Classification of Functional Psychoses and Its Implication for Prognosis: Comparison between ICD-10 and DSM-IV
TLDR
In the cross-sectional assessment, there is a high diagnostic agreement between ICD-10 and DSM-IV in the classification of functional psychoses, and with respect to the long-term course, the delimitation of transient/episodic psychoses from schizophrenia was neither completely achieved by I CD-10 nor by DSM- IV.

TLDR
The Global Assessment of Functioning Scale showed that symptoms and social functioning in this sample approximated results from developing countries and were much better than those of developed nations.
Negative symptoms in the remission phase of bipolar disorder.
TLDR
As NS are prevalent in remitted BPD and contribute to the patients’ sociooccupational dysfunction, they require prompt detection and management.
Very long-term outcome of psychotic disorders
TLDR
Recent evidence on the very long-term outcome of psychotic disorders is in line with previous reports and suggests that prognosis remains rather modest, although there are several limitations of current research regarding outcome definitions and study design.
The EPPIC follow-up study of first-episode psychosis: longer-term clinical and functional outcome 7 years after index admission.
TLDR
The relatively positive outcomes are consistent with a beneficial effect of specialized early intervention programs; however it is premature to draw firm conclusions.
Negative Symptoms Across the Schizophrenia Spectrum: Phenomenological and Neurobiological Perspectives
TLDR
The historical and current conceptualization of the negative symptoms of schizophrenia are explored, including the recent formulation of two core subdomains of negative symptoms: Diminished expression and Amotivation, and a growing body of evidence for the neurobiological underpinnings of these symptoms from across the schizophrenia spectrum is explored.
The Negative Symptoms of Schizophrenia: Category or Continuum?
TLDR
Evidence that negative symptoms show a continuous distribution from apparently healthy subjects to those with a fully developed clinical syndrome justifies exploring a dimensional approach with respect to its clinical and scientific utility.

Outcome of schizoaffective disorder at two long-term follow-ups: comparisons with outcome of schizophrenia and affective disorders.
TLDR
The data suggest that when mood-incongruent, schizophrenic-like psychotic symptoms are present in the acute phase, they predict considerable difficulty in outcome, even when affective syndromes are also present, as in schizoaffective disorder.
Psychopathological and social outcome in schizophrenia versus affective/schizoaffective psychoses and prediction of poor outcome in schizophrenia Results from a 5‐8 year follow‐up
TLDR
The hypothesis that patients with the diagnosis of schizophrenia have, as a group, the poorest degree of psychopathological disturbances and social maladjustment is confirmed; however, there is a large subgroup with a favourable outcome.
Long-term outcome of major psychoses. I. Schizophrenia and affective disorders compared with psychiatrically symptom-free surgical conditions.
TLDR
The present data on long-term outcome of the typical cases can be used to compare outcome of other psychiatric disorders, such as undiagnosed psychoses, having mixtures of schizophrenic and affective features, to charify the understanding of undi diagnosed psychoses.

TLDR
It is concluded that the diagnostic classifications used were of limited value in predicting outcome in functional psychosis.
The deficit syndrome in schizophrenic and nonschizophrenic patients: preliminary studies.
TLDR
Preliminary data indicate a possible link between light sensitivity and the deficit syndrome, independently of diagnoses, and suggest the nonspecificity of primary enduring negative syndromes.
Course and outcome in bipolar affective disorder: a longitudinal follow-up study.
TLDR
Many contemporary bipolar patients demonstrate gradual improvement in the first several years after hospitalization, however, a subgroup approaching 60% still experience poor posthospital adjustment in one or more areas of functioning.

TLDR
The findings reported suggest that after the initial episode the course of schizophrenia is relatively stable, and the data support neither concepts of progressive deterioration nor progressive amelioration.
The deficit state in first-episode schizophrenia.
TLDR
The prevalence of the deficit syndrome in first-episode schizophrenia varies depending on the criteria used and is lower than that previously described in more chronic patient samples.
