The clinical process of assessing and adjusting the relative concentrations and signaling efficiency of key central nervous system (CNS) signaling molecules, including serotonin, dopamine, GABA, and acetylcholine, to support mood, cognition, and overall neuroendocrine health. Tuning aims for optimal receptor engagement rather than simply normalizing precursor levels. This balance profoundly affects stress resilience.
Origin
This practice merges clinical psychiatry, neurochemistry, and endocrinology, recognizing the bidirectional communication between the brain and the endocrine glands. Neurotransmitters act as crucial messengers that influence the release of GnRH, CRH, and TRH from the hypothalamus. Tuning implies fine-adjustment within a dynamic equilibrium.
Mechanism
The tuning mechanism involves detailed evaluation of metabolite profiles to infer CNS activity, followed by targeted nutritional support or targeted neuromodulators that influence reuptake or receptor sensitivity. For instance, optimizing B-vitamin status supports the enzymatic synthesis of catecholamines, thereby stabilizing mood and reducing HPA axis hyperactivity. Proper tuning ensures clear communication across the entire neuroendocrine axis.
