Recently a text message was sent to some patients and carers from us by mistake. We're sorry for any confusion this has caused.
Strike action is taking place in September and October. We'll contact you directly if you or your child's appointment is affected.

Your child's TANDeM outpatient appointment

Outpatient clinics are held every Thursday, 10am-4pm in the Children’s Neurosciences Centre (Newcomen Centre), 1st floor, South Wing, St Thomas' Hospital.

How do I get an appointment?

We accept referrals from local specialist services (for example, paediatricians, child and adolescent health services).

We also accept GP referrals where there is a service based locally who we can liaise with.

Cancelling or changing your appointment

To change or cancel your appointment contact the appointments office on 020 7188 4000 or email

Before your appointment

Please bring a list of any medications your child is currently taking, any relevant reports and your child’s red book (personal child health record).

Relevant reports may include clinic letters from local services, school reports and statements and cognitive assessments.

What to expect at your appointment

You will be seen by Dr Tammy Hedderly (consultant paediatric neurologist) or a senior member of the TANDeM team.

Support is also provided by our clinical nurse specialist and psychology research assistant. See the TANDeM team page for more information about our members of staff.

Your first appointment usually lasts about an hour. This involves talking about your child’s symptoms and other relevant information in order to reach a diagnosis.

The doctor or nurse will examine your child. If necessary, your child may also need to have additional tests such as:

For most children, we are able to give you a diagnosis about your child's condition at the first appointment. We will also be able to provide some information about your child’s condition and discuss possible treatment options (for example medication or psychological therapy).

As this is a teaching hospital, students supervised by qualified staff might be involved in your care. It is valuable training for students and does not affect the quality of your treatment in any way, but please tell us if you do not want them to be present or involved. We will always respect your wishes.

After your appointment

All the information discussed at your appointment, including diagnosis and treatment recommendations, will be sent in a letter to you and your GP. If we have recommended any medication for your child, this will be arranged by your local service. 

After diagnosis we will work with your local services to ensure that your child is offered the most appropriate and convenient support. This may involve a referral to child and adolescent mental health services (CAMHS), a community clinic or local hospital.

We are happy to be contacted routinely for advice and support. However, we do not provide an emergency service. This is why it is very important that your child has a local service (GP, CAMHS or community paediatrics) to respond to any urgent issues and prescribe medication where this is recommended.
