Brain Injury (also known as Head Injury) is damage caused to living brain tissue. Medically it is referred to as Acquired Brain Injury (ABI), indicating that it is an injury that occurred after birth and is not related to a congenital disorder. An Acquired Brain Injury can be the result of trauma or of medical problems.
Whatever the cause, the resulting damage can impair the individual's abilities both physically and cognitively.
Traumatic Brain Injury (TBI) can occur when damage is caused to the brain by an external mechanical force. TBI's can range from mild to severe - concussion is the most common form of mild TBI.
In New Zealand, the most common causes of TBI are:
Medical problems causing brain injury include aneurysm, brain tumours, subarachnoid haemorrhages and stroke. It also includes brain injury that may be sustained by alcohol and drug abuse.
Everyone is different in the way that they react to a brain injury.
Some may experience a period of unconsciousness lasting minutes, days or in some cases months. Others who suffer a mild concussion may not experience any loss of consciousness.
No one can be sure of the eventual outcome because the brain is so complicated. Recovery depends on a lot of things: for instance the severity of the injury and the 'knock on' effect of bruising inside the brain.
Most people with brain injury keep getting better slowly over many months, even years, but that could mean just getting better than they are now. Some people never recover to become exactly as they were before the accident.
It all depends on which parts of the brain were damaged and how badly.
A brain injury may effect a person physically and socially, as well as impacting cognition, memory, sensory perception, personality and the ability to communicate.
Ongoing problems may include:
A brain injury doesn't only affect the individual, the whole family is affected.
