ADHD and Bipolar Disorder: Why So Many People Get the Wrong Diagnosis
30th March 2026
ADHD gets missed in women because it looks like overwhelm, not hyperactivity. Women mask it, the anxiety or low mood is what gets treated, and it often only becomes unmanageable when life asks for more than her coping strategies can carry.
But what does that actually look like in real life?
Well, if you’ve ever found yourself rereading the same email three times and still not quite understanding the context, snapping at those closest to you. Or crying, and then feeling ashamed because you’re not able to finish what you started.
Running on pure willpower alone, until you hit that mid-afternoon wall that no amount of coffee can bring you back from, this might describe at least some of your own situation.
Although, please understand this is just one snapshot of how ADHD can present, not the one singular, absolute picture.
And that’s the difficulty in both talking about and addressing ADHD in women.
There is still relatively little literature and studies specifically on females.
And much of the language that’s required to accurately describe women’s experience of this condition is still finding its way into the mainstream consciousness.
That means people such as yourself often have no words for what you’re moving through. You may be problem aware, but lack the clarity to ask the question of, ’How do I actually move past this?’
When you are able to explain your symptoms to people, you might often be labelled as simply experiencing anxiety, low mood, or just being a ‘scatty individual,’ none of which are particularly helpful for gaining a proper diagnosis and the support that you need, which is going to help you move on to the next stage of your life.
What does ADHD look like in adult women?
The most common presentations of ADHD in women are usually inattentiveness, accompanied by an inner restlessness, as well as intermittent bouts of emotional dysregulation, which you could also read as emotional turbulence if that term is unfamiliar to you.
Now, it’s important to mention here that the core traits of the condition are the same as in men. However, when it comes to diagnosing ADHD in women, some of these traits, especially the emotional dysregulation, are easy to dismiss with the stereotype of women naturally being more emotional than their male counterparts. Hence, bypassing a very real need for support.
Inattention that passes for daydreaming or disorganisation
In the official model of ADHD presented by the DSM-5, there are three presentations. The first is predominantly inattentive. The second is predominantly hyperactive and impulsive, and the third is combined.
But here’s the thing, women experience inattention just as much as men do. What does differ, is that they are far less likely to show the outward hyperactivity or signs of impulsivity that serve as the biggest red flags for the condition.
This is why the predominantly inattentive presentation so often gets missed. However, this is an issue not just for women, but also for quieter individuals in general, who slip under the radar, because of the sophisticated masking strategies they develop.
Oftentimes, people with inattentive ADHD can be seen as capable and very conscientious of their surroundings, their responsibilities, and others’ needs. They can be very empathetic and giving towards others, but only just about holding it together internally.
Here’s what some of the symptoms of inattentiveness look like.
- Executive dysfunction: Executive dysfunction is really what defines much of ADHD, because it is responsible for so much of the capacity to choose, and also to remain engaged with choice as an ongoing action or activity. In a practical setting, that might mean knowing that there are many things to do but struggling to initiate any of them, or even initiating many things at once but then struggling to see those things through to completion. It can and often does work both ways.
- Time blindness: If you drift into deep inattentiveness, that daydreaming quality can cause you to dissociate from the real-world, linear expression of time, which can make an hour absorbed in your own world feel like 10 minutes. This then causes you to feel like you’re in a perpetual state of needing to catch up, because, ‘Where did all that time go!? Damn I need to catch up!’
- In relationships: Another behavioural piece that can fly under the radar is an inability to reply to messages on time, or even to reply to messages at all. This can then lead to putting the task off for an even longer period, because any message then requires an apology, which brings about an embarrassment and a shame cycle. That cycle can perpetuate feelings of isolation, inadequacy and unworthiness.
What others see: Women who might exhibit some of these behavioural tendencies are often otherwise extremely well-meaning people who are well liked within their social circle. Some of these traits might be hard for others to pick up on, or are otherwise excused as being part of someone’s personality, as they don’t cause any intentional outward harm to others. Therefore, they’re never flagged.
Restlessness that turns inwards, and the exhaustion that follows
Below is a common cycle which many women can find themselves in to go undiagnosed with ADHD into their adult life:
- Internal hyperactivity: This kind of internal hyperactivity can be characterised as having about 20 Google Chrome tabs open at once with all of them playing audio at the same time. This is often attributed to taking on too much, which can lead to talking a lot, and an inability to switch off in the evening.
- Masking and burnout: Over time, constantly masking, covering mistakes and conforming to social etiquette is deeply depleting, and after years of compensating it often ends in burnout.
- Wired but tired: ADHD fatigue is something we often see described as hitting a proverbial wall in the mid afternoon. But then can also show up in the evening when the body is tired but the mind wants to keep going, so there’s difficulty both getting to sleep and getting high-quality restorative deep sleep. Tired, but wired.
Emotional intensity, masking and “high-functioning” ADHD
Emotional dysregulation: Many women with ADHD can often be quick to feel their emotions and equally quick to hide their reactions. That can look like a sudden, sharp response to criticism, some tears, or maybe a bout of irritability that comes and goes. Afterwards, it can leave them feeling like the only person who has ever reacted that way. She may then replay the moment over and over, internalising the embarrassment.
Masking: ADHD masking in women is essentially a way of overcompensating for struggles in social etiquette, meeting expectations, or otherwise presenting as emotionally regulated. This can take on the expression of perfectionism, people-pleasing, or internally scripting before activities or meeting people out in public.
“High-functioning” ADHD: A popular phrase, though not a formal diagnosis. A 2024 review pooling 52 studies found only small differences: adult rating scales rated men’s inattention as somewhat more severe, but clinical interviews found no significant sex differences.
Why is ADHD in women so often misdiagnosed?
One of the primary reasons ADHD in women is so often misdiagnosed is the overlap between anxiety and low mood, meaning the more visible psychological symptoms are recognised, whilst the day-to-day symptoms of executive dysfunction are much harder to identify.
To put the numbers in perspective, a 2026 study of GP records across England found ADHD recorded in 1.48% of males compared with 0.91% of females, and diagnosis rates fell well below expected prevalence in every age group. Among 18 to 24 year olds, that shortfall was around 29% for men but 59% for women. Many of those undiagnosed women are not missing symptoms. Their symptoms are simply being read as something else.
NICE confirms that ADHD is generally thought to be under-recognised in both girls and adult women. One of the trickiest conditions to separate it from is borderline personality disorder. The table below illustrates the main drivers, triggers and general solutions for each condition.
| ADHD | Anxiety | Depression | BPD | |
| What drives it | Differences in attention, planning and emotional regulation | Worry about threat or things going wrong | Low mood and loss of interest | Intense emotional sensitivity, often in relationships |
| Typical trigger | Boredom, overload, deadlines, interruption | Feared situations or outcomes | Can arrive without a clear trigger | Perceived rejection or abandonment |
| Pattern over time | Present since childhood, in all areas | Often comes in waves | Episodes lasting weeks or longer | Long-standing pattern across relationships and self-image |
| What tends to help | ADHD-informed support, strategies and sometimes medication | Talking therapy, sometimes medication | Talking therapy, sometimes medication | Specialist talking therapy |
The takeaway: One of the biggest overlapping symptoms is overwhelm. However, it isn’t necessarily the case that all overwhelm has the same root cause. I.e. overwhelm is considered more of a general pattern, which requires the discernment of a trained clinician to understand exactly where it is arising from. Without this, it can lead to the ongoing cycle of continually treating symptoms with the wrong approach which often leaves the women feeling like, “therapy just doesn’t work for her.”
Anxiety and depression
Anxiety and depression are the most common conditions that ADHD is mistaken for because of the very real symptom overlap that exists. And part of this can be attributed to the fact that untreated ADHD can feed into pre-existing anxieties. Many women often describe themselves feeling like they’re in a constant catch up – a hamster wheel type lifestyle.
In a small 2026 UK study of women with autism and/or ADHD, 12 of the 19 who disclosed an earlier mental health diagnosis disagreed with it, 4 agreed and 3 did not say. The authors said the disagreement was particularly noticeable among women diagnosed with anxiety and depression.
I’ve noticed in my own personal clinical practice, it helps immensely to ask what a feeling is attached to rather than assuming a template based diagnosis based on symptoms. This is the type of person-centred approach that’s required to treat conditions where there is very clear overlap between multiple different symptom sets. Because worry attached to an outcome points to one root cause, whilst an overload from competing demands points in a very different direction.
ADHD or BPD? How they differ, and whether you can have both
ADHD and BPD can look alike in their presentations, because both conditions often involve quite intense emotional dysregulation coupled with a tendency towards impulsivity. However, they are separate conditions, though it’s entirely possible to have both.
The key differentiator to bear in mind is how each one develops. ADHD is now officially known as a neurodevelopmental condition by the DSM-5 and ICD-11. This means, it will have been present since childhood and will show up in multiple areas of daily life. BPD on the other hand, is a personality disorder which is often linked to childhood trauma, most often involving neglect and abandonment.
The unfortunate truth about adults who live with undiagnosed ADHD, is that they will often go on a journey of collecting other psychiatric diagnoses, which may have little to no bearing on their actual circumstance.
This can often go on for years, before they are able to find the correct answer for their situation, due in large part to the significant overlap in the emotional landscape of each condition.
This means there needs to be a thorough and considered assessment on the part of the clinician, to consider the potential of both, either in isolation or as a comorbid presentation.
When it’s more than one thing
Something else which is worth relating to you, is that ADHD can often co-occur alongside other conditions that we haven’t mentioned here as well. These include obsessive compulsive disorder, as well as a multitude of eating disorders. Individually, each of these may explain a part of the picture of ADHD, but not provide the complete answer that’s required.
Being able to distinguish ADHD and OCD in women, for example depends largely on whether the repetitive behaviours are driven by distress and ritual, or by distraction and seeking novelty. Again, autism and ADHD can also overlap so there is a separate assessment needed in cases where both may be a potential diagnosis.
Why does ADHD often show up later for women?
ADHD can often show up later in life for women, due to changes in circumstance and the levels of responsibility that they might be asked to take on. This can often happen in many areas of life at once: at work, maybe becoming a mother, or even entering the perimenopause phase.
All of these can challenge women and see their coping strategies, which could hold most of their life together, begin to come apart at the seams. This can see them having multiple breakdowns in several areas of their life at once, which can then lead to asking the question, ‘Why me? Why now? Why is all this happening to me?’
Puberty and school
Entering puberty and secondary school can also be a key point in many young women’s lives where the need for greater organisation can outstrip their coping mechanisms. This means, the girl who may previously have coped through being extra diligent, yet struggling in silence may suddenly find themselves overwhelmed beyond their capacity to perform. A 2024 Lancet Psychiatry review found that females are diagnosed less often than males especially in childhood and are also less likely to receive any meaningful support as a result.
Motherhood, when the scaffolding comes down
Motherhood also brings all its own unique challenges. And for much of the same reasons as in puberty, but in a very different context. That reason is a drastic change of routine, in which greater organisation is required again. This time, however, it is accompanied by broken sleep and the mental/emotional load of both planning for another person’s care as well as the daily upkeep of devotional presence, all while looking after one’s own needs, which were already difficult enough to hold.
A 2026 systematic review of 10 studies found women with ADHD had roughly 1.8 to 2.6 times the odds of perinatal depression. We should add that most of the studies were of medium quality and the authors did call for more high-quality research. That does not mean motherhood causes ADHD. It suggests ADHD may make the perinatal period harder, and also expose the tendencies that were successfully masked in earlier life.
Hormones: periods, PMDD and perimenopause
Another significant area that can often be overlooked is the role hormones play in how ADHD can be experienced. For instance, premenstrual dysphoric disorder (PMDD), which is a severe premenstrual mood disorder, can overlap with ADHD traits.
It primarily manifests as intense emotional and physical symptoms in the week or two before a period. These symptoms usually ease a few days after bleeding starts. The NHS describes the condition as being like PMS but more intense – that is, intense enough to make work, socialising and relationships difficult.
If this sounds like something you may be experiencing, it can help to track your symptoms across your cycle. Many women notice that focus and mood feel easier in the follicular phase, between the start of a period and ovulation, and harder in the late luteal phase, the days just before a period. This is consistent with how hormone shifts can affect ADHD symptoms. Just a few weeks of notes can give a clinician something concrete to work with, and provide you with better support.
A 2025 UK survey of 715 young women found provisional PMDD in 31.4% of those with a self-reported ADHD diagnosis, against 9.8% of those without, although the research is admittedly quite thin at present. In perimenopause, a 2025 study of 5,392 Icelandic women found those with ADHD reported higher symptom scores, highest at ages 35 to 39. It was cross-sectional, so it cannot show cause.
In a King’s College London study of 656 women aged 45 to 60, an ADHD diagnosis did not directly raise menopausal complaints, but higher ADHD symptom scores were linked to worse ones.

How is ADHD in women diagnosed?
If you’re a woman who is looking to gain an accurate clinical diagnosis for ADHD, it’s important to know what the process looks like.
A proper assessment is carried out through a structured clinical assessment.
What it is not, is an online quiz that you may have taken in the past. Although they do have their own value in helping you begin asking the question around whether you have ADHD or not.
NICE guidance states that any assessment should be carried out by an appropriately qualified clinician with the relevant training that’s required in ADHD to give a full and proper diagnosis.
What this looks like in a real-world context is the following:
The assessment will look at your current difficulties alongside your developmental and psychiatric history to answer the question of whether your symptoms are affecting you in more than one area of your life.
A good assessment will also screen you for conditions that look similar but have different underlying causes, which matters a great deal if you’re someone who may have been misdiagnosed in the past.
On the NHS, you can ask your GP to refer you, and waits can be long in many areas.
Right to Choose may allow you to choose a different provider in England, and some people go privately.
Treatment for ADHD in women can include psychoeducation, practical strategies, talking therapy and medication, depending on the person.
How We Can Help
Finally, I want to remind you, that an ADHD diagnosis is absolutely not a judgement on you or your character. Alongside the genuine struggles we talked about here, the reality is that many women with ADHD are incredibly creative, quick-thinking, deeply empathetic and resourceful. An accurate diagnosis helps you work with that brain, not against it.
If anything in this article has resonated with you, and you would like to talk more about exploring what it means to get an accurate diagnosis, whether it be related to ADHD or part of the greater picture of understanding everything you’re moving through, we would love to help guide you through that process.
