Menopause Brain Fog: Why it Happens During Midlife

Do you ever walk into a room and forget why you entered? Do you ever forget a familiar word mid-sentence? Do you ever feel like no matter how hard you try to concentrate, you just can’t seem to focus? If you are a female in your 40s or 50s, you are not alone. This concept, called menopause brain fog, is a common symptom of this crucial hormonal time period. Turns out, the hormonal shifts that occur during this phase, not only affect your menstrual cycles, but can have additional effects on your cognitive functionality. But don’t worry, there are a few things you can do that may help to alleviate this symptom.

The female hormones involved with reproduction, estrogen and progesterone, do far more than simply regulate the menstrual cycle. These hormones are actively involved in the brain, due to their role in vascular health. Both estrogen and progesterone act as vasodilators, meaning that they relax vascular cells, widening blood vessels, which increases blood flow4. For veins in the brain, this is a critical way to increase blood flow to brain tissue, subsequently increasing cognitive performance.

During perimenopause, your body is experiencing rising and falling levels of both estrogen and progesterone. These swings in hormone levels produce all of the symptoms most commonly associated with menopause including hot flashes, sleep disturbances, dry skin, thinning hair, and, you guessed it, brain fog5.

Stress and emotional well-being can also play a role. When you are under a considerable amount of stress, your working memory and attention are strained. The stage of midlife often results in a high level of stress as many individuals are still caring for their own children, but now are also caring for their aging parents. In addition to this, one might experience career pressure as well as typical daily stressors.

Taken together, these symptoms often compound on each other, overlapping and reinforcing each other, making brain fog feel even more pronounced.

It’s important to ensure the symptoms of brain fog are not resulting from nutrient deficiencies. Some nutrients like vitamin B12, vitamin D, and omega-3 fatty acids have a big role in concentration. Your doctor will be able to run a simple test to determine if you are deficient in any of these nutrients. If so, you’d likely be able to correct this through diet and supplementation.

Lastly, it’s possible that the fogginess you are experiencing is a result of blood sugar spikes and dips. When we eat, our blood sugar naturally rises. Our body works to move that sugar into our cells to power them. However, if we eat meals with too much sugar and not enough protein and fiber, we may experience a rapid rise in blood sugar and subsequent crash. These blood sugar swings could be the source of your brain fog.

In addition to nutrition, physical activity also plays a role in cognitive health. This is because of its ability to increase blood flow, around the body, but especially in the brain. Research shows that exercise is associated with reduction in cognitive decline as well as other brain health benefits including increased sleep and improved mood11.

Lastly, as we age, research shows that mental stimulation and “brain exercise” is important to reduce cognitive decline. It’s recommended to regularly partake in simple brain-boosting activities like puzzles, crosswords, Sudoku, etc. By challenging the brain, you can help to keep your mind sharp12.
