I am a consultant clinical neurophysiologist and CEO of the charity TeleEEG. As a clinical neurophysiologist I help diagnose conditions of the brain and nervous system using electrical techniques. One of the tests I use to help in the diagnosis of epilepsy is electroencephalography (EEG). EEG involves measuring the brain waves of people by applying electrodes to the scalp and recording the electrical activity. I have been carrying out this activity in the NHS now for over 20 years. Further, TeleEEG has around 50 clinics throughout the world helping diagnose epilepsy in under resourced countries.
