CBT and Neurodiversity: Understanding the Difference Between Anxiety and ADHD or Autism

Many parents I work with share that they feel unsure about what is really going on for their child.

Is it anxiety?

Is it ADHD?

Is it autism?

Or could it be a combination of both?

It can feel difficult to know whether a child’s struggles are related to their mental health, their neurodevelopmental differences, or the environment around them. Often, children who are neurodivergent experience the world in a way that can feel overwhelming, unpredictable or exhausting. Things that may appear simple to others, such as busy classrooms, social expectations or changes in routine, can feel particularly challenging.

Over time, this can lead to anxiety, low confidence, emotional overwhelm or avoidance behaviours. Many parents find themselves wondering whether their child needs mental health support, environmental adjustments, or both.

Neurodiversity and mental health often overlap

Children with ADHD or autism are more likely to experience anxiety or low mood. This is not because something is “wrong” with them, but because the world is not always designed with their needs in mind.

For example, a child with ADHD may feel anxious after repeated experiences of being told off or feeling unable to meet expectations. An autistic child may feel overwhelmed by sensory environments or social uncertainty. Some children work incredibly hard to cope during the school day (masking) and then feel exhausted or emotionally overwhelmed at home (their safe space). Like a bottle of fizzy pop being shaken and then exploding from too much pressure!

When children feel misunderstood, or as though they are constantly trying to meet expectations that feel too difficult, this can begin to affect their confidence and emotional wellbeing.

When is CBT helpful?

Cognitive Behavioural Therapy (CBT) can be very helpful for children experiencing anxiety alongside ADHD or autism. CBT helps children to understand their worries, recognise patterns in their thoughts and feelings, and develop practical tools to feel more confident managing challenges.

However, CBT should always be adapted to suit the individual child. Neurodivergent children may benefit from a slower pace, more visual supports, or strategies broken down into smaller steps. Sessions may focus on building confidence gradually, understanding emotional experiences, and developing coping tools in a way that feels achievable and fun!

Supporting the child as a whole

What does this child need in order to feel safe, understood and able to cope?

In my work, I have supported many families facing these uncertainties. Often we work together to understand what may be causing distress, what environments may need adapting, and what tools may help the child feel more confident.

Sometimes small changes to the environment can make a big difference. Other times, helping a child develop coping strategies allows them to feel more in control. Often, a combination of both approaches is most helpful.

Working collaboratively with families

Every child is different, and there is no one single approach that works for everyone. By working together, we can focus on understanding the child’s needs, strengths and experiences, and develop support that feels manageable and realistic.

The goal is not to change who a child is, but to help them feel more comfortable, capable and understood in their world.

If you are unsure whether your child’s difficulties are related to anxiety, ADHD, autism, or a combination of factors, you are not alone. Many families experience this uncertainty, and with the right support, it is possible to find ways forward that help children feel calmer, more confident and better supported.
