Goal for our patients
Hospitalization for seizure monitoring
Technology used to create patient’s treatment plan
Surgical options in Epilepsy
Future technology/management of Epilepsy
“No seizures, no side-effects”
70% of patients’ seizures are controlled by medications
Admission to Epilepsy Monitoring Unit for several days
Continuous EEG with audio and video monitoring
Seizure induction by discontinuing meds, sleep deprivation,
exercise, hyperventilation, and photic stimulation
Curry computer system
Can superimpose multiple images for increased
accuracy (called co-registration)
Example: EEG and MRI co-registration used to better
localize seizure-onset zone/circuits
WADA Testing- developed during World War II, used in North
America since the 1950’s
Cerebral language and memory representation of each
hemisphere
Barbiturate medication injected into Internal Carotid Artery to
test each brain hemisphere
Meds put that side of brain “to sleep” to allow testing of
language and memory on opposite side of brain
Functional MRI- “brain mapping” – newer technology, noninvasive, rapidly becoming more advanced, may eventually
replace Wada testing
SPECT and PET
Both used to help with seizure foci localization
SPECT (Single Photon Emission Computed Tomography) scan
◦ Examines blood flow
◦ Injection of radioisotope given during seizure to view increased
blood flow at seizure site
PET (Positron Emission Tomography) scan of Brain
◦ Examines glucose metabolism
◦ Performed “inter-ictally” or between seizures to view areas of
hypometabolism
Accepted treatment for medically refractory epilepsy since
the late 19th century
Numerous studies report seizure freedom at 53-84%
Usually need to continue AEDs for 1 year then taper
Promising new device created by Neuropace
Responsive NeuroStimulation (RNS) – effective in reducing
seizures by 50% in >50% of patients
Only effective in focal onset epilepsies, but can be effective
if 2 foci in a given patient
Vagus Nerve Stimulator – effective in reducing
seizures by 50% in >50% of patients
Good for both focal onset and primary generalized
epilepsies
Invasive procedure yielding high resolution information
Provides the most localized area of seizure activity
Allows mapping of language areas
Temporal lobectomy-most often removal of the anterior portion of temporal
lobe
Lesionectomy-removal of a seizure causing lesion in any part of the brain
Partial corpus callosotomy- corpus callosum severed to prevent seizure
spread through intrahemispheric pathways
Multiple subpial transections- small incisions to “interrupt” seizures
performed when seizures originate in brain areas that cannot be removed
Genomics-Personalized Medicine: Finding the right drug for
each patient through gene testing
◦ Only need saliva or blood to perform test
Deep Brain Stimulation-implanting electrodes into specific areas of
the brain, and then stimulating these areas with small regular
electrical impulses
Emfit Tonic-Clonic Seizure Monitor
SAMi Sleep Monitor
◦ Sounds alarm when an unusual movement is detected
during the night
◦ Audio video information from a remote infrared video
camera is sent to an app which can run on a smart phone
◦ Totally portable
Smart Watch and Embrace Seizure Watch
◦ Measures electrodermal activity and motions
