An electroencephalogram (EEG) is a test that uses small metal discs connected to the scalp to identify electrical activity in the brain. Even though you’re sleeping, your brain cells interact with each other via electric signals. On an EEG recording, this activity appears as wavy lines. One of the most used epilepsy diagnostic tests is an EEG. An EEG can also be used to diagnose various types of brain diseases.
Why Is Electroencephalogram (EEG) Conducted
An EEG can detect variations in brain activity that can aid in the diagnosis of several brain illnesses, including epilepsy and other neurological diseases. An EEG can also be used to diagnose or cure the following conditions:
- Brain damage
- Stroke
- Brain tumor
- Sleep disorders
- Brain dysfunction
Furthermore, an EEG can also be used to verify brain death in people who have been in a coma for a long time. In a medically induced coma, a continual EEG is utilized to help determine the appropriate level of anesthetic.
What To Expect During The Procedure
During an EEG, you should feel little to no discomfort. There are no sensations transmitted by the electrodes. They simply take notes on your brain waves. You can also expect the technician will take your head measures and mark your head with a special pencil to show where the electrodes should be attached.
A technician will also attach discs to your head employing an adhesive. An electroencephalogram (EEG) can take up to sixty minutes once the electrodes are put. Such conditions necessitate sleeping during the examination. The test can be extended in this case.
Moreover, during the test, you rest in a relaxed position with your eyes closed. Finally, during the EEG, the video is regularly recorded. The camera captures the body movements, while the electroencephalogram (EEG) records the brain waves.
What Should You Expect After The Test?
The cap or electrodes are removed by the technician. If you didn’t take a sedative before the surgery, you should have no adverse effects and be able to resume your normal habit right away. However, if you took a sedative, it would take some time for the effects to pass off. Make arrangements for somebody to take you home. Relax and don’t travel for a whole day once you’ve arrived home.
