Study: Youths don't bounce back after 2nd concussion
Children and young adults take longer to recover from a concussion if they've suffered a previous hit to the head within a year or repeated blows at any time, according to a study published on Monday.
Doctors had assumed it was bad for kids to get multiple knocks on the head, but the new study, from Boston Children's Hospital, is the first to confirm the connection and put a time frame on recovery.
The study found that kids and young adults, 11 to 22, who arrived in the emergency room with a repeat concussion — either within a year, or multiple times over a lifetime — took longer to recover than those with a first concussion. A single previous concussion more than a year earlier did not increase the risk for a longer recovery.
Most kids bounce back from concussions within a few weeks, but some take months, and doctors are trying to understand what makes the difference so they can better treat and protect them.
The study, in the journal Pediatrics, suggests that the effects may last longer than thought — something coaches and parents should consider in deciding when kids should return to the athletic field, said Matthew Eisenberg, a study author and physician at Boston Children's.
“This just adds another little weight to the risk side” when weighing benefits and risks, he says.
Patients without a prior concussion took 12 days on average to recover, while those with several previous concussions took 28 days. Recovery from a second concussion within a year took 35 days. About 60 percent had been injured playing sports. It's not entirely clear whether the recovery is longer because the damage lingers unseen for a long time after a blow, or because someone who has had a concussion is more likely to be aware of symptoms.
