In Part 2 of my discussion with neuroscientist Dr Sarah McKay, we kick off by looking at the prevalence of dementia—particularly Alzheimer’s—in Australia, and why women are disproportionately affected.

We also dive into the physiological shifts that occur during perimenopause—specifically the hormonal fluctuations that can affect brain function, sleep, and emotional stability. Dr McKay shares what the latest science says about Hormone Replacement Therapy (HRT): where it helps, where it doesn’t, and how it fits into the broader picture of women’s brain health.
