Hormone Health Hub: Expert Insights on Testing, Balance & Better Living — perimenopause and mood swings

Perimenopause is far more than a collection of symptoms to manage — it is a critical window of opportunity to protect long-term cardiovascular, skeletal, and cognitive health. The hormonal fluctuations of this transition are directly linked to cardiovascular risk, making proactive action during perimenopause one of the most important investments a woman can make in her future health. This article outlines a practical three-step perimenopausal game plan covering hormone replacement, resistance training, and time-restricted eating — grounded in current research and designed to build the physiological reserves needed for a healthy postmenopause.

Hot flashes, mood instability, brain fog and memory changes during perimenopause are not “all in your head” — but they are very much in your brain. In this in-depth clinical article, Dr. Kate Placzek of ZRT Laboratory explains how declining estradiol disrupts brain glucose metabolism, neurotransmitter signalling and thermoregulation, why perimenopause represents a window of neurological vulnerability, and why the timing of hormone replacement therapy is critical to protecting long-term brain health.
