Pediatric concussion signs
A new meta-analysis identified a specific set of signs and symptoms that better indicate concussion in children and adolescents, moving beyond the idea that loss of consciousness is the key marker. The review supplies a symptom-based framework designed to help bystanders, parents and clinicians recognise concussion and decide on early triage steps within the first 24 hours. (buffalonews.com)
A child can have a concussion without blacking out, and a new JAMA review says headache, dizziness, mental fog and sensory symptoms are stronger clues in the first exam. (jamanetwork.com) The review, published online April 6, 2026, pooled 23 observational studies on children and adolescents after a plausible head injury. It was led by Sonal Shah of Boston Children’s Hospital, with Haley Chizuk of the University at Buffalo among the co-authors. (jamanetwork.com; buffalo.edu) The findings that most raised the odds of concussion were mental fog, sensitivity to noise, sensitivity to light and nausea. Oculomotor problems on exam — including abnormal near-point convergence, smooth pursuits and saccades — also pointed toward concussion, though they appeared less often. (jamanetwork.com) The one finding that most lowered the odds was no headache. The authors said no single sign could confirm or rule out concussion on its own. (pubmed.ncbi.nlm.nih.gov; em.umaryland.edu) A concussion is a mild traumatic brain injury caused by a bump, blow or jolt to the head, or by a hit to the body that snaps the head back and forth. The American Academy of Pediatrics says that motion can trigger chemical changes in the brain and stretch brain cells. (aap.org) That matters in children because concussion often shows up as a cluster of symptoms instead of one dramatic event. The University at Buffalo summary of the study said the review was designed to sort out which commonly tracked symptoms are actually most useful for early recognition. (buffalo.edu) The paper also highlighted drowsiness, fatigue and trouble remembering as useful features in the first evaluation. The authors said any of those symptoms should prompt removal from play and assessment by a trained medical professional. (buffalo.edu) That fits with existing federal guidance for the first day or two after a head injury. The Centers for Disease Control and Prevention checklist tells clinicians to watch for early signs such as appearing dazed, confusion, slow answers, repeated questions and recent-memory problems, alongside symptoms like headache, dizziness, nausea, balance trouble, light sensitivity, noise sensitivity and drowsiness. (cdc.gov) The review does not replace a full medical exam, and it does not say every child with one symptom has a concussion. It gives parents, coaches, school staff and clinicians a more specific first-24-hours checklist than loss of consciousness alone. (pubmed.ncbi.nlm.nih.gov; buffalo.edu)
