TBI Can Occur Before Direct Contact

Researchers at Sandia UNM laboratories used complex tomography scans to reveal the brain injury can occur before the head comes into contact with an object. The pressure from the motion alone can cause diffuse injuries throughout the brain:

“In discussions between Taylor and Ford, it became apparent that different types of cell damage might occur depending on the type of stress to which the cells are exposed. “Isotropic stress,” commonly called pressure stress, imposes density changes that can damage a cell’s internal structure. “Shearing stress” acts as a tearing mechanism that damages the cell wall and membranes, giving rise to apoptosis, or cell death. Both are likely at play in most incidents leading to TBI.”
