Cognitive dysfunction is the most common neuropsychiatric manifestation in systemic lupus erythematosus (SLE), yet the underlying structural MRI correlates of cognitive dysfunction remain unclear. We investigated cortical thickness differences among SLE patients and healthy controls, and among SLE patients stratified by cognitive impairment status. Results showed no cortical thickness differences between SLE patients and controls, yet SLE patients with cognitive impairment bilaterally showed reduced cortical thickness in a number of regions when compared to cognitively intact SLE patients. These results suggest that cognitive impairment, even in the absence of other neurological syndromes, may be associated with underlying structural brain alterations.
