EEG for adults

• It is recommended to wash the head, after washing the head, do not use any cosmetics (such as hairspray, gel, mousse, conditioner, etc.).
• You should come to the examination after a meal, rested and sleepy.
• Before the test, it is not advisable to consume beverages containing large amounts of caffeine (such as strong coffee, cola, strong tea), high-energy drinks or alcohol.
• Do not discontinue any ongoing drug treatment. You should bring a list of continuously taken medications and supplements (especially vitamin D) to the examination.
• It is recommended to provide descriptions of previous examinations (if performed).
• For the duration of the examination, the patient is asked to turn off his cell phone.

 EEG - is a non-invasive method of studying changes in brain potentials using an apparatus called an electroencephalograph. Electrodes connected to a bioelectric amplifier (head) are placed on the patient's scalp. The bioelectrical signal obtained is recorded in the form of various brain waves, which are analyzed. The purpose of the test is to record and interpret the bioelectrical activity of the brain.

The study uses so-called activation methods of recording, namely photostimulation, hyperventilation and stop response. Activation methods are used to obtain additional diagnostic information.
Photostimulation (FS) involves exposure from a distance of about 20-30 cm from the subject's eyes to a variable, rhythmic stroboscopic stimulus. Hyperventilation (Hv) involves taking deep breaths for 3 minutes, while the stop response (O-Z) is the opening and then closing of the eyes for several seconds.

The examination facilitates the differentiation of functional and organic brain disorders. In many brain disorders, the examination allows localization of the disease process in a specific area. The examination is particularly important in patients with epileptic seizures, in the course of encephalitis, after cranial trauma and in the differentiation of coma. The test is an auxiliary method in the evaluation of patients with brain tumors and vascular brain damage (after cerebral strokes). EEG examination of the head makes it possible to examine various complaints of neurological or mental origin.

Normally, the examination is performed in the supine position (if there is such an indication the examination is performed in the sitting position). During the examination, the patient has his eyes closed and follows the instructions of the staff related to the implementation of the examination. The person under examination lies quietly, does not move or talk during the examination, as such behavior can generate graphemes of extracerebral origin.
The examination is painless and non-invasive.

• In serial EEG studies, it facilitates dynamic assessment of disease symptoms.

• sutures on the head (the test can be performed one week after the removal of the sutures).
