If you’ve been forgetting things, struggling to concentrate, or feeling mentally fuzzy, it’s easy to blame stress, tiredness, or busy life.
In perimenopause, however, brain fog is often hormone-related.
Here’s why:
Oestrogen fluctuates, which affects neurotransmitters like serotonin, dopamine, and acetylcholine — all vital for memory, focus, and mental clarity.
Progesterone declines, which can impact sleep quality, and poor sleep directly affects cognitive function.
These hormonal changes can make it harder to concentrate, recall information, or stay organised — even if you’ve never had issues before.
💡 The key point: Feeling foggy or forgetful isn’t a weakness. It’s your body signalling that it’s navigating hormonal shifts.
Understanding this can help you approach symptoms with compassion — and take steps to support your brain and overall wellbeing.
