The Neurotransmitter Questionnaire is a 237-item true/false checklist of symptoms and temperament traits organized around four brain chemicals: dopamine, acetylcholine, GABA and serotonin. It separates your natural temperament (nature) from possible signs of depletion (deficiency). It comes from an integrative-health framework, so treat it as a conversation starter, not a medical or laboratory test. About 25 minutes.
