The midlife brain and estrogen's role

In this episode of SHE MD, Mary Alice Haney and Dr. Thaïs Aliabadi welcome back Dr. Kelly Casperson to discuss perimenopause, menopause, and hormone therapy with clarity and science instead of fear.

Dr. Casperson explains why perimenopause is a clinical diagnosis, not simply a lab result, and why so many women are dismissed as “too young” or “too old” when their symptoms are real. She addresses the biggest myth about hormone replacement therapy and reframes the conversation around individualized, science-backed risk-benefit decisions.

The discussion dives into testosterone for women, including its impact on libido, motivation, muscle mass, and mood, along with the risks of high-dose hormone pellets. They explore progesterone for sleep, the hysterectomy myth, and why vaginal estrogen is one of the safest and most effective treatments for dryness, painful sex, bladder urgency, and recurrent UTIs.

The episode also tackles the midlife brain, brain fog, and how estrogen influences glucose metabolism. From restoring desire in long-term relationships to navigating alcohol, supplements, and exercise, this conversation reinforces one powerful truth: women are not broken. With the right knowledge and support, midlife can be a season of clarity, strength, and transformation.
