About Brain Injury

The long-term effects of a brain injury or disorder are different for each person, and will vary depending on the type of condition, the nature and location of the injury, and various other factors. The impacts of brain injury are also experienced by family and friends, particularly when the injury has resulted in personality or behaviour change.

Brain injuries are often called the ‘hidden disability’ because, although people can experience significant changes in how they think, feel and relate to others, there may be no outward physical signs of injury. As a result, the problems caused by brain injury can be easily ignored or misunderstood by others.

Acquired brain injury (ABI) generally refers to injuries sustained after birth. These include incidents that result an in interruption of blood or oxygen supply to the brain or traumatic external force to the head. Injuries sustained by infants in the womb such as Foetal Alcohol Spectrum Disorder (FASD) are also considered an ABI.

Brain injury also occurs through degenerative brain disorders such as Alzheimer’s disease and  Parkinson’s disease. Brain tumours, infections or brain diseases like Meningitis and Encephalitis can also result in brain injury. Degenerative disorders can have similar impacts to ABI, but their different characteristics may need specialist support.

The long-term effects of a brain injury or disorder are different for each person, and will vary depending on the type of condition, the nature and location of the injury, and other factors. For example, while degenerative disorders typically impact the body’s ability to control movement, other brain injuries may have an impact on cognition, personality and behaviour.
