Normal ventricles in young schizophrenics.

The CT scans of 11 schizophrenics and 26 controls were evaluated for both linear (Evan's and cella media ratios) and volume (planimetry and grid ratios) measurements of ventricular size. There were no differences between the two groups on any of the measures obtained. These results are discussed in relation to previous reports showing ventricular enlargement in schizophrenics. The relatively younger age and briefer period of hospitalization in this present sample are suggested as variables possibly associated with these findings.
