Brain Network Activation Analysis in Epilepsy

Study Overview
=================
Brief Summary
-----------------
This is a prospective study investigating the utility of Brain Network Activation (BNA) analysis in patients with epilepsy.

Detailed Description
-----------------
BNA technology is based on a network model to depict functional connectivity. The descriptive network model approach provides insights regarding inter-connectivity of brain networks and can describe the temporal-spatial brain activation patterns applied to various types of data-sets including EEG, MEG and fMRI. In this study it is proposed that synchronization in brain activity may be disrupted in patients who experience frequent seizures and may correspond to functional impairments (e.g., memory, processing speed). As such, BNA analysis may provide additional data that complement current functional assessments, inform clinical assessment and management of epilepsy, and identify subgroups of patients that might be at risk for poor treatment outcomes.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Assess the BNA database for Epilepsy population and healthy controls. | Functional networks of brain activity in Epilepsy (Right and Left lobe) and healthy control individuals measured using analysis of EEG Event Related Potential (ERP) data. Clinical assessments battery will be utilized in order to examine different sets of BNA database for Epilepsy pathology and healthy controls. | Epilepsy subjects will perform the BNA testing at baseline prior to change in medication if applicable and 3-10 days following change in medication when applicable. |
