Go to the first floor of the East Pavilion and sign in at the Admitting Desk.

Description

Continuous Audio Visual EEG recording is a standard of care in establishing an accurate diagnosis in epilepsy. The technicians will attach about 25 electrodes to your scalp using a special adhesive. Each electrode is connected to a wire which eventually connects to a computer system. Your brain emits very weak electrical discharges which the electrodes are able to collect. During various activities, such as a seizure, the electrodes over the active areas receive more electrical stimulation than the other electrodes. Your doctor is able to study this information to help determine the area in the brain responsible for the seizures. These electrodes will remain attached for the entire duration of the hospital stay. To help seizures occur naturally so they can be studied, we often will remove medications during this testing.

Sometimes we will try to perform an injection during the seizure for an ictal SPECT scan which can be done after you recover from your seizure. This helps to localize seizure generating areas of the brain, and shows blood flow changes with seizures.

In addition to EEG monitoring, you will be monitored on an audio-video camera. Your image, along with simultaneous EEG recordings, is saved. When you have a seizure, the doctor will be able to review the EEG and see exactly how you responded. This will help determine the location of the seizures, and their severity.

Patient Instructions

You will be admitted to the hospital for approximately one week for evaluation of your seizures. During this time, we will be trying to record several of your seizure episodes. Additional testing may be done at this time as well.

Continue to take all prescribed medications until you have been admitted to the hospital. Your medication may be adjusted, reduced, or even temporarily stopped while you are hospitalized.

The car will be valet parked per calendar day for a fee of $12.00. To note, parking validation is not available. If you have further questions regarding parking, please contact (203) 688-2623.

You will be admitted to a specially equipped single room with a video camera at the foot of the bed. Electrodes will be glued to your scalp and left in place to allow for continuous EEG recording. Please be sure your hair is clean and free of gels and/or sprays. Please bring conditioner to help with removing the glue on your scalp from the electrodes.

Mobility within the room is restricted, due to the monitoring devices, and for patient safety. You will be limited to movement between the bed and a chair located next to the bed.
