The problem of the senescence's influence on schizophrenia and the right to detach this variable from those who take care of temporal evolution is complicated. From a population of 99 schizophrenic patients (DSM III criteria's) having most of 60 year old and most of 20 years schizophrenia's disease evolution; we have study the whole or partial imputability to the senescence of residential statute's modification; frequency, reason, duration of hospitalization's change, psychotic's symptom levelling; and therapeutic's instability.

Schizophrenia occurring in childhood and adolescence has similar diagnostic, prognostic, and treatment ramifications as those noted with adult-onset schizophrenia. In assessing a child or adolescent suspected of having schizophrenia, care must be given to document DSM-III-R diagnostic criteria within the developmental framework of the patient's functioning, while thoroughly evaluating for other potentially confounding disorders or conditions. Antipsychotic therapy is the only specific treatment for schizophrenia, and should be a fundamental component with a multimodal treatment program that also addresses the psychological, social, and educational needs of the patient and his or her family. Strategies for medication management vary depending on several factors, including the stage of the disorder, noted or potential side effects, and the response of the patient to treatment, and need to be coordinated for the long term by a child or adolescent psychiatrist familiar with the diagnosis and treatment of schizophrenia in this age group.

Eleven patients with DSM-III-R schizophrenia were entered into a 4-day tryptophan (TRP)-deficient diet. The diet lowered total plasma TRP levels in all patients; during the diet phase, there was a greater than 50% reduction in mean total plasma TRP levels from the pre-diet phase. The low-TRP diet improved performance on the Stroop Color and Word Test. These data are especially intriguing in view of the suggestion that a deficit in color-word naming is related to frontal lobe dysfunction and the possible occurrence of frontal lobe abnormalities in patients with schizophrenia. Interestingly, depressive symptomatology did not emerge on the TRP-deficient diet, despite the lowering of total plasma TRP levels. There were statistically significant improvements noted on objective ratings of the severity of psychotic symptomatology; however, these statistical improvements were without obvious clinical significance, as the magnitude of the changes on the behavioral ratings were minimal. The results of this study suggest that there might be some adjuvant potential for a low-TRP diet in the treatment of schizophrenia, and that schizophrenia or antipsychotic medications might offer some protection against the depressive effects of a TRP-deficient diet.

A cohort of schizophrenic patients consecutively admitted to a mental hospital for the first time in 1925 was investigated in search of symptoms and traits with prognostic meaning. Since Leonhard's diagnostic system was applied, cases with mixed symptoms and a favourable outcome were excluded as being neither schizophrenic nor manic-depressive. Owing to the admission policy then prevailing, cases with clinically less striking and socially less deleterious features were underrepresented. The sample (n = 70), so demarcated, was still considered fairly appropriate for the purpose of a differential study of outcome in nuclear schizophrenia with a life-long follow-up. The best outcome group consisted of 33% of the sample; 24% formed an intermediate group, and 43% profoundly deteriorated with continuous psychotic symptoms and a total loss of social function. Marriage before index admission was the only characteristic related to a favourable outcome. Nuclear schizophrenic symptoms, thought disturbance, blunted affect and all catatonic symptoms listed in DSM-III were related to an unfavourable outcome. When prognostic subgroups were compared pairwise, no favourable trait was detectable, and there were no decisive differences between the group with the best outcome and the intermediate group. When these 2 groups were compared with the group with worst outcome, however, significant differences arose with respect to unfavourable characteristics. Predictions using a discriminant analytic procedure yielded the same results. The hypothesis that affective and atypical signs would also have prognostic meaning in nuclear schizophrenia was disproved.

Three hundred and twenty-six consecutively admitted patients with functional psychotic illnesses to which no diagnostic classification had been applied were followed up after 2.5 years. They were examined in social, clinical and psychological terms and the CATEGO programme and DSM-III criteria were applied to data concerning the index episode to derive diagnostic classifications. The deterioration in occupational functioning and the hospital careers of patients with diagnostic classifications of schizophrenia were worse than those in the other groups and positive and negative features were also more severe in patients with a classification of schizophrenia. By contrast, no differences in psychological test performance were found between the groups based upon diagnostic classification. Impaired psychological test performance was found and it was strongly related to concurrent mental state abnormalities, particularly negative symptoms. It is concluded that the diagnostic classifications used were of limited value in predicting outcome in functional psychosis.

The case of a patient with symptoms suggestive of a dissociative disorder is presented. The consultant reviews the diagnosis of multiple personality disorder (MPD) as defined in DSM-III-R and DSM-IV in relation to the patient's dissociative states, hallucinations, memory loss, and other symptoms. He then highlights the distinctions among MPD, schizophrenia, borderline personality disorder, major depression, and complex partial seizures. After presenting the conceptualization of MPD as a chronic posttraumatic stress disorder, he concludes with a review of treatment approaches that address the traumatic history and that involve hypnosis to gain access to and control dissociative states.

The relation of specific MMPI scores to attention, concentration, and memory was assessed in an inpatient psychiatric sample diagnosed by DSM-III-R criteria as having schizophrenia, chronic undifferentiated type (n = 22); schizophrenia, paranoid type (n = 17); and schizoaffective disorder (n = 20). MMPI indices that are used widely to infer cognitive efficiency--including Scales 2 (Depression), 8 (Schizophrenia), SC-PT, D4 (Mental Dullness), SC2A (Lack of Ego Mastery, Cognitive), PSY (Psychoticism) and ORG (Organic Symptoms)--were investigated in relation to actual performance on Digit Span and subtests of the Wechsler Memory Scale (WMS, Russell's Revision). Weak correlations emerged (maximum r = .31, p less than .05), which suggests that scores on these MMPI measures may not provide a reliable basis for inferring attention and memory functioning.

The symptomatic response to standard antipsychotic treatment was assessed over the first 4 weeks of hospitalisation in 39 patients with DSM-III schizophrenia, active phase, using the Brief Psychiatric Rating Scale (BPRS). While highly significant improvement was noted overall, 36% of patients either did not improve or worsened. Furthermore there was no diminution in the withdrawal-retardation factor of the BPRS. Patients experiencing their first admission to hospital, all with recent-onset illness, were then compared with patients who presented with a recurrence and had illness of at least 3 years duration. Despite similarities in overall response, withdrawal-retardation scores did not diminish in recent-onset patients, in contrast to multiple admissions who demonstrated significant improvement. These findings suggest greater responsiveness of negative symptoms to treatment in patients with longstanding illness, and possibly a poorer prognosis in first admission patients with deficit manifestations.

A genetic case-control study was conducted in a group of patients with schizophrenia (n = 67; DSM-III) and psychiatrically normal controls matched for ethnicity (n = 84), living in the same geographical area. Using three different DNA polymorphisms of the gene encoding porphobilinogen deaminase (PBGD), a candidate gene for schizophrenia, an association with schizophrenia could not be detected. No significant associations were detected even after sub-division of the cohort by ethnicity and by gender.

Cerebrospinal fluid (CSF) corticotropin releasing hormone (CRH), somatostatin (SRIF), and thyrotropin releasing hormone (TRH) were measured by specific radioimmunoassay methods in 86 patients who met DSM-III-R criteria for schizophrenia or schizophreniform disorder and in 30 neurologic controls. The multivariate CSF peptide concentration was significantly different in patients compared with controls, but none of the individual variable differences reached statistical significance when analyzed separately. There were no significant CSF neuropeptide differences among patients with various schizophrenic subtypes. Neither global severity of illness nor individual symptoms were correlated with CSF neuropeptide concentrations. Although schizophrenic patients showed a pattern of mildly lower SRIF and TRH levels in their CSF, together with a weak tendency for higher CSF CRH values, these peptide changes did not appear to be specifically related to the core features of schizophrenia.
