Cyclic AMP in the CSF of patients with schizophrenia
J Biederman, R Rimon, R Ebstein, RH Belmaker and JT Davidson
The dopamine hypothesis of schizophrenia proposes that schizophrenia is
associated with increased brain dopaminergic function. Because dopamine is
thought to stimulate the production of cyclic AMP in the brain, we
hypothesized that CSF cyclic AMP would be increased in schizophrenia.
Cyclic AMP in the CSF was determined in 19 schizophrenic patients who had
not received neuroleptic treatment in the preceding two weeks. No
significant difference could be shown between CSF cyclic AMP in these
patients and CSF cyclic AMP in 10 psychiatrically normal controls.
