Autism Diagnostic Service Suffolk

  • Our Autism Diagnostic Service provides assessments to identify if a person has autism or not. We have a youth team who provide assessments for young people between the ages of 11 and 18. We have an adult team who provide assessments for those aged 18 and over. If we diagnose somebody with autism, we offer advice and short term limited support to help them, and their family, to understand their diagnosis. Our team will explore ways that might help manage difficulties or challenges faced at home, work or in education.

What this service offers

When we receive a referral form, we review the information.  If there is not enough information to show that an autism assessment is needed, we will not accept the referral. We might return the referral, ask for more information or send the referral to another service for support if we think this would be helpful.

When a referral is accepted the name of the person is placed on a waiting list for an autism assessment.  The waiting list is long, but we will see the person as soon as we can.  While the person is waiting, we provide information about what happens during an autism assessment and ask for the persons consent. When we are able to see the person, we will contact them or their parent/carer by telephone or letter and arrange where and when to meet.

We try to meet people as close to their home as possible. We have clinics in Bury St Edmunds, Stowmarket and Ipswich. 

Our teams complete a full assessment, working with the person and important people in their lives, before we decide if autism is the correct diagnosis for the person.

When the assessment is finished, we will write a report and send this to the person and their GP.  The report explains our decision and whether a diagnosis of autism has been given.
