About Autism Diagnosis Diagnosis The Leeds Autism Diagnostic Service (LADS) provides assessment and diagnosis of people of all intellectual ability, who may have autism and live in Leeds. The assessment is provided by a team of mental health and learning disability professionals with specialist knowledge of autism. The service will accept referrals from Healthcare Professionals and also directly from individuals (self-referral) who would like an autism assessment. They will receive referrals for all adults over the age of 18 years regardless of their IQ. This includes people who also have a learning disability or other developmental conditions. The service aims to provide an initial assessment appointment within 12 weeks of referral, and provide a diagnosis within 26 weeks of referral. Visit the LADS website for more information.
