the matrix of cells, tissues, organs, etc. Both are needed in order to fully understand the extent of dementia and its components.
A type of dementia we mentioned briefly is Alzheimer’s disease. We don’t know what the exact cause is (as is apparent in most brain disorders) but what we do know is that the risk of developing it is linked with genetics. Some patients with AD have a specific genetic problem that can cause an early onset of it as early as 45 years old. Most patients with AD, however, follow other irregular patterns that make it difficult to spot. In neuroimaging, it has been observed that AD patients have plaques (made up of proteins called beta-amyloid) in parts of the brain that show cell loss. The protein that makes up plaques comes from a protein called Amyloid Precursor Protein, or APP, and is needed for neurons to function normally. APP is unfortunately cut up by enzymes into abnormal amounts of beta amyloid. Neurons can get rid of beta amyloid, but only in small amounts. If there is too much, beta amyloid clumps together to form plaques inside of neurons. As a result, the neurons do not function normally and they die off. In addition to that, patients with AD also have “tangles” in neurons. The term is in relation to microtubules, long string-like structures that transport things from the cell body to the end of the axon and dendrites. Those microtubules break apart and collapse into loose nerve endings (axon terminals) and leave a tangled, dysfunctional and dead mess. Externally and simultaneously, the mind is detaching from the person’s body over time. People with AD start to lose their independence and begin to get lost in the memories they have already lived through. They start to digress. One moment, they may be with their spouse or their child and know they are in the car and who they are with, but the next, there may be a shift in their demeanor and they are suddenly confused with their surroundings, where they're going and who it is they were just speaking to. They need to be cared for in a way that helps them live through what goes in their mind. This shift is difficult for those going through these constant shifts and changes, but it is also hard for those that stand by them through it all.
There are some medications that have been approved by the US Food and Drug Administration to treat different types of dementia. Those medications include Cognex, Aricept, Reminyl, Exelon and Namenda. All of them actively inhibit acetylcholinesterase, aside from Namenda. Acetylcholine is a neurotransmitter that is released from the presynaptic neuron and then reabsorbed within the body. There is a lot of it in the hippocampus and the cortex. The enzyme acetylcholinesterase breaks down acetylcholine. So in inhibiting the enzyme, the brain is able to retain acetylcholine in the synaptic cleft in order to stimulate receptors on neurons in learning and memory areas. A key factor to consider in these inhibitory medications is that there is some improvement in daily living skills and there is some delay in the progression of the disease. However, it is typically to a small degree and occurs in a small percentage of patients. It can also be very toxic to the liver, which can backfire on life’s overall improvement and can worsen a patient’s mentality about their condition. Namenda, which is the medication we excluded prior, blocks the NMDA receptor for a very short period of time. NMDA receptors are hypothesized to contribute to neuron death in Alzheimer’s disease. There have been small effects in a small number of patients but they have had a dramatic impact on their quality of life.
In caring for individuals with dementia or Alzheimer’s disease, it is important to consider the overwhelming costs to treat the disease. According to the multinational biotechnology company Biogen, the direct costs for Alzheimer’s disease and other dementias are estimated at $305 billion for last year alone (Alzheimer’s Association, 2020). Treatment facilities like hospitals, nursing homes, hospice, and home healthcare are also taxed with the burden of having tons of patients but not enough geriatricians, nurse practitioners and other professionals to assist with caring for them. On top of that, an Alzheimer’s Association survey revealed that primary care physicians feel inadequate to manage the rising AD population: 39% of primary care physicians are uncomfortable making a diagnosis for AD, 55% are concerned that there are not enough specialists to meet the demand and 22% had absolutely no dementia training during their residency (after medical school) (AA, 2020).
It is impossible to have an ideal situation when dealing with an inevitable disease. However, looking at the biological component of what is going on, the patient’s well being and emotions along with the well being and emotions of those close to them and the primary care physicians involved in treating the patients, helps lessen the gaps in our own misconceptions or ideas. Everything in the body is connected, but the elements that come into play outside of the body are also tied to it.

Ayurveda and the Brain

Metabolism and Ayurveda
I
found the topic of Ayurveda to be very interesting because it is all about the connectedness of the mind, body, and spirit which I feel like I have heard
about in other contexts throughout my life without using the specific term Ayurveda.
For example, I have an aunt that is very involved in homeopathic treatments. From
what she has explained to me it is all about energies and the balance of those
energies. There are physical or mental stressors that trigger an imbalance of
those energies that she treats with extremely diluted substances that are
supposed to interact with the person’s energy to recenter them. There is not much
scientific evidence backing Ayurveda and homeopathic medical practices, but
nevertheless, my aunt swears by it. Even if it is just a placebo effect it still
shows that there is a relationship between the mind and body that is important
for healing and that they are both important things to consider during medical
treatment.
After researching diabetes, it was interesting to compare
that disease and its effects on the body with the ideas of Ayurveda. Diabetes
shows that if one thing gets thrown off in the body the whole body starts
having other issues since the balance has been thrown off. Since blood sugar
levels are unable to be properly regulated by the systems in place, other
systems try to pick up that slack which leads to issues in seemingly unrelated systems
since they have to do a job they are not designed for. I had previously noticed
that people with diabetes often have other medical conditions they need treatment
for, but I never would have guessed that those conditions could be connected to
diabetes. Diabetes could lead to things like increased inflammation or differences
in the microbiome when compared to someone who does not have diabetes. Even
things like mental health get affected by this disease. In the article “Chronic
Illness and Mental Health: Recognizing and Treating Depression” by the National
Institute of Mental Health, it states that diabetes may increase your risk for
depression, and if the person does get depression, then the symptoms of both
diseases often increase creating an even worse situation for the person. I
think that this is especially a good example of Ayurveda and shows the
connectedness of mind and body since diseases of the body and mind can make each
other’s symptoms worse. I do not fully understand if there is any chemical
evidence for the relationship between the severity of symptoms of diabetes and
depression or if it just more of an example of Ayurveda and the connectedness
of mind and body.
In some of the microbiome content provided, I learned
about the connectedness of the microbiome and the whole body. This is similar
to the fact that diabetes often leads to other complications since a change in
the microbiome may lead to other diseases or complications as well. I believe
this shows just how delicate the balance of the body is and how easy it is to
throw off that balance which can lead to some pretty extreme consequences if
not addressed quickly. I found this information super interesting because your gut
microbiome is linked to your digestive health, which I was aware of, but it is
also linked to things like weight or sleep patterns which I was not previously
aware of. I think that the gut microbiome would be a super interesting thing to
research because if we can take some medication that targets the gut maybe we
can help with the high obesity levels in our society or maybe help people with
insomnia get some good sleep. In the article, “Cancer and The Gut Microbiota:
An Unexpected Link” it describes the relationship between the gut microbiome
and disease. Something may throw off the microbiome which leads to disease but
then trying to treat that disease by changing something in the microbiome may
lead to side effects with the intestinal barrier, so once that balance is
skewed it is hard to correct.
The relationship between the microbiome and cancer was very
intriguing to me since I have just taken microbiology and a lot of that
information is still fresh in my brain. All of the treatments paired with
bacteria sounded very situational and did not seem to have a high or consistent
success rate. For example, in some cases, gram-positive bacteria would help with
cancer treatments, but then in other cases, the gram-positive bacteria would
make treatments less effective. The antibiotic treatments paired with cancer
sounded especially shaky since that would get rid of some harmful bacteria, but
it would also get rid of other good bacteria which disturbs the balance of the
microbiome and may have more negative side effects. Overall, I found it
interesting that something as small as bacteria in our gut can have such a big
impact on the whole body and things like cancer which can be life-threatening.
I was aware the microbiome affected things like IBS but at least that will not kill
you like cancer may.
After doing this research I feel a lot more open-minded and
aware of all parts of the body when it comes to disease. I think that it would
be beneficial to not simply treat symptoms of a disease but try and see the
bigger picture of the illness. Even just making sure the patient is in a good headspace
can make a big difference in treatment. I know sometimes when I think too much,
I give myself a headache and if I just take a minute to breathe and readjust
the headache goes away. There is definitely a strong connection between the mind
and the body when it comes to disease and other physical ailments.
Understanding Metabolism through Ayurveda
Ayurveda is an alternative, medicinal system that has stemmed from tradition and dates back to thousands of years. It first began in India and is deeply rooted with the whole person (body, mind and spirit). When it is regarding disease, it means there is an imbalance with the tridoshas (life energies). The three are Vata dosha (space and air); Pitta dosha (fire and water); and Kapha dosha (water and earth). Your Prakriti, which is the prime material energy of which all matter is composed, can help determine what specific diseases or illnesses you are most prone to. People that are composed of Kapha are more susceptible to tonsillitis or congestion in the lungs as a whole. Being made of Pitta would mean you have other vulnerabilities in the stomach or liver as well as be more inclined to have skin disorders. Vata people have a common origin for disease: the large intestine. It is also believed that a disease that exists within the body can present its symptoms in the mind.
The environmental aspect to this plays a relevant part in the disruption of the tridoshas as well. There are specific emotions that correspond to each one of these and can better help those who practice Ayurveda understand where the problem lies. If there is excess pitta within the body, it will produce anger, hatred and feelings of envy. Pitta is fire and water, so there may be something going on in the stomach, liver or there’s a developing skin disorder not yet perceived. The main idea that is established by ayurveda is connectivity. Everything is made up of matter. Matter is present within us and outside of us. Our bodies are constantly performing functions to help keep us alive and balanced. If there is something wrong with the pancreas, for example, and it does not produce enough insulin to help your body function in normality, you will develop diabetes. In developing this, over time, the body will experience other disruptions. There are multiple pathways, but the idea is the same: there are connections in every part of our body, down to the very cells inside.
This disorder of the pancreas is most commonly referred to as diabetes. According to the CDC (Centers for Disease Control and Prevention), diabetes is a chronic (long-lasting) health condition that affects how your body turns food into energy (2020, para. 1). Most of the food that we ingest breaks down into sugar or glucose and those molecules are then carried through to the rest of our body by our blood. When there is too much sugar for the body to handle, there is a signal that notifies the pancreas to release insulin. Insulin is like the mediator: it helps cells get the energy they need, but also helps regulate the sugar in our system. With diabetes, there may be too much insulin, too little insulin or no insulin at all. There are 2 types: Type 1 and Type 2. Type 1 diabetes mellitus is termed “insulin-dependent” and it is less common than Type 2 diabetes. It is speculated that it can be caused by a hereditary predisposition, endocrine diseases, drugs and chemical toxins, unfavorable environmental factors, damage or removal of the pancreas, autoimmune diseases, viruses and infections or by the autoimmune destruction of beta cells in the pancreas (which are responsible for creating and releasing insulin). As a result of these influences, those that suffer from Type 1 diabetes have an insufficient amount of insulin inside their bodies. As for Type 2 diabetes, this is the most common type for adults. This is also the one that most people have knowledge of. Some causes include a family history of diabetes (genetics), race/ ethnicity, history of gestational diabetes, physical inactivity, high body fat or body weight, high cholesterol, high blood pressure, etc. There is no problem with insulin secretion, but the body becomes insulin resistant over time. Like a lock and key, insulin needs to bind to its receptors in order to allow sugar to go into the cells and provide them energy. Since this isn’t happening, there is an excess amount of sugar in the bloodstream and that leads to hyperglycemia.
Diabetes does not remain in the pancreas: it affects other parts of the body as well. In an ayurvedic perspective, diabetes is an imbalance of kappa dosha that can cause other issues that stem in different places throughout the body. In the eyes, it can cause cataracts, glaucoma or retinopathy, each of which can affect the longevity of your eyes and how well you see throughout time. In the kidneys, diabetes can cause high blood pressure, which can damage blood vessels and overwork the organ. The kidney can then become diseased (nephropathy). Being hyperglycemic (having too much sugar in the blood) can damage nerves in the peripheral nervous system, our “rest and digest” system. As a result, there may be pain and numbness in certain parts of the body, including the feet. Wounds may become infected and lead to gangrene and limbs may need to be amputated to prevent the infection from affecting other limbs.
Among the 15 leading causes of death in 2013, diabetes mellitus ranked number 7, along with cerebrovascular diseases (strokes) at number 4 and essential hypertension and hypertensive renal disease at number 13. All of these diseases are attributed to lack of exercise and insufficient physical activity. Based on what has been previously written and reported by several sources, diabetes affects more than just blood sugar and insulin. Despite having factors like environment (low income, poor living conditions, low educational attainment, etc), and/or a genetic predisposition to diabetes, it is imperative to find ways to mitigate the onset of it. Accepting the “inevitable” is what furthers the issue. Exercise can help and is proven to lower blood pressure. Eating a healthy and balanced diet also assists in promoting good “gut” bacteria that enables the body to digest more quickly and efficiently. All foods have certain benefits when ingested. Similarly, Ayurvedic treatment for diabetes involves using herbal supplements (using plants that have medicinal properties to promote and enhance insulin sensitivity and balance) as well as exercise and weight management.
Ayurveda is a practice but also a concept that is meant to enlighten and enhance medicinal approaches. Everything has energy: specific things may have better energy than others. Good habits like eating healthy, for example, would have good energy, as it can boost metabolism and digestion, help the body feel healthy and balanced, etc. Bad habits like drinking alcohol when your blood sugar is low or eating salty and sugary foods at nighttime are “worse” habits, if you will, and open up doors that lead to other problems. It is worth looking into this idea because it can reveal truths we may not have known or understood before. Life is complicated and the human body is complicated too. There are many things we don’t have knowledge about, and many missing pieces. Combining the structural, ever expanding, logic (Western medicine) with the spiritual, connective and natural (Ayurvedic) might help shed light on how to treat new diseases and how to mitigate the onset of others.

Metabolism and Ayurveda
The Adapting Body
The human body is an amazing machine, and like all machines, they require the correct components for basic function, i.e. glucose for basic
cellular respiration. Unlike machines though, the human body tends to find a
way to work regardless of the lack of correct components, such as through gluconeogenesis.
Our
bodies have very intricate metabolic pathways that allow us to do extraordinary
things. As most people know, glucose is the main fuel source for basic metabolic
function but what happens when there is no more glucose to use. Thankfully, the
body finds a way to make glucose so that it can continue to thrive and grow. It
does this by breaking down glycogen stores first and then it begins to create
new sugars that can be used for cellular respiration. This process is known as gluconeogenesis.
Gluco being glucose neo being new and genesis being creation.
Creating “new” glucose for the purpose of cellular respiration.
This is
just one example of the intricacy that our bodies naturally possess to allow us
to grow, reproduce and be evolutionarily successful. This process shows the end
product of thousands of years of evolution that have solved the question. What
if there is not enough glucose in the environment to consume to sustain life? The
body has figured out a way to create new glucose so that in times of famine
there is still enough to go around.
The
evolution that is required for these kinds of answers takes time though. I think
that because we have so many new problems that arise so quickly then our bodies
are not able to adjust and fix the problems itself. If we slowly adapted to
eating a highly refined sugar diet then maybe our bodies would have learned to
better control the excess sugars and things like diabetes would be less of an
abundant issue. However, because we have switched to eating a more refined diet
over a generation or two, instead of a millennium or two, we are not able to adequately
deal with such a sudden shift. This is not only apparent with glucose-related
disease, but look at what is happening with the sudden shift to an over-exposure to artificial light. This has happened even faster than a generation
it has happened in as short as 20 to 30 years. We are seeing that an increase in
artificial light exposure can lead to things like sleeping disorders, mood
disorders, and a whole host of psychological problems.
We see these kinds of problems day more and
more commonly and one great explanation as to why is an increase in light
affects our sleep patterns is Ayurveda. Ayurveda is the traditional Hindu
system of medicine, which is based on the idea of balance in bodily systems. This
means that when something like light exposure is increased, it not only affects
our eyes at the moment of exposure but it will continue to affect other parts
of our body that relies on light for signals for biochemical reactions and then
on to anything that is affected by those biochemical reactions.
A great
example of these reactions getting out of hand is diabetes. Diabetes is a disease
that occurs when there is an incorrect balance of glucose in the bloodstream
and not in the cell. When this occurs over long periods of time it's common to
see problems like heart disease, stroke, kidney damage, blindness, and nerve
damage. I find it fascinating that an imbalance of glucose in the bloodstream can
cause you to lose your sight. This shows that Ayurveda is a real concern and
that our bodies have very intricate pathways that are all interconnected. It is
not that excess blood sugar attacks the eyes resulting in blindness, it’s a far
more complicated chain of events that over time affects vision and other
aspects of the body that are not directly associated with cellular respiration
or blood glucose.
But we
as humans are designed to overcome challenges like this. It is called adaptation
and evolution. If we started off slowly “learning” how to handle excess blood
sugar then over generations and several thousands of years, it is likely that
diabetes would not be a problem, similar to the way that decreased glucose in the
bloodstream is not a problem.
