Dopamine Deficiency and ADHD: Symptoms, Causes & Treatment

You know that feeling you get after finishing a big project at work or beating your own bench pressing record at the gym? That shear wave of joyous satisfaction that overtakes you? That’s dopamine flowing through your body.

Dopamine is a neurotransmitter produced in your brain which serves as a chemical messenger between your brain cells.

It plays an instrumental role in our pleasure and reward systems, affecting not only the id and the ego but also the part of our brain that regulates our ability to be productive.

Maybe you feel a constant sense of disappointment or confusion. Everything is depressing and nothing seems achievable.

Does this sound like your life? Are you down in the dumps and you don’t know why? If so, you could be suffering from dopamine deficiency.

Dopamine’s modulatory function is an inherent feature of all animals (including bipeds or humans).

There are several disorders that are related to dopamine deficiency, including dopamine transporter deficiency syndrome which affects one’s ability to move, and dopamine beta-hydroxylase deficiency, which inhibits the body’s ability to regulate body temperature and blood pressure.

But the average affliction is straight up dopamine deficiency which normally results in a range of mild to extreme symptoms.

Common Symptoms of Low Dopamine

The following are the most commonly reported symptoms associated with dopamine deficiency. If you are experiencing one or more of these symptoms, you may be suffering from low dopamine levels.

ADHD and Anxiety

Low dopamine ADHD and anxiety is one of the most common problems that ail those with low dopamine levels. While high dopamine levels can also cause one to experience panic attacks and restlessness, dopamine deficiency seriously unnerves the afflicted and can lead to a range of stress disorders, making it nearly impossible to focus or relax around others.

Cognitive Impairment

It’s hard to perform well when you lack proper dopamine levels. If your work is suffering and your boss has called you out for underperforming, this may be due to insufficient dopamine. An inability to complete mentally demanding tasks and poor memory are two symptoms of a brain that’s deficient in dopamine.


Learning new things becomes a chore if you don’t have a sufficient amount of dopamine in your body. New things won’t make as much sense and confusion will set in. Excessive brain fog is not unheard of among those who have been diagnosed with low dopamine levels. An increase in dopamine promotes psychomotor vigilance and can diminish this confusion.


Persons with low dopamine levels are far less likely to be capable of creative thought than those with a sufficient amount of dopamine. A lack of dopamine density results in a lack of divergent thinking because the dopamine deficient person’s brain is not able to filter out thoughts as well as a healthy individual.


Dopamine is, in part, responsible for our emotional expression and helps us to feel. Without an adequate amount of dopamine, you may feel like all of the color and excitement has been drained out of your life. If you’re a Woody Allen fanatic, maybe you’ve heard the word “anhedonia” and thought, “That’s me. I’m an anhedoniac.”

Anhedonia refers to the inability to feel pleasure, but that definition can just as accurately describe the depersonalization which occurs as a consequence of low dopamine levels.

In fact, some dopamine deficient people even feel like their core personality has changed against their will. They experience their life from a third-person perspective. Support groups online have discussed this depersonalization at length.

Depression (Mild or Severe)

This may be one of the single largest issues that dopamine deficient persons grapple with. It is also one of the reasons why it may take some doctors time to diagnose you as being dopamine deficient.

Depression is something that runs rampant throughout the world. It affects 40 million adults in the US alone and it’s easy for doctors to throw prescription pills at the problem rather than delve deep into what may be responsible for said problem. Rather than get to the root of the cause, they write you a script for Cymbalta and send you off to talk therapy.

But it may surprise you to learn that depression is ordinarily treated with serotoninergic drugs while many afflicted with depression just need a good dopamine boost.

Disorganized Thinking

Dopamine aids us in the organization of our thoughts and enables us to logically sort through them. Many people who are diagnosed with conditions such as disorganized schizophrenia may have dramatically low levels of dopamine.

Low Libido

It may be hard for the dopamine deficient individual to get their mojo working or, in the very least, sustain interest in sex due to their impaired cognitive abilities. With poor concentration and confusion being key factors of low dopamine levels, it’s easy to see why it would be hard to read social cues or concentrate on the act of intercourse.

Other symptoms of dopamine deficiency can include fatigue, lack of motivation, inattentiveness, monotone speech, sleepiness, slow thinking, social awkwardness or withdrawal and weight changes.

How to Know if Your Dopamine Levels Are Low

There are many ways to go about assessing your dopamine levels. One obvious method is to make an appointment to see your primary care physician so that they might run some tests or refer you to a specialist.

For those who prefer to go another route, there are other options as well which we will go into now.
