Brain injuries can have significant effects on behaviour, impacting impulse control and self awareness.
These effects stem from damage to areas of the brain that regulate emotions and impulses and include anger, impulsive behaviour, self-centeredness, impaired awareness and even violence. Changes in a person’s personality and social skills can be confronting and where possible, families should work with the rehabilitation team or specialists to respond consistently to challenging behaviour.
Anger is a common emotional response after a brain injury and can be directly related to impairments caused by the injury.
The ability to view the world from someone else’s point of view is a very complex cognitive skill that occurs in the frontal lobes of the brain. This is a very common area to be affected in a brain injury and other brain disorders which can cause self-centered behaviour.
Lack of self-awareness is a common outcome for people who sustain brain injuries with frontal lobe damage. Their inability to self-monitor and self-correct behaviour can lead to challenging behaviours.
