Who's involved Partners SLAM South London and Maudsley NHS Foundation Trust provide the widest range of NHS mental health services in the UK. They also provide substance misuse services for people who are addicted to drugs and alcohol. They are the only mental health trust in the UK to have our own biomedical research centre (BRC) – hosted jointly with the Institute of Psychiatry, Psychology and Neuroscience (IoPPN) King’s College London with the aim of translating scientific developments into new ways of screening, detecting, treating and preventing mental illness. The Trust’s scope is unique because it is built on the principles of Henry Maudsley when he founded the Maudsley Hospital in the early 1900s: care and treatment, science and research, and training. Its history can be traced back to 1247 when Bethlem Royal Hospital was founded on a charitable deed. Today our charity continues as the Maudsley Charity.
