In some cases, dopamine agonists, such as pramipexole (Mirapex®), ropinirole (Requip®) or rotigotine (Neupro®) may be used. Dopamine agonists work by mimicking dopamine, causing nerve cells to react in the same way.
Fluoxetine, but not other selective serotonin uptake inhibitors, increases norepinephrine and dopamine extracellular levels in prefrontal cortex.
Monoamine Oxidase Inhibitors (MAOIs)
MAOIs are a class of antidepressants believed to increase levels of norepinephrine, serotonin, and dopamine (another neurotransmitter) in the brain. They are effective for the treatment of the major depressive disorder, panic disorder, and other anxiety disorders.
Medications. Ropinirole, pramipexole, and levodopa can boost dopamine levels. Levodopa is the precursor to dopamine, which means it is something the body needs to produce dopamine.
An Emory University study published in Nature's Molecular Psychiatry shows levodopa, a drug that increases dopamine in the brain, has potential to reverse the effects of inflammation on brain reward circuitry, ultimately improving symptons of depression.
Levodopa is considered the gold standard for dopamine replacement therapy in Parkinson's disease. The medicine was developed in the 1960s many years after James Parkinson in 1817 wrote about a set of symptoms that today we know as Parkinson's disease.
Norepinephrine and dopamine reuptake inhibitors (NDRIs) are antidepressant medications that block the action of specific transporter proteins, increasing the amount of active norepinephrine and dopamine neurotransmitters throughout the brain.
Sertraline (Zoloft) is a selective serotonin reuptake inhibitor (SSRI), but, uniquely among most antidepressants, it shows relatively high (nanomolar) affinity for the DAT as well. As such, it has been suggested that clinically it may weakly inhibit the reuptake of dopamine, particularly at high dosages.
A person can raise dopamine and serotonin levels with medications such as antidepressants. To naturally boost dopamine and serotonin levels, eat a balanced diet with foods containing tryptophan, the protein that produces these neurotransmitters. Tryptophan-rich foods include: almonds.
Prozac (fluoxetine) and Wellbutrin (bupropion) are examples of “energizing” antidepressants; whereas Paxil (paroxetine) and Celexa (citalopram) tend to be more sedating.
You can increase your dopamine levels naturally by eating a healthy diet, including foods rich in L-Tyrosine (the protein needed to make dopamine). These include almonds, avocados, bananas, beef, chicken and eggs. Turmeric, vitamin D, magnesium and omega-3 supplements are also claimed to increase dopamine levels.
SNRIs achieve faster antidepressant effects than SSRIs by elevating the concentrations of dopamine in the forebrain.
Living With A Dopamine Deficiency
Low dopamine levels are linked to several different mental, physical, and neurodegenerative health conditions, like depression, restless leg syndrome, and Parkinson's disease. People who have lower dopamine levels may also be more susceptible to developing a substance use disorder.
Dopamine deficiency has been linked to neurodegenerative conditions in the body. If you have symptoms of low dopamine levels, you might feel: Anxious or moody. Depressed or hopeless.
Escitalopram (at a dose that affects memory consolidation) increased hippocampal serotonin levels fourfold without changing dopamine or noradrenaline.
How does sertraline work? Sertraline increases serotonin, a potent neurotransmitter, in your brain. With higher levels of serotonin is thought to come feelings of wellbeing and happiness.
One of the widely-reported side effects of SSRIs is 'blunting', where patients report feeling emotionally dull and no longer finding things as pleasurable as they used to. Between 40-60% of patients taking SSRIs are believed to experience this side effect.
Exercise is one of the best ways to increase both dopamine and serotonin. A simple walk, jog, or weightlifting for 30 minutes boosts these chemicals. Studies show that aerobic exercise boosts dopamine and serotonin in specific parts of the brain.
Dopamine receptor blocking agents are known to induce parkinsonism, dystonia, tics, tremor, oculogyric movements, orolingual and other dyskinesias, and akathisia from infancy through the teenage years. Symptoms may occur at any time after treatment onset.
However, magnesium inhibits dopamine release. Therefore, magnesium may inhibit calcium-dependent brain function through dopaminergic neurons, and consequently reduce the effect of calcium on ethanol activity.
Three SNRIs are currently available in Australia: venlafaxine, desvenlafaxine and duloxetine. They are available as tablets or capsules (some as extended or controlled release) and are taken once a day.
What are the signs of a lack of serotonin and dopamine? Deficits in serotonin and dopamine can cause a host of signs and symptoms, including depressed mood, fatigue, lack of motivation, decreased sex drive, and difficulty concentrating.
