The National Hospital for Neurology and Neurosurgery (NHNN) was the first hospital of its kind in England, being dedicated exclusively to treating the diseases of the nervous system. It is located at Queen Square, London. It is affectionately known as the 'The National', and less correctly as 'Queen Square'.
Since 1996 it has been part of University College London Hospital NHS Trust. It is associated with the Institute of Neurology (part of University College London), a major research centre, and supports the Sir William Gowers Epilepsy Assessment Unit at the National Society for Epilepsy Centre at Chalfont St Peter, Buckinghamshire.
The NHNN also runs The National Hospital Development Foundation, a charity dedicated to supporting the Hospital for the funding of equipment, buildings and research.
