Power Down to Speed Concussion Recovery: Study
Research supports several days' mental rest, including no screen time

MONDAY, Jan. 6, 2014 (HealthDay News) -- Young people who suffer a concussion often want to return to school and begin using electronics right away, but resuming everyday life too quickly might delay recovery, researchers say.
Kids who give their brains a few days' rest and gradually return to normal mental activity heal faster than those who rush back to their books, computers and TVs, a new study suggests.
"After a concussion, we recommend rest because kids tend to do too much," said the study's lead author, Dr. Naomi Brown, a physician in the division of sports medicine at the Children's Hospital of Philadelphia.
Senior study author Dr. William Meehan, director of the Sports Concussion Clinic at Boston Children's Hospital, said that although the findings suggest vigorous mental exertion is detrimental to recovery, more moderate levels of mental exertion do not seem to prolong recovery substantially.
"We recommend a period of near full mental rest after injury -- approximately three to five days -- followed by a gradual return to full levels of mental activity," Meehan said.
Brown said parents might overreact and want their children to refrain from any activity that requires concentration. But the study of more than 300 concussion patients, which was published online Jan. 6 in the journal Pediatrics, showed that only those who reported the most mental activity took the longest time to fully recover -- an average of 100 days.
For the others, a complete retreat from mental stimulation was no more effective than partial rest. "If you shut down completely, meaning you don't go to school or do any reading or screen time, or if you do a little bit less than normal, you recover in the same time period -- an average of 20 to 50 days," Brown said.
After concussions, young people can resume normal mental activity a little at a time. Brown suggested working only to the point where symptoms such as headaches, blurred vision or dizziness begin. That's when the brain is being overstimulated.
"We are not recommending complete abstinence from school, especially after the first week," she said. "If you go to school for a couple of hours and you are doing OK, then the next day you can go for a little bit more and slowly test it out."
