An electroencephalogram (EEG) is a device that measures brain activity. Your brain sends out small electrical impulses all the time. Small sensors called electrodes are put on your scalp during an EEG exam. An EEG machine is linked to the electrodes via cables. A specific paste adhesive or paste is used to connect the electrodes. You may still have a lot of adhesive in your hair once the electrodes are removed. A hair conditioner might aid in the removal of the adhesive.
The electrodes pick up your brain's electrical impulses and record them on a computer. Only electrical impulses are picked up by them. They have no effect on your brain and do not cause you any discomfort.
When do EEG tests take place?
An EEG (electroencephalogram) test may be requested by your doctor for one of the following reasons:
-
They believe you have epilepsy.
-
They need to know more about your epilepsy because you have it.
-
They're not sure if your seizures are caused by epilepsy.
-
Epilepsy surgery is being considered for you.
-
They want to take your epilepsy medications away from you.
An EEG device is sometimes used to determine whether someone is suffering from non-convulsive status epilepticus. Non-convulsive status epilepticus can alter a person's consciousness or create confusion, but without an EEG, it may not be recognized as a seizure.
The findings of an EEG can assist doctors in making the proper diagnosis and selecting the most appropriate therapy. They should always be read by a doctor who specializes in EEG device interpretation. This is because misreading an EEG is one of the most prevalent causes of people receiving erroneous diagnoses.
