ADHD and Perimenopause: Why So Many Women Start Struggling in Midlife
Updated: Sep 21
I've started noticing a pattern in my office.
Women are coming to me in their late 30s, 40s, and 50s saying that things that used to feel manageable suddenly don't.
Sometimes they already know they have ADHD and wonder why it feels so much harder to manage. Other times, they're struggling with concentration, memory, anxiety, or overwhelm in ways that make them wonder if they might have ADHD for the first time or worse – dementia.
I have ADHD myself, and my daughter has ADHD, so I've spent a lot of time learning about how ADHD shows up in women. More recently, I've been digging into the research on perimenopause and women's mental health.
And what I'm learning is fascinating.
Many women with ADHD make it well into adulthood without being diagnosed, often after years of developing ways to manage or compensate for their symptoms. Then they enter a hormonal transition that can affect some of the very things they've worked so hard to manage.
Perimenopause didn't suddenly give them ADHD. But for some women, it may be the stage of life when they realize just how hard they've been working to keep their heads above water.
For others, what they're experiencing may be primarily perimenopause, anxiety, depression, or something else entirely.
There's still so much we don't know. But the more I learn, the more convinced I am that we need to stop looking at women's hormonal health and mental health as two completely separate conversations.
Why So Many Women Don't Discover Their ADHD Until Adulthood
ADHD doesn't suddenly develop during perimenopause. It's a neurodevelopmental condition, which means it begins earlier in life, however that doesn't mean anyone recognized it.
For decades, our cultural picture of ADHD was largely the little boy who couldn't sit still in class.
For girls, it may have looked very different.
Maybe she stared out the window.
Waited until the last possible minute to start a project.
Had a chaotic bedroom but great grades.
Forgot things constantly but found ways to compensate.
Sat in her seat, but experienced verbal hyperactivity.
Or became incredibly responsible because she learned early how awful it felt when something slipped through the cracks.
Research has consistently found that ADHD in girls and women is more likely to be missed or recognized later.
By adulthood, many women have developed all kinds of ways to work with, or work around, their ADHD.
Maybe you make lists, set alarms, put everything on the calendar, build routines around the things you know you're likely to forget. Sometimes those systems work really well, and sometimes you still forget things, run late, or feel like you're constantly playing catch-up.
The point isn't that you've figured out how to make your ADHD disappear. It's that you may have spent years putting a tremendous amount of effort into managing it, whether you realized that's what you were doing or not.
Enter Perimenopause and the Strategies That Worked for Years Stop Working
Perimenopause can begin earlier than many women realize, often sometime in the 40s, but sometimes in the 30s. And while we tend to associate it with hot flashes and changes to our periods, the menopause transition can also affect sleep, concentration, memory, mood, anxiety, and our ability to handle stress.
So imagine you've spent years building systems that help you manage your ADHD, whether you knew that's what you were doing or not.
Then you're not sleeping as well, your hormones are fluctuating, your memory feels less reliable, your brain feels foggy, you have less bandwidth.
Maybe, at the exact same time, you're raising children, helping aging parents, managing a career, maintaining relationships, running a household, and carrying a thousand invisible responsibilities.
Suddenly, the strategies you've relied on for years aren't working like they used to.
For a woman with ADHD, diagnosed or not, that can make this stage of life particularly confusing.
Psychiatrist Dr. Sasha Hamdani describes it this way:
“Perimenopause often unmasks ADHD rather than creating it, as the estrogen scaffolding that helped many women compensate starts to slip.” — Dr. Sasha Hamdani
I think the distinction between creating and unmasking ADHD is an important one. Perimenopause didn't give you ADHD. But for some women, it may make patterns that have been there for years much harder to compensate for or ignore.
And this is where some of the emerging research gets really interesting.
In a recent population-based study of more than 5,000 women ages 35 to 55, 54.2% of women with ADHD reported severe perimenopausal symptoms compared with 30.1% of women without ADHD. Even more interesting, symptom scores peaked among women with ADHD at ages 35 to 39, compared with ages 45 to 49 among women without ADHD.
Researchers suggest this could point to women with ADHD experiencing significant perimenopausal symptoms at younger ages.
But I want to make one important clarification here because I can imagine what some women might be thinking:
Does that mean women with ADHD have a fertility window that's 10 years shorter?
There is currently no evidence showing that.
The study measured women's symptoms. It did not measure ovarian reserve, fertility, or the age at which these women ultimately reached menopause. So experiencing more severe symptoms at a younger age does not mean we can conclude that your ovaries are aging faster or that your fertility window is shorter because you have ADHD.
What the emerging research does raise is another interesting possibility: women with ADHD may experience hormonal transitions differently or feel their effects more significantly. Hormonal fluctuations occur well before menopause, and researchers are still working to understand how those changes may interact with ADHD.
There's still a lot we need to learn. But there's enough here that we need to pay attention, ask better questions, and make sure women are getting support for symptoms that can have a very real impact on their lives.
What Does Estrogen Have to Do With ADHD?
Estrogen interacts with several neurotransmitter systems in the brain, including dopamine. Dopamine is relevant to ADHD because it plays an important role in attention, motivation, reward, and executive functioning.
Dr. Jolene Brighten explains the potential connection this way:
“Estrogen is a powerful brain hormone that can boost dopamine. When estrogen drops during perimenopause and menopause, ADHD symptoms can worsen.” — Dr. Jolene Brighten
During perimenopause, estrogen and progesterone don't simply decline in a nice, predictable straight line, hormone levels can fluctuate significantly.
A 2025 systematic review found evidence suggesting that hormonal fluctuations may be associated with changes in ADHD symptoms, particularly around puberty and the menstrual cycle.
If you're experiencing significant perimenopause symptoms alongside changes in your concentration, memory, mood, sleep, or executive functioning, it's worth talking with your OB-GYN or a menopause-trained healthcare provider about your symptoms and whether menopausal hormone therapy might be appropriate for you.
Hormone therapy is an established treatment for certain menopause symptoms, particularly hot flashes and night sweats, and it may also help some women with sleep and mood changes. It has not been established as a treatment for ADHD itself.
But if poor sleep, mood changes, hot flashes, and other perimenopause symptoms are making it even harder for you to concentrate, regulate your emotions, or manage your daily life, treating those symptoms may still make a meaningful difference.
Is It ADHD, Perimenopause, or Both?
Here's where it gets tricky: ADHD and perimenopause can share many of the same struggles.
If these symptoms suddenly appear in your 40s, that doesn't automatically mean you have ADHD.
A good ADHD evaluation looks backward. Were you forgetful as a child? Did you lose things? Daydream? Procrastinate until the last possible second? Has organization always taken more effort than other people realized?
One of the most useful questions we can ask is: "Is this actually new, or has some version of this been here all along?"
For some women, looking backward reveals ADHD that was missed for decades. For others, these changes really are new and may be more closely connected to perimenopause.
And for many women, both may be part of the picture.
What About Anxiety or Depression That Seems to Come Out of Nowhere?
ADHD isn't the only reason I pay attention to hormonal transitions.
Sometimes a woman will sit in my office and say:
"I've never struggled with depression before. Why am I suddenly depressed?"
Or:
"I've always handled stress pretty well. Why am I so anxious now?"
One of the first things I want to know is when it started.
We know that major hormonal transitions can intersect with mental health. Puberty is one. Pregnancy and postpartum are others. Perimenopause is another.
The American College of Obstetricians and Gynecologists (ACOG) notes that the risk of depression increases during the menopause transition and that changes in mood, anxiety, sleep, irritability levels, and concentration can occur during this stage of life.
That doesn't mean new anxiety or depression in your 40s is automatically caused by hormones. But it does mean hormones deserve a place in the conversation.
For many women, it isn't necessarily a question of treating either their mental health or their perimenopause symptoms. They may need support for both.
I don't want a woman with new anxiety at 45 to automatically be told, "It's just hormones." But I also don't want hormones completely left out of the conversation.
Why Haven't We Been Talking About This?
This is the question I keep coming back to as I learn more about perimenopause:
Why didn't I learn more about this?
I'm a psychologist with thirteen years of post-secondary education, and I've had to go looking for much of this information myself. I've been reading the research, attending continuing education, and learning from specialists in women's health. The deeper I go, the more surprised I am by how much we're still learning about female hormonal transitions and mental health.
And I don't think this is because psychologists or physicians don't want to help their patients. Most of us went into these professions because we genuinely do.
The reality is that women's health, and particularly the intersection between hormones, the brain, and mental health, hasn't always received the research or attention it deserves. That means even a thoughtful, well-intentioned provider may not have received extensive training in perimenopause or in how hormonal transitions can intersect with conditions like ADHD, anxiety, and depression.
That's one reason I think it's so important for both providers and patients to keep asking questions as the research evolves.
Our healthcare system can make connecting those dots even harder. A woman may have one provider treating her ADHD, another treating anxiety or depression, and another managing perimenopause.
Meanwhile, she's one person living in one body.
We need to look at the whole picture.
If This Sounds Like You, Start Here
You don't have to figure out whether it's ADHD, perimenopause, anxiety, depression, or something else before asking for help.
Start by paying attention to your timeline.
Ask yourself:
What has changed recently?
What has always been difficult?
How am I sleeping?
Has my menstrual cycle changed?
What's happening with my concentration and memory?
Am I more anxious or irritable?
What systems used to work that aren't working anymore?
When I look back at childhood and early adulthood, do I recognize some of these patterns?
If you're wondering about ADHD, consider talking with a clinician experienced in evaluating ADHD in adult women. A thorough ADHD evaluation should look at your history, not just what you're experiencing today.
If you're experiencing signs of perimenopause, talk with your OB-GYN or a healthcare professional knowledgeable about menopause. And if you're already being treated for ADHD and something has changed, bring that up with the clinician managing your treatment too.
You may need support in more than one area, and that's exactly why looking at the whole picture matters.
Maybe what you're experiencing is primarily perimenopause. Maybe ADHD is part of your story. Maybe anxiety or depression needs attention.
Maybe several of those things are true at the same time.
Sometimes Having Less Bandwidth Changes Your Life
There's another side of this transition that I think is worth talking about.
Sometimes having less bandwidth means you simply can't keep tolerating, accommodating, or carrying as much as you once did.
For a woman with ADHD who may already have spent years working incredibly hard to manage life, that shift can feel especially profound.
But sometimes it can also become a catalyst for getting support and making changes that have been needed for a long time.
Dr. Mary Claire Haver puts it beautifully:
"Menopause often arrives precisely during this transition from caring to freedom. It's not just a physical journey. It's a psychological one too... The hot flashes and brain fog? Temporary. The newfound courage to prioritize yourself? That's the permanent transformation." — Dr. Mary Claire Haver
Maybe the goal isn't simply to get you back to tolerating everything you could tolerate before.
Maybe this stage of life is also an invitation to pay attention to what isn't working anymore, get the support you need, and make changes that allow your life to work better for the person you are now.
Instead of only asking, "What's wrong with me?" I want women to start asking, "What changed, what has been here all along, and what kind of support do I need now?"
The research still has catching up to do. But we know enough to listen when women say:
"Something feels different."
And we know enough to start taking the intersection between women's hormonal health and mental health much more seriously.
Looking for Support?
If you're reading this and thinking, Oh my gosh, this sounds like me, this is an area I've become deeply interested in both clinically and personally.
As a psychologist with ADHD myself, I've spent a great deal of time learning about ADHD in women.
My growing interest in perimenopause has led me to keep digging into the research on hormones, ADHD, and women's mental health.
If you'd like to talk with someone who understands this intersection and can help you make sense of what you're experiencing, feel free to reach out to me about counseling.
