eeg(Electroencephalography)

  • Electroencephalography (EEG) is the examination of the basic bioelectrical activity of the brain. The procedure is performed by placing small electrodes on the scalp.

  • While you do not get hurt during EEG recording, it is enough to stay calm and still for a while.

  • EEG is an electrophysiological study performed on epilepsy patients or patients with pre-diagnosis of epilepsy. Patients should have a full stomach and clean hair.

  • It is recorded and interpreted with the electrodes connected between the hairs. The purpose of the EEG is to see the damages in the brain. These damages may occur in the womb of the mother, and then may occur as a result of a blow to the head or as a result of a febrile illness. It is especially applied in patients with epilepsy. There are two types of EEG recordings. There are 16 electrodes. 8 of them are attached to the right side of the head and 8 of them to the left side of the head, starting from the forehead to the nape, and shooting is done. During the shooting, the patient is placed on a stretcher and kept still.
     

HOW IS EEG taken?

  • The electrical activity of the brain is transmitted to the EEG device through small metal electrodes placed on the scalp of the patient, and the data is recorded on the computer for an average of 20 minutes.

  • Electricity is not supplied to the patient during the shooting and the patient does not feel any pain.

  • In order to obtain an interference-free, quality recording, the patient should keep their eyes closed, their jaw and neck muscles relaxed, and stay as still as possible, unless otherwise requested.

  • In the 3rd minute of the shooting, the patient is asked to breathe deeply, and in the 10th minute of the shooting, he is asked to look at the light source that is given intermittently.
     

  Coming to Shoot

  • It is useful to wash the hair in the morning of the shooting day in order to ensure that the EEG examination is free of interference.

  • If there are drugs that are used continuously, the drugs are continued to be used on the day of the shooting. It would be appropriate to inform the physician who will evaluate the EEG.

  • As it can be understood from this article, headaches that can be considered insignificant should be considered, and if the pain is very severe and lasting for a long time, a doctor should be consulted. Let’s not forget that we are given the chance to live once, so let’s evaluate it.
