A rapid and reliable cognitive screening assessment across indications and phases of development.
The Cogstate Brief Battery™ has been used extensively as a rapid and reliable screening assessment in a range of clinical indications, including Alzheimer’s Disease, depression, schizophrenia, AIDS, dementia complex and as a measure of cognitive decline following a mild traumatic brain injury or suspected concussive episode. The Cogstate Brief Battery has also been used widely in the context of measuring cognitive dysfunction relative to healthy groups in both pediatric and adult populations.
The Cogstate Brief Battery provides a measure of four core cognitive domains: processing speed, attention, visual learning and working memory. 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 have been utilized previously in clinical trials and maintain excellent reliability across repeated testing and cross-sectional research designs. This battery maintains excellent psychometric properties in relation to test-retest reliability. The criterion and construct validity of each test for cognitive impairment as well as the sensitivity of these tests to change in cognition has been demonstrated in the scientific literature, and each test has also been shown to be valid for use in different cultures and language groups.
