EEG

What is an EEG?

An EEG, or electroencephalogram, is a diagnostic tool that monitors and records the electrical activity in your brain. Your brain cells use electrical impulses to send messages both to other brain cells and throughout your body. 

An EEG shows the electrical activity, so Dr. Elkayam can look for abnormal activity and patterns. It’s a useful tool to diagnose brain disorders and the effects of head injuries. EEGs are noninvasive, safe, and painless. The test doesn’t include any stimuli such as flashing lights or sounds. 

Why would I need an EEG?

Dr. Elkayam uses EEGs to diagnose conditions, including:

• Seizures
• Concussions and head injuries
• Encephalitis (brain inflammation)
• Encephalopathy (a brain dysfunction disease)
• Memory problems
• Sleep disorders
• Brain tumors
• Stroke
• Dementia 

If you’re concerned about your brain health and are having symptoms of seizures, dementia, or sleep disorders, call Dr. Elkayam to schedule an assessment. The more quickly you get a diagnosis and start treatment, the better your chances are of avoiding disruptive health problems. 

How should I prepare for an EEG?

You have a consultation with Dr. Elkayam before your EEG, and he gives you personalized instructions on preparing for your procedure. In general, you should wash your hair the night before your appointment and not put any styling products in your hair. You should avoid caffeine for at least eight hours before your test. Dr. Elkayam provides instructions on whether you should take any medications or adjust your sleep routine before your test. 

What happens during an EEG?

When you have your EEG, a technician attaches several electrodes to your scalp. The electrodes pick up electrical activity in your brain and transmit it to a computer, which measures and monitors your brain waves.

An EEG usually lasts for 30-60 minutes. You sit in a reclining chair or lie on a treatment table. Your technician may give you instructions to open or close your eyes or breathe deeply. If they’re testing for seizures, the technician may ask you to look at a flashing light or image. All of the EEG technicians at Frontier Neurology are fully trained and can take immediate action to protect your safety on the rare occasion of the test triggering a seizure. 

When your EEG is complete, your technician removes the electrodes. Dr. Elkayam might review your results immediately, or you might have a follow-up appointment to discuss your EEG.
