EEG - Electroencephalography

is a test that records electrical brain activity. Nerve cells transmit signals to each other by changes in electrical voltage. Changes in electrical voltage propagate to the surface of the head where they are registered by sensitive electrodes and recorded on a graph. EEG is mainly used in the diagnosis of epilepsy and sleep disorders, but also in patients with migraines, after loss of consciousness of unexplained cause, strokes or brain injuries. Two EEG machines are located in the neurology department. EEG is an essential investigative methodology for the diagnosis of epilepsy. The EEG includes several electrodes (16 to 25) which are connected to an evaluation device - a computer. The examination does not require any special preparation. The EEG is performed as an outpatient examination. A special cap with electrodes is placed on the patient's head, on which a conductive gel has previously been applied. After the cap is placed and connected to the machine, the patient is laid down on the examination bed. The whole examination takes up to 45 minutes. During the examination, the patient is occasionally asked to close or open his eyes for a certain period of time and to breathe deeply and quickly. At some stage, the patient is also exposed to flashes of light, so the EEG may show the sensitivity to light (photosensitivity) that is present in certain types of epilepsy. The EEG examination has no risks, does not expose the patient to any harmful effects and is not painful. There is no need for special preparation for the EEG examination. However, if you are planning a visit to the hairdresser, for example, it is better to postpone it until after the EEG examination, as your hair may get "messy" during the examination.

The examination is ordered by a neurologist and a referral with a completed application form is required. The result of the examination is available in the interval after the description by the doctor.
