Patients referred over 28 months from nine medical centres for a trial of prophylactic neuroleptic medication following first episodes of schizophrenic illness (462) were assessed with the Present State Examination, WHO scales for disability, past history, and socio-demographic factors, and a rating of disturbed behaviour; 253 fulfilled the study criteria; of the 209 who did not, 54 did not meet the diagnostic criteria, 65 had a history of a previous episode, and in 15 the psychotic illness was… 
West London first-episode study of schizophrenia. Clinical correlates of duration of untreated psychosis.
TLDR
There was little evidence of any association between either DUP or DUI and progressive deterioration in the schizophrenic illness or the development of resistance to initial drug treatment.
Patients with a first episode of schizophrenia spectrum psychosis and their pathways to psychiatric hospital care in South Germany
TLDR
In Germany, a large number of mental health professionals in private practice or different services of psychosocial contact facilities exist in every region and general practitioners are not so important as a link to psychiatric care, although they seem to be functioning well if it is necessary.
Incidence, clinical characteristics, and short-term outcome of first-episode schizophrenia
TLDR
The strongest predictive variable for rehospitalization was gradual versus acute type of first onset, and the sample was quite heterogeneous with regard to psychosocial, clinical, and demographic data and short-term outcome.
Premorbid and onset features of first-episode schizophrenia.
TLDR
Systematic characterization of the earliest manifestations of schizophrenia may be important in identifying subgroups of patients with a similar course of illness, and may ultimately facilitate diagnosis, treatment, and understanding of the pathophysiology of schizophrenia.
Dangerous Behaviour Preceding First Admissions for Schizophrenia
TLDR
Of 253 patients in their first schizophrenic episode, 52 behaved in a way threatening to the lives of others before their admission to hospital, and life-threatening behaviour was more common where the patient had been ill for longer, and where there were delusions of being poisoned.
Pathogenesis of schizophrenia: a psychopathological perspective
TLDR
In genetically predisposed individuals, affective and perceptual disorders are prominent before any behavioural or subjective change that usually characterises the shift to schizophrenic prodrome or active illness.
Comorbidity in psychosis at first hospitalization.
TLDR
Comorbidity is common and may be a useful predictor of the outcome of a first episode of psychosis, while those with medical comorbidities had fewer symptoms at discharge.
The natural course of schizophrenia: a review of first-admission studies.
TLDR
Methodological improvements in first-admission research are suggested, including separating the analyses of first-episode patients from those with past psychotic experiences, employing longitudinal methods for deriving diagnosis, and enlarging the samples either by multisite or multicenter collaborations or by pooling data across studies.
Cantabria First-Episode Schizophrenia Study: three-year follow-up
TLDR
The outcome of schizophrenia is less pessimistic than was originally thought and being male and having low social class tended to be associated with poor clinical outcome.
First-episode schizophrenia: I. Early course parameters.
TLDR
Early course parameters of a Norwegian first-episode sample demonstrated strong gender differences, with male patients having significantly higher frequency of single marital status, lower educational status, schizophrenia, early age at onset, and lower Global Assessment of Functioning scores the last year before hospitalization.
