Headache service

Service detail

The headache service provides clinics to support four consultants specialising in headaches. 

The clinics consist of:

  • Follow up review clinics for all headache disorders
  • Botulinum toxin injection clinics
  • Nerve block injection clinics
  • Anti–calcitonin gene related peptide review clinics

Headache chatbot service

The Walton Centre is currently in the process of developing a chatbot to provide specialist advice to patient suffering for headache symptoms.

Patients being referred to a neurology headache specialist will be invited to engage with the chatbot to collect details of their condition and the symptoms through a structured set of questions in addition to that provided in their GP referral letter. This will be used to compile a detailed medical history which clinicians can review before the first appointment with the patient and recommend a course of action if appropriate.

Depending on the clinician’s assessment, patients may be put on a fast-track to be examined by a consultant or offered guidance on alleviating symptoms while they await their referral appointment.

There is limited access to the system whilst it is being trialled with selected patients. If you have received an invitation to use this chatbot service, please click here.

Please note that by completing the chatbot questionnaire, you are consenting for your information and data to be processed under GDPR Article 4(11).
