EEG (Electroencephalogram)

What is EEG?
The test performed to examine the electrical activity produced by nerve cells in the brain is called Electroencephalography (EEG). This test, which helps evaluate brain functions, is performed for diagnosis and follow-up purposes.

EEG is performed by placing electrodes on the patient’s head with the help of a paste according to the limbic system of 10-20. The cables connected to the patient do not provide electricity, they only transfer the brain’s electrical signal to the computer and create a trace.

EEG STUDIES

1- Routine EEG

2- Sleep EEG

3- Sleep-wake EEG

4- Video EEG

Things the patient should pay attention to before the shooting

The patient should not sleep at night.
There should be no caffeine consumption for 24 hours before the shooting.
The scalp should be clean. (No gel, foam, hair spray, etc.)
The patient should be full.

How is the shooting done?

In routine EEG, the patient is in a resting position and the recording takes about 15-20 minutes. The patient does not feel any pain or ache during the EEG recording. During the recording, there are EEG activations called

Eye opening and closing,
Hyperventilation
Photic Stimulation
applications are performed.

After all the procedures are completed, the patient is separated from the electrodes and the shooting is completed.

Sleep EEG:

Sleep EEG examination is requested to detect EEG changes specific to sleep periods and sleep transitions. It is an examination performed during the day or night, for 1 hour or 3 hours, and throughout the night.
