BackgroundThe aim was to examine in a population of schizophrenic patients the clinical correlates of ‘neurodevelopmental’ schizophrenia and their relationship to putative aetiological factors.MethodPremorbid social adjustment, premorbid schizoid and schizotypal personality traits, and the obstetric history of 40 schizophrenic patients and their 102 sibs were assessed through interviews with their mothers. Patients' premorbid level of intelligence was assessed by the National Adult Reading Test and current symptoms by the Positive and Negative Syndrome Scale and the Subjective Deficit Syndrome Scale.ResultsPatients had more schizoid and schizotypal traits than their sibs. They showed a deterioration in social adjustment between childhood and adolescence; sibs' social adjustment improved. There were statistically significant associations between current negative schizophrenic symptoms, premorbid deterioration in social adjustment, and schizoid and schizotypal personality traits, and between an early age of onset of illness and the same premorbid assessments. There was no evidence that patients with a family history of severe mental illness leading to hospitalisation, or a history of definite obstetric complications, had poorer premorbid functioning or more severe current symptoms.ConclusionsWe have confirmed clinical correlates of ‘neurodevelopmental’ schizophrenia but found no association between these and obstetric complications or a family history of severe mental disorder.

The main objective of the present study was to compare the distribution of underlying factors such as neurological soft signs, obstetric complications, and family history of psychiatric disorders between two groups of schizophrenic patients and patients with prolonged methamphetamine-induced psychosis. In a case-control study, 30 patients with prolonged methamphetamine-induced psychosis and 30 patients with schizophrenia were selected. Data were collected through a demographic questionnaire, the Buchanan and Heinrichs’ Neurological Evaluation Scale (NES), the Lewis-Murray’s Obstetric Complications Scale (LMOCS), and the Weissman’s Family History Screen (FHS). Mean scores of the neurological soft signs (±SD) in the two groups of schizophrenic patients and patients with prolonged methamphetamine-induced psychosis were 15.7±8.7 and 11.7±6.2, respectively (P=0.040), and a significant difference was observed in the sensory integration between the two groups (P=0.022). Obstetric complications revealed similar distributions in the two groups. Patients with prolonged methamphetamine-induced psychosis reported higher prevalence of alcohol and other substances use disorders (P=0.003 and P=0.001, respectively) in their close relatives; however, the distributions of other disorders were not statistically different between the two groups’ close relatives. Similarities and differences in certain aspects were observed between the two groups, suggesting susceptibility for psychosis in patients with prolonged methamphetamine-induced psychosis; yet we found diversities that distinguish the two disorders. © 2019 Tehran University of Medical Sciences.

Obstetric histories of 54 schizophrenic patients and 114 siblings were obtained from their mothers and scored using the Obstetric Complications Scale. There was no statistically significant difference in the proportion of schizophrenic patients (35%) and siblings (29%) who had at least one definite obstetric complication. There was no evidence that schizophrenic patients with a history of obstetric complications were less likely to have a first-degree relative with a history of psychiatric illness leading to in-patient care. Schizophrenic patients with a history of obstetric complications were more likely to have drug-induced Parkinsonism. There was a trend for tardive dyskinesia to be more common in those schizophrenic patients with no obstetric complications but a family history of schizophrenia.

AbstractObjectiveWe sought to explore whether obstetric complications (OCs) are more likely to occur in the presence of familial/genetic susceptibility for schizophrenia or whether they themselves represent an independent environmental risk factor for schizophrenia.MethodsThe presence of OCs was assessed through maternal interview on 216 subjects, comprising 36 patients with schizophrenia from multiply affected families, 38 of their unaffected siblings, 31 schizophrenic patients with no family history of psychosis, 51 of their unaffected siblings and 60 normal comparison subjects. We examined the familiality of OCs and whether OCs were commoner in the patient and sibling groups than in the control group.ResultsOCs tended to cluster within families, especially in multiply affected families. Patients with schizophrenia, especially those from multiply affected families, had a significantly higher rate of OCs compared to normal comparison subjects, but there was no evidence for an elevated rate of OCs in unaffected siblings.ConclusionOur data provides little evidence for a link between OCs and genetic susceptibility to schizophrenia. If high rates of OCs are related to schizophrenia genes, this relationship is weak and will only be detected by very large sample sizes.

Abstract Background: Previous studies have linked schizophrenia to EAAT1 and EAAT2 genes. The aim of this study was to investigate the relationship between polymorphism of these two genes and schizophrenia in Chinese Han population. Methods: A total of 233 schizophrenic patients and 342 healthy controls were enrolled. Six SNPs including rs2269272、rs2731880、rs12360706、rs3088168、rs12294045、rs10836387 were genotyped by SNaPshot. Clinical features were collected using a general demographic questionnaire. Symptoms were measured by the Positive and Negative Syndrome Scale (PANSS), and cognitive function was assessed by Matrics Consensus Cognitive Battery (MCCB). Results: The allele frequency of EAAT1 rs2731880 was significantly different between patients and controls (c2=4.205, R=0.040). The allele and genotype frequency of EAAT2 rs12294045 were significantly different between case and control group (allele:c2 = 8.144，R = 0.004; genotype: c2 = 8.054, R = 0.02). Patients with family history of psychosis were more likely to have the CT genotype of rs12294045 than patients without family history of psychosis，while patients with CT genotype of rs12294045 had significantly lower scores of verbal learning and working memory.Conclusions: The polymorphism of EAAT1 and EAAT2 genes in Chinese Han population may be associated with schizophrenia. The CT genotype of EAAT2 rs12294045 may be one of the risk factors for verbal learning memory and working operational memory dysfunction in patients.

SummaryThe aim of this study was to test that deficit (D) schizophrenic patients as defined by Carpenter et al had a higher prevalence of family history of schizophrenia but less obstetric complications than non-deficit (ND) patients. A lower rate of obstetric complications but an excess of schizophrenic and a higher rate of alcoholism family antecedents in 18 D patients compared to 23 ND patients were found. These results could suggest that there is a different weight of genetic and early environmental factors in D and ND patients.

Two cases of psychotic illness in association with the karyotype triple X showed specific diagnostic and management problems as well as obstetric complications, EEG abnormalities, and lack of a family history of psychiatric disorder. Routine karyotyping during the investigation of psychosis is becoming relevant to psychiatric practice as research reports increasingly feature genetic and chromosome anomalies in association with schizophrenic psychoses.British Journal of Psychiatry (1992), 160, 554–557

The Relationship

Objective: It has been hypothesized that patients with a diagnosis of schizophrenia who have a positive family history for schizophrenia will show greater reactivity of their symptoms to increasing levels of stress or negative affect than will patients without such a family history. In the past this hypothesis has only been tested through manipulations of negative affect in laboratory settings. In this paper we test this hypothesis using longitudinal clinical data. Method: Data were derived from an earlier longitudinal study using monthly assessments of daily stressors (Hassles Scale) and symptom measures (the Scale for the Assessment of Positive Symptoms and the Scale for the Assessment of Negative Symptoms). We compared longitudinal stress to symptom relations in 12 patients with schizophrenia for whom a positive family history of schizophrenia could be identified with 12 matched schizophrenic patients without any known family history of psychiatric illness. Results: There was evidence that patients with a family history of schizophrenia demonstrated a stronger relation between stress and total score on the Scale for the Assessment of Positive Symptoms. This difference appears to have primarily reflected a greater reactivity to stress of reality distortion symptoms in the positive family history group. The two groups did not differ in apparent reactivity to stress of the disorganization and psychomotor poverty dimensions of symptomatology. Conclusions: The results of this study provide support from a naturalistic, longitudinal clinical study for the hypothesis that reactivity to stress of some symptoms of schizophrenia may vary as a function of family history of the disorder.
