Attention deficit hyperactivity disorder (ADHD) affects around 1 in 20 Australians, making it one of the country's most common neurodevelopmental disorders. The prevalence of ADHD in Australia is between 6% and 10% among children and adolescents, and between 6% and 7% across the total population. While ADHD is more commonly diagnosed in boys, it is underdiagnosed in girls and adults. In recent years, there has been a steep rise in adult ADHD diagnoses, likely due to improved access to healthcare, greater awareness of symptoms, and reduced stigma surrounding treatment.

Prevalence in Australia: 6-10% of children and 6-7% of the overall population
ADHD, or Attention Deficit Hyperactivity Disorder, is a common neurodevelopmental disorder in Australia, affecting 6-7% of the overall population. It is characterised by persistent patterns of behaviour that impact an individual's quality of life, including their ability to complete tasks, manage time, and maintain relationships. ADHD is more prevalent among children and adolescents, with an estimated prevalence rate of 6-10% in this age group. This makes it the most common neurodevelopmental disorder among young people in Australia.
The prevalence of ADHD in Australia is slightly higher than the worldwide prevalence rate, which ranges from 2-5% for both children and adults. The disorder affects around 1 in 20 Australians, and while it is more commonly diagnosed in boys, it is underdiagnosed in girls and adults. The increase in adult diagnoses in recent years is not due to a rise in the incidence of adult ADHD but rather improved awareness, better treatment options, and greater access to healthcare.
The symptoms of ADHD can vary, with some individuals experiencing inattentive symptoms, such as being easily distractible, while others exhibit hyperactive-impulsive symptoms, such as impulsivity and hyperactivity. Many people with ADHD display a combination of these symptoms. The exact causes of ADHD are not yet known, but it is understood to be an inherited disorder related to the biology of the brain.
Parents of children diagnosed with ADHD often express the need for concise, tailored, and reliable information about the disorder, its causes, and its potential impacts. This highlights the importance of providing education and support to individuals with ADHD and their families to help them understand and manage the condition effectively.

Diagnosis: 1 in 3 have ADHD as their only diagnosis
ADHD, or Attention Deficit Hyperactivity Disorder, is a common neurodevelopmental disorder, affecting around 1 in 20 Australians. It is characterised by persistent patterns of behaviour, with symptoms including inattention, hyperactivity, and impulsivity. The prevalence of ADHD in Australia is estimated to be between 6% and 10% of the population, with the disorder affecting both children and adults.
While ADHD is more commonly diagnosed in boys, it is often underdiiagnosed in girls and adults. The increase in adult ADHD diagnoses is not due to a rise in the incidence of the disorder, but rather improved awareness and better treatment options. In the past, ADHD was believed to primarily affect children and adolescents, with symptoms diminishing in adulthood. However, it is now understood that ADHD can persist into adulthood, with around 65% of those diagnosed in childhood continuing to experience symptoms as adults.
The diagnostic criteria for ADHD include a combination of inattentive and hyperactive-impulsive symptoms. To meet the criteria for a diagnosis, individuals must exhibit symptoms in multiple settings, such as home, school, or work, with an onset before the age of 12. However, it is important to note that some individuals may not come to clinical attention until later in life. The assessment process typically involves a clinical interview and standardised tests to evaluate behaviour and cognitive abilities.
Interestingly, only 1 in 3 individuals with ADHD have it as their only diagnosis. Many people with ADHD also experience other conditions, such as obstructive sleep apnoea, which can further impact their ability to concentrate. The presence of co-occurring disorders underscores the importance of comprehensive assessments and tailored treatment plans for individuals with ADHD.
While ADHD can pose challenges, effective management strategies are available. Treatment options typically include behavioural therapy, medication, or a combination of both. Additionally, lifestyle changes and support from family, friends, and professionals can make a significant difference in helping individuals with ADHD thrive and reach their full potential.

Symptoms: Inattentive, hyperactive-impulsive, or combined
While the exact number of Australians with ADHD is unknown, the condition affects about 5% of the world's population. ADHD presents in three main ways: inattentive, hyperactive-impulsive, or combined.
Inattentive ADHD
Inattentive ADHD is characterised by a lack of focus and attention, rather than hyperactivity. People with inattentive ADHD may have a limited attention span, be easily distracted, and be forgetful and prone to procrastination. They may make careless mistakes due to their difficulty in sustaining focus and following detailed instructions. They may also seem like they are not listening when someone is speaking to them and may leave projects unfinished. Their homes, cars, and workspaces may be disorganised and messy. Inattentive ADHD symptoms are far less likely to be recognised and can often be mischaracterised as laziness or apathy.
Hyperactive-Impulsive ADHD
Hyperactive-impulsive ADHD is characterised by near-constant movement and/or trouble controlling behaviour. People with hyperactive-impulsive ADHD may act without thinking, be unable to sit still, and talk excessively. They may have a hard time staying engaged and may seem to lack patience or have more energy than others. They may fidget, tap their hands and feet, or move around in their seat. Hyperactivity tends to lessen with age, so while it is less common, adults can also have hyperactive-impulsive ADHD.
Combined Type ADHD
Combined type ADHD is when inattentive, hyperactive, and impulsive symptoms are all present. It is the least common type of ADHD. People with combined type ADHD may be always on the go and have trouble staying organised. They may experience some or all of the symptoms of inattentive and hyperactive-impulsive ADHD, and some symptoms may be more prominent than others. Combined type ADHD can be categorised into different severity levels: mild, moderate, and severe.

Treatment: Behavioural therapy, medication, neurofeedback, and lifestyle changes
While there is no precise data on the number of people in Australia with ADHD, this answer will explore treatment options for the condition, including behavioural therapy, medication, neurofeedback, and lifestyle changes.
Medication
Stimulant medications are the first line of treatment for ADHD and are effective for about 80% of children with the condition. They can help improve attention, focus, and impulsivity. However, side effects may include decreased appetite, weight loss, difficulty sleeping, tics, upset stomach, changes in blood pressure, and minor growth delays. It may take up to three to four weeks to feel the full effects of these medications, and they can work for up to 24 hours. Non-stimulant medications are also an option if stimulants are ineffective or cause intolerable side effects.
Behavioural Therapy
Behavioural therapy is an effective treatment for ADHD that can improve a child's behaviour, self-control, and self-esteem. It is most effective in young children when delivered by parents or caregivers, who can learn strategies and skills to help their child succeed at school, at home, and in relationships. For children under six, the American Academy of Pediatrics (AAP) recommends parent training in behaviour management before prescribing medication. After age six, the AAP recommends medication along with behavioural therapy.
Neurofeedback
Neurofeedback is a non-pharmacological and non-invasive intervention that has shown promising results in managing ADHD symptoms in the long term without the side effects of medication. It involves computerized cognitive-based training approaches that aim to reduce ADHD core symptoms and improve neuropsychological functioning. However, the clinical value of neurofeedback is still debated, and it is currently not regulated as a clinical treatment.
Lifestyle Changes
Making positive changes to eating, fitness, and sleep habits can have beneficial effects on ADHD symptoms. A healthy diet that includes omega-3 fatty acids and micronutrients like zinc, iron, and Vitamin D can improve brain signalling and cognitive functions like focus, attention, and impulse control. Sustained exercise can decrease or reverse the negative epigenetic effects of stress or trauma, promote brain growth and efficiency, and strengthen learning abilities. Additionally, improving sleep habits can positively impact overall health and ADHD symptoms.

Impact: Can affect academic, work, and social life
ADHD, or Attention Deficit Hyperactivity Disorder, is a developmental disorder that affects both children and adults. It is estimated that around 1 in 20 Australians have ADHD, with a prevalence of 6-7% in the population. The disorder affects an individual's executive functioning, including attention, working memory, planning, sustained attention, and inhibitory control. These difficulties can impact multiple areas of life, including academic, work, and social life.
ADHD can affect academic progress and performance in school. Children with ADHD may experience challenges with concentration, focus, and completing tasks. They may also struggle with peer relationships, facing peer rejection and increased family conflict. These difficulties can lead to reduced self-esteem and conduct problems. However, it is important to note that many individuals with ADHD go on to complete school and attend university.
In the workplace, adults with ADHD may face challenges with task completion, time management, and maintaining relationships with colleagues. The disorder can impact their ability to focus, prioritise, and manage their time effectively. These challenges can hinder their career progression and job performance. However, with the right tools, strategies, and support, adults with ADHD can thrive in their careers.
Socially, ADHD can impact an individual's ability to maintain relationships and connect with others. They may experience difficulties with self-regulation, impulse control, and managing their emotions. This can lead to increased conflict and rejection and challenges in forming and maintaining friendships and romantic relationships. Social situations may become challenging, and individuals with ADHD may struggle to navigate social norms and expectations. However, with understanding and support from family, friends, and peers, social relationships can be nurtured and maintained.
The impact of ADHD on academic, work, and social life can vary from person to person. While some individuals may experience significant challenges, others may learn to manage their symptoms effectively and lead fulfilling lives. Early diagnosis, access to treatment options such as behavioural therapy and medication, and support from professionals, family, and friends can help mitigate the potential impact of ADHD on different areas of an individual's life.
