The cerebrospinal fluid exists in the central tube, subarachnoid cavity, ventricle and spinal cord to maintain relative sta-bility of cranial pressure has important role.When the nervous system disease, abnormal glucose metabolism, produce lactic acid, blood brain barrier damage after cerebrospinal fluid lactic acid concentration increases, therefore, through the detection of cerebrospinal fluid lactic acid concentration to assess the clinical nerve injury severity, concentration of cerebrospinal fluid lactic acid can be applied to a va-riety of nerve disease curative effect and prognosis evaluation, has important clinical value.
