The presence and clinical implications of depression in a community population of adults with epilepsy.
Depression is the most common psychiatric comorbidity in epilepsy, but clinical and other factors associated with this observation and their impact on detection and management of depression in people with epilepsy are poorly understood. This study used a community-based postal questionnaire of primary care-identified people with epilepsy. We were therefore able to explore depression in a nonspecialist care-identified population. Clinical and demographic associative factors were examined. The dependent variable was depression, as defined by a score of 11 or greater on the Hospital Anxiety and Depression Scale (HADS). The prevalence of depression in our sample (n = 499) was found to be 11.2% (95% CI: 8.3-13.7%). Depression was most strongly associated with unemployment. It was also associated with having had a recent seizure and complaints of side effects of antiepileptic medications. Depression was not associated with gender, marital status, or monotherapy or polytherapy antiepileptic medication. The prevalence of depression in epilepsy is greater than in the general population, with no associated female preponderance. Our findings underline important variations in the associative features between depression in the general population and in people with epilepsy, with particular implications for management of this comorbidity.
