Many patients are unable to recover completely their social function following head trauma caused by traffic accidents. Prediction on occurrence of higher brain dysfunction is important for those who will be able to return home after head trauma. In this study we tried to reproduce injury condition in cases with traumatic higher brain dysfunction caused by traffic accidents and discussed the relationship between the mechanical impact to brain and higher brain dysfunction. We reproduced 6 cases using combination of multibody analysis and finite element (FE) head modeling. As a result, the strain on the frontal lobe caused by an injury condition was suggested to contribute to the onset of attention disturbance during the chronic phase of treatment. This method has the possibility to predict the onset and severity of traumatic higher brain dysfunction.
