Three diagrams of human heads, generated from data, show areas of the brain lit up with different colours. A series of lines criss-cross above each head – connecting one area to another.

One in five people with severe brain injuries who are in a vegetative state have some level of consciousness. The two heads on the left — generated from electroencephalogram (EEG) data that measures electrical activity in the brain — show brain networks in two people diagnosed as vegetative. The difference is that the one in the middle can imagine playing tennis when asked to do so. (On the far right, a healthy adult’s brain network while at rest is shown.) Researchers at Western University have been able to elicit “yes” or “no” answers from such patients by asking them to imagine playing tennis. In this way, they hope to determine better prognoses for coma patients in order to provide more appropriate care.

Concussions: A dizzying field of research!

There are 200,000 concussions every year in Canada. If you’re not an elite athlete, your odds of having a concussion are one in 10,000. Professional athletes, on the other hand, will experience three or four by the age of 20. But since there is no way of objectively diagnosing a concussion, and those affected are notoriously reluctant to report their symptoms, the real numbers are likely higher than anyone wants to admit. What stands in the way of acceptance and proper management of concussions?
