Predicting clinical recovery of children with concussion is challenging. While concussion symptoms typically resolve within one to three weeks, up to one-third of children develop persistent post-concussive symptoms (PPCS), including headache, nausea, dizziness, blurred vision and sensitivity to light and/or sound.
