Simon Freilich has been a consultant in clinical neurophysiology since 2015 and leads a regional service covering a population of over 600,000. Having trained across London's top teaching hospitals, Simon covers the full spectrum of neurophysiological techniques, from neonates to centenarians. His particular interests include peripheral nerve injuries, neuro-muscular junction transmission disorders, and complex epilepsy. Simon provides detailed insights into clinical neurophysiology through his dedicated YouTube channel, which offers information about the tests and conditions he diagnoses. His expertise includes nerve conduction studies and electromyography (NCS/EMG/QEMG/SF-EMG), evoked potentials (SSEP, MEP, ERG, VEP, BSAEP), and electroencephalography (routine, sleep-deprived, video-telemetry, ambulatory). He specializes in diagnosing and treating nerve injuries, nerve entrapment, neuro-muscular diseases, and epilepsy.
