It’s a fact that two thirds of women experience ‘brain fog’, during perimenopause, the years leading up to menopause. And it’s natural to wonder, is this the start of a slippery slope to dementia? GP Dr Ginni Mansberg, author of Save Your Brain, discusses what causes women to start to feel fuzzy-brained during perimenopause, and if there's a link to dementia. She also reveals the important lifestyle changes in your 40s and 50s that can have a huge impact on your risk of developing dementia later on. Because studies now show that up to a third of dementia cases can be prevented entirely, and in the rest can be delayed by as much as five years by doing things now to protect your brain.
