In a total of 55 samples of cerebrospinal fluid (CSF) and an equal number of serum samples obtained from 45 patients with neurological disorders and 10 controls, folic acid and vitamin B12 were measured. A radioisotopic assay method was used. A significant decrease of CSF folic acid was noted in the group with cerebral tumors.
