What Is Sensory Processing Disorder?

Sensory processing disorder (SPD) is a condition that affects how a child’s brain receives and responds to sensory information from the world around them. While most people process sights, sounds, touch, and movement automatically, children with SPD tend to feel overwhelmed, confused, or uncomfortable when presented with these sensations.

Understanding the Senses

Sensory information does not only come from the five familiar senses of sight, hearing, smell, taste, and touch. The body also relies on several lesser-known internal senses that help children understand movement, body position, and physical needs. Also called “hidden senses,” these are:

The Volume Control Analogy

The brain is constantly receiving and processing sensory information from many sources at once. For most people, this happens in the background without much effort.

You can think of sensory processing like a volume control. For many children with sensory processing disorder, the sensory “volume” may feel turned up much higher than it does for others. When this happens, everyday environments such as classrooms, playgrounds, or busy shops can quickly feel overwhelming.

Sensory Processing Disorder Vs Autism, ADHD, And Anxiety

Sensory challenges are often discussed alongside conditions such as autism, ADHD, and anxiety. Many children with these conditions experience sensory differences as part of their overall development.

However, sensory processing disorder is not limited to these diagnoses. Some children experience sensory processing difficulties without meeting the criteria for another condition. In these cases, sensory differences may be the main challenge affecting behaviour, attention, or comfort in everyday environments.

While there can be overlap, these conditions focus on different areas.

A paediatrician or occupational therapist can help families understand whether sensory challenges are part of a broader condition or occurring on their own.

Types And Signs Of Sensory Processing Disorder In Children

Sensory processing disorder can appear in different ways depending on how the nervous system responds to sensory information. Some children are very sensitive to sensory input, while others may seek out strong sensory experiences.

Professionals generally group sensory processing differences into three main patterns.

Sensory Modulation Disorder

Sensory modulation refers to how strongly a child reacts to sensory input. Some children may be very sensitive to sounds, textures, lights, or movement. Others may seem less aware of sensory input, or may actively seek strong sensations.

Children may show patterns such as:

  • covering their ears in noisy environments
  • avoiding certain clothing or food textures
  • constantly jumping, spinning, or crashing into objects
  • needing movement to stay focused

These reactions are often the child’s way of trying to manage sensory input.

Some children experience sensory challenges that affect movement and coordination. This pattern is sometimes called sensory-based motor disorder.

Children may have difficulty with body awareness, balance, or planning movements. Parents might notice things like:

  • clumsiness or bumping into objects
  • poor balance or posture
  • difficulty learning new physical skills
  • challenges with handwriting or fine motor tasks

Activities such as playground games, sports, or craft activities may feel especially difficult.

Sensory discrimination refers to how clearly the brain interprets sensory information. Children with sensory discrimination difficulties may struggle to tell the difference between similar sensations.

For example, a child might have trouble:

  • judging how tightly to hold objects
  • identifying where their body is in space
  • recognising differences between similar sounds
  • interpreting touch or temperature accurately

These challenges can affect coordination and everyday tasks.

Sensory Meltdown Vs Behavioural Tantrum

Parents sometimes worry that their child’s reaction to sensory overload is a behaviour problem. In many cases, what looks like a tantrum may actually be a sensory meltdown.

A sensory meltdown happens when a child’s nervous system becomes overwhelmed. The table below shows some common differences.

Feature Sensory Meltdown Behavioural Tantrum
Trigger Sensory overload (noise, crowds, textures) Frustration or not getting something desired
Behaviour Child appears overwhelmed and unable to control their reaction Behaviour often aimed at getting something
Duration Continues until the child’s nervous system settles Often stops if the child gets what they want
Recovery Child may feel tired, upset, or withdrawn afterwards Child usually returns to normal quickly

Understanding this difference can help parents respond with support rather than discipline.

When To Seek Support For Sensory Processing Disorder

Many families begin to wonder about sensory processing when everyday routines start to feel stressful for their child. You may consider speaking with a paediatrician or occupational therapist if:

Seeking advice does not mean something is wrong with your child. Often, it simply helps families better understand their child’s sensory needs.

Sensory Processing Disorder Treatment And Management

Support for sensory processing disorder focuses on helping children manage sensory input and feel more comfortable in everyday situations. Strategies are usually tailored to each child and adjusted as their needs change. Common approaches include:

Sensory Integration Therapy

Sensory integration therapy uses structured activities to help the brain respond to sensory input more effectively. Through guided play involving movement, balance, and touch, children can gradually learn to process sensory information in a more organised way.

Occupational Therapy

Occupational therapists assess how sensory processing affects everyday activities such as play, learning, and self-care. They develop practical strategies that help children feel more comfortable and confident at home, at school, and in the community.

Sensory Diets

A sensory diet is a personalised set of activities that provides the type of sensory input a child’s body needs throughout the day. These activities can help support focus, regulate energy levels, and make daily routines easier to manage.

Environmental Adjustments

Environmental adjustments involve small changes to a child’s surroundings that help reduce sensory overload. This may include adjusting lighting, reducing noise, changing seating arrangements, or introducing calming routines.

How Occupational Therapy Helps Children With Sensory Processing Disorder

Occupational therapists help children develop the skills they need to take part in everyday activities. An occupational therapy assessment may look at how sensory processing affects:

Therapy may include activities that improve body awareness, build regulation skills, and help children feel more comfortable in different environments.

Importantly, strategies are designed for real-life situations, including home, school, and community settings.

Supporting Your Child With Sensory Processing Disorder

Learning that your child may have sensory processing differences can feel overwhelming at first. Many families find reassurance in understanding that sensory challenges are common and that support strategies can make daily life easier.

With the right guidance, children can learn ways to manage sensory input, feel more comfortable in different environments, and build confidence in their abilities. If you have concerns about sensory processing, speaking with an occupational therapist can be a helpful first step in understanding what your child may need.
