People develop behaviour skills over many years as they grow and mature into adulthood. A brain injury can affect parts of the brain involved with emotions, impulse control, self-awareness and ability to monitor and change behaviour. Injury often means a person needs to relearn behaviour skills, which in some cases may be extremely difficult.
Behaviour that is considered acceptable is set by thousands of unwritten rules. Some examples include:
- how close to stand to other people
- when it is okay to interrupt another person
- when and how to show emotions
- how to interpret and respond to non-verbal communication
- when and what parts of a person’s body may be seen naked.
Behaviour that breaks these ‘rules’ can lead to social exclusion, restricted access to community services, family breakdown and even may even have criminal consequences.
