Abstract:
Anxiety disorders are frequent, though probably underdiagnosed, comorbidities in epilepsy. Epilepsy and anxiety may share common neurobiological correlates as shown in animal models and suggested by studies demonstrating anxiety disorders before the manifestation of epilepsy. Comorbid anxiety disorders have a major impact on the affected patients' quality of life and may increase the risk for suicidality. Successful treatment of the epilepsy may alleviate anxiety symptoms. Treatment of anxiety is based on selective serotonin reuptake inhibitors, benzodiazepines (although only as second-line choices), and psychotherapy. Specific AEDs (especially pregabalin) have been shown to have anxiolytic properties. This paper is aimed at reviewing anxiety disorders in patients with epilepsy discussing current scientific evidence about pathophysiology, clinical aspects, and treatment strategies.

Anxiolytic Drugs: Overview
Primary Types of Anxiolytic Drugs
1. Benzodiazepines:
Benzodiazepines bind to the GABA-A receptor in the brain, enhancing GABA's interaction. This action reduces neurotransmission, effectively blocking anxiety-associated limbic...
