The inpatient epilepsy service is available for the presurgical evaluation of medically intractable epilepsy, as well as the characterization of spells or seizure type using long-term video-EEG monitoring. Residents and fellows participate in the management and care of these patients.
In addition to the video-EEG monitoring, presurgical (Phase I) work-ups typically include:
Should invasive (Phase II) monitoring be necessary, depth electrodes, subdural strip or grid array electrodes, or peg electrodes are utilized as needed.
Surgical treatment includes lobectomy, lesionectomy, corticectomy, hemi-spherectomy, or corpus callosotomy.
An epilepsy conference is held twice a week for data presentation and to recommend site and type of surgery or additional invasive monitoring using intracranial electrodes, if indicated.

There is a separate Comprehensive Epilepsy Clinic at Duke that meets weekly and includes staff epileptologist, clinical neurophysiology fellows, and the resident on the EEG rotation. Senior residents may also request an elective rotation by arrangement.
There is also an Epilepsy Clinic at the Durham VA Hospital that meets twice a month, alternating weeks with Duke Epilepsy Clinic. This clinic is staffed by epileptologists, clinical neurophysiology fellows, and the Duke residents on rotation at the VA Hospital. New patients at both clinics are evaluated for medical and surgical therapy for intractable seizures, as well as characterization of spells which may be epileptic or nonepileptic in origin.
The Sleep Disorders Center at Duke is comprised of staff neurologists, psychiatrists, clinical psychologists, and clinical neurophysiology fellows.
Outpatient clinics are held twice a week and evaluate patients with all forms of sleep disorders, including dyssomnias (e.g. obstructive sleep apnea, narcolepsy, etc.), para-somnias (e.g. sleep terrors, REM sleep behavior disorder, etc.), and sleep disorders associated with medical or psychological disorders (e.g. neurodegenerative diseases, substance abuse, depression, etc.). Senior residents may request an elective rotation by arrangement.
Sleep laboratory evaluations are carried out via traditional in-lab overnight polysomnography or outpatient ambulatory cassette recording. In-lab recordings focus primarily on evaluation of nocturnal respiratory dysrhythmias and measure EEG, axial and limb EMG, electro-oculogram (EOG), ECG, oxygen saturation, airflow and respiratory effort, and video monitoring. Ambulatory studies focus primarily on sleep stage (EEG, EMG, EOG), as well as leg movements and single measure of airflow, and predominately evaluate patients with insomnia. Multiple sleep latency testing and vigilance testing are also performed at the Duke Sleep Disorders Center.
Electroencephalography is performed at Duke University Hospital and is available on an emergency basis. EEG's are also done at the Durham VA on weekdays. Evoked potentials are performed at Duke North Hospital and also used for operative monitoring (BAER, SSEP). Residents, fellows, and attendings participate in the performance and interpretation of all studies. There were 1881 EEG's, 616 evoked potentials, and 712 overnight sleep studies done in 1999 at Duke. There were 631 EEG lab studies at the Durham VA Hospital. Central neurophysiology/epilepsy fellowships are available for one and two year slots. Research opportunities are also available.
