Apparent recovery from brain changes following blast concussion is followed by secondary changes

Takeaway

  • Compared with controls, people with a concussion caused by a combat blast had a u-shaped imaging change trajectory: fractional anisotropy reductions shortly after injury and at 5 years, but not at 1 year.

Why this matters

    Results suggest that people with apparent recovery following combat concussive blast exposure should be monitored for secondary brain changes and provide possible insights into the ‘accelerated brain-aging’ theory.
