After making it through perimenopause and menopause, people's mood and cognition tend to stabilise — yet oestrogen levels remain low. Why is this? For the most part, our brain will adjust to lower oestrogen levels, and many symptoms will ease. But for some women, this new normal might make them more vulnerable to neurodegenerative conditions. For instance, two-thirds of Australians with dementia are women. No-one knows for sure why that is, but one theory points the finger at oestrogen. One of oestradiol's benefits is it has a protective effect on the brain, so take it away and you might increase brain inflammation — something that's implicated in conditions such as Alzheimer's disease, Dr Gurvich says. "But this is more of a hypothesis at the moment, and an area that's really just starting to be uncovered."
