In order to support future management of this chronic condition, this study aims to evaluate existing clinical pathways in the management of patients with chronic headache - either referral to the Neurology Department or direct access to Imaging. Participants will be followed-up for a period of 12 months after the initial Secondary Care episode (either an MRI scan or Neurology appointment). Costs from the NHS perspective and self-perceived patient quality of life will be assessed and cost per patient and cost-effectiveness analyses will be performed.
