Our Brains, Our Periods & the Things Nobody Told Us
**A Quick Note For the Teens: The bolded “Things Nobody Told You” are your shortcut. The rest of this article is written mostly for the grown-ups who love you and are trying to understand your brain a little better. You are absolutely welcome to read the whole thing, but if your ADHD brain makes it approximately 47% through and wanders off to learn whether penguins have knees, I get it.
For a girl who already has a brain that says “I will absolutely do this thing… eventually, probably… wait, what was I doing?” her period can add another variable to a mind-body system that is already working really hard.
There are a lot of things we ask teenage girls to remember. Homework. (Which has 47 steps in and of itself.) Practice…put your uniform in the wash…bring your shinguards with you…don’t lose your water bottle, hoodie or phone. That they have to be somewhere at 4:15, not 4:45. To text their parent back. To charge their phone. To shower. To wear deodorant. To put the clean laundry away instead of creating a second, slightly more organized version of the floor.
And, somewhere in the middle of all of that: remember that you are going to get your period. Remember when it is coming. Remember to bring supplies. Remember to change them. Remember to bring more supplies. Remember that you put the emergency supplies in the other backpack. Remember that your period is not, in fact, going to pause itself because you have a volleyball game.
The thing nobody told you: If the task is boring, uncomfortable, and happening in private, it may be competing for attention against literally everything else in the universe.
We tend to talk about ADHD as though it lives in the brain and menstruation happens in the uterus, like they function independently. But the brain and body are in constant communication. Hormones, pain, fatigue, hunger, stress—all of it sends information to the brain, and research shows measurable changes in brain activity and connectivity across the menstrual cycle. One study, for example, found changes in brain activity and connectivity across the cycle.
For an ADHD brain, there’s an important wrinkle: the thing that gets your attention isn't always the thing that matters most. Interesting gets attention. Urgent gets attention. Novel gets attention. Uncomfortable definitely gets attention. And when a period adds changes in pain, energy, mood, sleep, or appetite, those signals may suddenly be competing for that same attention.
The sudden realization that you absolutely need to know whether penguins have knees? Strangely compelling. Remembering to change your pad in 20 minutes? Maybe not so much.
The thing nobody told you: The thing that gets your attention isn't always the thing that matters most. Sometimes that’s ok, and sometimes that’s gonna cause problems.
It isn't just about remembering to pack tampons.
Cramps. Bloating. Headaches. Fatigue. Mood changes. Brain fog. Breakouts. Finding a bathroom when you need one. And somehow managing all of it without accidentally leaving the house wearing the emotional equivalent of a giant blinking sign that says I HAVE A PERIOD.
For a brain already managing working memory, time management, organization, task initiation, and attention regulation, that's a lot of moving parts. Just writing this makes me want to take a nap.
This is one of the places where the phrase “Why don't you care?” can do real damage.
A girl may care very much about being clean, being prepared, doing well at school, or avoiding an embarrassing period accident. She may simply have trouble turning that caring into action. Those are not the same thing.
The thing nobody told you: A task can matter deeply to you and still be incredibly difficult to initiate. This is not your fault and it is not a character flaw.
Research suggests that girls with ADHD are more likely to present with difficulties such as sustaining attention and distractibility, while more outwardly hyperactive or impulsive symptoms may be less prominent. That can make ADHD easier to miss and easier to misinterpret. A 2025 systematic review of ADHD presentation in females explores this distinction.
The Child Mind Institute also notes that girls may work hard to mask their difficulties, with consequences for self-esteem. So when a 13-year-old forgets her period products again, the more useful question may not be, “Why didn't you think ahead?” but “What could make thinking ahead easier next time?” That's a very different conversation.
(Hormones have entered the chat.)
We know that hormone levels change substantially across the menstrual cycle. We also know that estrogen and progesterone interact with brain systems involved in mood, cognition, motivation, and attention.
What we're still learning is exactly how those changes interact with ADHD. The research is not yet strong enough to say that every person with ADHD will experience a predictable monthly pattern. But there is enough emerging evidence to take the possibility seriously.
The thing nobody told you: If your ADHD feels harder to manage at certain points in your cycle, you're not making that up. Your body may be affecting how your symptoms show up.
A 2025 systematic review of ADHD and sex hormones in females identified 11 studies examining ADHD symptoms in relation to hormonal changes, including puberty and the menstrual cycle. The authors found evidence that was largely suggestive of a relationship, but emphasized that the research is limited by small samples, relatively few studies, and considerable variation in how symptoms and hormone-related changes were measured. A 2026 study of more than 600 females also found higher rates of menstrual irregularity and more severe premenstrual symptoms among participants with ADHD, although the authors emphasize that more research is needed to understand why these differences occur.
A 2026 scoping review of menstrual health and ADHD identified 20 studies involving people ages 13–49. The review found recurring evidence of ADHD symptoms worsening during particular phases of the menstrual cycle, as well as links between ADHD symptoms and menstrual pain, irregular or heavy periods, and some medication-related menstrual effects. The authors also emphasized that much more rigorous and inclusive research is needed.
We're not at the point where we can say, “Your period causes your ADHD symptoms to get worse.” But we can say, “There is growing evidence that hormonal changes across the menstrual cycle may affect how ADHD symptoms are experienced.” For someone who has been thinking that everything suddenly feels harder at certain points in their cycle, that can be extremely validating.
What if her medication suddenly seems to stop working? This is a question parents may recognize immediately. Maybe her medication seems to work beautifully most of the month. Then, for several days, it feels as though someone quietly swapped it out for a Tic Tac. She can't concentrate. Everything feels harder. Homework takes forever. She is more irritable. She is overwhelmed by things that normally don't bother her. Is the medication not working? Maybe. Is something else happening? Possibly.
The thing nobody told you: Your medication isn't necessarily “not working” just because some days feel different. Notice the pattern before you blame yourself or your medication.
Research into ADHD medication and the menstrual cycle is still quite limited. A 2025 review of psychostimulants in menstruating women with ADHD found only a small number of relevant studies and concluded that the relationship between menstrual-cycle phase, ADHD symptoms, and stimulant effectiveness remains poorly understood.
There is also a very small case study involving nine women with ADHD who experienced premenstrual worsening of ADHD and mood symptoms. Their clinicians adjusted stimulant dosage during the premenstrual period, and all nine reported improvement. That's interesting, but nine people is nowhere near enough evidence to turn into a universal treatment recommendation.
So the takeaway for parents isn't, “Increase her medication before her period.” Please don't do that without her prescriber. The takeaway is to notice the pattern. Write it down. Bring the pattern to her clinician.
A particularly interesting 2026 pilot study followed 30 females taking amphetamine salts for ADHD and asked them to report symptoms, mood, and medication use daily across a menstrual cycle. ADHD symptoms were significantly associated with menstrual-cycle phase, with symptoms highest during menstruation and comparatively milder during the mid-follicular phase. Changes in ADHD symptoms were also associated with changes in negative mood. It's a small pilot study, so it gives us something to investigate, but again, it’s not a prescription. But that distinction is important because tracking can turn “Something is wrong” into “I notice a pattern.” And a pattern is useful information.
When our ADHD has feelings about our feelings.
ADHD isn't only about attention. For many people with ADHD, emotional regulation can also be difficult. Strong feelings may arrive quickly, feel particularly intense, or take longer to settle. Research in young adolescents with ADHD has identified difficulties including emotional excitability and impatience, difficulty regulating behavior when emotions are strong, and difficulty returning to emotional baseline.
Now add the hormonal and physical changes that can accompany the menstrual cycle. Cramps. Fatigue. Changes in sleep. Changes in appetite. Headaches. Bloating. PMS. And, for some girls, a sudden sense that everyone in the history of humanity has decided to make it their life’s mission to be annoying.
It is not difficult to imagine why a girl who already has a hard time regulating emotions might feel even less regulated during certain parts of her cycle.
The thing nobody told you: Sometimes the problem isn't that everyone suddenly becomes annoying. Sometimes your emotional bandwidth just got very, very small.
That doesn't mean we should dismiss her feelings as hormonal. Quite the opposite. It means we can take the feelings seriously while also helping her understand that her capacity may change from day to day. AND, that changing capacity is not the same thing as changing character.
The emerging research supports thinking about hormonal fluctuations as one possible contributor to changes in ADHD symptoms, mood, sleep, and perceived treatment effectiveness, rather than as a single explanation for everything that happens across a menstrual cycle. A 2025 clinical review on hormonal fluctuations and female ADHD makes this distinction particularly well.
Before we ask, “Why Can't You Just…?”
This might be one of the most important conversations we can have with girls with ADHD. Because personal hygiene is full of executive-function tasks. Shower. Wash hair. Use deodorant. Put on clean clothes. Do laundry. Change menstrual products. Remember to change them again. Clean up after an accident. Notice that the towel you have been using for…an unspecified amount of time…may perhaps be ready for the washing machine. Not the floor.
The thing nobody told you: If something is hard to remember, put it somewhere you can see it.
But there's another piece worth considering here: not every “hygiene” expectation is actually a health requirement. Some are shaped by culture, family, gender expectations, advertising, social norms, and ideas about what a girl or young woman is supposed to look and smell like. How often someone should shave, wash their hair, remove body hair, use particular products, wear makeup, or otherwise groom themselves can have a lot more to do with social expectations than with health. A conversation about hygiene is worth having without assuming there is one universal standard every girl should be trying to meet.
That doesn't mean those expectations don't matter to the girl. If she wants to shave her legs because she likes having smooth legs, that matters. If she wants to smell like vanilla cupcakes because vanilla cupcakes are delightful, also fair. The point is to give her some room to ask, What actually helps me feel healthy and comfortable? What do I want for myself? And what am I doing because I think I'm supposed to?
The thing nobody told you: Not every “hygiene” rule is a health rule. Some are just things we've been taught girls are supposed to do.
And then there is the ADHD piece.
Many hygiene tasks are repetitive, private, mildly unpleasant, and have very little immediate reward. For an ADHD brain, that matters a lot. So, if a teenager consistently struggles with hygiene, the answer doesn't have to be a louder reminder. And it definitely shouldn’t be shame. “You need to take better care of yourself” may be true as an observation, but it isn't much of a strategy.
Instead: What part of the task is getting stuck? Is she forgetting? Is she overwhelmed by the number of steps? Does she lose track of time? Does she hate the sensory experience of showering? Does she get distracted halfway through? Does she remember only when she is already late? Does she genuinely not notice that she needs to change her menstrual product? Does the task feel so boring that her brain simply refuses to engage?
The thing nobody told you: If “just remember to do it” worked for ADHD brains, we could probably wrap up this entire article in one sentence.
Once we know where the process breaks down, we can actually do something about it. Because shame is not an executive-function strategy.
The thing nobody told you: Sometimes the problem isn't remembering to do the thing. Sometimes the thing itself isn't accessible.
Problems with accessibility can exacerbate a struggle that we’ve outlined to already be exacerbated 3 x’s over. And not every girl has the same amount of flexibility. Some are navigating chronic illness or disability. Some don't have reliable access to menstrual products, private bathrooms, transportation, or supportive adults. Some are balancing school with caregiving, work, athletics, or other responsibilities. “Just plan ahead” assumes you have the time, resources, privacy, and support to plan ahead.
The thing nobody told you: A strategy can be reasonable and still be impossible when the resources aren't there.
Design the system around the person.
One of the most useful things we can do for someone with ADHD is to stop requiring their brain to be the only place where the system lives. If remembering is difficult, build reminders into the environment. Keep period supplies in more than one place. At home. In a backpack. In a locker. In a sports bag. In a purse. In the other purse. Maybe in the overnight bag. If there is somewhere she regularly spends time, consider whether having supplies there would make life easier.
The Child Mind Institute's practical recommendations include keeping menstrual products in multiple locations and using phone reminders to help with changing products. They also suggest planning for nighttime protection and preparing ahead for the days when PMS symptoms tend to be more difficult.
The thing nobody told you: You don't have to remember everything if you can build a system that remembers for you.
The principle is simple: make the desired behavior easier to remember than to forget. And then let her help design the system. Maybe she hates an app. Maybe she loves one. Maybe a discreet vibrating reminder works. Maybe a sticky note on the bathroom mirror works. Maybe a basket next to the toothbrush is better. Maybe she’ll be more cognizant when the packaging has a certain look or appeal. Maybe flushable wipes for quick and easy cleanup would help. Maybe the answer is simply: “Every bathroom gets a period kit.”
The thing nobody told you: There is no prize for doing this the hardest possible way.
Track the pattern, not the girl.
One of the most useful things a teenager can learn is, “Huh. I notice this tends to happen around this time.”
That might be, “My ADHD symptoms feel harder to manage right before my period.” Or, “I get really tired during the first few days.” Or, “I always forget to pack supplies when I’m rushing in the morning.” Or even, “Apparently I become deeply offended by everyone who speaks to me two days before my period.”
The thing nobody told you: Having a harder day doesn't mean you're failing.
She doesn't need a spreadsheet. She doesn't need to track every symptom every day. And she definitely doesn't need Mom becoming the CEO of Menstrual Operations. You’ve no doubt already given yourself a few other C-level responsibilities.The goal is for a girl to begin noticing: My period tends to come around this time. I have more trouble sleeping right before it. I get more irritable. My medication seems less helpful. Homework takes me twice as long. I am much more likely to forget things. I want to be alone. I have absolutely no interest in doing anything you tell me to even if I was already going to do it. Okay, maybe that last one is not cycle-specific. But you get the idea.
A simple tracking system can help turn “I feel like this happens sometimes” into “I've noticed this pattern a few times.”
Period-tracking apps such as Clue and Flo can track cycle dates and symptoms, while an app like Bearable can be used to look at relationships between menstrual-cycle phases and things like mood, sleep, energy, and other symptoms.
For a teenager with ADHD, the most useful tracking may be very simple: period + mood + energy + sleep + ADHD symptoms. That's enough to start noticing patterns without turning her life into a research study.
The thing nobody told you: Helpful for someone else doesn't automatically mean helpful for you. It’s ok to try all the things to see what fits you best.
The goal isn't to predict exactly how she's going to feel on Day 23. Her body isn't a calendar, and it doesn't have to be perfectly predictable. The goal is simply to gather enough information that she can begin to say, “Oh. This is something that happens to me sometimes. Maybe I can plan for it.”
That's a very different message from “Here we go again. You're being difficult.”
The thing nobody told you: You aren't tracking what's wrong with you. You're learning what helps.
Plan for the version of her who has less bandwidth.
This may be my favorite strategy of all.
If you know there are a few days each month when everything feels harder, don't build a plan that assumes those will be your most productive days. Build a plan that assumes capacity fluctuates.
That might mean:
starting a big project earlier
breaking assignments into smaller pieces
scheduling fewer unnecessary commitments
protecting sleep
making meals easier
keeping period supplies accessible
planning extra time in the morning
using reminders
building in movement if it helps
giving herself permission to need more downtime
talking with teachers when appropriate
identifying what can be postponed and what truly cannot
The thing nobody told you: Your body isn't doing something wrong because it isn't predictable every single day.
We do this all the time for other things. If you know you're going to be traveling on Thursday, you don't schedule your biggest project to begin Thursday morning. If you know your daughter has a championship game Saturday, you don't assume Saturday morning is the perfect time to start a ten-page research paper. And if she knows that certain days of her cycle tend to be harder, it makes sense to plan accordingly.
The thing nobody told you: Accommodations aren’t lowering expectations. They’re planning intelligently around the information you have.
Let her be part of the conversation.
There is a temptation, especially when a child is struggling, for adults to take over. We remind. We organize. We buy. We track. We text. We make appointments. We quietly put supplies in the backpack. And then one day she is 19 and standing in a pharmacy aisle thinking, “Wait. What am I supposed to be buying?”
The long-term goal isn't for parents to become exceptionally good at managing their daughter's ADHD. The goal is for the girl to become increasingly good at understanding her own brain.
The thing nobody told you: You get to figure out what makes you feel clean, comfortable, and like yourself.
So ask her. What is hardest part of your cycle? Of your period? What do you forget? What feels embarrassing? What would make this easier? What kind of reminder would you actually use? Do you notice a difference at different times of the month? What do you wish people understood? What do you wish I understood?
And sometimes the answer may surprise you. She may not need another reminder. She may need a different system. She may not need more consequences. She may need fewer steps. She may not need someone to tell her to care. She may need help figuring out how to turn caring into action.
And maybe that's the bigger lesson.
The thing nobody told you: Learning to manage a period is not really about learning to manage a period. It's about learning how to listen to your body. How to notice patterns. How to prepare. How to ask for help. How to build systems around a brain that may not always cooperate with the systems everyone else seems to manage effortlessly. And, perhaps most importantly, how to stop interpreting every difficult thing as evidence that something is wrong with you. (More to take in here, I know. But it’s important. Maybe give this short paragraph another quick read.)
For a girl with ADHD, there will probably be plenty of moments when her brain and her expectations collide. She will forget things. She will lose things. She will underestimate how long things will take. She will have days when she can hyperfocus on something for four hours and days when putting away a clean towel feels like an unreasonable request from the universe. She will have hormones doing their own thing in the background. She may have days when her medication feels different. She may be more emotional than usual. She may need more sleep. She may need more help.
None of those things make her lazy, careless, immature, dramatic, or broken. They are information. And information gives us somewhere to start.
The thing nobody told you: You don't have to be good at managing your period. You can be good at knowing what helps you manage it.
The goal isn't to create a girl who never forgets a pad, never loses her temper, never misses a shower, and somehow emerges from adolescence with a color-coded menstrual calendar and perfect executive functioning. (Although, for a few days, that may sound to her like the perfect solution which might require a trip to the store for new markers, colored tabs and a wall calendar.
The goal is something much more useful: a girl who knows herself well enough to notice when something is hard—and knows what she can do to make it a little easier. Sometimes that means a reminder. Sometimes it means a backup plan. Sometimes it means asking for help. And sometimes it means saying, “Oh. This is one of those days.”
What looks like “not trying” from the outside may be something entirely different from the inside. The same expectation can land very differently depending on the person, their brain, their body, their history, their environment, and the resources available to them. So before we decide someone isn't trying, get curious about what is actually getting in the way.
Instead of deciding that she has failed again, figuring out what she needs next.
The thing nobody told you: You are not bad at taking care of yourself. You may just need a different way of getting things done.
