Global perspective

One spectrum. Many lived experiences.

Autism is a neurodevelopmental condition. Communication, sensory experiences and support needs vary between people and can change throughout life. Understanding the individual comes first.

01

Recognise individual needs

Look beyond a diagnosis to communication preferences, sensory needs, strengths and personal goals.

02

Connect care and everyday life

Bring health, education, family support and community participation into the same conversation.

03

Make the ecosystem visible

Connect organisations, research and funding to understand where support is available and where gaps remain.

Global perspective

Autism is identified far more often than 20 years ago

The Global Burden of Disease study estimates 61.8 million autistic people worldwide and 11.5 million years lived with disability. In the US, identification among 8-year-olds rose almost five-fold between 2000 and 2022, driven largely by wider criteria and better screening.

Trend

How identification has grown

The CDC has tracked autism among 8-year-olds every two years since 2000. Each report has found a higher share, with the steepest rise after 2016. Similar growth appears in Swedish, UK and Australian records.

The Autism support journey

From recognising differences to assessment, personalised support and transitions into adulthood, continuity matters. Explore the team’s pathway and reported access gaps.

Diagnosis

Where diagnosis is delayed

From the first concern to support at school: the steps a family goes through in the US, and where time is lost.

Where time is lost

age in months
  • First concerns usually appear at 16–30 months
  • 1Screening is recommended at 18 and 24 months (AAP)
  • 2By 36 months only 50.3% of autistic children have had a developmental evaluation
  • 3Median age at diagnosis: 47 months (43 with intellectual disability, 49 without), down from 53 months in 2006
  • Range across ADDM sites: 36 months (California) to 69.5 months (Texas, Laredo)
  • About 2 years pass between the last recommended screening and the median diagnosis

The challenge

Where autism care still falls short

Late diagnosis, long waits, few treatments and fragmented data hold back care, research and investment.

47 monthsmedian age at diagnosis, US

Diagnosis comes late

Screening is recommended at 18 and 24 months, yet half of children have no developmental evaluation by age three.

86.8%of open referrals wait 13+ weeks, England

Long waits for assessment

Nearly 295,000 people were waiting for an autism assessment in England in June 2026, up from 213,000 in December 2024.

0drugs for core features

Few treatment options

Two drugs are approved for irritability associated with autism; none treats its core features, and recent Phase 2 and 3 trials missed their goals.

Fragmenteddata across countries and sectors

No single view of the field

Prevalence, trials, companies and funding are tracked in separate systems with different definitions, making gaps and opportunities hard to see.

Autism market in charts

A growing market for diagnostics and care

Care services, diagnostic tools and a small drug pipeline attract both private equity and venture capital. Vendor reports agree on the size of the treatment and diagnostics markets; care services, the largest part of spending, still has no published market estimate.

Clinical research

Where autism clinical trials happen

The United States hosts about half of all autism trials, and European countries together about a fifth. Since 2019 the field has added around 170 new studies a year, most of them led by universities and hospitals.

Approved products

What the FDA has cleared and approved

AI-based and eye-tracking diagnosis aids now help clinicians diagnose autism earlier, while drug approvals remain limited to irritability.

FDA decisions over time

Square: drug (supplemental NDA) · circle: device (510(k) or De Novo)
Wellcovorin (leucovorin, 2026) is indicated for cerebral folate deficiency, not autism. Other regulators (EMA, MHRA, Health Canada, PMDA) are being added.
Practical priorities

Better support, throughout life

Research and collaboration should reflect the priorities of autistic people, with a focus on access, participation and quality of life.

01

Accessible assessment

Clear referral routes and assessment adapted to individual communication and sensory needs.

02

Personalised support

Individual goals, communication support and appropriate care for co-occurring health needs.

03

Lifelong inclusion

Better connections between education, employment, adult services and community life.
