Neurodivergent children often face unseen challenges during the school day, leaving parents and teachers confused about meltdowns or disruptive behaviour.
Sensory overload affects neurodivergent children at school
Neurodivergence is an umbrella term covering conditions such as Autism Spectrum Disorder, ADHD, Dyslexia, Dyspraxia, and Sensory Processing Disorder.
Each child’s place on the spectrum is highly personal, but many share common experiences within the school environment. Busy classrooms can overwhelm sensory-sensitive children before the first lesson even begins.
Speaking to the Irish Independent, one parent said: “Our teen is having meltdowns. We feel they’re under a lot of stress; we don’t know what to do. We’ve spoken with the school, and they don’t see anything unusual… They just get on with their work without disrupting anyone. We just don’t understand what’s happening.”
In contrast, some parents struggle to manage children who appear constantly disruptive, receiving detentions or weekly suspensions, yet whose underlying struggles are rarely visible.
Nettie Bowie, a child and adolescent psychotherapist, draws on over 14 years supporting neurodivergent children as a Special Needs Assistant (SNA) and 12 years in therapy.
She says many young people describe the school day as a “volcano” - holding stress in until it inevitably erupts at home or in public.
Bowie explained: “Some find it too challenging to hold it in and it explodes wherever they happen to be at the time.”
Sensory overload is often the trigger, with bright lights, humming whiteboards, scraping chairs, crowded corridors, loud playgrounds, and even scratchy clothing overwhelming a child’s nervous system.
Outbursts, verbal or physical, can be misinterpreted as 'bad behaviour,’ when what the child may actually need is a short movement break, quiet corner, or access to a sensory room.
Adult neurodivergent speakers have highlighted the value of movement breaks in school, describing them as crucial “brain recalibration” moments that restore focus and attention.
Schools with SNA support allow teachers to continue instruction while meeting the emotional and sensory needs of these students. A 2025 Department of Education report emphasised that children see SNAs as “an essential part of their ability to engage, participate and thrive in school life.”
Bowie added: “As the adults in these young people’s lives, we need to understand their needs, support their challenges, and help them grow. When you plant lettuce, if it does not grow well, you don't blame the lettuce. You look for the reasons it is not doing well.”
