Overview
More adults than ever are being diagnosed, often after a child, partner or colleague is identified. A late diagnosis can be life-changing — bringing relief, grief, identity work and access to support.
Key points to understand
- NHS adult autism assessments are commissioned locally; waits range from months to years.
- Right to Choose (England) allows referral to providers like Psychiatry-UK, ProblemShared and Clinical Partners — usually faster than local NHS.
- Self-identification is valid and respected by the autistic community while you wait for formal assessment.
- Adult diagnosis does not automatically unlock services — but it does unlock the Equality Act 2010 and Access to Work.
Practical strategies that help
- Use AQ-10 or RAADS-R as a starting screen.
- Document your developmental history (school reports, parents' memories).
- Join late-diagnosed adult peer groups — the identity shift is significant.
Common challenges to be aware of
- Some assessors lack experience of adult, female or PDA presentations — choose carefully.
- Post-diagnosis support from the NHS is often minimal; community is essential.
