  • Publication number: 20120052592
    Abstract: The present invention has its main object of providing a method for determining prognosis scientifically by searching an early marker for predicting neurological prognosis in order to grasp the disease state of a patient with an acute central nervous system disorder in the early stage and enabling an appropriate treatment to be performed. The method for determining the prognosis is provided in which the expression level of SH3BGRL3 in the biological fluid of the patient within 48 hours after resuscitation from cardiopulmonary arrest is measured, and the prognosis of the disorder classified into a good prognosis group and a poor prognosis group depending on the expression level or the presence or absence of the expression based on the Glasgow Outcome Scale (GOS) is predicted.
