Why Rest Following Concussion is Critical
"...When a mild concussion occurred each day for a month, inflammation and damage to the brain’s white matter resulted. “This damage became progressively worse for two months and remained apparent one year after the last impact,” Burns says. “The findings mirror what has been observed about such damage in humans years after a brain injury, especially among athletes,” Burns says. “Studies have shown that almost all people with single concussions spontaneously recover, but athletes who play contact sports are much more susceptible to lasting brain damage.
