Background Psychiatric comorbidities are common in patients with *** for the co-occurrence of psychiatric conditions and epilepsy remain poorly *** We aimed to triangulate the relationship between epilepsy and psychiatric conditions to determine the extent and possible origins of these *** Using nationwide Swedish health registries,we quantified the lifetime prevalence of psychiatric disorders in patients with *** then used summarydata from genome-wide association studies to investigate whether the identified observational associations could be attributed to a shared underlying genetic aetiology using cross-trait linkage disequilibrium score ***,we assessed the potential bidirectional relationships using two-sample Mendelian *** In a cohort of 7628495 individuals,we found that almost half of the 94435 individuals diagnosed with epilepsy were also diagnosed with a psychiatric condition in their lifetime(adjusted lifetime prevalence,44.09%;95%confidence interval(Cl)43.78%to 44.39%).We found evidence for a genetic correlation between epilepsy and some neurodevelopmental and psychiatric *** example,we observed a genetic correlation between epilepsy and attention-deficit/hyperactivity disorder(r,=0.18,95%Cl 0.09 to 0.27,p<0.001)—a correlation that was more pronounced in focal epilepsy(r=0.23,95%CI 0.09 to 0.36,p<0.001).Findings from Mendelian randomisation using common genetic variants did not support bidirectional effects between epilepsy and neurodevelopmental or psychiatric *** Psychiatric comorbidities are common in patients with *** correlations may partially explain some comorbidities;however,there is little evidence of a bidirectional relationship between the genetic liability of epilepsy and psychiatric *** findings highlight the need to understand the role of environmental factors or rare genetic variations in the origins of psy
