Summary
Traumatic brain injuries (TBI) are related to strong angular accelerations/deaccelerations causing extreme strain/stress values along brain tissues. This can result in the affectation of wide intracraneal structures by mechanical damage, hemorragies and inflamation processes, particulary, in the axonal tracks. This set of alterations are called diffuse axonal injury that is behind severe conditions such as loss-of-consciousness in vegetative state/unresponsive wakefulness and severe disability after mild TBI.
The assesment of the injury and the patient prognosis in these conditions could be enhanced by using computational models reproducing the dynamics of the cerebral tissue damage (ref kleiven). In this work, we propose an specific finite element-based (FEA) model to study the biomechanical properties of axonal track damage related to the severe grading of diffuse axonal injury (Adams 1989 et al.). In particular, we aim to model (1) grey-white matter interfaces, (2) corpus callosum and (3) brain stem damages.
