The Boston Cognitive Assessment (BoCA) is a self-administered computerized test intended for longitudinal cognitive monitoring. BoCA uses random never repeating tasks to minimize learning effects. BoCA was developed to evaluate the effects of treatment in longitudinal clinical trials and available gratis to individuals and professionals.

BOCA evaluates eight cognitive domains:
1) Memory/Immediate Recall
2) Memory/Delayed Recall
3) Visuospatial Reasoning / Mental rotation
4) Executive function / Clock Test
5) Attention
6) Mental math
7) Language Comprehension/Prefrontal Synthesis
8) Orientation

BOCA has been validated by multiple studies:
• Vyshedskiy, A., et al. "Boston cognitive assessment (BOCA)—a comprehensive self-administered smartphone-and computer-based at-home test for longitudinal tracking of cognitive performance." BMC neurology 22.1 (2022): 1-12.

BOCA results are presented at the end of the test and also emailed. The maximum total score is 30. Higher score indicates better cognitive performance.
