Personal profile

Dr Suzanne O’Sullivan has two areas of speciality. She is both an accredited neurologist and clinical neurophysiologist. She has worked as a consultant in both specialities since 2004 and is currently based at The National Hospital for Neurology in central London and also at The Epilepsy Society in Chalfont St Peter. Prior to being appointed to those posts she had also worked as a consultant neurologist/neurophysiologist in the very busy acute medicine environment of the Royal London Hospital.

Dr O’Sullivan practices all areas of general neurology and neurophysiology. She has an active interest in finding the cause for and treating headache and has a particular interest in finding the cause of blackouts or episodic strange symptoms such as dizziness or collapse or odd feelings that come and go. 

As a Neurophysiologist Dr O’Sullivan carries out EMG (electromyography) and nerve conduction studies to investigate back problems and nerve and muscle problems. She also has extensive expertise in the reading EEG (electroencephalograms) as part of the investigation of epilepsy and memory disturbance. At the Epilepsy society she runs a successful videotelemetry service to investigate and help treat those with previously resistant blackouts and epilepsy.
