A diganosis commonly used in the Scandinavian countries, reactive psychosis, is described. Systematic personal follow-up studies from Scandinavia have clearly demonstrated that the clinical and social course is more favourable in this diagnostic group than in schizophrenia, while the course in schizophreniform psychoses in between. The Scandinavian concept of schizophreniform psychosis and of schizophrenia is presented and discussed.

In human beings, amphetamine can induce both schizophreniform psychosis and oral-facial dyskinesia resembling tardive dyskinesia, while neuroleptic agents reduce the manifestations of both conditions. This suggests that such psychosis and movement disorder may occur by the same or very similar mechanisms. It is thought that tardive dyskinesia may result from neuroleptic-induced denervation hypersensitivity to dopamine. The author cites evidence suggesting that amphetamine may act on dopaminergic pathways in the CNS to produce a denervation hypersensitivity like that caused by neuroleptic agents. Clinical evidence compatible with a denervation hypersensitivity hypothesis of schizophrenia is then discussed.

A Danish centre contributed 12 cases to a Nordic multicentre investigation concerning the psychotherapy of psychoses. Patients admitted consecutively to the psychiatric hospital with the diagnoses of schizophrenia, schizophreniform psychosis or schizoaffective psychosis were offered psychotherapy at least once weekly for two years in addition to the other treatment modalities administered. In the Danish design, the process of supervision in relation to the processes of psychotherapy was investigated. In the present article, examples are presented illustrating how core psychotic mechanisms in the patients are reflected not only in process-facilitating but also in process inhibiting psychotherapeutic interventions. The data of the investigation are these interventions which are written down prospectively in the summaries of the supervision.

Seventy-two patients fulfilling the DSM-III criteria for schizophrenia and schizophreniform psychosis were admitted to a multicentre, double-blind controlled study to evaluate the efficacy and safety of remoxipride in comparison to haloperidol. The mean daily dose of remoxipride at the end of treatment was 353 mg and of haloperidol, 11 mg. Patients were assessed each week on the Brief Psychiatric Rating Scale (BPRS), the Clinical Global Impression (CGI) and the symptoms checklist. No significant differences in efficacy were found between the two treatments. The median total BPRS score in the remoxipride group was 25 at start of active treatment and 17 at the last valid rating (n = 31). For the haloperidol group the corresponding figures were 24 and 15 (n = 29). According to the CGI, 40% of remoxipride patients and 50% of haloperidol patients were much or very much improved. Treatment-emergent extrapyramidal symptoms, such as akathisia and rigidity, occurred significantly more frequently, and were more severe during treatment with haloperidol than with remoxipride (p = 0.012 and 0.024, respectively). Haloperidol-treated patients reported significantly more drowsiness and increased sleep during treatment (p = 0.026 and 0.012, respectively). No statistically significant differences were seen in endocrine or autonomic symptoms. Remoxipride seemed to be as effective as haloperidol, had a lower frequency of side effects, and was used safely in the dose range 150-600 mg/day.

Admissions to a mother-baby unit in a psychiatric hospital were reviewed over a 51 month period. Forty-four mothers (3 admitted twice) and 44 babies were admitted. Eighteen women were diagnosed as having major depression (1 admitted twice), 14 with schizophreniform psychosis, 8 with schizophrenia (2 admitted twice), 4 with bipolar disorder, 2 with anxiety disorders and in 1 diagnosis was deferred. Data are presented from these women's background and that related to pregnancy, as well as duration of stay and treatment in the unit. A description of the unit is also included.

Amphetamine induced psychosis has for the past 30 years provided a useful model for the study of schizophrenia. The amphetamine model, however, has been shown to have a number of shortcomings including an inability to model the deficit symptoms of schizophrenia. PCP (phencyclidine) has been shown to be capable of inducing a schizophreniform psychosis consisting of both productive and defict symptomatology. PCP induced psychosis, therefore, may provide a useful model of schizophrenia. This paper reviews the literature concerning the PCP model of schizophrenia and provides some independent confirmation of the ability of PCP to modulate mesocortical dopaminergic activity. Since PCP appears to mediate its CNS effects via a subclass of glutamate receptors, a possible glutamate theory of schizophrenia is proposed.

The relationship of cognitive impairment to the course of schizophrenia remains uncertain. By studying psychotic adolescents, 90% of whom were hospitalized for the first time, we hoped to reduce the influence of such confounding variables as lengthy disease process, neuroleptic treatment, and institutionalization. 39 psychotic adolescent subjects who fulfilled DSM-III criteria for schizophrenia, schizophreniform psychosis, paranoid schizophrenia, or atypical psychosis were compared to 41 non-psychotic adolescent psychiatric controls. Subjects were administered the Wechsler Intelligence Scale for Children-Revised, Peabody Individual Achievement tests of reading, reading comprehension, and mathematics, Bender-Gestalt, and Purdue Pegboard test within 3 weeks of admission to a psychiatric hospital. Performance IQ was significantly lower in the psychotic group (72 versus 93, P = 0.03). Thus, the IQ pattern in adolescent psychotic patients at an early stage in their illness was similar to the pattern displayed by chronic adult schizophrenic patients. Results were not consistent with theories of left hemisphere involvement in schizophrenia. Academic achievement was similar in both groups despite marked differences in performance IQ. Psychotropic medication had no significant impact on the results. In summary, deficits in processing novel material seem at the very least to be present at the onset of the psychotic disorder, though they may be non-progressive thereafter.

This paper deals with the prognosis of schizophrenic psychoses in Helsinki in 1950-1955, 1960-1965, 1965-1970, 1970-1975, and 1975-1980. The first 4 cohorts each include a sample of 100 patients taken in 1950, 1960, 1965, and 1970. The patients were admitted for the first time to a psychiatric hospital because of schizophrenic and paranoid psychoses. The 1975 material includes all (n = 94) first admissions for schizophrenia, fulfilling the DSM-III criteria of schizophrenia or schizophreniform psychosis.

In a study of cases of recent onset of schizophrenia, schizophreniform psychosis and hypomania (DSM-III criteria), threatening life events were significantly related to the onset of schizophreniform psychosis but not schizophrenia. The results also suggest that threatening events may precipitate hypomanic episodes.

In 10 patients with Parkinsonism, treatment with L-dopa was associated with a rise in the skin conductance level and its fluctuations, an increased electromyographic activity in the frontalis muscle, and with faster reaction times. The change of skin conductance in response to a loud noise also increased and its habituation to the repetition of the stimulus was delayed. One patient developed a schizophreniform psychosis and showed high arousal and absent habituation. It is possible that dopamine is the transmitter associated with the arousal reaction and that it plays a part in the pathogenesis of schizophrenia.
