Intracranial Monitoring

Using state of the art technology, our physicians are able to monitor the characteristics of an individual’s seizures and their correlation with an EEG. Monitoring, some of which takes place in the Johns Hopkins Epilepsy Monitoring Unit (EMU), may include:

  • Ambulatory monitoring – The use of a cassette-like tape recorder (which can record up to a 72-hour period) to monitor the EEG while a patient is awake at work, school, or play. The amount of information produced and recorded about specific parts of the brain is limited, so it is only useful in special situations.
  • Prolonged EEGs – The method of monitoring the electrical signals of the brain by attaching electrodes (sensors) to the scalp.
  • Prolonged video-EEG monitoring – The use of a video camera to capture onset and characteristics of a seizure simultaneously with an EEG.
  • Depth electrodes – Small, multi-contact probes that are inserted into specified areas of the brain via holes made in the skull/covering of the brain.
