What is an EEG?

An electroencephalogram (EEG) is a diagnostic test that can evaluate the electrical impulses occurring in your brain. These impulses are what your cells use to communicate with each other, influencing your movements and biological functions.

An EEG monitors and records patterns of brain wave activity using electrodes attached to your scalp. The electrodes are attached to wires that connect to a computer and capture electrical brain activity. This is data can be reviewed to identify abnormal activity patterns.

Why do I need an EEG?

An EEG is an effective diagnostic test for a variety of neurological conditions or disorders. Common conditions an EEG can detect and monitor include:

• Seizures
• Epilepsy
• Fainting
• Brain tumors
• Sleep disorders
• Memory problems

What happens during an EEG?

An EEG is a noninvasive, painless procedure that is safe for people of all ages. To ensure the most accurate results, avoid the use of any hair products on your test day.

Your provider may advise you to stop certain medications in advance of your appointment. You should avoid eating or drinking for at least eight hours before your EEG.

During the test, your provider attaches several electrodes on your scalp in different locations. When the electrical impulses move through the electrodes, you won’t feel any abnormal sensations or pain.

You may be asked to breath quickly (hyperventilate) to help provoke seizure activity. Photic stimulation is also used which involves rhythmic flashing lights at various frequencies, to provoke seizure activity.

Depending on the reason for your test, it can take up to 60 minutes to achieve the necessary results. Once the test is complete, you can expect to go home and get back to your usual activities.

Our office utilizes only certified EEG technicians to ensure a high quality diagnostic test.

How are the EEG results determined?

Dr. Garza has completed a fellowship in Neurophysiology specializing in the reading and interpretation of EEGs. As an experienced neurologist, Dr. Garza can determine if there are any abnormalities in your results after a careful review of the brain wave patterns indicated by the test.
