Many women experience changes during menopause that they hadn’t known before. One of the most common, yet lesser-known symptoms is "brain fog," which affects about 60% of women in this phase of life. But what exactly is behind it, and what can you do about it?
What is brain fog?
Brain fog describes a range of cognitive (related to thinking and memory) symptoms that often appear gradually. These include concentration difficulties, forgetfulness, and a general mental fatigue. It feels like a "fog" has descended on your mind, making even simple tasks require more energy. This typically occurs in late perimenopause and early postmenopause, and the intensity can vary from one woman to another.
Common signs of brain fog include:
Short-term memory issues: Names, appointments, and tasks are forgotten more easily, creating challenges in both daily life and work.
Concentration difficulties: Tasks that were once easy may now require more time and focus.
Word-finding problems: Finding the right words can be tough, especially in group discussions or presentations.
Reduced multitasking ability: Doing several things at once becomes harder or even impossible.
Confusion or disorientation: Familiar situations may suddenly feel strange.
Why does brain fog happen?
The primary cause of brain fog is the decrease in estradiol during menopause. Estradiol is essential for brain cell health and supports cognitive processes like memory and concentration. When levels drop, mental performance can suffer. Additionally, sleep deprivation and stress, also common during menopause due to hormonal shifts, can worsen symptoms. Chronic stress may elevate cortisol levels, which further impacts brain function.
How is brain fog diagnosed?
Unfortunately, there is no clear diagnostic test for brain fog, as it involves a collection of subjective symptoms that are often hard to measure. The first step is a thorough conversation with a medical expert. During this discussion, your experiences and symptoms will be reviewed to rule out other potential causes, such as thyroid disorders, vitamin deficiencies, or sleep disturbances. In some cases, cognitive tests, such as the Mini-Mental State Examination (MMSE), may be helpful to assess concentration and memory and to determine if there are actual impairments. It’s important not to dismiss brain fog as a “normal” part of aging – the better you can describe your symptoms, the more effectively your doctor can find suitable treatment options.

What can you do about brain fog?
There are several approaches that may help alleviate symptoms:
Regular exercise: Physical activity has positive effects on the brain. Just 150 minutes of moderate exercise a week, like walking or swimming, can improve mental performance.
Healthy diet: A balanced diet rich in fruits, vegetables, omega-3 fatty acids, and whole grains supports brain health. A Mediterranean-style diet is particularly beneficial for cognitive health.
Stress reduction: Techniques like meditation, yoga, or breathing exercises can help reduce stress, which can worsen brain fog.
Good sleep: Lack of sleep intensifies brain fog. Stick to regular sleep hours and create a cool, dark sleeping environment to improve sleep quality.
When brain fog strikes, even routine tasks at work can feel overwhelming. Delivering presentations, managing complex data, or operating machinery can become challenging and error-prone. Targeted menopause support measures, such as providing access to menopause-specific treatments or awareness programs enhance well-being and contribute to increased safety and overall productivity in the workplace.
What else can help?
If you have chronic conditions such as high blood pressure (hypertension) or diabetes, it’s especially important to manage them well, as these can also impact your brain and worsen symptoms like brain fog.
High blood pressure (hypertension): Persistent high blood pressure can strain brain blood vessels and reduce circulation, making concentration and memory more difficult. Proper blood pressure control – through medication, reducing salt, and regular exercise – can help protect mental clarity. Talk to your doctor about the best steps.
Diabetes: Poorly controlled blood sugar can affect the brain, as high levels can damage nerves and blood vessels, impacting memory and focus. Managing blood sugar through diet, exercise, or medication can make a big difference. You don’t have to do it alone – get the support you need.
Smoking and alcohol: Smoking constricts blood vessels, reducing oxygen supply to the brain. Excessive alcohol can impair brain function and worsen brain fog. Reducing or quitting smoking and cutting back on alcohol can benefit both your brain and overall health.
