EEG and Ambulatory Video EEG

EEG and Ambulatory Video EEG

At San Jose Pacific Neurology Center is a one-stop solution for all your EEG needs. Our expertise and capabilities allow us to provide routine EEG and Ambulatory Video EEG.

Routine EEG

An electroencephalogram (EEG) is a safe and painless test that measures and records the electrical activity of your brain by using sensors (electrodes) attached to your head and connected by wires to a computer. An EEG is one of the important tests used to diagnose neurological issues, especially epilepsy. Electrodes, made of small and flat metal discs, are attached to the scalp with wires connected to a computer. The electrodes detects the brain’s electrical impulses and send signals to a computer, where the results are recorded. 

This test is performed to see how the different parts of the brain function. EEGs also help caregivers learn about sleeping problems, brain injury, brain tumors, and many other problems. The machine records a graph of your brain waves. No electricity is transferred to your brain. This is performed by a specially trained technician.

EEG is also used to monitor activity during a brain surgery, as well as detect brain activity on a comatose patient.

An EEG is utilized to detect abnormalities in the electrical activity of the brain associated with certain brain disorders. The results of EEG are used to confirm or rule out diagnosis of specific conditions, such as:

  • Seizures and epileptic disorders

  • Head or brain injury
  • Enciphalitis (inflammation of the brain)

  • Encephalopathy (abnormal brain function)

  • Amnesia (memory problem)

  • Dementia

  • Sleep disorders

  • Stroke

  • Brain tumor

Ambulatory Video EEG

Ambulatory Video EEG is monitoring uses advance technology that allows prolonged electroencephalographic (EEG) recording in the home setting. Its ability to record continuously for up to 72 hours increases the chance of recording an ictal event or interictal epileptiform discharges. The video camera monitors physical and subjective symptoms such as seizures, fainting, twitching, twitching, shaking, tingling, and more. This gives further insight in relation to the brain activity captured by the EEG. Our highly-experienced and board-certified neurologists can use the video and EEG information to help determine correlation between the symptoms and brain activity.

Continuous Ambulatory Video EEG recording is a standard of care in establishing an accurate diagnosis in epilepsy. The technicians will attach about 22 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 study which is typically from 24 hours to 72 hours. General instructions are the same sa above for a routine EEG.

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.

Ambulatory Video EEG is lightweight and tamper proof for both pediatric and adult needs. It has an easy access to event button, which allows patient to mark an occurrence if/when experiencing symptoms or spells.

  • Continuous recording for up to 72 hours

  • Captures physical symptoms or spells, in addition to the EEG recording

  • Flexible and convenient for patients for in-home monitoring

  • Gives patients the ability to mark an occurrence if/when symptoms manifest
  • Allows for overnight monitoring
