Owing to rapid advancements in neurosurgery, the number of patients with severe
brain injury due to cerebrovascular disorder, whos lives can be saved, has increased. Along with this phenomenon, however, the number of patients with persistent vegetative state has been increasing, and thus constitutes an important issue. No effective treatment method for persistent vegetative state has been established but some reports have recently shown that spinal epidural stimulation and median nerve stimulation are effective. However, the mechanisms of action of these methods, activation of nerve cells and increased cerebral blood flow, are unknown. We employed median nerve stimulation for a patient with persistent vegetative state due to an injury sustained in a traffic accident and obtained interesting results in terms of the patient’s cerebrospinal fluid (CSF) findings.
