Show all keywords aivosähkökäyrä EEG Epilepsia An EEG is used to study disorders of the brain, especially different types of seizures and disorders of consciousness. The examination measures electrical activity in the brain, eye movements, muscle tension under the chin, breathing movements and heart rate. The examination also includes a video recording. The Clinical Neurophysiology Unit performs EEG examinations by appointment at the Tyks Lighthouse Hospital and, as necessary, on an emergency basis on the various wards of Tyks, including the neonatal, paediatric and adult intensive care units. Additional information about EEG examinations Depending on the patient’s age and what is being studied, different recording, activation and preparation procedures can be chosen. The most common activation procedures are stroboscopic photic stimulation and deep breathing. Often the subject is instructed to stay awake the night before the examination or sleep for a shorter period to ensure that they will sleep during the examination. A standard EEG examination takes approximately 90 minutes. If necessary, an EEG examination can also be done as a long-term monitoring, either at home with a portable device (an ambulatory EEG) or as several days’ video monitoring at the intensive care unit, for example. The Clinical Neurophysiology Unit also performs video EEG monitoring (VEEG) spanning several days with the aim of recording seizures under controlled conditions.
