DEMENTIA PARALYTICA ACCOMPANIED BY MANIC-DEPRESSIVE AND SCHIZOPHRENIC PSYCHOSES

The Significance of Their Co-Existence.
Published Online:https://doi.org/10.1176/ajp.96.5.1043

In five clinically and serologically typical cases of dementia paralytica, there developed features strongly suggestive of manic-depressive or schizophrenic psychoses.

Long-section studies of the cases pointed to the conclusion that these features were not merely a part of the neurosyphilitic disease but were manifestations of true manic-depressive and Schizophrenic psychoses which pursued their own lines of development independent of the organic disease. Anatomic observations available in one case supported this view.

It is believed that manic-depressive or schizophrenic psychoses accompany dementia paralytica too frequently to be regarded as accidental concomitants of the latter. Apparently they are directly provoked by the organic brain disease.
