What is the Origin of Hormonally Mediated Mood Disorders?

The concept is ancient, but its clinical formalization has advanced significantly with modern endocrinology, allowing for precise measurement and attribution of mood symptoms to specific hormonal fluctuations. It recognizes the brain as a major target organ for all circulating hormones, fundamentally linking endocrinology directly to the field of psychiatry.

What is the Mechanism of Hormonally Mediated Mood Disorders?

Hormones exert powerful control over mood by modulating the synthesis, release, and receptor sensitivity of key neurotransmitters, including serotonin, dopamine, and GABA, in limbic structures. For example, the volatile fluctuations in estrogen and progesterone can alter GABAergic transmission, directly impacting anxiety and emotional stability, while thyroid hormones are essential cofactors for robust catecholamine metabolism.

Hormonally Mediated Mood Disorders

Meaning

A category of affective and emotional dysregulation characterized by a primary etiology rooted in a significant imbalance, deficiency, or dysregulation of endocrine hormones, as opposed to purely psychological or primary neurological causes. This includes conditions like Premenstrual Dysphoric Disorder (PMDD), postpartum depression, and mood changes secondary to thyroid dysfunction or hypogonadism. It necessitates an endocrine-first diagnostic and therapeutic approach for effective resolution.
