Understanding Attention Deficit Hyperactivity Disorder

Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition affecting both children and adults. The World Health Organization recognises ADHD as one of the most common mental health conditions, impacting approximately 5% of children and 2.5% of adults worldwide.

ADHD manifests through three primary symptom categories: inattention, hyperactivity, and impulsivity. Individuals may experience difficulty concentrating during boring or difficult projects, feel overly active when expected to remain seated, or struggle with turn-taking in social situations.

Common ADHD Symptoms in Adults

Adult ADHD presents differently than childhood ADHD. While hyperactivity often decreases with age, challenges with attention and impulsivity typically persist. Adults frequently report:

1 Difficulty unwinding and relaxing during leisure time
2 Problems remembering appointments and obligations
3 Trouble wrapping up final details when a task requires organization
4 Making careless mistakes during repetitive work
5 Difficulty finding things misplaced at home or work
6 Talking excessively in social situations

Why Early Screening Matters

Many adults with ADHD remain undiagnosed, developing coping strategies that mask underlying symptoms. Without proper support, individuals may experience challenges in relationships, career progression, and mental health. Anxiety and other conditions frequently co-occur with untreated ADHD.

Taking a validated screening test serves as a great first step towards understanding your symptoms. While our assessment cannot replace evaluation by a healthcare professional, it provides valuable insights to discuss during your appointment.

The Path to Formal Diagnosis

A formal diagnosis requires comprehensive assessment by a qualified psychiatrist or clinical psychologist. The diagnostic process typically involves reviewing developmental history, current symptoms, and ruling out other conditions that may present similarly.

Following diagnosis, healthcare providers develop individualised treatment plans that may include medication, behavioural therapy, coaching, or a combination of approaches. Many adults find that understanding their ADHD traits enables them to implement effective coping strategies and thrive.

ADHD Test Questions Answered

Find answers to common questions about our screening tool and the assessment process.

What is the ADHD screening test?
Our ADHD screening tool is based on the Adult Self-Report Scale (ASRS), developed in collaboration with the World Health Organization. It evaluates common ADHD symptoms including difficulty concentrating, feeling restless, and problems with organization. The assessment takes approximately 2 minutes and provides immediate insights.
Can this test diagnose ADHD?
No. This is a screening tool, not a diagnostic test. Only qualified healthcare professionals—such as psychiatrists, clinical psychologists, or specially trained GPs—can provide a formal diagnosis of Attention Deficit Hyperactivity Disorder after a comprehensive assessment.
How accurate is the online ADHD test?
The ASRS screening tool has been validated through clinical research and demonstrates good sensitivity for identifying individuals who may benefit from further evaluation. However, many conditions can mimic ADHD symptoms, so professional assessment is essential for accurate diagnosis.
What happens after I complete the assessment?
You'll receive immediate results indicating whether your responses suggest ADHD traits. If the screening indicates moderate or high likelihood, we recommend booking an appointment with your GP or a specialist for a full assessment. You can share your results with your healthcare provider.
Is the ADHD test confidential?
Absolutely. We don't store your answers or personal information. The assessment runs entirely in your browser, and your responses remain completely private and anonymous.
Should adults take this test?
Yes, this screening tool is specifically designed for adults aged 18 and over. Adult ADHD often goes undiagnosed because symptoms may present differently than in children. Common signs include difficulty with time management, trouble wrapping up final details of projects, and feeling overly active or compelled to do things.
