Do you ever find yourself struggling to find the right words? Wondering why you walked into a room? Or forgetting plans you’ve made? While brain fog may be more common with age, that’s not the whole story.
Many women report experiencing brain fog during menopause. However, without understanding this connection, it’s easy to feel alone or worry that it’s all in your head. Some women have also reported feeling scared that they may have dementia.
But research shows that brain fog is a very real symptom of menopause, with around 44% to 62% of women noticing some form of cognitive decline. While brain fog can be frustrating and upsetting to live with, the good news is that changes appear to be temporary.
With that said, we’ll take a closer look at what the research says about the link between menopause and brain fog.
What is brain fog?
Brain fog is a common, and often debilitating, menopause symptom that affects your memory, focus, and other cognitive abilities.
For example, you may struggle to find a simple word, misplace things, lose your train of thought, or find yourself re-reading the same information over and over because you can’t seem to take it in. In this study, around 72% of menopausal women reported problems remembering names at least some of the time, and 50% said they had trouble remembering where they put things and what they were doing. Many women say that brain fog makes their brains feel like ‘cotton wool’.
According to experts at Menopause Care, brain fog can occur at any stage of perimenopause or menopause, and there isn’t a specific timeframe for how long you may experience it.
While brain fog isn’t exclusive to menopause – for example, your brain may feel sluggish when you’re unwell or jetlagged – research shows that the two are linked. We’ll explore this below.
What’s the link between menopause and brain fog?
Research suggests that the hormonal changes which occur during menopause, particularly the decline in oestrogen, can contribute to brain fog.
Oestrogen is an essential hormone that supports brain health. According to experts, among other things, oestrogen affects…
- Neurotransmitter activity – oestrogen improves the function of neurotransmitters, like dopamine and serotonin, which are key for mood regulation, focus, and memory.
- Blood flow to the brain – oestrogen plays a role in vascular health, helping to ensure enough oxygen and nutrients reach the brain.
- Neuroprotection – oestrogen protects neurons (cells that send and receive messages from the brain back to the body) and encourages their growth and function.
When oestrogen levels decline, these processes are interrupted, which can affect brain function and cause symptoms of brain fog. For example, studies show an overall reduction in brain energy levels just before and during menopause.
It’s also worth noting that other menopausal symptoms, such as hot flushes and night sweats, can often interfere with sleep quality – making it even more difficult to focus, process information, and remember things.
Plus, alongside oestrogen, lower testosterone levels may contribute to brain fog. While most people associate testosterone with men, women produce it in smaller amounts, too, with levels declining as you enter your 30s and dropping around the time of perimenopause and menopause. Testosterone helps strengthen nerves in the brain, support overall energy, and strengthen arteries that supply blood to the brain, all of which are crucial to protect against memory loss.
What impact can brain fog have on women?
While not every woman going through menopause will experience brain fog, research suggests that it’s a fairly common symptom. For example, in this study, which followed a group of women through menopause, around two-thirds reported having memory issues.
Brain fog can be frustrating, upsetting, and worrying to deal with, and can impact daily life. For example, you might struggle to function at work, socialise, or carry out simple tasks like reading or even stringing a sentence together. Many women also begin to doubt themselves during this time, and research has linked brain fog with an increased risk of anxiety and low self-esteem.
Some women may even start to worry whether they have dementia, which can be particularly scary if you have a family history of the condition.
Is brain fog during menopause temporary?
Although menopausal brain fog can be difficult to deal with, the research is reassuring. Many studies suggest that it’s usually only temporary and not an indication of permanent cognitive decline. For example, experts at Menopause Care say brain fog tends to be most prominent during perimenopause but often resolves after menopause.
Similarly, neuroscientist Doctor Lisa Mosconi, who’s carried out the largest study of the brain during menopause to date, explains that, during menopause, the brain goes through a period of transition and needs time to adjust. Because of this, it compensates by increasing blood flow and energy production, and eventually rebounds.
Take the results of this study, which measured women’s cognitive performance. It found that before menopause, women could improve their verbal memory and processing speed with practise; but during menopause, their performance didn’t improve with practice. However, after menopause, women were once again able to improve their performance with practise.
Are some women more likely to experience brain fog during menopause than others?
Every woman’s experience of menopause is different, which means symptoms can vary significantly. Some women may be more likely to experience brain fog than others, and research points us to a couple of potential risk factors.
This study found that perimenopausal women who experienced depression, sleep issues, and vasomotor symptoms (such as hot flushes and night sweats) were more likely to have cognitive difficulties.
Ethnicity may also play a role, as, according to this study, Black or Hispanic people may be at greater risk of brain fog than South Asian people.
However, further research is needed to confirm these findings.
Can hormone replacement therapy help with brain fog?
While it can be reassuring to know that menopausal brain fog doesn’t usually last, it can still be upsetting and frustrating to deal with. For some women, it can have a significant impact on daily life, particularly if it leads to issues like social anxiety. So, you might be wondering what treatment is available.
Hormone replacement therapy (HRT) is a treatment used to help women manage symptoms of menopause. It works by replacing the hormones in your body that decline during menopause, including oestrogen. Many women find HRT useful for managing symptoms like hot flushes, mood swings, and vaginal changes – and there’s some evidence to suggest that it can be useful for brain fog, too. However, the research is still uncertain.
Some studies suggest that the effectiveness of HRT for brain fog depends on factors like timing, dosage, and medical history. For example, there’s evidence that starting HRT early in menopause (within the first 10 years of onset) may reduce the risk of Alzheimer’s disease. However, further research is needed.

4 tips for managing brain fog
While it’s not always possible to entirely prevent brain fog during menopause, research suggests that certain lifestyle changes can help to ease symptoms and improve memory overall.
We’ll cover some of these ideas below. For further reading, you might also like to read our article: 10 ways to beat brain fog.
Note: It’s important to remember that everyone is different and, as a result, there’s no one-size-fits-all formula. When navigating menopause, the most important thing is to treat yourself with kindness and compassion, and remember you can only do your best.
1. Eat plenty of antioxidants
Experts have identified a clear link between what we eat and our bodies’ hormone balance.
Beyond eating a healthy, balanced diet centred on whole foods, several nutrients may be particularly beneficial for boosting brain health. This includes antioxidant-rich foods.
For example, diets rich in vitamins A, C, E, and polyunsaturated fatty acids, like omega-3s, have been linked with slower cognitive decline.
This is because, when the body burns glucose for energy, free radicals (unstable molecules) are produced. If left unchecked, these harmful molecules can negatively affect the body by making cells age faster and work less efficiently.
Since the brain uses more energy than any other part of the body, it’s more vulnerable to harm from free radicals. But, according to The Menopause Charity, antioxidant-rich diets can help balance them and minimise their effect on cells.
2. Harness the power of exercise for brain health
Exercise is important for brain health for various reasons and has been linked with better memory, improved focus, and slower cognitive decline.
Among other things, exercise helps increase blood flow and oxygen delivery to the brain, reduces insulin resistance and inflammation, and releases hormones that support brain health.
And the good news is that it doesn’t have to be anything drastic: just two weekly sessions of strength training have been found to have clear benefits for the brain, and simple coordination exercises, such as bouncing a ball, may help to boost concentration.

3. Plan ahead
Planning ahead can help if you struggle with anxiety caused by brain fog. For example, you might find it useful to keep a diary and schedule in preparation time for tasks to allow yourself a chance to refocus and prepare.
Some women also report using alarms, reminders, and note-taking tools, such as Post-it notes, to help them stay organised.
4. Try not to isolate yourself
It can be tempting to isolate yourself when you have brain fog, particularly if your memory is impacted. However, it’s important to have people around you that you can rely on for support.
Plus, socialising can actually help to stimulate your memory. According to experts, spending time with loved ones over stimulating activities like board games, reading, and crafts can be particularly beneficial. It can help to take your focus off brain fog, too.
Examples of support networks include family, friends, and peer support groups. Many people find it particularly valuable to connect with others who have shared experiences.

Final thoughts…
Because it’s not always easy to spot and isn’t widely spoken about, experiencing brain fog during menopause can sometimes feel like a taboo topic. However, research shows that brain fog is a very real – and common – symptom of menopause. So, it’s important to remember that you’re not alone.
While brain fog can’t always be prevented, research suggests its effects are only temporary. And lifestyle changes can often help manage its impact.
