Role In Mental Health
Itâs hard to pinpoint a single cause of most mental health disorders and challenges. But they’re often linked to too much or too little dopamine in different parts of the brain. Examples include:
Schizophrenia. Decades ago, researchers believed that symptoms stemmed from a hyperactive dopamine system. Now we know that some are due to too much of this chemical in certain parts of the brain. This includes hallucinations and delusions. A lack of it in other parts can cause different signs, such as lack of motivation and desire.
ADHD. No one knows for sure what causes attention deficit hyperactivity disorder . Some research shows it may be due to a shortage of dopamine. This problem may be due to your genes. The ADHD drug methylphenidate works by boosting dopamine.
Drug misuse and addiction. Drugs such as cocaine can cause a big, fast increase of dopamine in your brain. That satisfies your natural reward system in a big way. But repeated drug use also raises the threshold for this kind of pleasure. This means you need to take more to get the same high. Meanwhile, drugs make your body less able to produce dopamine naturally. This leads to emotional lows when youâre sober.
Do Activities That Release Dopamine
Sex, drugs, and rock and roll. Want a jolt of dopamine straight in the feels? Start getting more of these things in your life.
We are only half kidding Just make sure you dont overdo it or youll risk addiction.
Remember, its all about balance. Your end goal is to live a lifestyle that promotes the healthiest version of yourself. No single activity is going to make you a dopamine machine.
Dopamine: The Pleasure Hormone
Dopamine is involved in a number of essential neurological & cognitive processes and affects our mood, pleasure and motivation. It significantly affects the motivation-reward-reinforcement cycle which influences our goal-directed behavior. Although a lot of research has been conducted on DA, there is still a lot to understand about how this neurotransmitter interacts with hormones and other neurotransmitters.
If you believe that you are experiencing DA deficiency or any associated ailments, then make sure to consult a doctor immediately.

Natural Ways To Balance Dopamine Levels
Dopamine levels are difficult to monitor since they occur in the brain, but there are ways to balance your dopamine levels without medication. The best way to balance your dopamine levels is to focus on healthy habits.
If youre over indulging in certain dopamine-producing activities like sex, technology, or gambling, then youll want to take intentional breaks, but if youre having trouble concentrating, feeling unmotivated or tired, then youll want to increase your dopamine production.
Latent Inhibition And Creative Drive
Dopamine in the mesolimbic pathway increases general arousal and goal directed behaviors and decreases latent inhibition all three effects increase the creative drive of idea generation. This has led to a three-factor model of creativity involving the frontal lobes, the temporal lobes, and mesolimbic dopamine.

Cellular Actions Of Dopamine
To affect its target cells, dopamine interacts with specific docking molecules on the target-cell surface. Dopamine receptor subtypes fall into two families: the D1-like family, which includes the receptor subtypes D1 and D5, and the D2-like family, which includes the receptor subtypes D2, D3, and D4. When dopamine interacts with these receptors, they activate certain proteins within the cell called G proteins. These proteins, in turn, can affect the activity of channels in the cell membrane that allow the flow of charged particles into and out of the cell. Changes in the activity of these ion channels make it either easier or more difficult to excite the cell. In addition, G proteins regulate the production of small signaling molecules within the cell.
Dopamine As A Treatment Target For Alcoholism
Researchers are also investigating whether drugs that normalize dopamine levels in the brain might be effective for reducing alcohol cravings and treating alcoholism.
In clinical trials in Sweden, alcohol-dependent patients who received an experimental drug called OSU6162, which lowers dopamine levels in rats, experienced significantly reduced alcohol cravings.
Pia Steensland, an associate professor at the Department of Clinical Neuroscience at the Karolinska Institutet and co-author of the studies, said the patients who received the drug reported not enjoying the first zip of alcohol as much as patients who did not receive the drug.
Interestingly, those with the poorest impulse control who would be considered most at risk of relapse after a period of sobriety responded best to the treatment.

What Parts Of The Brain Are Affected By Drug Use
Drugs can alter important brain areas that are necessary for life-sustaining functions and can drive the compulsive drug use that marks addiction. Brain areas affected by drug use include:
Some drugs like opioids also disrupt other parts of the brain, such as the brain stem, which controls basic functions critical to life, including heart rate, breathing, and sleeping. This interference explains why overdoses can cause depressed breathing and death.
Best Ways To Increase Dopamine Levels Naturally
Dopamine is an important chemical messenger in the brain that has many functions.
Its involved in reward, motivation, memory, attention and even regulating body movements .
When dopamine is released in large amounts, it creates feelings of pleasure and reward, which motivates you to repeat a specific behavior .
In contrast, low levels of dopamine are linked to reduced motivation and decreased enthusiasm for things that would excite most people .
Dopamine levels are typically well regulated within the nervous system, but there are some things you can do to naturally increase levels.

The Nervous System & Dopamine
To understand Parkinson’s, it is helpful to understand how neurons work and how PD affects the brain .
Nerve cells, or neurons, are responsible for sending and receiving nerve impulses or messages between the body and the brain. Try to picture electrical wiring in your home. An electrical circuit is made up of numerous wires connected in such a way that when a light switch is turned on, a light bulb will beam. Similarly, a neuron that is excited will transmit its energy to neurons that are next to it.
Neurons have a cell body with branching arms, called dendrites, which act like antennae and pick up messages. Axons carry messages away from the cell body. Impulses travel from neuron to neuron, from the axon of one cell to the dendrites of another, by crossing over a tiny gap between the two nerve cells called a synapse. Chemical messengers called neurotransmitters allow the electrical impulse to cross the gap.
Neurons talk to each other in the following manner :

Where Is Dopamine Produced
Neurons in the region at the base of the brain produce dopamine in a two-step process. First, the amino acid tyrosine is converted into another amino acid, called L-dopa. Then L-dopa undergoes another change, as enzymes turn it into dopamine.
Too little dopamine causes the stiff movements that are the hallmark of Parkinsons disease. Although depression is more often linked to a lack of serotonin, studies find that a dopamine deficiency also contributes to a down mood. In particular, people with depression often suffer from a lack of motivation and concentration.
Because dopamine is made from tyrosine, getting more of this amino acid from food could potentially boost dopamine levels in your brain. There is evidence that a diet rich in tyrosine also may improve memory and mental performance.
Foods high in tyrosine include:
- chicken and other types of poultry
- dairy foods such as milk, cheese, and yogurt
- pumpkin and sesame seeds
There is also some evidence that the brain releases more dopamine when we meditate. The change in consciousness that occurs during meditation may trigger its release.
Dopamine is just one of the four feel-good hormones. To learn more about the others and how they work, head to the beginning of this series.
Outside The Nervous System
Dopamine does not cross the bloodbrain barrier, so its synthesis and functions in peripheral areas are to a large degree independent of its synthesis and functions in the brain. A substantial amount of dopamine circulates in the bloodstream, but its functions there are not entirely clear. Dopamine is found in blood plasma at levels comparable to those of epinephrine, but in humans, over 95% of the dopamine in the plasma is in the form of dopamine sulfate, a conjugate produced by the enzyme sulfotransferase 1A3/1A4 acting on free dopamine. The bulk of this dopamine sulfate is produced in the mesentery that surrounds parts of the digestive system. The production of dopamine sulfate is thought to be a mechanism for detoxifying dopamine that is ingested as food or produced by the digestive processlevels in the plasma typically rise more than fifty-fold after a meal. Dopamine sulfate has no known biological functions and is excreted in urine.
Beyond its role in modulating blood flow, there are several peripheral systems in which dopamine circulates within a limited area and performs an exocrine or paracrine function. The peripheral systems in which dopamine plays an important role include the immune system, the kidneys and the pancreas.

How Can I Adjust My Dopamine Levels
You can boost a low level of dopamine by addressing the cause of the problem. This could be a mental illness, stress, not getting enough sleep, drug abuse, being obese, or eating too much sugar and saturated fat. Low dopamine can also be caused by a problem with the adrenal glands.
You can increase your dopamine levels naturally by eating a healthy diet, including foods rich in L-Tyrosine . These include almonds, avocados, bananas, beef, chicken and eggs. Turmeric, vitamin D, magnesium and omega-3 supplements are also claimed to increase dopamine levels.
Activities that make you feel good will also raise dopamine. These include exercising, meditating, having a massage and getting enough sleep. Thinking about your achievements and all the good things in your life can also help.
People with Parkinsons disease are usually given medicines to boost their dopamine levels. These can often cause a big improvement in symptoms.

The Science Behind Supplementation
Dopamine is your bodys way of rewarding you for doing the things it needs to do.
It incentivizes us to make babies, go to work, interact with others, and achieve goals everything right down to getting out of bed in the morning . Thats why low levels of it are associated with depression, lack of motivation, and addiction.
But you cant just put pure dopamine into your brain. Dopamine supplements are actually the essential amino acids phenylalanine and tyrosine. Your body then synthesizes dopamine from them. Its just like how we make gas from crude oil. Cars run on gas, but weve got to refine crude oil into gas first. You wouldnt put crude oil into your gas tank, right?
So your goal should be to supplement your L-dopa, tyrosine, and phenylalanine levels. But heres why supplementing is not the catch-all solution to your low dopamine levels.
What Does Dopamine Do
Now that weve covered the background science, lets take a look at how dopamine impacts daily life.
Dopamine is your motivation molecule.
It boosts your drive, focus, and concentration.
It enables you to plan ahead and resist impulses so that you can achieve your goals.
It gives you that I did it! lift when you accomplish what you set out to do.
It gets your competitive juices flowing and provides the thrill of the chase in all aspects of life business, sports, and love.
Additionally, dopamine is in charge of your pleasure-reward system.
It allows you to experience feelings of enjoyment, bliss, and even euphoria.
Too little dopamine can leave you unfocused, unmotivated, lethargic, and even depressed.
Dopamine is so critical to motivation that dopamine-deficient lab mice lack the motivation to eat.
Without dopamine, they will choose to starve even when food is readily available.
HOW’S YOUR MOOD?
Prescription and Recreational Drugs
Theres an entire category of prescription drugs called dopamine antagonists that work by binding to dopamine receptors, thereby blocking dopamine activity.
Three main types of drugs fall into this category: tricyclic antidepressants, drugs for nausea and vomiting, and some antipsychotics.
Recreational drugs including alcohol, marijuana, cocaine, methamphetamine, ecstasy, amphetamines, and LSD affect dopamine processing pathways, leading to a dopamine roller coaster ride, up then down.
