“I Don’t Feel Like Myself”: Can Perimenopause Affect Your Mental Health?
Written by Holley Hillis, MSN, PMHNP-BC
Maybe nothing dramatic happened.
Your life looks mostly the same. You're still working, taking care of your family, managing the house, keeping up with responsibilities, and doing the things you've always done.
But lately, something feels different.
You're more irritable than you used to be.
Small things overwhelm you.
You're waking up at 3 a.m. and can't get back to sleep.
Your anxiety suddenly feels louder.
You're forgetting words, losing your train of thought, or walking into a room and wondering why you're there.
Maybe you've even found yourself thinking:
“I just don't feel like myself anymore.”
For some women, changes like these can be part of the transition into perimenopause.
Mental health symptoms don't get nearly as much attention as hot flashes and changing periods, but mood changes, sleep difficulties, problems with concentration, and increased vulnerability to depression can occur during the menopause transition.
And sometimes those changes begin before a woman realizes she's entering perimenopause at all.
What Is Perimenopause?
Perimenopause is the transition leading up to menopause.
During this time, ovarian hormone production becomes more variable. Estrogen and progesterone don't simply decline in a smooth, predictable line. They fluctuate, sometimes considerably, as the body moves toward menopause.
Eventually, menstrual periods stop. Menopause itself is reached after 12 consecutive months without a menstrual period, assuming there isn't another reason for the absence of periods.
But the transition leading up to that point can last for years.
And although changing menstrual cycles and hot flashes may be the symptoms people associate most strongly with perimenopause, they aren't the only things women may experience.
Mood can change too.
What Can Perimenopause Feel Like Mentally?
There isn't one universal perimenopause experience.
Some women move through the transition with relatively few psychological symptoms. Others notice significant changes.
You might experience:
increased anxiety or worry
irritability or a shorter temper
feeling emotionally overwhelmed more easily
tearfulness
lower mood
decreased motivation
difficulty concentrating
forgetfulness or “brain fog”
sleep problems
feeling less resilient to stress
worsening of an existing mental health condition
ACOG notes that about 4 in 10 women experience mood symptoms during perimenopause that can resemble PMS, including irritability, low energy, tearfulness, moodiness, and difficulty concentrating. Unlike traditional PMS, however, these symptoms may not follow a predictable monthly pattern.
That's part of what can make the experience so confusing.
You may not be able to point to one obvious cause.
You just know that something feels different.
Why Can Perimenopause Affect Mental Health?
The answer is probably more complicated than “your hormones are changing.”
Hormonal fluctuations during the menopause transition may influence brain systems involved in mood and emotional regulation. Some women appear to be particularly sensitive to reproductive hormonal changes, and the risk of depression increases during the menopause transition, especially among women with a previous history of depression.
But hormones aren't happening in isolation.
Think about what else may be happening during this stage of a woman's life.
You may be:
raising children or teenagers,
helping young adult children leave home,
caring for aging parents,
managing a demanding career,
navigating relationship changes,
experiencing changes in your own health,
or somehow doing several of those things at once.
ACOG specifically points out that the pressures common during the 40s and 50s can compound the mental-health challenges occurring during perimenopause.
So when a woman says, “I don't know why I can't handle things the way I used to,” I don't think the most useful answer is automatically:
It's your hormones.
But I don't think we should automatically say:
You're just stressed, either.
We need to look at the whole picture.
Sleep May Be a Bigger Part of the Story Than You Realize
Sometimes women notice the emotional changes before they notice just how much their sleep has changed.
Maybe you're falling asleep normally but waking repeatedly.
Maybe night sweats are disrupting your sleep.
Maybe you wake up much earlier than you used to.
Or perhaps your brain simply decides that 3:17 a.m. is an excellent time to review every problem you've encountered since 2009.
Poor sleep doesn't stay contained to nighttime.
Sleep disruption can affect concentration, memory, decision-making, emotional regulation, and our ability to cope with stress. Menopause-related sleep disruption can therefore contribute to feeling cognitively and emotionally unlike yourself during the day.
That's why sleep is something I want to know about when evaluating changes in someone's mental health.
What About “Brain Fog”?
This one can be frightening.
A woman who has always been sharp suddenly can't remember the word she wants.
She walks into a room and forgets why.
She has trouble concentrating during a meeting.
She's rereading the same paragraph three times.
And naturally, she starts wondering whether something is seriously wrong.
Difficulty concentrating and subjective memory changes are commonly reported during the menopause transition. Sleep problems and mood symptoms can also contribute to cognitive difficulties. The Menopause Society notes that the typical cognitive changes experienced around midlife tend to be subtle and are not the same thing as dementia.
That doesn't mean every cognitive symptom should automatically be blamed on perimenopause.
New, significant, rapidly worsening, or otherwise concerning cognitive changes deserve medical evaluation.
But mild changes in concentration and memory during this transition aren't unusual.
Can Perimenopause Cause Anxiety?
Anxiety can emerge or become more noticeable during this transition for some women.
You may notice:
more worrying,
feeling physically keyed up,
difficulty shutting your mind off,
greater sensitivity to stress,
panic symptoms,
or anxiety that seems disproportionate to what is actually happening.
Hormonal shifts, disrupted sleep, physical symptoms such as unpredictable hot flashes, and life stress may all contribute. ACOG recommends talking with a healthcare professional when anxiety is new, worsening, difficult to control, or interfering with everyday life.
And importantly, having anxiety during perimenopause doesn't necessarily mean perimenopause is the only cause.
An anxiety disorder can develop during this period too.
That's why assessment matters.
What About Depression?
This deserves particular attention.
Research consistently suggests that vulnerability to depression increases during the menopause transition, and women with a previous history of depression may be especially vulnerable.
Depression can look like sadness or frequent crying.
But it can also look like:
“I don't enjoy anything anymore.”
“Everything feels like work.”
“I don't want to see anyone.”
“I feel numb.”
“I can't motivate myself to do things.”
“I'm exhausted all the time.”
“I don't recognize myself.”
If those symptoms are persistent or interfering with your ability to function, they deserve evaluation rather than simply being dismissed as something every woman has to tolerate during menopause.
Is It Perimenopause, or Is It Something Else?
This is one of the most important questions.
Because turning 40 does not make every new symptom hormonal.
Changes in mood, concentration, energy, and sleep can occur with many conditions, including:
depression
anxiety disorders
ADHD
thyroid disorders
anemia or nutritional deficiencies
medication effects
substance use
chronic stress
sleep disorders
other medical conditions
And sometimes more than one thing is happening.
A woman may have an anxiety disorder and be entering perimenopause.
Someone with ADHD may find that symptoms she previously compensated for become harder to manage.
A woman with a history of depression may experience a recurrence during the menopause transition.
This is why good care shouldn't begin with deciding that hormones are either responsible for everything or nothing.
It should begin with curiosity.
Should I Track My Symptoms?
Yes. Especially when you're having difficulty figuring out what's changing.
You don't need an elaborate spreadsheet.
For several weeks, consider keeping track of:
mood
anxiety
irritability
concentration
sleep
energy
menstrual bleeding
hot flashes or night sweats
medications
significant stressors
ACOG even provides a menopause symptom tracker that includes mood changes such as depression, anxiety, irritability, and mood instability alongside physical symptoms.
The goal isn't to become hyperfocused on every fluctuation.
It's to give yourself and your healthcare providers better information than:
“I don't know. I just haven't felt right lately.”
Sometimes putting several weeks of symptoms on paper makes a pattern much easier to see.
What Can Treatment Look Like?
There isn't one universal “perimenopause mental health treatment.”
Treatment depends on what you're actually experiencing.
For some women, treating an underlying depression or anxiety disorder may be appropriate.
Psychotherapy may be helpful.
Sleep problems may need attention.
Lifestyle changes can support mental and physical health.
For some women, menopause-specific treatment may also be part of the discussion. Hormone therapy can be appropriate for certain menopause symptoms and certain patients, while antidepressants and other nonhormonal treatments may also have a role depending on the symptoms being treated. Current guidelines emphasize individualized treatment and shared decision-making rather than a one-size-fits-all approach.
This is also an area where collaboration matters.
Your psychiatric provider may address depression, anxiety, ADHD, sleep, and psychiatric medications.
Your OB/GYN or menopause clinician may evaluate the broader menopause transition and discuss hormonal and nonhormonal treatment options.
Your primary-care provider may need to evaluate other medical contributors.
Those pieces don't have to compete with each other.
Sometimes the best care involves putting them together.
You Don't Have to Just “Push Through It”
There is a tendency to treat women's transitions as things we're simply supposed to tolerate.
Periods hurt? That's being a woman.
Pregnancy is difficult? That's pregnancy.
Postpartum is overwhelming? That's motherhood.
Can't sleep, can't concentrate, anxious and irritable in your 40s?
Welcome to perimenopause.
But “common” and “not worth treating” are not the same thing.
If something has changed enough that you're thinking:
“I don't feel like myself anymore,”
that's worth paying attention to.
You don't need to diagnose yourself first.
You don't have to determine whether it's hormones, anxiety, depression, ADHD, sleep, stress, or some complicated combination of them.
And you don't have to wait until you're barely functioning before asking for help.
Sometimes the first step really is as simple as saying:
“Something has changed, and I'd like to understand why.”
Frequently Asked Questions
Can perimenopause cause anxiety even if I've never had anxiety before?
Some women report new or increased anxiety during the menopause transition. Hormonal changes, sleep disruption, physical menopause symptoms, and life stress may all contribute. New or significant anxiety should still be evaluated rather than automatically attributed to hormones.
At what age does perimenopause usually start?
The timing varies considerably between women. Changes often begin during the 40s, although menopause-related changes can occur earlier. If you're experiencing symptoms that could suggest an early menopause transition, discussing them with your healthcare provider is appropriate.
Can perimenopause cause brain fog?
Difficulty concentrating and subjective memory changes are commonly reported during the menopause transition. Sleep difficulties and mood symptoms can also affect cognitive functioning. Significant or concerning cognitive changes should be medically evaluated.
Can perimenopause make existing depression or anxiety worse?
It can. The menopause transition appears to be a period of increased vulnerability to depression, particularly for women who have experienced depression previously. Existing anxiety or other psychiatric symptoms may also feel different during this transition.
Do I need a psychiatrist or an OB/GYN for perimenopause-related mental health symptoms?
Sometimes both can be useful. An OB/GYN or menopause clinician can evaluate menopause-related symptoms and discuss menopause treatments, while a psychiatric provider can evaluate and treat conditions such as depression, anxiety, ADHD, and sleep-related psychiatric concerns. Collaborative care can be particularly valuable when symptoms overlap.
