Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Patient has a clinical diagnosis of epilepsy requiring additional evaluation in an epilepsy monitoring unit (EMU).
• Patient likely requires an EMU evaluation for a period of at least 3 days.
• In the opinion of the Principal Investigator, the Patient is likely to have 3 - 5 seizures during the EMU stay.
• Patient is currently taking at least one antiepileptic medication.
• Patients must be 18 years or older and may be of either sex and of any race.
• Patient must be in good general health, fully ambulatory, and able to complete the physical aspects of testing requirements.
• Patient must be willing and able to complete informed consent and HIPAA authorization.
• Patient is diagnosed with epilepsy but may also experience pseudo seizures or psychogenic seizures.

You may not qualify if…

• Patients with severe psychiatric disease that in the investigator's judgment would prevent the patient's successful completion of the study.
• Patients experiencing status epileptic within the last 6 months.
• Patients with cardiovascular, respiratory, neuromuscular or gait disorders that in the investigator's judgment would cause unnecessary risk.
• Patients prescribed drugs specifically for a cardiac or autonomic disorder that in the investigator's opinion would affect heart rate response. Drugs with secondary cardiac or autonomic actions are allowed.
• Patients with cardiovascular arrhythmias or cardiac disease that would preclude the ability to detect intrinsic changes in heart rate due to exercise, stress, or seizure. This would include but not be limited to chronic atrial fibrillation and permanent cardiac pacemaker implantation.
• Patients currently dependent on alcohol or narcotic drugs as defined by DSM IV-R.
• Patients with a history of only psychogenic seizures or pseudo seizures.
• Women who are pregnant. Women of childbearing age must take a pregnancy test.
