If you are trying to make sense of why your family member's behaviour has changed after a brain injury, this piece is for you. It explains what is happening, why it is happening, and what genuinely helpful support looks like in response.
Behaviour after brain injury is not a character flaw
The most important thing to understand is this: when a person with an acquired brain injury becomes aggressive, emotionally volatile, disinhibited or withdrawn, it is not a reflection of who they are. It is a direct consequence of what has happened to their brain.
Different parts of the brain govern different aspects of behaviour, emotion and personality. When those areas are damaged, the effects are specific and predictable:
- Damage to the frontal lobe affects impulse control, emotional regulation and social behaviour. A person may say things without filtering them, become frustrated quickly, or struggle to manage anger in the way they previously could.
- Damage to the temporal lobe can affect memory and the ability to sequence or organise. Confusion about where someone is or what is happening produces anxiety and distress that can look like aggression or refusal.
- Damage to areas involved in executive function affects the ability to plan, shift attention and manage competing demands. Daily life becomes exhausting in ways that are difficult for others to see, and that exhaustion surfaces as behaviour.
The person you love is doing their best with what their brain can currently do. Understanding that does not make it easy. But it changes the frame completely.
"We ask families to hold onto one idea above all others: behaviour is a form of communication. When we understand what is being communicated, we can begin to respond in a way that actually helps."

What can make things harder without meaning to
Some of the responses that feel most natural in the moment can make difficult behaviour more likely to continue. We share this not as criticism but because it makes a real practical difference:
- Trying to reason during a moment of high distress. When someone is in that state, the capacity for logical reasoning is often significantly reduced. The conversation usually escalates things rather than resolving them.
- Giving in to demands made during a distressed episode. Even when it comes from love, this can reinforce the behaviour as an effective way to have a need met.
- Withdrawing visits as a response to a difficult time. For many of our clients, disruption to family contact is itself a significant trigger for distress.
- Expressing high emotion or visible distress. This is understandable and human. But many people with frontal lobe damage are acutely sensitive to the emotional state of the people around them, and that emotion can be contagious in ways that are hard to manage.
None of this means you are doing something wrong. Responding well to brain injury behaviour is a skill that takes time to develop. We work with families at High View to build that understanding together, because your relationship with your family member is one of the most important therapeutic resources they have.
What good support looks like in response
At High View, we use a framework called Positive Behaviour Support (PBS) to understand and respond to behaviour. It is grounded in the principle that behaviour serves a function and that the right response starts with understanding what that function is.
In practice, this means our Clinical Psychologists and Neuropsychologists assess why specific behaviours occur, what triggers them, what needs they represent and what the brain injury is contributing. Those insights are built into each client's support plan and implemented consistently by every member of our team, every hour of the day.
Over time, as underlying needs are understood and met differently, the behaviour itself often reduces. This takes time and it takes consistency. But it works.
Your role as a family member
Your role is not to manage your family member's behaviour. That is our job. Your role is to be a consistent, warm and familiar presence in their life. To visit. To bring the ordinary things, familiar conversation, music they like, news from home, that anchor a person to who they are.
We actively involve families throughout every placement at High View. You will receive regular, honest updates. You are invited to formal reviews. And if you have a question or a concern, we want to hear it directly.
"Families are not observers of rehabilitation. They are part of it. We do our best work when we are working together."
