The incomplete story of menopause
For decades, menopause was presented as a simple hormonal event. A reproductive change. A "natural step." A matter of hot flashes, irregular cycles, and aging.
That view is profoundly reductionist.
Menopause doesn't just affect the ovaries. It affects the brain, the nervous system, sleep, emotional regulation, sense of identity, memory, cognitive ability, resilience to stress, the relationship with one's own body, and the sense of continuity of self.
And yet, millions of women go through this process without adequate information, without serious clinical support, and above all, are constantly invalidated.
“You’re sensitive.” “It’s your age.” “Everyone goes through it.” “It’s psychological.”
Let's be clear: what you're experiencing goes far beyond the "psychological." The menopausal transition involves a profound neuroendocrine reorganization that directly impacts your mental health and brain function. And the magnitude of that impact has been systematically underestimated.
The menopausal brain: a real neurobiological transition
One of the most frequent mistakes is thinking that estrogens only serve reproductive functions.
Estrogen is also a brain molecule.
Your brain is full of estrogen receptors, especially in regions involved in memory, emotional regulation, attention, sleep, stress, motivation, and executive function.
Neuroscientist Lisa Mosconi (2024) has shown, through neuroimaging studies, that menopause produces real metabolic changes in the female brain. Not metaphorical. Real and measurable.
Neuroimaging studies show decreased brain glucose metabolism, changes in neuronal connectivity, alterations in regions associated with memory and attention, increased neuroinflammation, and alterations in serotonergic and dopaminergic systems.
Your brain is literally adapting to a new hormonal reality. And that adaptation consumes resources.
Perhaps during this period you will recognize the mental fog, the difficulty concentrating, the loss of verbal fluency, frequent forgetfulness, cognitive fatigue, the feeling of "not being the same".
The problem is that culturally we continue to interpret these symptoms as personal weakness, instead of recognizing them as part of a complex neurobiological transition.
Estrogen, serotonin, and emotional regulation
Estrogen is directly involved in the regulation of neurotransmitters that are fundamental to mental health: serotonin, dopamine, GABA, noradrenaline.
When hormone levels fluctuate intensely, especially during perimenopause, the nervous system loses regulatory stability.
And here's one of the most important points. The anxiety or depression that may appear at this stage doesn't arise "out of nowhere." What happens is that your brain loses some of the neuroprotective modulation that estrogen provided.
The result may include intense anxiety, extreme irritability, emotional hypersensitivity, panic attacks, hopelessness, anhedonia, and a feeling of permanent dysregulation.
Neuropsychiatrist Louann Brizendine (2022) describes how hormonal fluctuations directly alter the brain's emotional circuits. It is no coincidence that many women experience significant psychiatric symptoms for the first time in their lives during the menopausal transition.
The nervous system becomes vulnerable
Menopause also profoundly alters the autonomic nervous system.
Estrogen plays a role in regulating cortisol, vagal flexibility, inflammation, the stress response, body temperature, and restorative sleep. When estrogen levels decline, the body becomes less physiologically resilient.
And this radically changes how you experience the world. Suddenly, you tolerate stress worse, overstimulation exhausts you, mental noise increases, recovery becomes slower, and emotions affect you more intensely.
You may feel like you're "losing tolerance." What's really happening is that your nervous system has less physiological buffering capacity.
And here an extremely important phenomenon emerges: menopause often uncovers old imbalances that the body had managed to compensate for over the years. Unprocessed traumas. Chronic overload. Hypervigilance. Self-neglect. Excessive demands. Exhausting relationships.
Your body can no longer sustain the same level of silent compensation. Menopause doesn't necessarily create all the problems, but it does eliminate many of the biological strategies that allowed it to hide them.
Sleep: the hidden epicenter of the crisis
One of the most devastating factors for mental health during menopause is impaired sleep. And the problem is vastly underestimated.
Hormonal imbalances affect melatonin, body temperature, nighttime cortisol, sleep architecture, and REM sleep. The result is fragmented, shallow, and unrefreshing sleep.
This has massive neuropsychological consequences. Neuroscientist Matthew Walker (2017) extensively documented how sleep regulates the amygdala, emotional memory, prefrontal control, brain inflammation, and emotional resilience.
When your sleep collapses, anxiety increases, emotional regulation decreases, memory worsens, impulsivity increases, the perception of threat increases, and metacognitive ability decreases.
You may have been chronically sleep-deprived for years without receiving proper intervention. And then you wonder why you feel like you "can't take it anymore." Your brain can't function properly without nighttime repair. There's no sophisticated emotional regulation on an exhausted nervous system.
Silent inflammation and the brain
Another key aspect is the relationship between menopause and inflammation.
The decline in estrogen alters metabolism, the microbiome, the immune response, and systemic inflammation. And a growing body of research shows that inflammation and mental health are deeply interconnected. Psychiatrist Edward Bullmore (2018) has synthesized this line of research by describing the role of inflammation in depression.
Neuroinflammation affects motivation, energy, cognition, mood, and mental clarity.
You might recognize a kind of "internal shutdown" during menopause. It's not always classic depression. Sometimes it's physiological inflammation impacting your brain function.
This is greatly exacerbated by chronic stress, overwork, isolation, ultra-processed foods, sedentary lifestyles, sleep deprivation, and digital overstimulation. Modern society is structured in precisely the opposite way to what a menopausal nervous system needs to regulate itself.
The psychological dimension: the collapse of adaptive identity
Menopause goes beyond biology. It's also about identity. And here we arrive at a much deeper and less discussed dimension.
You may experience a major psychological breakdown at this stage, because the identity structures you've maintained for decades are no longer viable. Extreme complacency. Hyper-adaptation. The constant caregiving role. Self-imposed demands. Disconnection from your body. The need for approval.
Your body begins to reject what it once tolerated. And this produces a real existential crisis.
You may discover at this stage an accumulated exhaustion of decades, deeply unbalanced relationships, loss of authenticity, repressed resentment, chronic emotional disconnection.
Menopause often acts as a biological process of truth. The body ceases to cooperate with certain forms of self-neglect.
Insufficient medicalization and clinical abandonment
Another huge problem is the medical void surrounding menopause.
For years, millions of women were misdiagnosed, incorrectly psychiatrized, medicated without addressing hormonal causes, and clinically ignored.
You may have received antidepressants when the core problem also included hormonal deficiency, inflammation, disrupted sleep, autonomic dysregulation, and physiological exhaustion.
This doesn't mean that psychiatric treatments don't help in some cases. But reducing the entire menopausal experience to "depression" is clinically inadequate. Menopause requires an integrative approach: endocrine, neurological, psychological, metabolic, relational, and somatic.
What changes when you understand what's happening
One of the most damaging things about menopause is the feeling of losing yourself without understanding why.
When you understand that your brain is going through a reorganization, that your nervous system needs new conditions, that your sleep is no longer negotiable, that your stress capacity has changed physiologically, that your body requires a different regulation, something important happens: you stop interpreting yourself as defective.
And that completely changes your relationship with the process. Because menopause goes far beyond decline. It's a neurobiological, psychological, and existential transition. It can become a breakdown, or a profound reorganization.
Many women describe experiencing greater clarity, less tolerance for falsehood, more authenticity, stronger boundaries, a greater connection to their bodies, and less need for external validation after going through it. It's as if the nervous system stops supporting identities constructed for survival.
Menopause is not the end of vitality
The problem isn't menopause itself. The problem is going through it uninformed, exhausted, inflamed, overstressed, sleep-deprived, disconnected from your body, and without adequate support.
Your body isn't failing. It's entering another biological phase that requires new conditions of regulation and care.
And the more you understand the relationship between hormones, brain, nervous system and mental health, the less you will experience this stage believing that you are losing yourself.
Because often what's really disappearing isn't your deepest identity. It's the exhausted structure that's been working against your body for years.
