Abstract

Sensori- and psychomotor abnormalities are an inherent part of schizophrenia-spectrum disorders (SSD) pathophysiology and linked to psychopathological symptoms as well as cognitive and global functioning. However, how these different symptom clusters simultaneously interact with each other is still unclear. Here, we examined 192 SSD patients (37.75 ± 12.15 years, 73 females). First, we investigated the cross-sectional prevalence and overlap of individual sensori- and psychomotor abnormalities. Second, we applied network analysis methods to simultaneously model the associations between Neurological Soft Signs (NSS), level of akathisia, parkinsonism symptoms, tardive dyskinesia (TD) and catatonia signs as well as cognition, psychopathology, global functioning and daily antipsychotic dose. The largest centralities were exhibited by NSS (0.90), catatonia signs (0.82) and global functioning (0.79). NSS showed strong partial correlations with cognition and parkinsonism symptoms (edge weight, ew = 0.409 and ew = 0.318, respectively). Catatonia signs showed strong connections with global functioning (ew = 0.333). In contrast, TD, akathisia and daily antipsychotic dose were weakly connected with other variables (e.g., largest ew=0.176 between TD and akathisia). In conclusion, NSS and cognition, parkinsonism symptoms and NSS as well as catatonia signs and global functioning seem to be preferentially connected in SSD. The daily medication had little influence on sensori- and psychomotor abnormalities, indicating that they are features of core SSD pathophysiology. Future studies should incorporate these relationships to enhance the understanding of SSD.
