The Cogstate Brief Battery (CBB) is a computer-based cognitive assessment used in clinical trials, healthcare, and academic research to measure neurological cognition.[1][2][3] It was developed by Cogstate Ltd.[4]


The 15-minute assessment consists of four cognitive and neuropsychological tests: Detection, Identification, One Card Learning, and One Back.[5] Each test measures functions in areas such as attention, visual learning, and working memory,[6] and is designed specifically for repeated assessment.


The assessment has been used to measure change in patients with mild cognitive impairment.[7] and dementia,[1][8] sports-related concussions,[9][10] fatigue,[11][12] and alcohol use,[13] and schizophrenia.[6] It can be taken by adults and children, and has minimal practice effects[5][14][6]

In 2019, Cogstate and Eisai announced a partnership to make the test available outside the United States, for use in health care and other markets.[4][15]
