The nervous system DNA test examines the key genes and variants (SNPs) that affect neurotransmitter balance, nerve cell growth & maintenance,  thyroid hormone conversion, inflammation and pharmacological response.

Common genetic variants combined with environmental factors including nutrient imbalances, low physical activity, toxins and other stressors can result in anxiety, depression, mood imbalances, lack of motivation, drive or focus, addiction, poor memory or sleep disturbances.

This report focuses on the key genes and variants (SNPs) involved in the neurotransmitter pathways: serotonin-melatonin, dopamine-noradrenaline-adrenaline, and GABA-glutamate; neuropharmacology (drug metabolism); and neuroprotection, inflammation (kynurenine-pathway), thyroid function and stress response.
