How Do I Check If I Have ADHD?

If you’ve been asking “do I have ADHD?” or searching how to check if I have ADHD, you’re not alone. Many adults notice lifelong patterns of distraction, impulsivity, or organisation difficulties and wonder whether ADHD could be the reason. This guide walks you through how to recognise common traits, use screening tools safely, and take the right next steps toward a formal assessment if needed.

Why check in now?

• Understanding whether ADHD explains persistent struggles can unlock effective support and practical strategies.
• Early recognition helps with workplace adjustments, relationship improvements, and better mental health.

What to look for first: common traits and signs

ADHD presents differently in everyone, but common signs in adults include:

• Persistent difficulty focusing on boring or repetitive tasks.
• Trouble organising tasks, meeting deadlines, or managing time.
• Chronic procrastination or avoidance of important tasks.
• Frequent forgetfulness (appointments, keys, bills).
• Impulsivity in decision-making or interrupting others.
• Restlessness, difficulty relaxing, or feeling mentally overstimulated.

If several of these describe you and they interfere with daily life or started in childhood, it may be worth exploring further.

Using screening tools: ADHD self test and checklists

A sensible next step is an ADHD self test or screening questionnaire. These tools are designed to quickly highlight common symptoms and help you decide whether to seek a full assessment.

Where to try a screening tool

• NeuroDirect screening page that can help you check for common traits.
• The World Health Organization’s ASRS (Adult Self-Report Scale) is a widely used screener in research and clinical practice.

How to use a screener effectively

• Be honest and consider your typical behaviour across different settings (work, home, school-aged years).
• Remember screeners are not diagnostic; they only indicate whether further evaluation is warranted.
• Take note of questions that trigger strong agreement—these are the patterns to discuss with a clinician.

Are online ADHD tests accurate?

Short answer: they can be useful, but they are not definitive.

• Online ADHD tests and screeners (like the ASRS) are helpful for identifying patterns consistent with ADHD and for raising awareness. They have reasonable sensitivity for flagging possible ADHD but vary in specificity: that means they can suggest ADHD when other issues might be responsible.
• Conditions such as anxiety, depression, sleep problems, thyroid issues, and certain medications can mimic ADHD symptoms.
• Online tests do not evaluate developmental history, rule out other causes, or assess functional impact—key elements in the ADHD diagnosis process.

Use online tests as a screening step, not a final answer. If a screener suggests possible ADHD, the next step is a clinical assessment.

What happens after an ADHD screening?

If your screening indicates likely ADHD, these are typical next steps:

• 1. Talk to your GP or primary care clinician
  • Bring results of your self-test and examples of symptoms and how they affect daily life.
  • Your GP can rule out other medical causes, review medications, and refer you for specialist assessment if appropriate.
• 2. Specialist assessment

  ADHD screening adults usually leads to an assessment by a psychiatrist, clinical psychologist, or an ADHD specialist. You can find local specialists via the NeuroDirect directory.The specialist will take a developmental history, ask about symptoms across childhood and adulthood, gather collateral information (school reports, partner/family observations), and consider other mental health conditions.

• 3. Diagnosis and care planning

  If criteria are met, you’ll receive a formal diagnosis and a personalised care plan that may include medication, psychological therapies, coaching, and workplace or educational adjustments.

Do I need a formal diagnosis?

A formal diagnosis is not mandatory for everyone, but it often helps:

Benefits of a formal diagnosis

• Access to evidence-based treatments, including medication when appropriate.
• Eligibility for workplace adjustments, educational accommodations, and certain support services.
• Clearer understanding of personal strengths and challenges; validation that helps many people make practical changes.

When you might skip formal diagnosis

• Some people use self-management strategies successfully without pursuing a diagnosis, especially if symptoms are mild and functioning is good.
• However, if symptoms are significantly affecting work, relationships, or wellbeing, a formal diagnosis offers clearer and often more effective options.

How clinicians assess ADHD: the diagnosis process

• A detailed clinical interview covering current symptoms, childhood behaviour, medical history, and impact on daily life.
• Standardised questionnaires (like the ASRS) completed by you and sometimes by close contacts.
• Cognitive or neuropsychological testing in some cases, to assess attention, memory, and executive function.
• Screening for other mental health conditions and medical causes.

Expect the assessment to take time—accurate diagnosis involves gathering history, observation, and sometimes records from childhood.

Treatment options and practical supports

After diagnosis, treatment plans are tailored to your needs and may include:

• Medication: stimulant and non-stimulant options can reduce core symptoms for many adults.
• Psychological approaches: cognitive-behavioural therapy (CBT) adapted for ADHD, coaching, and skills training.
• Practical strategies: structured routines, time management tools, technology aids, and environmental adjustments.
• Workplace or educational accommodations: flexible deadlines, quiet spaces, or adjusted workloads.

Where to get help and reliable information

• Speak to your GP as a first step. They can refer you for specialist assessment.
• Find a specialist through the NeuroDirect directory.
• For official guidance on diagnosis and services, see the NHS guidance on ADHD diagnosis and the CDC guidance on ADHD diagnosis.

When to seek immediate support

If ADHD-like symptoms are part of severe depression, self-harm, panic attacks, or if you have thoughts of harming yourself or others, seek urgent medical help or contact emergency services right away.

Summary: practical steps to check if you have ADHD

• 1. Reflect on lifelong patterns and how symptoms affect your life.
• 2. Complete an online ADHD self test or screener to identify likely traits (use tools such as the NeuroDirect screening page).
• 3. Discuss results with your GP and ask for a referral if appropriate.
• 4. Attend a specialist assessment for a full ADHD diagnosis process if recommended.
• 5. If diagnosed, work with clinicians to build a personalised plan combining treatment and practical supports.

Discovering whether you have ADHD can be empowering. A screening test is a useful first step, but accurate answers usually come from a thorough clinical assessment that considers your history and current functioning. If your symptoms are affecting your life, reach out — help and effective strategies are available.
