Hi A friend is at University College London Hospital, their neuro service is at https://www.uclh.nhs.uk/our-services/our-hospitals/national-hospital-neurology-and-neurosurgery and she is really pleased with dilligent and efficient care from the entire team. If something is truly worrysome, she is being seen quickly. For routine care, appointments can be a bit of a wait though. Good luck and welcome to London!
