Summary

In this study an analysis is made of the quantitative changes in four areas (10, 4, 24, 17) of the cerebral cortex of patients with schizophrenia, in comparison with the normal cortex. In all areas the relation between neuron number, nuclear volume and depth was measured.

Most obvious is the finding of neuronal destruction (57%) which is minimal in the layers II and III (40%) and maximal in the layers IV and V and partially in VI (70%).

In combination with this cell-loss, the cortical thickness is diminished over about 20%. This means that also the number of other cortical elements must be reduced.

The cell-loss is random, but minimal in area 17. The nuclei are swollen except in area 17.

It is possible that this pathological-anatomical substrate is mere a characteristic of dementia, and not of schizophrenia. Further research will be directed to this problem.
