Some people with epilepsy have seizures that are started, or ‘triggered’, by flashing lights. The test may include deep breathing to see if epileptiform activity can be provoked and recorded. Some people can have epileptiform brain activity even when they do not appear to be having a seizure, so an EEG can be particularly useful for them.Įpileptiform activity can sometimes be provoked (brought on) by deep breathing. This change, known as epileptiform brain activity, can sometimes be seen on an EEG recording.
When someone has an epileptic seizure their brain activity changes. The recording shows how the brain is working.Īn EEG gives information about the electrical activity of the brain during the time the test is happening. These signals are picked up by electrodes attached to the head and are recorded on a computer. Queen’s Memorial Fund & book of condolencesĪn Electroencephalogram (EEG) records the electrical activity of the brain by picking up the electrical signals from the brain cells.Her Majesty The Queen: 70 years of service.Sudden Unexpected Death in Epilepsy (SUDEP).Care and treatment: your rights and choices.
