What this article backs
In its own words
We observed the manics to have a substantial amount of thought disorder and the normals to have a modest amount, suggesting that thought disorder is probably not pathognomonic of schizophrenia. The patients with affective illness did, however, show a somewhat different pattern of abnormality. In particular, patients with affective psychosis have more prominent positive thought disorder, while the schizophrenic patients tend to have more negative thought disorder.
