Behaviour Changes​ After Brain Injury

 

Understanding Behavioural Needs

Behaviour that challenges is a common and often complex response following childhood brain injury that may impact upon learning, relationships, participation in daily activities and emotional well-being. Research indicates that up to 50% of children with brain injuries may develop behaviour that challenges, which may appear shortly after the injury or emerge years later as greater demands are placed on weaker cognitive skills.

​

When a child experiences a brain injury, changes may occur in areas of the brain responsible for attention, emotional and behavioural regulation, impulse control, and social functioning. As a result, children may find it harder to communicate their needs, cope with frustration, manage change and keep up with everyday expectations. Fatigue and cognitive overload may also compound these difficulties, leading to behaviours that can feel confusing or distressing for families, schools and peers. These behavioural changes after childhood brain injury can vary widely depending on age, type of injury and the demands placed on the child.

​

Importantly, behaviour that challenges is an understandable response to altered brain functioning and environmental pressures. It is not a reflection of parenting, a child’s character or ‘naughtiness’, but often a signal that the child or young person needs adjustment, understanding and tailored support to manage everyday demands. Effective responses focus on assessment and practical strategies, such as reducing triggers, pacing cognitive and emotional demands, supporting communication, strengthening emotional regulation skills and aligning expectations across home, school and therapy environments.

​

Case managers play a crucial role in coordinating assessments, support and intervention to help ensure that plans are consistent, proactive and responsive to the child’s evolving needs.

How Behaviour May Present in Daily Life

 

Behaviour that challenges can present in different ways and may include:

​

Impulsivity or risk-taking:

Children may act without thinking, finding it difficult to consider the consequences.

Examples: interrupting others, grabbing objects suddenly or leaving a classroom without permission.

​

Aggression or oppositional behaviour:

Often linked to frustration, confusion, fatigue or difficulty communicating needs.

Examples: shouting, hitting, kicking, throwing objects or refusing to follow instructions.

​

Irritability or low frustration tolerance:

Children may become upset more easily than before the injury and react strongly to small challenges.

Examples: becoming distressed by changes, noise or unexpected events.

​

Emotional outbursts or ‘meltdowns‘:

Sudden episodes of intense emotions that may seem out of proportion to the situation.

Examples: crying, shouting, panic or anger.

​​

Withdrawal or refusal:

Some children may become quieter, more passive or disengaged when overwhelmed.

Examples: avoiding social situations, refusing to join activities or spending more time alone.

​

Disinhibition:

Children may lose some of their “social filters”, saying or doing things that appear unexpected or inappropriate.

Examples: making unfiltered comments or crossing personal boundaries without realising.

​

Behaviour that challenges may look different across settings, such as home, school or therapy. This is because each environment has different expectations, levels of structure, noise, familiarity and social demands. Understanding these differences helps adults recognise that children are responding to their environment, fatigue and emotional demands – rather than deliberately misbehaving. 

​

 

Why Behaviour Changes Occur After Brain Injury

 

Behavioural changes after childhood brain injury are influenced by a combination of neurological, psychological and environmental factors. 

​

Neurological & Cognitive Changes

Following a brain injury, some children experience changes in thinking skills that help them plan, organise and manage daily activities. These ‘executive functioning’ skills include: 

​

• Inhibition/self-control: stopping and thinking before acting.

• Planning and organisation: working out what needs to be done and how.

• Flexibility: coping with change and moving between tasks.

• Working memory: holding information in mind long enough to use it.

 

Children may also experience difficulties with attention, memory or processing speed. This may make it harder to:

​

• Remember instructions

• Stay focused on tasks

• Switch attention between activities 

• Keep up with information as quickly as others

​

When these skills are affected, schoolwork, everyday routines and social situations can feel much more demanding. Children may lose track of what they were doing, need repeated promoting, or appear distracted or ‘drift off’ during tasks or conversations. This may lead to task avoidance, refusal or withdrawal – due to changes in their cognitive capacity.​

​

Emotional & Social Regulation

Brain injury can affect emotional regulation – the ability to manage and recover from strong feelings. Children may become overwhelmed more quickly, experience emotions more intensely and take longer to calm down. This may look like:

​

• Sudden emotional outbursts or ‘meltdowns’

• Strong reactions to small problems

• Becoming tearful, angry or anxious very quickly

• Difficulty calming down without adult support

• Shutting down or withdrawing when overwhelmed

​

Changes in thinking skills can also affect social understanding. Children may interrupt, misread social cues, react ‘out of proportion’ or struggle to repair friendships after disagreements. These difficulties can lead to misunderstandings, impact confidence and self-esteem, and reduce willingness to join in social activities.

 

Recognising that these behaviours reflect changes in brain functioning – rather than deliberate behaviour – supports more compassionate and effective responses.

Communication Difficulties 

Communication difficulties following brain injury may affect a child’s ability to understand language, process information or express themselves. Children may:

​

• Struggle to find the right words 

• Forget what was said 

• Find it hard to keep up with conversations

• Appear to misunderstand instructions

• Withdraw or avoid situations where communication feels difficult

​

When this happens, children may feel misunderstood or left out, which can increase distress or frustration. Behaviour that challenges may occur when they are unable to communicate their needs effectively. Younger children may not yet have the language or coping skills to explain how they feel and may instead show distress through behaviour or physical reactions, such as crying, becoming overwhelmed.

Fatigue, Physical Symptoms & Frustration

After a brain injury, children often become tired more quickly, especially after busy school days, social activities or therapy sessions. This fatigue can reduce their ability to cope with noise, busy environments or unexpected changes, which can make it harder to think clearly, manage emotions and regulate behaviours. 

​

Headaches or other physical discomfort can also reduce stamina and make it harder to join in activities, concentrate in class or participate socially. In addition, frustration is common when tasks that were once easy now feel much more difficult (e.g. completing homework, following instructions or keeping up with peers). This can lead to emotional distress, feelings of loss or anger, which may be expressed through behaviour that challenges. 

 

Adjustment, Expectations & Environment

Some children may not fully recognise how their abilities have changed, which can be  confusing or distressing. Changes in friendships, independence or participation can also affect confidence and emotional well-being. These difficulties can particularly affect behaviour in school after brain injury, where demands on attention, stamina and social functioning are high.

​

Behaviour that challenges may also occur when the expectations placed on a child exceed what they are currently able to manage. This may relate to thinking, remembering, problem-solving, attention, social or emotional coping. Children may also feel overwhelmed when environments are busy. This ‘mismatch’ between what is being asked and what they can manage may lead to feelings of distress, withdrawal or behaviour that challenges. 

 

Trauma, Anxiety & Emotional Response

Experiencing a brain injury can be traumatic and some children may develop anxiety or post-traumatic stress symptoms. These experiences can affect both behaviour and emotional well-being. When a child feels unsafe or overwhelmed, they may react emotionally or through behaviour, particularly in situations that remind them of the injury or feel unpredictable or demanding. 

​

Each child’s temperament – whether naturally adaptable, sensitive or cautious – may also influence how they respond to new challenges. Understanding these emotional factors helps adults respond with empathy, reassurance and appropriate support. 

​

​

The Impact on Children & Their Families

 

Behaviour that challenges can place strain on family routines and relationships, creating uncertainty for parents and siblings. Siblings may feel confused or worried about the changes they see, and daily life may feel disrupted. Parents, carers and family members may experience a range of emotions, including worry, frustration, sadness or guilt. Children and young people themselves may feel misunderstood, anxious or overwhelmed as they face new challenges.

When planning support, it is important to consider the impact of behaviour on:

​

• Family routines and relationships

• School participation and learning

• Friendships and social inclusion

• The emotional well-being of both the child and their family

 

Support plans should aim to address each of these areas to promote stability, confidence and positive outcomes.

​

What To Look For

Case managers play a vital role in identifying patterns, triggers and the impact of behaviour that challenges. Careful observation helps build a clear understanding of why behaviours are occurring and what support is needed. 

It is important to consider whether behaviour occurs:  

​

• At times of fatigue or following busy activities

• During transitions or changes in routines

• Following increased cognitive demands

• In response to sensory overload (e.g. noise, visual stimulation or busy environments)

 

It is also important to note any changes in behaviour since the injury and how parents and carers, schools or other services are responding (for example, exclusions or reduced timetables). The confidence and capacity of parents and carers to manage behaviours should also be considered, along with any gaps in current strategies or support.

​

​

Supporting Behavioural Needs Following Brain Injury

​

Assessment Pathways

A whole-child, multidisciplinary assessment is essential when supporting children and young people with behaviours that challenge after brain injury. This approach brings together relevant professionals – including neuropsychologists, educational psychologists, educators, therapists and medical specialists – to build a full understanding of the child’s strengths and needs. Psychological assessment may include:

​

• Neuropsychological testing to understand executive functioning, attention, memory and processing.

• Functional behavioural assessment to explore triggers and patterns of behaviour.

• School observations to understand how the child manages daily demands.

• Interviews with parents/carers to gather family perspectives.

• Review of home, school and therapy environments to identify supports and pressures.

 

Case managers can coordinate this process, ensuring that relevant information is gathered across settings and used to develop a clear, cohesive and practical support plan.

​

​

Positive Support Strategies

The following evidence-based strategies may be considered and integrated into support plans, as appropriate:

​

• Positive Behaviour Support (PBS) informed by neuropsychology: understanding the reasons behind behaviour, building skills and reinforcing helpful behaviours.

• Clear expectations, routines and structure: predictable rules, preparation for transitions and consistent responses across settings can help children to understand what is expected of them and reduce anxiety.

• Visual and communication aids: visual schedules, checklists, prompts or social stories to support understanding, information processing and memory.

• Emotional regulation and wellbeing support: helping children recognise feelings, teaching simple coping strategies (e.g. breathing techniques, calm breaks), providing reassurance and supporting adjustment to changes following injury.

• Executive function scaffolding: providing step-by-step guidance, prompts, chunking tasks and reminders and to support planning, organisation, task completion and memory.

• Environmental adjustments and fatigue management: reducing sensory overload (e.g. noise, visual clutter), providing quieter spaces, planning rest breaks and adjusting workload or social demands.

• Processing-time support: slowing the pace, allowing extra time for responses and breaking instructions into smaller, manageable steps.

• Social support: structured peer activities, supported social participation, and opportunities to practise social skills to maintain friendships and confidence.

• Collaborative goal-setting: involving the child, family, school and professionals in agreeing achievable goals, reviewing progress and celebrating progress.

• Parent/Carer and staff support: providing guidance and training to support confidence and consistency across home, school and therapy settings. 

• Trauma-informed, compassionate approaches: acknowledging emotional responses to injury and supporting safety, reassurance and trust.

When to Refer 

With the right support, children and their families can feel more confident in navigating challenges and making meaningful progress. Knowing when to seek specialist support can make a significant difference. Case managers should consider a referral for specialist support when:

​

• Behaviour that challenges is placing the child or others at risk of harm.

• Behaviours are severe, persistent or escalating.

• The reasons for the behaviour are unclear.

• There are concerns about underlying neurological or psychological factors.

• The child is experiencing ongoing difficulties at school, with friendships or within family life.

• There are concerns about the child’s emotional well-being or mental health.

• Families are experiencing parental burnout or feel unsure about how to manage behaviours.

• There are post-injury changes that cannot be explained by the child’s previous Special Educational Needs (SEN) history.
