Is this perimenopause or ADHD, and why do women say their ADHD meds stopped working?

The system worked for fifteen years. Then it did not.

The short answer

Women with ADHD describe a specific sequence: medication that used to buy a clear window of focus starts buying a shorter and shallower one, the coping systems built on top of it fail at the same time, and it begins in the late thirties or early forties, before anyone has said the word perimenopause. Others describe the reverse, a lifetime of unrecognised ADHD that perimenopause exposes. The honest answer from the women living it is frequently both. Which one it is for you is a question for the people who prescribe your medication and the people who know your hormones, and the most useful thing this page can do is give you the words to put them in the same conversation.

There is a post in r/adhdwomen with more than twelve hundred upvotes, and the sentence that carries it is four words long.

No one bothered to look.

She was 43. Her ADHD had been managed for years. Then, around 37, it was not:

that was when my ADHD symptoms got so much worst.

Each time she went back, the answer was her ADHD medication. Nobody checked her hormones.

I was exhausted all the time.

That post scored 1,211. Its title began Women with ADHD can experience perimenopause, and it was posted in a community for women with ADHD, not in a community for perimenopause.

Is this perimenopause or ADHD?

Whether it is perimenopause or ADHD is a question the women living it most often answer with both, and it is hard to settle because the two share a surface. Trouble holding a thread, losing the word, losing the keys, losing the afternoon, a rage that arrives from nowhere and leaves the same way: each is on the ADHD list and on the perimenopause list, and a woman with one of them in her history reaches for the familiar explanation first. Nobody on a web page can tell her which it is; what this page can do is describe the three directions the traffic runs, because recognising her road is what gets her to the right appointment.

The question gets asked in exactly this form, as a multiple choice:

This rage, it comes on so quickly and disappears so quickly. It's so intense and I end up crying afterwards. Is it: A. ADHD B. Perimenopause C. Both

That post scored 93 in r/adhdwomen. The top reply, at 21:

OHMYGOD ITS C!!! It's C!! IT IS C!!

The first direction: she has ADHD, and it stops being managed. Diagnosed, treated, stable for years. Then the medication feels weaker, the systems built on top of it fail, and the first explanations offered are stress, depression, or more of the same.

I'm pretty sure I started Peri around 37 yo. That's when nothing worked anymore. My meds stopped working, I could FEEL the cognitive decline impacting the smallest things; it was taking me longer to understand MOVIES details and plots. I was terrified, ADHD and Alzheimer runs in my family.

That is from r/adhdwomen, 385 points.

The second direction: she has never been diagnosed, and perimenopause removes the thing that was hiding it. A lifetime of coping, built so well that nobody noticed, including her. Then the margin goes.

I was recently clinically diagnosed with ADHD, Autism and PMDD after hitting perimenopause early. My insomnia, sensory sensitivities and anxiety had gotten so bad that I stopped going outside altogether.

She was 35. That post scored 214 in r/AuDHDWomen. The same story at 5 points in r/AskWomenOver30, in one line: "At 37 I felt like I was having a nervous breakdown. Ended up being formally diagnosed with ADHD."

The third direction is C. A comment at 45 points in r/adhdwomen: "Recently diagnosed at 38 and i think perimenopause is what makes it worst." The two are not competing explanations. They are often the same woman.

Why does my ADHD medication feel like it stopped working?

ADHD medication that feels like it stopped working is described, with unusual consistency, as medication that still does something but buys a shorter and shallower window: the morning still arrives, the afternoon no longer does. The coping stack that sat on top of the medication fails at the same time, and that is the part women say frightens them, because the stack was the thing they were proud of. Why it happens is a question for the prescriber, with her cycle history in the room; what this page can report is what women say it is like and when they say it began.

most of the coping mechanisms, tips, and tricks that I have taught myself in order to combat my ADHD symptoms, are no longer working. Every day it's harder and harder for me to mask

That is r/adhdwomen, 13 points, and it is the plainest statement of the thing as it is lived.

The claim that it arrives earlier for women with ADHD circulates just as widely. The most upvoted version of it in r/Perimenopause, at 699 points with 102 comments, has this title:

A recent study found that women with ADHD experience more severe perimenopause symptoms starting at a younger age than non-ADHD women.

We have not read the study that post refers to, so this page reports the post, not the study. The same idea as a title, "Perimenopause hits ADHDers earlier", scored 535.

What our own corpus can say about age is narrower: in the surrounding communities the ages women state cluster at 38 and 40, which is who is writing, not how common anything is. The "too young" wall has its own page.

Which doctor do I talk to about perimenopause and ADHD?

The doctor to talk to about perimenopause and ADHD is both of them, together, because the problem women describe is structural rather than medical. The ADHD is managed by one clinician. The hormones, if anyone is managing them, are managed by another. Neither is asking about the other's half, and the woman in the middle is the only person who can see both.

Before anyone names it, she is most often sent toward therapy, then depression, then her thyroid. In the surrounding communities, ADHD comes fourth in that order. The 385-point post above describes the search: "psychiatrists, gynecologists, endocrinologists, even my freaking therapist." What it found: "Turns out there is no exam to evaluate perimenopause."

She almost always works it out herself — from a community, a podcast, a friend or her mother. Rarely from a clinician. That same woman, when she raised it: "Addressed my doctor about it, and was obviously dismissed. Got the whiny woman treatment."

Whether hormone therapy belongs in her plan, and whether her ADHD treatment needs reviewing in the light of it, are both questions for the people who prescribe each of them, with her full history; this page is about how that conversation goes. Nothing about any medication gets decided on the strength of a web page.

What can I do about perimenopause and ADHD this week?

What she can do about perimenopause and ADHD this week is rebuild the scaffolding, which is the part of the problem that is hers, and arrive at the appointment with data.

Log it before you try to explain it

Two cycles of data does more in an appointment than any sentence. Once a day: focus out of ten, hours slept, where you are in your cycle, and when you took what you take. That last column is a record, not a change. What you are looking for is whether the bad days cluster in one part of the month, because a pattern on a page is harder to wave away than a feeling, and it tells two clinicians the same story at once.

Fix the sleep before judging the focus

Coaching practice treats sleep as upstream of everything on this page, so the wake time gets fixed for fourteen days before any conclusion is drawn about attention. The second-half-of-the-night waking that perimenopause specialises in is its own page, and the levers there, alcohol timing, room temperature, morning light, are the ones to pull first.

Rebuild the scaffolding for less margin

The coping stack that failed was built by a woman with more capacity than she has this year. That is not a verdict on her; it is an engineering problem. The rebuild usually runs toward fewer, heavier structures: one list, in one place, not five; the day planned the night before, on paper, because paper has no notifications; work in fixed blocks with a timer she can hear, and a stop at the end of the block whether or not the thing is finished. Working alongside another person, in the room or on a call, which ADHD communities call body doubling, is worth keeping. The brain fog page has the rest, including protecting the one hour of the day when the brain still works.

Eat on a clock, not on appetite

A two-week test: real protein at breakfast, and something at midday whether or not she is hungry, and see whether the afternoon cliff moves. Women on medication that blunts appetite often describe skipping lunch without noticing, and the afternoon that follows is easy to blame on the medication alone. The protein page covers how much and when.

Lift, and walk, and keep it boring

Strength training twice a week and a daily walk are the two training levers coaching practice reaches for first here. Neither needs to be impressive. Both need to be regular, and regular is the ADHD problem, which is why the session goes in the diary as an appointment rather than an intention.

When is it not perimenopause or ADHD?

It is not perimenopause or ADHD, and not something to wait on, when any of the following is true. Take this part seriously rather than politely, and take it first.

Then the ordinary suspects, which are cheap to rule out and produce exactly this picture: thyroid problems, low iron or ferritin, sleep apnoea, depression, and the side effects of anything begun recently.

And the reverse case, which appears in these communities too. A woman in r/Anxiety, at 36 points: "Initially thought I had perimenopause but my anxiety was heightening literally everything." Perimenopause is sometimes the thing she is assuming while the answer is something else. The request is the same in every direction: put it on the list, and look.

What do I actually ask for?

What she asks for is a look at the other half, which is all the woman with 1,211 upvotes was asking for. It does not have to be A or B before she is allowed to ask. The question to walk in with is not which is it, which invites a guess, but are both of these on the list, which invites a process.

Questions women ask about this

Can perimenopause make ADHD worse?

That is what a large number of women with ADHD describe, and it is a description rather than a finding. In the posts we read, focus trouble put in ADHD terms came up 2,073 times, and the perimenopause community has a post flair of its own for it. What they report is a sharp drop in the focus they used to have, coping systems failing, and medication feeling weaker, usually arriving in the late thirties or early forties. Whether that is what is happening to any one woman is for her clinicians to work out.

Why does my ADHD medication feel like it stopped working?

The description women give is consistent: the medication still does something, but the window is shorter and shallower, and the day falls apart earlier. The coping systems built on top of the medication tend to fail at the same time, which is often the part noticed first. Why that happens, and what if anything follows from it, is a conversation with the person who prescribes it, with your cycle history on the table.

Can perimenopause be mistaken for ADHD, or the other way round?

Both directions appear in the posts we read. Women with a long-standing ADHD diagnosis describe being treated for ADHD alone for years while nobody looked at their hormones. Women with no diagnosis describe perimenopause stripping away the coping that had hidden their ADHD, and getting assessed at 38 or 43 or 47. And a smaller set describe assuming perimenopause when the answer turned out to be anxiety or a thyroid problem. The useful move is to ask for both to be on the list rather than to guess which.

Does perimenopause start earlier if I have ADHD?

That claim circulates widely in the ADHD communities, usually with a range of 35 to 40 attached, and the most upvoted version of it in the perimenopause community is a post about a study we have not read, so this page does not vouch for the study. What our own corpus shows is narrower: in the surrounding communities, including the ADHD ones, the ages women state cluster at 38 and 40, and the ages they give for when it began run from 33 to 37. That tells you who is writing, not how common anything is.

Should I see my psychiatrist or my gynaecologist first?

Whichever you can get to first, with one request: that they talk to each other. The pattern women describe is each clinician treating their own half, the ADHD prescriber adjusting ADHD treatment and nobody checking hormones, or a gynaecologist who does not ask about the ADHD at all. The sentence that moves it is a request for a process rather than a diagnosis: I would like perimenopause on the list alongside the ADHD, and I would like whoever manages each of them to know about the other.

Will hormone therapy fix my focus?

Some women in these communities say it changed everything for their ADHD, and at least one in the posts we read says it did basically nothing for hers. That is a conversation for a clinician who knows your history and your other medication. More Herself is a coaching company and does not advise on medication of any kind. The practical levers on this page are worth pulling regardless of what you and your clinicians decide, because they work on a different part of the problem.
