The Autism Assessment and Behavioural Genetics Clinic is a national, specialist service based at the Maudsley 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 neurodevelopmental disorders in adults.

We have over 20 years of experience in the development and delivery of diagnostics and specially adapted interventions and therapies for adults with ASD. We use gold-standard assessments and treatments in our work with patients and families. At least 50 percent of patients referred to us have undiagnosed additional mental health difficulties; the identification of these is critical to a patient’s well-being.

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.
  • Suspected chromosomal abnormalities or single gene disorders, including 22q deletion and fragile X syndrome.
  • ASD and behaviour that challenges.
  • Other behavioural phenotypes of significant genetic origin.

We offer a one-stop appointment to all outpatients who require diagnostic assessment. This includes feedback on the day, which is particularly useful for those who travel long distances.

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.
