"Hormones and Memory: Protecting Cognitive Health as You Age.”

Our memories are the building blocks of our lives—moments of joy with our kids, lessons learned (even those we’d prefer to forget), and all the experiences in between that define us. This is exactly why preserving cognitive health and memory becomes increasingly important throughout life. 

As we age, it’s natural to experience some changes in cognitive function, like occasional forgetfulness of the car keys or slower recall. However, there’s a more significant link between our hormones and brain health that goes beyond these usual shifts.

My aim with this blog post is to explore how these hormonal changes influence cognitive function and to offer practical insights for maintaining and improving brain health as you age. By understanding these connections, you can take proactive steps to support your cognitive well-being and enjoy a sharper, more vibrant mind throughout the years!

The Connection Between Hormones and Memory

When you think of hormones, what springs to mind? Probably all things PMS. However, hormones don’t only play a role in reproductive health–they also aid in maintaining cognitive function and memory, influencing how we think, remember, and process information. As we age, changes in key hormones can significantly impact our brain health.

Let’s take a look at three of our key hormones and how they can impact memory:

1. Estrogen: This hormone is vital for brain health, particularly in women. Estrogen supports various cognitive functions, including memory, learning, and emotional regulation. It enhances synaptic plasticity—the brain's ability to adapt and form new connections—which is crucial for memory formation and retention. As women enter menopause and estrogen levels decline, they may experience increased memory difficulties and cognitive decline. PMID: 35873026

2. Testosterone: Although often associated with male health, testosterone also affects cognitive function in both men and women. It plays a role in maintaining memory, attention, and spatial abilities. Low levels of testosterone, which can occur with age or other factors, have been linked to reduced cognitive performance and an increased risk of cognitive decline.

3. Cortisol: Known as the stress hormone, cortisol helps manage the body's response to stress. However, chronic high levels of cortisol, often due to prolonged stress, can negatively impact brain function. Elevated cortisol can impair memory formation, reduce cognitive flexibility, and increase the risk of neurodegenerative conditions.

Hormonal Changes with Aging

Unfortunately, getting older means that hormonal changes are inevitable. Understanding these changes helps us better manage and support our brain function throughout different life stages:

Estrogen

During the reproductive years, estrogen levels fluctuate naturally, but the most significant changes occur during menopause. As estrogen levels decline during menopause, many women experience cognitive changes, including memory lapses, slower recall, and difficulty concentrating. This decrease in estrogen can also lead to increased risk of cognitive decline and neurodegenerative diseases, such as Alzheimer's disease.

Testosterone

In men, testosterone levels naturally decline with age, which can affect various aspects of cognitive function, including memory, attention, and spatial abilities. Lower testosterone levels in both sexes are linked to reduced cognitive performance and an increased risk of developing age-related cognitive conditions. Maintaining balanced testosterone levels is therefore important for preserving cognitive function.

Cortisol

Elevated cortisol can lead to structural changes in the brain, particularly in the hippocampus, which is crucial for memory and learning. Effective stress management and maintaining balanced cortisol levels are vital for protecting cognitive function as we age. PMID: 30881301

Strategies for Supporting Hormonal Balance and Cognitive Health

Maintaining hormonal balance as we age doesn’t have to be a monumental task. In fact, I find that by focusing on a few key pillars, it’s more than reasonable to effectively support your hormone levels and cognitive health. Here are the five strategies I swear by: 

1. Nutrition: This should be your first port of call. A balanced diet plays a crucial role in supporting both hormonal balance and cognitive health. Key nutrients include:

• Omega-3 Fatty Acids: Found in fatty fish like salmon, flaxseeds, and walnuts, omega-3s are essential for brain health. They support cognitive function and help reduce inflammation, which can impact hormone levels and brain health.

• Antioxidants: Foods rich in antioxidants, such as berries, dark chocolate, and green tea, help protect the brain from oxidative stress and damage. Antioxidants also support hormonal balance by reducing inflammation.

• B Vitamins: B vitamins, including B6, B12, and folate, are important for brain function and the synthesis of neurotransmitters. They can be found in whole grains, lean meats, and leafy greens.

2. Exercise: Regular physical activity offers numerous benefits for hormonal balance and cognitive function. Try to make your exercise something you enjoy as you’re more likely to stick with it that way. Here are two key benefits: 

• Enhancing Hormone Levels: Exercise helps regulate hormones such as estrogen, testosterone, and cortisol, contributing to overall balance.

• Improving Cognitive Function: Physical activity boosts blood flow to the brain, promotes neurogenesis (the growth of new neurons), and enhances memory and cognitive performance. Activities like strength training and aerobic exercise are particularly beneficial.

3. Stress Management: Managing stress effectively can help lower cortisol levels and protect cognitive health. Try integrating these two practices into your everyday routine:

• Mindfulness: Practicing mindfulness techniques, such as meditation and deep breathing, can reduce stress and lower cortisol levels, improving cognitive function.

• Relaxation Exercises: Engaging in activities like yoga or progressive muscle relaxation can help manage stress and promote mental clarity.

4. Sleep: You should aim for 8-9 hours per night (I know it’s difficult for the moms out there, but try your best!) Quality sleep is vital for both hormonal balance and cognitive health:

• Regulating Hormones: Adequate sleep helps regulate hormones, including cortisol and estrogen, which are crucial for maintaining cognitive function.

• Supporting Cognitive Function: During sleep, the brain consolidates memories and clears out toxins. Aim for 7-9 hours of quality sleep each night to support overall brain health.

5. Hormone Testing: Regular hormone testing and consultations with healthcare providers are essential for personalized hormone management:

• Identifying Imbalances: Testing can help identify hormonal imbalances and guide targeted interventions to support cognitive health.

• Tailored Strategies: Working with a healthcare provider allows for the development of personalized strategies to address specific hormonal needs and enhance cognitive function.

Conclusion
Don’t underestimate the impact hormones have on influencing memory and cognitive function. As we age, hormonal changes, such as declines in estrogen, testosterone, and shifts in cortisol levels, can significantly impact our brain health. Recognizing this link underscores the importance of taking proactive measures to maintain cognitive vitality.
