NEUROTRANSMITTERS PLAY A KEY ROLE 
Neurotransmitters play a key role in facilitating communication between nerve cells (neurons) in the brain and throughout the nervous system. Here are some key roles of neurotransmitters:

  • Regulation of Mood and Emotions: Neurotransmitters such as serotonin, dopamine, and norepinephrine are involved in regulating mood, emotions, and feelings of pleasure and reward. Imbalances in these neurotransmitters have been associated with mood disorders like anxiety, depression and bipolar disorder.
  • Control of Motor Functions: Neurotransmitters like acetylcholine, dopamine, and gamma-aminobutyric acid (GABA) play a crucial role in controlling and coordinating motor functions. They help regulate muscle movements, balance, and coordination.
  • Cognitive Function and Learning: Neurotransmitters like glutamate, acetylcholine, and dopamine contribute to cognitive function, learning, and memory. They facilitate the transmission of signals in brain regions responsible for cognition, attention, and information processing.
  • Regulation of Sleep and Wakefulness: Neurotransmitters such as serotonin and norepinephrine help regulate sleep and wakefulness cycles. They influence the timing and quality of sleep, as well as the transition between different sleep stages.
  • Modulation of Pain Perception: Certain neurotransmitters, such as endorphins and enkephalins, are involved in the modulation of pain perception. They can inhibit or dampen the transmission of pain signals, resulting in pain relief.
  • Autonomic Functions: Neurotransmitters regulate various autonomic functions, including heart rate, blood pressure, digestion, and respiration. Neurotransmitters like acetylcholine and norepinephrine are particularly involved in the autonomic nervous system's control over these functions.
  • Regulation of Appetite and Satiety: Neurotransmitters such as serotonin and neuropeptide are involved in the regulation of appetite, satiety, and food intake. Imbalances in these neurotransmitters can contribute to eating disorders and weight management issues.

Overall, neurotransmitters play a vital role in numerous physiological and psychological processes, maintaining the proper functioning of the nervous system and influencing various aspects of human behaviour and experience.

ARE YOU AFFECTED?

Imbalances in neurotransmitters can have significant effects on mental and physical health. Here are some potential outcomes of neurotransmitter imbalances:

  • Mood Disorders: Alterations in neurotransmitter levels, particularly serotonin, dopamine, and norepinephrine, are associated with mood disorders such as depression, bipolar disorder, and anxiety disorders. Low levels of serotonin, for example, have been linked to depressive symptoms, while imbalances in dopamine can contribute to mood swings and instability.
  • Cognitive Impairment: Disruptions in neurotransmitter balance can impact cognitive function, memory, attention, and information processing. For instance, deficiencies in acetylcholine have been associated with memory impairment and cognitive decline seen in conditions like Alzheimer's disease.
  • Sleep Disturbances: Imbalances in neurotransmitters can affect the regulation of sleep-wake cycles. Insufficient serotonin or disruptions in the balance of other neurotransmitters can lead to sleep disorders, such as insomnia or excessive sleepiness.
  • Neurological Disorders: Neurotransmitter imbalances have been implicated in various neurological conditions. For example, disruptions in dopamine function are associated with Parkinson's disease, a disorder characterized by motor symptoms, while abnormalities in glutamate and GABA transmission are implicated in epilepsy and seizures.
  • Impaired Motor Function: Imbalances in neurotransmitters involved in motor control, such as dopamine, can lead to motor abnormalities. Parkinson's disease, for instance, is characterized by a deficiency of dopamine, resulting in movement difficulties, tremors, and muscle rigidity.
  • Addiction and Substance Abuse: Neurotransmitter imbalances, particularly involving dopamine, play a significant role in addiction and substance abuse. Substance use can alter neurotransmitter levels and affect reward pathways in the brain, leading to dependence and addiction.
  • Hormonal Imbalances: Neurotransmitters can influence the release and regulation of hormones in the body. Imbalances in neurotransmitters may disrupt the normal functioning of the endocrine system, affecting hormone production, metabolism, and various physiological processes.
  • Digestive Disorders: Neurotransmitter imbalances, such as disruptions in serotonin levels, can impact the digestive system. Low serotonin levels have been associated with gastrointestinal issues like irritable bowel syndrome (IBS) and other functional gastrointestinal disorders.

Neurotransmitters & Your Health

  • Do you suffer from anxiety or depression?

Anxiety and Depression: Imbalances in neurotransmitters such as serotonin, norepinephrine, and dopamine have been associated with anxiety and depression. Low levels of serotonin, in particular, have been linked to feelings of anxiety and low mood, while imbalances in dopamine and norepinephrine can also contribute to these conditions.

  • Do you struggle to fall asleep or stay asleep throughout the night? 

Sleep Disorders: Neurotransmitters play a role in regulating sleep-wake cycles. Imbalances in neurotransmitters like serotonin and melatonin can disrupt the sleep process, leading to difficulties falling asleep, staying asleep, or experiencing restful sleep. For example, low serotonin levels can contribute to insomnia, while disturbances in melatonin can affect the timing of sleep.

  •  Has your libido fizzled?

Libido: Neurotransmitters influence sexual desire and function. Dopamine, in particular, plays a role in the brain's reward and pleasure pathways, including sexual pleasure. Imbalances in dopamine or other neurotransmitters can contribute to a decrease in libido or sexual dysfunction.

  • Women, do you dread the weeks before your period?

Premenstrual Symptoms: Changes in neurotransmitter levels, such as fluctuations in serotonin and gamma-aminobutyric acid (GABA), can contribute to premenstrual symptoms in women. Low serotonin levels, in particular, have been linked to mood swings, irritability, and other emotional symptoms experienced before menstruation.

If you answered yes to these questions, an underlying neurotransmitter imbalance might be the cause. Simple testing may help you find personalised solutions.

Neurotransmitters & Their Impact
Neurotransmitters are chemical messengers used by the nervous system to relay information from one nerve to another. The body relays information through the nervous system about anything that it experiences, hears, touches, smells, or ingests – continuously communicating back and forth between the brain and the body.

Neurotransmitters play a crucial role in relaying information and maintaining proper health. Here are some key points about neurotransmitters and their impact:

  • Communication: Neurotransmitters facilitate communication between nerve cells (neurons) in the brain and throughout the nervous system. They transmit signals across synapses, the small gaps between neurons, allowing information to be relayed and processed.
  • Neurological Function: Neurotransmitters regulate various neurological functions, including sensory perception, motor control, cognition, and emotions. They contribute to the overall functioning and coordination of the nervous system.
  • Psychological Function: Imbalances in neurotransmitters can affect psychological well-being and mental health. For example, serotonin is involved in regulating mood, sleep, and appetite, while dopamine plays a role in motivation, reward, and pleasure. Imbalances in these neurotransmitters and others can contribute to conditions such as depression, anxiety, bipolar disorder, and schizophrenia.
  • Neurotransmitter Imbalances: When neurotransmitters are not in proper balance, it can lead to neurological or psychological symptoms. For example, low levels of serotonin may be associated with depressive symptoms, while excessive dopamine activity may contribute to psychosis or mania. Imbalances can result from genetic factors, environmental influences, lifestyle choices, and underlying medical conditions.
  • Impact on Physical Health: Neurotransmitters also influence physical health beyond the nervous system. For instance, neurotransmitters such as norepinephrine and acetylcholine play a role in regulating heart rate, blood pressure, digestion, and other autonomic functions.
  • Treatment Approaches: Understanding neurotransmitter imbalances can help guide treatment approaches. Medications targeting specific neurotransmitter systems (e.g., selective serotonin reuptake inhibitors for depression) aim to restore balance and alleviate symptoms. Lifestyle changes, therapy, and other interventions may also be recommended to support optimal neurotransmitter function.

Optimal neurotransmitter balance is required to maintain proper health. Imbalances can cause the brain and the body to be over- or understimulated, producing neurological or psychological symptoms.

Can a Dysregulated Nervous System Impact Health?
Like hormones, neurotransmitters require a delicate balance to keep the body functioning at a peak level.

Genetics, environment, chemicals, and nutritional deficiencies are a few factors that can result in the over- or under-production of neurotransmitters. Once out of balance, the nervous system begins to compensate – which, in time, can lead to neurological or psychological symptoms.

Some of the more common psychological conditions today are known to be accompanied by neurotransmitter imbalances. However, it’s also possible for individuals to present with similar symptoms yet have unique foundational imbalances. Testing helps clarify these root issues.

Saliva testing measures hormones like cortisol, estrogen, progesterone, DHEA and testosterone. Its non-invasive collection asks patients to spit into a plastic tube. This sampling method allows patients to collect saliva at home at specific times, which is vital for measuring hormone levels accurately.

Neurotransmitters and Children
Neurotransmitter imbalances can also impact children and their overall well-being. Here are some points regarding the effects of neurotransmitter imbalances on children:

  • Behavioural and Emotional Issues: Imbalances in neurotransmitters can contribute to behavioural and emotional issues in children. For example, low levels of serotonin have been associated with anxiety, depression, and mood disorders in children. Imbalances in dopamine may contribute to attention deficit hyperactivity disorder (ADHD) or impulsive behaviour.
  • Learning and Cognitive Difficulties: Neurotransmitter imbalances can affect learning and cognitive function in children. For instance, imbalances in acetylcholine and glutamate may impact memory, attention, and information processing, which can affect academic performance and cognitive development.
  • Sleep Disturbances: Disruptions in neurotransmitter balance can lead to sleep disturbances in children. Imbalances in serotonin and melatonin, which regulate sleep-wake cycles, can result in difficulties falling asleep, staying asleep, or experiencing restful sleep.
  • Developmental Disorders: Neurotransmitter imbalances have been implicated in various developmental disorders, such as autism spectrum disorder (ASD). Imbalances in neurotransmitters like serotonin, dopamine, and gamma-aminobutyric acid (GABA) have been associated with ASD symptoms, including social communication difficulties and repetitive behaviours.
  • Sensory Processing Issues: Neurotransmitter imbalances can contribute to sensory processing issues in children. Disruptions in neurotransmitter systems involved in sensory integration, such as serotonin and dopamine, can affect how children process and respond to sensory stimuli, leading to sensory sensitivities or sensory-seeking behaviours.
  • Treatment Considerations: Addressing neurotransmitter imbalances in children often involves a multifaceted approach. Depending on the specific imbalance and symptoms, interventions may include medication, behavioural therapies, dietary changes, and lifestyle modifications. Working with healthcare professionals, such as paediatricians, psychiatrists, or developmental specialists, can help determine appropriate treatment strategies.

It's important to note that children's neurotransmitter imbalances can be influenced by a variety of factors, including genetic predisposition, prenatal and early life experiences, environmental influences, and comorbid conditions. Professional evaluation and individualised treatment planning are crucial for identifying and addressing neurotransmitter imbalances in children.

Neurotransmitters You Should Know
There are many neurotransmitters in the body. The primary messengers are divided into two groups.

Excitatory:

  • Dopamine, generally regarded as the brain’s pleasure and reward centre, plays the central role in addiction, improves attention, focus and motivation, and modulates movement control.
  • Epinephrine and Norepinephrine regulate the “fight or flight” response, elevate blood pressure and heart rate, stimulate wakefulness and reduce digestive activity.
  • Glutamate functions as the “on” switch in the brain. It’s the major excitatory neurotransmitter that decreases sleep, optimizes learning, memory, and mood, and improves libido.
  • Histamine plays a role in the body as a neurotransmitter that increases metabolism, promotes wakefulness, and suppresses appetite.
  • PEA (phenylethylamine) promotes energy, elevates mood, regulates attention aggression and serves as a biomarker for ADHD.

Inhibitory:

  • GABA functions as the “off” switch in the brain. It’s the major inhibitory neurotransmitter that improves mood, relieves anxiety, and promotes sleep.
  • Glycine plays a dual role as a neurotransmitter and amino acid that serves as a building block to proteins, improves sleep quality, calms aggression, and serves as an anti-inflammatory agent.
  • Serotonin, generally regarded as the “happiness molecule,” contributes to the feeling of calm and well-being that eases depression and anxiety, supports sleep and decreases appetite.

Neurotransmitter Imbalance & Chronic Conditions
Numerous neurotransmitter imbalances may cause persistent health concerns:

  • Anxiety & Depression: Imbalances are often associated with Glutamate (panic attacks), PEA, Histamine, Serotonin, as well as Epinephrine and Norepinephrine.
  • Fatigue: An imbalance between excitatory and inhibitory neurotransmitters is likely.
  • Impulsivity: GABA, Dopamine, and Serotonin are three chemical messengers commonly linked to disorders like ADD, ADHD, and OCD.
  • Insomnia: Glutamate, Histamine, Dopamine, GABA, and Serotonin are several chemical messengers often linked to sleep disturbances and insomnia.
  • PMS or PMDD: Imbalances such as Serotonin, Dopamine, Norepinephrine, and GABA are often involved

Neurotransmitter Testing – Giving a Diagnostic Edge in Treating Mood Disorders.

Mental health disorders affect millions of people and profoundly contribute to the burden of disease in society. 

The current treatment paradigm in addressing poor brain health relies on diagnostic tools that encompass the evaluation of clinical signs and symptoms. Despite the lack of testable biomarkers for mood disorders, for many patients, treatments can generally be effective. However, even after treatment, frequent relapse episodes can still occur. Furthermore, a large number of patients suffer from treatment-resistant depression. Therefore, the selection of the best therapeutic regimen for each patient remains a challenge and is often discovered through a time-consuming process of trial and error. Also, no single approach works for everyone with any one disorder.

Targeted neurotransmitter testing can help healthcare practitioners achieve a diagnostic edge beyond the traditional psychological inventory by identifying specific imbalances in neurotransmitter levels. Based on neurotransmitter test results, practitioners can identify specific biochemical heterogeneities for each particular patient and objectively monitor therapeutic responses during and after the intervention. Neurotransmitter testing objectively enhances medical assessment and represents a major advance in the personalization of the treatment of mood disorders.

How Neurotransmitters Relay Information within the Body

The brain orchestrates the delicate interplay between the body and the mind. Structural brain units, the neurons, discharge neurotransmitters. These neurotransmitters provide a communication platform for the brain to fuel internal systems with information. Anything the body senses, feels, hears, smells, touches, or ingests serves as an input that prompts an astoundingly fast response. In the central and peripheral nervous system, neurotransmitters operate as chemical messengers that relay the signal and receive feedback via electrochemical impulses to regulate cognition, memory, emotions, respiration, heart rate and contractility, digestion, metabolism, blood flow and pressure, and hormonal responses. When released from peripheral organs, neurotransmitters can also behave as hormones by diffusing to distant sites via circulation.

The Benefit of Testing Saliva Hormone Tests with Neurotransmitters Test

The combined testing of saliva hormone levels, including Estradiol, Progesterone, Testosterone, DHEAS (DS), and Cortisol, with neurotransmitters provides several benefits in assessing and managing overall hormonal and neuroendocrine health. Here are the potential benefits of this comprehensive testing approach:

  • Hormonal Balance Assessment: Saliva hormone testing allows for a precise evaluation of hormone levels, including Estradiol, Progesterone, Testosterone, and DHEAS. This assessment helps identify hormonal imbalances that may be contributing to various symptoms and conditions, such as menstrual irregularities, infertility, mood swings, low libido, and fatigue.
  • Neuroendocrine Function Evaluation: Neurotransmitters play a crucial role in regulating mood, behaviour, and cognitive function. By combining saliva hormone testing with neurotransmitter analysis, a comprehensive assessment of the neuroendocrine system is achieved. This provides insights into the interplay between hormones and neurotransmitters, offering a more complete understanding of the factors influencing mental and emotional well-being.
  • Stress Response Assessment: Cortisol, a stress hormone, affects multiple body systems and plays a role in managing stress. Measuring cortisol levels alongside neurotransmitter and hormone testing provides insights into the body's stress response and its impact on neuroendocrine balance. This information helps identify adrenal dysfunction, chronic stress, and its potential effects on mental and physical health.
  • Personalized Treatment Approach: The integration of saliva hormone testing with neurotransmitter analysis enables healthcare providers to develop personalized treatment plans. This comprehensive approach allows for targeted interventions, including hormone replacement therapy, nutritional support, stress management techniques, and lifestyle modifications tailored to address specific imbalances.
  • Improved Symptom Management: By identifying and addressing hormone imbalances and neurotransmitter irregularities, this combined testing approach helps in managing symptoms associated with hormonal and neuroendocrine disorders. It provides valuable insights for optimizing hormone levels and supporting overall well-being.
  • Optimized Neuroendocrine Health: The comprehensive evaluation of both hormone levels and neurotransmitters supports the optimization of neuroendocrine health. It allows for a more thorough understanding of the underlying factors contributing to symptoms, offering an opportunity for targeted interventions and improved overall health outcomes.

By combining saliva hormone testing for Estradiol, Progesterone, Testosterone, DHEAS (DS), and Cortisol with neurotransmitter analysis, a comprehensive assessment of hormonal and neuroendocrine health is achieved. This approach provides valuable insights into imbalances, stress response, and the interplay between hormones and neurotransmitters. Working with qualified healthcare professionals is essential to accurately interpret test results and develop tailored treatment plans that address individual needs and support optimal health and well-being.

Clinical Utility of Urinary Neurotransmitter Analysis

The aetiology of mood disorders is profoundly complex and likely encompasses many different types of neurotransmitters, how they achieve balance in the brain and in the gut axis, and how they each interplay with other hormone systems throughout the body. Appropriate balancing of neurotransmitter signals allows the body to maintain equilibrium. When brain and peripheral neurochemistry become unbalanced, the body will struggle to re-establish physiological integrity, which may present in the form of suboptimal psychological well-being. Excessive or deficient levels of certain neurotransmitters in both the brain and the periphery are associated with a spectrum of neurobiological disorders, such as depression and anxiety. The measurement of specific imbalances may be a very effective neurobiological tool in guiding targeted intervention aimed at addressing the individual excess or deficiency in question.

Clinical Validity of Urinary Neurotransmitter Assessment

The importance of effectively assessing and treating mood disorders cannot be overstated. Objectivity is a key element of the therapeutic approach to mood disorders. Currently, the standard of care dictates a trial-and-error pharmaceutical approach is taken with each patient based on both self and clinician assessments. However, without information yielded from objective clinical testing, the selection of the most effective treatment for each particular patient with a mood disorder continues to be a challenge. While this may prove effective for some patients, the potential for harm during those interim treatment failures is a real concern for clinicians and patients alike. Urinary neurotransmitter testing is performed with the goal that therapeutic interventions may be introduced to address, alleviate, and improve a patient’s well-being and have a breadth of data to support the efficacy of the test in clinical practice. Evaluation of neurotransmitter levels in urine provides valuable information about the heterogeneity of patient biochemistry, epigenetics, and how the body functions as a whole. Although the urine test is not a direct measure of brain neurotransmitter levels, it provides relevant information with respect to neurotransmitter regulation in the brain, which can be altered by treatment. The levels in urine often parallel levels in the central nervous system, and the test may therefore assist in the selection of patients with mood issues who might respond to specific pharmaceutical or over-the-counter treatment interventions. In other words, the test provides a means to glean a functional systemic perspective regarding each neurotransmitter in the periphery, which ultimately operates under the control of the brain. How do neurotransmitters end up in urine? Some neurotransmitters are produced in the brain and transported across the blood-brain barrier into the blood, and others are produced in the periphery (e.g., norepinephrine and epinephrine). Nephrons, the functional units of the kidney, filter circulating neurotransmitters or their precursors from the blood into the urine. For some neurotransmitters, urinary measurements correlate with levels in the central nervous system (e.g., glutamate, PEA), and for others, what ends up in urine is only reflective of peripheral biosynthesis (e.g., serotonin, GABA, dopamine, norepinephrine, epinephrine). Regardless of production origin, neurotransmitter excretion reflects the overall systemic neurotransmitter tone, the dysregulation of which may contribute to disease states. The ability to identify abnormality across specific areas of the catecholamine and PEA, GABA/ glutamate, serotonin, histamine, and glycine pathways allows healthcare providers to develop a tailored treatment plan for the specific areas associated with imbalance. 

Dried Urine – A Convenient Testing Option

The nature of urine collection is non-invasive and preferable over the traditional invasive collection approaches, such as the measurement of cerebrospinal fluid. Even with liquid urine collection, the patient experiences the enormous hassle of collecting all urine voids over a 24-hour period into a large jug. To circumvent this inconvenience, some labs have settled for collecting only the 2nd void, limiting neurotransmitter results to a single morning time point snapshot. ZRT Laboratory offers an alternative to the liquid urine collection method by offering a simple and convenient collection of four separate urine samples at specific time points throughout the day – 1st morning, 2nd morning (approximately 2 hours after the first collection), early evening, and bedtime. Urine is collected onto filter strips by urinating directly on the strip or by dipping the filter card in a cup containing the collected urine. The urine cards are then allowed to dry overnight and sent to ZRT for testing. The convenience of the collection method warrants patient compliance and ease of incorporation into clinical practice.

Considerations 

  • The neurotransmitter test assumes proper kidney function. Neurotransmitter levels are reported in µg/g creatinine, where creatinine is measured from the same sample. This test should not be used in individuals with compromised renal function. 
  • The sample can become very dilute due to increased fluid consumption during the day. Therefore, on the day of testing, individuals should restrict their liquid intake to normal consumption.
  • On the day of testing, individuals are advised to refrain from consuming alcohol, nicotine, bananas, pineapple, and walnuts as they may interfere with testing.
