Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — affect regulation

Perimenopause is far more than a reproductive transition — it is fundamentally neurological. As oestradiol declines, the brain’s bioenergetic system becomes compromised, neurotransmitter balance shifts, and the thermoneutral zone narrows, giving rise to hot flashes, mood instability, memory changes and sleep disruption. This article explores the neuroscience behind the menopausal transition and why hormone replacement therapy — timed correctly — may be the most effective intervention.

Explore the powerful connection between hormones, neurotransmitters, and mood in PMS and PMDD. Learn how progesterone, allopregnanolone, GABA, serotonin, cortisol, and estrogen fluctuations throughout the menstrual cycle may contribute to anxiety, irritability, depression, fatigue, sleep disturbances, and severe premenstrual symptoms. Discover how hormone and neurotransmitter testing can help identify underlying imbalances linked to menstrual mood disorders.
