Cerebrospinal Fluid Pressure Distribution in Head During External Impacts

ORAL

Abstract

Mild Traumatic Brain Injury (mTBI) has a significant contribution to injury-related disabilities that impact a substantial number of patients in many age groups per year. The brain as soft tissue is located inside skull. The subarachnoid space between brain and skull contains Cerebrospinal Fluid (CFS). During a sudden impact, this fluid which is surrounding the brain experiences stress variations that can affect brain tissue depends on the dynamic of impact, including rotational and translational acceleration. In this study the interaction between skull, brain, and CFS during mTBI incident is investigated to better. Cerebrospinal Fluid pressure distribution, brain displacement and motions, and acceleration during the impact are studied by taking into account the interaction of CFS as fluid, and brain tissue as solid.
