Traditional approaches to measuring brain health tend to utilize standardized test batteries that emphasize compartmentalized cognitive domains. However, this approach cannot be readily adapted to different cultures, and we don't believe it captures the true essence of what it means to be human. Rather than conceptualizing cognitive function as test-taking ability, we are focused on ways to passively monitor natural human behavior from which individualized patterns of cognition can be derived. Our approach is based on the belief that individual variability should be valued, not considered noise.
