Key areas: Autism Spectrum Disorder and Mental Health


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.  At least 50 percent of patients referred to us have undiagnosed additional mental health difficulties; the identification of these are critical to a patient’s well being.

Our National Autism Unit and Autism Assessment and Behavioural Genetics Clinic have over 20 years of experience in the development and delivery of diagnostic and specially adapted interventions/therapies for adults with ASD.

Our evidence-based services provide 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 for diagnostic assessment which includes feedback on the same day. This 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 people to improve their coping skills and daily living abilities according to individual need. We work closely with families and local teams to support people in their local communities.

Ellen’s story

We saw a psychiatrist, who diagnosed him with Asperger’s syndrome and referred him to a local psychiatric hospital. He was going there once every three weeks, but they weren’t offering him treatment. He also became violent at home, which made him impossible to live with…
