Neurotransmitter Profile Test

The extensive Neurotransmitter Profile Test is a urine test, assessing levels of 6 neurotransmitters (“Brain Chemicals”: serotonin, GABA, dopamine, noradrenaline, adrenaline, and glutamate. These 6 neurotransmitters are the most researched in relation to their effects on mood disorders, hormones, sleep, glucose/insulin balance, pain perception, appetite, and cognitive function.

Low or high levels of neurotransmitters are observed in various mental health disorders, such as depression, attention-deficit hyperactivity disorder (ADHD), Parkinson’s disease and panic attacks.

Serotonin plays an important role as a neurotransmitter in the regulation of anger, appetite, body temperature, mood, sexuality and sleep. Low levels may be associated with aggression, anxiety, depression, eating disorders, impulsivity, irritability and sleep disorders.

Dopamine is involved in the regulation of pleasure and reward, memory, motor control, sleep, mood, attention and learning. Lowered dopamine has been associated with loss of satisfaction, social withdrawal, apathy, reduced motivation and attention. In addition, low dopamine levels can result in impaired motor control, e.g. Parkinson’s disease. High levels of dopamine may result in aggression, Schizophrenia, hyperactivity and Tourette’s syndrome.

Noradrenaline (norepinephrine) and adrenaline (epinephrine) are excitatory neurotransmitters as well as hormones. They are most well known for their involvement in the ‘fight and flight’ response, in which they increase heart rate, trigger the release of glucose from energy stores and increase blood flow to skeletal muscle. Low levels contribute to a decrease in mood, energy, focus, motivation and memory. High levels are associated with aggression, anxiety, emotional lability, hyperactivity, mania, stress and suppression of the immune system.

GABA (gamma-aminobutyric acid) is concentrated in the hypothalamus region of the brain and is known to play a role in the overall functioning of the pituitary gland – which regulates growth hormone synthesis, sleep cycles, and body temperature.

Glutamate is involved in most aspects of normal brain function including cognition, memory and learning.

The Extensive Neurotransmitter Profile test is available at the Graceville and Brisbane CBD Naturopath and Nutritionist clinic.
