Female ADHD: Why It Looks Different and Why It’s So Often Mistaken for Anxiety

An International Women’s Day perspective from Montrose Health Group

For many years, ADHD was framed as a childhood condition affecting predominantly hyperactive boys. As a result, generations of girls and women were overlooked. On International Women’s Day, it is important to spotlight a critical and often under-recognised issue in women’s mental health: the distinct presentation of ADHD in females, and the frequency with which it is misdiagnosed or overlooked.

At Montrose Health Group, we see firsthand how delayed recognition of ADHD can affect educational attainment, career progression, relationships and overall wellbeing. Increasing awareness is more than just refining healthcare, it's recognising a whole group of women and looking at how we can support them.

Why ADHD Looks Different in Women

ADHD is a neurodevelopmental condition characterised by inattention, impulsivity, and hyperactivity. In females, these features are more likely to be internalised.

Rather than disruptive behaviour, women often present with:

• Persistent inattention and distractibility

• Disorganisation and difficulty initiating tasks

• Internal restlessness

• Emotional intensity

• Chronic overwhelm

Because these symptoms are less visible, they are often attributed to personality, stress, or anxiety.

Why It Is Mistaken for Anxiety

Executive Overload

Difficulties with planning, prioritising, and time management create a constant sense of falling behind. This can manifest as worry, sleep disturbance, and rumination — clinically resembling generalised anxiety.

Compensatory Perfectionism

Many girls develop coping strategies such as over-preparing, excessive checking, and people-pleasing. While adaptive in the short term, these strategies increase internal strain and reinforce an anxiety narrative.

Emotional Dysregulation

Heightened sensitivity, rapid mood shifts, and rejection sensitivity are common in ADHD but frequently mislabelled as anxiety or mood disorder.

Anxiety and ADHD often co-exist. However, when executive dysfunction is the primary driver, treating anxiety alone may not resolve impairment.

The Impact of Delayed Recognition

Missed ADHD can lead to:

• Recurrent anxiety and depressive episodes

• Burnout

• Low self-esteem

• Occupational underperformance relative to ability

• Relationship strain

Many women describe diagnosis as clarifying rather than defining — it reframes longstanding difficulties through a neurodevelopmental lens.

A Clinically Led Approach

Accurate diagnosis requires comprehensive assessment, including:

• Developmental history

• Functional impairment across settings

• Exploration of masking and compensatory strategies

• Screening for comorbid conditions

This ensures appropriate, evidence-based treatment tailored to the individual.

Advancing Women’s Mental Health

On International Women’s Day, improving recognition of female ADHD is not simply about diagnosis — it is about equitable care. When clinicians understand gender-specific presentations, women receive earlier identification, targeted intervention, and meaningful improvement in functioning and wellbeing. If persistent anxiety is rooted in chronic overwhelm, disorganisation, or lifelong attentional difficulties, specialist assessment may provide important clarity.
