Neurotransmitter Testing

Can your brain talk to your body? Let’s check.

Neurotransmitters (N.T.’s) are the chemical messengers that our brain uses to communicate with our body. They’re responsible for our mood, sleep, concentration, weight, and more. Occasionally, our neurotransmitter levels get out of whack, and our body experiences some familiar, but unwelcome symptoms. Luckily, we’re able to test which of your brain chemicals are high, low, and just right. Providing chemical balance to your brain can have an outstanding effect on your health.

Below is an overview of six important neurotransmitters and their respective roles in various symptomatic conditions. Refer to the neurotransmitter test menu for panel options.

See a sample Neurotransmitter test here.

Serotonin

Serotonin is a key neurotransmitter that is involved in the regulation of sleep, appetite and aggression. Serotonin imbalance is a common contributor to mood problems, and pharmacologic agents that alter serotonin levels are among the most commonly used class of drugs prescribed for anxiety and depression.

High stress, insufficient nutrients, fluctuating hormones and the use of stimulant medications or caffeine can all contribute to the depletion of serotonin over time. When serotonin is out of range, depression, anxiety, worry, obsessive thoughts and behaviors, carbohydrate cravings, PMS, difficulty with pain control, and sleep cycle disturbances can result.

Gaba

Gaba is the major inhibitory neurotransmitter found in the Central Nervous System. It is important for balancing excitatory action of other neurotransmitters. High levels of Gaba may be a result of excitatory overload, or a compensatory mechanism to balance the surplus excitatory neurotransmitter activity. These high levels result in a ‘calming’ action that may contribute to sluggish energy, feelings of sedation, and foggy thinking. Low Gaba levels are associated with dysregulation of the adrenal stress response. Without the inhibiting function of Gaba, impulsive behaviors are often poorly controlled, contributing to a range of anxious and/or reactive symptoms that extend from poor impulse control to seizure disorders. Alcohol as well as benzodiazepine drugs act on Gaba receptors and imitate the effects of Gaba. Though these substances don’t cause an increase in Gaba levels, understanding their mechanism can give us additional insight into the effects of Gaba.

DOPAMINE

Dopamine is largely responsible for regulating the pleasure reward pathway, memory and motor control. Its function creates both inhibitory and excitatory action depending on the dopaminergic receptor it binds to. Memory issues are common with both elevations and depressions in dopamine levels. Caffeine and other stimulants, such as medications for ADD/ADHD, often improve focus by increasing dopamine release, although continual stimulation of this release can deplete dopamine over time.

Common symptoms associated with low dopamine levels include loss of motor control, cravings, compulsions, loss of satisfaction and addictive behaviors including: drug and alcohol use, smoking cigarettes, gambling, and overeating. These actions often result from an unconscious attempt to self-medicate, looking for the satisfaction that is not occurring naturally in the body.

Elevated dopamine levels may contribute to hyperactivity or anxiety and have been observed in patients with schizophrenia. High dopamine may also be related to autism, mood swings, psychosis and attention disorders. L-DOPA is a precursor to dopamine, and is used therapeutically for low dopamine conditions such as Parkinson’s disease. These medications can cause elevations in dopamine.

Norepinephrine

Norepinephrine, also called noradrenaline, is an excitatory neurotransmitter produced in the Central Nervous System, as well as a stress hormone produced in the adrenal medulla. Norepinephrine is involved in a wide variety of actions including attention, focus, regulating heart rate, affecting blood flow, and suppressing inflammation. Involved in arousal, it prepares the body for action by relaying messages in the sympathetic nervous system as part of the autonomic nervous system’s fight-or-flight response. High levels of norepinephrine are often linked to anxiety, stress, elevated blood pressure, and hyperactivity, whereas low levels are associated with lack of energy, focus, and motivation.

Epinephrine

Epinephrine, often better known as adrenaline, is synthesized from norepinephrine in both the Central Nervous System and the adrenal medulla. Much like norepinephrine, this excitatory neurotransmitter helps regulate muscle contraction, heart rate, glycogen breakdown, blood pressure and more, and is heavily involved in a stress response. Elevated levels of epinephrine are often associated with hyperactivity, ADHD, anxiety, sleep issues, and low adrenal function. Over time, chronic stress and stimulation can deplete epinephrine stores leading to difficulty concentrating, fatigue, depression, insufficient cortisol production, chronic stress, poor recovery from illness, dizziness and more.

Glutamate

Glutamate is an excitatory neurotransmitter and is considered to be the most abundant neurotransmitter in the nervous system. Glutamate is involved in most aspects of normal brain function including cognition, memory and learning, although high levels of glutamate can cause excitotoxicity, a process where nerve cells are damaged by excessive stimulation. Elevated glutamate levels are commonly associated with panic attacks, anxiety, difficulty concentrating, OCD and depression, whereas low glutamate levels may result in agitation, memory loss, sleeplessness, low energy levels and depression.

Unfortunately, Neurotransmitter testing is not covered by insurance. We do not mark-up lab testing offered from our clinic, our price is the price you pay. We offer this testing to determine chemical imbalances that can be identified and resolved with neurotransmitter balancing. We do charge exam and consultation fees for our time analyzing these results. NT testing ranges from $45 per individual chemical to $450 for a complete NT + Adrenal + hormone panel.  Lab panel options will be discussed at your appointment.
