If you're experiencing brain fog, difficulty focusing, forgetfulness, or memory lapses, know that you're not alone. 62% of women in midlife have memory problems during perimenopause and menopause, including difficulty concentrating, recalling or remembering words and names, retaining new information and take more time to process new information.
You may find yourself losing things, struggling to switch tasks, having difficulty making decisions, or having trouble sticking with a book or a television show. For those experiencing it can be concerning. But it's important to understand it's a normal part of a woman's midlife transition.
During this time, parts of your brain that help with memory are changing, so what you're experiencing is real, not just in your head. The way your brain cells talk to each other and use energy is changing too. You might only have mental fog and trouble focusing, or you might have these along with other menopause symptoms.
The changes in how your brain cells are structured, communicate, and utilize energy during this period confirm that your experiences of mental fog are indeed real.
At the same time it's reassuring to know that the brain adapts to these changes occurring during the midlife transition and most of these symptoms improve after menopause.
Women's Brains Age Differently Than Men’s
When women go through the menopause transition, their brains change in ways that are different from men of the same age.
Men have testosterone, which serves as a protector for their brains. Estrogen is women’s brain protector, helping brain cells use energy and stay healthy. Unlike women, men don't experience a rapid loss of their main sex hormone. Instead, testosterone decreases gradually, leading to a more gradual change in their brains.
However, for women estrogen fluctuates throughout her life starting with puberty, menstruation, pregnancy, perimenopause and the dramatic reduction with menopause.
The rise in estradiol (a form of estrogen) leads to the growth of neurons and an increase in verbal memory. When estrogen decreases and progesterone increases, the neurons can shrink. This could explain why women feel tired at certain times in their menstrual cycle or have trouble focusing during perimenopause.
This understanding is important because it helps us appreciate the unique challenges women face during these transitions. Knowing your brain and body are changing can help you be kinder to yourself during these times.
The good news is that the brain typically adjusts to these changes over time.
The Menopause Brain: A Time of Reorganization
Researchers have found that during perimenopause, women experience a temporary decline in learning abilities compared to their premenopausal levels. However, cognitive performance improves back to premenopausal levels after menopause, suggesting that these challenges are short-lived.
For any middle-aged women questioning their cognitive abilities, a Harvard study offers reassurance. It found that middle-aged women outperform men in memory tasks, regardless of menopause. These women maintained impressive overall performance, despite a slight dip in memory skills noted during menopause.
Another study reporting on brain scans of women who have gone through menopause show some interesting things. The amount of gray matter, which is important for memory and thinking, goes back to normal after menopause.
During menopause, the brain's white matter decreases, but the connections and communication between brain cells get better. This might mean that women’s brain networks work more efficiently once menopause starts.
If you're concerned about brain fog and other symptoms during menopause, know that they are normal and natural. As women age, their brain adjusts and memory and thinking abilities often stay strong or get better after menopause.
Is Your Brain Fog a Sign of Something More? Understanding Alzheimer's Risk for Women
One can confuse menopause brain fog and early dementia with each other. Both can have memory loss, difficulty recalling recent events, and losing items like keys and glasses.
During menopause, you might forget to add sugar to your coffee, akin to overlooking an ingredient while cooking. With dementia, it's more like forgetting how to make the coffee altogether, similar to losing the recipe for a dish you've made for years.
This distinction becomes particularly relevant when considering the impact of Alzheimer's on women. Alzheimer's disease, the most common cause of dementia, affects more women than men. In fact, for every man dealing with Alzheimer's, there are two women facing the same challenge.
In fact, women in their 60s have a higher likelihood of developing Alzheimer's compared to breast cancer.
New studies are investigating the link between menopause and Alzheimer's, particularly the link to decreased estrogen levels.
We usually think of menopause as a middle-aged phase and Alzheimer's as something that happens in older age.
But studies show that the groundwork for Alzheimer's could start much earlier than when we see the symptoms.
They have found an increase in the formation of amyloid plaques in the brain, which are linked to Alzheimer's in women during menopause, unlike in middle-aged men.
But here's something important to remember, not every woman who develops these plaques will end up with dementia. They're a risk factor, sure, but they don't spell out a definite future with Alzheimer's.
This information is important because it tells us when we might start looking out for these changes.
Menopause typically begins in women's early 50s, but it can also start earlier. Some women experience premature menopause naturally, while others may go through it earlier due to medical procedures like a hysterectomy or oophorectomy, which involves the removal of the ovaries.
Regardless, premature menopause comes with an increased risk of dementia. This is not to suggest you should avoid these procedures if you need them. However, it's important to understand their overall impact on your brain health.
How to Reduce Brain Fog and Risk of Dementia
Good news! Research shows we can reduce dementia risk and improve brain health by what we do. Simple adjustments to our everyday routines can lead to significant improvements in our cognitive well-being.
Eating for a Healthy Brain
The Mediterranean diet is a great way to take care of your health, especially for women. It cuts breast cancer risk by half and reduces the chances of heart problems and depression.
This diet is not just nutritious; it's rich in phytoestrogens. These natural compounds found in plants that act like mild estrogens in our bodies. Adding flax seeds, sesame seeds, dried apricots, legumes, and crunchy fruits, along with dark chocolate, essential for cognitive health.
The Power of Exercise
The most consistent thing that improves brain health for women in midlife is exercise. Studies show women who engage in regular exercise have a up to a 30% reduced risk of developing dementia, than women who do not exercise. This reduced risk is as high as 90% in women with high physical fitness in their middle years.
Managing Stress for Brain Health
Small amounts of stress are good for us, but prolonged stress can degrade brain performance, magnifying brain fog symptoms. Managing stress is therefore vital. Simple activities such as walking, yoga, meditation, or any relaxing hobby can help lower stress levels.
Getting Good Sleep
Sleep problems are another issue to address. Adequate sleep is essential for brain health. It allows our brain to rest and recover, playing a significant role in working memory and cognitive function. Having a regular sleep schedule with meditation, no screens before bed, and a comfortable sleep environment can improve sleep quality.
Staying Socially and Mentally Active
Maintaining social connections and engaging in mentally stimulating activities are key to keeping our brains active. Doing puzzles, trying new hobbies, and spending time with loved ones keeps our minds active and sharp.
Staying Hydrated
As we grow older, our brains become more sensitive to dehydration, which can lead to increased brain fog and trouble concentrating. This is especially important to consider when consuming alcohol, as it can contribute significantly to dehydration.
Given this, staying hydrated is crucial, particularly when drinking alcohol or caffeine. Maintaining good hydration helps counteract the dehydrating effects of these substances and is vital for preserving brain health.
Drinking plenty of water and hydrating fluids can help your brain deal with aging challenges, like worsening brain fog.
Modifiable Risk Factors
The more risks you have, the greater chance of negative health outcomes. Modifiable risk factors are things we can do, change or control. Other ways to protect your brain are to not smoke and limit alcohol. Controlling diabetes and your blood pressure help lessen your risk for cognitive decline.
Does Hormone Replacement Therapy Reduce Brain Fog and Dementia?
The research on Hormone Replacement Therapy (HRT) for brain fog and cognitive health is not clear yet.
HRT is the best treatment for hot flashes, night sweats, and preventing osteoporosis. However, there is no evidence that HRT directly improves cognitive abilities when started in post-menopause. If you take HRT for your disruptive hot flashes and night sweats, HRT may improve sleep and fatigue, mood, your ability to concentrate, and overall quality of life. This is because brain fog in midlife is not exclusively caused by your low estrogen, but also comes from other side effects seen in perimenopause and post-menopause like poor sleep, mood changes and hot flashes.
Women who take HRT over the age of 65 increase their risk for dementia and cognitive impairment.
Women in premature menopause (under 40) or immediately after full hysterectomy may see cognitive improvement from taking HRT.
Embracing Menopause as a Transition
It's important to recognize that menopause is a transition, not a decline. While it brings changes, it doesn't mean our brains are deteriorating. Most women find that post-menopause, their brain fog clears, and they feel better overall.
A brain-healthy diet, regular exercise, stress management, good sleep, social and mental engagement, can all contribute to reducing the risk of dementia and ensuring our brains remain healthy and vibrant as we age.
