Research and Statistics

Acquired Brain Injury (ABI) refers to any damage to the brain that occurs after birth.

The main causes of ABI are; accident or trauma, stroke, brain infection, disease or tumour and drugs and alcohol. An ABI can affect cognitive, physical, emotional and independent functioning.

In Western Australia a conservative estimate shows that 2.3% of the population or 60,034 individuals have an Acquired Brain Injury (ABI). This is based on Western Australia’s current population of 2,600,000 (ABS 2009, ABS 2016).

Points to note about statistics and ABI:

  • Not all people with an ABI or Traumatic Brain Injury (TBI) are hospitalised and so are not recorded in hospital data;  
  • If admitted to hospital, an ABI or TBI may not be recorded at the initial intake or as principal diagnosis; 
  • Surveys of disability often only record the main disabling condition.
