: This study will not change local routine practice and will use data obtained as part of usual care. The UK Health Research Authority (HRA) decision tool has confirmed that this study is not considered research by the NHS and does not require NHS research ethics committee approval (Supplement S) [].The centre lead and accompanying research team at each unit are responsible for registering the study with appropriate approvals, in line with national guidelines. In the UK, this will usually be as a service evaluation study. Supervision by a local neurology consultant is required for this process, therefore it is the responsibility of the local teams to identify suitable consultants for study registration. Collaborators will be required to confirm that a local approval is in place prior to data collection. As a service evaluation study, explicit informed consent was not obtained from each participant, but the study complies with national NHS data opt-out guidance.
