What is the Origin of Estrogen and Mood?

This concept is rooted in clinical endocrinology and neuroendocrinology, gaining prominence through observations of mood changes correlating with hormonal shifts throughout the female lifespan. The term connects the specific steroid hormone 'estrogen' with the psychological domain of 'mood,' emphasizing their physiological interdependency. Research in the late 20th and early 21st centuries solidified the neural mechanisms underlying this connection.

What is the Mechanism of Estrogen and Mood?

Estrogen readily crosses the blood-brain barrier and binds to estrogen receptors (ERα and ERβ) expressed in mood-regulating areas like the hippocampus and prefrontal cortex. It influences the synthesis, release, and reuptake of neurotransmitters, notably serotonin, dopamine, and norepinephrine, and promotes neuronal survival and plasticity. This direct neuroendocrine signaling pathway underpins the hormonal influence on emotional resilience.

Estrogen and Mood

Meaning

Estrogen and Mood describes the well-established, bidirectional relationship between circulating estrogen levels, particularly estradiol, and the regulation of emotional state, cognitive function, and psychological well-being in women. Estrogen exerts significant modulatory effects on key neurotransmitter systems and brain regions associated with mood stability, anxiety, and depression. Fluctuations or deficiencies in this hormone are clinically linked to mood lability across the menstrual cycle, perimenopause, and menopause.
