You walk into a room and forget why you came. Maybe, you snap at someone you love. You lie awake at 3am, mind racing, even though you are exhausted. You feel a low-grade irritability that surprises you with its edges, and then feel guilty about it for the rest of the day.
And underneath all of it, a quieter, more unsettling question: Is this just who I am now?
If you are in your late 30s or 40s and these experiences feel familiar, there is a meaningful chance that what you are navigating is perimenopause, specifically the cognitive and emotional dimensions of it that our culture consistently undernames and underserves.
You are not losing yourself. But you deserve to understand what is happening, and you deserve support that takes the whole of your experience seriously.
What Is Actually Happening in Your Brain During ?
Perimenopause is the hormonal transition that precedes menopause, typically beginning in a woman’s late 30s to mid-40s and lasting for several years. During this time, estrogen levels fluctuate significantly before eventually declining.
What most conversations about perimenopause leave out is what estrogen actually does in the brain.
Estrogen receptors are widely distributed throughout the brain, including in the hippocampus and prefrontal cortex, the areas most responsible for memory, focus, decision-making, and emotional regulation. When estrogen levels become unpredictable, as they do during perimenopause, these brain functions are directly affected.
Research published in Advances in Therapy (Springer, 2026) found that cognitive and memory difficulties during perimenopause and menopause affect up to two thirds of women. [1] These difficulties can include confusion, forgetfulness, reduced concentration, difficulty learning new information, and what many women describe simply as feeling slower or less sharp than they used to.
Additional research estimates that between 44 and 62 percent of women experience subjective cognitive decline during the perimenopausal transition. [2] This is not imagined. It is not anxiety. It is a real and documented neurological response to hormonal fluctuation.
And yet the vast majority of women receive no education about this before it happens.
The Mood Dimension: More Than Just Hormones
The physical and cognitive dimensions of perimenopause are significant. But for many of the women I work with near Washington DC, it is the emotional and psychological dimensions that feel most disorienting.
Perimenopause is now recognized by mental health researchers as one of three key windows of vulnerability for women’s mental health, alongside puberty and the perinatal period. T
he dramatic hormonal fluctuations during these phases can make women significantly more susceptible to anxiety, depression, and mood instability, even women who have never experienced these conditions before.
A landmark 2024 study published in Nature Mental Health analyzed data from over 128,000 women in the UK Biobank and found increased rates of first-onset major depressive disorder during the perimenopausal years compared to the premenopausal period. [3]
The Menopause Society states plainly that women who have never experienced depression are two to four times more likely to experience a depressive episode during the menopausal transition. [4]
These are not small increases in risk. They are significant, and they deserve significant attention.
What Perimenopause Can Feel Like Emotionally
Part of what makes perimenopause so difficult to navigate is that its emotional symptoms can be easy to misattribute. Women frequently hear that what they are feeling is stress, burnout, anxiety, or simply the pressures of midlife. These explanations are not wrong. But they are incomplete without the hormonal context.
Here are some of the emotional and psychological experiences that most commonly bring perimenopausal women into my practice:
Mood and emotional reactivity:
- Irritability that arrives quickly and feels disproportionate
- Mood fluctuations that shift faster and more intensely than usual
- Low mood, sadness, or a flatness that is hard to shake
- A heightened emotional sensitivity that surprises you
- Feelings of grief or loss that are difficult to name
Anxiety and cognitive changes:
- Racing thoughts or difficulty quieting the mind
- A persistent low-level worry that something is wrong
- Difficulty concentrating, following conversations, or completing tasks
- Forgetfulness, misplaced words, or a frustrating inability to retrieve information
- A sense of mental fog that makes simple things feel effortful
Identity and sense of self:
- Feeling unfamiliar to yourself, as though you have become someone you do not quite recognize
- Questioning who you are outside of the roles you have built your life around
- A growing awareness of things you have set aside, parts of yourself, desires, needs, values, that are beginning to ask for attention
- Grief over the changing chapter of your reproductive life, even if you did not expect to feel it
The Part That Often Goes Unspoken
There is something that many of the women I work with eventually name, often quietly, often with some relief at finally saying it out loud.
They do not just feel different physically. They feel like they are losing themselves.
The version of themselves that was capable, composed, sharp, and able to manage everything is becoming less reliable. And in a culture that has consistently told women to hold everything together, that loss of perceived capability can be profoundly frightening.
What I want you to know is this: you are not losing yourself. You are in a profound biological and ps
ychological transition, one that asks enormous things of your body, your brain, and your sense of identity simultaneously.
The disorientation you are feeling is real. It is also navigable, with the right support.
How Therapy Can Help
Evidence-based therapy has a meaningful and growing research foundation for supporting women through the perimenopausal transition. A 2024 meta-analysis of 30 randomized controlled trials published in the Journal of Affective Disorders found that Cognitive Behavioral Therapy
significantly improved mood symptoms, cognitive functioning, and quality of life
in menopausal women. [5] The North American Menopause Society supports CBT as a first-line non-hormonal treatment option for both physical and psychological menopausal symptoms.
But therapy during perimenopause offers more than symptom management. It offers a space to hold the full complexi
ty of this season of life.
In our work together, I can support you in:
- Understanding the hormonal dimension of what you are experiencing, so you can stop blaming yourself for feelings that have a real biological basis
- Developing
tools for managing anxiety, emotional reactivity, and the cognitive symptoms that are disrupting your daily life - Exploring the identity shifts that perimenopause often invites, including the quieter questions about who you are becoming and what you want this next chapter to hold
- Processing grief, including any grief over your changing reproductive status, shifts in your relationships, or the evolving landscape of midlife
- Strengthening your relationship with yourself at a time when that relationship is being asked to grow and change
You Are Still Becoming
Perimenopause is not the end of something. It is, for many women, the beginning of one of the most honest and clarifying chapters of their lives.
But getting there, from disoriented to grounded, from anxious to present, from feeling unlike yourself to finding yourself again, often requires support that honors the full depth of what you are going through.
I am here for that.

Frequently Asked Questions About Perimenopause Brain Fog and Mood Therapy
What causes brain fog during perimenopause?
Brain fog during perimenopause is primarily caused by fluctuating and declining estrogen levels. Estrogen plays an important role in brain health, including memory, focus, and mood regulation. Research estimates that between 44 and 62 percent of women experience subjective cognitive decline, including forgetfulness, word-finding difficulties, and difficulty concentrating, during perimenopause.
Is perimenopause linked to anxiety and depression?
Yes. A landmark 2024 study in Nature Mental Health analyzing data from over 128,000 women found increased rates of first-onset major depressive disorder during perimenopause. The Menopause Society notes that women who have never experienced depression are two to four times more likely to experience a depressive episode during the menopausal transition.
How long does perimenopause brain fog last?
Research suggests that brain fog during perimenopause can last up to three years as estrogen and progesterone fluctuate. For most women, cognitive symptoms improve after the transition is complete. The psychological weight of these changes, however, often benefits significantly from therapeutic support during the transition itself.
Why am I so irritable during perimenopause?
Irritability during perimenopause is primarily driven by hormonal fluctuations, particularly changes in estrogen, which affect the brain’s regulation of mood and emotional reactivity. Sleep disruption compounds this significantly. Many women are surprised by the intensity of their irritability, and therapy can provide meaningful support for both the emotional experience and its impact on relationships.
Is it perimenopause or anxiety?
Often, it is both. Anxiety is one of the most common psychological symptoms of perimenopause, driven by the same hormonal fluctuations that produce other perimenopausal symptoms. Working with a therapist who understands the intersection of reproductive health and mental health can help you understand what you are experiencing and receive support that addresses the whole picture.
Can therapy help with perimenopause symptoms?
Yes. A 2024 meta-analysis of 30 randomized controlled trials found that CBT significantly improved mood, cognition, and quality of life during the menopausal transition. The North American Menopause Society supports CBT as a first-line non-hormonal treatment option. Therapy also addresses the identity and relational dimensions of this transition that go beyond symptom management.
Do you offer perimenopause therapy near Washington DC?
Yes. I offer specialized perimenopause therapy in person at my Bethesda, Maryland office and via telehealth throughout Washington DC, Maryland, Virginia, and South Carolina. A free 20-minute consultation is a gentle, no-pressure first step.
