Understanding Hyperactivity: How It Manifests in ADHD, Autism, and Other Neurodevelopmental Conditions

Hyperactivity is just a symptom, not a diagnosis itself. The reason behind it and the way it presents can vary depending on the child's unique neurological makeup. The way it manifests in a child with autism is different from a child with learning disorders. Understanding this can be of immense help to give your child the right kind of support.

In ADHD: The "Always On" Feeling

In ADHD, hyperactivity is prevalent and persistent. It’s there most days, in most situations, and often seems to have no goal. It’s not about what they're doing, but the act of doing it. You might see:

• · Your child can’t sit through a single story or a family meal.

• · They are constantly touching everything, bumping into people, or flitting from one toy to the next.

• · Waiting in a queue is practically impossible.

In Autism Spectrum Disorder (ASD): A Response to the World of sensation

In autism, what looks like hyperactivity often has a different purpose. It can be directly linked to the core traits of autism. For example:

• · Sensory needs: The movement might be a way to seek input (spinning, jumping, pacing) or to avoid overwhelming sensations (running away from a noisy room).

• · Anxiety and change: Activity levels can skyrocket in response to anxiety, a change in routine, or an overwhelming sensory environment.

• · It’s also very common for a child to have both autism and ADHD, making it a mixed picture.

In Intellectual Disability: Developmentally Speaking

For a child with an intellectual disability or global developmental delay, it’s crucial to look at their "mental age," not just their chronological age.

• · A 10-year-old with a developmental age of 4 will naturally behave like a very active young child. The question isn't whether they're active, but if their activity level is excessive even for a child of their developmental stage.

In Learning Disorders: The Frustration Factor

·A child with a specific learning disorder, like dyslexia, may not have true hyperactivity. However, when faced with a frustrating task (like reading), they might become restless, fidgety, or try to leave the situation. This is often an avoidance behavior driven by anxiety and difficulty, not the same "driven-by-a-motor" feeling seen in ADHD

Other Conditions: The Mimics

Sometimes, other conditions can look like hyperactivity. For instance, a child with a tic disorder might seem restless because of frequent, sudden movements. Sleep disorders, anxiety, or even certain medications can also cause increased activity or agitation that can be mistaken for hyperactivity.

This is exactly why getting a professional opinion is so important. A developmental paediatrician or child psychologist can help untangle these different threads.

So, how do you know when to seek help? It’s time to talk to your pediatrician or a specialist if:

• · Your child’s activity level is significantly higher than that of their friends or classmates.

• · Teachers consistently report that your child’s movement is disrupting their learning or the classroom.

• · Their behaviour is affecting their ability to make friends or is putting their safety at risk.
