Natural Ways to Balance Your Brain Chemistry

It's in human nature to feel sadness. Every life is filled with ups and downs, tragedy and comedy, kindness and cruelty. It is a part and parcel of who we are and an important part of our journey. But for some people, the struggles often don’t end with the event that triggered the sadness. Nowadays, more and more people are suffering from depression and other mental ailments, at young ages also, and the explanation goes well beyond a singular circumstance, or an individual's inability to be happy or find strength. In fact, most mental health problems that people face can be understood from a purely chemical standpoint.

The brain is essentially the chemical factory of the body, producing all the hormones that keep our bodies growing and sending out all the messages to keep our limbs moving. So its only natural that in some cases, this factory might face some difficulties while doing its job. After all, we are only beings of flesh, blood, and imperfection, not machines. But those imperfections are what give us the drive, the endurance and the passion to persevere against all odds and struggle even through the toughest of times. That, and television. 

 

With that brief moment of levity over, let’s get back to the topic at hand. What are some of the mental health problems that are now becoming more and more commonplace?

Well, there’s depression. We already covered that. There are various types of depression as well. One of the more severe ailments that some people face is Bipolar Disorder, usually marked by intense and often uncontrollable periodic mood swings and personality shifts. Anxiety and frequent panic attacks can also be extremely disruptive and can affect a person’s ability to function normally and interact with other people. 

 

There are also a large number of people world over who suffer from memory loss, both long and short term, which can also be caused by an irregular production of chemicals in the brain (when not caused by head injuries or drugs, pharmaceuticals and other). Even addiction has been linked to irregular brain chemistry. These problems can affect people of all ages, races, geographies, and backgrounds.

What Does Brain Chemistry Mean?  

So when we talk about brain chemistry, what chemicals are we talking about specifically? We are basically talking about hormones and neurotransmitters. Neurotransmitters are the messengers of the body, letting the various organs know how the brain wants them to act, through nerve cells. These neurotransmitters can be huge determinants in our emotions. The following are a few of the main hormones our brains produce that affect our emotional state: 

 

1) Dopamine

This hormone has a very important role to play as it is the communicator between neurons and nerve cells. It is also the chemical that controls our motor function and drive. Dopamine is the hormone that keeps you motivated, active and focused on the task at hand and the world around you. Needless to say, it is a very important neurotransmitter, and lower levels of dopamine can result in depression, fatigue, and anxiety. High levels of dopamine, on the other hand, can result in addiction, largely because most addictive substances, from video games and coffee to alcohol and narcotics, are usually designed to increase dopamine levels drastically.

2) Serotonin

Also commonly known as the happy hormone, Serotonin is responsible for the joyful sensations we experience in life. Low levels of serotonin have been a major factor linked with depression. This is because problems can arise with respect to neuron inhibitors, that are in the brain to regulate the production of these hormones, and inhibit them where necessary. But in some cases, the production of serotonin can become too low as a result, which is why most anti-depressants are created with the intent to stop inhibitors from reducing the production of serotonin. 

 

3) Melatonin

This is the hormone that helps you sleep at night. It is produced by the pineal gland located in the center of the brain. Our sleep cycles, in general, are regulated by the suprachiasmatic nucleus (SCN), a center in the hypothalamus that sends signals to other parts of the brain. On exposure to darkness, the pineal gland receives a signal from the SCN and begins to actively produce melatonin. As the melatonin levels in your bloodstream increase, you steadily become drowsier. And the internal clock of the human body is usually pretty strict, as melatonin stays in the body normally from 9 pm to 9 am. Irregular production of melatonin can result in insomnia, fatigue and even depression in cases of excessive sleeping.

4) Oxytocin

This is another hormone brought to us courtesy of the hypothalamus and with the assistance of the pituitary gland. It plays a major role in how we interact with people and react to sexual arousal, giving it the name “the cuddle hormone” or “the love hormone”. It can also affect our ability to trust and high amounts can lead to anxiety and even addictive tendencies. It also has gender-specific effects, affecting the production of testosterone in the testes, as well as playing a huge role in the process of labor, childbirth, and child-rearing.

5) Endorphin

These are the chemicals of the body produced to give you an almost morphine-like rush. That is why many athletes often experience what is called the “runner’s high”, a sense of euphoria caused by increased production of endorphins due to vigorous exercise. This hormone affects the way the human body perceives pain and can act as an analgesic and a natural pain reliever. In some cases, it even works as a sedative, allowing the body to rest after completion of a strenuous activity.

6) Adrenaline  

Also known as epinephrine, this hormone is produced in the center of the adrenal glands known as the medulla. Adrenaline can also be produced by certain neurons in the central nervous system. Once in the bloodstream, it can have varying effects on different organs, usually activating the “fight or flight” instinct in the body. Adrenaline can affect the body in numerous different ways, from enlarging of the pupils to increase the heart rate and blood flow to different areas of the body. As you can guess, low levels of this hormone could make your lethargic, while too much can make your body and mind go into overdrive. 

 

7) Acetylcholine

This is one very important neurotransmitter, and in fact, among the first neurotransmitters discovered by scientists. Found commonly in both the central and peripheral nervous systems, which makes this chemical of such vital importance is that it stimulates the contraction of our muscles. Essentially all behavior and almost all movement comes down to how this particular neurotransmitter sends across its message, and what that message is. Naturally, if this hormone is in large or short supply, it can lead to some strange and almost unexplainable behavior.

8) Gamma-Aminobutyric Acid (GABA)

This neurotransmitter plays the very important role of a neural inhibitor and regulator, reducing, where possible, the activities of nerve cells and neurons. In that way, Gamma-Aminobutyric Acid is an essential determinant of our cognitive abilities and behavior. They work to keep neurons from becoming overexcited, which could potentially reduce anxiety and panic. A low-level of this neurotransmitter can cause disorders ranging from insomnia to depression and even schizophrenia. 

 

9) Glutamate

This non-essential amino acid is released by nearly half of all the brains, synaptic agents. But its a more local neurotransmitter that never leaves the blood-brain barrier (which is the wall designed to protect the brain). It is specifically associated with our ability to remember and learn, making it a major player in the development of the brain. Increased presence of glutamate in the human body has been linked with various ailments, like multiple sclerosis, Alzheimer’s and Parkinson;s Disease, while low levels can be associated with Obsessive Compulsive Disorder, Schizophrenia, and Autism.

10) Norepinephrine

This hormone is a variant of adrenaline and is also known as noradrenaline. Much like its counterpart, it is heavily linked with the “fight or flight” instinct of the human body. This type of neurotransmitter sends messages to the skeletal muscles of the body to increase the force of contractions, as well as contractions of the heart. It effectively prepares our body to react to a threatening situation, whatever that reaction may be. 

 

Natural Remedies For Keeping Your Brain Chemistry Balanced 

Now that we know what really goes on in our brains, and how it affects our happiness, sadness, physical behavior, energy levels, focus and so many other aspects of living and feeling, what are some of the natural remedies available that can help you self-regulate the production of these hormones in your brain? 

 

1. Get Moving

Regularly exercising is fantastic for the body and the brain. It increases the production of endorphin in the body, making you happy and euphoric, a mood-changer right there, and gets the adrenaline pumping through your bloodstream. The increased muscle movement will strengthen you physically and mentally.

2.Appreciate the Sun

Well, even if you don’t appreciate it, just make sure you get a little of it every day. It can improve your state of mind drastically. Sunlight, when absorbed through the skin, results in an increased production of serotonin by the brain. Just fifteen minutes a day in the sun, and you’ll understand why it’s called the “feel-good” hormone. 

 

 3. Let go of Stress

Easier said than done, yes. But definitely worth working towards, because stress is closely linked to low levels of GABA and increased amounts of norepinephrine and oxytocin. Don’t worry, there are numerous great ways to cope with stress.

4. Give yourself a bedtime  

Even if you don’t feel like you need to sleep, your brain definitely does. The brain produces melatonin, which will make you drowsier as the sunsets. Not only that, but the brain requires strength, energy, and fuel to produce the other hormones that make our bodies function healthily, and avoid struggling with fatigue and exhaustion. 

 

5. Watch your diet

Most chemicals produced by the brain are also found in numerous foods, so it's important to eat carefully and healthily. Caffeine, meat, bananas, chocolate and beets can increase the production of dopamine in the body, while broccoli, brown rice, fish, nuts, and even lentils can increase the amount of GABA produced by the brain.

New Study Reveals Molecular Signs of Parkinson's Disease

Parkinson’s Disease is a widespread chronic health issue that causes the degeneration of the central nervous system, which severely affects motor functions over time in addition to causing a number of other symptoms, including cognitive impairment, depression, fatigue, and sleeping problems. This disease is unfortunately fatal and causes a gradual degradation of the body and mind, though most of the symptoms can be managed and staved off by taking the right combination of medicine and possibly surgery.

While there is much information available about the treatments and symptoms of this disease in both its early stages and more advanced stages, the cause of Parkinson’s and it’s molecular structure have only just begun to be understood in this recent study.

 The Development of Parkinson’s Disease

Parkinson’s Disease is identified by the gradual degeneration of the central nervous system causing muscle rigidity, slow movements, and imbalance. The development of this disease is closely related to the production of neurons, neurotransmitters, and hormones that play a major role in motor functions.

The main chemical produced by the brain that contributes to motor function is dopamine, so when the nerve endings that produce dopamine become impaired or die, the motor system suffers and steadily degrades. Another set of neurotransmitters that become impaired in a person suffering from Parkinson’s disease are the nerve-endings that produce norepinephrine.

This particular chemical is one of the main messengers of the nervous system, controlling automatic bodily functions like blood pressure, heart rate, and digestion. It is largely the death and impairment of these neurotransmitters that lead to various progressive symptoms of Parkinson’s. However, the exact cause of neuronal failure remains unknown.

Parkinson’s disease affects nearly 500,000 people, and those numbers are, sadly, on the rise. While 90% of patients diagnosed are above the age of 60, the remaining 10% are within the 21-50 age bracket. It is these early cases that create the most worry, and at the same time, they show the most potential for identifying the molecular changes to the body that occur at the earliest stages of Parkinson’s disease.

What the Study Revealed

The study, published on 27th January 2020 in the journal Nature Medicine, was focused on the symptoms and development of the disease in young patients between the ages of 21 and 50. The study was conducted by a team of researchers from Cedars-Sinai and UCLA, and it first began by harvesting and generating special stem cells from young patients suffering from Parkinson’s. These stem cells are called induced pluripotent stem cells (iPSCs for short), and they are created by turning back the clock on adult cells by turning them into primitive embryonic cells.

These embryonic cells, iPSCs, can then produce genetically identical cells, replicating any type of cell in the human body. Using the iPSCs, the dopamine neurons of early-onset Parkinson’s patients were replicated, cultured in a dish, and analyzed. The goal, according to the senior author of the study Dr. Clive Svendsen, was to take the cells back to the earliest stages of their development and observe these dopamine neurons in the earliest stages of the disease, prior to major impairments.

Two major observations were detected. The first was a build-up of a protein commonly found in forms of Parkinson’s disease called alpha-synuclein in the neurons. The second observation was the malfunctioning of a number of lysosomes. Lysosomes are tiny sacs of enzymes in the cell that aid in digestion by acting as waste disposal systems, or “trash can” organelles that break down and dispose of proteins.

It could, therefore, be reasonably assumed that when the malfunctioning of these lysosomes occurs, it results in the accumulation of the alpha-synuclein protein in neuronal cells.

This technique and these observations show the first signs of early-onset Parkinson’s, which would likely imply that the build-up of alpha-synuclein over 2 or 3 decades could cause the progression of the symptoms of the disease. The greater the accumulation, the more severe the symptoms.
 
A Great Sign of Progress
These abnormalities are now being studied to determine their presence in other forms of Parkinson’s disease. The technique described in this study not only provided the team of researchers a method that helps us understand the progression of the disease on a molecular level, but also a means of drug testing.

The iPSCs were used to test a variety of drugs, one of which was found to reduce the high levels of alpha-synuclein. This drug, PEP005, was tested in both the dopamine neurons in the dish, as well as in lab mice, and was found to reduce alpha-synuclein levels. The benefit of this drug is that it has already been approved by the FDA (United States Food and Drug Administration) as a treatment for precancerous tumors of the skin.  

An additional surprising result of using the drug, PEP005, is an abnormal increase in the levels of an active protein called kinase C. However, the relation of this protein to Parkinson’s disease is still undiscovered. Experiments are being conducted to determine how the drug PEP005 might be used to treat or even prevent early-onset symptoms of Parkinson’s.

What Makes This Research So Important
Recent Study Uses Special type of stem cells to discover early signs of Parkinson's disease at younger ages


Dr. Michele Tagliati, professor and vice-chair of the Department of Neurology at Cedars-Sinai, director of the Movement Disorders Program and a co-author of the study stated that “Young-onset Parkinson's is especially heartbreaking because it strikes people at the prime of life… This exciting new research provides hope that one day, we may be able to detect and take early action to prevent this disease in at-risk individuals."

This study shows great potential for the future of Parkinson’s disease and in the discovery of possible preventive measures, treatments, and cures. This joint effort between Cedars-Sinai and UCLA also marks an important milestone in collective medical advancement.

As Dr. Shlomo Melmed of Cedars-Sinai said, “This research is an outstanding example of how physicians and investigators from different disciplines join forces to produce translational science with the potential to help patients.” This study marks one of many incredible collaborative programs from the past and hopefully for the future on Parkinson’s Disease.

Neuroscientists Reveal How the Brain Selectively Remembers New Places

When you enter a room, your brain is bombarded with sensory information. If the room is a place you know well, most of this information is already stored in long-term memory. However, if the room is unfamiliar to you, your brain creates a new memory of it almost immediately.

MIT neuroscientists have now discovered how this occurs. A small region of the brainstem, known as the locus coeruleus, is activated in response to novel sensory stimuli, and this activity triggers the release of a flood of dopamine into a certain region of the hippocampus to store a memory of the new location.

“We have the remarkable ability to memorize some specific features of an experience in an entirely new environment, and such ability is crucial for our adaptation to the constantly changing world,” says Susumu Tonegawa, the Picower Professor of Biology and Neuroscience and director of the RIKEN-MIT Center for Neural Circuit Genetics at the Picower Institute for Learning and Memory.

“This study opens an exciting avenue of research into the circuit mechanism by which behaviorally relevant stimuli are specifically encoded into long-term memory, ensuring that important stimuli are stored preferentially over incidental ones,” adds Tonegawa, the senior author of the study.

Akiko Wagatsuma, a former MIT research scientist, is the lead author of the study. 

New places
In a study published about 15 years ago, Tonegawa’s lab found that a part of the hippocampus called the CA3 is responsible for forming memories of novel environments. They hypothesized that the CA3 receives a signal from another part of the brain when a novel place is encountered, stimulating memory formation.

They believed this signal to be carried by chemicals known as neuromodulators, which influence neuronal activity. The CA3 receives neuromodulators from both the locus coeruleus (LC) and a region called the ventral tegmental area (VTA), which is a key part of the brain’s reward circuitry. The researchers decided to focus on the LC because it has been shown to project to the CA3 extensively and to respond to novelty, among many other functions.

The LC responds to an array of sensory input, including visual information as well as sound and odor, then sends information on to other brain areas, including the CA3. To uncover the role of LC-CA3 communication, the researchers genetically engineered mice so that they could block the neuronal activity between those regions by shining light on neurons that form the connection.

To test the mice’s ability to form new memories, the researchers placed the mice in a large open space that they had never seen before. The next day, they placed them in the same space again. Mice whose LC-CA3 connections were not disrupted spent much less time exploring the space on the second day, because the environment was already familiar to them. However, when the researchers interfered with the LC-CA3 connection during the first exposure to the space, the mice explored the area on the second day just as much as they had on the first. This suggests that they were unable to form a memory of the new environment.

The LC appears to exert this effect by releasing the neuromodulator dopamine into the CA3 region, which was surprising because the LC is known to be a major source of norepinephrine to the hippocampus. The researchers believe that this influx of dopamine helps to boost CA3’s ability to strengthen synapses and form a memory of the new location.

They found that this mechanism was not required for other types of memory, such as memories of fearful events, but appears to be specific to memory of new environments. The connections between the LC and CA3 are necessary for long-term spatial memories to form in CA3.

“The selectivity of successful memory formation has long been a puzzle,” says Richard Morris, a professor of neuroscience at the University of Edinburgh, who was not involved in the research. 

“This study goes a long way toward identifying the brain mechanisms of this process. Activity in the pathway between the locus coeruleus and CA3 occurs most strongly during novelty, and it seems that activity fixes the representations of everyday experience, helping to register and retain what’s been happening and where we’ve been.”

Choosing to remember
This mechanism likely evolved as a way to help animals survive, allowing them to remember new environments without wasting brainpower on recording places that are already familiar, the researchers say.

“When we are exposed to sensory information, we unconsciously choose what to memorize. For an animal’s survival, certain things are necessary to be remembered, and other things, familiar things, probably can be forgotten,” Wagatsuma says.

Still unknown is how the LC recognizes that an environment is new. The researchers hypothesize that some part of the brain is able to compare new environments with stored memories or with expectations of the environment, but more studies are needed to explore how this might happen.

“That’s the next big question,” Tonegawa says. “Hopefully new technology will help to resolve that.”

The research was funded by the RIKEN Brain Science Institute, the Howard Hughes Medical Institute, and the JPB Foundation.
