Epilepsy Monitoring Unit EMU

Why are patients referred to an Epilepsy Monitoring Unit (EMU)?

A person might be referred to an Epilepsy Center or
Epilepsy Monitoring Unit because:

  • Seizure events occurring for unknown reasons
  • Failure of standard treatments
  • New or unusual events  
  • Safety during medication withdraw
  • Evaluation for epilepsy surgery

The Epilepsy Monitoring Units at Saint Thomas West Hospital and Saint Thomas Rutherford Hospital are modern inpatient units designed to evaluate, diagnose, and treat epilepsy. They are overseen by board certified neurologists trained in epilepsy and equipped with digital long term video EEG monitoring systems for 24-hour correlation of patients’ electrical brain activity and symptoms.


Contact the Neurodiagnostic Lab by calling 615-222-6278 or 615-222-6298.

How should I prepare for a stay in an Epilepsy Monitoring Unit?
