Impact of lithium therapy on core psychotic symptoms of schizophrenia
FP Zemlan, J Hirschowitz, FJ Sautter and DL Garver
The authors have previously reported that a sub-group of schizophrenic-
like patients respond favorably to lithium therapy: furthermore, psychotic
patients who respond to lithium demonstrate appreciable improvement during
the first seven days of treatment. The present study investigated which
symptoms of schizophrenia improved quickly during lithium treatment. We
found that patients who do respond to lithium show significant improvement
in the core symptoms of psychosis-- hallucinations, delusions and formal
thought disorder--during the first seven days of treatment, thus allowing
early identification of 88 per cent of schizophrenic patients who
ultimately respond to lithium and 91 per cent of those who do not.
