A new study shows that scores of American children and teens go untreated for concussions each year.

FOX's Jeff Monosso reports:

The study led by doctors at Seattle's Children's Hospital and published in the Journal Pediatrics is a best estimate in the count of concussions in kids younger than 18.

At between one and two million suffered every year during sports or recreational activities, but injuries that researchers say go untreated at least half the time... Meaning that hundreds of thousands of children, according to the study, could be suffering from head injuries that may cause future health and learning problems.

Doctors say if you suspect your child may have had a concussion to contact your doctor.
