Major depression, anxiety disorder and suicidality in epilepsy: What should neurologists do?

Abstract

Four to five patients with epilepsy (PWE) can suffer from Major Depressive episodes (MDE). Comorbid anxiety disorders (AD) frequently occur together with MDE. Failure to treat MDE can negatively affect several aspects of their life as well as the management of the epilepsy. Often, suicidal ideation is among its symptoms, which need to be addressed without delay to prevent suicidal attempts or a completed suicide. Unfortunately, access to health care professionals is very limited and, in many communities, non-existent. Accordingly, it falls upon the treating neurologist to begin a pharmacologic trial with psychotropic drugs. The purpose of this manuscript is to provide neurologists with very useful strategies on how to screen and identify MDEs with and without AD in the outpatient clinic and how to select the appropiate psychotropic drugs. Using an illustrative case, we discuss its differential diagnosis, particularly the recognition of iatrogenic episodes, and demonstrate the selection and mode of use of commonly used antidepressant in PWE. Finally, we provide a guide on how the neurologist can assess the suicidal risk of a patient that endorses suicidal ideation and the steps that need to be taken to minimize the risk of suicidal behavior.
