The current study investigated characteristics of the deep vascular layer in SZ. We included 28 individuals with a diagnosis of SZ or schizoaffective disorder, and 37 HCs. Optical coherence tomography angiography (OCTA) data was collected to measure deep retinal layer perfusion density, skeletonized vessel density, vessel diameter index, and fractal dimension. We conducted between-group comparisons to examine differences in these OCTA variables between SZ and HC groups. A trend analysis was conducted to determine if differences reflected a linear trend according to age and illness length, and Spearman correlations were conducted to determine associations between deep and superficial layer density. Individuals with SZ demonstrated significantly lower bilateral perfusion density and vessel diameter index, as well as lower left eye skeletonized vessel density and fractal dimension. There was a significant linear trend in the data indicating that individuals with chronic SZ demonstrated the lowest OCTA values, followed by individuals within two years of their first episode of psychosis who did not differ from older controls, followed by younger controls, who demonstrated the highest values in at least one eye. Lower density values in the deep retinal layer were also significantly associated with lower density values in the superficial layer.

Robert Spitzer and the DSM-III project hoped to rescue psychiatry by fixing its diagnoses. However, their choices regarding the schizophrenia diagnosis perhaps hampered psychosis research for 40 years. The defining characteristics of psychosis are perceptions, thoughts, and actions that do not comport with socially shared experience. For Kraepelin and Bleuler, the core features of a schizophrenia-like psychosis syndrome were disturbances of affect, self, and volition. John Wing and the International Pilot Study of Schizophrenia (IPSS) favored the theory of Kurt Schneider and his symptoms of first-rank importance for diagnosing schizophrenia. They reconceptualized schizophrenia as a reality distortion diagnosis. Will Carpenter and John Strauss, using IPSS data, showed that schizophrenia was most like an affect-self-volition disturbance syndrome and that depending on reality distortions for a schizophrenia diagnosis was incompatible with the evidence. Nevertheless, schizophrenia in DSM-III and DSM-IV was championed by John Wing and embraced by the DSM framers. Outcomes from the Bipolar-Schizophrenia Network for Intermediate Phenotypes (B-SNIP) are consistent with Carpenter and Strauss's concern that switching from a Kraepelin-Bleuler core to reality distortion was an error. B-SNIP found, replicated, cross- and externally validated neurobiologically distinctive subgroups called psychosis Biotypes. The main clinical characteristics differentiating the Biotypes are thought disturbances, lack of spontaneous speech, and low involvement in social and occupational activities.

This SNP was associated with OCD in dominant model (TT+TC versus CC) only in un-adjusted analysis (OR (95 % CI) = 0.52 (0.31–0.88), <em>P</em> value = 0.015). Finally, this SNP was associated with OCD in over-dominant model (CC+TT versus TC) in both un-adjusted and adjusted by sex analyses (OR (95 % CI) = 2.38 (1.33–4.25), <em>P</em> value = 0.003 and OR (95 % CI) = 2.78 (1.31–5.89), <em>P</em> value = 0.008, respectively). The current study shows possible impact of rs920778 on risk of OCD in Iranian population.</p></div>","PeriodicalId":52767,"journal":{"name":"Biomarkers in Neuropsychiatry","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666144623000199/pdfft?md5=afb5fe3a6c26e1882d00bb5d11336c23&pid=1-s2.0-S2666144623000199-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134656614","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
