To study the risk of developing unprovoked seizures among MSers and systemic lupus erythematosus (SLE), we used 1885 new onset seizure cases, 15,080 controls and defined exposure as a hospital discharge diagnosis of MS or SLE. The odds ratio with 95% confidence interval was 3.7 (CI 1.2-11.0) for MS and 8.0 (2.2-30.0) for SLE, suggesting an increased risk of unprovoked seizures in patients with both these diagnoses.
