Dr O'Sullivan does not accept self-referrals. Prospective patients must be referred by a healthcare professional — typically a GP or Consultant doctor.

Please bring a list of your current medications (including over-the-counter and supplements) and any previous investigation results (MRI scans, blood tests). A completed headache diary — even a simple note of frequency, duration, severity, and associated symptoms — is extremely helpful.

To ensure you get the maximum benefit from your clinical appointment, if possible please complete a registration form, which can be downloaded here.

A new appointment will take approximately 30 minutes and a follow-up 10–20 minutes. Please allow adequate time and avoid scheduling commitments immediately afterwards.

Not necessarily. Most patients with a long-standing headache history and a normal neurological examination do not require brain imaging. If there are features warranting further investigation, an MRI or CT scan may be arranged and this will be discussed with you at your appointment.

You will receive information regarding the fees along with your appointment letter.

Please remember that seeing a Private Neurologist is a contract between you and that Doctor. If you have private health insurance this may reimburse you for the whole or part of that cost, but ultimately it is the patient who is responsible for the fees in line with the contractual arrangement with that Doctor. Whilst an average time is given for a consultation it may be longer or shorter depending on necessity.

Dr O'Sullivan may also suggest investigations (for example blood tests or scans) and it is difficult to predict these in advance. Normally, your insurance company should meet these costs but these are again your responsibility.

If you have any questions, please call your insurance provider and Dr O'Sullivan's practice manager to discuss prior to consultation.
