What is the Origin of Hormonal Mood Regulation?

This is a core concept within the field of neuroendocrinology, which studies the intricate connection between the systemic endocrine glands and the central nervous system. The term "hormone" comes from the Greek hormao, meaning I excite or set in motion.

What is the Mechanism of Hormonal Mood Regulation?

Hormones exert their influence by crossing the blood-brain barrier and interacting with specific receptors on neurons and glial cells in limbic structures such as the hippocampus and amygdala. Estrogen, for instance, can enhance the sensitivity of serotonin and dopamine receptors, which are crucial for feelings of well-being and reward. Conversely, chronic or dysregulated cortisol elevation can impair neurogenesis and cause atrophy in the hippocampus, a mechanism strongly implicated in the pathophysiology of major depression and anxiety disorders.

Hormonal Mood Regulation

Meaning

Hormonal Mood Regulation describes the complex, integrated neuroendocrine process through which circulating hormones modulate the structure, functional connectivity, and neurotransmitter balance within the brain regions that govern emotional state, affect, and cognitive stability. Significant fluctuations in key endocrine messengers, particularly sex steroids, thyroid hormones, and glucocorticoids, are powerful determinants of mood stability and can confer vulnerability to various affective disorders.
