Concussion Alters Cerebral Blood Flow in Young Athletes
November 30, 2011 - A single sports-related
concussion in an adolescent leads to a
significant reduction in cerebral blood flow
(CBF) that may persist for more than 1 month
after the injury, new research suggests.
.
"This study adds to the expanding evidence
that concussion is a serious injury that takes
considerable time to recover from for many
kids," Todd A. Maugans, MD, from the Division
of Pediatric Neurosurgery, Cincinnati
Children's Hospital Medical Center in Ohio,
told Medscape Medical News.
.
Among 12 concussed 11- to 15-year-olds in this
study, two thirds still had CBF alterations at
2 weeks, and one quarter at 1 month. Furthermore,
Dr. Maugans said, "clinical recovery by testing
and symptom resolution did not predict physiologic
recovery in this small group of concussed kids."
.
However, the researchers did not find measurable
evidence of structural damage. "At least in
younger children, sports concussion does not seem
to cause serious structural or metabolic injuries,
which is different than adults," Dr. Maugans said,
"so parents do not need to worry that a single
sports concussion has likely done any serious
permanent damage."
.
The study was published online November 30 in
Pediatrics and will appear in
the January 2012 print issue of the journal.
