Estrogen Balance CNS

Meaning

Estrogen Balance CNS refers to the precise, dynamic equilibrium of estrogenic hormones and their metabolites within the central nervous system (CNS), a state essential for optimal cognitive function, mood regulation, and neuronal health. This balance is not about a single absolute estrogen level but the ratio of different estrogen forms (e.g., estradiol, estrone) and their modulated activity at various estrogen receptor subtypes (ERα, ERβ) in the brain. Maintaining this delicate neuroendocrine homeostasis is crucial for supporting synaptic plasticity, cerebral blood flow, and protecting against neurodegeneration, especially across the lifespan.
