What are the symptoms of a concussion?

Dr. Jeanne Morrison, PhD
Family Practitioner

The symptoms of a concussion may not appear immediately following the head injury, but in other cases, they do. Some people may lose consciousness when they suffer a concussion, but a majority of people do not. More commonly, people with concussions suffer general confusion, headaches, nausea, dizziness and a ringing in the ears.

Signs of a concussion include:

  • Confusion, which may last from moments to several minutes
  • Headache
  • Repeated questioning about what happened
  • Temporary memory loss, especially for periods immediately before and after the injury
  • Brief loss of consciousness
  • Nausea and vomiting
  • Speech problems (person is unable to answer questions or obey simple commands)
  • Blurred vision or light sensitivity

Symptoms of a concussion include headache, nausea, dizziness, sensitivity to light, confusion, different-sized pupils, blurred vision, ringing in the ears, slurred speech, slight pressure in the head, memory loss, seeing “stars,” fatigue, confusion, difficulty concentrating and feelings of sadness.
