The Brain Injury Clinical Research Center at Kennedy Krieger Institute is recruiting youth ages 10 to 17 who have had a recent concussion or have never had a concussion. The research study explores brain recovery after concussion, in relation to motor performance and brain connectivity. It involves three visits over the course of one year and is located in Baltimore. There is no cost to participate. Participants will receive a $50 gift card for each study visit, a $10 gift card for each MRI completed at study visits, and an additional $5 in gift cards for the completion of monthly survey responses.
