A guide for families: brain injury in children
When a child sustains a brain injury, the questions families face are different from those families of adults encounter. Not just “how do we help them recover?” but “how will this affect who they become?”
Brain injury in children is not a smaller version of adult brain injury. The developing brain responds differently to damage, and the effects of an injury in childhood can unfold over years, sometimes becoming more apparent rather than less as the child grows.
This guide aims to explain what makes childhood acquired brain injury distinct, what families can expect over time, and how specialist case management supports children and their families throughout the journey.
Why childhood brain injury is different
When an adult sustains a brain injury, it damages skills and abilities that were already in place. Recovery involves working to regain what was lost. In children, the situation is more complicated.
A child’s brain is still developing. When an injury damages part of the brain, it may affect not only what the child can do now, but also what that part of the brain would have gone on to support as the child matured. Skills that had not yet emerged at the time of the injury, including complex reasoning, emotional regulation, and social understanding, may never develop fully.
This is why children with brain injuries sometimes appear to cope well in the years immediately after an injury, only for difficulties to become more apparent as they get older. Clinicians describe this as “growing into deficit.” As a child reaches new developmental stages and faces greater demands, the consequences of the injury become more visible.
The Child Brain Injury Trust, the UK’s leading charity for childhood acquired brain injury, puts it plainly: challenges can emerge months or even years after an injury, as the child grows and faces new demands. They also note that by the age of 17, 1 in 30 children in the UK will have experienced a childhood acquired brain injury.
What this looks like in practice
The pattern tends to show up at transition points. Starting school brings demands for sustained attention, early reading and maths, and the ability to follow instructions in a group. Moving to secondary school brings a far more complex social world, multiple teachers, abstract reasoning, and the expectation of managing independently. Each transition can reveal difficulties that were not visible before.
Cognitive effects commonly seen in children after a brain injury include slow processing speed, memory problems, difficulty with attention and concentration, and poor organisation. These make school progressively harder, not because the child is not trying, but because the brain is working considerably harder than their peers’ to achieve the same results.
Emotional and behavioural changes are also common, and often the most difficult for families. Irritability, anxiety, impulsivity, and difficulty regulating emotions are all frequent. For parents and carers, it can be hard to know whether a behaviour is a consequence of the injury or part of normal development. Often it is both, and the two are difficult to separate.
Social difficulties tend to intensify through adolescence. Subtle problems reading social cues, keeping up with fast-moving conversation, or managing the emotional demands of close friendships can lead to isolation at an age when belonging matters a great deal.
Fatigue is a major factor that is consistently underestimated. A child with a brain injury may look physically well and manage short periods of activity, but the neurological effort of getting through a school day can be exhausting in a way that others cannot see. A child who cannot concentrate in the afternoon may not be disengaged. They may simply be spent.
The hidden nature of childhood brain injury
Brain injury is sometimes described as a hidden disability, and this is especially true in children. Once the obvious physical effects resolve, the difficulties become invisible to the outside world. A child who sustained an injury at five may, by ten, show few outward signs. But the cognitive and emotional effects are still there, and the gap between that child and their peers may be quietly widening.
This is one reason why long-term follow-up matters. A single assessment at the time of injury does not tell you what a child will need at twelve or fifteen. Case management for paediatric clients is not a short-term intervention. It is an ongoing clinical relationship that evolves with the child.
Our approach to childhood brain injury
At Hawkley Rehab, we have specific expertise in working with children and young people following brain injury.
Louise Hawkley holds an MSc in Neurorehabilitation, with her research focusing on family function following acquired brain injury. She is also conducting doctoral research on psychosocial outcomes in children and adolescents with acquired brain injury. This is not general background knowledge. It is active, current research that directly shapes how we assess and plan for paediatric clients, and it means the evidence base informing our practice is particularly strong in this area.
Ken Hawkley has extensive clinical experience in brain injury rehabilitation for children and adults, including work with young people with cerebral palsy, epilepsy, and sensory impairments alongside traumatic and acquired brain injury.
All cases at Hawkley Rehab are managed jointly by both of us. For paediatric cases, this means two experienced clinicians holding the full picture of a child’s needs from the initial assessment through to ongoing review as the child develops. Our assessments follow the World Health Organisation’s International Classification of Functioning, Disability and Health, a framework that considers not just the injury but how it affects daily life, education, relationships, and participation in family and community life.
Supporting the whole family
The Child Brain Injury Trust has rightly highlighted that siblings are often affected by a child’s brain injury, experiencing their own worries and adjustments that can easily be overlooked. We are alert to this in how we work. Supporting a child after brain injury means understanding the family around them.
We keep families informed at every stage. We liaise with schools, therapists, other professionals, and the legal team as needed. And we adapt the plan as the child grows, because what is needed at eight is not necessarily what will be needed at thirteen.
