The Epilepsy Program offers routine EEG screening and monitoring

  • Video-EEG

We perform out-patient routine and long-term video-EEG recordings using up-to-dated equipment. Modern machines provide precise diagnosis of different epilepsy syndromes. 

  • Long-term video-EEG monitoring 

We perform inpatient evaluation and treatment for patients with severe epilepsy or other uncontrolled seizures in Epilepsy Monitoring Unit (photo). Patients with seizures that are not responding to medication may require specialized evaluation and treatment. Long-term monitoring lasting 24 - 96 hours is done under close supervision of trained personnel. 
Patients are usually referred for inpatient monitoring

  • To determine the type of seizures they are having, and if they are epileptic seizures
  • To explore whether there are surgical options, or to learn more about what is causing a patient՚s seizures prior to surgery
  • To make medication changes in the safest possible environment

We also evaluate and treat patients suspected of having non-epileptic seizures or pseudo seizures, new onset seizure disorder, cardiac episodes etc.
What to expect during your stay 
What to expect during your stay 

  • Electrodes will be attached to the scalp with adhesive, so hair must be clean and free of products.
  • The adhesive used will be fairly strong to allow patients to be able to get out of bed if needed without the electrodes being displaced.
  • Patients may be asked to stay awake, either to trigger a seizure or increase the likelihood of a seizure occurring.
  • Patients must stay in bed during testing, both for safety and to allow the seizure to be captured on video.
  • Before or during hospitalization we may decrease the dose of anti-seizure drugs to increase probability of seizures /the patient will be asked to sign consent form/ 
  • Our rooms have accommodation for family members or other care partners to stay with you. They can also be an asset to your treatment by providing additional information about your seizures to the medical staff.

Preparing for your stay

  • Hair should be clean, without styling products, hairspray, braids or hair extensions to allow the electrodes to stick to the scalp.
  • Patients can wear their own clothes in the unit, but all shirts must be button-down or zip-front.
  • Patients will have an IV or catheter so medications can be given quickly and efficiently in case of emergency.
  • Cranial US (ultrasound)

A cranial ultrasound examination produces images of the brain and the cerebrospinal fluid. Since ultrasound waves do not pass through bone easily, this exam is most commonly performed on infants, whose skulls have not completely formed. The gaps between those skull bones provide a "window," allowing the ultrasound beam to freely pass into and back from the brain. The ultrasound probe and some gel are placed on the outside of the head in one of those regions without bone. 
In infants, head ultrasound is used to:

  • evaluate for hydrocephalus, or an enlargement of the ventricles, a condition that can have a number of causes.
  • detect bleeding within the brain tissue or the ventricles. 
  • assess whether there is damage to the white matter brain tissue surrounding the edges of the ventricles, a condition known as periventricular leukomalacia (PVL).
  • evaluate for congenital abnormalities.
  • locate the site of an infection or tumor.
  • Cranial Computed Tomography (CT) 

A cranial CT scan is a diagnostic tool used to create detailed pictures of features inside your head, such as your skull, brain, paranasal sinuses, ventricles, and eye sockets. It usually takes only about 15 minutes to complete scan. Thus, it is usually possible to perform it without anesthesia. Often, images are first taken without contrast, and then again with contrast. 
Reasons for a cranial CT scan
CT can help diagnose a range of conditions, including:

  • abnormalities of the bones of your skull
  • arteriovenous malformation, or abnormal blood vessels
  • atrophy of brain tissue
  • birth defects
  • brain aneurysm
  • hemorrhage, or bleeding, in your brain
  • hydrocephalus, or fluid buildup in your skull
  • nfections or swelling
  • injuries to your head, face, or skull
  • stroke
  • tumors

We closely collaborate with other institutions for Magnetic Resonance Imaging of the spine and brain.
