Pathological findings can include subarachnoid hemorrhage, subdural hematoma, extradural hematoma, intraventricular hemorrhage, effacement of ventricles, cerebral edema, bradycardia, elevated blood pressure and intracranial pressure, midline shift, cerebral contusion, skull fracture, cerebellar damage, BBB disruption, hippocampal volume loss, increased serum cytokine levels, elevated Glial fibrillary acidic protein (GFAP), myelin basic protein (MBP), and neurofilament light (NfL) deposition. Here, GFAP is linked to subarachnoid hemorrhage.
