EEG for adults

• It is recommended to wash your hair, after washing your hair you should not use any cosmetics (e.g. hairspray, gel, mousse, conditioner, etc.).
• You should come for the examination after a meal, rested and well-slept.
• Before the examination, it is not recommended to consume beverages containing large amounts of caffeine (e.g. strong coffee, cola, strong tea), high-energy drinks or alcohol.
• Do not discontinue your current medication. Bring a list of your current medications and supplements (especially vitamin D) to your examination.
• It is recommended to present descriptions of previous tests (if performed).
• During the examination, the patient is asked to turn off their mobile phone.

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

The test utilizes so-called activation methods , including photostimulation, hyperventilation, and the hold response. Activation methods are used to obtain additional diagnostic information.
Photostimulation (FS) involves exposing the subject to a variable, rhythmic stroboscopic stimulus from a distance of approximately 20-30 cm from the eyes. Hyperventilation (Hv) involves taking deep breaths for three minutes, while the hold response (OZ) involves opening and then closing the eyes for several seconds.

This examination facilitates the differentiation between functional and organic brain disorders. In many brain conditions, the examination allows for localization of the disease process to a specific area. This examination is particularly important in patients with epileptic seizures, encephalitis, cranial trauma, and in the differentiation of comas. This examination is an auxiliary method in the assessment of patients with brain tumors and vascular brain damage (following cerebral stroke). A head EEG allows for the diagnosis of various neurological or psychiatric complaints.

Typically, the examination is performed in a supine position (if indicated, the examination is performed in a sitting position). During the examination, the patient's eyes are closed and they follow the staff's instructions. The patient lies still, does not move, and does not talk during the examination, as such behavior may generate graphoelemental phenomena of extracerebral origin.
The examination is painless and non-invasive.

• diagnosis of epilepsy – diagnosis, monitoring of treatment, making decisions about discontinuing medication,
• loss of consciousness, fainting,
• disturbances of consciousness,
• headaches, dizziness, migraine,
• craniocerebral injuries (and their consequences),
• strokes (and their consequences),
• brain tumors,
• convulsions (hypoxia, metabolic disorders, febrile),
• cerebrovascular diseases and their consequences,

• disorders of psychomotor development in children,
• emotional disorders,
• attention deficit disorder,
• disorders of cognitive functions and learning processes (school difficulties),
• anxiety states,
• attention deficit hyperactivity disorder (ADHD),
• delayed psychomotor development,
• diagnostic test before EEG-Biofeedback training,
• in serial EEG examinations it facilitates the dynamic assessment of disease symptoms.

• stitches on the head (the examination can be performed one week after the stitches are removed).
