Confusion, forgetfulness, and difficulty concentrating are all telltale signs of brain fog. For many women going through perimenopause, brain fog is a big concern. As many as two-thirds of women going through menopause report experiencing symptoms of brain fog.

“I am just not the same. Hot flashes constantly consume my days, my mood fluctuates without warning, and I feel foggy,” a woman surveyed by ThisIsMenopause reported.

Another woman said, “It has messed up my ability to sleep well, which leads to more brain fogginess and irritability.”

This article will explain the link between perimenopause — the time leading up to menopause when a woman’s periods permanently end — and brain fog. Understanding these connections can help you take steps to relieve this aggravating symptom.

What Exactly Is Brain Fog?

Brain fog occurs when the mind feels cloudy and cognitive function is affected temporarily.

Most people occasionally experience some degree of temporary brain fog due to common circumstances, such as poor sleep, depression, or stress. It can also be linked to a medication side effect or to a health condition, such as an autoimmune disorder, diabetes, migraine, or menopause.

Perimenopause and Brain Fog

In perimenopause, levels of the hormone estrogen begin to drop. Medical researchers don’t fully understand how decreasing estrogen levels may affect the brain. But they do know that estrogen receptors can be found throughout the body, including the brain, and that the body is very sensitive to hormonal changes.

Research has also shown that the brain goes through structural changes during perimenopause and menopause. There’s evidence that gray matter may decrease in regions of the brain that are associated with cognitive function, including thinking, decision-making (executive function), and memory.

Verbal memory and visuospatial memory (related to visual perception, depth, and distance) are areas of cognitive performance that are especially affected by the loss of gray matter. Fortunately, some research has indicated that some of the brain’s gray matter that’s lost during perimenopause may be restored postmenopause.

It’s important to note that perimenopause and menopause are part of a natural aging process. Aging in general is linked to occasional brain fog.

Perimenopause Symptoms, Poor Sleep, and Brain Fog

Some related conditions and symptoms of perimenopause may be an underlying cause of brain fog as well. For instance, many menopausal women experience insomnia (difficulty sleeping), which can lead to daytime sleepiness, fatigue, and brain fog. Poor sleep can be linked to common symptoms of perimenopause, such as night sweats, hot flashes, depression, and anxiety, all of which can interfere with sleep.

What Women Are Saying About Brain Fog

“It has messed up my ability to sleep well, which leads to more brain fogginess and irritability.”

“I have many symptoms that have caused me to feel stressed and overwhelmed. I have brain fog, hot flashes, mood swings, and frozen shoulder. It’s been extremely emotional, exhausting, and painful.”

“The brain fog is due to lack of sleep. I’m tired all the time because of the night sweats, ” a woman told ThisIsMenopause.

Another woman wrote, “I have many symptoms that have caused me to feel stressed and overwhelmed. I have brain fog, hot flashes, mood swings, and frozen shoulder. It’s been extremely emotional, exhausting, and painful.”

Sleep may also be affected by other health conditions that can occur in perimenopause. Perimenopausal women have an increased risk of developing sleep apnea, a breathing disorder that disturbs sleep.

Hormone fluctuations also raise the risk of developing restless legs syndrome (RLS), which women are prone to developing. RLS causes discomfort in the legs and creates a sensation of needing to move your legs, particularly while resting. RLS is known to cause sleep problems.

Habits and Lifestyle Changes That Can Help Relieve Brain Fog

If brain fog is interfering with your quality of life, you can make lifestyle changes that may help ease your brain fog and support your overall brain health. These include:

• Getting regular exercise to help boost your energy and improve your physical and mental well-being
• Avoiding excessive alcohol, intoxicating substances such as marijuana, and smoking cigarettes
• Managing stress through meditation, mindfulness training, and relaxation exercises
• Eating a nutritious diet with plenty of vegetables and fruits rich in antioxidants
• Getting enough sleep by following healthy sleep practices, such as having a sleeping schedule, avoiding electronic screens and television before bedtime, and keeping your bedroom quiet and comfortable

You can also take steps to aid your memory and brain function, including:

• Keeping notes or using a diary to organize your day
• Engaging in activities that stimulate your brain, such as learning a language, playing word games, reading, and learning how to paint or play a musical instrument
• Challenging yourself by changing your routines, such as taking a new route to a familiar destination
• Taking regular breaks to help prevent mental exhaustion

• Undergoing psychotherapy or mental health counseling, such as cognitive behavioral therapy, which can help control negative thinking and support healthy habits

Menopause Treatment and Brain Fog

If brain fog is negatively affecting your daily life, be sure to talk to a healthcare professional with expertise in women’s health and menopause. They can talk with you about treatment options for symptoms of menopause.

Menopause hormone therapy (also called hormone replacement therapy or HRT) is one treatment option that may relieve some menopausal symptoms, and some evidence suggests it may improve cognitive symptoms like brain fog. HRT works by replacing estrogen and progesterone, sex hormones that decrease during perimenopause.

Studies have shown that hormone therapy can be effective in treating brain fog in women in perimenopause and those who are early postmenopausal. However, there’s evidence that hormone therapy may worsen cognitive symptoms in postmenopausal women who are older. It’s essential to talk to your doctor about your individual risks before starting hormone therapy or another treatment for menopausal symptoms.

Brain Fog May Be a Sign of Another Health Condition

In some cases, brain fog may indicate another health condition that could need medical attention. If you’re in perimenopause and have brain fog, it’s important to seek medical advice to determine if your brain fog is related to hormonal shifts or another underlying health problem.
