Transdiagnostic types of formal thought disorder and their association with gray matter brain structure: a model-based cluster analytic approach.

ABSTRACT: Formal thought disorder (FTD) is a complex syndrome affecting language and thought processes in psychotic and affective disorders. Clustering (i.e., identification of data-driven clinical subtypes) establishes latent (sub-) structures into psychopathological syndromes. A latent profile analysis (LPA) of FTD symptoms was conducted in 1 032 patients diagnosed with Schizophrenia-Spectrum-Disorders (n = 107), Major Depressive (n = 800), and Bipolar Disorder (n = 125). Clusters were compared for cognition and psychopathology. Associations with gray matter volume (GMV) and cortical surface (gyrification, cortical complexity, sucal depth) were explored using T1-weighted MRI data, analyzed with CAT12. Robustness-analyses in an age- and sex-matched subsample (n = 321) with the same n for each diagn
