Dr Kapoor is a Consultant Neurologist based at the National Hospital for Neurology and Neurosurgery, Queen Square, and an Honorary Senior Lecturer at the Institute of Neurology.
He trained in Oxford (BA Physiological Sciences, 1st class Honours, 1978; BMBCh, 1981), specialised in general medicine in London, and then did research in basic neurobiology in New York and in Oxford. He returned to complete his neurological training at University College London Hospitals and the National Hospital, and took up his present post in 1994.
At the National Hospital, he supervised the headache service initially, and then moved on to focus on the diagnosis and treatment of inflammatory disorders of the nervous system, particularly multiple sclerosis. He was Associate Clinical Director at the National from 2001-3. Until 2008, he was also attached to Northwick Park Hospital, where he ran the general neurological service, and helped to set up the service for acute stroke.
Dr Kapoor maintains clinical interests in general neurology and in multiple sclerosis. He has also continued his research work to uncover some of the basic mechanisms by which the brain is affected in MS, how these might be treated to prevent disability. He has published numerous articles on general neurological disorders, and on the clinical, therapeutic and basic aspects of neuroinflammatory diseases.
