[Study on dopamine metabolite in cerebrospinal fluid of schizophrenics and epilepsics].

The concentration of dopamine (DA) metabolite-homovanillic acid (HVA) in cerebrospinal fluid (CSF) of 40 patients with schizophrenia 27 with epilepsy and 15 controls without disorders of CNS was reported. The results showed that there were no significant differences in mean levels of HVA among the three groups. It is suggested that both schizophrenia and epilepsy are not abnormal in total level of DA metabolism.
