An electroencephalography (EEG) test is a non-invasive procedure that measures and records the electrical activity of the brain. It involves placing small sensors, called electrodes, on the scalp to detect and monitor brainwave patterns.
Think of your brain as a bustling city. Just as electronic signals control traffic lights and telephone lines, electrical signals are constantly flowing in your brain, guiding everything you think, feel, and do. An EEG is like a test that maps the city’s electronic traffic.
The computer records these signals as a series of wavy lines, which your neurologist can then
review. Just as a traffic jam might indicate a problem on a city street, certain patterns of these wavy
lines can indicate different types of problems in the brain, such as seizures, sleep disorders, or other
neurological conditions.
During the EEG, small, metal discs called electrodes are attached to your scalp with a special paste. These electrodes are like the city’s traffic cameras: they will capture electrical signals in your brain and send this information to a computer.
The small metal disc electrode will not cause pain. The test usually last about half an hour to an hour, and the electrode sensor is removed thereafter. The patient can wash off the paste easily after the test.
Because an EEG is simply recording the electrical signals in your brain, the test is safe and painless. However, you may feel a little discomfort when the electrodes are placed on your scalp, similar to the feeling of someone gently pulling your hair.
EEG tests are commonly used in diagnosing various neurological conditions, studying sleep disorders, evaluating brain function, and researching brain activity. The doctor may request for an EEG if a neurological condition such as epilepsy, sleep disorders, or other neurological condition is suspected.
Remember, an EEG is just one tool that doctors use to understand what’s going on in your brain. If your doctor recommends an EEG, it’s to gather more information so they can provide the best care possible for you
