disorders, which affect the electricity in the brain. For this reason, the results of an electroencephalography examination can show abnormal electrical activity which could be an indication of a disturbance in the patient's brain and nerves. This EEG tool is a diagnostic support, so it is complementary to a specialist doctor's examination according to the disease.

l Before doing an EEG (Electroencephalography) Test, make sure you have consulted with a Neurologist


In an EEG (Electroencephalography) examination, the procedure involves placing electrodes on the scalp to record electrical activity in various places on the head. During the process, brain activity will be recorded on a piece of paper called an encephalogram. During the examination, the patient is asked to lie down and remain calm. Some patients perform EEG procedures while the patient is asleep because some abnormally detected brain waves will only be seen when the patient is sleeping.


After the EEG (Electroencephalography) is complete and the medical team has received the results of the brain record, the electrodes will be removed from the head. Then at the point where the electrodes were installed, there may be redness or irritation of the scalp. But don't worry, this is normal and usually goes away. In this EEG test, the patient may feel dizzy and tingling in the lips and fingers in several parts after the examination is carried out. If this condition is quite disturbing, you should consult a Neurologist.
