In this podcast, we separate fact from myth: what are the symptoms, can we reduce our risk, are women more vulnerable to Alzheimer’s, and much more. One of the most striking findings is that around 45% of dementia cases are considered preventable. The choices we make around lifestyle—nutrition, exercise, limiting alcohol, staying mentally and socially engaged, and looking after our hearing and eyesight—can all play a role, according to major dementia and Alzheimer’s organisations. We also address some of the claims circulating on social media about menopause and dementia/Alzheimer’s —for example, the idea that hormone therapy can prevent dementia. Sarah sets the record straight: unfortunately, this isn’t true. She has faced criticism online for challenging this myth, but calling out misinformation is not about women undermining women; it’s about ensuring we share facts rather than perpetuate inaccuracies. That said, research does suggest that frequent hot flushes may be linked to an increased risk. There’s still much more to learn, but what we do know is already powerful. By understanding the evidence on dementia and Alzheimer’s today, we can start taking steps to lower our risk.
