ADHD in Girls and Young Women: What It Actually Looks Like

For a long time, ADHD was understood almost entirely through the lens of hyperactive young boys who could not sit still in class. That understanding has changed significantly — but the clinical and educational systems around it have not always kept up.

Girls and young women with ADHD are still frequently missed, misdiagnosed with anxiety or depression, or told they cannot have ADHD because they are doing well enough at school. Many do not receive an identification until adolescence or early adulthood, after years of struggling without understanding why.

This post explores how ADHD actually presents in girls and young women, why it looks different, and what support can help. 

Why ADHD Is Missed in Girls:
The diagnostic criteria for ADHD were developed primarily based on research conducted on young boys. The hyperactive, impulsive presentation that most people associate with ADHD is less common in girls, who more often present with inattentive or combined type ADHD characterised by internal symptoms that are easier to overlook.

Girls are also more likely to develop masking strategies from an early age — working harder to compensate, people-pleasing, over-organising, or suppressing the signs of difficulty so effectively that neither parents nor teachers notice the struggle underneath. 

By the time many girls are identified, they have often spent years believing they are lazy, careless, or not trying hard enough. The relief that can come with understanding is real — and so is the grief.

How ADHD May Present in Teenage Girls:
For parents, some of the signs of ADHD in a teenage girl can look like:

- Losing track of things constantly despite genuine effort to stay organised
- Starting tasks but struggling to finish them, even ones she cares about - Forgetting things she was just told, including commitments and instructions
- Working best under pressure or last-minute deadlines
- Intense emotional reactions that seem disproportionate to the situation
- A constant sense of running behind, no matter how hard she tries
- Periods of hyperfocus on things she loves, alternating with difficulty engaging with anything else
- Exhaustion at the end of the school day from the effort of keeping it together
- Strong sensitivity to criticism, rejection or perceived failure
- Difficulty with time — losing track of it, underestimating it, or feeling like it moves differently for her than for everyone else

How ADHD May Present in Young Women Aged 18 to 25:
For young women in early adulthood, ADHD often becomes harder to manage as external structure falls away. The school day provided routine, reminders and accountability. University, work and independent living do not.

Common experiences include: 
- Difficulty managing deadlines, assignments and administrative tasks without external support
- Chronic disorganisation that affects relationships, finances and daily functioning
- A persistent sense of underperforming relative to intelligence and effort
- Burnout from years of compensating and masking
- Anxiety and low self-esteem as co-occurring experiences rooted in chronic self-criticism
- Difficulty maintaining relationships due to forgetfulness, emotional intensity or inconsistency
- A growing awareness that the way their brain works is genuinely different — and a desire to finally understand it

ADHD and the Hormonal Connection:
Something that is rarely discussed but genuinely important for girls and young women with ADHD is the relationship between hormones and ADHD symptoms.

Dopamine, which plays a central role in ADHD, is directly influenced by oestrogen levels. This means that ADHD symptoms can fluctuate significantly across the menstrual cycle — often worsening in the luteal phase in the days before a period when oestrogen drops.

For many girls and young women, this shows up as:
- Significantly worse concentration, emotional regulation and executive functioning in the week before their period
- Increased rejection sensitivity and emotional intensity at particular points in the cycle
- Burnout and overwhelm that seems to worsen cyclically without a clear explanation

This connection between ADHD and the menstrual cycle is an important part of understanding the full picture, and is something that can be explored as part of psychological support.

Common Co-Occurring Conditions:
ADHD in girls and young women rarely exists in isolation.

Common co-occurring conditions include: 
- Anxiety disorders, including social anxiety and generalised anxiety
- Depression and low mood, often rooted in chronic self-criticism and a sense of falling short
- Autism Spectrum Disorder — ADHD and autism frequently co-occur, particularly in girls
- Premenstrual Dysphoric Disorder (PMDD), which interacts with ADHD through the hormonal pathways described above
- Low self-esteem and confidence difficulties
- Sleep difficulties, including delayed sleep phase and difficulty switching off
- Sensory sensitivities and processing differences

Understanding these overlaps is important because it changes the therapeutic approach. Treating anxiety without understanding that it is rooted in an unidentified ADHD profile, for example, may provide limited relief. A complete picture supports more effective and targeted support.

Talking to a GP or Psychologist About ADHD:
If you recognise these patterns in yourself or your daughter, speaking to a GP or psychologist is a good first step.

It can help to:
- Write down specific examples of daily challenges rather than trying to describe things generally
- Note both the difficulties and the strengths — hyperfocus, creativity, empathy and passion are also part of the ADHD profile
- Track patterns over time, including whether symptoms worsen at particular points in the menstrual cycle
- Include observations from teachers, partners or family members where relevant

You do not need a diagnosis to begin psychological support. Therapy can be helpful at any stage — whether you are exploring ADHD for the first time, adjusting to a recent identification, or developing practical strategies for daily life.

How Psychological Support Can Help:
Psychological support for ADHD in girls and young women draws on evidence-based approaches including Cognitive Behavioural Therapy (CBT), Acceptance and Commitment Therapy (ACT) and Dialectical Behaviour Therapy (DBT).

CBT helps identify and work with the unhelpful thought patterns — particularly around self-criticism, perfectionism and shame — that develop when ADHD has gone unrecognised for years. ACT supports the development of a clear sense of values and identity that is not contingent on productivity or performance. DBT builds practical skills for emotional regulation, distress tolerance and interpersonal effectiveness, all of which are commonly challenging for people with ADHD.

Support at our practice is neuroaffirming, which means ADHD is understood as a different way of processing — not a deficit to be corrected.

Assessments:
Assessments Psychological assessments for ADHD are available for girls and young women aged 12 to 25. A comprehensive assessment can help clarify how ADHD is presenting and provide documentation for school accommodations, university disability support and NDIS purposes.

Assessment availability and fees vary depending on the type and complexity of the assessment, and some components may require an in-person component depending on individual circumstances.
