    ABSTRACT: Although it is undisputable that patients with severe mental illness have impaired ability to work, the extent of this is unclear. This is a nation-wide, cross-sectional survey of patients who have been hospitalized with severe mental illness earning minimum wage or above. Data from the Israeli Psychiatric Hospitalization Case Registry were linked with nation-wide data from the National Insurance Institute (the equivalent of US Social Security) on personal income. Hospitalization data were obtained on all consecutive admissions to any psychiatric hospital in the country between 1990-2008 with a diagnosis of schizophrenia, other nonaffective psychotic disorders, or bipolar disorder (N = 35 673). Earning minimum wage or more was defined as earning at least 1000 USD/month, which was equivalent to minimum wage in Israel in December 2010. The percentages of patients with only 1 admission who were earning minimum wage or above in December 2010 were as follows: 10.6% of patients with a diagnosis of schizophrenia; 21.6% of patients with a diagnosis of nonaffective psychotic disorders; and 24.2% of patients with bipolar disorder. The percentages of patients with multiple admissions who were earning minimum wage or above were as follows: 5.8% of patients with schizophrenia; 11.2% of patients with nonaffective psychotic disorders; and 19.9% of patients with bipolar disorder. Despite potential confounders, the results indicate that patients with schizophrenia, nonaffective psychotic disorders, or bipolar disorder have a poor employment outcome, even if they have only been admitted once. These results emphasize the importance of improving interventions to re-integrate these individuals into the work force. © The Author 2015.

    ABSTRACT: Several laboratories, including ours, have reported an overrepresentation of craniofacial (CF) anomalies in schizophrenia (SZ). How might this dysmorphology arise in a brain-based disorder? Because the brain and face derive from shared embryologic primordia and morphogenetic forces, maldevelopmental processes may result in both CF and brain dysmorphology. Our approach is 2-pronged. First, we have employed, for the first time in the study of psychiatric disorders, objective measures of CF morphology that utilize an extensive normative database, permitting computation of standardized scores for each subject. Second, we have rendered these findings biologically interpretable by adopting principles of embryology in the analysis of dysmorphology. Dependent measures in this investigation focused on derivatives of specific embryonic primordia and were contrasted among probands with psychotic disorders, their first-degree relatives, and normal controls (NC). Subject groups included patients with a diagnosis of SZ (N = 39) or bipolar (BP) disorder with psychotic features (N = 32), their clinically unaffected relatives (N = 82 and N = 41, respectively), and NC (N = 95) subjects. Anomalies involving derivatives of frontonasal and mandibular embryonic primordia showed a clear association with psychotic illness, as well as familial aggregation in relatives in both diagnostic groups. In contrast, one class of CF anomalies emerged only among SZ probands and their first-degree relatives: dysmorphology arising along the junction of the frontonasal and maxillary prominence derivatives, manifested as marked asymmetries. This class was not overrepresented among the BP patients nor among their relatives, indicating that this dysmorphology appears to be specific to SZ and not a generalized feature of psychosis. We discuss these findings in light of embryologic models that relate brain regions to specific CF areas. © The Author 2015.

    ABSTRACT: * The first and second author contributed equally to this work Background: Schizophrenia is a multi-faceted mental disorder characterized by cognitive, perceptual and affective symptom dimensions. This heterogeneity at the phenomenological level may be subserved by complex and heterogeneous patterns of structural abnormalities. Thus, delineating such patterns may improve the insight into the variability of disease and facilitate future MRI-based diagnosis. Methods: We aimed to identify structurally complex signatures that directly differentiate patients with predominantly negative (pNEG), positive (pPOS) and disorganized (pDIS) symptoms using Optimally-Discriminative Voxel-Based Analysis (ODVBA). ODVBA is a new analytical framework for group analysis, which showed to have superior sensitivity and specificity over conventional voxel-based morphometric approaches, thus facilitating the identification of subtle neuroanatomical signatures delineating different subgroups. Results: pPOS were characterized by pronounced gray matter (GM) volume reductions in the ventromedial prefrontal cortex (vmPFC), which herein is defined to include the orbitofrontal cortex, and in occipito-temporal GM and parts of the lingual gyrus. pNEG was found to have vmPFC reduction but to a lesser degree than pPOS and with a relative sparing of the more medial vmPFC regions, compared to pDIS; it also had significantly less cerebellar GM. pDIS showed relatively highest GM volume preservation among three subtypes. Conclusions: Although a common prefronto-perisylvian GM reduction pattern was present at the whole-group level, marked morphometric differences emerged between the three subgroups, including reduced cerebellar GM in pNEG, and reduced vmPFC and occipito-temporal GM in pPOS. Besides deepening our insight into the neurobiological underpinnings of clinical heterogeneity, these results also identify important imaging biomarkers that may aid patient stratification.

    ABSTRACT: People living in densely populated and socially disorganized areas have higher rates of psychiatric morbidity but the potential causal status of such factors is uncertain. We used nationwide Swedish longitudinal registry data to identify all children born 1967-1989 (n=2,361,585), including separate datasets for all cousins (n=1,715,059) and siblings (n=1,667,894). The nature of the associations between population density and neighborhood deprivation and individual risk for a schizophrenia diagnosis were investigated while adjusting for unobserved familial risk factors (through cousin and sibling-comparisons), and then compared with similar associations for depression. We generated familial pedigree structures using the Multi-Generation Registry and identified study participants with schizophrenia and depression using the National Patient Registry. Fixed-effects logistic regression models were used to study within-family estimates. Population density, measured as ln(population size/km^2), at age 15 predicted subsequent schizophrenia in the population (OR=1.10; 95% CI 1.09-1.11). Unobserved familial risk factors shared by cousins within extended families attenuated the association (1.06; 1.03-1.10) and the link disappeared entirely within nuclear families (1.02; 0.97-1.08). Similar results were found for neighborhood deprivation as predictor and for depression as outcome. Sensitivity tests demonstrated that timing and accumulation effects of the exposures (mean scores across birth, ages 1-5, 6-10 and 11- 15 years) did not alter the findings. Excess risks of psychiatric morbidity, particularly schizophrenia, in densely populated and socioeconomically deprived Swedish neighborhoods appear therefore to result primarily from unobserved familial selection factors. Previous studies may have overemphasized the etiological importance of these environmental factors.

    ABSTRACT: Recent studies suggest that people with schizophrenia (PSZ) have difficulty distributing their attention broadly. Other research suggests that PSZ have reduced working memory (WM) capacity. This study tested whether these findings reflect a common underlying deficit. We measured the ability to distribute attention by means of the Useful Field of View (UFOV) task, in which participants must distribute attention so that they can discriminate a foveal target and simultaneously localize a peripheral target. Participants included 50 PSZ and 52 healthy control subjects. We found that PSZ exhibited severe impairments in UFOV performance, that UFOV performance was highly correlated with WM capacity in PSZ (r = -.61), and that UFOV impairments could not be explained by either impaired low-level processing or a generalized deficit. These results suggest that a common mechanism explains deficits in the ability to distribute attention broadly, reduced WM capacity, and other aspects of impaired cognition in schizophrenia. We hypothesize that this mechanism may involve abnormal local circuit dynamics that cause a hyperfocusing of resources onto a small number of internal representations.
