However, nitrous oxide is known to irreversibly inactivate the functioning of vitamin B12, a vitamin required for the maintenance and proper functioning of nerves in the spinal cord. Neurological symptoms in this population have been reported in around 3.4% of nitrous oxide users, although the true incidence is expected to be higher as the cases being reported by UK hospitals continues to rise. Patients may present with adverse neurological symptoms like tingling, weakness, coordination and mobility problems. Currently, studies reviewing the functional recovery of these patients have been limited by a retrospective study design, short follow up duration and being limited to small cohort sizes. This is in part linked to patient non-compliance and non-attendance at follow-up appointments. The investigators will therefore prospectively recruit all patients presenting with these symptoms and continue to collect data relating to their neurological recovery for 12 months.
