Waking electroencephalography (EEG) for adults

Waking electroencephalography (EEG) for adults

The examination involves registering the changes in the electrical potential on the surface of the scalp, coming from the activity of neurons of the cerebral cortex. The examination is performed with the patient in a horizontal position, wearing a special cap with registering electrodes.

A medical prescription is required for the examination, with a clearly specified waking EEG service to be provided.

Encephalography is used, amongst others:

• in the diagnostics of epilepsy;
• in determining the causes of sleep disturbances;
• in assessing the condition of brain, e.g. after poisoning with neurotoxic substances, after neurosurgical operations;
• after head injuries;
• in frequent headaches.

The service above concerns waking electroencephalography (EEG). If you wish to schedule a sleep examination, choose the service: “Sleep electroencephalography (EEG)".

Preparation for test

• The patient should be after a meal, preferably an easily digestible one.
• The hair should be freshly washed, without any hairspray, gels, oils, decorations, dreadlocks, etc.
• The patient should be healthy with no signs of infection.
• On the examination day, prescription drugs should be taken as usual, while all other substances used out of the patient’s own free will should be discontinued 2-3 weeks before the examination. Moreover, the patient should know the names and doses of the medicines used.
• The day before the examination, it is forbidden to consume alcohol and use any substances such as recreational drugs and designer drugs.
• On the examination day, it is important to refrain from eating chocolate and drinking caffeinated beverages (e.g., coffee, cola).
• The patient should arrive for the examination after a good night’s sleep.

Important information

• medical prescription with a clearly specified service to be provided is required for the examination.
• The examination is performed both in adults and in children who can lie still for 20 minutes (in children up to the age of 4 years, the only option is to perform the sleep EEG).
• In the case of resignation from or rescheduling of the EEG examination, we kindly ask our patients to cancel their booking. The earliest possible cancellation will make it possible for us to perform the examination for another patient, while keeping an adequate amount of time for such patient to prepare for the examination.
• It is very important for the patient to arrive on time.
• Information on the collection of the EEG results is given by the technician during the examination. The result of the examination is issued in a paper form, but at the patient’s request it may also be issued on a CD (at no additional charge).
• If the patient has to undergo sleep electroencephalography (EEG) and waking electroencephalography (EEG), it is necessary to schedule the examinations for two separate days due to different preparation procedures.
