The Early Symptoms of Schizophrenia
Abstract
Since Bleuler introduced his concept of schizophrenia in 1911, there has been a steady growth of clinical and experimental data relating to this disease. However, the literature dealing with early diagnosis is sparse and as yet there is no general agreement as to what symptomatology constitutes the early clinical picture. Older texts (Kraepelin, 1919; Bleuler, 1911) do not elaborate early diagnosis, dwelling more on distinguishing schizophrenia from other disease entities. Likewise, more recent texts tend to refer to the early stages very briefly in rather vague terms, signifying the development of the disease over the first few years from its onset. Although practice varies, the diagnosis of schizophrenia is often reserved until Bleuler's primary symptoms of disordered volition, thinking and affect appear overtly, by which time there may be also some evidence of deterioration. It is recognized, however, that these symptoms may take years to appear (Gillies, 1949) so that early diagnosis cannot readily be made by using these criteria.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
