The C-Score is a summary of your current cognitive function.
It is similar to an average of test scores, though the calculations are a little more complicated (see How is the C-Score Calculated?). It gives you a snapshot of how well your brain is functioning at any given time, across all three of the mental domains challenged by the tests. You can think of it as related to IQ, but not quite the same: read more about the key differences between the C-Score and IQ.
The C-Score is designed to assess many key mental functions without taking very long to complete. It is also designed to be sensitive to changes, so that if you are feeling pretty smart today, the C-Score can verify it. Hundreds of scientific studies have used the Cambridge Brain Sciences tests and demonstrated that cognitive performance changes in response to various interventions. We will know more about how the C-Score itself changes due to lifestyle as we collect more data—so keep completing your lifestyle entries when you visit.
Because the C-Score is an overall score, it does not tell you how well any specific brain network is functioning—that's what cognitive domain scores are for. If all areas of your cognition are functioning highly, then your C-Score will be high. However, if you are weak in one domain, your C-Score will be lower. For more detail about which domains are performing well, view your reasoning, short-term memory, and verbal ability scores.
