Symptom Clusters

symptoms cluster

A young person who has suffered a concussion may tell you about one symptom or may describe a variety of symptoms. After an impact, even one symptom is enough to raise suspicions of concussion. The symptoms may come from any or all of the symptom clusters shown here. Combinations of symptoms will vary based on the individual as well as the injury.

After a trauma, suspect concussion if your patient tells you he or she is having:
