Electroencephalography – EEG – after all night sleep deprivation

Services

EEG after sleep deprivation is imaging taken after a fully or partially sleepless night (deprivation/partial sleep deprivation). The aim of this examination is to make the patient feel fatigued after sleep deprivation and fall asleep in the EEG office in the morning (during regular office hours).  The electrical activity of the brain is recorded in wakefulness just before sleep, after falling into sleep, during sleep, and after sleep, while being awake.  The examination takes about 90 minutes. This examination can detect changes in brain electrical activity that cannot be obtained by standard EEG imaging, which are extremely important for the diagnosis of epilepsy and other diseases.

INDICATIONS / WHY IS IT PERFORMED?

It is used in the examination of patients who have experienced a crisis of consciousness, who have lost consciousness, or in the examination of a crisis of consciousness in patients who most often experience it at night.

HOW IS IT PERFORMED?

  • A special cap is placed with electrodes or individual electrodes are applied to the surface of the head with the help of a gel.
  • Examination is performed in a lying or sitting position with your eyes closed, in a position that is comfortable for you. The basic EEG is first recorded for 10 minutes.  You will need to open or close your eyes or breathe deeply during the basic EEG imaging. Blinking light is used at the end of the imaging.
  • The EEG is then recorded when you sleep (for about an hour) and as you wake up.

POTENTIAL RISKS

  • EEG imaging is completely painless.

PREPARATION

  • You must not sleep the night before the test.
  • If you are screened after partial sleep deprivation, you may sleep for up to 4 hours.
  • Avoid consuming caffeinated beverages (coffee, tea, cola) as they may affect test results.

AFTER THE EXAMINATION

It is recommended that you rest and sleep and do not drive a motor vehicle on that day.
