The National Hospital for Neurology and Neurosurgery (NHNN) has one of the largest, most comprehensive programmes in Europe for the evaluation and medical and surgical treatment of epilepsy.

Our multi-disciplinary team of world-leading experts includes neurologists, neurosurgeons, neuro-psychiatrists and neurophysiologists – working closely with epilepsy nurse specialists, neuro-psychologists and other specialties within the NHNN.

Based at Queen Square in central London and Chalfont St-Peter  the epilepsy group works within UCLH NHS Foundation Trust and has close links with UCL Queen Square Institute of Neurology and UCL Partners, including Great Ormond Street Hospital and UCL Great Ormond St Institute of Child Health.

These links allow the epilepsy group to evaluate and treat the widest range of patients – ranging from individuals seeking diagnosis after their first seizure – to more complex cases, including those for whom epilepsy forms only part of a broader medical or surgical condition.
