Cogstate Brain Injury Battery

Assess cognitive function in subjects with concussion and Traumatic Brain Injury (TBI).

Cogstate’s computerized battery of rapid, reliable, simple and sensitive tests measure the cognitive domains affected by concussion and TBI, namely processing speed, attention, visual learning, working memory, visual motor function and executive function.

The construct validity of each test for cognitive impairment in concussion and TBI as well as the sensitivity of these tests to change in cognition has been demonstrated in the scientific literature. The tests have also been shown to be valid for use in professional athletes, different cultures and different language groups, with comparative/normative data available for both clinical samples and healthy controls. Study teams wishing to measure all or a subset of these domains can choose the tests that best suit their specific research questions. Each of the tests maintains excellent reliability across repeated testing and cross-sectional research designs.
