Treatment of Comorbid Anxiety and Epilepsy
Abstract
Objective:
Anxiety is among the most common psychiatric illnesses, and it commonly co-occurs with epilepsy. This review of the existing literature on anxiety comorbid with epilepsy aims to generate new insights into strategies for assessment and treatment.
Methods:
The authors conducted a narrative literature review to select key publications that help clarify the phenomenology and management of comorbid anxiety and epilepsy.
Results:
Anxiety symptoms may be relevant even if the criteria for a diagnosis of an anxiety disorder are not met. Associating specific seizure types or seizure localization with anxiety symptoms remains difficult; however, the amygdala is a brain region commonly associated with seizure foci and panic or fear sensations. The hypothalamic-pituitary-adrenal axis may also be relevant for anxiety symptoms, particularly for the selection of treatments. Nonpharmacological treatment is appropriate for anxiety comorbid with epilepsy, particularly because relaxation techniques may reduce hypersympathetic states, which improve symptoms. Medication options include antidepressants and anticonvulsants that may have efficacy for anxiety symptoms. Benzodiazepines are a good choice to address this comorbid condition, although side effects may limit utility.
Conclusions:
Ultimately, there are numerous treatment options, and although there is a limited evidence base, quality of life may be improved with appropriate treatment for individuals experiencing comorbid anxiety and epilepsy.
