CEREBROSPINAL-FLUID SOMATOSTATIN CONCENTRATIONS IN SCHIZOPHRENIA AND SCHIZOAFFECTIVE DISORDER - THE EFFECTS OF ANTIPSYCHOTIC TREATMENT

The authors examined the effects of antipsychotic treatment on cerebrospinal fluid somatostatin like immunoreactivity (CSF SLI) in 14 schizophrenic and 3 schizoaffective patients. There was a modest but significant increase in CSF SLI in 13 out of the 14 schizophrenic patients. In addition, there was a significant positive correlation between duration of treatment and post-treatment CSF SLI concentrations. No differential response was noted in patients also treated with the anticholinergic benztropine.
