Abstract:
:Postmortem volumetry of cortex, white matter, and basal ganglia was performed in 23 brains of schizophrenic patients and 23 brains of controls closely matched for gender, age, and hemisphere. Stereological methods were applied to serial coronal sections of complete hemispheres. We found no significant volume changes of cortex and white matter in schizophrenics. Striatal volume of schizophrenics was increased bilaterally reaching a significant level on the left side. Volumes of the globus pallidus were increased in both hemispheres reaching a significant level on the right side. After psychopathological differentiation, basal ganglia volume increase was also found in the subgroup of paranoid-hallucinatory schizophrenics.
