Interictal anxiety symptoms are reported in two-thirds of patients with epilepsy and represent an underrecognized and undertreated aspect of the disorder. Interictal anxiety is postulated to stem from both fear of seizure recurrence ("seizure phobia") and dispersed locus of control.In addition, anxiety and the most common forms of partial onset epilepsy are viewed to arise from dysfunction in a common neurobiological substrate-the amygdala and other structures within the limbic system.
Background on Pregabalin
Pregabalin (CI-1008,Lyrica) is a chemical analogue of the mammalian neurotransmitter gamma-aminobutyric acid (GABA),although it does not bind to or activates GABA receptors or inhibit GABA uptake. Pregabalin is an alpha-2-delta ligand that has analgesic, anxiolytic, and antiepileptic activity.
Antiepileptic drugs (AEDs) are commonly used for mood disorders including anxiety.Pregabalin (PGB) the most recently FDA-approved AED for add-on therapy for refractory partial seizures also has demonstrated efficacy in Generalized Anxiety Disorder. PGB binds to the alpha-2-delta subunit protein of voltage-gated calcium channels, and in animal models, has anxiolytic and anti-epileptic effects via pre-synaptic inhibition of the release of several excitatory neurotransmitters.

- Change in Beck Anxiety Score [ Time Frame: week 0 - week 6 ]The primary outcome variable will be the change in the Beck Anxiety Inventory (BAI) score as measured at the baseline and final visits.
- Change in BDI , NHS3 , STAI , NDDI-E and seizure frequency [ Time Frame: week 0 - week 6 ]The secondary outcome variables will be the change in the Beck Depression Inventory, change in National Hospital Seizure Severity Scale (NHS3) score, change in seizure frequency, change in Stait-Trait Anxiety Scale (STAI),and change in the National Disorders Depression Inventory for Epilepsy Screening Tool (NDDI-E) as measured at the baseline and final visits.
