Brain concussion may cause structural brain changes, not just functional ones. Modern imaging reveals persistent blood flow disturbances after head injuries, suggesting underlying physical damage.

Area of Science:

  • Neuroscience
  • Neurology
  • Traumatology

Background:

  • Modern understanding of brain concussion has evolved over five decades.
  • Previous research suggested concussion might cause purely functional brain damage.

Purpose of the Study:

  • To review modern views on brain concussion.
  • To investigate structural changes and persistent disturbances following mild craniocerebral injuries.

Main Methods:

  • Development of an experimental model for light craniocerebral injuries.
  • Application of Single-Photon Emission Computed Tomography (SPECT) for diagnostic imaging.

Main Results:

  • Demonstrated structural changes in the central nervous system post-concussion.

  • Identified persistent disturbances in regional cerebral blood flow using SPECT.
  • Evidence suggests mechanisms causing perfusion changes may also lead to axonal disorders and blood-brain barrier breakdown.

    • Conclusions:

    • Results challenge the concept of "purely functional" brain damage after mild head injury.
    • Persistent cerebral perfusion changes indicate underlying structural alterations.
    • Further research aims to correlate electrophysiological, vascular, and biochemical changes with behavioral disorders in post-concussion syndrome.
