Attention deficit hyperactivity disorder (ADHD)
Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental condition that usually begins in childhood. It affects around 1 in 20 Australians.
People with ADHD may have difficulties with attention, impulsivity and/or hyperactivity. These challenges can affect daily life at school, work and in relationships.
Signs and symptoms of ADHD
Symptoms vary from person to person. A person with ADHD may:
Attention and organisation
- find it hard to maintain focus on tasks or activities
- seem not to listen when spoken to directly
- have trouble following instructions or finishing tasks
- struggle to organise tasks and manage time
- avoid tasks that require sustained mental effort
- frequently lose items such as keys or paperwork
- be easily distracted
- forget daily activities
Impulsivity and behaviour
- act without thinking or interrupt others
- have difficulty waiting their turn (for example, in queues)
- talk excessively
- interrupt or intrude on conversations or activities
- experience impatience
Hyperactivity
- fidget, squirm or find it hard to stay seated
- feel constantly restless or ‘on the go’
- have difficulty playing or doing activities quietly
Other possible signs
- mood changes or emotional ups and downs
- sleep difficulties
How ADHD is diagnosed
There is no single test for ADHD. Diagnosis is made by a qualified health professional based on a comprehensive assessment.
This may include:
- reviewing current behaviour and daily functioning
- in adults, confirming that symptoms were present in childhood
- gathering information from family members, partners, teachers or others
- ruling out other conditions that may cause similar symptoms
- considering whether alcohol or other drug use is affecting behaviour
ADHD in children may be associated with
- specific learning and language disorders
- Autism Spectrum Disorder (ASD)
- Emotional, sleep and conduct disorders.
In adults, ADHD may also be present in people with
- Anxiety disorders
- Sleep and mood disorders
- Substance use disorders
- Undiagnosed ASD
Diagnosis of ADHD is therefore never simple, and may require input from a number of clinical experts.
Treatment and support for ADHD
There is no one-size-fits-all approach. Not all patients may require medications. Treatment is tailored to individual needs and may include a combination of strategies.
Common treatment options include:
- Education, learning about ADHD to better understand and manage symptoms.
- Lifestyle changes such as regular exercise, good sleep habits, and reducing alcohol or drug use.
- Medication may be prescribed to help manage symptoms.
- Psychological therapies including behaviour therapy or cognitive behavioural therapy (CBT) to build skills such as organisation, emotional regulation and social skills.
- Family or relationship support to help those supporting the person with ADHD.
- Vocational support to assist with success at work or study.
- Support groups to connect with others with similar experiences.
A GP or specialist can help develop a personalised management plan.
