title: CSF neurochemistry in depressed, manic, and schizophrenic patients compared with that of normal controls.
abstract: A total of 114 subjects (41 depressed, 20 schizophrenic, 15 manic, and 38 normal controls) underwent lumbar puncture and their CSF was analyzed for levels of tyrosine, tryptophan, homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA), 3-methoxy-4-hydroxyphenylglycol (MHPG), choline, gamma-aminobutyric acid (GABA), and calcium. Results showed that depressed patients, particularly those over 40 years of age, had lower levels of GABA than did controls, and that their level of HVA increased with age, while controls' decreased. Schizophrenic subjects tended to have higher levels of 5-HIAA and manic subjects tended to have higher levels of HVA and MHPG. Age-associated changes were found in HVA, 5-HIAA, MHPG, GABA, and choline concentrations.
