Twin studies of brain structure and cognition in schizophrenia

Publication date: Available online 13 December 2019Source: Neuroscience &Biobehavioral ReviewsAuthor(s): Bianca Besteher, Paolo Brambilla, Igor NenadićAbstractTwin studies in schizophrenia have been crucial in establishing estimates for the heritability and thus providing evidence for a genetic component in this disorder. Recent years have seen the application of the twin study paradigm to both putative intermediate phenotypes and biomarkers of disease as well as a diversification of its use in schizophrenia research. This review addressed studies of brain structure (T1 morphometry) and cognition in schizophrenia using twin study designs. We review major findings such as the overlap of genetic variance between schizophrenia and cognition as a model for the emergence of psychopathology. The use of novel hybrid models integrating molecular genetic risk markers, as well as the use of twin studies in epigenetics might prove to significantly enhance schizophrenia research in the post-GWAS era.

CONCLUSIONS: These findings suggest that careful clinical history taking to document specific neurodevelopmental features may be informative in screening for individuals with schizophrenia who are at higher risk of carrying known SCZ-associated CNVs. Identification of genomic disorders in these individuals is likely to have clinical benefits similar to those demonstrated for other neurodevelopmental disorders.

We present the case of a 74-year-old man, with a history of residual schizophrenia, who underwent abdominal-pelvic CT with intravenous contrast, due to abdominal acute pain, that showed a stenosis at the origin of the celiac trunk and a large aneurysm of the hepatic artery, secondary to a mediam arcuate ligament syndrome, of the diaphragm was observed.

ConclusionsOur results indicate the prevalence of multiple comorbidities varies across the lifespan in DS, and in adults, rates for psychiatric comorbidities show different patterns for males and females relative to expected population rates. Further, most health comorbidities are not associated with poorer cognitive outcomes in DS, apart from autism and epilepsy. It is essential for clinicians to consider such differences to provide appropriate care and treatment for those with DS and to provide prognostic information relating to cognitive outcomes in those with comorbidities.

In this study, we analyzed the concentration of OPN, levels of cytokines associated with T-helper subtypes: interferon gamma (IFNy) for Th1, interleukin (IL)-10 for Th2, IL-8 for Th17, and neutrophil-to-lymphocyte ratio (NLR) in 22 patients with schizophrenia assessed for the intensity of their symptoms by the Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression scale (CGI) scores. Serum OPN, IFNy, IL-10, and IL-8 concentrations were measured by ELISA kits and NLR was calculated from blood count. We found significant correlation between the level of OPN and PANSS-total and PANSS-general scores. IFNy ...
