Attention Deficit Hyperactivity Disorder (ADHD), once known as Attention Deficit Disorder (ADD), is a neurodevelopmental disorder defined by a consistent pattern of inattention and/or hyperactivity-impulsivity that interferes with daily functioning. Although it is not part of the formal diagnosis, emotional dysregulation is another recognized grouping of ADHD symptoms.
Globally, ADHD affects 2.5% – 6.7% of adults. Although it has long been seen as a disorder of childhood, one study found that 75% of adults with ADHD were not previously diagnosed in childhood.[1] [2]
The rates of ADHD are equal in men and women however women are significantly underdiagnosed. ADHD is perceived as a disorder affecting hyperactive boys, not girls or grown women.
However, ADHD in girls and women usually presents very differently from ADHD in boys and men.
For example, girls’ inattention shows up as daydreaming, and girls daydreaming is not a red flag for mental health. Boys’ inattention, however, shows up as not paying attention in class and is bothersome for both teachers and parents. These differences in symptom presentation is why boys get diagnosed with ADHD nine times more frequently than girls.
The sharp increase over the last few years in diagnosing ADHD in adult women is linked to women trying to get their children with ADHD help. As women walk their children through the diagnostic process, they may recognize symptoms as ones they have. The percentage of women newly diagnosed with ADHD between 23 – 49 years of age increased by almost 50% 2020 to 2022. [3]
Adult women with ADHD are more likely to get a diagnosis of Major Depressive Disorder or Bipolar Disorder instead of the correct ADHD diagnosis. These incorrect diagnoses are happening because doctors are not educated on ADHD symptoms in girls and women.
ADHD is caused by a combination of genetic, neurobiological, and environmental factors. Studies have shown that ADHD is highly inheritable, so that parents with ADHD have a 60% – 70% chance of passing ADHD onto their children. Environmental risk factors such as complications at birth or exposure to toxic materials in utero also play a role. Brain scans indicate that the prefrontal cortex is underdeveloped in men and women with ADHD helping to explain the neurological basis of ADHD symptoms. [1]
ADHD and perimenopause are connected because both conditions are strongly influenced by estrogen levels. Estrogen and dopamine, one of the neurotransmitters involved in ADHD, have a regular cycle, where dopamine increases when estrogen increases because estrogen stimulates new dopamine production.
When estrogen starts to decline in perimenopause, dopamine also declines. For women with ADHD, this makes both their perimenopause and their ADHD symptoms worse.
For example, a recent study indicates that women with ADHD suffer a 2 – 3 times increase in frequency and severity of mood changes during the menopause transition.
For women without ADHD, the decrease in dopamine can actually cause behaviours that mimic the symptoms that are seen in women with ADHD.
Women with ADHD may find it hard to focus and remember events causing challenges in all domains of life. Unfortunately, many women with ADHD are completely unaware and do not understand that their symptoms are based in their brain chemistry, not in personal flaws such as being lazy or weak-willed. This often leads to severe self-criticism, self-hatred, depression, and anxiety.
People with untreated ADHD have a higher risk of substance use, car accidents, unintentional injuries, depression, anxiety, and suicide or self-harming behaviours. In other words, underdiagnosis has significant implications, far beyond inability to focus.[4][5]
If you are experiencing any of these symptoms, talk to trusted people around you to see if they have noticed any symptoms in your behaviours (like being impulsive or overly emotional). Then talk to your healthcare provider so you can first name and then start assessing your symptoms to find solutions that work for you.

Women with ADHD often blame themselves for their shortcomings, because they do not understand that their brains are ‘neurodivergent’ and work differently from ‘neurotypical’ brains. This can lead to harmful substance use, low-self esteem, self-hatred, self-harm, social isolation, and negative self-talk.
If you know or suspect that you (or a loved one) may have ADHD, being kind to yourself (or them) as you learn to accept your symptoms is key to managing your symptoms. Talk to your healthcare provider about getting a proper diagnosis and to access ADHD resources near you.
If you’re experiencing ADHD symptoms (with or without a diagnosis), seek help and referrals from your healthcare provider. A diagnosis is required to get medications, but there are many other treatments and therapies that are part of a regular ADHD treatment plan.
Research has shown that ADHD is associated with weaker function and structure of prefrontal cortex (PFC) circuits that form connections with other regions of the brain. One of these, the prefrontal association cortex, is critical for regulating attention, behavior, and emotion, and behavioral inhibition. Proper functioning of the prefrontal cortex also depends on access to the appropriate levels of the neurotransmitters dopamine, norepinephrine, and epinephrine. [9]
Estrogen is a steroid hormone that regulates reproduction and sexual development in females. Estrogen, however, also serves as a ‘master regulator’ because it impacts many other body systems and functions.
Dopamine is a neurotransmitter that is made in your brain. It is known as the ‘feel-good’ molecule, because it is part of the brain’s reward center. When you complete a positive task or behaviour, dopamine is released, producing feelings of pleasure, satisfaction and motivation. It also plays a role controlling memory, mood, sleep, learning, concentration, movement and other body functions. [12]
Estrogen directly impacts dopamine levels in the brain. It increases the amount of dopamine available for your brain to use by boosting the amount of dopamine that is made. At the same time, it reduces the amount of dopamine that gets removed from the system through natural breakdown, and the amount that gets recycled during the reuptake process.
This connection between dopamine and estrogen is the likely root cause of some menopause symptoms including mood changes. When estrogen levels decrease, usable dopamine levels decrease. In fact, data from a recent study shows that women with ADHD suffer a 2-3 fold increase in frequency and severity of mood changes during the menopause transition. [6] [10] [13]
No, although for many years boys received almost all of the ADHD diagnoses. This is because ADHD presents differently in boys and girls. For example, hyperactivity in boys is obvious – they can’t sit still or pay attention. Hyperactive girls, on the other hand, typically internalize their hyperactivity so it shows up as a chaotic mind (which they usually hide) and / or a hyperverbality where they talk all the time.
No it isn’t. Some people with ADHD also have learning challenges (including dyslexia), but those have no impact on IQ. People with ADHD are absolutely capable of being CEOs, surgeons, academics, and entrepreneurs, just like any other non-ADHD person.
ADHD is a neurological development condition, and to receive a diagnosis, symptoms have to have been present in childhood. However, estrogen is involved in the production of the neurotransmitters that can cause ADHD symptoms, so changes to your estrogen levels can affect whether or not you experience symptoms. The root cause is different, but the effects and the symptoms show up in the same way.
Yes absolutely. If you have been formally diagnosed with ADHD, you may be prescribed medications that will impact your brain chemistry and improve your symptoms. Medication is rarely enough on its own, however, so talk therapy, especially cognitive behavioural therapy (CBT) can be very helpful as well.
