A concussion is a brain injury that can be caused by a blow to the head or by any impact that causes the brain to shake violently inside the skull. Many people tend to associate concussions with sports injuries, but in fact, concussions often occur from biking accidents, car accidents, falls, and other types of collisions.

It is important to see the right medical professional right away if you suspect you may have a concussion. If concussions are not treated carefully, symptoms can continue for a longer duration of time. Further, if left untreated, concussion patients are at a greater risk of repeat concussions, which can significantly exacerbate the intensity and duration of symptoms.

You do not need to lose consciousness to have a concussion. A concussion can cause a loss of consciousness but more common symptoms may include:

  • Headache
  • Confusion
  • Difficulty concentrating
  • Dizziness
  • Sensitivity to light or noise
  • Fatigue
  • Nausea

Diagnosis and research

Concussions are currently diagnosed during neuropsychological evaluations. Unfortunately, there is no way to definitively diagnose a concussion through imaging. However, GE and the NFL have partnered to study MRI applications to better understand, diagnose, and protect against concussions. If you believe you may have a concussion and would like to contribute to cutting edge research, receive compensation (up to $400), and receive prompt clinical care at the official hospital of the New York Giants, see our Advanced MRI Applications for Mild Traumatic Brain Injury clinical trial for more information.


There is no gold standard or the same treatment for every person with a concussion. We usually recommend seeing a physician immediately after a head injury or possible concussion. Treatment usually begins with cognitive and physical rest with a gradual return to previous activities. Because concussions vary from person to person, an individual evaluation is necessary to ensure a safe, effective return to cognitive work and physical activity.
