EEG is a short form for electroencephalogram and is used to detect your brain activity and if there are any abnormalities present in the activity pattern. The test is very simple and is harmless. Being a non-invasive test it does not cause the patient any pain nor does it leave any scarring.
Brain cells communicate with each other in the form of impulses and the test records these brainwaves on a computer. The results from the EEG test look like wavy lines and as having valleys and peaks, similar to a heartbeat pattern. The doctor can easily analyze these results and determine if there are any abnormalities present in the brain.
When is EEG Performed?
As an EEG test records your brain activity, it can shed light on whether the brain is functioning properly or not. The doctor will prescribe this test to determine or to rule out any brain disorders.
Diagnose Epilepsy or other disorders which cause seizures, and see the type of seizures that are occurring
Check for any internal head injuries
Dementia or to check if there are any problems with the loss of consciousness
Find out if the patient’s brain is functioning or not while in a coma
Keep a check on brain activity while surgery is being performed on the brain
Detect strokes
Check for inflammation of the brain (Encephalitis)
Study any presence of sleep disorders, such as Narcolepsy
What is the EEG Procedure?
EEG is one of the simplest of tests. It does not cause any pain as it is non-invasive, unlike other tests which usually use syringes to take blood samples. The procedure includes the placing of electrodes on the scalp, each of them having its own individual wires.
The scalp is prepared for the test by cleaning it and removing dead skin cells and applying a gel or a paste before placing the electrodes. The patient experiences no pain in this procedure. The patient may be advised to stop taking certain medications before the procedure and they should consult the doctor about the medications they are taking. In some cases, the patient is also advised to avoid any coffee as it might alter the test results.
As the test is fairly simple, it can be performed in a small area in the doctor’s office or in the hospital. The patient is asked to sit in a chair or lie down on the bed. The EEG technician then begins to attach the electrodes to the scalp at pre-decided locations after applying the paste or gel. All the electrodes are connected to the EEG recording machine.
Most of the EEG tests take up to an hour to perform but those involving sleep analysis take more. The family members can stay with the patient if the doctor allows. Sometimes the patient may be required to sleep as little as possible the night before the test to get the best results.
This is generally done when the patient is required to sleep during the EEG. The doctor may also give the patient a sedative to help them to relax and sleep while the test is being performed.
After the test has been performed the EEG technician will come and remove the electrodes from the scalp of the patient. There are no side effects to the procedure but the sedative may take time to wear off if the patient has been given one.
The patient might not be allowed to drive or use any heavy machinery. If the patient is not under any sedative, they can continue with the normal routine of the day.
