Institute Description

In 2011 Dr Hedderly established the TANDeM service with the support of a GSTT Trust ‘new and innovative’ service grant. This is now an established multi-disciplinary clinic within the paediatric neurosciences directorate with input from Child and Adolescent Psychiatrist, Specialist Clinical Psychologists and a Liaison nurse specialist. It is a weekly clinic and attracts a wide number of local as well as district and some national referrals. The clinic sees several patients per week for assessment, investigation and diagnosis as well as ongoing management which includes psychosocial, behavioural therapy and pharmacological treatments. Evelina Children’s Hospital sits within Kings Health Partner, AHSC which includes GSTT, KCL and the Maudsley Institute of Psychiatry. It has the aim to create a centre where world-class research, teaching and clinical practice are brought together for the benefit of patients. TANDeM has close links to the adult neuroscience centre, Clinical and research genetics department, neuro-immunology services, metabolic medicine and neuro-imaging services as well as full access to neurophysiology services.

The TANDeM Service is leading on UK PI for EMTICS, a European multicentre study (EMTICS) investigating the Paediatric Autoimmune Neuro-Psychiatric Disorders Associated with Streptococcal (PANDAS) infections hypothesis. We are also participating in TICGEN an International Project to explore the genes and neuro-biology of Tic disorders. We hold several grants including for Nurse led Intervention supported by Roald Dahl and for psychological therapies such as ‘mindfulness’. The TANDeM team includes Dr Peter Hindley, Dr Sally Robinson, Claire Grose, Dr Anya Kaushik, and Alison Corpuz.
