Understanding ADHD Diagnosis Criteria

If you’ve ever wondered whether you or your child might have ADHD, you’re not alone. Many people find themselves asking questions about attention, impulsivity, and hyperactivity. Understanding the ADHD diagnosis criteria can feel overwhelming, but it doesn’t have to be. We're here to guide you through the process with clear, straightforward information and gentle encouragement.

ADHD, or Attention Deficit Hyperactivity Disorder, is a neurodevelopmental condition that affects both children and adults. Getting a diagnosis can be a crucial step towards understanding yourself or your child better and accessing the right support. Let’s explore what the diagnosis involves, what to expect, and how a thorough assessment can help.

What Does ADHD Look Like?

ADHD can show up in different ways depending on the person’s age and individual traits. Some people might struggle with paying attention, others with impulsivity or hyperactivity, and many experience a mix of these symptoms. It’s important to remember that everyone can be forgetful or restless sometimes, but ADHD symptoms are more persistent and affect daily life.

For example, a child with ADHD might find it hard to sit still in class or follow instructions. An adult might struggle with organising tasks or managing time effectively. These challenges can impact school, work, relationships, and self-esteem.

Recognising these signs early can make a big difference. If you notice these patterns in yourself or your child, it might be time to consider a professional assessment.

How Are ADHD Diagnosis Criteria Defined?

The diagnosis of ADHD follows specific guidelines to ensure accuracy and consistency. These guidelines are based on the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) and are also aligned with NICE guidelines, which are recognised by the NHS.

To meet the diagnosis criteria, symptoms must:

• Be present for at least six months

• Appear before the age of 12

• Occur in two or more settings (for example, at home and at school or work)

• Interfere with social, academic, or occupational functioning

• Not be better explained by another condition

  
  

There are two main types of ADHD symptoms:

1. Inattentive symptoms – such as difficulty sustaining attention, forgetfulness, and disorganisation.

2. Hyperactive-impulsive symptoms – such as fidgeting, interrupting others, and difficulty waiting turns.

   
   

A diagnosis usually requires at least six symptoms from one or both categories for children, or five symptoms for adults.

What Happens During an ADHD Assessment?

When you decide to pursue an assessment, it’s reassuring to know that it will be thorough and tailored to your needs. Our team includes experienced clinicians such as Clinical Psychologists, Speech and Language Therapists, and Psychotherapists specialising in neurodivergence.

The assessment process typically involves:

• Detailed interviews with you or your child to understand history and current challenges

• Questionnaires and rating scales completed by you, family members, or teachers

• Observation of behaviour in settings

• Gathering information from schools or workplaces to get a full picture

• Cognitive and language testing if needed

  
  

We assess individuals from the age of 5 through to adults. For those over 11, assessments can be done face to face or online, depending on what suits you best.

This comprehensive approach ensures that the diagnosis is accurate and that any other conditions are considered. It also means we can provide personalised advice and support after the diagnosis.

Why Is a Gold Standard Assessment Important?

You might wonder why it’s necessary to have such a detailed assessment. The truth is, ADHD can sometimes be confused with other conditions like anxiety, depression, or autism. A Gold Standard assessment follows the highest clinical standards and NICE guidelines to avoid misdiagnosis.

This means:

• You get a clear understanding of what’s going on

• You receive recommendations that truly fit your needs

• You can access appropriate support, whether that’s therapy, coaching, or educational adjustments

• You have a reliable diagnosis that is recognised by the NHS and other services

  
  

Our clinicians bring many years of experience and knowledge to the table. They understand the nuances of ADHD and how it interacts with other aspects of neurodivergence. This expertise helps you feel confident and supported throughout the process.

What Support Can You Expect After Diagnosis?

Receiving an ADHD diagnosis is just the beginning. It opens the door to a range of support options designed to help you or your child thrive.

Some of the support you might explore includes:

• Psychoeducation to understand ADHD better

• Cognitive Behavioural Therapy (CBT) to develop coping strategies

• Speech and Language Therapy if communication is affected

• Educational support such as adjustments at school or university

• Parent training and support groups to help families navigate challenges

• Workplace adjustments for adults to improve productivity and reduce stress

  
  

We take time to discuss these options with you and tailor recommendations to your unique situation. Our goal is to empower you with knowledge and practical tools.

Remember, a diagnosis is not a label but a key to unlocking better understanding and support.
