Written by HealthAnswers editorial team Medically reviewed by [Dr Neil Singh MBChB - nMRCGP](https://healthanswers.co.uk/our-doctors/neil-singh/) · GMC 7039648 Reviewed 28 June 2026 ## Quick answer What is autism? Autism (autism spectrum disorder) is a lifelong neurodevelopmental difference affecting social communication, sensory processing, and patterns of behaviour or interests. It is not an illness to cure — support focuses on strengths and managing challenges. Signs include difficulty reading social cues, sensory sensitivities, strong routines, and intense interests. Children are often referred via GP or school to community paediatrics or CAMHS; adult diagnosis via NHS autism assessment teams — waiting lists can be long. Reasonable adjustments at school and work are legal rights. ## Who is this page for? This page is for people in the UK who want a plain-English overview of Autism, including when to seek help and what NHS care usually involves. It explains general information, not what is wrong with you personally. ## Who should skip this page? Skip this page if you need a diagnosis, a prescription, or emergency care. It cannot replace a GP, pharmacist, NHS 111 or 999. If you are in immediate danger, call 999; for urgent advice that is not life-threatening, call 111 in England, Scotland or Wales, or use your GP out-of-hours service in Northern Ireland.

When to see a GP about autism See a GP if a child is not meeting communication milestones, avoids eye contact persistently beyond toddlerhood, has severe meltdowns with routine change, or shows regression in language. Adults may seek assessment if lifelong social difficulty, masking exhaustion, or sensory overwhelm affects work and relationships. GP refers to local autism assessment pathway — child development service or adult neurodevelopmental team. ## Common questions about autism What are early signs of autism in children? Limited eye contact and shared attention, delayed speech or unusual language (echolalia, formal speech), not pointing to show interest by 18 months, repetitive play (lining up toys), strong need for sameness, sensory sensitivities — sound, texture, light — intense interests. Girls may mask more — diagnosis often later. Can adults be diagnosed with autism? Yes — increasingly recognised. Signs include lifelong difficulty with small talk and friendships, missing social rules, sensory overload in shops or offices, camouflaging (masking) leading to burnout, special interests providing deep expertise. NHS adult autism assessment via GP referral — waiting times vary by area. How is autism assessed on the NHS? Multidisciplinary team — paediatrician, speech and language therapist, clinical psychologist, sometimes OT. Developmental history, ADOS or equivalent structured observation, school/nursery reports, differential diagnosis (ADHD, language disorder, anxiety). Adult pathway similar with self-report and informant history. Is autism the same as Asperger syndrome? Asperger syndrome is no longer a separate diagnosis — folded into autism spectrum disorder in DSM-5 and ICD-11. Previously described autistic people without intellectual disability or language delay — now all under autism with support needs specified. What support is available after an autism diagnosis? EHCP for school if needed, speech and language therapy, occupational therapy for sensory strategies, social skills groups, parent training, reasonable adjustments at work (Equality Act), Access to Work grants, local autism charities — National Autistic Society local branches. ## Sources - [NHS — Autism](https://www.nhs.uk/conditions/autism/) - [NICE — Autism spectrum disorder in under 19s](https://www.nice.org.uk/guidance/cg170) - [National Autistic Society](https://www.autism.org.uk/)
