Menopause and the brain: beyond brain fog
Functional medicine practitioner Scotti McLaren explores how hormonal shifts can influence the way women think, feel, sleep, regulate and move through daily life - and why the brain deserves a wider role in the menopausal conversation.
Key takeaways:
Menopause affects the brain, not just the reproductive system.
Brain fog is only one part of the picture. Menopause can also affect the brain’s wider role in emotional regulation, stress resilience, sleep and the ability to cope with everyday demands.
These changes can feel harder to manage when the system is already depleted by chronic stress, poor sleep, burnout, sensory overload or years of masking.
For neurodivergent women, menopause can amplify traits or challenges they may have been managing for years, and the transition itself may feel more intense than it does for others.
Supporting the brain in menopause means moving beyond isolated symptoms and looking at the whole picture - hormones, sleep, blood sugar, nutrition, movement, stress load and recovery.
When people talk about menopause, the conversation often starts with hot flushes, night sweats and changes to periods.
But menopause goes beyond the reproductive transition. It is also a brain and nervous system transition.
Many women notice this before they have the language for it. The usual strategies for managing work, family, relationships and responsibilities may suddenly feel less reliable. It can feel as though the brain and nervous system are responding differently to everyday life.
For many women, the most unsettling part is not simply forgetting words or losing focus. It is feeling that their usual mental, emotional and physical reserves have changed. They suddenly don’t feel like themselves.
The term “brain fog” is too narrow to describe this. Menopause can affect the brain’s wider role - shaping how women think, feel, sleep, respond to stress and manage the energy demands of daily life.
At the end of this article, you’ll find details of Scotti’s free MenoMinds Academy workshop on menopause and neurodivergence: a story of amplification.
Guest article by Scotti McLaren, founder of Investigative Health
Scotti is a Geneva-based functional medicine practitioner specialising in women’s hormonal and brain health, with a particular focus on neurodivergent women’s physical, cognitive and emotional health.
Her academic background includes an MSc in Psychology and Neuroscience of Mental Health from King’s College London and a BSc in Nutritional Science from Middlesex University. Her clinical work explores how hormones, the nervous system, gut-brain health and mental wellbeing interact across women’s lives.
Scotti discovered her own neurodivergence during perimenopause - the same stage of life when neurodivergence diagnosis peaks in women. This experience later shaped her MSc thesis exploring the relationship between hormonal changes and ADHD, and why menopause can affect some women far more intensely than others.
Through her clinical work and speaking, she advocates for a more informed, compassionate and neuro-affirming understanding of menopause, neurodivergence and the relationship between the brain and body.
How menopause affects the brain
Menopause is often defined by the ovaries: periods become irregular and eventually stop.
But oestrogen and progesterone are not only reproductive hormones. They also act directly on the brain and nervous system.
Oestrogen helps regulate brain energy, mood, temperature control, memory and attention, partly through its influence on brain chemicals such as serotonin, dopamine and acetylcholine.
Progesterone interacts with calming pathways in the nervous system, including GABA - which is one reason shifts in progesterone can be felt through sleep, anxiety, tension and stress sensitivity.
As these hormones fluctuate and decline through the menopausal transition, the brain has to adapt - a process of recalibration. This is why menopause can be felt in the whole body: sleep, temperature, stress response, energy, sensory processing and emotional steadiness are all coordinated through the brain.
Beyond brain fog
While brain fog is often part of the picture, it is not the whole story.
Some women describe losing words, forgetting why they walked into a room or struggling to concentrate. Others feel more anxious, less resilient, more easily overwhelmed or less able to tolerate noise, conflict, pressure or change.
For many, the hardest part is not one symptom. It is the sense that the internal operating system has changed.
This can be especially confusing for women who have always been capable, high-functioning or used to pushing through. What used to work may no longer work in the same way.
When everything feels harder to manage
The effects on the menopausal brain do not exist in isolation.
This brain recalibration is happening alongside real-life pressures: work, caring responsibilities, ageing parents, relationship changes, chronic stress, poor sleep and years of over-functioning.
If the nervous system is already depleted, menopause can feel like the point where coping strategies start to fail. This is not simply about willpower or mindset. It can reflect a real shift in how much demand the system can handle before it becomes overloaded.
How can we nourish the brain through menopause?
The brain depends on the body systems that shape energy, signalling and resilience.
It is also the body’s most energy-demanding organ, with high nutrient needs. It relies on steady fuel, enough protein and healthy fats, key micronutrients, hydration, oxygen, sleep and recovery to function well.
What supports the brain in menopause is often what supports health more broadly: steady blood sugar, enough protein and healthy fats, restorative sleep, regular movement, stress regulation, nervous system support and meaningful recovery.
These systems also influence each other. Poor sleep can make blood sugar less stable the next day. Unstable blood sugar can activate the stress response, which can affect mood, focus and energy. Chronic stress - whether from mental load, under-fuelling, overwork, sensory overload or too little recovery - can then make sleep lighter and recovery harder. This is how one symptom can become a pattern.
Personalised support matters too. The same symptom can have different drivers in different women - hormone shifts, poor sleep, under-fuelling, chronic stress, inflammation, low nutrient status, low muscle mass or long-term pressure on the stress response.
Rather than asking how to quieten one symptom in isolation, the question becomes: what does your whole system need?
What if you are neurodivergent? (+ free workshop!)
For neurodivergent women, this matters because many of the systems affected by hormonal shifts - stress regulation, sensory processing, sleep and executive function - may already require extra effort, structure or recovery time.
Oestrogen also helps regulate dopamine, a brain chemical involved in attention, motivation, reward, executive function and emotional regulation. When oestrogen fluctuates in perimenopause or declines after menopause, dopamine-related systems may feel less stable.
This may help explain why long-standing coping strategies can become less reliable, and why traits that were previously manageable may become more visible or harder to compensate for.
At the same time, neurodivergent women may experience the menopause transition more intensely than many of their peers. For many, this is also the stage of life when they begin to recognise their neurodivergence for the first time. This is not a niche issue. It is a missing part of many women’s health conversations.
In the upcoming MenoMinds Academy session, Scotti McLaren will zoom in on this often-overlooked intersection between menopause and neurodivergence - exploring what may be happening beneath the surface, why coping strategies can change and how a more informed, neuro-affirming approach can help women navigate this stage of life.
Join Scotti to explore neurodivergent menopause with more clarity, compassion and practical understanding.

We are not clinicians and cannot diagnose depression or other mental health conditions. If you’re having thoughts of harming yourself, or you feel like you can’t keep yourself safe, seek urgent help. Contact NHS urgent services, your GP, or a crisis service such as SHOUT (text 85258 in the UK). If you’re in immediate danger, call 999.
Seeking support
If symptoms persist, worsen, or begin to feel overwhelming, it is important to seek professional support. Speaking to your GP can be a helpful first step in understanding what you are experiencing and exploring treatment or support options. We also recognise that not all women feel ready to take this step, or may have had previous experiences that make this difficult.
If you ever feel unable to keep yourself safe, or you are experiencing thoughts of self-harm or suicide, please seek urgent help. You can contact your GP, call NHS 111, or reach out to Samaritans on 116 123 (free, 24/7) or jo@samaritans.org. If you are in immediate danger, call 999 or go to your nearest A&E.
