Sport can be a source of concussions. especially contact sports where the head and body are subjected to sudden forces of acceleration for which they are unprepared. This kind of injury can affect various systems (brain, cervical spine, equilibrium organ in the inner ear) simultaneously. Through our interdisciplinary collaboration, our extensive medical support network through the Swiss Olympic Medical Center and daily work in the field of elite sport, we also treat patients with complex concussions and offer advice to external institutions.
