ADHD (Attention‑Deficit/Hyperactivity Disorder) is a common neurodevelopmental condition. Around 5–8% of children and ~2.5–3% of adults meet criteria worldwide, and many are not identified until later in life. Access to care varies between regions and services.

ADHD isn’t a flaw—it’s a natural variation in how the brain regulates attention, motivation, and self‑management. Traits such as inattention, impulsivity, restlessness, and emotional intensity can make daily life overwhelming, yet many people also bring remarkable creativity, curiosity, hyperfocus, resilience, and empathy.

Quick facts about ADHD

• ADHD often begins in childhood and can persist into adulthood, though how it presents can change over time.
• Prevalence is ~5–8% in children and ~2.5–3% in adults internationally.
• In adults, inattention and executive function differences (planning, organisation, working memory) often predominate; hyperactivity is usually less visible.
• Anxiety and mood conditions commonly occur alongside ADHD and can mask or compound symptoms—one reason thorough assessment matters.

What is ADHD

ADHD affects people across all ages, cultures, and backgrounds. It is characterised by differences in how the brain initiates, sustains and switches attention, manages impulses and energy, and coordinates executive functions such as planning and working memory.

People with ADHD may experience challenges with sustaining or directing attention (especially for routine, unstimulating, or delayed-reward tasks), starting, switching, or completing tasks, organisation and planning, impulse control, and time, sleep, or emotional regulation.

Developing a clearer understanding of both strengths and challenges can be empowering. A formal assessment clarifies whether ADHD is present and what supports or treatments may help.

How ADHD can show up across life

Children may present with distractibility, high activity, impulsivity, and big emotions.
Teens often face time‑management challenges, inconsistent performance, and restlessness; rising expectations can unmask difficulties.
Adults commonly report difficulties with planning and organisation, task initiation and completion, working memory and emotional regulation—even when outward hyperactivity is minimal.

Who gets missed (and why)

Women and people who were assigned female at birth can have more inattentive or “quiet” profiles and may mask symptoms, delaying recognition until transitions such as parenthood, job change, or perimenopause.
Māori and Pacific peoples face systemic health inequities and barriers to culturally safe, accessible care—services must honour Te Tiriti o Waitangi and whānau‑centred approaches.
High‑achieving or anxious adults may use anxiety and perfectionism to compensate for executive skill gaps, masking ADHD until coping strategies stop working.

ADHD and anxiety: how they overlap

ADHD and anxiety frequently co‑occur. Anxiety may arise from repeated executive challenges or become the “engine” for task completion; conversely, untreated ADHD can make anxiety harder to manage. Good assessments separate overlapping features and plan both ADHD supports and anxiety care.

Getting assessed: what to expect

A high‑quality ADHD assessment typically includes a clinical interview (history from childhood to now, covering strengths and challenges), standardised rating scales completed by you and, where possible, a person who knows you well, screening for co‑occurring conditions (anxiety, mood, learning, sleep and physical health contributors), differential diagnosis to rule in/out other explanations (e.g., sleep disorders, thyroid conditions, mood disorders), and a feedback session with a written summary and a clear plan for supports and reasonable accommodations.

Helpful to bring: school reports (if available), past assessments or reports, medications tried, examples of tasks that are hard or easy, and (with permission) a support person for collateral information.

Self‑screening (optional): Adults sometimes begin with the ASRS 6‑item screener to determine whether further assessment is warranted. It is not a diagnosis.

The strengths of ADHD

Many people with ADHD describe enduring strengths, including creativity (seeing patterns and options others miss), curiosity (a drive to explore, learn, and question), hyperfocus (deep immersion when interest is sparked), and resilience and empathy (navigating headwinds builds adaptability and attunement to others).

Anxiety New Zealand’s Adult ADHD Assessment Service (25+)

Anxiety New Zealand offers a limited number of adult ADHD assessments for people aged 25 years and older. Assessments are available in person at our St. Luke's clinic (Auckland) and online for eligible clients. A full assessment includes Part 1 (always first) and Part 2; the pathway is the same for current or past Anxiety NZ clients. For cost and availability, see our Assessment details page.

How our assessment works (overview):
Part 1 – Initial assessment: history, rating scales, screening for co‑occurring conditions and differential diagnosis.
Part 2 – Diagnostic decision and plan: feedback; tailored strategies; discussion of therapy, coaching, and—if appropriate—medicine options with your prescriber.

Context in Aotearoa (from 1 Feb 2026): Within their scope, more specialist GPs and nurse practitioners can now assess adults and initiate stimulant medicines; new services will roll out gradually, and not every practice will offer this immediately. Your GP remains your first port of call for local pathways.

ADHD Treatment and Supports: a multimodal plan

Education and skills: ADHD‑informed CBT, coaching/skills training, environmental modifications, and digital tools such as timers, visual planners and task batching can help.

Medicines in NZ: publicly funded options include methylphenidate, dexamfetamine, and lisdexamfetamine; atomoxetine is a non‑stimulant option. Medicine decisions consider benefits, side effects, co‑existing conditions, and your preferences. Prescribers monitor cardiovascular and mental health, dose, and response, and will discuss any risks (e.g., sleep, appetite). Global supply pressures have occurred—Pharmac actively manages brands and alternatives.

If you already have a diagnosis: Talk with your GP about ongoing care under the 2026 rules—some practices will offer assessment/initiating prescriptions; others will collaborate with specialists or refer for complex needs.

Work and study: your rights and practical supports (NZ)

At work: NZ law protects people from disability discrimination and expects reasonable accommodation (for example, flexible hours, clear written tasks, quiet spaces, assistive tech) unless it causes unjustifiable hardship. See guidance from the Human Rights Commission/Ombudsman and Employment NZ.

Tertiary study: Most universities and polytechnics have Accessibility/Disability Services—ask about exam supports, note‑taking, and study‑skills coaching.

ADHD, Women and midlife

Perimenopause can intensify ADHD‑related brain fog, working‑memory lapses, and emotional reactivity. If symptoms shift in your 40s–50s, it’s reasonable to seek an ADHD‑informed review; care may include ADHD strategies, anxiety support, sleep optimisation, and (via your GP) menopause management.
