The National Autism Unit is a national, specialist inpatient and day-care service based at the Bethlem Royal Hospital.

Autism Spectrum Disorders (ASD) and related disorders are lifelong neurodevelopmental conditions. However, they are often under-recognised in adults, particularly in adolescents, females and older adults.

We pioneered the development of specialist services for assessment and treatment of ASD and other mental health conditions in adults.

We have over 20 years of experience in the development and delivery of diagnostic and specially adapted interventions and therapies for adults with ASD. We use gold-standard assessments and treatments in our work with patients and families.

Our evidence-based service provides assessment and treatment for people with:
  • Suspected or diagnosed ASD, including autism and Asperger’s syndrome.
  • ASD and additional mental health problems, including obsessive compulsive disorder, psychosis, depression and anxiety.
  • ASD and behaviour that challenges.
Our team includes internationally renowned clinicians. Our staff hold the world’s biggest grant for research into autism and have won the NHS Innovation of the Year award. We use person centred approaches, helping patients to improve their coping skills and daily living abilities according to individual need. We work closely with families and local  teams to support patients in their local communities.
