Brain injuries due to traffic accidents and falls are expected to be the 7th and 17th major cause of death, respectively, by 2030. Only severe cases of head injury receive close medical investigation, and many are assessed only by rudimentary behavioural observation or the subject’s self-reporting.
This is of concern given that there is currently limited understanding of how the brain is affected by head trauma that occurs in contact sports such as AFL football. Hence there is an urgent need to be able to rapidly and accurately assess the effects of head impact on the brain. One promising approach to quickly and non-invasively examine brain function is through assessment of visual processing.This project will examine visual processing (including a combination of eye-tracking and/or behavioural testing of visual processing speed and attention) in people with and without history of brain injury. Increasingly, neurocognitive testing is being utilised by professional athletes, though refinement of the best measures to accurately identify those with a concussion is needed. In addition, this research can help to uncover the neural and cognitive mechanisms associated with concussion.
