Studies from Icahn School of Medicine at Mount Sinai Provide New Data on Schizotypal Personality Disorders (Aberrant effective connectivity during working memory performance in schizotypal personality disorder and schizophrenia: A spectrum...).

The article focuses on new research regarding Schizotypal Personality Disorder (SPD) and its relationship to schizophrenia, particularly in the context of working memory (WM) deficits and brain connectivity. Conducted by researchers at the Icahn School of Medicine at Mount Sinai, the study utilized dynamic causal modeling to analyze effective connectivity among brain regions during WM tasks in healthy controls, individuals with SPD, and schizophrenia patients. Findings indicate that while healthy individuals show a typical pattern of connectivity, those with schizophrenia exhibit an abnormal pattern, and individuals with SPD demonstrate an intermediate connectivity pattern. The research suggests that these connectivity differences may be linked to symptom severity in schizophrenia. [Extracted from the article]
