Professional background
Dr Simon Farmer is a consultant neurologist with particular expertise in general diagnostic neurology, movement disorders, neuro-ophthalmology and spinal disorders. He qualified from Bristol University in 1986: BSc-Pyschology 1st Class Honours, MbChBHe Completed a PhD in Physiology at UCL in 1990 as Welcome Trust Medical Research Training fellow.
He trained in General Medicine and Neurology at the Royal London Hospital, the National Hospital for Neurology & Neurosurgery and St Mary's Hospital, London (MRCP-1992, FRCP-2000). He was appointed consultant neurologist St Mary's Hospital and the National Hospital in 1995.
General neurology and acute liaison neurology: Between 1996 and 2010 at St Mary’s / Imperial College NHS Trust and the National Hospital for Neurology and Neurosurgery, Queen Square, Dr Farmer offered a consultant-lead general neurology service (two clinics per week; 14 neurology in-patient beds) and along with colleagues a 24/7 acute neurology liaison support service to one of London’s premier general teaching hospitals (St Mary’s, Paddington). This work included diagnosis and management of the entire range of undifferentiated acute neurological illness, e.g. Stroke, Myasthenia, Guillan-Barre, Status Epilepticus, CNS infection. Since his move to a full-time NHS post at the National Hospital, Queen Square in 2010, in addition to his sub-specialist interests Dr Farmer continues to offer an outpatient and inpatient general neurology service.
Movement disorders and Parkinson’s disease: Dr Farmer ran the St Mary's Hospital Movement Disorder service from 1996-2010 and he continues this work at the National Hospital for Neurology and Neurosurgery in London. He is a consultant within the movement disorder service at the National Hospital and specialises in the diagnosis and treatment of Parkinson’s disease, tremor, dystonia, myoclonus, ataxia and functional movement disorders. He works with the functional neurosurgery team at the National Hospital and is principal investigator within the Institute of Neurology’s Sobell Department of Motor Neuroscience and Movement Disorders
Neuro-ophthalmology: Dr Farmer co-ran with first Mr James Acheson and subsequently with Mrs Veronica Ferguson a weekly neuro-ophthalmology clinic at the Western Eye Hospital, London from 1998-2010. Acute neuro-ophthalmology problems e.g. severe optic neuritis, pituitary apoplexy, CNS vasculitis/Behcets and disorders of eye movements were admitted under his care to St Mary’s Hospital, London. Dr Farmer has expertise in the diagnosis and management of all aspects of neuro-ophthalmology and since May 2010 has continued his NHS neuro-ophthalmology work at the National Hospital, London. He continues to enjoy close working relationships with his previous as well as current consultant ophthalmologist and consultant neuro-ophthalmologist colleagues.
Medical management of spinal cord and spinal column disorders: Dr Farmer receives a number of referrals for second opinions from spinal orthopaedic and spinal neurosurgeon colleagues to his practices. He has written and edited significant sections in two major neurology text books in this area and has lectured on the ‘Imperial Spine Course’. His expertise in this field is in helping to guide decisions relating to surgical versus medical management of spinal cord and spinal column disorders.
Research and public engagement: Dr Farmer is active in basic and clinic neuroscience research at the Institute of Neurology and enjoys active collaborations with colleagues with other universities in the UK and abroad. He is the supervisor and mentor of a number of PhD students. He has been board member and trustee of the Bobath Foundation. He is involved with lecturing and running seminars in neurology and neuroscience for trainees and general practitioners. He has advised and taken part in the making of several television programmes relating to his research.
Research interests
His research interest is in the field on signal analysis of brain and muscle activity. Over a number of years he has studied synchronous and oscillatory drive to the motoneuron pool in humans through application of coherence and cross-correlation analysis. His group was the first to describe ~20 Hz synchronous drive to human motoneurons and provided the first demonstration of ~20 Hz coherence between brain and muscle recordings. His team's research has been applied to the clinical conditions of Parkinson's disease, tremor, dystonia, myoclonus, stroke, cerebral palsy, and pathological mirror movements.
Research projects include:
- Dynamical systems approach to normal and abnormal human motor development.
- The development of human oscillatory brain-muscle interactions.
- Human motor development
- The pulsatile control of human movement.
- Neurophysiological studies of mirror movements.
- Plasticity in the human motor system following stroke.
- Analysis and modelling of the pre-term EEG.
- Modelling of brain oscillator networks.
- Cortical network behaviour in low awareness states.
- Frontal lobe network interactions in reward tasks.
