Activity-Related Symptom Exacerbations After Pediatric Concussion.
Recovery from concussion generally follows a trajectory of gradual improvement, but symptoms can abruptly worsen with exertion. This phenomenon is poorly understood. ⋯ Certain patients appeared susceptible to high and variable symptom reporting. Symptom spikes may not themselves be detrimental to recovery. The present findings support clinical guidelines for adolescents to return to school and activities gradually after concussion.
