What Is a Concussion?
Dr. Michael Swartzon, Orthopedics and Sports Medicine Physician at Miami Orthopedics & Sports Medicine Institute, explains a concussion is any change in the neurological status (memory, balance) of a person that occurs after any kind of trauma.
He also says it doesn't have to be a hit to the head, it's anything that results in force to the head. "The brain sits in the skull, there's a space between the bone of the skull and the soft tissue of the brain. In that soft tissue there's a liquid, your cerebral spinal fluid, and it acts as a buffer. You can think of it as a yolk in an egg. If I shake that egg, it could cause a problem even if the egg doesn't crack," he points out.
