Inpatient vs. Outpatient Mental Health Treatment

Maybe a genetic report flagged it. Maybe a friend, a forum, or a supplement ad told you it could explain your fatigue, your depression, or why medication never quite worked. Now you're wondering what an MTHFR gene mutation actually means for you.

MTHFR variants are extremely common. Most people who carry them have no health effects at all, and research linking them to mental health conditions shows a real but small association, not a cause. Medical experts don't recommend routine testing for them.

What the MTHFR gene does

The MTHFR gene carries instructions for an enzyme called methylenetetrahydrofolate reductase. That enzyme converts folate, a B vitamin, into the active form your body uses to turn the amino acid homocysteine into methionine. According to MedlinePlus Genetics, the active form, 5-methyltetrahydrofolate, is the main form of folate found in blood.

When the enzyme works less efficiently, homocysteine can build up. That's the mechanism behind most of the interest in MTHFR, including the mental health questions.

C677T, A1298C, heterozygous, and homozygous

Most people searching "MTHFR gene mutation" are really asking about two common variants:

• C677T. The most common and best studied. At position 677 in the gene, the DNA base C is replaced by T. The resulting enzyme is less stable and less active, especially in people with two copies.
• A1298C. The second common variant. The CDC notes there isn't enough evidence that A1298C on its own significantly affects how the body processes folate.

You inherit one copy of the gene from each parent, which is where the lab terms come from:

• Heterozygous means one copy carries the variant (for C677T, written CT).
• Homozygous means both copies carry it (TT).
• Compound heterozygous means one copy of C677T and one copy of A1298C.

These variants are so common they're closer to normal human variation than to a disease. The CDC reports that more people in the U.S. have one or two copies of C677T than don't. Having both copies is less common: MedlinePlus estimates about 25% of Hispanic people and 10% to 15% of North American white people carry two copies of C677T.

MTHFR symptoms: what the variant does and doesn't cause

Most people with common MTHFR variants have no symptoms. Cleveland Clinic puts it plainly: MTHFR gene variants most often don't affect your health or cause symptoms. When they do matter, it's usually through higher homocysteine or lower folate, and mostly in people with two copies of C677T. Even then, how much folate you get from food matters more than your genotype.

That's different from what you'll read on many wellness sites, which attribute everything from fatigue to brain fog to MTHFR. There's no reliable evidence for a list of "MTHFR symptoms" in people with the common variants. If you have symptoms, they deserve an evaluation, not an assumption that a gene variant explains them.

There is one important exception. Rare, severe mutations in the MTHFR gene cause homocystinuria, a serious inherited condition whose symptoms usually appear early in life. Most U.S. newborns are screened for it shortly after birth. That's a different situation from the common C677T and A1298C variants.

MTHFR and mental health: what research shows

Because MTHFR sits in the folate and methylation pathway, researchers have looked hard for links to psychiatric conditions. The findings are consistent in one way: the effect is modest.

• Depression. A 2013 meta-analysis of 26 studies, with 4,992 people with depression and 17,082 controls, found that two copies of C677T were associated with higher odds of depression (odds ratio 1.42). The link was stronger in Asian populations, marginal in white populations, and absent in older adults.
• Schizophrenia, bipolar disorder, and depression combined. A 2011 meta-analysis of case-control studies with 29,502 participants found TT carriers had modestly higher odds of these conditions as a group (odds ratio 1.26). The authors read this as evidence of a shared genetic vulnerability across the three conditions.

An odds ratio of 1.26 to 1.42 is a small increase in relative risk for a very common genotype. Most people with two copies of C677T never develop depression, bipolar disorder, or schizophrenia, and most people with those conditions don't have two copies. Mental health conditions come from many genes and life experiences acting together. MTHFR is, at most, one small piece.

Folate, folic acid, and methylfolate

A common online claim is that people with MTHFR variants can't use folic acid and need "methylated" supplements instead. The CDC says that isn't true: people with an MTHFR variant can process all types of folate, including folic acid. People with the TT genotype have blood folate levels only about 16% lower on average than people with CC at the same intake, and folic acid intake matters more than genotype in determining blood folate.

L-methylfolate, the active form, has been studied as an add-on to antidepressants. In two randomized trials published in the American Journal of Psychiatry in 2012, adults with depression that hadn't responded fully to an SSRI received L-methylfolate or placebo alongside their medication. The first trial, with 148 patients starting at 7.5 mg a day, found no difference. The second, with 75 patients at 15 mg a day, found a significant benefit over placebo. Both enrolled people based on their depression, not on a genetic test. Whether any add-on makes sense for a specific person is a clinical decision that depends on their full history.

For more on how folate and other nutrients relate to mood, see our article on nutrient deficiencies and anxiety.

Should you get tested for MTHFR?

For most people, no. MedlinePlus states that medical experts don't recommend testing for common MTHFR gene changes in most cases. A provider may order it in specific situations, such as high homocysteine on a blood test combined with a family history.

The American College of Medical Genetics and Genomics went further in a 2013 practice guideline: MTHFR polymorphism testing has minimal clinical utility and shouldn't be part of a routine evaluation for blood clotting disorders. Recent meta-analyses had disproven the links that originally motivated the testing.

If you already have a result, it's still useful context to share with your care team. It just isn't a diagnosis, and it isn't a treatment plan.

When depression or mood symptoms don't improve

People often look up MTHFR because something isn't working: depression that keeps coming back, medication that only half helps, or mood swings no one has explained. Those problems are real, even if MTHFR is unlikely to be the answer. They usually call for a fuller psychiatric evaluation: a closer look at the diagnosis, past medication trials, co-occurring conditions, sleep, substance use, and physical health.

That's the kind of care we provide at Amae Health. Our clinics specialize in conditions including Major Depressive Disorder, bipolar disorder, and schizophrenia. Our care teams bring psychiatrists, therapists, primary care physicians, and dietitians under one roof, so lab results, nutrition, and medication history are reviewed together, by people who share one treatment plan.

Frequently asked questions

How common is the MTHFR gene mutation?

Very common. According to the CDC, more people in the U.S. have one or two copies of the C677T variant than don't. Two copies are less common, estimated at about 25% of Hispanic people and 10% to 15% of North American white people.

What are the symptoms of being MTHFR C677T heterozygous?

Usually none. According to MedlinePlus, raised homocysteine is seen mainly in people with two copies of C677T. If you have symptoms, they need an evaluation of their own rather than being attributed to one copy of a common variant.

Does MTHFR cause depression?

No single gene causes depression. Two copies of C677T are associated with modestly higher odds of depression in meta-analyses, with an odds ratio around 1.4, but most people who carry them never develop depression.

Do people with MTHFR need methylfolate instead of folic acid?

According to the CDC, no. People with MTHFR variants can process folic acid, and folic acid intake matters more than genotype for blood folate levels. L-methylfolate has been studied as an add-on treatment for depression, regardless of MTHFR status, and decisions about it belong with a clinician.

Is MTHFR testing worth it?

For most people, it isn't recommended. Medical genetics experts say the common variants have minimal clinical utility. A provider may order testing in specific cases, such as unexplained high homocysteine with a family history.

Key takeaways

• An MTHFR gene mutation usually means one or two copies of the common C677T or A1298C variants, which most people carry without health effects.
• Two copies of C677T can raise homocysteine and are linked to modestly higher odds of depression, bipolar disorder, and schizophrenia, but the effect is small.
• People with MTHFR variants can process folic acid, and routine MTHFR testing isn't recommended.
• If depression or mood symptoms aren't improving, a full psychiatric evaluation is more useful than a gene result.

If you or someone you love is living with depression, bipolar disorder, or schizophrenia that hasn't responded to treatment, request an intake appointment. Our team will walk you through how an evaluation works and what to bring, including any lab or genetic results you already have.

Petulant BPD is an informal name for one of four subtypes of Borderline Personality Disorder described by psychologist Theodore Millon. It isn't a separate diagnosis: petulant borderline personality disorder doesn't appear in the DSM-5-TR, and a clinician would diagnose Borderline Personality Disorder (BPD). People described this way tend to show their distress on the outside, through irritability, resentment, stubbornness, and relationships that swing between clinging and pushing away. And because it's BPD, it's treatable.

Is Petulant BPD a Real Diagnosis?

Not as its own diagnosis. The diagnosis is BPD, which a licensed mental health professional makes after a full evaluation, usually an interview about symptoms, history, and family background.

Subtypes are descriptive. Millon described four BPD subtypes: discouraged, impulsive, petulant, and self-destructive. Each one is a way of grouping the patterns a person with BPD tends to show most. They help a partner or parent see why a loved one's BPD may look nothing like the textbook description.

There are no reliable figures on how many people with BPD fit the petulant pattern. Many people show traits from more than one subtype.

Petulant BPD Symptoms and Signs

Petulant BPD symptoms are the core features of BPD, expressed outwardly. Underneath most of them sits an intense fear of being rejected or left. That doesn't make the behavior easy to live with. It makes it easier to understand.

Irritability and anger that flares quickly

Small things can set off big reactions: a late reply, a change of plans, a tone of voice. The anger often comes fast and fades fast, sometimes followed by guilt or shame. If outbursts are a regular problem, our guide to managing emotional outbursts covers practical steps.

Resentment and feeling unappreciated

Resentment often comes up in descriptions of the petulant pattern: a person may feel chronically overlooked, as if others never give back what they put in. Old grievances resurface in new arguments.

Passive-aggressive behavior and stubbornness

For some people, instead of saying "I'm hurt," the hurt leaks out sideways: sulking, silent treatment, agreeing and then not following through, or digging in on a small point. Stubbornness may work as self-protection, a way to avoid feeling controlled.

Swinging between neediness and pushing people away

This is the push-pull pattern. One day the person wants constant closeness and reassurance. The next, they pick a fight or withdraw, sometimes to test whether the other person stays.

Intense fear of abandonment

Real or imagined signs of rejection can feel unbearable. A partner's night out with friends can register as proof they're leaving.

All-or-nothing thinking (splitting)

People and situations get sorted into all good or all bad, with little room in between. A friend can go from "the only one who understands me" to "just like everyone else" after a single disappointment.

Chronic emptiness

Many people with BPD describe a persistent hollow feeling, a sense of not knowing who they are or what they want.

Mood shifts in BPD often last from a few hours to a few days and tend to follow events, which is one way they differ from the longer mood episodes described in our article on BPD vs. bipolar. Substance use and eating disorders can also occur alongside BPD, and these co-occurring disorders shape how treatment is planned.

BPD and Controlling Behavior

BPD controlling behavior is one of the hardest parts of the petulant pattern for partners and families. It can look like:

• Checking a partner's phone or location, or demanding constant updates
• Getting upset about time spent with friends or family
• Using guilt ("after everything I've done for you")
• Threatening to leave, or threatening to end the relationship first
• Insisting on control over plans, money, or small daily decisions

Most of the time, this behavior is an attempt to prevent a feared abandonment. If you can predict where someone is and who they're with, the fear quiets for a while. Then it comes back, and the checking starts again. The relief never lasts, which is why the behavior tends to escalate rather than settle.

Understanding the cause is not the same as accepting the behavior. A partner doesn't have to tolerate being monitored, threatened, or cut off from friends. Clear boundaries ("I'll answer when I'm done with work, not every 10 minutes") protect both people, and they work best when they're calm, specific, and consistent. If controlling behavior includes threats of self-harm, take them seriously: see the crisis answer in the FAQ below.

Labels that end the conversation don't help. The fear underneath is what treatment works on.

How Petulant BPD Affects Relationships, Work, and Daily Life

In romantic relationships, the push-pull pattern is exhausting for both people. Closeness feels risky, distance feels like rejection, and arguments can start over very little. For example, a friend cancels plans because they're sick. A person with petulant BPD traits may hear "I don't want to see you," react with anger or a cold message, and then feel ashamed and afraid they've ruined the friendship.

Family members often describe walking on eggshells.

At work, feedback can land as a personal attack. A routine note from a manager may trigger defensiveness, resentment that lingers for days, or a sense of being singled out.

None of this means the person doesn't care. Often they care intensely, which is part of why every slight hurts so much.

Petulant BPD vs. Other Types of BPD

Millon's four types of BPD differ mainly in where the distress goes: inward, outward, or into action.

SubtypeHow distress showsTypical patternDiscouragedInwardDependent and avoidant, clings to a few people, turns anger on themselvesImpulsiveInto actionRisk-taking, thrill-seeking, acting before thinkingPetulantOutwardIrritability, resentment, stubbornness, push-pull relationshipsSelf-destructiveAgainst the selfSelf-sabotage and self-harm, bitterness turned inward

The impulsive, petulant, and self-destructive rows are general summaries of Millon's model, not findings from a single study.

The discouraged type is the one described as dependent and avoidant, with distress turned inward. It's the closest match to what people call quiet BPD. Petulant BPD is close to its opposite: the same fear of abandonment, expressed loudly.

What Causes Petulant BPD?

We found no research on causes specific to the petulant subtype. Research covers BPD as a whole, and it points to several factors working together.

Genetics and family history

BPD tends to run in families. Having a close relative with BPD raises the risk, and genes are thought to be one factor among several.

Brain differences in emotion regulation

Studies of people with BPD have found differences in brain areas that handle emotion and impulse control. These findings describe groups, not individuals, and it isn't clear whether these differences are a cause or a result of BPD.

Childhood trauma, neglect, or invalidation

Abuse, neglect, early loss, or growing up in a home where feelings were dismissed are common in the histories of people with BPD. Not everyone with BPD has this history.

Having risk factors doesn't mean someone will develop BPD. Plenty of people have several and never do.

How Petulant BPD Is Treated

Treatment for petulant BPD is treatment for BPD, tailored to the person. Psychotherapy comes first.

Dialectical behavior therapy (DBT)

DBT was developed specifically for people with BPD. It uses mindfulness and teaches skills to manage intense emotions, reduce self-destructive behavior, and improve relationships. For the petulant pattern, that can mean learning to ask for what you need without an explosion.

A 2017 meta-analysis in JAMA Psychiatry by Cristea et al. found DBT and psychodynamic approaches were the only therapy types more effective than control conditions, though effects were small and likely inflated by study bias. Therapy helps. Real change takes steady work over time.

Other therapies: mentalization-based therapy and CBT

• Mentalization-based therapy (MBT) builds the ability to understand your own mental states and other people's, which helps when a neutral comment gets read as an attack.
• Cognitive behavioral therapy (CBT) works on the link between thoughts, feelings, and actions, such as catching an all-or-nothing thought before it turns into an argument.

The role of medication

According to NIMH, the benefits of medication for BPD itself are unclear, and medication isn't usually the first treatment. A psychiatrist may prescribe it for specific symptoms or for co-occurring conditions such as depression, and weighs the benefits against side effects with the person.

Can Petulant BPD Get Better?

Yes. BPD is treatable, and many people find that symptoms ease with treatment over time. Progress usually isn't a straight line: good months, a setback, then a steadier stretch.

Alongside therapy, a few habits help:

• Noticing triggers. Write down what happened right before an outburst. Patterns show up within a few weeks.
• Practicing DBT skills between sessions, not only in them.
• Keeping a mood journal, so you and your care team can see changes you might miss day to day.
• Protecting sleep and moving your body. Poor sleep makes irritability worse for almost everyone.

These are supports, not substitutes for treatment.

How to Support Someone With Petulant BPD

If you love someone with petulant BPD traits, feeling tired, confused, and sometimes guilty is normal.

• Validate the feeling, not the behavior. "I can see you're really hurt" doesn't mean "you're right to yell at me."
• Set clear, consistent boundaries. Say what you will and won't do, then follow through every time.
• Don't escalate. Step away from an argument that's spiraling and come back when you're both calmer.
• Encourage professional care without making it an ultimatum in the heat of a fight.
• Look after your own mental health. Your own therapist or a family support group is not a betrayal.

Our guide on how to help someone with mental health issues goes further into those conversations.

When to Seek Help and How We Treat BPD at Amae Health

Weekly therapy is enough for some people. Others need more structured care, especially when there is:

• Self-harm or suicidal thoughts
• BPD alongside depression, bipolar disorder, or substance use
• Repeated crises, ER visits, or hospital stays
• Relationships, work, or school falling apart despite outpatient therapy

Borderline Personality Disorder and co-occurring substance use disorder are among the conditions we specialize in at Amae Health. Our care is in person and led by psychiatrists, for adults 18 and older. Each patient has a multidisciplinary team under one roof: psychiatrists, therapists, primary care physicians, dietitians, health coaches, peer mentors, and clinical care coordinators. Depending on the level of support needed, care can include a Partial Hospitalization Program (PHP) or an Intensive Outpatient Program (IOP), alongside individual and group therapy. You can read more about our care model.

If petulant BPD traits are shaping your life or a loved one's, you can request an intake appointment and our team will talk through what kind of care fits.

Frequently Asked Questions

Is petulant BPD a real diagnosis?

No. The diagnosis is Borderline Personality Disorder; "petulant" is one of four descriptive subtypes from Theodore Millon's work, not a DSM-5-TR category. The label can still help people and families recognize a pattern of outward irritability, resentment, and push-pull relationships, and find information that fits what they're living with.

What is the difference between petulant BPD and quiet BPD?

Both share the fear of abandonment at the core of BPD. Petulant BPD turns distress outward, through irritability, resentment, and conflict. Quiet BPD, closest to Millon's discouraged type, turns it inward, so others may not notice.

How is petulant BPD treated?

The same way as BPD: psychotherapy first, including DBT, which was developed specifically for BPD, and options such as mentalization-based therapy. Medication may be used for specific symptoms or co-occurring conditions such as depression, decided with a psychiatrist.

Can petulant BPD get better?

Yes. BPD is treatable, and symptoms often ease with treatment over time. Recovery takes patience and usually isn't linear: setbacks happen, and they don't erase progress.

Is petulant BPD the same as narcissism?

No. Borderline Personality Disorder and Narcissistic Personality Disorder are separate diagnoses in the DSM-5-TR, even though both can involve anger and relationship conflict. A thorough evaluation by a mental health professional is the way to tell them apart, and some people meet criteria for both.

Why does someone with BPD try to control me?

Controlling behavior usually comes from fear of being left. That explains it, but it doesn't excuse harm. Calm, consistent boundaries and encouraging treatment help more than arguing about each incident.

What should I do if someone with BPD talks about suicide?

Take it seriously every time. Stay with them if it's safe, and call or text 988, the 988 Suicide & Crisis Lifeline. If there's immediate danger, call 911.

ADHD in women vs. men is the same condition. What differs is how visible the symptoms are, especially in childhood, and how quickly people get diagnosed. Boys are around three times more likely to be diagnosed with ADHD in childhood, according to the Duke Center for Girls and Women with ADHD. By adulthood, the same source notes, rates are equal. So the gap is less about who has ADHD and more about who gets noticed, and when.

ADHD in Women vs. Men at a Glance

These are tendencies, not rules. Plenty of girls are hyperactive, and plenty of men mostly struggle with focus. The sections below explain where each row comes from.

The Three ADHD Presentations Apply to Everyone

The National Institute of Mental Health describes ADHD as a neurodevelopmental disorder marked by inattention, hyperactivity, and impulsivity that are frequent, show up across settings, and interfere with daily life. The CDC uses the term "presentations" and names three:

• Predominantly Inattentive Presentation: trouble organizing, finishing tasks, following details, or keeping track of things.
• Predominantly Hyperactive-Impulsive Presentation: fidgeting, talking a lot, trouble waiting, acting before thinking.
• Combined Presentation: symptoms of both are present.

Any of the three can occur in anyone, of any sex. Because symptoms can change over time, the CDC notes, a person's presentation can change too. ADHD symptoms can continue into adulthood but may look different in adults. If attention problems overlap with reading or math difficulties, our guide to learning disabilities vs. ADHD explains how the two differ.

ADHD Symptoms in Women vs. Men

When people compare ADHD symptoms in women vs. men, they're usually comparing tendencies within the same three presentations. Here's how those tendencies often look.

How ADHD Often Shows Up in Boys and Men

In boys, ADHD more often shows up in outward behavior that other people can see. In a 2025 study of adults with ADHD, men were more likely than women to recall leaving their seat as children (45.97% vs 34.96%). Common examples:

• Leaving a seat in class, fidgeting, or seeming always "on the go"
• Blurting out answers and interrupting
• Making quick, impulsive decisions

Because these behaviors disrupt a classroom or a household, adults tend to notice them early.

How ADHD Often Shows Up in Girls and Women

In girls and women, ADHD more often turns inward. Inattention is common: losing the thread of a conversation, misplacing things, drifting off during long tasks.

Some women describe compensating: making lists, redoing work late at night, putting in extra effort. That effort can make symptoms harder for others to see. It also wears people down.

For the full picture of how this looks in daily life, including masking, see our guide to high-functioning ADHD in women.

ADHD in Girls vs. Boys: Why the Diagnosis Gap Starts in Childhood

The difference between ADHD in girls vs. boys starts with who gets referred. Disruptive behavior gets attention fast. A child who is quietly lost in thought doesn't.

The bias has deep roots. In 1902, the pediatrician George Still published some of the earliest clinical descriptions of what we now call ADHD. Of his 20 cases, 15 were boys. For much of the following century, the textbook picture of the condition looked like those boys.

Girls' symptoms still don't fit that picture well. The Duke Center notes that ADHD in girls and women is often missed completely or misinterpreted as other conditions, and that co-occurring anxiety and mood disorders can make it harder to identify. A girl who can't focus may be told she's anxious. A girl who is anxious because she can't keep up may only get treated for the anxiety.

None of this means girls have milder ADHD. It means their ADHD is easier to overlook.

Do Women and Men With ADHD Look More Alike in Adulthood?

Largely, yes. This is the part of the comparison most articles skip.

The Duke Center reports that adult rates of ADHD are equal in men and women, and that women are more likely than men to be first diagnosed as adults. Many of those women went through childhood without anyone naming what was going on.

A 2025 study in Frontiers in Global Women's Health looked at 2,257 adults diagnosed with ADHD at clinics in the Netherlands. The researchers concluded that ADHD shows up in a remarkably similar way in men and women. Where differences existed, they were small. In several adult symptoms, women reported higher rates: 80.38% of women said they lose things, compared with 71.40% of men. Looking back on childhood, men more often recalled classroom hyperactivity, with 45.97% reporting leaving their seat, compared with 34.96% of women.

The study has limits. It included only people who had already been diagnosed, it came from one country, and the authors call it exploratory. Still, it fits the larger pattern. The sharpest differences between ADHD in males vs. females appear in childhood, when outward behavior drives who gets seen. By adulthood, the symptoms themselves look much the same.

Hormones and ADHD Symptoms Across the Lifespan

Hormones come up often in this comparison. The science is early. The Duke Center describes emerging research into how hormone changes, such as those across the menstrual cycle and in menopause, may affect ADHD symptoms and treatment. It also states plainly that more research is needed.

Some women do notice that their focus or mood shifts at certain points in their cycle or around menopause. Keeping track of those patterns gives a clinician who knows your history something concrete to work with. But the research doesn't yet support firm conclusions about why it happens or what to change. Any decision about medication belongs in that clinical conversation, not in an article.

When ADHD Comes With Depression, Anxiety, or Bipolar Disorder

ADHD rarely travels alone. The Duke Center notes that girls and women with ADHD often also have anxiety and mood disorders.

That overlap makes diagnosis harder for everyone. Poor concentration, restlessness, sleep problems, and mood changes can come from ADHD, depression, anxiety, or bipolar disorder. They can also come from more than one at once. Sorting out which is which takes a careful psychiatric evaluation that looks at your full history, not a quick checklist.

This is where we can help. ADHD on its own isn't an Amae specialty. But our psychiatry-led teams work with adults whose ADHD occurs alongside depression, anxiety, or bipolar disorder, where the mood or anxiety symptoms are a large part of what's making life hard. You can read about bipolar disorder treatment at Amae or learn more about our care model.

Conclusion

ADHD in women vs. men is one condition with two common patterns of visibility. Boys are more often noticed early because their symptoms are louder, while girls are more often missed and diagnosed later, sometimes as adults. In adulthood, the symptoms look much more alike. If ADHD is showing up alongside depression, anxiety, or bipolar disorder, you can contact us to talk with our team about whether our care fits what you need.

Frequently Asked Questions

Is ADHD more common in men or women?

It depends on whether you mean diagnosis or occurrence. Boys are around three times more likely than girls to be diagnosed in childhood. In adulthood, rates are equal, according to the Duke Center for Girls and Women with ADHD. Much of the childhood gap reflects who gets noticed, not who has ADHD.

Why is ADHD underdiagnosed in girls?

Girls' symptoms are often less disruptive, so they're less likely to prompt a referral. When symptoms are noticed, they're often missed or misread as other conditions, and co-occurring anxiety or mood disorders can make ADHD harder to spot. Our guide to high-functioning ADHD in women covers how this plays out in adult life.

What are the main differences in ADHD symptoms in women vs. men?

In childhood, boys more often show outward symptoms like leaving their seat, while girls more often show inattention. In adults with ADHD, a 2025 study of 2,257 diagnosed patients found the symptoms remarkably similar between men and women, with only small differences.

Can women be diagnosed with ADHD as adults?

Yes. Women are more likely than men to be first diagnosed with ADHD as adults. An evaluation by a psychiatrist or another qualified clinician usually looks at current symptoms and at how things were in childhood.

Do hormones affect ADHD symptoms in women?

Researchers are beginning to study how hormone changes, such as the menstrual cycle and menopause, may affect ADHD symptoms and treatment. More research is needed before firm conclusions can be drawn.

Can ADHD be mistaken for depression or anxiety?

Yes. Trouble concentrating, restlessness, and low mood can appear in all three conditions, and they often occur together. A thorough psychiatric evaluation helps tell them apart. If you're having thoughts of suicide, call or text 988 to reach the 988 Suicide & Crisis Lifeline.
