Epilepsy Test

The epilepsy EEG test or the "Electroencephalogram" is one of the main diagnostic tools used by medical professionals when it comes to confirming this particular condition. The goal of this particular test is to monitor the electrical based signals that occur within the brain and record the results of those signals so that they may be evaluated by a medical professional.

The test is typically painless for the individual that has to have it performed. Since the brain produces signals that are electrical based, a medical doctor will place electrodes on various locations of the head. These are small discs that are composed of metal. The metal helps to interpret the signals into a reading on the machine. This is how the epilepsy EEG test is read. 

Preparation 

If you have been asked to participate in the EEG epilepsy test, it is important to consider the instructions given to you by your doctor. Typically, they will inform you of the steps that can be taken to prepare for the examination. The first thing that you will want to do is to ensure that your doctor knows and understands what medications that you take on a regular basis.

You should inform the doctor of over-the-counter medications, prescription medications, and even supplements that you take regularly. You will need to wash your hair and your skin prior to taking the EEG epilepsy test. It is important to avoid using chemicals in the hair or on the skin prior to arriving for the test. Many of these substances contain metals and other substances that may alter the results of the test. 

The EEG Test 

When you are given the EEG test, you will be asked to lie on an examination table. The medical professional that is working to prepare you for the test will apply a type of adhesive to the electrodes that will be placed on your head. In a typical test, approximately fifteen to twenty of these electrodes are used so that an accurate reading may be obtained.

Once the adhesive has been placed on the head, the testing will begin. There is no need to worry about pain. Despite the fact that electrical signals are picked up by the electrodes, there is no electricity emitted from the electrodes that are used during the test. 

In most EEG epilepsy tests, you will likely be asked to open and shut your eyes. There are other commands that may be issued as well. These may include watching an assortment of lights that are flashing or closing your eyes while lights flash before your eyes. In addition to this, it is common to hear the medical professional to tell you to breathe in various ways.

The medical professional evaluating the test will analyze the patterns of the brain waves produced once the test is concluded. It is then that they will be able to identify an increase in electrical activity or if there are seizures possibly occurring. In nine of ten epilepsy cases, doctors are able to diagnose the condition using the epilepsy EEG test.
