Dopamine is generally known as a neurotransmitter that can play a central role in our ability to function, supporting the reward center in our brain—and possibly controlling the way we might feel and behave.
A lack of dopamine can lead to a variety of mental and physical health challenges, including high blood pressure, depression, substance use disorder and Parkinson’s disease. Low dopamine levels can be successfully addressed in many, however, so that the negative effects of a deficiency are limited.
In this article, we’ll cover dopamine, its possible range of effects and the importance of addressing a potential deficiency in this brain chemical.
What is dopamine?
Dopamine is generally defined as a type of neurotransmitter—known by many as a messenger that can help deliver impulses to certain parts of the body. Often called the “happy hormone”, dopamine can be connected to our feelings of pleasure and satisfaction. It may also be partially responsible for helping us recognize the reward of a certain action, which can motivate us to achieve that end.
Dopamine is also generally classed as a monoamine neurotransmitter, which is one of four different types of known neurotransmitters. Neurotransmitters can allow impulses from nerve cells to arrive at their targets, which could be glands, muscle cells, or other nerve cells.
Dopamine can also help us to learn new things, focus on tasks, and move our bodies.
Having dopamine deficiencies
Experiencing a dopamine deficiency can be challenging, potentially making it harder for you to set goals or motivate yourself. For example: A lack of dopamine can lead to complex feelings and trouble controlling your emotions.
Low dopamine levels can also be linked to several different mental, physical, and neurodegenerative health conditions, such as depression, restless leg syndrome, and Parkinson’s disease. People who live with lower dopamine levels may also be more susceptible to developing a substance use disorder.
Symptoms of having a low level of dopamine
Possible signs of a dopamine deficiency can vary depending on the cause of the deficiency for that specific person. For example, those who have low levels of dopamine connected to Parkinson’s disease may experience different symptoms than those whose low dopamine is linked to a mental health condition, like depression.
Possible symptoms of a dopamine deficiency
- Muscle cramps, aches, pains and stiffness
- Constipation
- Lack of energy and motivation
- Difficulty eating and swallowing
- Chronic or recurring heartburn
- Pneumonia
- Mood swings
- Nervousness
- Lowered sex drive
- Delusions
The role of dopamine in Parkinson's disease
It can be helpful to note that a lack of dopamine is not generally considered a unifying cause of any of the above-mentioned related conditions (such as Parkinson’s), even though it may partially contribute to their development.
Causes of low levels of dopamine
The causes for low dopamine levels can range depending on the individual cases and presentations. Often, a dopamine deficiency can be connected to a physical or mental health condition. There is also evidence that suggests that stress, particularly chronic stress, can affect the brain’s ability to produce dopamine.
Brain receptors and dopamine transport
It can be important to remember that there may not be a “cause” for low dopamine in some cases. This might mean that dopamine levels may appear to be normal, but the receptors in the brain responsible for transporting dopamine might have alterations that can keep them from receiving it.
Drugs and diet
The use of some drugs can also alter the levels of dopamine in the brain or change how effectively the brain uses dopamine. So, too, can a person’s diet. For example: A diet high in sugar and saturated fat and low has been linked to altered dopamine levels in the brain.
Effects of excess dopamine
While some people might experience decreased dopamine levels, others may experience a surplus of dopamine, which can also have mental and physical effects.
Excess dopamine can have many possible causes, such as using a specific medication to treat a condition connected to lower dopamine levels (like Parkinson's disease). It can also be caused by a lack of sleep in some.
A dopamine surplus has been linked to addictive behavior, such as compulsive gambling, drug and alcohol use (including tobacco), and addictions to food.
Excess dopamine, if left untreated, can lead to serious complications—such as schizophrenia and other mental health conditions.
Having balanced dopamine levels can help to ensure that we’re able to function physically, mentally and emotionally. If we have too little dopamine, we may struggle to get things done and can experience symptoms that can be commonly correlated to certain mental health conditions—such as depression or ADHD. If we have too much dopamine, we may become stressed, harbor excess energy and develop other complications.
Treating a dopamine deficiency
Typically, to manage a dopamine deficiency, medical and mental health professionals might focus on addressing the condition it is linked to. For example: If an individual is diagnosed with depression, a healthcare professional may create a treatment plan that includes therapy and medication meant to help manage dopamine levels.
Medications for low dopamine levels
There are several different medications that can help treat dopamine deficiency and its possible underlying health concerns. For example: Certain depression medications help moderate the reuptake of dopamine, possibly creating elevated levels of the neurotransmitter in the brain.
Dopamine agonists for other conditions like Parkinson’s disease
For other conditions (e.g., Parkinson’s disease or restless leg syndrome), healthcare professionals may prescribe dopamine agonists—otherwise known as drugs that can mimic dopamine in the brain. Please note that many may find the most benefit from medication when it is given under the supervision of their licensed medical professional.
Psychotherapy to address related mental health disorders
Psychotherapy can also help one to manage the emotional and mental effects of low dopamine levels. Often, a therapist can help motivate the individual, address a related mental health disorder and provide tips for navigating a dopamine deficiency at home. Additionally, physical therapy can help someone with low dopamine levels to possibly alleviate muscle issues that may arise out of a deficiency.
Lifestyle changes to boost the levels of dopamine
Certain lifestyle changes have been scientifically suggested to increase dopamine levels, such as exercising and meditating. These activities can boost dopamine naturally and improve the individual’s overall mood.
Online therapy can help with low dopamine levels

What causes a deficiency of dopamine in the brain?
A deficiency of dopamine in the brain can occur due to various factors, including both genetic and environmental influences.
Causes of having a low level of dopamine
Some of the common causes and factors associated with dopamine deficiency include:
- Neurological Conditions: Parkinson's disease is a neurodegenerative disorder characterized by the progressive loss of dopamine-producing neurons in the substantia nigra region of the brain. This loss of neurons leads to a significant deficiency of dopamine, resulting in motor symptoms such as tremors, rigidity, bradykinesia (slowness of movement), and postural instability.
- Genetic Factors: Rare genetic mutations or variations can lead to impaired dopamine synthesis or metabolism, causing dopamine deficiencies. These genetic factors can sometimes be a contributing factor in certain neuropsychiatric disorders.
- Medications: Some medications can affect dopamine levels. For example, certain antipsychotic medications (dopamine receptor antagonists) work by blocking dopamine receptors, which can reduce dopamine activity in the brain. Prolonged use of these medications can contribute to dopamine deficiency-related side effects and a reduction in dopamine and dopamine transporter molecules that enable dopamine cell activation.
- Substance Use: Chronic substance or drug abuse, particularly with drugs like cocaine or amphetamines, can lead to reduced dopamine function in the brain. The repeated use of these drugs can disrupt the brain's natural dopamine regulation.
- Dietary Factors: Inadequate intake of the amino acid tyrosine, which is a precursor to dopamine, can potentially affect dopamine production. A balanced diet that includes tyrosine-rich foods can help support dopamine synthesis.
- Stress and Chronic Stress: Prolonged exposure to high levels of stress can negatively impact dopamine function. Chronic stress can lead to changes in the brain that affect the release and regulation of dopamine.
- Aging: The aging process itself can result in a natural decline in dopamine levels. This age-related decline may contribute to changes in cognitive function and mood in some individuals.
Is ADHD a lack of dopamine?
Attention deficit hyperactivity disorder (ADHD) is a complex neurodevelopmental disorder, and its exact underlying causes are not fully understood. While dopamine dysregulation is believed to play a role in ADHD, it may involve more than a "lack of dopamine." Instead, ADHD likely involves multiple neurotransmitter systems and genetic factors.
How do you fix low dopamine levels?
Fixing low dopamine levels often involves a combination of lifestyle changes, therapeutic interventions, and, in some cases, medication prescribed by a healthcare professional.
Strategies to help with dopamine deficiencies
Here are some strategies that may help increase dopamine levels naturally:
- Diet and Nutrition
- Exercise
- Sleep
- Stress Management
- Social Interaction
- Set and Achieve Goals
- Novelty and Exploration
- Music and Art
- Sunlight Exposure
- Mindfulness and Meditation
How do I know if I have dopamine deficiency?
Determining whether you have a dopamine deficiency depends on a thorough evaluation by a healthcare professional, such as a neurologist, psychiatrist, or primary care physician. Dopamine deficiency is often associated with specific neurological or psychiatric symptoms, but these symptoms can also be indicative of various other medical conditions. Here are some signs and symptoms that may suggest the possibility of dopamine system dysregulation:
- Tremors: Involuntary shaking, typically in the hands or fingers.
- Rigidity: Stiffness or inflexibility of muscles.
- Bradykinesia: Slowness of movement.
- Postural Instability: Difficulty maintaining balance and coordination.
- These movement-related symptoms are often associated with conditions like Parkinson's disease, where there is a significant loss of dopamine-producing neurons.
- Depression: Persistent feelings of sadness, hopelessness, and lack of interest or pleasure in activities.
- Apathy: A lack of motivation, interest, or enthusiasm for daily activities.
- Anhedonia: An inability to experience pleasure from normally enjoyable activities.
- Fatigue: Excessive tiredness and lack of energy.
These symptoms can be seen in conditions where there may be disruptions in dopamine pathways or regulation, such as certain types of depression or other mood disorders.
- Cognitive Impairments: Difficulty with memory, attention, and executive functions (e.g., planning and decision-making) can occur in conditions where there is a disturbance in dopamine activity within the prefrontal cortex.
- Psychiatric Symptoms: Psychiatric conditions like schizophrenia may involve dopamine dysregulation, leading to symptoms such as hallucinations, delusions, and disorganized thinking.
- Restlessness and Impulsivity: Conditions like attention deficit hyperactivity disorder (ADHD) are associated with difficulties in regulating dopamine in the prefrontal cortex, leading to symptoms of restlessness, impulsivity, and inattention.
It may be important to note that these symptoms are not exclusive to dopamine-related issues, and many other medical conditions can present with similar signs. Therefore, a comprehensive assessment by a healthcare provider is essential to determine the underlying cause of any symptoms you may be experiencing.
How can I get dopamine naturally?
To naturally increase dopamine levels, focus on activities and practices that promote overall well-being. Engage in regular exercise, especially aerobic activities like running or swimming, which can boost dopamine levels. Consume a balanced diet rich in tyrosine-containing foods, such as lean proteins, dairy, nuts, and seeds. Prioritize quality sleep to ensure proper neurotransmitter regulation. Manage stress through relaxation techniques like meditation and deep breathing. Social interactions, setting and achieving goals, and pursuing hobbies you enjoy can also stimulate dopamine release. Lastly, exposure to natural sunlight and engaging with music, art, or other creative pursuits can contribute to an overall sense of reward and satisfaction, supporting healthy dopamine function.
What foods have dopamine?
Dopamine itself is not found in foods, as it is a neurotransmitter produced in the brain. However, certain nutrients and dietary components can support the synthesis and function of dopamine in the brain. These dietary neurotransmitters include:
- Tyrosine: Tyrosine is an amino acid and a precursor to dopamine. Foods rich in tyrosine can provide the building blocks necessary for dopamine synthesis. Sources of tyrosine include:
- Lean meats (e.g., chicken, turkey, lean beef)
- Fish (e.g., salmon, trout, tuna)
- Dairy products (e.g., milk, yogurt, cheese)
- Eggs
- Soy products (e.g., tofu, soybeans)
- Nuts and seeds (e.g., almonds, sunflower seeds)
- Phenylalanine: Phenylalanine is another amino acid that can be converted into tyrosine, which, in turn, can be used to produce dopamine. Foods rich in phenylalanine include many of the same sources as tyrosine-rich foods.
- Fruits and Vegetables: Certain fruits and vegetables contain compounds that can support dopamine function indirectly by safeguarding dopamine-producing neurons or promoting overall brain health. These include:
- Blueberries
- Spinach and other leafy greens
- Broccoli
- Avocado
- Beets
- Turmeric
- Antioxidants: Antioxidants help protect dopamine-producing neurons from oxidative stress. Foods rich in antioxidants can contribute to overall brain health. Examples include:
- Berries (e.g., blueberries, strawberries)
- Dark chocolate (in moderation)
- Green tea
- Citrus fruits (e.g., oranges, grapefruits)
- Protein-Rich Foods: Consuming adequate protein from various sources, including lean meats, fish, and plant-based options like legumes and tofu, can help provide the amino acids needed for neurotransmitter synthesis, including dopamine.
Does caffeine increase dopamine?
Caffeine can increase dopamine levels in the brain. Caffeine is a central nervous system stimulant that works by blocking the action of a neurotransmitter called adenosine. Adenosine is known for promoting relaxation and sleepiness in the brain. When you consume caffeine, it competes with adenosine for binding to its receptors, effectively blocking adenosine's calming effects.
As a result of this adenosine-blocking action, caffeine leads to increased release of several neurotransmitters, including dopamine. The release of dopamine, along with other neurotransmitters like norepinephrine, contributes to the stimulating effects of caffeine. This is why caffeine can help improve alertness, concentration, and mood.
Is dopamine a mental illness?
No, dopamine is not a mental illness. Dopamine is a neurotransmitter—a chemical messenger in the brain—involved in various important functions, including mood regulation, reward processing, and movement control. Dopamine itself, as well as the neurotransmitters serotonin and norepinephrine, are not mental disorders or illnesses.
Mental illnesses are medical conditions that affect a person's thoughts, emotions, behavior, and overall mental well-being. Examples of mental illnesses include major depressive disorders, anxiety disorders, schizophrenia, bipolar disorder, and attention deficit hyperactivity disorder, ADHD, among others.
While dopamine dysregulation is associated with some mental health conditions (e.g., depression, schizophrenia, and ADHD), it is just one element of the complex neurobiology underlying these disorders. Mental illnesses result from a combination of genetic, environmental, neurological, and psychological factors.
What activities increase dopamine?
Engaging in certain activities and experiences can lead to an increase in dopamine release in the brain. Dopamine is often associated with the brain's reward and pleasure systems. Here are some activities that can stimulate the release of dopamine:
- Exercise: Regular physical activity, especially aerobic exercise like running, swimming, and dancing, can increase dopamine levels. This is often referred to as the "runner's high."
- Listening to Music: Music, especially music that elicits positive emotions or anticipation, can lead to the release of dopamine. Music with a strong emotional connection can be particularly rewarding.
- Eating Delicious Food: Consuming tasty and satisfying food, especially when hungry, can trigger dopamine release. This is a natural mechanism that encourages us to eat and seek out nutrition.
- Sexual Activity: Sexual arousal and orgasm can lead to a surge of dopamine, contributing to feelings of pleasure and satisfaction.
- Social Interaction: Positive social interactions, such as spending time with loved ones or receiving social validation, can trigger dopamine release. Social bonding is closely tied to the brain's reward system.
- Accomplishment and Achievement: Setting and achieving goals, whether they are personal or professional, can result in a sense of accomplishment and a release of dopamine.
- Novelty and Exploration: Trying new experiences or exploring unfamiliar environments can activate the brain's reward system, as it processes new information and anticipates potential rewards.
- Rewarding Substances: Certain substances, such as drugs of abuse (e.g., cocaine, amphetamines, opioids), can cause a significant release of dopamine. However, the use of such substances can lead to addiction and serious health consequences.
- Gaming and Gambling: Activities that involve chance, competition, or reward systems, such as video gaming and gambling, can lead to dopamine release.
- Anticipation and Surprise: The brain often releases dopamine in anticipation of a pleasurable experience or when something unexpected and positive happens.
What destroys dopamine receptors?
Dopamine receptors are essential components of the brain's reward and pleasure system, and their proper function is crucial for normal brain function. While dopamine receptors themselves are not typically "destroyed," they can be affected or altered by various factors and conditions, including:
- Neurological Conditions: Certain neurological disorders, such as Parkinson's disease, involve the degeneration of dopamine-producing neurons and, consequently, a reduction in the number of available dopamine receptors and dopamine transporters.
- Prolonged Substance Use: Chronic and excessive use of certain drugs, especially drugs of abuse like cocaine, amphetamines, and opioids, can lead to downregulation or desensitization of dopamine receptors. This means that the receptors become less responsive to dopamine, requiring more of the substance to achieve the same effect. Over time, this can lead to reduced dopamine receptor density and function.
- Medications: Some medications, such as antipsychotic medications (dopamine receptor antagonists), work by blocking dopamine receptors. Prolonged use of these medications can lead to alterations in dopamine receptor sensitivity.
- Genetic Factors: Certain genetic variations can affect the number and function of dopamine receptors, making some individuals more susceptible to dopamine-related conditions or alterations in receptor activity.
- Aging: The aging process itself can lead to changes in the density and sensitivity of dopamine receptors. This natural decline in receptor function is associated with age-related cognitive changes and motor impairments in some individuals.
- Environmental Toxins: Exposure to environmental toxins, including some pesticides and industrial chemicals, can potentially damage dopamine-producing neurons or affect dopamine receptor function.
- Neuroinflammation: Inflammatory processes in the brain, whether due to infections, autoimmune conditions, or other factors, can affect dopamine receptor function and overall neurotransmitter balance.
