EEG Q & A

What is an EEG?

EEGs monitor and evaluate the electrical activity in your brain. Your brain cells communicate with electrical impulses, and an EEG can show if any of those impulses are abnormal or absent.

The test is noninvasive and painless. Your neurologist at JKC Neurology Medical Group attaches small electrodes to your scalp that track your brain activity and transmit the details to a computer, where the information is recorded and stored for analysis.

Your neurologist may request that you wear an ambulatory EEG for a day or so at home to collect more data about your brain activity. 

Why would I need an EEG?

If you’ve had a seizure, head injury, or have symptoms that could indicate a brain abnormality, your doctor may order an EEG. EEGs can diagnose:

  • Epilepsy and other seizure disorders
  • Head injuries
  • Encephalitis
  • Tumors
  • Stroke
  • Dementia
  • Sleep disorders
  • Encephalopathy

Doctors also use EEGs to monitor activity during brain surgery or to check for signs of activity in patients who are in a coma or other vegetative state.

How should I prepare for my EEG?

Before your EEG, talk to your neurologist at JKC Neurology Medical Group about any medications you take, including vitamins and supplements. 

They’ll give you personalized advice on whether you need to stop taking anything for a day or so before your EEG. You should also avoid caffeine for at least 24 hours before your test.

If your doctor needs you to do anything else in advance of your EEG, they’ll give you specific instructions.

What happens during an EEG?

An EEG usually takes 30-60 minutes at the comfortable office of JKC Neurology Medical Group. You recline on a treatment bed or comfortable chair, and a technician places the electrodes onto your scalp. 

Depending on your symptoms, you may need to stay awake or sleep during the test. If necessary, your doctor can provide a mild sedative to help you relax and sleep.

When the EEG begins, the electrodes monitor and record the electrical activity in your brain. They send the information to a computer, which converts your brain activity into a visual pattern of lines. 

After your EEG you can go home and return to your regular activities. If you need a sedative for the test, you should arrange for a friend or family member to drive you home.

If your doctor provides an ambulatory EEG, the electrodes are attached to your scalp for a day or so at home. When you return the equipment, your doctor studies the data collected to check for abnormalities and other signs of irregular brain function.
