MATHEMATICAL MODELING OF NORMAL-PRESSURE HYDROCEPHALUS AT DIFFERENT LEVELS OF THE BRAIN GEOMETRY DETALIZATION

This paper describes the use of a multiphase model of poroelasticity meant for the brain substance and based on medical data to study the displacement of a ventricle wall in the brain and the value of pressure on it. The dependence of displacement and pressure on the parameters of the model in normal-pressure hydrocephalus is studied. It is shown for different levels of the brain geometry detalization that the simplified geometry of the brain allows one to estimate critical pressures and displacements in the case of more complex geometry.
