The ventricular system in chronic schizophrenic patients. A controlled computed tomography study

Twenty-three chronic schizophrenic patients and 23 controls, all males
between 20 and 40 years of age, were evaluated by CT scan. The lateral,
third and fourth ventricles, the Sylvian fissures, and the largest sulcus
from each of the frontal, parietal, and occipital lobes, were measured in
order to determine whether the previously reported ventriculomegaly in
schizophrenics was perhaps due to a disturbance of CSF flow or to atrophy,
two common causes of ventricular enlargement. We found that in the
schizophrenic group the third and fourth ventricles and both Sylvian
fissures were significantly enlarged, but not the lateral ventricles or
cerebral sulci. Our data suggest that these ventricular changes are not due
to a disturbance of CSF flow or to cerebral atrophy. Other possible
explanations are discussed.
