Investigation of Age-Related Factors Affecting Intracranial Responses Using a Human Head/Brain FE Model

Abstract

High frequency of fatal head injuries of the elderly is one of the important issues in traffic accidents in Japan. While a human head/brain FE model is a useful tool to investigate head injury mechanism, there has not been such a model that reflects the age-related changes of the brain. In this research, to get the basic knowledge to develop a head/brain model capable of representing injury mechanism of the aged brain, influence of various intracranial changes on various intracranial responses relating to brain injuries was clarified by parametric study using human head/brain FE model.
