The Menopausal Brain with Kyler Hijmans
These insights are based on Kyler Hijmans, DNP, FNP-BC’s presentation at the June 23 Women’s Wellness Event: Menopause Reimagined. During the session, Kyler explored the menopausal transition through a neurological and systems-based lens, highlighting how declining estradiol and related hormonal shifts influence brain structure, metabolism, and function. The discussion focused on how menopause is not only a reproductive transition, but also a brain transition that can affect cognition, mood, sleep, and stress resilience.
Menopause is often discussed in terms of hormonal shifts, but its impact extends far beyond reproductive biology. One of the most important, and often least understood, areas of change occurs in the brain.Declining estradiol plays a central role in brain changes during menopause. These hormonal shifts trigger structural, metabolic, functional, and molecular changes throughout the brain that can influence cognition, mood, sleep, and overall resilience. Research shows that brain-related symptoms affect up to 80 percent of women during the menopausal transition.
If you have ever felt like you “do not feel like yourself anymore,” you are not alone. These experiences are common, biologically driven, and often temporary with the right support.
The Three Major Brain Symptom Clusters in Menopause
Cognitive Changes, Often Described as Brain Fog
Many women report changes in cognition during menopause, including forgetfulness, difficulty concentrating, word-finding challenges, and mental sluggishness. These symptoms are often described as “brain fog” and are closely linked to hormonal changes that affect brain metabolism and neural signaling.
Mood Changes and Emotional Shifts
Depression and anxiety affect approximately 30 to 40 percent of women during the menopausal transition. Research shows that depression rates during this stage are two to three times higher than in premenopausal women.
These changes are influenced by multiple biological mechanisms, including altered serotonin and norepinephrine signaling, Hypothalamic-Pituitary-Adrenal (HPA) Axis dysregulation, and increased neuroinflammation. Together, these shifts can impact emotional regulation, stress tolerance, and overall mental well-being.
Sleep Disruption and Its Ripple Effects
Sleep disruption affects an estimated 40 to 69 percent of women during menopause. While vasomotor symptoms such as night sweats can play a role, sleep changes also occur independently of hot flashes due to hormonal fluctuations that influence the brain’s sleep-wake regulation systems.
Sleep disruption has a cascading effect on cognition, mood, resilience, and long-term brain health, making it one of the most important factors to address during this transition.
Protecting Brain Health During Menopause
Hormone Therapy as Part of a Broader Strategy
Hormone therapy may help support brain health during menopause when used appropriately and under clinical guidance. It can work synergistically with nutrition, exercise, and lifestyle interventions to support overall cognitive and emotional resilience. Patients are encouraged to discuss individualized options with their provider as part of a comprehensive care plan.
Cardiovascular Health Is Brain Health
Menopause is both a cardiometabolic and neurobiological transition. The same systems that support cardiovascular health also play a critical role in protecting the brain.Annual screening of key markers such as blood pressure, lipid levels, blood sugar, metabolic health, and overall cardiovascular risk can help identify early opportunities for intervention.
A core principle in brain health is simple but powerful: protecting the brain begins with protecting the blood vessels.
Exercise: The Most Powerful Non-Hormonal Brain Intervention
Exercise is one of the most well-supported non-hormonal interventions for brain health during menopause. It has been shown to increase gray matter volume, improve cerebral blood flow, enhance production of brain-derived neurotrophic factor, support IGF-1 signaling, and improve executive function and memory.
Effective approaches include aerobic exercise, resistance training, balance training, and multicomponent movement programs. Movement is medicine for the menopausal brain.
Nutrition and Lifestyle Foundations
Nutrition plays a critical role in supporting brain health during midlife. Key focus areas include omega-3 fatty acids, blood sugar regulation, anti-inflammatory eating patterns, and adequate protein and nutrient intake. These inputs support both brain metabolism and systemic resilience.
Psychosocial and Cognitive Support
Psychological and social interventions are also important components of brain health. Cognitive behavioral therapy, mood support strategies, cognitive symptom management tools, and strong social connection can all help support emotional regulation and cognitive clarity during menopause.
The Nervous System in Menopause
Hormonal shifts also influence how the nervous system responds to stress. Many women experience increased sensitivity to chronic stress, sleep disruption, and emotional overload during this time. Changes in the HPA axis can lead to heightened cortisol reactivity and a reduced ability to recover from stress. As a result, experiences that once felt manageable may begin to feel more taxing.
The Hidden Challenge of Overfunctioning Culture
For many women, midlife symptoms are compounded by lifestyle and cultural pressures. Years of caregiving responsibilities, productivity demands, perfectionism, emotional labor, and chronic self-sacrifice often leave little room for recovery.
Many women reach this stage having spent years taking care of everyone except themselves.
Recovery Becomes a Core Health Strategy
During menopause, recovery is no longer optional. It becomes a foundational health strategy that supports both brain and body resilience. Key recovery domains include sleep, stress reduction, movement, nutrition, connection, purpose, and lifelong learning or novelty. The brain thrives in environments characterized by safety, connection, movement, adequate sleep, challenge, and meaning. It does not thrive in chronic overwhelm.
Key Takeaways
Brain fog, mood changes, and sleep disruption are common and biologically driven during menopause. Menopause is not only a reproductive transition, but also a brain transition shaped by hormonal, metabolic, and neurological changes. The same behaviors that support longevity also support brain health, and recovery, resilience, and nervous system regulation become increasingly important during midlife.
There is a great deal that can be done to support cognitive function, emotional well-being, and overall quality of life during this transition.
