Background: Patients with schizophrenia (SZ) exhibit frontotemporal atrophy accompanied by cognitive impairment. However, the relationship between CT-derived structural changes and cognitive deficits remains underexplored. This study aimed to evaluate the association between frontotemporal atrophy and cognitive performance using routine cranial CT. Methods: This retrospective cross-sectional case-control study included 120 patients with SZ and 100 healthy controls. Bifrontal ratio (BFR), frontal horn width (FHW), mean temporal horn width (THWₘean), sylvian fissure width (SFW), and frontotemporal atrophy index (FTAI) were measured. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA) and the Trail Making Test (TMT). Group comparisons, Spearman correlation, and multivariable regression analyses were performed. Results: = 0. 319). Conclusion: CT-derived frontotemporal atrophy was significantly associated with cognitive impairment in SZ. These findings suggest that CT-based structural measures may provide a clinically accessible approach for characterizing brain changes related to cognitive dysfunction.
