![]() ![]() Otherwise, no specific follow-up is necessary. Follow-UpĬontact your doctor within a few days to find out the results of your EEG. Once the EEG is finished, the electrodes are removed and any excess EEG gel or paste is cleaned away. In some people, EEG recording continues as you fall asleep. As your EEG continues, you will need to open and close your eyes, breathe quickly and deeply, and look at a flashing light. A special gel or paste helps the electrodes pick up your brain waves more efficiently.Īs the electrodes detect your brain waves and feed them into the EEG machine, several wavy lines (your brain wave patterns) appear on the polygraph's graph paper. Your scalp will not be shaved, but the area under the electrodes will be cleaned to remove any excess oils from your scalp. You will sit or lie comfortably while a technician attaches a number of small electrodes to your head. If necessary, the doctor will give specific instructions about how and when to limit sleep before the EEG. ![]() This makes it more likely that seizures or other abnormalities will occur. However, in some people, an EEG gives better results if the recording is obtained after a period of no sleep (sleep deprivation). In most cases, no special preparation is necessary. Occasionally, an EEG may be used to confirm brain death, for example, in someone on life support who is in a deep coma. An EEG can help to diagnose certain types of brain illnesses that cause worsening mental impairment and brain dysfunction, such as encephalopathy caused by severe liver or kidney disease. It also may be used to evaluate someone with confusion, head injuries or other conditions that may be caused by an abnormality in the brain. What It's Used Forĭoctors most often order an EEG to help diagnose a seizure disorder or monitor effectiveness of anti-seizure medicine in people with epilepsy. Lightweight EEG devices allow people to walk around and perform normal daily activities while the devices detect and record brain waves over longer periods of time. A basic EEG takes about 45 minutes, with a range of 30 minutes to 90 minutes. ![]() In some cases, the waves are transmitted to a computer screen. A polygraph machine records the brain waves. Metal electrodes attached to the skin on the outside of the head transform electrical activity into patterns, commonly called brain waves.
