At Healios, an online ADHD assessment for an adult is delivered through a series of structured video appointments with specialist clinicians.
These assessments aim to understand attention, activity levels, impulsivity, and everyday challenges. While some adults receive a formal ADHD diagnosis, others may not meet the diagnostic criteria. Even if a diagnosis is not given, the assessment can provide valuable insights, practical strategies, and guidance to help manage challenges at work, home, and in daily life.
Many adults explore an ADHD assessment after noticing differences in how they focus, organise tasks, or manage responsibilities. Some adults appear restless or impulsive, while others primarily struggle with attention or planning. We also recognise that many adults with ADHD have learned to mask and internalise challenges, and our skilled clinicians are trained and experienced in unpicking this and ensuring an accurate diagnostic outcome. The assessment process can bring clarity, reassurance, and practical advice, regardless of whether a diagnosis is given.
We know this process can feel overwhelming. At Healios, we aim to make ADHD assessments clear, supportive, and compassionate, helping individuals thrive.
What is ADHD?
Attention Deficit Hyperactivity Disorder (ADHD) is a neurodevelopmental condition that affects attention, activity levels, emotional regulation and aspects of behaviour. Experiences of ADHD vary widely among adults, with some showing primarily inattentive signs and others more hyperactive or impulsive behaviours.
ADHD is understood to develop through a combination of genetic, biological and environmental influences. Research in this area is ongoing, and experiences of ADHD vary widely from person to person. ADHD can affect daily life, including work, relationships, organisation and time management. With the right guidance and support, individuals can develop strategies to manage these challenges effectively
What are the signs of ADHD in adults?
ADHD symptoms are often grouped into two categories: inattentiveness and hyperactivity/impulsiveness. Some adults show more signs in one area, while others may experience a combination of both.
Signs of inattentiveness may include:
- Difficulty focusing or staying on task
- Forgetfulness or missing details
- Problems with organisation and time management
- Frequently switching between tasks or leaving tasks unfinished
Signs of hyperactivity and impulsiveness may include:
- Feeling restless or constantly “on the go”
- Fidgeting or difficulty sitting still
- Talking excessively or interrupting
- Acting without considering potential consequences
Because these behaviours can also appear in adults without ADHD, it is important to choose an experienced, accredited provider. A diagnosis is only made when symptoms have been present over time, across multiple settings, and clearly impact daily life.
Accessing ADHD assessments at Healios
Healios provides online ADHD assessments for adults across the UK. We work in partnership with NHS services where appropriate, and also provide private assessments for adults seeking support independently.
If Healios is available in your area, your local NHS service may refer you for an assessment. Private self-referrals are also accepted from Melios, part of the Healios family.
What is an online ADHD assessment?
An online ADHD assessment at Healios follows a similar structure to in-person assessments but takes place over secure video calls.
Clinicians use our digital platform, Panacea, where adults can:
- Join video appointments
- View session notes
- Manage appointments
- Invite family members or supporters to participate, if desired
Completing assessments at home can help individuals feel more comfortable, while giving clinicians a clear understanding of everyday behaviours and routines.
How do online ADHD assessments work at Healios?
Step 1
Complete questionnaires
Before the assessment, clients complete a small number of online questionnaires about their attention, organisation, and daily challenges. Clinicians will also request input from someone who knows the adult well, such as a partner, family member, or colleague.
Step 2
Attend assessment sessions
Online ADHD assessments usually include two key appointments:
- Initial session
Meet your clinician to discuss concerns, explain how the assessment works, and review your personal, educational, and work history.
- ADHD assessment session
This session typically lasts around two hours and involves structured conversations to explore attention, organisation, impulsivity, and everyday functioning. Clinicians also consider whether other mental health or neurodevelopmental conditions could be contributing to difficulties.
Step 3
Receive the outcome and discuss next steps
After the appointments, the clinician meets with a multidisciplinary team to review findings and agree on an outcome. A detailed report is prepared, and a feedback session is arranged to explain the outcome, answer questions, and discuss strategies, therapies, or medication options where relevant.
What happens next?
Receiving the outcome of an ADHD assessment can be an important moment. Whether a diagnosis is given or not, Healios ensures adults feel supported, informed, and clear about next steps.
If you receive an ADHD diagnosis
A diagnosis can help you and those around you understand your strengths, challenges, and needs. It can also guide access to workplace adjustments, therapies, or practical strategies for daily life.
Where available, Healios provides post-assessment support for adults. These online sessions allow you to explore the diagnosis, ask questions, and develop strategies to manage attention, organisation, and impulsivity.
If NHS-funded post-assessment support is unavailable in your area, we provide information about other helpful services and charities. Private post-assessment support, including guidance on ADHD medication, is also available.
If you do not receive an ADHD diagnosis
Not receiving a diagnosis does not mean your experiences are less valid or that support is unavailable. Some adults may have signs or challenges that do not meet the threshold for ADHD.
In these cases, clinicians provide a detailed report explaining the findings and reasoning. Recommendations may include:
- Further assessments (e.g., for anxiety, depression, or other neurodevelopmental conditions)
- Practical strategies for organisation, focus, and daily routines
- Signposting to local services, charities, or support organisations
Clinicians take time to discuss the findings, helping you understand the results and available support options.
Beginning the process of an ADHD assessment can feel daunting, but you do not have to navigate it alone. Healios provides high-quality, compassionate care designed to help adults feel understood, supported, and equipped to thrive.
