Understanding Anxiety in Neurodivergent Children and Young People

At Insight, we support children, young people and families through assessment, therapy and follow-up care. Anxiety is one of the most common reasons families seek support.

When anxiety is the part other people notice

A child may be struggling to attend school, worrying excessively, becoming overwhelmed by everyday situations, or experiencing emotional outbursts that seem difficult to understand. Sometimes the anxiety is obvious, sometimes it gets lost amidst a storm of big feelings. Sometimes it is identified long before anyone considers whether there might be an underlying neurodevelopmental difference.

For some children, anxiety exists alongside autism or ADHD.

For others, anxiety may develop in response to the challenges of navigating environments that feel overwhelming, unpredictable, or difficult to manage.

Often, it is a combination of both.

Understanding that distinction can be important because it influences the type of support that is likely to be most helpful.

When others see anxiety but you sense something more

We notice recurring themes in our conversations with parents. These are the things we want to write about to help share our understanding.

Parents talk to us about their children struggling with anxiety, but also how the explanations they hear from others don't quite fit with what they have been noticing over time.

A teacher might comment that their child seems shy, nervous, or lacking in confidence. A grandparent may reassure them that all children worry, suggest it is simply part of growing up, or attribute difficulties to the impact of COVID. Others may wonder whether a child needs more encouragement, more exposure to difficult situations, or simply more time to mature.

These perspectives are often offered with good intentions.

At the same time, parents may have been noticing patterns for years.

They may remember sensory sensitivities, friendship difficulties, intense interests, challenges with change, differences in play, or a sense that their child has always experienced the world a little differently.

This can leave families in a difficult position.

The anxiety is real and deserves attention. But when anxiety becomes the only lens through which difficulties are considered, it can sometimes become harder to recognise what else may be contributing to a child's experience.

Some parents tell us they begin to lose confidence in their own observations.

They may wonder whether they are overthinking things, looking for explanations that aren't there, or focusing on the wrong concerns altogether.

Anxiety doesn't always look like worry

When we think about anxiety, we often imagine a child who can tell us they feel worried or nervous.

In reality, anxiety is not always expressed so clearly.

Children's ability to recognise, understand and communicate their internal experiences is still developing. They may know that something feels uncomfortable, overwhelming, or difficult, without having the language to explain exactly why.

Instead, anxiety may be communicated through behaviour.

You might notice:

• irritability or anger

• tears that seem to come out of nowhere

• refusal or avoidance

• shutting down

• physical complaints such as headaches or stomach aches

• becoming overwhelmed by situations that seem manageable to others

In these moments, behaviour is often telling us something that words cannot yet fully express.

Why neurodivergent children may experience anxiety differently

There is no single explanation for anxiety in neurodivergent children and young people. However, there are some experiences that can increase the likelihood of feeling overwhelmed.

Sensory demands

Busy classrooms, noisy environments, certain clothing textures, strong smells, bright lights, or unexpected sensory input can create a level of stress that may not always be obvious to others.

When these experiences occur repeatedly throughout the day, anxiety can begin to build.

Social demands

Social situations often involve navigating unwritten rules, interpreting facial expressions, managing group dynamics and responding flexibly to changing situations.

For some children, this can require significant effort.

Uncertainty and unpredictability

Many neurodivergent children find uncertainty particularly challenging.

Changes to routines, unexpected events, unfamiliar situations, or not knowing what to expect can all contribute to anxiety.

Getting started

Sometimes anxiety is not really about the task itself.

Instead, it is linked to not knowing where to begin.

Executive functioning differences can make planning, organising and initiating tasks difficult. What looks like avoidance may sometimes reflect uncertainty about how to get started.

When anxiety makes sense

If a child repeatedly experiences sensory overload, struggles to predict social situations, finds everyday demands difficult to manage, or spends significant energy trying to cope, anxiety can become an understandable response rather than an isolated problem.

In these situations, anxiety is not necessarily irrational or disproportionate. It may be a very understandable response to a child's lived experience.

But that doesn't mean they simply have to live with it.

Understanding why anxiety is occurring is not about accepting distress as inevitable. It is about identifying the factors that may be contributing to it, so that meaningful support can be put in place.

Sometimes that means adapting environments. Sometimes it means developing new skills and coping strategies. Often, it involves a combination of both.

When families feel blamed

Some families describe feeling pressure to encourage their child to simply "push through" anxiety.

This message can come from many places — wider family members, schools, professionals, and sometimes from society more generally.

The intention is often positive. Most people want children to develop confidence and feel able to cope with challenges.

At the same time, families can sometimes leave these conversations feeling misunderstood, or as though they are somehow making things worse by adapting their approach.

Whilst avoidance can become unhelpful when it prevents children from engaging with important parts of life, pushing through is not always the answer either.

A child who is overwhelmed by sensory demands, exhausted from masking, struggling with uncertainty, or finding everyday expectations difficult to manage may not need more pressure. They may need more understanding.

The goal is not simply to reduce anxiety. It is to understand what is driving it and respond in a way that helps the child feel safer, more capable, and better supported.

What can help?

There is rarely one solution.

Support is rarely about removing every challenge or expecting children to simply push through. More often, it involves finding the right balance between understanding, adaptation and skill development.

Looking beyond what we see

When a child is struggling, it is natural to focus on the part that is most visible.

Perhaps they are refusing school, becoming overwhelmed, withdrawing from activities they previously enjoyed, or reacting strongly to situations that seem manageable to others.

These moments can be difficult for everyone involved.

At the same time, they are often a clue that something is not feeling manageable for the child.

Rather than focusing only on the anxiety itself, it can be helpful to become curious about what might be sitting underneath it.

This shift in perspective often opens up different possibilities for support.

Adapting the environment

Small changes to the environment can sometimes reduce anxiety significantly.

This might include:

• increasing predictability

• preparing for transitions

• reducing unnecessary sensory demands

• adjusting expectations during periods of overwhelm

Supporting emotional understanding

Many children benefit from support to recognise and label their emotions.

Parents and carers can play an important role by helping children make connections between physical sensations, emotions and experiences.

Over time, this can make it easier for children to communicate what they need.

Building skills gradually

Alongside environmental support, children may also benefit from developing strategies for managing uncertainty, coping with challenges and building confidence.

These skills often develop most successfully when children feel understood and supported, rather than pushed beyond what they can currently manage.

A final thought

Anxiety can be the part that gets noticed first.

Recognising it is important. But it is usually only the starting point.

Understanding what may be driving the anxiety — whether that relates to sensory experiences, social demands, uncertainty, executive functioning difficulties, life events, or a combination of factors — is often where meaningful support begins.

When we understand what sits beneath the surface, we are better placed to respond in ways that genuinely help.

Finally, it's also important to remember that support doesn't have to wait for a diagnosis. Holding neurodiversity in mind when thinking about next steps can be helpful in itself.
