“Why can’t I think straight anymore?”
If you’ve ever walked into a room and forgotten why, struggled to find a word mid-sentence, or felt like your brain has turned to cotton wool, you’re not alone. Many women in their late 30s and 40s, often juggling careers, family, and a never-ending to-do list, find themselves suddenly battling brain fog as they move through perimenopause.
We want you to know that you’re not going mad, and you don’t just have to “put up with it.” Brain fog is one of the most common and frustrating symptoms of perimenopause, but with the right support, you can regain the confidence, and focus you need.
What exactly is brain fog?
The British Menopause Society and NICE guidelines recognise brain fog as a key symptom of perimenopause and menopause. It’s not a medical diagnosis, but rather a cluster of symptoms that can include:
- Forgetfulness
- Struggling to concentrate
- Losing your train of thought mid-conversation
- Difficulty processing information
- Feeling mentally slower than usual
For many women, this isn’t just inconvenient, it’s deeply unsettling. You may feel less capable at work, disconnected at home, or like you’ve lost a part of yourself. That can chip away at your confidence, leaving you worried about your future.
Why does brain fog happen in perimenopause?
Hormones play a huge role in how your brain functions. During perimenopause, levels of oestrogen and progesterone fluctuate and eventually decline. Oestrogen in particular supports the brain chemicals that affect memory, focus, and mood. When levels drop, it can disrupt how your brain processes and retrieves information.
But hormones aren’t the only piece of the puzzle. Brain fog can also be linked to:
- Sleep problems – Night sweats, insomnia, and restless sleep reduce your brain’s ability to reset.
- Stress and cortisol – Chronic stress puts your brain into survival mode, making focus harder.
- ADHD or neurodiversity – Symptoms of attention difficulties can feel worse in perimenopause.
- Lifestyle factors – Nutrition, alcohol, exercise, and screen time all play a role in how your brain functions.
When you add in the relentless demands of modern life – emails, deadlines, family needs, it’s no wonder your brain feels overloaded.
The good news: brain fog is not permanent
This is important to hear: brain fog doesn’t mean you’re losing your memory for good. It doesn’t mean dementia is around the corner and it doesn’t mean you’re incapable.
What it does mean is that your brain and body are asking for support. When we address the underlying causes, whether that’s hormones, sleep, stress, or lifestyle, most women see real improvements.
What you can do about brain fog
At The Dr Jenni Clinic, we help women just like you cut through the confusion and find real solutions. Here are some of the most effective ways we support our patients:
For many women, carefully tailored hormone replacement therapy (HRT) can make a significant difference. NICE guidelines support HRT as a safe and effective option for managing perimenopause symptoms, including brain fog. By restoring hormonal balance, you give your brain the environment it needs to function at its best.
- Sleep reset
You can’t think clearly when you’re not sleeping well. We look at why you may be struggling, whether that’s hot flushes, anxiety, or restless nights and build a plan to help you get restorative sleep.
- Stress and lifestyle support
Managing stress isn’t about adding another job to your list. It’s about practical, achievable changes that reduce cortisol levels and give your brain space to recharge. This might include nutrition support, movement, or small daily habits that make a big difference.
- Looking at the bigger picture
Sometimes, brain fog overlaps with other conditions, such as ADHD or thyroid issues. We take the time to explore all possibilities, so nothing is missed.
Imagine this…
Instead of losing your train of thought in meetings, you’re back to contributing with clarity and confidence. Instead of feeling guilty for snapping at your family, you’re more present and connected. Instead of worrying that you’ve lost yourself, you know exactly what’s happening in your body and how to take charge of it.
That’s the transformation we see every day. With the right support, you can move from foggy and frustrated to focused and in control.
