If you are an adult (18 or over) in Northamptonshire and think you may be autistic or have ADHD, this guide explains how the NHS assessment works. You cannot refer yourself, so it explains how to ask a professional to refer you to the NHFT Adult ADHD, Autism and Tourette's Team (AAATT).

Step by step

  1. Understand which service is right for you

    The NHFT Adult ADHD, Autism and Tourette's Team (AAATT) assesses adults aged 18 and over for autism (without a learning disability), ADHD and/or Tourette's syndrome. If you have both autism and a learning disability, you are usually supported by the Community Team for People with Learning Disabilities (CTPLD) instead. If you are not sure, your GP can advise.

  2. Book a GP appointment to talk about an assessment

    Make an appointment with your GP and explain why you think you may be autistic or have ADHD. It helps to note down examples from everyday life, childhood and work, and how it affects you. You can bring someone with you for support.

  3. Ask your GP to refer you

    The AAATT does not accept self-referrals. Referrals are made by GPs, the community mental health team, social services, or an appropriate member of hospital or care-unit staff. Ask your GP to make the referral to the NHFT Adult ADHD, Autism and Tourette's Team.

  4. Consider NHS Right to Choose if the local wait is long

    If a GP refers you for a non-urgent physical or mental health condition, you usually have a legal right to choose the service you are referred to. For autism and ADHD assessment this can mean an alternative NHS-funded provider instead of the local NHFT team, and the assessment stays free of charge. You cannot self-refer: ask your GP to make the referral, usually on the chosen provider's own form, and you can only be on one waiting list at a time. This right does not apply to emergency care. For ADHD, check the medication shared-care position first, and see this pack's child-and-adult autism and ADHD assessment guides for how to pick a provider.

  5. Wait for the team to contact you

    After the referral is accepted, the team will be in touch about next steps. There can be a wait for assessment. If your situation changes or you are struggling in the meantime, contact your GP, and if you are in mental health crisis call NHS 111 (select the mental health option) or 999 in an emergency.

  6. Attend the diagnostic assessment

    The AAATT carries out a diagnostic assessment. You may be asked about your history, everyday life and any difficulties. Ask for any reasonable adjustments you need for the appointment, such as a written summary, extra time, or having a supporter with you.

  7. Get post-diagnosis support

    If you receive a diagnosis, the team offers post-diagnosis support which can include psychoeducation, medication management, and short-term one-to-one or group support. Ask what is available to you and how to access it.
