Concussions are much more common than most people know. Unless you can spot the signs and symptoms, a concussion in your child could go undiagnosed.
Concussion comes from the Latin word concussus, which means to shake violently. The tremendous force of a blow to the head can create contusions (bruises) and a loss of nerve connections in the brain. These nerve connections help us perform basic functions like concentration, reaction time, short and long term memory, and visual cognition, as well as basic things like sleep, speech, and emotions.
Though we often think of concussions occurring from fast, hard-hitting sports like football and ice hockey, they can occur from any collision (including bicycle, ATV, and skateboard accidents) or contact activity (such as soccer, gymnastics, or even dancing).
