Functional magnetic resonance imaging (fMRI) reveals altered brain activity in concussed athletes. This brain imaging technique can identify underlying pathology in athletes experiencing concussion symptoms.

Area of Science:

  • Neuroscience
  • Radiology
  • Sports Medicine

Background:

  • Concussion is a common injury in athletes, often with subtle or no visible changes on standard imaging.
  • Assessing brain function post-concussion is crucial for diagnosis and management.
  • Functional magnetic resonance imaging (fMRI) offers a potential method to detect functional brain alterations.

Purpose of the Study:

  • To quantify brain activity changes in concussed athletes using fMRI.
  • To compare fMRI results between symptomatic concussed athletes and healthy controls.
  • To investigate the utility of fMRI in identifying brain pathology in concussed athletes.

Main Methods:

  • Utilized blood oxygen level dependent (BOLD) fMRI to measure regional brain activations during a working memory task.

Related Experiment Videos

  • Compared brain activity patterns in 15 symptomatic concussed athletes, 1 asymptomatic athlete, and 8 matched control subjects.
  • Quantified the average percent signal change in blood oxygen level dependent (BOLD) signals within regions of interest.

    • Main Results:

    • Symptomatic concussed athletes showed altered task-related brain activations compared to controls, even with similar task performance.
    • Some concussed athletes exhibited increased brain activity outside expected regions of interest.
    • Brain activation patterns normalized in a concussed athlete once symptoms resolved, and were comparable to controls in an asymptomatic athlete.

    Conclusions:

    • fMRI can detect functional brain abnormalities in symptomatic concussed athletes not apparent on structural imaging.
    • Working memory tasks combined with fMRI show promise for identifying underlying pathology in concussion.
    • fMRI may serve as a valuable tool for concussion assessment and monitoring recovery.
