Can a concussion change your gut microbiota?
Athletes who participate in contact sports are at risk of suffering from concussions, which can result in chronic headaches, nausea, anxiety and depression. Head injury also induces intestinal changes, including to microbes found in the gut; and the brain, in turn, can react to signals from the intestinal microbiome. This interaction is called the “brain-gut” axis. The results from this study will help us to identify temporal sequelae and biomarkers of head injury and will lead us to new treatments to prevent the consequences of concussions.
