We provide neurodiversity-affirming assessment for adults seeking late diagnosis of autism, ADHD and AuDHD.

Understanding

Neurodivergence in adulthood

Most of us grew up in an era where far less was known about autism and ADHD. If you learned how to meet expectations, perform well or mask differences, then your parents and teachers may not have seen your internal struggles or sense of shame.

Many adults are unaware that they’re neurodivergent – but they do know that certain aspects of life feel hard to navigate. You’ve spent years coping, adapting and pushing through, possibly being diagnosed with conditions like anxiety, OCD or insomnia. If everyday life still feels draining, it’s possible that the real underlying driver is undiagnosed neurodivergence.

Eventually, you may seek a neurodiversity-affirming assessment because you:

  • are experiencing persistent difficulty with focus, attention, organisation and life admin 
  • feel emotionally overwhelmed or highly sensitive to perceived criticism
  • have experienced difficulties in your job or relationships
  • sense that long-standing coping strategies are becoming unsustainable as demands increase (e.g. parenthood)
  • have a child or family member who has been diagnosed, and realise that you share many similar characteristics!

Over the years, you may have internalised negative messages about yourself despite working hard to meet expectations. A diagnosis can bring both a sense of loss for what was missed and relief in finally understanding how your brain works. Late diagnosis support can help you learn new strategies that work with your neurodivergence not against it.

Assessment considers not only your current challenges, but also how patterns have shown up across work, relationships and daily life over time. This is particularly relevant for adults seeking understanding around AuDHD, where autistic and ADHD traits may overlap or interact in complex ways.

Understanding

High-Masking Presentations

High-masking autism can look like:

  • carefully monitoring social interactions, including rehearsing or replaying conversations
  • suppressing sensory needs
  • maintaining high levels of performance despite the cost to your wellbeing

Our in-depth assessments include standardised autism tests alongside deeper questioning to understand the:

  • strategies you’ve developed to manage social, sensory or cognitive demands
  • effort required to sustain these strategies
  • impact on your energy, wellbeing and identity over time

Adult ADHD support

Adults with ADHD often describe difficulties with focus, time management, task initiation and emotional regulation, even when they are highly capable or successful. 

These challenges can be compounded by the heightened emotional intensity of rejection-sensitive dysphoria (RSD). 

Adult ADHD support focuses on understanding how attention, executive functioning and emotional responses interact in daily life, rather than reducing experiences to symptoms alone.

Assessment may explore:

  • patterns of motivation, procrastination and overwhelm
  • emotional responses to perceived criticism or rejection
  • the sustainability of current coping systems
  • strengths alongside areas of difficulty

Work, relationships and daily life

You may expend significant energy navigating environments that were not designed with your needs in mind. Assessment can support clearer conversations around identity, capacity and navigating workplace accommodations.

We also consider how neurodivergence intersects with:

  • career demands and burnout
  • communication styles and relationships
  • parenting and family dynamics
  • self-understanding and identity over time

Our approach with adults

Our assessments are neurodiversity-affirming, strengths-based and infused with diagnostic rigour.

Your role is to tell us what it feels like to be you. Our role is to understand how that experience aligns with diagnostic criteria and to support informed next steps, such as referral to appropriate professionals to commence medication and/or therapy if required.

Assessment can offer clarity and direction, particularly for adults who have spent years adapting, masking or pushing through without answers. If that sounds familiar, we encourage you to book an appointment.

Frequently asked questions

Anxiety and autism can look very similar from the outside. Both may involve avoidance, distress in social situations, reluctance to attend school or work, and strong emotional responses. This overlap is particularly common in highly masked autistic children and adults.

The key difference lies in what is driving the anxiety. An anxiety disorder is typically fear-based and responds well to targeted intervention. It does not usually involve a lifelong pattern of social confusion, sensory sensitivities, or a strong need for predictability

For many people with autism, anxiety develops because autistic traits have gone unrecognised. Ongoing effort to cope with social demands, sensory load, and constant adjustment can lead to chronic stress, worry, and avoidance over time. In these cases, anxiety is secondary to autism rather than the primary condition.

This distinction matters. When anxiety is treated without recognising underlying autism, support can be ineffective or even increase exhaustion and overwhelm. Assessment helps identify whether anxiety is a standalone condition or secondary to autism, allowing supports to be matched appropriately and more sustainably.

Autistic burnout and depression are often confused, particularly in adolescents and adults, but they reflect different underlying processes and require different forms of support.

Depression is typically associated with a persistent low mood, feelings of hopelessness or worthlessness, and a loss of interest in activities that were previously meaningful. Treatment may include cognitive behavioural therapy (CBT) or medication.

Autistic burnout is usually the result of prolonged effort (masking) to function in a neurotypical world, which has left you feeling physically and mentally depleted and unable to push through anymore. Strategies commonly recommended for depression, such as increased activity or social engagement, can sometimes worsen autistic burnout. Burnout is more likely to improve with rest, reduced demands, and adjustments that respect sensory needs and energy limits.

No. Information about your childhood can be helpful but it is not essential. We do not require any input from your parents.

During assessment, we place strong emphasis on your own lived experience, reflections and memories, as well as current functioning and patterns over time. Sometimes, we may draw on other sources such as school reports or previous assessments, but these are not required.

Yes, we offer telehealth for adults for both autism and ADHD assessments.
