The child and adolescent psychotherapy discipline at University College London Hospital (UCLH) is part of the Department of Child and Adolescent Psychological Medicine, which also comprises teams of clinical and systemic psychologists and child and adolescent psychiatrists. With two other child and adolescent psychotherapists and a child and adolescent psychotherapist in training, we provide a psychoanalytic psychotherapy service to children and their families and to young people referred from within the hospital. We dedicate a significant proportion of our time to work with the young people who are treated in the teenage and young adult service, as well to the many young children who are treated here for their cancer in the paediatric service. A high proportion of children with brain tumours come to UCLH for radiotherapy treatment.
