Study finds concussions common in teens
New research from Canada has found that roughly 1 in 5 adolescents has probably suffered a traumatic brain injury--a figure that suggests severe concussion among children and adolescents may be far more common than has been estimated. The new study also hints at a troubling link between a history of traumatic brain injury and poorer grades, underage drinking and use of illicit drugs.
