Accurate up to date statistical information is difficult to obtain.

It is estimated that there are 6000 new cases in Australia annually admitted to hospital with traumatic brain injury (including stroke).

Many require hospitalisation, but do not have significant residual impairment.

However the Australian Institute of Health and Welfare data indicates that approximately 15% need rehabilitation and ongoing care.

For more statistical information about the incidence and prevalence of acquired brain injury refer to Hillier, Sharp and Metzer 1997. Epidemiology of traumatic brain injury in South Australia. Brain Injury 11 : 649-59. Fortune N and Wen X 1999. The Definition, incidence and prevalence of Acquired Brain Injury in Australia, Australian Institute of Health and Welfare Canberra.

Estimates of incidence range from 100 - 377 per 100,000 population p.a.

In 1993, 110200 people reported that assistance or supervision was required for personal care and activities of daily living (due to ABI).
