In 17 antipsychotic-naive schizophrenic patients, the scores of positive and negative symptoms of schizophrenia were correlated with relative regional cerebral perfusion measured by 99m-Tc-ECD (ethyl cysteinate dimer) single photon emission computed tomography (SPECT). Scans were performed in subjects at rest. The negative symptom dimension was significantly correlated with a decreased level of perfusion in the left thalamic region. Other non-significant trends were also observed; the positive… CONTINUE READING
