Question

Quizplus · Accepted Answer

CT scans of schizophrenic patients have consistently shown that they have larger ventricles than nonschizophrenic subjects. This is thought to be related to brain abnormalities and decreased brain volume in certain areas, indicating that schizophrenia has neurodevelopmental origins. Other brain abnormalities have also been observed in schizophrenic patients, including altered functioning of the prefrontal cortex and increased dopamine activity in certain areas of the brain. However, these findings are not consistently observed in all studies.
